Abstract: According to one embodiment, a display apparatus includes an image data generation unit configured to generate image data and an image projection unit configured to project a light flux including an image toward a human riding in a vehicle. The image is based on the image data. The image data generation unit is configured to generate the image data relating to the image including a first display object indicating a travel direction of the vehicle at a travel direction change point when a distance between the travel direction change point and the vehicle is a first distance. The image data generation unit is configured to generate the image data relating to the image including a second display object displayed to correspond to a position of the travel direction change point when the distance is a second distance shorter than the first distance.

Abstract: According to one embodiment, a display device includes an image data generating unit and a display unit. The image data generating unit generates image data on an image. The display unit presents a video including the image data to an image viewer on a moving body to superimpose the video on an actual outside scene. The image data includes a first display object and a second display object. The first display object includes a lower part object. The lower part object has a lower part, an upper right part and an upper left part. A length of the lower part along a normal direction is longer than lengths of the upper right and upper left parts. The second display object is disposed in the image with reference to a display position of the first display object. The second display object includes information on the moving body.

Abstract: According to an embodiment, a display apparatus includes an information acquisition unit, a control unit, and a display unit. The information acquisition unit is configured to acquire information relating to an energy efficiency of a moving body. The control unit is configured to generate image data to include a display object indicating the energy efficiency based on the information. The display unit is configured to present the image including the display object to a human viewer operating the moving body. The control unit is configured to generate the image data to include a first display object when the energy efficiency is in a first state and generate the image data to include a second display object when the energy efficiency is in a second state lower than the first state.
