Working Of The Bluetooth Virtual KeyboardWorking Of The Bluetooth Virtual Keyboard

The BTVKB uses The BTVKB uses three modules to create three modules to create the keyboard technology: the keyboard technology: •The projection moduleThe projection module• The illumination The illumination modulemodule•The sensor module.The sensor module.

The first module The first module projects the keyboard projects the keyboard image onto the adjacent image onto the adjacent surface using a red laser surface using a red laser diode and highly efficient diode and highly efficient diffractive optical diffractive optical element. element.

The illumination module projects an infrared beam of The illumination module projects an infrared beam of light just above the keyboard surface. This light is invisible to light just above the keyboard surface. This light is invisible to the user and hovers a few millimeters above the surface. the user and hovers a few millimeters above the surface.

The sensor module detects the interaction of the finger The sensor module detects the interaction of the finger with the IR beam. It receives this information, interprets the with the IR beam. It receives this information, interprets the keystrokes and communicates them back to the external device keystrokes and communicates them back to the external device (PDAs, mobile phones, etc.).(PDAs, mobile phones, etc.).

Step2: Reference plane illumination Step2: Reference plane illumination (Micro-illumination ModuleTM) (Micro-illumination ModuleTM) An infra-red plane of light is generated An infra-red plane of light is generated just above, and parallel to, the interface just above, and parallel to, the interface surface. This light is invisible to the user and surface. This light is invisible to the user and hovers a few millimeters above the surface. hovers a few millimeters above the surface. When the user touches a key position on the When the user touches a key position on the interface surface light is reflected from this interface surface light is reflected from this plane in the vicinity of the key and directed plane in the vicinity of the key and directed towards the sensor module. towards the sensor module.

Why not simply build phones into mobile PCs?

The cost is too high. There are many different phone standards to choose from. There is no standard that is universally available around the world. The usage model for mobile PCs does not match that of phones.
