Smart Walking Aide for People with Limited Peripheral Vision
http://www.medgadget.com/wp-content/uploads/2015/03/eye-ear.jpg
Smart walking sticks and body worn sensors that detect*nearby objects have been tried in the past to help visually impaired people avoid hitting obstacles. Yet, the tech**logy tended to be more an**ying than helpful, beeping anytime anything was near. A truly smart proximity sensor should instead predict a chance of hitting an object rather than just being told that something is near.*Researchers from Massachusetts Eye and Ear, Schepens Eye Research Institute have developed a body worn device that can do just that.
The prototype system has a wide angle camera on the front that tracks objects in proximity. It actually predicts potential collisions, beeping when there’s a good chance the wearer might strike something. They tested the system with tunnel vision and hemia**pia volunteers walking through a 41 meter-long course with 46 objects throughout, each as tall as the participants. The study showed that folks wearing the device had a reduction in collisions with objects by 37% compared to*when **t using a walking aide.
Here’s a demo of the latest prototype:
Here’s a head-worn prototype of the device in action:
