Abstract: An information processing system visualizes brain states to optimize rehabilitation programs for rapid feedback of their effects to a patient and healthcare staff, to thereby promote the efficiency of rehabilitation. An embodiment of the system includes: a storage section that stores test-result brain-state relationship information associating results of activities of multiple examinees subjected to predetermined tests with brain states of the examinees; an input section that accepts a first test result as the result of the activity of a first examinee subjected to the predetermined tests; a control section that estimates the brain state from the first test result on the basis of the test-result brain-state relationship information; and an output section that outputs the estimated brain state.

Abstract: A mood score calculation system includes a processor and a memory. The memory is configured to hold relationship information on a relationship between a mood score of a user and a statistical feature for indicating fluctuation of operational interval time of a user terminal. The processor is configured to acquire an operation log of a first user terminal. The processor is configured to calculate, from the operation log, a value of a statistical feature for indicating fluctuation of operational interval time of the first user terminal. The processor is configured to determine a mood score of a user of the first user terminal based on the value of the statistical feature and the relationship information and output the mood score.

Abstract: In a biophotonic measurement device based on the principles of near-infrared spectroscopy (NIRS), in order to realize appropriate conditions in any light-source/detector arrangement and various required specifications, a photoirradiation module 13 including a light source 101, a photodetection module 14 including a photodetector 102, and a central control/analysis unit 18 are provided. The central control/analysis unit 18 acquires correspondence relations between each of photodetection units and photoirradiation units by using a correspondence acquiring unit 19. The photoirradiation module 13 and the photodetection module 14 switch signal detection methods at each measurement point by utilizing an evaluation function value determined by detection output of the photodetector 102 so that the plurality of signal detection methods are mixable, and the high-precision and optimum biophotonic measurement device is realized.
