At the last exhibition MWC 2014 the Japanese company Fujitsu demonstrated its new development - a tablet computer with a tactile screen. True, so far this is not a finished finished product, but only its prototype.
The screen of a unique tablet is capable of transmitting tactile sensations, which will allow the user to feel the object displayed on the display by touch. For example, you may feel that the object is slippery, rough, smooth, etc.
It is alleged that the technology of ultrasonic vibrations is responsible for the transmission of tactile sensations. They create a layer of high pressure air between the display surface and the user's fingers.
Unfortunately, nothing else is known about Fujitsu's new tactile tablet. It is only reported that the company plans to release its final version in 2015.
