Proximity : A virtual cane for the visually impaired

The sense of touch is second only to the vision when in comes to the amount of brain matter dedicated to it. Hence it is a natural recourse for visually impaired individuals to sense their world. In this project we demonstrate a smart wristband, that squeezes the users wrist depending on how close or far the object he points to is from him. It uses an ultrasound range finder and a simple motor to achieve this. With such a werable device, the user can sense the world around him and get a picture of it through pressure. A kind of a “Virtual Cane”

The project was completed in 2011.
