Belt Warns Visually Impaired about Obstacles
For years cars have had warning systems to let drivers know when they're about
to back into something. What if a similar type of obstacle avoidance technology
could be used to help the visually impaired?
That's what two University of Pennsylvania researchers are trying to develop.
They've created a prototype warning system for walkers called Kinecthesia. It's
a belt loaded with the following: a Microsoft Kinect infrared camera and
sensors, battery pack and six vibration motors placed in the left, right and
middle of the belt.
When worn the Kinect detects obstacles in your path. If the obstacle is to your
left, the motors on the left side of the belt will vibrate. As you get closer
to the object the vibrations get stronger.
The researchers want to make the belt as small and affordable as possible so
that they can better serve the 285 million visually impaired people around the
world. The technology might also be useful for firefighters, miners and anyone
else working in low visibility areas in need of some good vibrations.
