Abstract

Development of automatic voice activated low cost wheelchair using intelligent standalone controlling system and Interfaces (Embedded LabVIEW and Compact Reconfigurable Input/Output FPGA Card-cRIO-9074) for physically impaired people is presented in this paper. Various interfaces to control the powered wheelchair were proposed in the past since the voice is the most natural communication ways for person so our study pays more attention to speech recognition. The voice commands produced by the user are captured and processed by the intelligent system. The system is integrated with Ultrasonic sensor and IR sensor for obstacle detection and path finding.
