摘要:
Systems and methods for detecting a position of an object in a sensing region are disclosed. One system includes a position sensor having an opaque capacitive proximity sensor, a light source, and a light conductor coupled to the light source and at least partially disposed over the opaque sensor, the light conductor configured to transmit at least a portion of the light from the light source to generate driven light effects in the sensing region. The system further includes a processor configured to control production of the light, and a display configured to illustrate a digital representation based on the position. A method includes the steps of sensing a position of an object in the sensing region based on a conductive property of the object, controlling light produced by a light source, and generating driven light effects in the sensing region using at least a portion of the light.
