Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual representation technologies lack intuitiveness in operation, requiring complex operations and limited field of view for controlling mobile objects in real spaces.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed field of view is used in virtual representation, then the system structure is simple, but the operability and user interaction flexibility deteriorate
Solution Approach 1:
The patent implements dynamic control of the field of view by allowing the virtual viewpoint to move freely within the three-dimensional space rather than being fixed. The system dynamically adjusts the visible range based on the virtual viewpoint position, enabling users to explore different areas by manipulating the viewpoint, thus improving operability without requiring complex additional hardware
Solution Approach 2:
The patent introduces a virtual viewpoint dimension that operates within the three-dimensional space. By adding this control dimension, users can navigate and interact with the virtual representation from multiple perspectives, significantly enhancing operability and user interaction flexibility while maintaining relatively simple system structure
2Ease of operation
If complex operations are required to control mobile objects, then precise control is achieved, but ease of operation deteriorates
Solution Approach 1:
The patent creates a virtual copy of the three-dimensional space that mirrors the real environment. Users interact with this virtual copy through simple viewpoint manipulation, which automatically translates to appropriate control actions in the real space. This copying approach simplifies operations while maintaining precise control, as the complex control logic is embedded in the virtual representation system rather than requiring complex user operations
3Ease of operation
If the field of view is limited in virtual representation, then processing requirements are reduced, but intuitiveness and user interaction deteriorate
Solution Approach 1:
The system implements a dynamic field of view that expands and contracts based on the virtual viewpoint position and user interaction. Rather than using a fixed limited field of view, the system dynamically adjusts the visible range, allowing users to see more of the three-dimensional space when needed while maintaining efficient processing by only rendering what is currently visible from the active viewpoint

AI summary
[Object] To provide an information processing method, a program, and a system that are capable of exhibiting high intuitiveness in operation.[Solving Means] In order to achieve the above object, an information processing method according to an embodiment of the present technology is an information processing method executed by a computer system, the method including controlling setting of a virtual viewpoint of a user with respect to a real space and setting of an operable range in which an operation relating to the real space can be executed by the user with respect to the real space. This makes it possible to exhibit high intuitiveness in operation. Further, the operable range is set to the range within the reach of a controller held by the user, that is, the range within the reach of the user, and thus the physical spatial perception ability of a human can be used.
