Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2015084943
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To determine a movement state of a user carrying an information processing device by simple arithmetic processing.SOLUTION: An information processing device includes an acceleration sensor for detecting the acceleration of a three-dimensional space, a low-pass filter for extracting a signal of gravity component vector from a sensor output of the acceleration sensor, a time delay part for giving time delay to the signal of the gravity component vector, an inner product value calculation part for calculating an inner product value between the signal of the gravity component vector extracted by the low-pass filter and the signal of the gravity component vector with the time delay given thereto by the time delay part, a template storage part for previously storing a template showing a time change in an inner product value in prescribed movement, and a movement determination part for determining whether prescribed movement occurs by using the template to perform template matching of the time change of the inner product value calculated over a prescribed time by the inner product value arithmetic processing part.
