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 an embodiment, 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. An altered touch reporting area may be a fast scan area or a slow scan area. In addition, enrichment data areas may include at least one of a fast scan area, a slow scan area, or an area of a touchscreen during a full scan.
