ARM 7 based voice controlled wheelchair and patient monitoring system using GSM

This paper describes about the controlling of wheelchair by means of human voice and patient monitoring using GSM. In earlier, people use joysticks to control the powered wheelchairs. Wheelchairs with the standard joystick interface are unable to control by many people. Speech recognition is a prominent technology which can give an alternative, people to interact with machines especially those who are quadriplegics. We have resolved the disabled problems by implementing voice control interfacing, over a microphone for the wheelchair. The powered wheelchair depends on the motor control and drive system which consists of ARM Processor and DC Motor. In addition with the wheelchair the patient monitoring system (pressure, heart beat, and temperature) is provided. The abnormal conditions are intimated by sending message using GSM Technology and also the system detects the opposite object using ultrasonic sensor.
