A tablet that integrates the sense of touch

 The Finnish company Senseg has created a tablet based on technology
 Haptic that integrates the sense of touch . This new technology
 allows to feel under the fingers textures on the screen . Microsoft
 goes even further by inventing the touchscreen with 3D effect return .
This potential opens up new dimensions in the field of
 video games . It will also revolutionize braille for the blind
 and visually impaired , which will now have access to the shelves and
 smartphones.
 The principle of this haptic technology is based on Coulomb's law .
 An electric force acts on two electrostatic charged particles
 and immobile . The electrostatic field produces a sort of friction provo-
 as the sensation of touch. Senseg announced this tablet for 2014 .
 At Microsoft, the researchers started with a standard 3D screen 24 power
 those which they superimposed a touchscreen . Between the two surfaces , they
 intercalated force sensors that detect the pressure on
 screen . At the rear of the device called 3D haptic touch , arm
 robot in contact with the slab and which moves back and forth
 produces the desired vibration when pressure is applied on the
 touchpad. To illustrate the operation of their system,
 Mike Sinclair, Michel Pahud and Hrvoje Benko , the three engineers
 Microsoft Research behind the project, have developed a game
 involves manipulating five objects of shape and texture differences
 your . There is a cube representing the stone , which returns a sen-
 hardness tion to the touch and that it moves less easily
 the sponge , which we feel under the finger flexibility through
 the haptic effect .
The user can also manipulate a cup, a wooden cube and a ball used to understand what
 Microsoft team defines as an "experience " visuohaptique "3D ". The same system would
 perceive the contours of a surface.
 3D Haptic Touch 's designers are considering several opportunities, including in medicine, by offering
 such practitioners the ability to add a physical sensory feedback when analyzing images of organs .
 The technology also has potential for education , in order to reach students with rare materials
 or dangerous and perform simulations. Another area of ​​expertise is of course that of video games,
 who can find many ways to exploit the effect return on a 3D screen.
