Smart phone based wheelchair navigation and home automation for disabled

摘要

Mobility-assistive device such as powered wheelchair is very useful for disabled people, to gain some physical independence. The three main functions of the proposed system are, 1) wheelchair navigation using multiple input, 2) obstacle detection using IR sensors, 3) home automation for disable person. Wheelchair can be navigated through i)voice command or ii) moving head or hand in four fixed position which is captured using accelerometer sensor built in android phone. Using 4 IR sensors we can avoid the risk of collision and injury and can maintain some safer distance from the objects. Disable person cannot stand up and switch on-off the light or fan every time. So to give them more relaxation this system offers home automation by giving voice command to the android phone or by manually swipe the button on the screen. The system can be available at very low cost so that more number of disable persons can get benefits.
