INFORMATION PROCESSING DEVICE AND METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

An information processing device and method, a program, and a recording medium for identifying the feeling and status of a user from non-definition information such as biometric information using the information processing device. An input unit (91) obtains the pulse information and the body motion information of a user, and a characteristic extraction unit (112) generates the characteristic amount vector of the pulse information and the body motion information. A learning unit (94) compares the generated characteristic amount vector with characteristic amount vector accumulated in an accumulation unit (95), identifies the feeling and status of the user, and outputs the result to an output unit (92) via an output controller (114). The newly generated characteristic amount vector is added to the vectors accumulated in the accumulation unit (95) to recalculate the distribution of the vectors, the center of distribution, and the standard deviation, and the result is accumulated in the accumulation unit (95).
