EyeTech has served the assistive technology market since its inception 20 years ago. Although the applications for eye tracking are growing and becoming more mainstream, EyeTech continues to find new applications to help those with physical disabilities. This year at CES, EyeTech brought a wheel chair and demonstrated driving it with your eyes. See this article from Arizona Tech Beat.
Of course VR HMDs are also a natural application for eye tracking, and EyeTech welcomed partner Quantum Interface as part of the EyeTech booth to show the latest developments. Click here for a write-up on this application from Tom's Hardware.
Also in the booth with EyeTech was a demo of EyeTech's VT3 eye tracker combined with King Devick software to detect and diagnose brain injuries.
The best part about CES, however, is meeting new people who envision embedding eye tracking into their latest application--applications that protect, teach, and enable.
