  • Publication number: 20240074818
    Abstract: An information processing system comprises a control unit configured to execute each of the following steps. A reading step reads reference information on a reference maneuver that is a medical maneuver to be referred to by a user. The reference information includes a three-dimensional position of a track point in the reference maneuver. A first reception step receives a captured image of an external world as viewed by the user. A generation step generates, based on the three-dimensional position of the track point and the captured image, display information for presenting augmented reality regarding the reference maneuver to the user. The augmented reality three-dimensionally reproduces an aspect of a medical instrument used in the reference maneuver or a hand manipulating the medical instrument.
