Virtual Viewpoint Control Apparatus Mode Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users, especially inexperienced ones, face difficulty in operating virtual viewpoint controls due to high freedom in virtual viewpoint operations, leading to unintended viewpoint settings.
Innovation Solution
A control apparatus that includes a display control unit for displaying a virtual viewpoint image, an identification unit for selecting between different reproduction modes, and a control unit that adjusts the virtual viewpoint's position and orientation based on user operations, with distinct responses in each mode, allowing for intuitive control in both free and player's viewpoint modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high degree of freedom is allowed in virtual viewpoint operations, then versatility of viewpoint control is improved, but ease of operation deteriorates
Solution Approach 1:
The viewpoint control is segmented into multiple reproduction modes (first reproduction mode with fixed position, second reproduction mode with position tracking, third reproduction mode with automatic positioning). Each mode handles specific viewing needs, dividing the complex control task into manageable segments that are easier to operate within each context.
Solution Approach 2:
The system dynamically switches between different reproduction modes based on user selection or system determination. The control characteristics change dynamically - in the second reproduction mode, the viewpoint position dynamically follows the object, while in the first mode it remains fixed, providing adaptive ease of operation for different scenarios.
2Adaptability or versatility
If multiple reproduction modes are provided, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The control apparatus provides multiple reproduction modes through a unified control system that handles different operation characteristics. The identification unit universally identifies which reproduction mode is selected, and the control unit universally applies the appropriate control logic, making the multi-functional system manageable despite its complexity.
Solution Approach 2:
The identification unit acts as an intermediary that receives user input and determines the appropriate reproduction mode. This intermediary layer simplifies the interface between the user and the complex multi-mode system by automatically identifying and switching between modes, reducing the burden on users to manually manage system complexity.

AI summary
A control apparatus includes a display control unit configured to display a virtual viewpoint image on a display unit, an identification unit configured to identify a selected reproduction mode from among a plurality of reproduction modes including a first reproduction mode in which a position of a virtual viewpoint corresponding to the virtual viewpoint image displayed on the display unit is determined regardless of a position of an object in an image-capturing region, and a second reproduction mode in which the position of the virtual viewpoint changes in accordance with the position of the object in the image-capturing region, and a control unit configured to change at least either one of a position and an orientation of the virtual viewpoint in response to a user operation. The change to be made in response to an identical user operation differs between the first reproduction mode and the second reproduction mode.
