PORTABLE DEVICE HOLSTERING RESPONSE
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.
1 . A method comprising:
automatically storing information regarding user-interface interactions for a portable device; and
in response to detecting holstering of the portable device, automatically using the information to revert to an earlier user-interface interaction-directed state when at least one reversion criterion is also met.
2 . The method of claim 1 wherein using the information comprises, at least in part, deleting at least some of the information from storage to thereby identify the earlier user-interface interaction-directed state.
3 . The method of claim 2 wherein the at least one reversion criterion comprises a duration of time, such that deleting at some of the information from storage comprises, at least in part, deleting the information for user-interface interactions that occurred prior to detecting the holstering the portable device and within the duration of time.
4 . The method of claim 1 wherein storing information comprises storing information that identifies particular user-interface interactions.
5 . The method of claim 4 wherein storing information further comprises storing a timestamp for each of at least some of the particular user-interface interactions.
6 . The method of claim 5 wherein automatically using the information to revert to an earlier user-interface interaction-directed state comprises using the timestamp to identify the particular user-interface interaction to be used to determine the earlier user-interface interaction-directed state.
7 . The method of claim 6 wherein the at least one reversion criterion corresponds to a duration of time and wherein using the timestamp to identify the particular user-interface interaction to be used to determine the earlier user-interface interaction-directed state comprises using the timestamp to identify a particular user-interface interaction that has a predetermined relationship with respect to the duration of time.
8 . An apparatus comprising:
a memory;
a user interface;
a sensor; and
a control circuit operably coupled to the memory, the user interface, and the sensor and configured to:
store information in the memory regarding user-interface interactions; and
respond to detection by the sensor of holstering the apparatus, using the information to revert to an earlier user-interface interaction-directed state when at least one reversion criterion is also met.
9 . The apparatus of claim 8 wherein the control circuit is configured to use the information by, at least in part, deleting at least some of the information from the memory to thereby identify the earlier user-interface interaction-directed state.
10 . The apparatus of claim 9 wherein the at least one reversion criterion comprises a duration of time, and wherein the control circuit is configured to delete at some of the information from storage by, at least in part, deleting the information for user-interface interactions that occurred prior to detecting the holstering the apparatus and within the duration of time.
11 . The apparatus of claim 8 wherein the control circuit is configured to store information in the memory by storing information that identifies particular user-interface interactions.
12 . The apparatus of claim 11 wherein the control circuit is further configured to store the information by storing a timestamp for each of at least some of the particular user-interface interactions.
13 . The apparatus of claim 12 wherein the control circuit is configured to use the information to revert to an earlier user-interface interaction-directed state by using the timestamp to identify the particular user-interface interaction to be used to determine the earlier user-interface interaction-directed state.
14 . The apparatus of claim 13 wherein the at least one reversion criterion corresponds to a duration of time and wherein the control circuit is configured to use the timestamp to identify the particular user-interface interaction to be used to determine the earlier user-interface interaction-directed state by using the timestamp to identify a particular user-interface interaction that has a predetermined relationship with respect to the duration of time.
15 . The apparatus of claim 8 wherein the apparatus comprises a portable communication device.
