Software giant Microsoft has developed a 3D touchscreen. It includes an LCD flat panel screen with force sensors and a robotic arm that moves it back and forwards and by controlling to a user’s fingertip. The device can simulate the shape and weight of objects shown on screen.

Senior researcher said that when the finger pushes the touchscreen and senses merge with stereo vision, if convergence is done correctly and visuals are updated constantly so that they correspond to the finger’s depth perception, it will be enough for the brain to accept the virtual world as real.
