Display Control Device for Shared Virtual Space Reference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared display systems, particularly in head-mounted displays, users face challenges in efficiently referencing the same content in a virtual space, especially when the number of content pieces is large and the viewing angles between displays differ significantly.
Innovation Solution
A display control device that acquires and transmits position of interest information between displays, allowing the visual line in one display to be moved based on the position of interest in another display, thereby ensuring that users can reference the same display information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display information is arranged in a common virtual space with independent visual lines for each display, then each user can refer to different displays according to their visual line, but users cannot efficiently reference the same content when viewing directions differ significantly
Solution Approach 1:
The visual line in the virtual space is made dynamic and adjustable. Users can move the visual line to any desired position and direction in the common virtual space, allowing them to reference the same content even when their physical viewing directions differ significantly. This dynamic adjustment resolves the contradiction by providing flexibility in content selection while maintaining efficiency in referencing.
Solution Approach 2:
The system changes the parameters of the visual line (position and direction) independently of the physical display orientation. By decoupling the visual line parameters from the physical viewing direction, users can reference the same content in the virtual space regardless of their spatial arrangement, resolving the contradiction between adaptability and ease of operation.
2Quantity of substance
If the number of content pieces in virtual space is large, then more information can be displayed, but it takes time to discover content of interest among users
Solution Approach 1:
The system performs preliminary action by automatically setting the visual line to the position and direction of content of interest when users need to reference the same content. This eliminates the time-consuming process of manually searching through large amounts of content, as the visual line is pre-positioned on the desired content, resolving the contradiction between quantity of content and time to discover it.
Solution Approach 2:
The system incorporates feedback mechanisms to detect when users need to reference the same content and automatically adjusts the visual line accordingly. This feedback loop eliminates manual search time while maintaining access to a large quantity of content pieces, resolving the contradiction between content quantity and discovery time.
3Length of moving object
If display has narrow viewing angle, then device can be more compact, but it becomes difficult to reference content when visual lines are greatly different
Solution Approach 1:
The system transitions from a two-dimensional display plane to a three-dimensional virtual space. By arranging content in a common virtual space with multiple dimensions, users can reference the same content even when their physical viewing angles are narrow and differ significantly. This dimensional transition resolves the contradiction by providing spatial flexibility without requiring a wider physical viewing angle.

AI summary
A display control device is a device that performs control relating to display in a display displaying display information arranged in common in a common virtual space with another display in accordance with a visual line for each display in the virtual space based on a position or a posture in a real space for each display, the display control device includes: a position of interest information acquiring unit configured to acquire position of interest information representing a position of interest in a virtual space in the other display according to display in the other display; and a visual line moving unit configured to move the visual line in the virtual space in the display of the display on the basis of the acquired position of interest information.
