Abstract

The invention discloses an information processing device, an information processing method and a computer program. The information processing device includes an information input unit, an event detection unit and an information synthesizing and processing unit. An observed value including user identification data is obtained based on image and sound information from the information input unit such as video camera and microphone. Target data, which is equipped with multiple user confidence degrees, is updated, and then user is identified. User identification information in the observed value is used for updating simultaneous probability of target and candidate data corresponding to relevant user. The updating value of the probability is used for calculating the user confidence degree corresponding to the target.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a computer program. More specifically, the present invention relates to an information processing device that receives information input from the outside, such as information such as images and sounds, and performs analysis of the external environment based on the input information, particularly processing In order to analyze the location and identity of the person who is speaking, etc. The present invention also relates to an information processing method for performing such analysis processing in an information processing device. The invention further relates to a computer program for causing an information processing device to perform analysis processing. Background technique [0002] A system that performs processing such as communication and interactive processing between an individual and an information processing device such as a PC or a ro...
