Tobii is an eye-tracking technology company born in 2001, just after the dot-com bust and well before mouseless computing became a hot trend.
The technology tracks the movement of a user's eyes across a screen. At the Consumer Electronics Show (CES) in 2012, Tobii demonstrated the technology on a then-beta version of Microsoft's (Fortune 500) Windows 8 operating system. ,
A user can scroll, click or zoom just like a mouse by merely moving and blinking the eyes. Testers could also blast enemies in a computer game simply by glaring at them. But that consumer application was only a trade-show demo.
For now, Tobii is aimed at niche consumers and business customers. People who are disabled can use it for assistive communication, for example. Marketers can track where a person's eyes wander around a webpage, and doctors can zoom in on images with a mere glance while performing surgery.
IBM forecasts that in five years, computers will gain the five senses and experience the world as humans do.
