MULTIMOD AL INTERFACE FOR DISABLED PERSONS

This paper presents a technique of how Eye, Hand Gestures or voice command can be used to control the movement of wheelchair. For Hand gestures we present a scheme which reduces the size of the database which is used to store different postures of human beings which are used by robot as commands. The picture frame may divide into different scan lines and pixel color value under these scan lines are examined to guess the particular posture of user. The robot may use this as command and act accordingly. For interfacing through eye a new algorithm for tracking the movement of eye towards left or right is also proposed. The eye blinking feature can also be used by the algorithm to control the starting and stopping of wheelchair.
