SUMMER WORKSHOP ON DESIGN AND INCLUSIVE INNOVATION

OBSTACLE DETECTION DEVICE FOR VISUALLY IMPAIRED WHEEL CHAIR USERS


Introduction
According to the WHO about 285 million people worldwide are visually impaired of which approximately one in ten blind persons use a wheel chair. This kind of disability is caused majorly due to accidents and health related problems like diabetes, multiple sclerosis and stroke. The kind of people faces lots of problems like loss of mobility, spontaneity, flexibility and low self confidence to mention a few. Majority of the work has been done in the field of either visually impairment or the persons with locomotive disorders but there is very little assistance for people with multi- disability. These people have special needs and a different approach is needed to address their problems. Thus our team decided to do something for this section of the society.


Proposed Solution

We are proposing a detachable device which can be attached to the existing wheel chair. If any user using a wheel chair along with the device approaches the obstacle, the sensor will detect the same and provide tactile feedback to the user to warn him about the obstacle. We will try to identify the direction in which the obstacle is present by using a combination of sensors, so that the user can correct his/her path suitably.
