Abstract
Provided is a head-mounted display apparatus including: a display unit configured to display each of virtual screens that is set to each of a plurality of predetermined focal lengths; a distance-specific image generation unit configured to generate distance-specific display images for displaying, on the virtual screens, a display object representing an object to be displayed present between two focal lengths next to each other of the plurality of focal lengths; and a display controller configured to display each of the generated distance-specific display images on the virtual screen.
Claims7
A head-mounted display apparatus, comprising:
- a display that functions as a display unit that displays each of virtual screens that is set to each of a plurality of predetermined focal lengths;
- a sensor that functions as a line-of-sight detection unit that detects a line of sight of a user wearing the head-mounted display apparatus;
- and
- a processor that functions as:
- a distance-specific image generation unit that generates distance-specific display images for displaying, on the virtual screens, a display object representing an object to be displayed present between two focal lengths next to each other of the plurality of focal lengths;
- a display controller that displays each of the generated distance-specific display images on the virtual screen;
- and
- a point-of-fixation distance calculation unit that calculates, from the detected line of sight, a point-of-fixation distance that is a distance between the user and a point of fixation upon which the user fixates, wherein
- the distance-specific image generation unit generates the distance-specific display images by utilizing the calculated point-of-fixation distance, and
- the display controller causes each of the virtual screens corresponding to the point-of-fixation distance to display the distance-specific display images generated by utilizing the point-of-fixation distance.
A head-mounted display apparatus, comprising:
- a display that functions as a display unit that displays each of virtual screens that is set to each of a plurality of predetermined focal lengths;
- a sensor that functions as a line-of-sight detection unit that detects a line of sight of a user wearing the head-mounted display apparatus;
- and
- a processor that functions as:
- a distance-specific image generation unit that generates distance-specific display images for displaying, on the virtual screens, a display object representing an object to be displayed present between two focal lengths next to each other of the plurality of focal lengths;
- a display controller that displays each of the generated distance-specific display images on the virtual screen;
- and
- a point-of-fixation distance calculation unit that calculates, from the detected line of sight, a point-of-fixation distance that is a distance between the user and a point of fixation upon which the user fixates, wherein
- the display controller displays a continuous display object that is the display object representing an object to be displayed present continuously over a plurality of the focal lengths, onto the virtual screen corresponding to a focal length closest to the point-of-fixation distance, of the plurality of the focal lengths.
A display control method for a head-mounted display apparatus including a display that displays each of virtual screens that is set to each of a plurality of predetermined focal lengths, the method comprising:
- generating distance-specific display images for displaying, on the virtual screens, a display object representing an object to be displayed present between two focal lengths next to each other of the plurality of focal lengths;
- displaying each of the generated distance-specific display images on the virtual screen;
- detecting a line of sight of a user wearing the head-mounted display apparatus;
- calculating, from the detected line of sight, a point-of-fixation distance that is a distance between the user and a point of fixation upon which the user fixates, wherein the generating of the distance-specific display images is by utilizing the calculated point-of-fixation distance;
- and
- causing each of the virtual screens corresponding to the point-of-fixation distance to display the distance-specific display images generated by utilizing the point-of-fixation distance.
