Dynamic Virtual Camera Allocation to Balance User Control and Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual space provision systems face high processing loads and reduced user convenience due to a large number of individual virtual cameras, which are controlled by multiple users, leading to suboptimal user experience and increased system load.
Innovation Solution
A virtual space provision system that dynamically associates terminals with either a first camera, whose position or direction is user-operable, or a second camera, whose position and direction are independent of user operation, based on the number of terminals detected, to manage user convenience and reduce processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual virtual cameras are provided for each terminal to allow user control, then user convenience is improved, but processing load increases significantly
Solution Approach 1:
The system dynamically switches between first camera mode (user-controlled) and second camera mode (system-controlled) based on the number of connected terminals. When user count is low, individual first cameras are provided for user control. When user count exceeds a threshold, the system transitions to using shared second cameras to reduce processing load.
Solution Approach 2:
The system changes the operational parameters of virtual cameras based on user count. First cameras have parameters that respond to user operations (position, direction control enabled), while second cameras have fixed parameters independent of user operations. This parameter change allows the system to adapt between user convenience and processing load requirements.
2Power
If common virtual camera is shared among multiple users, then processing load is reduced, but user convenience deteriorates
Solution Approach 1:
The system segments virtual cameras into two distinct types: first cameras dedicated to individual user control and second cameras for shared system control. This segmentation allows the system to provide user-controlled cameras when needed while using shared cameras to reduce load when appropriate.
Solution Approach 2:
Second cameras serve multiple terminals simultaneously, providing a universal viewing experience for multiple users. This multi-functionality allows the system to reduce processing load by having one camera serve many users instead of requiring individual cameras for each terminal.
3Adaptability or versatility
If the number of virtual cameras is increased to serve more terminals, then user coverage is improved, but system performance deteriorates
Solution Approach 1:
The system dynamically adjusts the number and type of virtual cameras based on the number of connected terminals. When user count is low, more first cameras can be provided. When user count increases, the system transitions to using fewer second cameras, maintaining adaptability while preserving system performance.

AI summary
A server is a virtual space provision system that outputs an image generated based on a virtual space where a virtual camera is provided to a plurality of clients, and includes: an association determination unit configured to associate each of the clients with either a first camera, at least one of the position or direction of which corresponds to an operation from the client, or a second camera, the position and direction of which are independent of the operation from the client, based on the number of clients detected by a detection unit; a rendering unit configured to generate an image of the virtual space seen from the first camera or the second camera; and an output unit configured to output the image generated by the rendering unit to the client based on the association by the association determination unit.
