The basic idea of the projects is to build a human machine interface which can be used to control mouse using head-tilt and eye-blink. This mouse-emulating device can be found to be most useful by physically handicapped people who can no longer control the computers using their hands. Since the device relies on user s head and eye movement, it can be used even by patient who are paralyzed from shoulder downward. Simple head movement doesn t require too much energy and neither does eye blinking. Therefore user won t get tired from using this device. In this device or goggle we are using 2D-acce...
The basic idea of the projects is to build a human machine interface which can be used to control mouse using head-tilt and eye-blink. This mouse-emulating device can be found to be most useful by physically handicapped people who can no longer control the computers using their hands. Since the device relies on user s head and eye movement, it can be used even by patient who are paralyzed from shoulder downward. Simple head movement doesn t require too much energy and neither does eye blinking. Therefore user won t get tired from using this device. In this device or goggle we are using 2D-accelerometer for detecting the movement of the head according to this, the movement of the cursor has been done. A photo sensor detects eye blinking. The Infrared transceiver consists of a 935nm IR transmitter and a phototransistor mounted on the same unit. This detects a strong increase in the reflected signal upon intentional long blink as compared to normal eye blink.
