Region activation for touch sensitive surface

摘要

One or more regions of a touch sensitive surface can be activated individually by a user. A region defines an active input area for processing touch input events. Any touch event associated with a beginning touch event that is detected in the active area is processed for display. Any touch input event detected outside the active region that is not associated with the beginning touch event is excluded from the processing. Once a writing gesture is started in the active region, the writing gesture can extend outside of the active region so long as the writing gesture is associated with the beginning touch event.
