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 that includes a camera unit, display unit, and control unit, capable of generating and displaying virtual objects associated with multiple real spaces, allowing users to visualize and interact with these objects without physically moving to those spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual objects are displayed only in the real space where the user is currently present, then the user can easily recognize and operate the virtual objects, but the user cannot access virtual objects in other real spaces without physically moving to those spaces
Solution Approach 1:
The patent introduces a new dimension of display by showing virtual objects from multiple real spaces simultaneously on a two-dimensional display screen. Instead of limiting virtual objects to only the current real space, the system creates a multi-space overview that allows users to perceive and access virtual objects across different locations without physically moving, thus resolving the contradiction between ease of operation and information loss.
Solution Approach 2:
The display screen acts as an intermediary that bridges the gap between the user's current location and virtual objects in other real spaces. By projecting virtual objects from multiple real spaces onto the display screen, the system provides a mediating view that allows users to access and operate virtual objects without needing to be physically present in the spaces where they exist, thereby improving ease of operation while maintaining visibility.
2Productivity
If the user physically moves to the real space where the virtual object is present, then the user can directly interact with the virtual object, but the user loses time and cannot access virtual objects in other spaces simultaneously
Solution Approach 1:
The patent replaces the mechanical action of physically moving the user's body between real spaces with a digital display system. Instead of requiring physical travel to access virtual objects, the system uses visual projection on a display screen to transmit information about virtual objects across different real spaces, allowing users to interact with them remotely and simultaneously, thus dramatically improving time efficiency.
Solution Approach 2:
The system performs preliminary action by pre-displaying virtual objects from multiple real spaces on the display screen before the user needs to access them. Users can view, select, and prepare to interact with virtual objects in advance from the overview display, eliminating the need for physical movement and enabling simultaneous access to multiple spaces, thereby reducing time loss.
3Adaptability or versatility
If virtual objects from multiple real spaces are displayed simultaneously, then the user can access and operate virtual objects without moving, but the display becomes complex and difficult to manage
Solution Approach 1:
The patent applies segmentation by dividing the display screen into multiple independent display areas, with each area representing a different real space. This segmentation allows virtual objects from multiple spaces to be displayed simultaneously without interfering with each other, making the complex multi-space display manageable through clear spatial organization and separate visual zones.
Solution Approach 2:
The system manages complexity by transitioning from a three-dimensional physical navigation problem to a two-dimensional display problem. By projecting virtual objects from multiple real spaces onto a two-dimensional screen with distinct display areas, the system simplifies the user interface while maintaining the ability to display multiple spaces simultaneously, thus reducing perceived complexity while preserving versatility.

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.
