METHOD AND APPARATUS FOR CATEGORIZING DEVICE USE CASE

摘要

Systems and methods are disclosed for categorizing a device use case for on foot motion with a portable device. Motion sensor data corresponding to motion of the portable device may be obtained, such as from a sensor assembly of the device. The motions sensor data is processed. Further, a use case characteristic may be determined from the processed and/or raw motion sensor data, an effective frequency may be determined from the processed and/or raw motion sensor data and/or an Eigen use case may be determined. The device use case may then be classified using the processed and/or raw motion sensor data and at least one of the use case characteristic, the effective frequency and the Eigen use case.

1. A method for categorizing a device use case for on foot motion with a portable device comprising:
(a) obtaining motion sensor data corresponding to motion of the portable device; (b) performing at least one of:
(i) deriving a use case characteristic from the motion sensor data;(ii) determining an effective frequency from the motion sensor data; and(iii) determining an Eigen use case; and (c) categorizing the device use case of the portable device using the motion sensor data and at least one of the use case characteristic, the effective frequency and the Eigen use case.
