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 biometric system includes: a camera that captures a subject; a pressure information collection unit that detects a pressure value of at least one sole of the subject; a skeleton direction vector calculation unit that calculates a skeleton direction vector of the subject captured by the camera; a floor reaction force vector calculation unit that calculates a floor reaction force vector on a basis of information on pressure from the pressure information collection unit; and an analysis result output unit that displays, in a superimposing manner, the skeleton direction vector calculated by the skeleton direction vector calculation unit and the floor reaction force vector calculated by the floor reaction force vector calculation unit.

Abstract: A watching system, which calculates a fall probability of an imaged person to be fallen using a computer which includes a processor and a memory, includes a trunk extraction unit that receives time-series skeleton information of the imaged person, calculates an angle between a head and a waist of the imaged person based on the skeleton information, extracts the angle as a trunk of the imaged person, calculates the center of the trunk as a trunk center based on trunk information set in advance, extracts a trunk to be reference as a reference trunk from a time-series trunk calculated from the time-series skeleton information, and holds a center of the reference trunk, and a fall probability calculation unit that calculates a distance between a trunk center of the reference trunk and a trunk center of the trunk as a deviation amount, and calculates the fall probability from the deviation amount.
