Microsoft develops 3D touchscreen with tactile feedback

BBC: "Details of a touchscreen showing 3D images that can be felt and manipulated have been published by Microsoft's research unit.

The project combines an LCD flat panel screen with force sensors and a robotic arm that moves it back and forwards.

By controlling how much resistance there is to a user's fingertip the firm says it can simulate the shape and weight of objects shown on screen.

Microsoft says the device could have medical uses as well as for gaming."
