Abstract:
1. An interactive display system configured for multi-touch input, the interactive display system comprising: a multi-touch display; a touch detection system configured to detect a touch input on the multi-touch display and to generate a contact geometry for a contact region of the touch input and to detect a reflective tag associated with the touch input, the reflective tag encoding a touch input signature associated with touch input metadata defining one or more spatial properties about a portion of the touch input not detectable to the touch detection system; and an application programming interface executed on a processor of the interactive display system, the application programming interface being configured to receive the contact geometry from the touch detection system, to send the contact geometry associated with the contact region for the touch input to a requesting application program for application-level processing, to receive from the application program a display command based on the application level-processing, and to send the display command to the multi-touch display to adjust a display of a graphical element on the multi-touch display.
