Patent Images
1. A system for activity classification, the system comprising:
- at least one module operable to, at least;
receive a sensor signal;
form a plurality of filtered sensor signals by, at least in part, filtering the received sensor signal with a plurality of respective band-pass filters; and
identify an activity class based, at least in part, on the plurality of filtered sensor signals.

Abstract
A system and method for efficiently and accurately classifying user activity. In a non-limiting example, accelerometer signals and/or gyroscope sensor signals may be analyzed to classify user activity, for example, that of a user of a handheld and/or wearable device. Information from additional sources and sensors (e.g., other inertial sensors, non-inertial sensors, passive sensors, etc.) may also be utilized.
