Eye-tracking technology looks to be one of the major tropes at CEATEC this year. One of many companies demoing a gaze-following setup is Fujitsu, which is showing off a prototype desktop PC with a built-in sensor and infrared LED. This configuration should be cheaper than many other eye-controlled solutions out there, as the components are integrated directly into the computer and no external hardware is needed. It's sweet and simple: the camera captures the reflection of light on the user's eye, and image processing technology then calculates the user's viewing angle to allow for hands-free navigation on-screen.
