Aspects of the present invention include a device comprising a memory storing instructions and a processing circuit executing the instructions to detect a first user action. The instructions may further include instructions to establish a first user action state based on the detected first user action, designate a first mode based on the first user action state, determine if a second user action, consistent with a first detection condition associated with the first mode, has taken place, when the second user action has taken place, establish a second user action state based on the second user action, and designate a second mode based on the second user action state, the second mode consuming more power than the first mode.
