Hybrid wheelchair controller for handicapped and quadriplegic patients In this dissertation a hybrid wheelchair controller for handicapped and quadriplegic patient is proposed. The system has two sub controllers which are the voice controller and the head tilt controller. The system aims to help quadriplegic handicapped elderly and paralyzed patients to control a robotic wheelchair using voice commands and head movements instead of a traditional joystick controller. The multi input design makes the system more flexible to adapt to the available body signals. The low cost design is taken into consideration as it allows more patients to use this system.<eng>
