The first version of MoveEye will be two-dimensional, with the user manipulating objects on a plane suspended in space. Later, Tarsier will add 3D capability so users can feel as if they're reaching into an interface that has more than one layer.

Using gestures to control something on a screen is not new. Both Nintendo's Wii and Microsoft's Kinect let users play games and carry out other tasks with movements and gestures. But MoveEye can better read hand gestures as well as where those gestures are directed, Wala said. That precision is necessary for the full range of actions on a computer, such as grabbing a small object, he said.

MoveEye achieves this by viewing the screen from the user's perspective. While the Wii system follows a controller in the user's hand and Kinect faces the user and watches body movements, MoveEye captures the user's own perspective through the stereoscopic camera in its glasses. That, and the eye-tracking sensors, help to tell the system precisely where each element on the screen appears from the user's perspective, Wala said. Algorithms and software developed by Tarsier do the rest.

Though games on big-screen TVs are one obvious use for MoveEye, Tarsier has higher ambitions as well. A 3D MoveEye interface could be used for military applications such as combat simulations and controlling bomb-defusing robots, Wala said. In medicine, it could allow doctors to virtually reach inside 3D MRI scans, he said.

At Demo, Tarsier will show MoveEye working with a wired version of the glasses and controlling a customized OS based on the Boxee freeware platform. But for its eventual product, the company may use a derivative of Android and allow selected Android apps and games to work with MoveEye, Wala said. Whatever platform it uses, Tarsier believes it can offer interface innovations that make computing easier than ever.
