SYSTEM AND METHOD OF POINTER DETECTION FOR INTERACTIVE INPUT |
摘要 |
The present invention relates to a method and system for determining an optical property of a pointer used in an interactive touch system. The interactive device having a touch area; a plurality of emitters on the periphery of the touch area; the emitters emitting an intensity of light into the touch area; a plurality of pointers having a distinct optical property responsive to the light; at least one detector having a field of view of the touch area. The processing structure, in communication with the emitters and the at least one detector, executes instructions from a memory to: transmit an emitter signal to at least one of the emitters initiating emission of light at the first frequency; receive at least one detector signal from the at least one detector; and determine the distinct optical property from the at least one detector signal. |
