Abstract: To be capable of efficiently transmitting appropriate information on the motion improvement to a person in motion. A motion evaluation system includes a sensor unit, an information processing device, and an information presentation device. The information processing device includes a communication device, a storage device, and an arithmetic device. The arithmetic device acquires motion data acquired by observing a user through the use of a sensor via the communication device, checks the motion data against information about the correctness of motions in the reference information, determines a state of motion of the user, specifies a motion in a state to be improved as an improvement, check the motion data after the motion corresponding to the improvement against information about busy levels of the user to specify a busy level of the user, and outputs, as improvement suggestion information about the improvement, information with different contents at each of multiple times to an information presentation device based on the improvement and a rule predetermined according to each situation of the busy level.

Abstract: Provided is a posture recognition system that can properly respond to an error that is changed according to a user's motion. A posture estimation section calculates posture data indicating a posture of a user wearing clothing, on the basis of motion data measured by a posture sensor attached to the clothing. An error estimation section calculates error data which is an estimate of an error that is occurring in the posture data, on the basis of the motion data and the posture data.
