Abstract

An information processing apparatus includes a plurality of information input units inputting information including image information or sound information in a real space, an event detection unit analyzing input information from the information input units so as to generate event information including estimated position information and estimated identification information of users present in the real space, and an information integration processing unit setting hypothesis data regarding user existence and position information and user identification information of the users in the real space and updating and selecting hypothesis data based on the event information so as to generate analysis information including user existence and position information and user identification information of the users in the real space.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a program. Specifically, the present invention relates to an information processing device for receiving input information (for example, information such as images, sounds, etc.) from the outside and performing analysis of an external environment (for example, analysis of a speaker) based on the input information , Information processing methods and procedures. Background technique [0002] A system that performs processing (for example, communication or interaction) between a human and an information processing device such as a PC or a robot is called a human-computer interaction system. In this human-computer interaction system, an information processing device such as a PC or a robot receives image information or sound information, and performs analysis based on the input information to recognize human actions such as human movements or utteranc...
