摘要：Computer-readable media, computerized methods, and computer systems for intuitively invoking a panning action (e.g., moving content within a content region of a display area) by applying a user-initiated input at the content region rendered at a touchscreen interface are provided. Initially, aspects of the user-initiated input include a location of actuation (e.g., touch point on the touchscreen interface) and a gesture. Upon ascertaining that the actuation location occurred within the content region and that the gesture is a drag operation, based on a distance of uninterrupted tactile contact with the touchscreen interface, a panning mode may be initiated. When in the panning mode, and if the application rendering the content at the display area supports scrolling functionality, the gesture will control movement of the content within the content region. In particular, the drag operation of the gesture will pan the content within the display area when surfaced at the touchscreen interface.
