MIT Developing Wheelchair That Listens When You Speak


Oh MIT, do the wonders that come from your halls ever cease? Yet another remarkable development is emerging from the fabled institution, and this time it's an autonomous wheelchair that can remember important places in a given building (read: the hospital ward, your house, the local arcade, etc.) and then take you there on command.

In other words, the voice recognizing chair could understand phrases of direction, such as "head to the kitchen," and it would take on the burden of navigating the halls while letting the rider chill. The researchers are implementing a system that can learn and adapt to the individual user, and in the future, they'd like to add in a collision-avoidance system and mechanical arms to help patients lift and move objects.

Say, can regular joes / janes buy these? We're totally feeling this over the Segway.

ReWalk Exoskeleton Helps Paraplegics Walk (Video)


ARGO Medical Technologies' ReWalk has been out a few months now, but it's tough to really appreciate what this thing can do unless you see a patient utilize one on video. Hailed as a "quasi-robotic ambulation system," the wearable device was specifically created to assist those with lower-limb disabilities and give them back upright mobility.

In the video waiting in the read link, one particular individual relies on the ReWalk to stand up and move about after being stricken to a wheelchair for 20 years -- no need to take our word for it, though, real live proof is but a click away. [Source: Israel21c Via MedGadget]

Web App Brings the Internet to the Blind


The Internet is supposed to be the great equalizer. Race, color, creed, class, and physical handicap are supposed to of no impediment on the Web. Unfortunately, the blind face great obstacles in getting online, especially from public computers, like those in a library or Internet cafe. Screen reading software is rarely installed on these PCs, and portable options are often prohibitively expensive.

A new Web app from a graduate student at the University of Washington aims to help break down these barriers by bringing screen reading technology to any Web-connected computer. If the user can navigate, or have someone navigate, to http://Webanywhere.cs.washington.edu/ they'll be able to launch an in-browser screen reader. The reader, called Web Anywhere, will work on any computer with any modern Web browser, such as Firefox or Internet Explorer 7.

The reader is still in early development and needs some tweaking, but it looks to be a potentially revolutionary tool for the blind. You can check out the video above for a demonstration of how the Web app works. It's nice to see someone using the powerful tools made available via the Web to build something that does more than let you share photos and 'poke' friends. [Source: Yahoo! News]

Researchers Devise Neural Implant That Learns Over Time


Brain-machine interfaces have done quite a bit in helping handicapped individuals interact with prosthetic limbs, computers and other humans, but a new neural implant concocted at the University of Florida could make all those past devices look archaic.

Put simply, researchers have discovered a method that would enable brain-machine interfaces to "adapt to a person's behavior over time and use the knowledge to help complete a task more efficiently." Until now, the brain was the instrument doing all the talking while the computer simply accepted commands; with this method, "the computer could have a say in that conversation, too."

In all seriousness, this type of learning mechanism could be game-changing in the world of physical therapy, but we hesitate to give something mechanical inside of our body too much free will, ya dig? [Source: University of Florida News via Physorg]

A Wheelchair Powered By the Mind


(Note: The above video is a bit slow to load ... )

Michael Callahan and Thomas Coleman want to put the minds of the handicapped to work. The founders of the Champaign, Illinois-based firm Ambient have invented a wheelchair powered by the mind -- and, fortunately, you don't need Uri Geller-grade brain muscles to get the wheels spinning.

The Audeo motorized wheelchair works by having the occupant mentally choose word commands for moving forward, back, left and right. When a human being thinks of a word, the brain shoots a signal to the larynx in order to produce speech. The Audeo intercepts these neural signals and translates them into commands for the chair. Unlike the wheelchairs of today, the Audeo will allow a person who is completely physically incapacitated to move themselves around unassisted. And, movement may just be the beginning as this technology could someday allow us humans -- handicapped or not -- to control all sorts of devices with our minds. The only prerequisite would be the ability to think. Sorry, Britney.

Control an iPod with Your Teeth!

Control an iPod with Your Teeth!

Researchers at Japan's Osaka University have developed a technology that is sure to be a boon to the handicapped and terminally lazy: a headset rigged with a small computer and infrared sensors that detect when the wearer clenches his teeth. These mouth movements are then translated by the headset into commands for controlling MP3 players and other devices -- a technology that could potentially allow a paralyzed person to place cell phone calls or dial 911 in an emergency without assistance.

But, wait a minute, hasn't disabled super scientist Stephen Hawking been using a contraption like this for years now? Actually, Hawking, whose body is deteriorating as a result of Motor Neuron disease, uses a system that tracks his blinking. Attached to his glasses is a device that emits a low-powered infrared beam. When Hawking blinks, his cheek muscle changes the reflection of the beam ever so slightly, which is interpreted as computer commands.

While the system Hawking uses is made to specifically interact with devices that aid the handicapped, the Japanese team intends to first market its product for casual use with lazy iPods owners, and then someday maybe adapt it to wheel chairs.

So, goodbye chewing gum, right? Well, according to the researchers, the headset's software is able to differentiate between normal chewing and the overtly intentional clenches meant to control the device ... though there's no word yet if that claim has passed the mouthful of peanut butter test.
