Abstract: A system provides, to a subject apparatus including one or a plurality of sensors, inducement information for inducing a subject to take an action for a purpose different from psychological characteristics estimation. The system receives measurement data relating to the action taken by being induced by the inducement information, the measurement data being based on measurement by the one or the plurality of sensors. The action induced by the inducement information includes designation of subject intention and a related action that is all or a part of actions excluding the designation of the subject intention. The system calculates one or a plurality of action feature values based on the related action data in the measurement data and estimates psychological characteristics of the subject based on the action feature values.

Abstract: A control apparatus presents a three-dimensional operation to a worker using cross reality. The control apparatus is configured with a computer including a calculation device that performs a predetermined calculation process and a storage device that the calculation device is able to access. The calculation device includes an acquisition unit that acquires work information of work performed by the worker. The calculation device includes a calculation unit that performs calculation to present consecutive instruction content corresponding to the work performed by the worker to the worker. The calculation device includes an output unit that outputs content. The calculation unit includes a control unit that dynamically controls a display method for the consecutive instruction content according to a spatial divergence between the work information acquired by the acquisition unit and the consecutive instruction content.

Abstract: A psychological trait estimation system provides a user with information that prompts an action for a purpose different from psychological trait estimation, receives, from an apparatus including one or a plurality of sensors, measurement data regarding an action prompted by the provided information and taken by the user, and specifies data representing designation of a user intention and data representing a relevant action based on the measurement data. The action prompted by information includes designation of a user intention and relevant actions that are all or some actions except the designation of the user intention. The system estimates a psychological trait of the user based on data representing a relevant action for one or each of a plurality of relevant actions, and outputs data representing the psychological trait having been estimated.

Abstract: An arithmetic apparatus displays a 3D work-target object in a 3D coordinate space on a display device, and receives a motion signal that is a signal representing a motion measured by any one of sensor units. When receiving the motion signal, the arithmetic apparatus identifies the measured motion based on the motion signal. When the identified motion is a motion regarding a spatial shift that is a shift of a viewpoint in the 3D coordinate space of a user, the arithmetic apparatus shifts the viewpoint in the 3D coordinate space of the user in accordance with the identified motion. When the identified motion is a hand motion regarding a work movement with respect to a work target, the arithmetic apparatus outputs output information including information representing the work movement in accordance with the identified motion.
