10. ANDROID APPLICATION

Engineering developments offer opportunities to develop smart wheelchair assistive technology like various modules and certain add-ons that can improve the lives of many people who use wheelchairs.

The students of computer science engineering proposed to develop the technology for a smart wheelchair and interface it with a controlling module. This technology is appropriate for people who have lost mobility due to brain injury or the loss of limbs, but who retain rational thinking. The technology is used to enhance safety for users who can now use ordinary movement powered wheelchairs to prevent collisions with walls, fixed objects, furniture and other people. The efforts are inspired and motivated by the insights, feedback, and needs of the patients who depend on hospital staff and family members for their constant help.

This part of the project deals with the designing of the technology behind the control of these intelligent wheelchairs. The goal of this smart wheelchair project is to enhance an ordinary powered wheelchair with navigation keys for the self-mobility, authenticated access of one’s own medical records from the connected hospital’s database and to obtain help during emergencies. This technology is appropriate for people who have lost mobility due to brain injury or the loss of limbs, but who retain rational thinking. The technology is used to enhance safety for users who can now use ordinary movement powered wheelchairs to prevent collisions with walls, fixed objects, furniture and other people.

Strategies would be developed to accomplish newly-identified goals which may involve additional sensors, computing and interfaces.
