To provide an information processing device and information processing method, capable of obtaining useful information in which the attitude of a target person is taken into consideration from sensor information.

[Solution]

The information processing device includes: an acquisition unit configured to acquire information indicating a measurement result from a plurality of sensor devices configured to measure a pressure distribution of an attached part of a body of a user; an estimation unit configured to estimate arrangement of a plurality of parts to which the sensor devices are attached on the basis of a captured image including the plurality of parts; and a calculation unit configured to calculate information on the plurality of parts from the information indicating the measurement result acquired by the acquisition unit on the basis of the arrangement of the plurality of parts estimated by the estimation unit.

A simulator obtains muscle activities and joint contact forces by a computer simulation according to an operating condition for moving a support base of a passive exercise machine. A condition limiting unit finds intermediate conditions corresponding to desirable muscle activities and joint contact forces from muscle activities and joint contact forces obtained with the simulator according to different operating conditions. A motion simulator moves the support base according to the intermediate conditions. A myoelectric measurement device measures myoelectric potential of a subject supported by the support base. An evaluation device selects an operating condition corresponding to a larger muscle activity quantity from measurement results of muscle activity to define it as an operating condition of the passive exercise machine.

Structural systems and method are employed including a multiplicity of computers to control the acquisition and enhancement of skilled performance or behavior. Pre-processing computers (8 and 24) each accept signals from any corresponding one of a variety of physiological or other signal transducers either in close proximity to the computer or transmitted to the computer via a telemetering system. The pre-processing computer calculates a number of different measures of this signal and makes the results known to one or more other computers. These other or auxiliary computers control presentation of a display of the data for a human observer, and perform additional calculations which determine if the processed data is within a predetermined range. This range may be a function of time and/or other variables. A measure of the error between the allowed range and the processed data is computed within these auxiliary computers. These results may be used to alter the display. They are also returned to the pre-processing computer where they may alter the pre-processing calculations. Alteration of the display and the pre-processing calculations are adapted to improve skilled performance and behavior without the intervention of a human operator other than the user.

The invention determines an efficiency value (E) denoting preferably the relative period of muscle fibre activity during a recorded period of exercise, and a spatial value (S) representing the number of muscle fibres recruited during a movement as part of the exercise or of a muscle contraction, and a temporal value (T) representing the frequency with which muscle fibres are activated repeatedly during exercise, and finally combines the efficiency value (E), the spatial value (S) and the temporal value (T) by a mathematical operation to obtain an index value (ESTi) indicative of the fitness level of the individual. The obtained ESTi score is useful for assessing the training level of an animal or human individual and the individual's potential for different types of sports and other activity. Also the effect of past training or diet can be assessed, and the possible need for changes in training or diet can be assessed.
