Head-Mounted Display Access to Virtual Objects Across Real Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted information processing systems struggle to conveniently view and operate virtual objects present in real spaces other than the immediate surroundings of the user.
Innovation Solution
A head-mounted information processing apparatus with a camera unit, display unit, and control unit that generates and displays virtual objects associated with multiple real spaces, allowing simultaneous visualization and interaction with these objects without requiring the user to physically move to those spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual object is associated with a spatial coordinate of a real space to appear as if a real object is present, then the reality of the virtual object is increased, but the user cannot browse or operate the virtual object unless they go to the real space where it is associated
Solution Approach 1:
The patent introduces a list display as an intermediary interface that mediates between the user and virtual objects in different real spaces. The list shows thumbnails representing virtual objects and their associated real spaces, allowing users to select and access virtual objects without physically traveling to the associated real spaces. This intermediary layer resolves the contradiction by maintaining the spatial association for realism while providing convenient access through the list interface.
Solution Approach 2:
The patent creates visual copies (thumbnails) of virtual objects and their associated real spaces in a list display. These thumbnails serve as simplified representations that allow users to browse and select virtual objects from different real spaces without being present in those spaces. The copying principle enables accessibility while preserving the spatial coordination system that provides realism.
2Ease of operation
If the virtual object is displayed so as to be kept in a visual field of a user even though the visual field moves, then the user can easily access the virtual object, but it is difficult for the user to conveniently view and operate a virtual object that is present in another real space
Solution Approach 1:
The patent adds a new dimension to the display system by introducing a list view that operates alongside the immersive visual field. This list dimension provides overview information about virtual objects in different real spaces, allowing users to navigate and select objects without losing spatial context. The list display compensates for the loss of spatial information that occurs when virtual objects are kept in the visual field, enabling users to understand which real space each virtual object belongs to.
3Ease of operation
If a user goes to the real space where the target virtual object is associated to recognize it visually, then an intuitive operation system is achieved, but the user cannot browse or operate virtual objects in other real spaces without physically moving
Solution Approach 1:
The patent prepares and displays a list of virtual objects from multiple real spaces in advance, allowing users to browse and select target objects before needing to interact with them. This preliminary action eliminates the need for users to physically travel to different real spaces to access virtual objects, significantly reducing access time while maintaining the intuitive spatial association displayed in the list.

AI summary
In a head mounted information processing apparatus, a control unit includes a virtual object generation processing unit configured to generate a virtual object to be displayed by the display unit. The virtual object generation processing unit is configured to generate a first virtual object that is arranged so as to be associated with a first real space where a user exists and a second virtual object that is arranged so as to be associated with a second real space different from the first real space. The control unit is configured to cause the display to display the first virtual object and the second virtual object in accordance with virtual object display instruction information for instructing display of the first virtual object and the second virtual object, which is inputted through an operational input interface.
