Electronic travel aid that helps the blind identify obstacles

The SmartCane is an electronic travel aid that improves upon the regular white cane used by the visually impaired.

The device fits on the top fold of the white cane and helps to detect obstacles that are above the knee or are hanging like the side of a truck, hanging cloth strings, coolers or air conditioners that are jutting out, railings, tree branches, inclined ladders, etc.

These obstacles can result in injury to the head or upper body parts and need to be detected early.

The cane can also detect the presence or absence of objects in the surroundings.

The aid has been developed by IIT Delhi and costs Rs 3000.
