METHODS FOR BEHAVIOR PATTERN ANALYSIS
First Claim
1. An analytic method for a behavior pattern, the method comprising:
- (a) continuously detecting behavior signals of a subject by using a tri-axis accelerator;
(b) dividing the behavior signals as n time windows based on a predetermined time length, n being a plural number;
(c) configuring the n time windows as a matrix of an X-axis and a Y-axis;
(d) performing a cross analysis on the n time windows at the X-axis and the n time windows at the Y-axis to obtain a plurality of preferred correlation values; and
(e) estimating a pattern according to the plurality of preferred correlation values to evaluate the behavior pattern.

Abstract
Disclosed is a method for behavior pattern analysis, in which the behavior signals of a subject are continuously detected using tri-axis accelerator, and the behavior signals are divided as a plurality of time windows based on a predetermined time length. The plurality of time windows are configured as an X-Y matrix, and cross analysis is performed on the time windows as X-axis and Y-axis to obtain a plurality of correlation coefficients as being the preferred correlation values. A pattern with bright spots and dark spots is plotted according to the preferred correlation values, and behavior pattern is evaluated from the number and distribution of bright spots and the pattern. The behavior consistency of a subject can be efficiently evaluated, and his/her behavior abnormality, disease development or other situations can be determined accordingly.
