Implementation of Smart Wheelchair using Ultrasonic Sensors and Labview

The implemented patient-monitoring smart-wheelchair system is an ambulatory aid for specially-abled people along with continuous monitoring of the user’s vital body parameters. In order to take into account different disabilities, four interfaces have been developed for wheelchair control namely eyeball control, gesture control, joystick control and voice control. A camera is used to capture the image of the eyeball. LabVIEW is used to take necessary decision depending upon the position of the eyeball. Remaining three modes also provide control over the wheelchair movement. Ultrasonic sensors are employed for implementing anti-collision mechanism. In the wheelchair body temperature and heart rate monitoring provision is made. This system will alert proper medical authorities and the wheelchair user’s selected individuals if any parameter is out of safe range. The final project is an assistive technology with a difference which would make the life of its user easy and more stress free.
