Fujitsu has unveiled an interesting prototype haptic feedback tablet at MWC 2014. The tablet has special technology that makes the screen feel smooth or rough allowing the user to feel images on the screen. The technology behind the haptic system was developed at Fujitsu Laboratories. The tech is able to create tactile sensations by varying the friction between the touchscreen and the user’s finger.
The technology uses ultrasonic vibration on the surface of the screen to create high-pressure air layer between the user’s finger and the screen. The air between the screen and the finger reduces friction creating a floating effect. This allows the screen to have a slippery sensation. Fujitsu is then able to cycle that air cushion at a fast rate creating the ability to make a rough feeling screen.
Fujitsu says that it has worked to reduce the power needed by the haptic system. The tech is integrated into a tablet on display at MWC 2014. The tablet allows the user to feel CDs on the screen and gives the user the feeling of plucking strings on a Japanese harp on the screen. Fujitsu wants to commercialize the tech by 2015.
