Microsoft develops 3D touchscreen with tactile feedback

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.

Work on the project is being carried out at the firm's Redmond campus near Seattle.
