Patent ID: 8660978

Claim:
A computing device, comprising: a display surface; plural input mechanisms for providing input events associated with an input action, including: a touch input mechanism for providing at least one touch input event that indicates contact of a hand with a display surface of the computing device, a pen input mechanism for providing at least one pen input event that indicates contact of a pen device with the display surface of the computing device, and at least one other input mechanism for providing at least one other input event; an interpretation and behavior selection module (IBSM) for receiving the input events; wherein the IBSM is configured to apply multiple factors to assess a level of confidence that at least part of the input action represents an unintentional contact with the display surface of the computing device; wherein the IBSM is configured to determine pen orientation information which indicates an orientation at which the pen device is held in the hand during a touch input event concurrent with at least one input event other than the touch input event, wherein the pen orientation information comprises one of the multiple factors; the IBSM being configured to apply at least one behavior to counteract effects of the unintentional contact, when the unintentional contact has been assessed.
