CONTROLLING THE MOUSE WITH YOUR EYE


Most of the user of the computer suffer pain in the wrist or in fingers due to over usage of pc or laptops by infront of them whole day by typing and moving the mouse. Due to this some of the user gets muscular pain etc. The research scholars of imperial college in London have found out a solution to this problem that is controlling the mouse with your eye.
                             A small device is used for this purpose which is called as GT3D device. This device consists of a pair of glasses (like the coolers) that user must wear when you need to move the mouse with eye. And also two fast control cameras are used to keep track of your eye. The camera constantly records the movement of the pupil and moves the cursor to the direction where it points to. This device is on the development stage so the scholars demonstrated the effective usage of the device by a pong game. They also demonstrated how the surfing in net could be done using this system. The previous version devices of GT3D has some disadvantage such as you need to look on an icon for a prolonged period of time inorder to open the application of the icon, due to this when you stare on the desktop screen for some time then this automatically opens. Inorder to avoid this problem  GT3D device is sensitive so that just a look at that opens the application and they have attached the 3d facility so that the camera could detect whether your are just looking simply on desktop screen  or the user  need to open the application. The cost of this GT3D device is much cheaper (40$) than the other system input that we use.
