Autodesk researchers develop 'magic finger' that reads gestures from any surface (video)

Steve Dent — Mon, 22 Oct 2012 08:49:00 -0400

By combining a camera that detects surfaces with one that perceives motion, Canadian university researchers and Autodesk have made a sensor that reads finger gestures based on which part of your body you swipe. The first camera can detect pre-programmed materials like clothing, which would allow finger movements made across your pants or or shirt to activate commands that call specific people or compose an email, for instance. Autodesk sees this type of input as a possible compliment to smartphones or Google Glasses (which lack a useful input device), though it says the motion detection camera isn't accurate enough yet to replace a mouse. Anyway, if you wanted that kind of device for your digits, it already exists -- in spades.

OpenGL ES 3.0 and OpenGL 4.3 squeeze textures to the limit, bring OpenVL along for the ride

Jon Fingas — Tue, 07 Aug 2012 04:54:00 -0400

Mobile graphics are clearly setting the agenda at SIGGRAPH this year -- ARM's Mali T600-series parts have just been chased up by a new Khronos Group standard that will likely keep those future video cores well-fed. OpenGL ES 3.0 represents a big leap in textures, introducing "guaranteed support" for more advanced texture effects as well as a new version of ASTC compression that further shrinks texture footprints without a conspicuous visual hit. OpenVL is also coming to give augmented reality apps their own standard. Don't worry, desktop users still get some love through OpenGL 4.3: it adds the new ASTC tricks, new visual effects (think blur) and support for compute shaders without always needing to use OpenCL. All of the new standards promise a bright future in graphics for those living outside of Microsoft's Direct3D universe, although we'd advise being patient: there won't be a full Open GL ES 3.0 testing suite for as long as six months, and any next-generation phones or tablets will still need the graphics hardware to match.

University of Tokyo builds a soap bubble 3D screen, guarantees your display stays squeaky clean (video)

Jon Fingas — Fri, 29 Jun 2012 20:58:00 -0400

There are waterfall screens, but what if you'd like your display to be a little more... pristine? Researchers at the University of Tokyo have developed a display that hits soap bubbles with ultrasonic sound to change the surface. At a minimum, it can change how light glances off the soap film to produce the image. It gets truly creative when taking advantage of the soap's properties: a single screen is enough to alter the texture of a 2D image, and multiple screens in tandem can create what amounts to a slightly sticky hologram. As the soap is made out of sturdy colloids rather than the easily-burst mixture we all knew as kids, users won't have to worry about an overly touch-happy colleague popping a business presentation. There's a video preview of the technology after the jump; we're promised a closer look at the technology during the SIGGRAPH expo in August, but we don't yet know how many years it will take to find sudsy screens in the wild.

Cyclone Display exemplifies 'multi-colored expression,' totally heading to a nightclub near you (video)

Darren Murph — Fri, 12 Aug 2011 22:37:00 -0400

Ever heard of Yoichi Ochiai? You have now. Hailing from Japan's University of Tsukuba, this whizkid was on hand here at SIGGRAPH to showcase one of his latest creations -- and it just so happened to be one of the trippiest yet. The Cyclone Display was a demonstration focused on visual stimulation; a projector shown above interacted with a plate of spinning disks. Underneath, a cadre of motors were controlled by a connected computer, and as the rotation and velocity changed, so did the perceived pixels and colors. The next step, according to Ochiai, would be to blow this up and shrink it down, mixing textures in with different lighting situations. With a little help, a drab nightclub could douse its walls in leopard print one night, or zebra fur another. Interactive clubbing never sounded so fun, eh? You know the drill -- gallery's below, video's a click beneath.

MS applies for patent on 'light-induced shape-memory,' a touchscreen that could touch back

Tim Stevens — Mon, 29 Nov 2010 11:56:00 -0500

Touchscreens are selfish lovers, taking your gentle caresses and impatient taps without offering a hint of feedback to you. We've seen attempts to change that, like prototypes from Toshiba and Senseg that add a bit of texture to a touchable surface, but now Microsoft might be looking to bring such dynamic tactility to the one of the biggest touchable surfaces: Surface. A recent patent application entitled "Light-induced Shape-memory Polymer Display Screen" describes a technique for a display that uses infra-red light to detect touch, but also to "selectively change a topography of the topography-changing layer." In other words: to make it bumpy or smooth. Certain wavelengths of light projected on the screen can cause areas of that topography layer expand or contract, which could finally mean all our cries for attention might finally be responded to in kind.

Toshiba brings texture to touch (video)

Vlad Savov — Fri, 21 May 2010 13:39:00 -0400

Reach out and touch whatever screen you're reading this on. What if, instead of feeling the glass or plastic beneath your finger, you could experience the texture of a brush, woodgrain, or even a stone? Well, Toshiba's working on just such a project, which operates on the basis of a film affixed to, say, a smartphone's touch panel -- electrical currents are sent through this layer, and your digits are shot up with the simulated sensation of touching those various surfaces. Senseg, the company behind this tech, has been around since 2008, but perhaps this recent prototype demo is a sign that things might actually start going places. It's not like there'll be a shortage of imaginative uses for such precise tactile feedback. Video after the break.

Sony shows that 'C' stands for Crocodile with skinned VAIO Type C

Tim Stevens — Tue, 07 Apr 2009 08:14:00 -0400

Shattering misconceptions that crocodiles only come in various shades of dark, menacing green, Sony has managed to genetically engineer crocs in girly pink, luscious red, and chocolaty brown colors exclusively for the sake of wrapping its CS series VAIO notebooks in organic texture. Mind you, textures are all those crocs sacrificed, as like the company's earlier Crocodile-themed machines these lappys are still made entirely of plastic and bits of silicon -- just grooved and pigmented to look like prehistoric, genetically modified reptiles (check out the detail pic after the break). The crocette devices, which are otherwise identical internally to those sporting myriad of other hues, hit Japan on the 18th for ¥104,800 (just over $1,000), and while Sony hasn't announced any plans for an international release, we're thinking if you head on down to Florida you could find yourself a good 'ol boy who could whip up one of these in no time and make a rib-stickin' stew with the remains.
