Researchers from Imperial College London (UK) created a software and hardware system that allows you to interact with your computer only one eye.
System GT3D, tracks the position of the pupils, allows you to move the cursor on the screen to scroll through web pages, and even typing. To press a particular button is enough to wink one eye: experts explain that they refused to use Blink, because it is a natural process, and therefore can be false positives.
One of the main advantages of the design - a small price: a part GT3D includes two quick camera cost about $ 30 each and rim glasses for $ 5 on which the cameras are fixed. Data can be transferred to a computer over a wireless communication Wi-Fi, or USB-through connection. For the processing of information and its transformation into control commands responsible specialized software.
The demonstration showed how using GT3D you can play the classic game of Pong (cm. Video). Theoretically, using a more accurate calibration, the system can be trained to estimate the distance to the object to which the user is looking. This allows you to use complex, for example, to control the view by electronic wheelchair.
Means for controlling the computer with the help of developing eye and other companies. So, Tobii Technology has recently shown a system Tobii IS-2 Eye Tracker, which records changes in the viewing direction by using an invisible infrared radiation to humans and two small cameras. The complex can be integrated with a variety of equipment, such as slot machines, personal computers, medical devices, information stands and so on.
