Hokies give (tactile) sight to the blind so they can drive, no word on turning water into wine
Daytona International Speedway is synonymous with speed, auto racing, and . . . blind people? Virginia Tech's Robotics and Mechanisms Laboratory (RoMeLa), along with the National Federation of the Blind (NFB), recently debuted its sight-optional and street-legal SUV at the famed racetrack. Dr. Dennis Hong and his students first let blind folks drive a dune buggy without the help of a sighted copilot in 2009 -- as a first step to achieving the goal of a street-legal SUV for the sightless crowd. The SUV in question was designed for the NFB's Blind Driver Challenge, and is equipped with a drive-by-wire system -- also seen in the RoMeLa autonomous vehicle -- that was modified for use with RoMeLa's SpeedStrip and DriveGrip tactile interface technology. It works by using a laser rangefinder to map the surrounding area, relaying information for acceleration and braking to the driver by rumbling the SpeedStrip seat, and passing along turning info through vibrations in the DriveGrip gloves. The system was not developed solely for the purpose of getting blind drivers on the road, however, as Virginia Tech suggests that its technology could also be used in gaming applications. We're not quite ready to see blind drivers on actual roads just yet, but why shouldn't our sight-impaired friends get to enjoy Gran Turismo 5 with the rest of us? Video's after the break.
Thimble concept translates real-world input into real-time Braille (video)
From the great tomorrowland of concept videos comes yet another potentially life-changing product: a thimble (looks more like a one-finger glove to us) that takes ambient input and relays it in via an electro-tactile grid to the wearer's finger in Braille. It gets text input from an embedded camera, like in the picture above, or pulls RSS feeds, books, or presumably any other text via a Bluetooth-paired smartphone. We are, of course, addicted to the flow of info our mobile devices feed us throughout the day, and this little guy seems like the perfect tool to bring that flow more easily to the visually impaired. Now, venture capitalists, work your magic -- we'll be expecting to see this thing on shelves just in time for holidays season 2012. Video after the jump.
Braille Buddy concept keyboard teaches six-dot typing
We've seen any number of gadgets designed to help the visually impaired read (and even occasionally drive), but it's not all that often peripherals come along that teach Braille in the first place. Yasaman Sheri's Braille Buddy concept is clearly the exception to that rule -- it's a six-key device that unfolds like a pearly-white Batarang and audibly speaks letters to you. Would-be learners can then feel the six-dot formation of each corresponding Braille character on the electroactive polymer screen up top, then key in the newly-learned unit of writing with the six buttons on the swinging handles below. A description at Yanko Design suggests Sheri is serious about making these available at libraries and schools, where they'll hopefully spend more time generating text than sailing through the air. Spot the device unfolded right after the break.
Prototype car with tactile feedback challenges the blind to drive (update)
We can already imagine just what you're thinking -- the blind have no place behind the wheel, right? As it turns out, though, cars can steer themselves these days, so there technically no reason why (save a few laws) a computer-assisted blind person couldn't drive. Virginia Tech's RoMeLa successfully tested a laser-guided dirt buggy last year (see above), and teaming with the National Federation of the Blind this week, it intends to demonstrate a pair of full-sized augmented SUVs next year. In January 2011, the Daytona racetrack will play host to two heavily customized Ford Escape, filled with "nonvisual interfaces" like a vibrating vest and gloves (dubbed DriveGrip), a steering wheel that provides audio cues on when to turn, and a tablet device covered with tiny holes (called AirPix) that represents the road and obstacles around the vehicle with jets of compressed air. Even with all those gizmos, we understand if you still might not want your neighbors barreling down the street, but let's face it -- plenty of us sighted folks are just as visually impaired. Video and full press release after the break. Update: Dr. Dennis Hong of RoMeLa just informed us that though the auditory steering wheel was part of the laser-guided buggy, it won't appear on the Ford Escape. He also relates that letting the blind drive is merely a short-term goal -- the big picture here is to develop new interfaces for the blind, and safer transportation technology for all.
Chevrolet Volt gets driver-activated warning system for the blind
Whether it's voluntary or enforced, it seems to be a safe bet that most electric vehicles will eventually break their silence in one way or another to warn nearby pedestrians -- especially the blind. Chevrolet looks to be taking a slightly different approach than most with the Volt, however, and it recently tested out its system with a group of visually-impaired folks at its Milford Proving Grounds. Rather than simply making the vehicle sound like a regular car, Chevy has implemented a driver-activated system that emits what's described as more of an "excuse me" sound than "hey you" sound whenever you want to warn people you're approaching. Of course, depending on the driver does have its limitations, and Chevy says that future iterations of the Volt are likely to incorporate a more active system that can automatically alert pedestrians. Check it out in action after the break.
In Japan, nerds control girls with joysticks
For some of you, like this guy (look at his face!), this is a dream come true, no questions asked. The rest will be wondering what the hell is going on here. See, that bicycle helmet affixed with what looks like a robotic crab is a not so subtle, ear tugging navigational device that could ultimately benefit the sight-impaired or anyone, really -- it pulls on the left ear to direct the wearer to the left, on the right to go right. Simple. Granted, it looks ridiculous now, but imagine it miniaturized under a tin-foil helmet and communicating with a hands- and eyes-free GPS navigational system. You've just seen the future, how does it feel? %Gallery-76350%
MIT students develop new 6dot braille labelmaker prototype
A group of students at MIT have just unveiled a new prototype of a braille labelmaker / printer, the 6dot. Though not the first, the MIT group's model is apparently more advanced, easier to use, and cheaper than currently available models. Designed with the blind and visually impaired in mind, the labelmaker features an around the neck strap, and six buttons (for each of the dots of a braille character), allowing quick production of accurate labels, including contractions. The internal processor of the device can store up to 16 characters, and "prints" the characters onto adhesive label paper, which the user can then affix for easy identification of household items, such as medications, canned goods, and so on. Though it's still in prototype phase, it's possible the device could cost as little as $200 when it does hit the market. [Via Coolest Gadgets]
New talking TV technology assists the visually impaired
It is easy to forget that just because you can't see very well doesn't mean you don't want to watch TV -- or at least listen. So for those in the need, Ocean Blue Software and the charity RNIB are going to bring a "talking TV" to the market later this year. The long and the short of it is that in the age of on-screen program guides and DVRs, that just being able to find the channel and volume buttons on the remote isn't enough, so to make things easier this new technology will give voice feedback for on screen menus and guide data. Personally we'd also suggest a big TV and maybe a STB with a great zoom feature -- but then again, we'd always suggest the biggest TV you can't afford, so perhaps that goes without saying.
The Mac-cessability Network: resources for Apple accessibility
Touting another blog or website isn't an everyday occurrence here at TUAW, but a recent press release got our notice. A site called The Mac-cessibility Network is the work of six dedicated individiduals, all of whom are visually impaired, who provide the Apple community with a source of information on accessibility. Through updated news, the Mac-cessibility Round Table Podcast, and a list of other sites and resources, The Mac-cessibility Network delivers a single source for information for blind and visually impaired Apple fans, as well as providing other useful facts for other disability groups. One item that I was totally unaware of until I visited The Mac-cessibility Network is that our favorite smartphone, the Apple iPhone 3GS, is also the most useful smartphone for visually impaired people. Why? Going to Settings > General > Accessibility allows you to turn on VoiceOver, which was previously limited to only running on Macs and the iPod shuffle. VoiceOver on the 3GS is amazing, reading your email, helping you to type replies by announcing the keys that are being touched, and otherwise telling you what you're currently touching on the phone. Hints like this, as well as the other resources on this site, make The Mac-cessibility Network a "must-bookmark" site for the visually impaired and for Apple consultants and resellers. Consider making a donation to support the continued viability of The Mac-cessibility Network.
Silicon iPhone case aids the visually impaired
The Invisual iPhone case by Critica is unique, having been designed for the blind and visually impaired. It encloses the entire device and features bas-relief buttons that coincide with a modified home page (you'll have to shuffle some icons around first). The coolest thing is that Critica claims it doesn't interfere with the screen's touch sensitivity or performance at all. The high contrast when the backlight is engaged will benefit the visually impaired.It's just a prototype right now, so no release or pricing information is available. Critica has also stated that a forthcoming application will contribute to its functionality. If we hear any more about this unique case, we'll let you know.Back in April, AT&T announced the Text Accessibility Plan's (TAP) for iPhone and iPhone 3G, which was designed for deaf users as well as those who are hard of hearing.[Via Apartment Therapy]
Silicone Touch: an iPhone case for the visually impaired
The iPhone has never seemed a likely contender as a smart phone for the blind (it's certainly not designed for touch typing), which makes this case by designer Bruno Fosi all the more impressive. The Silicone Touch covers the phone's screen and features a selection of bas-relief buttons that correspond to menu items in a custom app, allowing those with diminished sight access to all the phone's functions, including multi-touch and finger flick scrolling. Right now it's just a concept, but we're hoping to see this one become a reality sooner rather than later.[Via Yanko Design]

Touch Sight camera for the blind displays photos using Braille
Gadgets for the visually impaired are nothing new, but the Touch Sight camera is one of the most unique we've seen. Designed to be held against the forehead, the camera doesn't have an LCD, but instead displays a three-dimensional representation of the image on a built-in Braille screen and records three seconds of audio to assist users in locating and managing shots. Just a concept for now, but let's hope it makes it to market -- it seems like it'd be a fun toy for the sighted as well.
Tactile Wand concept aims to aid the visually impaired
We've seen plenty of gadgets designed to aid the visually impaired, but none quite like this so-called "Tactile Wand" concept from designer Jin Woo Han, who's no stranger to nifty concept devices. Obviously taking a few cues from another familiar "wand," this would-be device employs a sensor on the front to determine the distance to the object it's pointed at, which gets relayed to the user in the form of varying levels of vibration. Needless to say, there's no indication of it actually moving beyond the concept stage, but it certainly doesn't seem beyond the realm of possibility.[Via OhGizmo]
Zen concept PC caters to visually impaired
There's hardly a shortage of pocketable devices for the blind, but the Zen is lookin' out for the visually impaired who crave a more full-fledged computing experience. Essentially, the Sandbox PC (hardware) and Zen (operating system) would team up to "create a computing environment that could be used with eyes closed." More specifically, it would utilize an Active Surface for displaying text in Braille and producing images, windows and icons that could be felt. No word on whether this contraption would handle other tasks such as reading one's e-mail aloud or enabling the blind to still participate in Hot or Not, but nevertheless, it's definitely a step in the right direction.
knfbREADER Mobile uses Nokia N82 as text-to-speech device
The K-NFB, a joint venture between Kurzweil Technologies and the National Federation of the Blind, introduced knfbREADER this week, a text-to-speech program for the N82. Coupling Kurzweil's image processing with the N82's camera, a user only has to snap a pic of the document to be read and the software will speak it back and allow you to follow along on the handset's screen as it highlights each word read. The device is able to read just about all printed materials, from newspapers to glossy printed material and even US currency. Compared to earlier products -- dating way back to giant contraptions in the early 80's -- this tiny package will be a boon for the visually impaired, as there's now no need to drag something around that's the size of a photocopier. We're hoping that we see this offering expand to other sets with capable cameras, and that the pricing gives all a warm fuzzy feeling.[Via Yahoo News]
Japan's AMEDIA shows off 18 new devices for the visually impaired
A trade show held in Japan recently called AMEDIA showed off 18 new products aimed at helping the visually impaired better utilize technology. Among the devices on offer were an adaptive Braille display, which can convert text from a PC screen into the hand-read alphabet in real time, the REHA Vision "Color Talk," a handheld scanner which can recognize 220 colors and speak them to the user, and what appears to be GW Micro's VoiceSense PDA (here being employed to help those with visual impairments in the IT sector). The collection of gadgets clearly illustrates the kind of time and energy being put into making modern technology more accessible to everyone. Hit the read link for a (translated) tour of the show.
SWAN: System for Wearable Audio Navigation
A team of Georgia Tech researchers have devised a wearable computer system that promises to help blind people navigate unfamiliar areas, and please the acronym police as well. Like most prototypes, the the SWAN (System for Wearable Audio Navigation) is pretty bulky in its current form, with a laptop, GPS, inertial sensors, pedometer, RFID tags, RF sensors, a compass, and other gear all stuffed into a backpack, although they're apparently already working on a smaller version. To get navigation information to the wearer, the SWAN employs a pair of "bonephones" (also developed by Georgia Tech), which send sounds to the person using bone conduction, letting them keep their ears free to hear what's going on around them. Instead of using traditional voice navigation, however, the SWAN uses what the researchers call "3D audio cues," which consist of navigational beacons that the person is supposed to walk towards, and secondary sounds informing them of nearby objects or changes in walking surfaces. Makes the UltraCane seem a little old-fashioned, no?[Via Roland Piquepaille's Technology Trends]
