Abstract: An information processing system includes an identification unit configured to identify unique information on shoes using at least part of a captured image of the shoes, and a setting unit configured to set an association between an acquisition device configured to acquire the unique information and a module device attached to the shoes based on the unique information.

Abstract: An information processing system includes an acquisition unit configured to acquire sensing data from a sensor device used for a foot, and a determination unit configured to determine an attached state of the sensor device to the foot according to a motion of the foot calculated using the sensing data.

Abstract: An information providing system according to an aspect of the present disclosure is an information providing system for providing product information requested by a store visitor, and includes: a detection unit that detects a finger pointing of a person from an image acquired by an imaging device, a specifying unit that specifies a product from a direction of the finger pointing, and a display unit that displays product information of the specified product in a case where a specified elapsed time exceeds a predetermined time.

Abstract: A spatial infection risk determination system according to one aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: detect a person from a captured image in a space acquired by an imaging device; and determine an infection risk in the space based on a floor area of the space and an area of a circle whose center is the detected person, the area of the circle being based on a distance to prevent infection of an infectious disease.

Abstract: To make it easy to recognize whether each person is in a situation in which the person may catch an infectious disease, the present invention provides an information output apparatus 10 including an acquisition unit 11 that acquires a captured image acquired by photographing a space, a detection unit 12 that detects a person from the captured image, a determination unit 13 that determines a radius of a circle to be displayed over the captured image in an overlapping manner according to a predetermined condition, and a display control unit 15 that displays an image in which a circle surrounding each of the detected persons is displayed over the captured image in an overlapping manner.
