>>Late last week the US Patent & Trademark Office published a patent application from Apple that revealed yet another take on a possible future virtual keyboard for the iMac and other devices.
Glass Keyboard with Graphics on a Display Screen Below
In a glass embodiment, the keys may be painted on the surface or provided as graphics on a display screen located below the glass surface. The flat surface keyboard includes an indication of a standard computer keyboard layout including space bar, enter and function keys and so on.
Further, the flat surface keyboard may also include a haptic or tactile feedback mechanism that is activated when the user presses or taps on a key of the keyboard. In general, the haptic response may provide a force, vibration and/or motion to the user's fingers or hands in response to the user pressing on the keyboard surface.
