Portable device holstering response

摘要

A portable device automatically stores information (including, if desired, a timestamp) regarding user-interface interactions and then, in response to detecting holstering of the portable device, automatically uses that information to revert to an earlier user-interface interaction-directed state when at least one reversion criterion is also met. The reversion criterion can comprise a set duration of time. This use of the information to revert to an earlier user-interface interaction-directed state can comprise deleting at least some of the information from storage to identify the particular user-interface interaction to be used to determine the earlier user-interface interaction-directed state.
