SYSTEM AND METHOD FOR DEVICE POSITION CLASSIFICATION

摘要

A system and method for classifying a position of a device may include processing one or more respective signal characteristics of one or more signals indicative of device orientation to determine a position of a device relative to a user. In a non-limiting example, various aspects of this disclosure include analyzing, over time, one or more characteristics of a first signal indicative of the alignment of a first device axis with a reference direction and one or more characteristics of a second signal indicative of the alignment of a second device axis with the known direction, and determining the position of the device based at least in part on such analysis. One or more analyzed signals may, for example, correspond to and/or be derived from MEMS sensor signals.

1. A system for classifying position of a device, the system comprising:
at least one module operable to, at least:
receive a discrete time signal representation of a rotation matrix coefficient;analyze a first characteristic of the discrete time signal;analyze a second characteristic, different from the first characteristic, of the discrete time signal; andclassify the position of the device based, at least in part, on the analysis of the first characteristic and the analysis of the second characteristic.
