Title:
BEHAVIOR IDENTIFICATION SYSTEM
Document Type and Number:
Japanese Patent JP2007052474
Kind Code:
A
Abstract:

To provide a behavior identification system, capable of identifying a behavior pattern of a user through a simple structure.

A transmitter 14 transmitting an infrared signal having a fixed pattern is installed to the rear head part of a user H who arbitrarily moves. On the other hand, light receiving modules 12a and 12b forming a receiver 12 detect the infrared signal transmitted from the transmitter 14, by observing two detection areas different in at least either of size and position. A main body 12c forming the receiver 12 forms a receiving frequency function showing the receiving frequency for unit time of the infrared signal detected by each of the modules 12a and 12b. The behavior pattern of the user H is identified by applying the features of two formed receiving frequency functions to a decision tree. According to this invention, the behavior pattern of the user can be identified through a simple structure.
