US Patent 8694791 Transitioning between access states of a computing device

Aspects of this disclosure are directed to outputting, for display at a presence-sensitive display, a first set of two or more selectable objects in a first arrangement of locations, the computing device operating in a first instance of a limited access state. At least one of the selectable objects includes an element of a predetermined passcode. The computing device may receive an indication of a first gesture to select one of the selectable objects and an indication of a second gesture to designate the selected object as an element of a candidate passcode. The computing device may transition to an access state based at least in part on a comparison between the candidate passcode and the predetermined passcode. The computing device may transition to a second instance of the limited access state, and may output a second set of two or more selectable objects in a second, different arrangement.
