Viewpoint Control Technology for HMDs

This patent pertains to viewpoint control technology in virtual spaces using head-mounted displays. It enables changes to the viewpoint position according to user operations while generating images of the virtual space while maintaining the gaze direction. The viewpoint position is set on a sphere and displayed as a marker on the screen, allowing for intuitive operation and an immersive experience.

• Technology for setting the viewpoint position on a sphere
• Technology for displaying the viewpoint position as a marker
• Changing the viewpoint while maintaining the gaze direction

In conventional head-mounted displays, when users change their viewpoint within a virtual space, the gaze direction tends to become unstable, presenting a problem of non-intuitive operation. Additionally, the movement of the viewpoint was often unclear to users, which could detract from the sense of immersion. This led to a decrease in the entertainment value of games, preventing users from enjoying them fully.

This patent allows for dynamic changes to the viewpoint position based on user operations while maintaining the gaze direction, enabling intuitive operation within the virtual space. The viewpoint position is set on a sphere and displayed as a marker within the user's screen, making the movement of the viewpoint clearer and enhancing the sense of immersion. This improves the entertainment value of games.

• Technology that allows dynamic changes to the viewpoint position
• Ability to move the viewpoint while maintaining the gaze direction
• Technology that indicates viewpoint movement to the user
