The Microsoft Surface Pro will have its thinner keyboard in the future and said to be cut or etch to reach the new size.
Based on the report of Windows United, the sketch given by the Microsoft’s patent, has a new system with a description “Techniques for a circuit board for an input device are described. In at least some embodiments, an input device is integrated with a circuit board of a device. For example, a touch interaction area of the input device is formed by cutting and / or etching a portion of the circuit board such that the touch interaction area is movable with respect to adjacent portions of the circuit board. In one or more embodiments, an input device includes a switch such that movement of the touch interaction region actuates the switch to generate a click-enter event.”
The new Surface model will have more changes and improvements.
