Conventional yoga classes with an instructor up front demonstrating positions to the class aren't generally a viable option for the visually impaired, but a team of computer scientists from the University of Washington (UW) is set to open this healthy activity up to such users with the help of a Microsoft's Kinect.

A new smartphone-based portable eye examination kit called Peek is aiming to bring hope to people suffering from eye problems who live in remote parts of the world. Besides being portable and easy to use, system makes it possible to perform complex eye tests with no need for expensive equipment. Read More
Unfortunately, there aren't many options available for the visually impaired when it comes to timepieces. While a number of talking watches and braille wristwatches with removable covers are already on the market, those often draw attention to a person's disability. That's why watchmaker Eone's debut timepiece, the Bradley, indicates the time with magnetic ball bearings that can be read subtly by touch. Read More
The OrCam is a small camera linked to a very powerful wearable computer. It sees what you see and through your finger-pointing understands what information you seek, relaying auditory feedback through a bone conduction earpiece. Using an intuitive user interface, the device can read text, recognize faces, identify objects and places, locate bus numbers and even monitor traffic lights. Read More
Just like other parts of the body, the retina needs oxygen in order to survive. If it doesn’t receive enough – should its blood supply be restricted, for instance – permanent blindness can result. Therefore, the sooner that doctors know if a patient’s retina is receiving insufficient oxygen, the better the chances that they can take action in time. Soon, they may be able to use tiny injectable robots to get them the information they need. Read More
In the Spider-Man comics and movies, the famous hero's "Spider Sense" warns him of incoming danger, which proves to be just as important a superpower as slinging webs and climbing walls. Now a group of researchers at the University of Illinois in Chicago may have found a way to replicate such superhuman perception that doesn't involve any radioactive spiders. Using a collection of sensors placed all over the body, the group has designed a "SpiderSense" suit that detects objects in the environment and warns the wearer when anything gets too close.

While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).

Second Sight’s Argus II Retinal Prosthesis is definitely an interesting piece of technology, allowing a blind user to “see” objects, colors and movement in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject’s retina. Read More

There could be new hope for people facing vision loss due to conditions such as retinitis pigmentosa or wet age-related macular degeneration. Scientists from the University of Southampton have discovered that easily-gathered corneal cells may be able to take the place of degraded retinal cells, thus preventing or curing blindness.

In an effort to enable blind people to navigate their surroundings more safely and effectively, researchers at Israel’s Weizmann Institute of Science have drawn inspiration from an unexpected source: rat whiskers. Read More
