PRINCIPLE OF EYEBALL SENSING

The basic principle of this direction sensing is the colour of the eyes.

There are two main colour pigments in the human eyes. i.e., black and white.

Challenges

Start-stop challenge

Safety challenge

Universal gadget Challenge

Start-Stop Challenge

Question is, how to start and stop the wheelchair if the person is unable to use his hands or voice for the purpose?

The only option is to set certain eye gestures that will act as a signal for the micro-controller to start and stop the wheelchair.

Safety ChallengeThe wheel chair should be accident free

Cases of accidents:• Unconcious rider• Collision

Solutions:

Closed eyes detection

Collision detection

‘Unwanted Movement’ Challenge

Wheelchair should not move or navigate itself without the driver wanting it to do so.

Wandering gaze or rather wandering eyes prove to be a challenge

Wheelchair should halt if the driver falls asleep or unconcious (discussed in safety challenge)

Universal Gadget ChallengeEvery eye should be able to use the gadget comfortablyHence adjustable positioning is required

Conclusion:The project is aimed towards developing a usable, low-cost, assistive robotic wheelchair system for disabled people.

We present a system that can be used as a means of control allowin the handicapped especially those with only eye-motor co-ordination, to live more independent lives.

This project is applicable to all disabled, since eye movements require minimum effort and is a pre-requisite for all drivers.
