INFORMATION PROCESSING SYSTEM AND METHOD
First Claim
1. An information processing system comprising:
- a sensor for measuring the human acceleration produced by human movement for a predetermined time period;
a processing part for obtaining feature data related to the speed of human movement based on the measured acceleration data; and
a storage part for storing the obtained feature data,wherein the processing part includes;
obtaining the speed of movement per predetermined unit time from the acceleration data measured by the sensor;
counting the speed of movement above a reference value, from the obtained speed of movement per unit time, with respect to each of a plurality of reference values of the speed of movement, as the cumulative frequency for the reference value of the speed of movement; and
obtaining statistical data based on the distribution between the reference values of the speed of movement, and the log of the cumulative frequency for the reference values, as the feature data of human movement, and storing the feature data in the storage part.

Abstract
An information processing system includes a sensor node and a server. The sensor node obtains acceleration data and transmits the data to the server. The server obtains and records the number of zero crossings from the acceleration data. The server obtains and records the frequency distribution of the number of zero crossings. The server obtains one or more of the following: the slope of the approximate line of the distribution; the linearity of the distribution; the inflection point; the slope of the approximate line in the zero crossing range below the inflection point; the slope of the approximate line in the zero crossing range above the inflection point; the linearity of the distribution in the zero crossing range below the inflection point; and the linearity of the distribution in the zero crossing range above the inflection point. Then, the server records the obtained value.
