Immersion Files Suit Against Microsoft and Sony Computer Entertainment for
Patent Infringement

SAN JOSE, Calif.-- Feb. 11, 2002--Immersion Corp. (Nasdaq:IMMR - news), a
leading developer and licensor of haptic feedback technology, today announced it
has filed a patent infringement lawsuit against Microsoft Corporation, Sony
Computer Entertainment, Inc, and Sony Computer Entertainment of America, Inc.
Immersion's complaint, filed in the U.S. District Court for the Northern
District Court of California, alleges infringement by Microsoft's and Sony's use
of haptic technology in their popular video gaming consoles, such as the
Microsoft Xbox(TM) and Sony PlayStation(R) and PlayStation(R)2 videogame
systems, and associated controllers, accessories and software games with touch
feedback.

Based on the Greek word "haptesthai," meaning touch, haptic technology enables
people to feel touch sensations while interacting with a digital display, like a
computer screen and a hardware device such as a joystick or mouse. Immersion's
haptic technology, brand-named TouchSense(TM), enhances the user experience with
sight, sound and touch simultaneously.

Since 1993, Immersion's engineering team has been focused on the development of
haptic innovations for the computing, entertainment, medical simulation, 3D and
automotive markets. Market leaders such as Logitech, Kensington and BMW are
among Immersion's many licensees. The company's intellectual property portfolio
relates to a wide range of innovations for enabling haptics across broad
applications and markets. Immersion and its wholly-owned subsidiaries hold over
150 issued patents worldwide.

Immersion's technology is licensed extensively within the computing and
entertainment industry. Immersion has expanded its licensees into the gaming
console market with partners such as MadCatz, Saitek and others. These partners
have developed more than 40 touch-enabled gaming peripherals currently shipping
for the Microsoft Xbox and Sony PlayStation platforms.

"The development and licensing of our haptic technology is the foundation of our
business," said Bob O'Malley, chairman and chief executive officer of Immersion.
"After extensive attempts to settle this infringement issue through
negotiations, we decided to file the suit today to enforce our intellectual
property rights."
