Multi-sensing devices cooperative recognition system
First Claim
1. An information processing system comprising:
- a plurality of sensing nodes each of which has a position detection module;
a first master sensing node which is selected from said plurality of sensing nodes, which builds up a first network with sensing nodes each of which exists in an peripheral area of said first master sensing node, and which includes;
a position determination unit which determines a position of a moving object in a predetermined space based on position information of said moving object detected by sensing nodes in said first network;
a situation determination unit which recognizes a situation change in said predetermined space based on said position of said moving object; and
a master determination unit which selects a subsequently-operating master sensing node from the plurality of sensing nodes to build up a second network with peripheral sensing nodes among said plurality of sensing nodes in accordance with said situation change.

Abstract
Disclosed here is an information processing system capable of recognizing actions and circumstances of a user with respect to both space and time as a “situation” to recognize the user'"'"'s request using a plurality of sensing nodes that work cooperatively with each another, thereby responding autonomously to the user'"'"'s request according to the recognition results. The plurality of sensing nodes and a responding device are disposed in a target space to build up a network for recognizing the situation in the target space. And, a plurality of recognition means are used to recognize the situation with respect to both space and time related to the existence of the user. And, an integral processing portion (master) is selected from among the plurality of sensing nodes, thereby dispersing the system load. If there are a plurality of users, the system can make recognition in accordance with the request of each of those users.

9. An information processing method implemented by an information processing system including a plurality of sensing nodes each of which has a position detection module, a first master sensing node being selected from said plurality of sensing nodes and building up a first network with sensing nodes each of which exists in a peripheral area of said first master sensing node, the method comprising:
-
detecting position information of a moving object in a predetermined space by said sensing nodes in said first network; sending, by said sensing nodes in said first network, said detected position information to said first master sensing node; determining, by said first master sensing node, a position of said moving object based on said position information; recognizing, by said first master sensing node, a situation change in said predetermined space based on said determined position of said moving object; selecting, by said first master sensing node, a subsequently-operating master sensing node from the plurality of sensing nodes in accordance with said situation change; and building up, by said second master sensing node, a second network with peripheral sensing node among said plurality of sensing nodes. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
