1. A wearable computing device comprising a processor and a first accelerometer connected to the processor, the wearable computing device configured to attach to a wrist of a user'"'"'s hand, wherein:
- the first accelerometer is configured to determine a first motion indicator indicative of a motion of the wearable computing device; and
the processor is configured to execute a context-specific action selected according to a user activity context determined according to the first motion indicator and according to a second motion indicator indicative of a motion of a mobile telephone communicatively coupled to the wearable computing device, the second motion indicator determined by a second accelerometer of the mobile telephone, wherein the user activity context is determined according to a degree of periodicity of the motion of the wearable computing device, and further according to a degree of periodicity of the motion of the mobile telephone, and wherein determining the user context comprises;
when both the motion of the wearable computing device and the motion of the mobile telephone are periodic, determining that the user is currently performing a first activity,when neither the motion of the wearable computing device, nor the motion of the mobile telephone is periodic, determining that the user is currently performing a second activity, andwhen only one of the motion of the wearable computing device and the motion of the mobile telephone is periodic, determining that the user is currently performing a third activity.

Abstract
Described systems and methods enable the detection of a user activity context indicative of a user'"'"'s current activity, by correlating the motion of a wrist-worn device (e.g., watch) with the motion of a mobile telephone. Some embodiments further correlate motion data with a location indicator provided by the mobile telephone, and with a current time of the day. The watch and/or mobile telephone may switch to a context-specific operation mode in response to determining the user activity context.
