Fujitsu Tablet Prototype Lets You Feel Rough and Smooth Textures on Screen

Posted on by

Fujitsu has rolled out a prototype tablet that has a cool bit of tech inside. The tablet has haptic sensory technology inside that allows you to feel images on the screen. Users are able to feel smooth or rough textures depending on what is displayed on the screen.

The tablet uses ultrasonic vibrations to create a cushion of high-pressure air between the finger and the screen. That air acts like a cushion and makes the screen feel very smooth. Depending on what image is on the screen, the vibrations can be rapidly cycled to create the feeling of a rough surface.

Fujitsu is showing the tech off at Mobile World Congress 2014 with several images that do things like allow the user to feel the skin of an alligator, pluck virtual strings on a harp, or feel the sensation of opening a combination lock.

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

DNP Autodesk magic finger

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

OpenGL ES 30 and OpenGL 43 squeeze textures to the limit, bring OpenVL along for the ride

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)

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

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.
