Abstract: The power supply device 10 including: a power transmission unit 40 that is provided on the floor part F and that extends along a slide direction in which the seat S slides; and a power receiving unit 70 that is provided to the seat S and that receives power from the power transmission unit 40 in a contactless fashion. The power transmission unit 40 is provided so that the length dimension thereof in the slide direction is longer than the length dimension thereof in a direction that is orthogonal to the slide direction, and a part of the power receiving unit 70 that receives power from the power transmission unit 40 is positioned close to the power transmission unit 40 within an installation area of the power transmission unit 40 while the seat S slides and rotates.

Abstract: An information providing apparatus includes circuitry; and a memory storing computer-executable instructions that cause the circuitry to execute acquiring behavior history information of a user in a first virtual space displayed on a user terminal operated by the user; and transmitting proposal information based on the behavior history information corresponding to attribute information of the user, as proposal information to be proposed to the user to whom a second virtual space is displayed.

Abstract: An information processing apparatus includes circuitry that invokes and causes a proxy avatar to participate in a virtual space. The proxy avatar represents a first user, and is proxy for a user avatar that participates in the virtual space. In response to receipt from a second user of a request to the proxy avatar, the circuitry executes a process based on the request based on information of a process to be performed by the proxy avatar. The information of the process is set in accordance with attribute information of the second user.

Abstract: An information processing apparatus is communicable with a user terminal operated by a user. The information processing apparatus includes circuitry. The circuitry transmits, to the user terminal, virtual space data according to which the user terminal displays a second virtual space to be called from a first virtual space. The circuitry acquires, according to an operation performed by the user on a particular object in the second virtual space, information for responding to the operation performed on the particular object from a cooperation apparatus associated with the particular object. The circuitry performs processing for responding to the operation performed on the particular object based on the information acquired from the cooperation apparatus.

Abstract: An information processing apparatus is communicable with a first user terminal operated by a first user and a second user terminal operated by a second user. The information processing apparatus includes circuitry. The circuitry generates distribution data according to which the first user terminal displays a first captured image and a second captured image, the first captured image being an image captured by a first image capturing device in a photographing direction selected by the first user, the second captured image being an image captured by a second image capturing device in a photographing direction of the second user. The circuitry transmits the generated distribution data to the first user terminal. The circuitry provides a bidirectional communication function to the first user terminal and the second user terminal.
