Virtual Space Moving Apparatus With Variable Movement Ratios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face limitations in moving freely within virtual spaces due to the constraints of their real-world movement area in conventional virtual reality systems.
Innovation Solution
A virtual space moving apparatus and method that utilizes a 3D camera, processor, and GUI to create a virtual object corresponding to real objects, with adjustable detection areas allowing for varied movement ratios, enabling users to move freely in virtual spaces without real-world limitations by setting accelerated-movement regions with different movement ratios.

Engineering Contradiction Analysis
1Adaptability or versatility
If a one-to-one mapping between real space and virtual space is used, then the user can move continuously in the virtual space corresponding to real space movement, but the user's movement in virtual space is limited by the size of the real space
Solution Approach 1:
The real space is divided into multiple detection areas (first detection area, second detection area, third detection area) with different movement ratios. When the user moves within the first detection area, the virtual object moves by a first movement distance; when moving within the second detection area, the virtual object moves by a second movement distance greater than the first; and when moving within the third detection area, the virtual object moves by a third movement distance greater than the second. This segmentation allows the user to experience expansive virtual space beyond the physical real space boundaries.
2Adaptability or versatility
If the virtual space is expanded beyond real space boundaries, then the user can move more freely in virtual space, but the mapping relationship between real space and virtual space becomes complex
Solution Approach 1:
Different detection areas are assigned different movement ratios to achieve local optimization. The first detection area has a first movement ratio, the second detection area has a second movement ratio greater than the first, and the third detection area has a third movement ratio greater than the second. This allows the system to manage complexity by applying different mapping rules to different local regions rather than using a single complex global mapping.

AI summary
Provided are virtual space moving apparatus and method. A virtual space moving apparatus includes a 3D camera to capture real space; a display; and a processor to display a virtual space, implement a virtual object corresponding to an actual object in an actual space, and display virtual object at a specific position in virtual space, set a first detection area adjacent to an initial position of actual object and a second detection area spaced from initial position of actual object and surrounding first detection area, when actual object is moved by a first distance in first detection area outwards from initial position, move virtual object by first virtual movement distance, and when actual object is moved by first distance in second detection area outwards from a boundary between first detection area and second detection area, move virtual object by a second virtual movement distance greater than first virtual movement distance.
