Message-Linked Virtual Object Appearance Control Across Virtual Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the ability for a sender to control whether a virtual object's appearance changes in a recipient's display, limiting the server's capability to determine such changes.
Innovation Solution
A display control apparatus with a generator to create virtual objects and a setter to manage appearance changes based on the recipient's virtual space type, allowing the sender to decide if and how the appearance of the virtual object is altered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the appearance of a virtual object is changed in accordance with a request from the recipient user, then the recipient can customize the display to their preference, but the sender loses control over whether the appearance change is permitted
Solution Approach 1:
The patent introduces a server as an intermediary between the sender and recipient. The server receives the virtual object from the sender, determines whether to permit appearance changes based on the virtual space type, and then provides the virtual object to the recipient. This intermediary structure enables the sender to maintain control while still allowing appearance customization when appropriate.
Solution Approach 2:
The patent changes the parameter of control authority from the recipient to the sender by introducing a permission determination mechanism. The server determines whether to permit appearance changes based on the type of virtual space (e.g., VR space vs. AR space), thereby controlling the parameter of appearance customization capability.
2Ease of operation
If the sender controls whether appearance changes are permitted, then the sender maintains authority over the virtual object, but the system becomes more complex
Solution Approach 1:
The server automatically determines whether to permit appearance changes based on the type of virtual space without requiring manual intervention from the sender. The system self-services the permission determination function, simplifying the control mechanism while maintaining sender authority.
Solution Approach 2:
The server performs preliminary determination of whether to permit appearance changes before providing the virtual object to the recipient. This preliminary action is based on the virtual space type information received from the recipient device, streamlining the control process.
3Adaptability or versatility
If appearance changes are permitted in all virtual spaces, then the virtual object can adapt to different environments, but inappropriate changes may occur in VR spaces where the original appearance should be maintained
Solution Approach 1:
The patent applies different quality characteristics to different virtual space types. In VR spaces, the original appearance is maintained to ensure consistency and reliability. In AR spaces, appearance changes are permitted to enable environmental adaptation. This local differentiation resolves the contradiction between adaptability and reliability.

AI summary
A display control apparatus includes a generator configured to generate a virtual object to be placed in a first virtual space visually recognized by a user who is a sender of a message, the virtual object being related to the message; and a setter configured to set whether to permit a change in an appearance of the virtual object to be displayed in a second virtual space visually recognized by a user who is a recipient of the message.
