The control software can be configured to automatically load layouts based on the active program or game being played. The touchscreen configuration for each game may be programmed with bitmaps and key sequences and then stored for later retrieval. In order to provide rapid retrieval of a configuration, the touchscreen device is connected to the system through the USB port rather than the keyboard port. Once a layout is loaded onto the touchscreen display, the input device senses pressure on the integral touchscreen. Wh…
