Method and System for Controlling an Eye Tracking System
6 Jan 21
There is provided a method, system, and non-transitory computer-readable storage medium for controlling an eye tracking system to optimize eye tracking performance under different lighting conditions, by obtaining a first image captured using a camera associated with the eye tracking system, the first image comprising at least part of an iris and at least part of a pupil of an eye illuminated by an illuminator associated with the eye tracking system at a current power of illumination selected from a set of predetermined power levels; determining a contrast value between an the iris and the pupil in the image; and, if the contrast value deviates less than a preset deviation threshold value from a preset minimum contrast value, setting the current power of illumination of the illuminator to the other predetermined power level in the set of predetermined power levels.

Method and a HMD for Dynamically Adjusting a Hud
9 Dec 20
The embodiments herein relate to a method and a Head-Mounted-Device (HMD) for adaptively adjusting a Head-Up-Display (HUD), wherein the HUD includes a User Interface (UI) or HUD graphics the HMD comprising at least one eye tracker, a processor and a memory containing instructions executable by the processor wherein the HMD is operative to: determine a fixation distance, being a distance to a fixation point a user of said HUD is fixating on; and dynamically adjust said HUD by adjusting the position of the HUD UI, in front of each eye of the user, such that the HUD UI appears to be positioned at the fixation distance.
