Sure, we've seen brain power used to give mobility back to the immobile, but a new development in Europe is one-upping current efforts by adding in a hint of artificial intelligence to the tried and true brain-computer interface. The MAIA BCI not only converts signals emitted by the brain into actions -- such moving a wheelchair forward -- it also thinks for itself when needed in order to assist the user in getting where he / she wants to go. Essentially, the individual need only think about going left or forward (for example), and the machine itself will automatically detect obstacles and potential barriers in order to move more efficiently. As it stands, there's still quite a bit of testing to be done before MAIA-based wheelchairs would be available to the public, but researchers are already hoping to integrate said technology into artificial limbs and the like.
Yeah, we've got HMDs for the visually impaired, but seriously, who's for sporting one of those things just to catch an afternoon soap? Thankfully, Dr. Eli Peli (and colleagues) from Harvard Medical School is lookin' out for said sect, and has developed a method for "enhancing the contrast of images of people and objects of interest on their digital televisions," which, during trials, was found to enhance legibility and overall enjoyment when watching. Furthermore, the technology is said to be the first to play nice with digital TV images, which seems fairly important considering that analog signals have but a few months to live here in America. Purportedly, the all-important modification that made the adjustments possible could be applied to HDTVs and digital STBs in the future, and sure enough, Peli has already sparked up conversation with Analog Devices in order to create a prototype chip for use in forthcoming sets. Now, if only clearing up those Get Smart reruns were this simple...
We've seen a smorgasbord of off the wall creations designed to help those with limited motor skills interact with the average PC, but a group of Kent State researchers have returned to square one and devised a more useful method of actually getting the computer turned on in the first place. The team, which including a graduate assistant who has quadriplegia, found the solution by "adding a jack to the back interior wall of the tower and paralleling it to the on / off circuit of the motherboard." Subsequently, any number of sip / puff switches (pictured device is for reference) could be attached to the jack in order to power the machine on without the use of one's hands or feet. Sadly, there was no mention of bringing such a useful creation to market, but with the right handyman, we're sure this project wouldn't be too hard to replicate on your own.
Early last year, gurus at the University of Michigan were devising a newfangled type of cochlear implant, but now it looks like the Wolverines are more interested in a fresh auditory nerve implant that is being dubbed "a superior alternative" to the (now) old fashioned option. The uber-thin electrode array would purportedly "transmit a wide range of sounds to the brain," and could give profoundly and severely deaf people the ability to "to hear low-pitched sounds common in speech, converse in a noisy room, identify high and low voices, and appreciate music." Researchers on the project are convinced that this technology trumps cochlear implants in every way, and while preliminary patents have already been filed, it'll still be nearly a decade at best before these things can invade human ears en masse.
Although we've seen gait monitors and even prosthetic feet that assist individuals in regaining a more natural stride, scientists at Technion Institute of Technology in Israel have resorted to a head-mounted display for its rendition. This virtual reality device combines "auditory and visual feedback to improve walking speed and stride length in patients suffering from Multiple Sclerosis and Parkinson's disease," and provides the wearer with a "tiled-floor image" that apparently assists them in navigating nearly any terrain. The device is meant to take the place of normal muscle feedback mechanisms, and to provide said feedback to these disabled individuals so they can make adjustments and improve the efficiency of their walk. The HMD has already made its way to several medical centers and has purportedly yielded positive results, but there was no word on when this device would be commercially available.
After a solid four-mile run on the Doggy Treadmill, it's not too tough to understand why Fido is famished, but for folks who are disabled in ways that make bending down or moving around in general difficult, getting the pet food from the pantry to the bowl has been a serious chore. Thanks to a retired engineer (who was stricken by cerebral palsy) that figured he better solve his own problem rather than wait for someone else, the DinnerUp apparatus was concocted, and now it's on the brink of commercialization. The device mounts onto a kitchen counter or door and relies on a hand crank / clutching system in order to lift the attached bowls to a level that's easy to reach, after which it's lowered back down to the anxious pets below. Currently, Ray Dinham is assembling the units himself and offloading them to "satisfied customers" for £70 ($140) apiece, but it shouldn't be long before the manufacturing is "outsourced to a UK-based firm" and these gain some serious worldwide traction.
In an attempt to create a more fashionable alternative to the wheelchair devices that handicapped children currently rely on to get around, a group of engineers at the Bath Institute for Medical Engineering, in consultation with parents and occupational therapists, have concocted the car-like Whizzybug. The all-terrain vehicle can reportedly handle asphalt and green pastures without issue, and sports a blistering top speed of two miles-per-hour. Additionally, it can be controlled by the caregiver or the youngster, weighs in at just under 70-pounds, has a "fully adjustable seating system with memory foam cushions and a programmable joystick," and to top things off, this bad boy even touts a trailer hitch for towing those weak Power Wheels rigs out of the rough. The devices are slated to be sold by the developing charity, Whizz-Kidz, "at cost," which means that interested parents will be looking at anywhere between £1,700 ($3,406) and £2,000 ($4,007) depending on options.
