Revenue, Initial Application Period Cumulative Effect Transition [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	2. ACCOUNTING STANDARDS Recently Issued Accounting Pronouncements Leases In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02 (Topic 842) Leases , which requires lessees to recognize a right-of-use asset and lease liability for most lease arrangements. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and must be adopted using the modified retrospective approach. The Company intends to adopt the standard on the effective date of December 30, 2018. The Company is currently evaluating the potential changes from this ASU to its future financial reporting and disclosures and designing and implementing related processes and controls. Recently Adopted Accounting Pronouncements Recognition and Measurement of Financial Assets and Liabilities The Company adopted ASU No. 2016-01 and the related amendments on December 31, 2017 (the first day of the Company's fiscal year 2018). This standard amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The Company adopted the measurement alternative for equity investments without readily determinable fair values (often referred to as cost method investments) on a prospective basis. As a result, these investments will be revalued upon occurrence of an observable price change for similar investments and for impairments. The Company expects that the adoption of this guidance may have a material effect on its financial statements on an ongoing basis. Revenue from Contracts with Customers The Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) effective December 31, 2017 and applied the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company expects the impact of the adoption of the new standard to be material to the Company's results of operations on an ongoing basis. Significant Accounting Policies Update The Company's significant accounting policies are detailed in "Note 1: Summary of Significant Accounting Policies" of our Annual Report on Form 10-K for the year ended December 30, 2017. Significant changes to the Company's accounting policies as a result of adopting Topic 606 are discussed below. Revenue Recognition The vast majority of our revenues are from orders received from our customers for the purchase of wearable technology components which can be integrated to create headset systems. We also have development contracts for the design, manufacture and modification of products for the U.S. government or a prime contractor for the U.S. government (“U.S. government”) or for a customer that sells into the industrial or consumer markets. The Company's contracts with the U.S. government are typically subject to the Federal Acquisition Regulations (“FAR”) and are priced based on estimated or actual costs of producing goods. The FAR provides guidance on the types of costs that are allowable in establishing prices for goods provided under U.S. government contracts. The pricing for non-U.S. government contracts is based on the specific negotiations with each customer. Our fixed-price contracts with the U.S. government may result in revenue recognized in excess of amounts actually billed. We present the in excess of revenues over amounts actually billed as Contract assets on the balance sheet. Amounts billed and due from our customers are classified as receivables on the balance sheet. In some instances, the U.S. government retains a small portion of the contract price until completion of the contract. The portion of the payments retained until final contract settlement is not considered a significant financing component because the intent is to protect the customer. For contracts with the U.S. government, we typically receive interim payments either as work progresses, we achieve certain milestones or based on a schedule in the contract. We recognize a liability for these advance payments in excess of revenue recognized and present it as billings in excess of revenue recognized on the balance sheet. The advanced payment typically is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect us from the other party failing to adequately complete some or all of its obligations under the contract. For industrial and consumer purchase orders, we typically receive payments within 30 to 60 days of shipments of the product, although for some purchase orders, we may require an advanced payment prior to shipment of the product. To determine the proper revenue recognition method for complex contracts with the same customer, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate the combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. For most of our development contracts and contracts with the U.S government, the customer contracts with us to provide a significant service of integrating a set of components into a single unit. Hence, the entire contract is accounted for as one performance obligation. Less common, however, we may promise to provide distinct goods or services within a contract in which case we separate the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, we allocate the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. In cases where we sell standard products, the observable standalone sales are used to determine the standalone selling price. The Company recognizes revenue from a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. For certain contracts that meet the foregoing requirements, primarily international direct commercial and military sale contracts, we recognize revenue once we have obtained all regulatory approvals. Commencing in 2018 for certain contracts with the U.S. government, the Company recognizes revenue over time as we perform because of continuous transfer of control to the customer and the lack of an alternative use for the product. The continuous transfer of control to the customer is supported by liability clauses in the contract that allow the U.S. government to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. For contracts with commercial customers while the contract may have similar liability clause our products historically have an alternative use and thus, revenue is recognized at a point in time. In situations where control transfers over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost approach to measure the extent of progress towards completion of the performance obligation for our contracts because we believe it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure approach, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Accounting for design, development and production contracts requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. Due to the size and nature of the work required to be performed on many of our contracts, the estimation of total revenue and cost at completion is complicated and subject to many variables. Contract costs include material, labor and subcontracting costs, as well as an allocation of indirect costs. We have to make assumptions regarding the number of labor hours required to complete a task, the complexity of the work to be performed, the availability and cost of materials, and performance by our subcontractors. For contract change orders, claims or similar items, we apply judgment in estimating the amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is considered probable. If our estimate of total contract costs or our determination of whether the customer agrees that a milestone is achieved is incorrect, our revenue could be overstated or understated and the profits or loss reported could be wrong. For our commercial customers, the Company's revenue is recognized when obligations under the terms of a contract with our customer is satisfied; generally this occurs with the transfer of control of the Company's products or services. Revenue is recorded as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Provisions for product returns and allowances are recorded in the same period as the related revenues. We analyze historical returns, current economic trends and changes in customer demand and acceptance of product when evaluating the adequacy of sales returns and other allowances. Certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products. Sales to distributors are primarily made for sales to the distributors' customers and not for stocking of inventory. We delay revenue recognition for our estimate of distributor claims of right of return on unsold products based upon our historical experience with our products and specific analysis of amounts subject to return based upon discussions with our distributors or their customers. Sales, value add and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. The rights and benefits to the Company's intellectual property are conveyed to certain customers through technology license agreements. These agreements may include other performance obligations including the sale of product to the customer. When the license is distinct from other obligations in the agreement, the Company treats the license and other performance obligations as separate performance obligations. Accordingly, the license is recognized at a point in time or over time based on the standalone selling price. The sale of materials are recognized at a point in time, which occurs with the transfer of control of the Company's products or services. In certain instances, the Company is entitled to sales-based royalties under license agreements. These sales-based royalties are recognized when they are earned. The cumulative effect of the changes made to the Company's consolidated December 31, 2017 balance sheet for the adoption of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) was as follows: Balance Sheet Balance at December 30, 2017 Adjustments due to ASC 606 Balance at December 31, 2017 Assets Contract assets and unbilled receivables $ 704,863 $ 2,850,274 $ 3,555,137 Inventory 5,080,797 (1,082,629 ) 3,998,168 Other assets 3,842,068 400,000 4,242,068 Liabilities Contract liabilities and billings in excess of revenue earned 896,479 (891,737 ) 4,742 Stockholders’ equity Accumulated Deficit $ (240,121,901 ) $ 3,059,382 $ (237,062,519 ) In accordance with the new revenue standard requirements, the impact of adoption on the Company's condensed consolidated statement of operations and condensed balance sheets was as follows: For the period ended March 31, 2018 Statement of Operations As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Net product revenues $ 5,044,809 $ 6,505,343 $ (1,460,534 ) Research and development revenues 608,811 695,355 (86,544 ) Cost of product revenues 4,062,191 5,069,765 (1,007,574 ) Net loss attributable to the controlling interest $ (5,536,278 ) $ (4,996,773 ) $ (539,505 ) For the period ended March 31, 2018 Balance Sheet As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Assets Contract assets and unbilled receivables $ 2,479,062 $ 1,089,322 $ 1,389,740 Inventory 3,773,305 3,848,359 (75,054 ) Other assets 4,194,219 3,794,219 400,000 Liabilities Contract liabilities and billings in excess of revenue earned 384,073 1,189,266 (805,193 ) Stockholders’ equity Accumulated deficit $ (242,598,797 ) $ (245,082,132 ) $ 2,483,335 See Note 11. Segments and Disaggregation of Revenue for additional information regarding the disaggregation of the Company's revenue by major source and the Company's updated accounting policy for revenue recognition. Contract Assets Contract assets include unbilled amounts typically resulting from sales under contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts may not exceed their net realizable value. Contract assets are generally classified as current. The Company classifies the noncurrent portion of contract assets under other assets in its condensed consolidated balance sheets. Contract Liabilities Contract liabilities consist of advance payments and billings in excess of cost incurred and deferred revenue. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for which work has not been performed and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity ("IDIQ")). As of March 31, 2018 , the aggregate amount of the transaction price allocated to remaining performance obligations was $2.7 million . The Company expects to recognize revenue on the remaining performance obligations over the next 12 months.

Cash and Equivalents and Marketable Securities Disclosure [Abstract]
CASH AND EQUIVALENTS AND MARKETABLE SECURITIES	CASH AND CASH EQUIVALENTS AND MARKETABLE SECURITIES The Company considers all highly liquid, short-term debt instruments with original maturities of three months or less to be cash equivalents. Marketable debt securities consist primarily of commercial paper, medium-term corporate notes, and U.S. government and agency backed securities. The Company classifies these marketable debt securities as available-for-sale at fair value in “Marketable debt securities, at fair value”. The Company records the amortization of premium and accretion of discounts on marketable debt securities in the results of operations. The Company uses the specific identification method as a basis for determining cost and calculating realized gains and losses with respect to marketable debt securities. The gross gains and losses realized related to sales and maturities of marketable debt securities were not material during the three months ended March 31, 2018 and the year ended December 30, 2017 .

The Company assesses whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the balance sheet date. Under these circumstances OTTI is considered to have occurred (1) if the Company intends to sell the security before recovery of its amortized cost basis; (2) if it is “more likely than not” the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. The Company further estimates the amount of OTTI resulting from a decline in the creditworthiness of the issuer (credit-related OTTI) and the amount of non credit-related OTTI. Non credit-related OTTI can be caused by such factors as market illiquidity. Credit-related OTTI is recognized in earnings while non credit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (loss). The Company did not record OTTI for the three months ended March 31, 2018 and April 1, 2017 .

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Financial instruments are categorized as Level 1, Level 2 or Level 3 based upon the method by which their fair value is computed. An investment is categorized as Level 1 when its fair value is based on unadjusted quoted prices in active markets for identical assets that the Company has the ability to access at the measurement date. An investment is categorized as Level 2 if its fair market value is based on quoted market prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, based on observable inputs such as interest rates, yield curves, or derived from or corroborated by observable market data by correlation or other means. An investment is categorized as Level 3 if its fair value is based on assumptions developed by the Company about what a market participant would use in pricing the assets. The following table details the fair value measurements of the Company’s financial assets: Fair Value Measurement March 31, 2018 Using: Total Level 1 Level 2 Level 3 Cash and Cash Equivalents $ 24,167,900 $ 24,167,900 $ — $ — U.S. Government Securities 29,418,278 3,987,510 25,430,768 — Corporate Debt 7,255,427 — 7,255,427 — Certificates of Deposit 199,890 — 199,890 — GCS Holdings 459,108 459,108 — — Equity Investment 3,900,000 — — 3,900,000 Warrant 1,949,816 — — 1,949,816 $ 67,350,419 $ 28,614,518 $ 32,886,085 $ 5,849,816 Fair Value Measurement December 30, 2017 Using: Total Level 1 Level 2 Level 3 Cash and Cash Equivalents $ 24,848,227 $ 24,848,227 $ — $ — U.S. Government Securities 34,725,811 6,927,323 27,798,488 — Corporate Debt 8,980,906 — 8,980,906 — Certificates of Deposit 200,740 — 200,740 — GCS Holdings 478,546 478,546 — — Warrant 2,000,000 — — 2,000,000 $ 71,234,230 $ 32,254,096 $ 36,980,134 $ 2,000,000 Transfers between levels of the fair value hierarchy are reported at the beginning of the reporting period in which they occur. Changes in Level 3 investments are as follows: December 30, 2017 Net unrealized gains/(losses) Purchases, issuances and settlements Transfers in and or out of Level 3 March 31, 2018 Equity Investments $ — $ — $ 3,900,000 $ — $ 3,900,000 Warrant 2,000,000 (50,184 ) — — 1,949,816 $ 2,000,000 $ (50,184 ) $ 3,900,000 $ — $ 5,849,816 The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of their short-term nature. If accrued liabilities were carried at fair value, these would be classified as Level 2 in the fair value hierarchy. Marketable Debt Securities The corporate debt consists of floating rate notes with a maturity that is over multiple years but has interest rates that are reset every three months based on the then-current three-month London Interbank Offering Rate (three-month Libor). The Company validates the fair market values of the financial instruments above by using discounted cash flow models, obtaining independent pricing of the securities or through the use of a model that incorporates the three-month Libor, the credit default swap rate of the issuer and the bid and ask price spread of the same or similar investments which are traded on several markets. Warrant The Company has a warrant to acquire up to 15% of the next round of equity offered by a customer as part of the licensing of technology to the customer. The Company used the customer's capital structure, pricing of the shares being offered and the warrant from the customer's qualified financing round in determining the value of its warrant as of March 31, 2018 . The Company exercised the warrant in April 2018. Equity Investment The Company acquired an interest in an equity investment by transferring $1.0 million cash and certain intellectual property ("IP") in exchange for shares of common stock in the equity investment. The Company used the pricing of the shares being offered to other investors receiving shares of common stock in the same investment as well as a valuation if the IP to determine the value of its equity interest. As the value of the equity investment was determined to be $3.9 million and the carrying value of the IP on the Company’s books was zero , the Company recorded a gain of $2.9 million . The Company adopted ASU No. 2016-01 and the related amendments on December 31, 2017 (the first day of the Company's fiscal year 2018). This standard amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The Company adopted the measurement alternative for equity investments without readily determinable fair values (often referred to as cost method investments) on a prospective basis. As a result, these investments will be revalued upon occurrence of an observable price change for similar investments and for impairments.

Earnings Per Share [Abstract]
NET LOSS PER SHARE	NET LOSS PER SHARE Basic net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period less any unvested restricted shares. Diluted net loss per share is calculated using weighted-average shares outstanding and contingently issuable shares, less weighted-average shares reacquired during the period. The net outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock. The following were not included in weighted-average common shares outstanding-diluted because they are anti-dilutive or performance conditions have not been met at the end of the period: Three Months Ended March 31, 2018 April 1, 2017 Non-vested restricted common stock 3,454,274 3,067,674

STOCKHOLDERS' EQUITY AND STOCK-BASED COMPENSATION	STOCKHOLDERS' EQUITY AND STOCK-BASED COMPENSATION Non-Vested Restricted Common Stock The fair value of non-vested restricted common stock awards is generally the market value of the Company’s common stock on the date of grant. The non-vested restricted common stock awards require the employee to fulfill certain obligations, including remaining employed by the Company for one , two or four years (the vesting period) and in certain cases also require meeting either performance criteria or the Company’s stock achieving a certain price. For non-vested restricted common stock awards which solely require the recipient to remain employed with the Company, the stock compensation expense is amortized over the anticipated service period. For non-vested restricted common stock awards which require the achievement of performance criteria, the Company reviews the probability of achieving the performance goals on a periodic basis. If the Company determines that it is probable that the performance criteria will be achieved, the amount of compensation cost derived for the performance goal is amortized over the anticipated service period. If the performance criteria are not met, no compensation cost is recognized and any previously recognized compensation cost is reversed. Restricted stock activity was as follows: Shares Weighted Balance, December 30, 2017 2,629,274 $ 3.31 Granted 1,405,000 2.17 Forfeited (560,000 ) 4.15 Vested (20,000 ) 4.22 Balance, March 31, 2018 3,454,274 $ 2.71 On December 31, 2017, the Company amended the employment agreement with our CEO Dr. John Fan to expire on December 31, 2020 and as part of the amendment issued restricted stock grants. Of the restricted stock grants issued to Dr. Fan, 640,000 shares will vest upon the first 20 consecutive trading day period following the grant date during which the Company's common stock trades at a price equal to or greater than $5.25 , 150,000 shares will vest at the end of the first 20 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $6.00 , and 150,000 shares will vest at the end of the first 20 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $7.00 . All of the grants are subject to certain acceleration events and expire on December 31, 2020. The total fair value of these awards on December 31, 2017 was $1.7 million . The value of restricted stock grants that vest based on market conditions is computed on the date of grant using the Monte Carlo model with the following assumptions: For the period ended March 31, 2018 Performance price target $ 5.25 $ 6.00 $ 7.00 Expected volatility 48.3 % 48.3 % 48.3 % Interest rate 1.97 % 1.97 % 1.97 % Expected life (years) 3 3 3 Dividend yield — % — % — % Stock-Based Compensation The following table summarizes stock-based compensation expense within each of the categories below as it relates to non-vested restricted common stock awards for the three months ended March 31, 2018 and April 1, 2017 (no tax benefits were recognized): Three Months Ended March 31, 2018 April 1, 2017 Cost of product revenues $ 110,226 $ 104,092 Research and development 274,316 218,558 Selling, general and administrative 1,014,873 969,455 Total $ 1,399,415 $ 1,292,105 Unrecognized compensation expense for non-vested restricted common stock as of March 31, 2018 totaled $7.7 million and is expected to be recognized over a weighted average period of approximately two years.

Product Warranties Disclosures [Abstract]
ACCRUED WARRANTY	ACCRUED WARRANTY The Company typically warrants its products against defect for 12 to 15 months , however, for certain products a customer may purchase an extended warranty. A provision for estimated future costs and estimated returns for credit relating to such warranty is recorded in the period when product is shipped and revenue recognized, and is updated as additional information becomes available. The Company’s estimate of future costs to satisfy warranty obligations is based primarily on historical warranty expense experienced and a provision for potential future product failures. Changes in the accrued warranty for the three months ended March 31, 2018 are as follows: Balance, December 30, 2017 $ 649,000 Additions 64,000 Claims (114,000 ) Balance, March 31, 2018 $ 599,000 Extended Warranties Deferred revenue represents the purchase of extended warranties by the Company's customers. The Company recognizes revenue from an extended warranty on the straight-line method over the life of the extended warranty, which is typically 12 to 15 months beyond the standard 12 -month warranty. The Company classifies the current portion of deferred revenue under other accrued liabilities in its condensed consolidated balance sheets. The Company currently has $0.7 million of deferred revenue related to extended warranties.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company did not record a tax provision for the three months ended March 31, 2018 . The Company’s tax provision of approximately $1.1 million for the three months ended April 1, 2017 , represents the net benefit of $0.1 million for foreign income taxes including interest income on intercompany loans, uncertain tax positions and a benefit for the net reduction in estimated foreign withholding. In addition, as a result of the acquisition of NVIS, Inc. in the first quarter of 2017, we recognized $1.1 million of deferred tax liabilities which provides evidence of recoverability of our net deferred tax assets that previously carried a full valuation allowance. We reduced the valuation allowance on our net deferred tax assets in the amount of $1.1 million and such reduction was recognized as a benefit for income taxes for the three months ended April 1, 2017 . As of March 31, 2018 , the Company has available for tax purposes U.S. federal NOLs of approximately $165.0 million expiring 2022 through 2037. The Company has recognized a full valuation allowance on its domestic and certain foreign net deferred tax assets due to the uncertainty of realization of such assets. Ownership changes, as defined by the Internal Revenue Code, may substantially limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income. The ownership change in 2017 did not result in an annual net operating loss limitation as the acquired entity was an S Corporation and did not have loss carryforwards. Subsequent ownership changes could affect the limitation in future years. Such annual limitations could result in the expiration of net operating loss and tax credit carryforwards before utilization. The tax years 2001 through 2016 remain open to examination by major taxing jurisdictions to which the Company is subject to United States federal tax. These periods have carryforward attributes generated in years past that may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they have or will be used in a future period. State statutes are generally shorter with shorter carryforward periods. The Company is currently not under examination by the Internal Revenue Service and is currently under examination by Massachusetts for the 2013 tax year. The Company recognizes both accrued interest and penalties related to its uncertain tax positions related to intercompany loan interest and potential transfer pricing exposure related to its Korean subsidiary. The Company has concluded that it does not maintain its permanent reinvestment assertion with regard to the unremitted earnings of its Korean subsidiary. As such, it accrues U.S. tax for the possible future repatriation of these unremitted foreign earnings. If the Company were to repatriate these earnings, it expects to have foreign withholding at a rate of 16.5% and does not expect any taxes to be paid in the U.S when repatriated as it currently is expected to be a return of capital.

LITIGATION	LITIGATION The Company may engage in legal proceedings arising in the ordinary course of business. Claims, suits, investigations and proceedings are inherently uncertain and it is not possible to predict the ultimate outcome of such matters and our business, financial condition, results of operations or cash flows could be affected in any particular period. BlueRadios, Inc. v. Kopin Corporation, Civil Action No. 16-02052-JLK (D. Col.): On August 12, 2016, BlueRadios, Inc. ("BlueRadios") filed a complaint in the U.S. District Court for the District of Colorado, alleging that the Company breached a contract between it and BlueRadios concerning a joint venture between the Company and BlueRadios to design, develop and commercialize micro-display products with embedded wireless technology referred to as “Golden-i”, breached the covenant of good faith and fair dealing associated with that contract, breached its fiduciary duty to BlueRadios, and misappropriated trade secrets owned by BlueRadios in violation of Colorado law (C.R.S. § 7-74-104(4)) and the Defend Trade Secrets Act (18 U.S.C. § 1836(b)(1)). BlueRadios further alleges that the Company was unjustly enriched by its alleged misconduct, BlueRadios is entitled to an accounting to determine the amount of profits obtained by the Company as a result of its alleged misconduct, and the inventorship on at least ten patents or patent applications owned by the Company need to be corrected to list BlueRadios’ employees as inventors and thereby list BlueRadios as co-assignees of the patents. BlueRadios seeks monetary, declaratory, and injunctive relief. On October 11, 2016, the Company filed its Answer and Affirmative Defenses. The parties are in the midst of discovery, with the close of discovery currently set for July 2, 2018. A trial date has not yet been set by the Court. The Company has not concluded a loss from this matter is probable; therefore, we have not recorded an accrual for litigation or claims related to this matter for the period ended March 31, 2018 . The Company will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable.

RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company may from time to time enter into agreements with shareholders, affiliates and other companies engaged in certain aspects of the display, electronics, optical and software industries as part of our business strategy. In addition, the wearable computing product market is relatively new and there may be other technologies the Company needs to purchase from affiliates in order to enhance its product offering. The Company and Goertek have entered into agreements to jointly develop and commercialize a range of technologies and wearable products. These include: a mutually exclusive supply and manufacturing arrangement for a certain display product for twenty four months after mass production begins; an agreement that provides the Company with the right of first refusal to invest in certain manufacturing capacity for certain products with Goertek; an agreement whereby Goertek will provide system level original equipment manufacturing services for the Company's wearable products; an arrangement whereby the Company will supply display modules for Goertek's virtual reality and augmented reality products; and other agreements related to promotion around certain products as well as providing designs relating to head mounted displays.

Revenue, Initial Application Period Cumulative Effect Transition [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The vast majority of our revenues are from orders received from our customers for the purchase of wearable technology components which can be integrated to create headset systems. We also have development contracts for the design, manufacture and modification of products for the U.S. government or a prime contractor for the U.S. government (“U.S. government”) or for a customer that sells into the industrial or consumer markets. The Company's contracts with the U.S. government are typically subject to the Federal Acquisition Regulations (“FAR”) and are priced based on estimated or actual costs of producing goods. The FAR provides guidance on the types of costs that are allowable in establishing prices for goods provided under U.S. government contracts. The pricing for non-U.S. government contracts is based on the specific negotiations with each customer. Our fixed-price contracts with the U.S. government may result in revenue recognized in excess of amounts actually billed. We present the in excess of revenues over amounts actually billed as Contract assets on the balance sheet. Amounts billed and due from our customers are classified as receivables on the balance sheet. In some instances, the U.S. government retains a small portion of the contract price until completion of the contract. The portion of the payments retained until final contract settlement is not considered a significant financing component because the intent is to protect the customer. For contracts with the U.S. government, we typically receive interim payments either as work progresses, we achieve certain milestones or based on a schedule in the contract. We recognize a liability for these advance payments in excess of revenue recognized and present it as billings in excess of revenue recognized on the balance sheet. The advanced payment typically is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect us from the other party failing to adequately complete some or all of its obligations under the contract. For industrial and consumer purchase orders, we typically receive payments within 30 to 60 days of shipments of the product, although for some purchase orders, we may require an advanced payment prior to shipment of the product. To determine the proper revenue recognition method for complex contracts with the same customer, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate the combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. For most of our development contracts and contracts with the U.S government, the customer contracts with us to provide a significant service of integrating a set of components into a single unit. Hence, the entire contract is accounted for as one performance obligation. Less common, however, we may promise to provide distinct goods or services within a contract in which case we separate the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, we allocate the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. In cases where we sell standard products, the observable standalone sales are used to determine the standalone selling price. The Company recognizes revenue from a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. For certain contracts that meet the foregoing requirements, primarily international direct commercial and military sale contracts, we recognize revenue once we have obtained all regulatory approvals. Commencing in 2018 for certain contracts with the U.S. government, the Company recognizes revenue over time as we perform because of continuous transfer of control to the customer and the lack of an alternative use for the product. The continuous transfer of control to the customer is supported by liability clauses in the contract that allow the U.S. government to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. For contracts with commercial customers while the contract may have similar liability clause our products historically have an alternative use and thus, revenue is recognized at a point in time. In situations where control transfers over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost approach to measure the extent of progress towards completion of the performance obligation for our contracts because we believe it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure approach, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Accounting for design, development and production contracts requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. Due to the size and nature of the work required to be performed on many of our contracts, the estimation of total revenue and cost at completion is complicated and subject to many variables. Contract costs include material, labor and subcontracting costs, as well as an allocation of indirect costs. We have to make assumptions regarding the number of labor hours required to complete a task, the complexity of the work to be performed, the availability and cost of materials, and performance by our subcontractors. For contract change orders, claims or similar items, we apply judgment in estimating the amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is considered probable. If our estimate of total contract costs or our determination of whether the customer agrees that a milestone is achieved is incorrect, our revenue could be overstated or understated and the profits or loss reported could be wrong. For our commercial customers, the Company's revenue is recognized when obligations under the terms of a contract with our customer is satisfied; generally this occurs with the transfer of control of the Company's products or services. Revenue is recorded as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Provisions for product returns and allowances are recorded in the same period as the related revenues. We analyze historical returns, current economic trends and changes in customer demand and acceptance of product when evaluating the adequacy of sales returns and other allowances. Certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products. Sales to distributors are primarily made for sales to the distributors' customers and not for stocking of inventory. We delay revenue recognition for our estimate of distributor claims of right of return on unsold products based upon our historical experience with our products and specific analysis of amounts subject to return based upon discussions with our distributors or their customers. Sales, value add and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. The rights and benefits to the Company's intellectual property are conveyed to certain customers through technology license agreements. These agreements may include other performance obligations including the sale of product to the customer. When the license is distinct from other obligations in the agreement, the Company treats the license and other performance obligations as separate performance obligations. Accordingly, the license is recognized at a point in time or over time based on the standalone selling price. The sale of materials are recognized at a point in time, which occurs with the transfer of control of the Company's products or services. In certain instances, the Company is entitled to sales-based royalties under license agreements. These sales-based royalties are recognized when they are earned. The cumulative effect of the changes made to the Company's consolidated December 31, 2017 balance sheet for the adoption of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) was as follows: Balance Sheet Balance at December 30, 2017 Adjustments due to ASC 606 Balance at December 31, 2017 Assets Contract assets and unbilled receivables $ 704,863 $ 2,850,274 $ 3,555,137 Inventory 5,080,797 (1,082,629 ) 3,998,168 Other assets 3,842,068 400,000 4,242,068 Liabilities Contract liabilities and billings in excess of revenue earned 896,479 (891,737 ) 4,742 Stockholders’ equity Accumulated Deficit $ (240,121,901 ) $ 3,059,382 $ (237,062,519 ) In accordance with the new revenue standard requirements, the impact of adoption on the Company's condensed consolidated statement of operations and condensed balance sheets was as follows: For the period ended March 31, 2018 Statement of Operations As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Net product revenues $ 5,044,809 $ 6,505,343 $ (1,460,534 ) Research and development revenues 608,811 695,355 (86,544 ) Cost of product revenues 4,062,191 5,069,765 (1,007,574 ) Net loss attributable to the controlling interest $ (5,536,278 ) $ (4,996,773 ) $ (539,505 ) For the period ended March 31, 2018 Balance Sheet As Reported Balances Without Adoption of ASC 606 Effect of Change Higher/(Lower) Assets Contract assets and unbilled receivables $ 2,479,062 $ 1,089,322 $ 1,389,740 Inventory 3,773,305 3,848,359 (75,054 ) Other assets 4,194,219 3,794,219 400,000 Liabilities Contract liabilities and billings in excess of revenue earned 384,073 1,189,266 (805,193 ) Stockholders’ equity Accumulated deficit $ (242,598,797 ) $ (245,082,132 ) $ 2,483,335 See Note 11. Segments and Disaggregation of Revenue for additional information regarding the disaggregation of the Company's revenue by major source and the Company's updated accounting policy for revenue recognition. Contract Assets Contract assets include unbilled amounts typically resulting from sales under contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts may not exceed their net realizable value. Contract assets are generally classified as current. The Company classifies the noncurrent portion of contract assets under other assets in its condensed consolidated balance sheets. Contract Liabilities Contract liabilities consist of advance payments and billings in excess of cost incurred and deferred revenue. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for which work has not been performed and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity ("IDIQ")). As of March 31, 2018 , the aggregate amount of the transaction price allocated to remaining performance obligations was $2.7 million . The Company expects to recognize revenue on the remaining performance obligations over the next 12 months.
