Chilly Chair uses static electricity to raise your arm hair, force an 'emotional reaction' (hands-on video)
Hiding in the back of the SIGGRAPH Emerging Technologies demo area -- exactly where such a project might belong -- is a dark wood chair that looks anything but innocent. Created by a team at the University of Electro-Communications in Toyko, Chilly Chair, as it's called, may be a reference to the chilling feeling the device is tasked with invoking. After signing a liability waiver, attendees are welcomed to pop a squat before resting their arms atop a cool, flat metal platform hidden beneath a curved sheath that looks like something you may expect to see in Dr. Frankenstein's lab, not a crowded corridor of the Los Angeles Convention Center. Once powered up, the ominous-looking contraption serves to "enrich" the experience as you consume different forms of media, be it watching a movie or listening to some tunes. It works by using a power source to pump 10 kV of juice to an electrode, which then polarizes a dielectric plate, causing it to attract your body hair. After signing our life away with the requisite waiver, we sat down and strapped in for the ride. Despite several minutes of build-up, the entire experience concluded in what seemed like only a few seconds. A projection screen in front of the chair lit up to present a warning just as we felt the hairs jet directly towards the sheath above. By the time we rose, there was no visual evidence of the previous state, though we have no doubt that the Chilly Chair succeeded in raising hair (note: the experience didn't come close to justifying the exaggerated reaction you may have noticed above). It's difficult to see how this could be implemented in future home theater setups, especially considering all the extra hardware currently required, but it could potentially add another layer of immersion to those novelty 4D attractions we can't seem to avoid during visits to the amusement park. You can witness our Chilly Chair experience in the hands-on video after the break.%Gallery-162116%
Qumarion 3D modeling mannequin coming soon for $750, still won't play with your kid (video)
Trying to get convincing, natural poses out of 3D models can be tricky, so it's a relief that two Japanese universities' joint ventures, the University of Electro-Communications' ViVienne and the University of Tsukuba's SoftEther, are close to wrapping up work on their posable mannequin. Now called Qumarion, the model formerly known as QUMA uses 32 sensors across 16 body joints to translate the humanoid statue's pose to the computer screen simply by bending limbs, much like you would the legion of action figures you had when you were eight. Neither you nor your kids will be using Qumarion to storm Fort Barbie anytime soon, but the 120 frames per second sample rate over USB does mean that poses are mirrored in your modeling tools almost instantly. You also won't have much longer to wait to buy one for your fledgling anime production: the mannequin and custom modeling software from Celsys should be bundled together sometime within the summer for a comparatively frugal $750.
Scientists train Kinect to follow your tongue wagging
We've seen Microsoft's diverse little Xbox motion controller go on to do a heck of a lot more than the company ever indeed, but up to now, it hasn't really done much to capture the majesty that is the human tongue. Thankfully, a team of researchers at the University of Electro-Communications in Japan are working to right that wrong, developing a system that can detect tongue movements, using the relative positions of a user's eyes and nose. The feature has been demoed with an Asteroids-like shooting game -- stick out your tongue to fire and move it left or right to adjust your aim. The whole thing has some practical applications beyond just making people looking goofy on video -- scientists see it as a way to train the tongue for folks with speech and swallowing disorders, one that doesn't require an unhygienic tongue attachment. Don't worry, you don't have to attach anything to your mouth to watch the video after the break, either.
NSK developing Kinect-laced robotic guide dog for the blind (video)
Have you ever looked at a robotic dog, scratched your head and thought, "Why?" Well, NSK has just responded with a pretty valid "Because." Turns out, the Japanese manufacturer is working on a new mechanized canine that could one day serve as a guide dog for the blind. The company's latest prototype builds on the work of the University of Electro-Communications (UEC), which unveiled its first model, the NR001, in 2005, followed by an updated version (NR002) in 2007. With this third iteration, unveiled late last month, NSK and UEC have added a Microsoft Kinect sensor, which allows it to more easily identify and navigate obstacles or stairs. The quadrupedal beast can also scamper up and down steps with more grace than its predecessors, which moved more like arthropods than actual dogs. The bot's paws have also been equipped with obstacle-avoiding bumper sensors, and researchers are working on incorporating voice commands, as well. NSK says its guide dog could eventually feature GPS capabilities to provide more accurate directions for the blind and visually impaired, though it'll probably be a while before it hits the pavement; the company hopes to commercialize the dogbot by 2020. Trot past the break to see the pup in action, in a pair of demo videos.
'Phantom sensation' haptic tech recreates the feeling of getting virtually stabbed
When it comes to gaming, the more realistic the better, right? Sure, it's all fun until we start talking about being virtually sliced with a battle axe or pelted with a rocket launcher -- exactly the idea behind a new technology dubbed "phantom sensation." Researchers at the University of Electro-Communications know that to virtually recreate the feeling of touch, they need to apply vibrations to two points of skin. Taking the idea one step further, they applied the stimuli to either side of the body to mimic what it might feel like if the object actually passed through. Using a tweaked Wii, as an item in the game travels through the player's hand, the top sensor vibrates intensely at first, then subsides to zero. At this point, the bottom probe kicks in, going from zero to strong until the object is cleared -- leaving the player feeling slightly violated and virtually gored. Check out the (relatively) painless demonstration video after the break.
Tokyo school takes Facebook Poking to a creepy new level (video)
You've got to hand it to Tokyo's University of Electro-Communications, the school's researchers have presented some truly unique methods for interfacing with our electronics -- fake finger sliding, a head-mounted video display, a thing that makes it feel like you've got insects on your palm, and, of course, the old kissing machine. A few recent inventions have expanded the latter trend, giving us creative new ways of getting intimate with our machines. There's the tickle interface, for one, which beams images from a connected smartphone creating the illusion that the person on the other end is tickling your palm -- made all the more real by tactile vibration hooked up to the rear of the device. And then there's the older, oddly-named Sense-Roid, sort of a clunkier version of the Hug Shirt, which, among other things, lets you "hug yourself." Both are demonstrated in a pair of videos after the break. Whatever you do, don't miss the second one.
Touchscreen prototype brings fake insects to life with tactile sensations (video)
The laboratory that taught us all to love again via kissing machine is back, and this time, thankfully, it's got its mind on other things. Kajimoto Labs at Tokyo's University of Electro-Communications showed off a prototype for a touchscreen capable of transferring tactile information like the location of onscreen icons to the user's palm, while a layer of gel positioned behind screen helps it conform to the shape of the sensation-receiving hand. What use could such a technology serve? Well, there's surely a lot of potential here -- take, for example, visually impaired users, who don't otherwise get a lot of information from touchscreens. A less noble example was offered up by a representative from the lab in the form of game where the user can feel ants crawling on his or her hand. Terrifying, and hopefully not compatible with the lab's previous invention. Video of the touchscreen after the break.
Head-mounted display controls video camera, keeps you painfully single
At the University of Electro-Communications in Tokyo, Satoshi Nariai demonstrates something called the head-mounted Mobile Video Communication System. With acceleration and position sensors built into a head-mounted display, the remote camera moves in relation to your head's movements. The researcher sees this being used primarily for videoconferencing where he thinks it will promote effective communication by allowing eye contact. Of course, there's one problem with that -- if you're both wearing large displays on your face, how could you possibly make eye contact? Unless, of course, you paint eyes onto the outside of the display itself, Loony Tunes-style. That said, it's still an impressive piece of gear. See it in action after the break.
