The product 3D Touchscreen includes a piece of LCD flat panel screen with strong sensors and a robotic arm which can move it back and forwards. If you want to know how much resistance there is to a user's fingertip the firm , you can see the figures on screen. Microsoft company says the device 3D Touchscreen could have medical usages as well as for gaming. Jobs on the project is being carried out at the firm's Redmond campus near Seattle
Simulated shapes
If a person touches the prototype 3D Touchscreen it pushes back with a light force to make sure one figure stays in contact with the screen.
When they then press against it the robotic arm quickly pulls the screen backwards in a matching smooth action. If they begin to retract their finger, it moves it back towards them.
At the same time 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.
