Patent Images
1. An mobile device to monitor human activity using multiple sensors comprising:
- a plurality of sensors;
a dedicated processing unit receiving data from the plurality of sensors, the dedicated processing unit to process sensor data, the dedicated processing unit further comprising a calculating logic to compare a first estimation of a user activity statistic based on data from a first sensor with a second estimation of a user activity statistic based on data from a second sensor, and calculating the user activity statistic based on the first estimation and the second estimation, wherein the calculated user activity statistic is a result of a weighted combination of the first estimation and the second estimation; and
a central processing unit to perform functions in the mobile device.

Abstract
A mobile device monitors accelerations using one or more inertial sensors. A user activity is identified based on the accelerations. A first estimation is made of a user activity statistic associated with the user activity based on the accelerations. Location information is obtained by one or more location based sensors. A second estimation is made of the user activity statistic based on the location information. The user activity statistic is calculated based on the first estimation and the second estimation.
