The risk of colliding into objects and hurting herself has always been an issue, every time T. Jayaseeli, a postgraduate student, steps out.
Her regular white cane doesn’t really help with objects that are above knee-level, says the visually-impaired student. “It’s also hard to know when a moving vehicle is about to cross your path,” she says.
To help with this and minimise chances of injury, Indian Institute of Technology (IIT)–Delhi, in association with Phoenix Medical Systems and Saksham Trust, has come up with a solution: a smart cane. It uses ultrasonic ranging to detect objects up to three metres away and generate a vibrating signal the user can feel.
The cane is foldable, ergonomic and uses a detachable device attached to the regular white cane. It can sense objects as narrow as 3 cm and has an in-built rechargeable battery that can last eight hours on full charge. It also emits a long beep when a fast-moving object crosses the user’s path.
However, it requires some simple orientation and training to be used.
