“GESTURE BASED WHEEL CHAIRS FOR PHYSICALLY DISABELD PERSONS”

The needs of many individuals with disabilities can be satisfied with traditional manual or powered wheelchairs. A segment of the disabled community finds it difficult or impossible to use wheelchairs. There is extensive research on computer - controlled cha irs where sensors and intelligent control algorithms have been used to minimize the level of human intervention. This project describes a wheelchair for physically disabled people. Our goal is to design and develop a system that allows the user to robust ly interact with the wheelchair at different levels of the control and sensing. A dependent - user recognition using hand movements and infrared sensor integrated with wheelchair. Automatic wheelchair basically works on the principle of acceleration, one a cceleration sensor, provides two axis, acceleration sensors whose output varies according to acceleration applied to it. Sensor gives x - axis & y - axis o/p independently which is fed to Comparator & then μC. On chair Obstacle sensors will be installed for de tection of wall/obstacle in the backward direction
