Wireless intellichair is designed to help the paralysed person who moves on a wheel chair, instead of the handicapped person moves the wheel chair by his hand, the chair will automatically move to a particular direction as the patient moves his eyes towards a direction, with the help of Eye ball movement detection sensor. The chair will also sense the obstacles in front of it and gives a beep sound.
The numbers of persons who are paralyzed dependent on others due to loss of self-mobility is growing as the population ages. We have developed a wheelchair prototype exclusively controlled by eye and able to be used different users while proving robust against vibration, illumination change, and user movement. The keys to this ﬂexibility are the camera mounted on the user’s glasses and the use of pupil detection. Image processing analyzes the user’s gaze for wheelchair control.
AVR Microcontroller Board
This is the board which contains AVR Microcontroller Chip as well as the clock Circuitry, Reset Circuit and Power Supply for the Microcontroller.
Provides Power Supply for the IC’s and components
An Infrared sensor is used as a intruder detector. So when an intruder is sensed we can redirect the movement of the Model.
This is used to sense the movement of the eye ball’s direction and converts it into digital data and transfers it to the Master controller. (Straight Command, Left/Right Command, Stop Command)
AVRs are generally classified into following:
