Patent ID: 8615375

Claim:
A motion determination apparatus, comprising: a computer processor to execute: acquiring, at intervals, detection information, which indicate a change in a position and/or a posture, of a motion sensor and/or a device including the motion sensor, and storing the detection information with acquisition time information of the detection information mapped to the detection information; calculating from the detection information a plurality of feature quantities indicating features at a plurality of different time points; and determining a motion applied to the motion sensor and/or the device including the motion sensor, in response to a feature quantity selected from among the plurality of calculated feature quantities, wherein the calculating: calculates one of the feature quantities from the detection information at a specific time period later than a time period when a value of the detection information rises above a specific value, and calculates, for detection of a transition, another one of the feature quantities from the detection information at a specific time period later than a time period when a value of the detection information rises again above the specific value after the value of the detection information falls below the specific value.
