According to the BBC, Researchers at the University of Southern California have developed a “bionic eye” and will begin doing clinical trials to test the device. A camera is mounted on glasses and sends an image to electrodes implanted in the retina, stimulating the damaged cells in the eye.
What we are trying to do is take real-time images from a camera and convert them into tiny electrical pulses that would jump-start the otherwise blind eye and allow patients to see,” said Professor Mark Humayun, from the University of Southern California.
At the moment, the implants produce only rudimentary vision. According to The Washington Post, six patients have used the implants to “distinguish light, perceive motion, and identify general shapes and objects.”
The trials are expected to take two years, after which the BBC reports that the devices are expected to become available to individuals at a cost of approximately $30,000 USD. The targeted diseases are retinitis pigmentosa or macular degeneration, which cause the death of retinal cells; according to the Washington Post, the new study will focus on patients over 50 years of age.
Last September at Tokyo’s Home Care and Rehabilitation Exhibition in, Matsushita Electrical Industries showed a robotic jacket which lets a partially paralyzed limb move in response to cues from the undamaged arm.
An artist named Shusaku Arakawa and his partner have designed a fantastical condo development in Mitaka, Japan. Called “Reversible Destiny,” it’s meant to challenge the occupants. The exterior is brightly colored, with improbable lines and edges running helter-skelter over the facade, and strangely shaped windows and openings.
They’re not cheap, but wah-hoo, are they fun! Is your wheelchair looking ho-hum? Does someone you love need a really original gift? 
Don’t let the home page scare you — the rest of the site’s much better designed. It’s also friendly, but a little amateurish — and there’s no indication of shipping costs. You might want to email or call before making a commitment.
I haven’t seen this in person yet, so I’m throwing it out for the ‘may be worth investigating’ file. The Wijit is a set of geared handles attached to manual wheelchair wheels. The idea is to allow cleaner (literally) and more ergonomic propulsion of the chair — no more grabbing for wheel rims with the attendant stress on the back and shoulders.
Several years ago my in-laws needed a simple remote control for my husband’s grandmother. I told them about this one, which has just six buttons — the power button, a mute button, and the four critical ones: channel up, channel down, volume up and volume down. The large buttons, and the simplicity of the thing made it a logical choice. It runs about fifteen dollars. 
was falling like crazy though — sometimes managing to bruise both of us in the process — very unstable, and short on stamina. Just getting him into and out of a car was adventure enough — we were really in trouble when we finally got to the doctor’s office, and going much of anywhere else just didn’t work well.
