Abstract: An imaging device includes an imaging unit configured to capture an image of an object; a projector configured to project light onto the object; a light receiver configured to receive light reflected from the object; a determination unit configured to determine whether a presence or absence of at least one of a high reflection object, a low reflection object, a distant object, or an image blur, based on both an output of the light receiver and an output of the imaging unit; and a display controller configured to cause a display unit to present a different display according to the presence or absence of at least one of the high reflection object, the low reflection object, the distant object, or the image blur.

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 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 processing apparatus for outputting three-dimensional information that is determined based on received light includes an image capture unit configured to capture two-dimensional image information; and an output unit configured to output the two-dimensional image information for displaying, and the three-dimensional information associated with coordinates of the two-dimensional image information.
