1. A wearable device to be worn by a user during an activity, the wearable device comprising:
- a motion sensor to collect motion data of the user during the activity; and
processing logic stored in a memory element of the wearable device and comprising instructions executable by a processor to;
receive motion data collected by the motion sensor;
determine a magnitude of the motion data by taking the magnitude of an acceleration signal, applying a high-pass filter to the acceleration signal, and integrating the standard deviation of the high-passed acceleration signal over a period of time;
determine a frequency of the motion data; and
identify the activity in which the user is engaged based on the magnitude and the frequency of the motion data.

Abstract
A wearable device automatically identifies an activity in which a user of the device is engaged while wearing the device. The wearable device receives motion data of the user collected during the activity and determines a magnitude and a frequency of the motion data. Based on the magnitude and frequency of the motion data, the wearable device identifies the activity in which the user is engaged.
