HI,
This for the guys who have interested in doing something for physically challenged people. This topic is to create a Mouse which is controlled with the help of eyes. This especially to help the people who have paralyzed hand's or the persons who lost the in an accident or during War.
Here the mouse is controlled with the help of eye movements. As we that the eye can rotate Horizontally as well as vertically at a time depending on this we use some optical sensors which are placed around the head(Brain) because as we know that the any we want to do those actions area controlled by the neurons that are present in brain. The Neurons that are present in brain are capable of generating some bio-potentials. In similar way as the EYE move some amount of potentials are generated by the neurons these potentials get observed by the optical sensors that are placed around the brain. These potentials are converted into electrical potentials which As we know that the optical mouse mouse works under the principle of snap photos i.e., the optical mouse take's several photos at a time when the mouse is subjected to move and the snaps which are taken by the mouse is transmitted to the system. The C P U receives the data and transfer to the mother board where the operation is executed. In similar way we use the optical sensors and wireless technology to send and receive the data.
