Abstract: A touch screen controller provides a host interrupt to a host device operating in a low power consumption mode. The touch screen controller uses gesture templates to detect gestures input via a touch screen. Each gesture template is associated with an event identifier, and each event identifier is associated an application. Each gesture template includes a template identifier, a matching threshold, a criterion, and coordinates corresponding to locations on the touch screen panel. If at least one of the coordinates corresponding to a gesture input via the touch screen satisfies the criterion included in a particular gesture template, the touch screen controller provides a host interrupt with the event identifier corresponding to that gesture template to the host device. In response to receiving the host interrupt with the event identifier, the host device exits the low power consumption mode and opens the application associated with the event identifier.
