  • Publication number: 20230079461
    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.
