    How does it work?

    Step 1: Template creation (Projection Module)
    A template of the desired interface is projected onto the adjacent interface surface. The template is produced by illuminating a specially designed, highly efficient holographic optical element with a red diode laser.
    Note: the template serves only as a reference for the user and is not involved in the detection process. In a fixed environment, the template can just as easily be printed onto the interface surface.

    Step 2: Reference plane illumination (Micro-illumination ModuleTM)
    An infra-red plane of light is generated just above, and parallel to, the interface surface. This light is invisible to the user and hovers a few millimeters above the surface.
    When the user touches a key position on the interface surface light is reflected from this plane in the vicinity of the key and directed towards the sensor module.

    Step 3: Map reflection coordinates (Sensor Module)
    Reflected light from user interactions with the interface surface is passed through an infra-red filter and imaged on to a CMOS image sensor in the sensor module.
    Custom hardware embedded in the sensor chip (the Virtual Interface Processing CoreTM) then makes a real-time determination of the location of the reflected light.
    The processing core can track multiple reflection events simultaneously and can thus support both multiple keystrokes and overlapping cursor control inputs.
