Eye Writer For The Paralyzed

The software running on the PC tracks the eye movement and a cursor on the PC screen simultaneously moves with it. A virtual keypad is displayed on the screen along with text area similar to android messaging. the cursor is controlled by eye movements. Once the cursor is brought on top of a letter the user has to blink 2 times in succession (user may also click by holding eye on the letter for 1 second). for cancelling the letter typed user may click on the cancel button similarly. Also for sending the user has to move the eye to click on the send button. The eye is tracked using a normal camera mounted on a glass. The tracking is done using JAVA running on a PC.
