Infrared based Mouse control

This project moves and clicks a mouse cursor on a computer screen by tracking where the user’s eye-movements using infrared eye-tracking technology and a gyroscope. It can be useful for people with physical disabilities and provide them with a way to control the monitor. Instead of using a camera they are using a combination of LED’s and phototransistors which have reduced the cost of the project by a huge margin. The LED’s used are mounted on a custom made spectacles like think, which doesn’t restrain user from making any movement and hence giving this device an edge over other products presently available.

All of these glasses-mounted components namely the LED system along with the gyroscope are connected to a microcontroller, which parses the LED and gyroscope data into USART packets and transmits it wirelessly. The packets are read by a wireless receiver on a separate ATMega1284P board, which moves the mouse cursor using a Java program based on the information received. The LED’s used are low power LED’s which also doesn’t damage the user eye. You can read more about this project on the project website.
