Voice and Gesture Based Electric-Powered Wheelchair Using ARM
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2012, Vol 1, Issue 6
Abstract
A voice and gesture based system has been developed to control a wheelchair using voice commands and moment of hand i.e. Mems sensor is connected to hand. The system is divided into two main components: speech recognition module with Mems sensor and wheelchair control unit. In the speech recognition module, hidden Markov models are used as the main method in recognizing voice commands. The Mems sensor senses the angle of the hand, i.e. according to the tilt of hand it gives voltages to microcontroller. The wheelchair control unit is developed using ARM controller.
