Wearable Technology: Low vision device
The university of Washington is working on a device to help the vision impaired. Using infrared technology, the device is capable of analysing the distance of objects and warn the wearer of the device of a possible collision by projecting an icon onto the their retina. The icon is projected using a vibrating crystal fibre that is attached to a laser diode. The vibration of the fibre creates horizontal lines which give the viewer the illusion of a translucent image.
At the moment the prototype is still fairly large and bulky, and needs to be carried around in a backpack, weighing around 10 pounds. Apart from reducing the size and weight of the device the team could also be looking into using laser light to stimulate the optical nerve in the eye directly, so that people whose eyes’ photoreceptors don’t work could see again.
Myth or Fact? Technology or a bit of plastic with a fancy description? 
Tired of having to retie your shoe laces after they have come undone? Are you uncomfortable running because you haven’t tied the laces evenly and now they are too tight in one spot and too loose in another spot?
