Researchers from the Center for Research and Advanced Studies
(CINVESTAV) in Mexico have developed a pair of glasses that use a
combination of ultrasound, GPS, stereoscopic vision and artificial
intelligence to help the visually impaired to navigate their
environment. The device, perhaps the most sophisticated of its kind, is
slated to reach mass production early next year and will likely cost up
to US$1,500.
Over the past few years we've covered several devices for the blind and visually impaired, ranging from wrist-mounted sonars to guide vests with
helmet-mounted cameras. As electronics keep getting much smaller,
faster and less power-hungry, these devices can now start providing
better guidance to their users, while becoming less intrusive and more
affordable.
Building on previous work in stereoscopic vision algorithms for robots,
a research group headed by Prof. Bayro Corrochano has built what is
perhaps the most advanced system of its kind to date. The device
consists of a pair of glasses with two cameras mounted on the frame, for
effective stereoscopic vision. The glasses work in tandem with a tablet
device that processes the data and then provides audible directions to
the user.
The ultrasound technology embedded in the glasses can detect nearby
static and moving objects, including translucent objects like glass. The
device can also use AI to recognize locations, read signs, and identify
objects such as various banknote denominations and color of clothing.
Finally, included GPS can provide audible directions. The battery lasts
for approximately four hours of continuous use.
Corrochano and colleagues have patented the technology and expect to
have a commercial prototype by August, planning mass production for
early 2015, provided that they find investors. The final product would
cost between $1,000 and $1,500.
