Swedish company Tobii has shrunk the size and updated the software of its eye-tracking device and hopes to see the technology go into use in the medical, design, presentation, surveillance and gaming industries.
The company says its technology is now more responsive and can fit in a wider range of hardware, including gaming machines.
The technology (pictured) uses two infrared projectors to illuminate the users' pupils and two small cameras to record their positions as they change, then feed this data to the onboard processors, which then output the person's eye position, pupil size and gaze position.
The new module is much, much smaller than its predecessor, which Tobii demonstrated at the show last year. It was also used in a prototype eye-tracking Lenovo laptop, which was tried out by ZDNet UK editorial staff in our offices.
