An information processing device includes: a posture change determining unit that determines, based on an output value of an inertial sensor, whether a posture state of a moving object has changed; a reference orientation generating unit that, when it is determined that the posture state of the moving object has changed from a first posture state into a second posture state, generates a reference orientation corresponding to an orientation of the moving object at that time calculated from the output value of the inertial sensor; and an orientation error calculating unit that, when it is determined that the posture state of the moving object has changed from the second posture state into the first posture state, calculates an error of an orientation of the moving object according to the reference orientation, and an orientation at that time calculated from the output value of the inertial sensor.

A propagation optical system includes: a first optical system; an intermediate optical element; and a second optical system. The first optical system, the intermediate optical element, and the second optical system being sequentially arranged in a direction from the image display element toward the light guide member along an optical axis. The intermediate optical element has a non-rotationally symmetric curved surface, of which shape is non-rotationally symmetric about the optical axis. A cross-sectional shape, of the non-rotationally symmetric curved surface, in a first plane including the optical axis is non-arc shape. The first plane is a plane in which the non-rotationally symmetric surface has a strongest positive power among planes including the optical axis. The propagation optical system is configured to form, between the first optical system and the second optical system, an intermediate image corresponding to an image displayed on the image display element.

A management server communicable with a plurality of terminal devices, including a first terminal device, includes: a receiver to receive, from the first terminal device, shared information to be shared between the plurality of terminal devices, the shared information including first location information indicating a current location of the first terminal device, direction information indicating a direction that the first terminal device faces, and distance information indicating a distance from the first terminal device to a target destination; circuitry to generate target destination information including second location information indicating a location of the target destination based on the shared information received from the first terminal device; and a transmitter to transmit the target destination information to the plurality of terminal devices for display at the plurality of terminal devices.
摘要:
A monocular image display device includes a virtual image former to display an image in front of one eye of a user and a primary light amount adjuster being in front of another eye of the user. The primary light amount adjuster is disposed closer to the one eye of the user than an optical axis of the another eye of the user is.
