Powered by EO: TM4 from EyeTech Digital Systems

The TM4 eye tracker from EyeTech Digital Systems uses one of Edmund Optics' micro-video lenses, cameras, and an infrared (IR) sensor to track the movement of the eye, enabling individuals who are severely paralyzed, or suffer from RSI or carpal tunnel syndrome to control their computer hands-free using only their eye movements. With the aid of this assistive technology, individuals can perform mouse functions including left and right click, double click, drag, zoom and much more. The TM4 eye tracker has been optically designed with compact and light-weight optical elements, making it ideal for large volume implementation. With the TM4's high portability and low price point, EyeTech Digital Systems is looking to improve the quality of life for millions of people worldwide by making this assistive technology accessible to everyone. Randall Hinton, Solutions Engineer at Edmund Optics, demonstrates how to navigate the EO website and open Zemax optical design software using only a few eye movements.
