Abstract
System, method, and computer program products are provided that can support touch interaction from multiple users on a large scale projective capacitive (PCAP) display system, such as a gaming table. According to some embodiments, a system includes a touchscreen coupled to a controller. The controller adjusts performance of the touchscreen through dynamically setting a controller parameter to support altered touch reporting in a first area of the touchscreen compared to a second area of the touchscreen. The controller enables touch detection for the first area according to performance characteristics needed for an application operating in the second area. Some embodiments include the controller identifying a user associated with the first area, where the controller receives and analyzes a watermarked touch signal from the first area that includes a touch signal and a unique signal, detects an associated touch location, and detects the unique signal associated with the user.
