Tobii devices may not have featured in your must-buy devices list, until now. The Swedish company is all set to change the game with its newly launched eye-controlled user interface in its C12, which is a Windows-based tablet-like speech generation device. The C12 has been developed for users with physical disabilities.

According to reports, the new revolutionary technology will enable users to control "the C12's pointer by simply moving their eyes and clicks are performed by blinking" and that the device also allows "multiple users to calibrate their eye movements for the C12."

Although the Windows-based device was released in 2009, C12 needed to make some enhancements in its GSM module and recently showed up on the Federal Communications Commission (FCC) website. Now, FCC has given approval for the latest eye-tracking technology.

The technology was originally developed back in 2001, claims Tobii. The official website of the company explains how the eye tracking technology "estimates the point of gaze with extreme accuracy using image sensor technology that finds the user's eyes and calculates the point of gaze with mathematical algorithms."

Additionally, the device will also have a separate technology called head movement box - an imaginary box that will enable a user to move his head and still be tracked by the device. Reportedly, the company has different head movement boxes depending on the size of the model. Tobii also informs that a larger head movement box gives its users greater freedom to move thier heads with ease.
