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.
When a person touches the prototype it pushes back with a light force to ensure one of their fingers stays in contact with the screen.
If they then press against it the robotic arm instantly pulls the screen backwards in a matching smooth movement. If they start to retract their finger, it moves it back towards them.
Meanwhile a computer adjusts the size and perspective of the on-screen graphics to create a 3D effect.
The trick to simulating a physical sense of touch is to adjust the amount of force-feedback resistance.
