Abstract: A wearable device includes a first device wearable by a user, a second device wearable by the user, and circuitry to cause the first device to obtain a surrounding image having an image capture range including a range out of a visual field of the user. The circuitry further causes the second device to project a projection image determined based on the surrounding image onto a projection destination determined based on the surrounding image.

Abstract: An information display system includes circuitry to acquire detection information including information on a posture of a user and information on a line of sight of the user, project an image onto a projection destination located in a projection direction with respect to the user, and cause the image to be projected onto the projection destination based on the detection information and information on the projection direction.

Abstract: An information processing apparatus includes circuitry to obtain, from a memory, projection information based on information on a position of a user. The information on the position of the user is obtained by a device worn by the user. The projection information is to be projected by the device worn by the user. The circuitry obtains projection destination information. The projection destination information is information on a projection destination onto which the projection information is to be projected. The circuitry causes the device to project the projection information onto the projection destination based on the projection information and projection destination information.

Abstract: A coefficient to transform a three-dimensional mesh approximating at least a part of a three-dimensional model including at least a part of a target object and generated from a plurality of two-dimensional images, into two-dimensional panoramic coordinates is determined. A first position on a first image determined from a plurality of two-dimensional images corresponding to a portion of the two-dimensional panoramic coordinates, and an annotation to be projected onto the two-dimensional panoramic coordinates are specified according to the first image. A second position corresponding to projection of the annotation onto the two-dimensional panoramic coordinates is determined. The annotation is superimposed on a second image obtained by projecting the first image onto the two-dimensional panoramic coordinates. A third position corresponding to projection of the first position onto a third image is determined, and the annotation is projected and superimposed at the third position on the third image.
