HAND GESTURE BASED WHEEL CHAIR
MOVEMENT CONTROL FOR THE DISABLE USING (MEMS TECHNOLOGY)
ABSTRACT:
The use of powered
wheelchairs with high navigational intelligence is one of the great steps
towards the integration of severely physically disabled and mentally
handicapped people. Driving a wheelchair in domestic environments is a
difficult task even for a normal person and becomes even more difficult for
people with arms or hands impairments. Tetra pelagic people are completely
unable to operate a joystick unless they use the tongue, which is obviously a
very tedious task. Simultaneously blind and paraplegic people deal with a very
uneasy situation which couples two problems: locomotion and localization. The
Rob Chair system is being developed to overcome the problems described above,
allowing the end-user to just perform safe movements and accomplish some daily
life important tasks.
3 Axis
Acceleration Sensor Board based on ADXL3XX from Analog devices is used for
gesture recognition. It is a first generation 3 axis acceleration sensor. User
could get acceleration value of X, Y, and Z axis. And it is widely used in
shock, slope, and moving detection. Output sensitivity could be select by
simply set voltage level on few pins. The output of the sensor is analog mode.
A
prototype chair is implemented with a small chair and 60rpm motors are used to
move the chair. A free-wheel is arranged to change the chair direction
according to user’s requirement.
This
project uses 12V rechargeable battery. This project is very much useful for the
disabled.
