Virtual Reality Apparatus Spatial Mapping Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems face challenges in allowing users to efficiently explore large virtual spaces, as the mapping between real-world play spaces and virtual reality spaces often results in inaccessible areas due to spatial limitations and non-defined regions, leading to confusing teleportation mechanics and user disorientation.
Innovation Solution
A virtual reality apparatus that determines whether a requested point-of-view location is allowed by comparing real-world play space coordinates to virtual reality space coordinates, and if not, provides a compromise point-of-view location or direction-of-view orientation to ensure seamless exploration, using sensors and a processor to manage user input and spatial mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the virtual reality space is made large to provide more exploration content, then the quantity of explorable content increases, but the accessibility of areas decreases due to spatial limitations in the real-world play space
Solution Approach 1:
The virtual reality space is segmented into multiple defined regions, each accessible from specific play space locations. This allows the large virtual space to be divided into manageable zones that can be accessed independently, resolving the contradiction between large scale and accessibility.
Solution Approach 2:
A mapping system acts as an intermediary between real-world play space coordinates and virtual reality space coordinates. This mediator translates physical movements into virtual navigation, enabling access to distant virtual locations without requiring proportional real-world movement space.
2Speed
If teleportation mechanics are implemented to improve navigation efficiency, then the speed of exploration increases, but the complexity of the system increases due to coordinate mapping and validation requirements
Solution Approach 1:
The system performs preliminary validation of teleportation requests by checking whether the target virtual location and associated play space region are defined before executing the teleportation. This advance checking prevents errors and simplifies the execution phase, balancing speed with manageable complexity.
Solution Approach 2:
The system provides feedback to users when teleportation to a requested location is not permitted, indicating that the location or associated region is not defined. This feedback mechanism guides users to valid destinations while maintaining systematic control over the complexity of coordinate management.
3Reliability
If strict validation of point-of-view locations is enforced to maintain spatial consistency, then the reliability of the virtual reality presentation increases, but the ease of operation decreases due to restricted user movement
Solution Approach 1:
The system applies different validation rules to different regions of the virtual space. Defined regions with associated play space locations permit teleportation, while undefined regions do not. This localized quality control maintains spatial consistency in critical areas while allowing flexibility elsewhere.
Solution Approach 2:
The validation system dynamically adjusts its behavior based on the requested destination. Rather than uniformly restricting all movement, the system selectively permits or denies teleportation based on whether the target location and its associated region are properly defined, balancing reliability with operational freedom.

AI summary
An apparatus configured to: present a virtual reality space having at least one defined and non-defined region; control a point-of-view location and a direction-of-view orientation based on sensors configured to sense the user in a real-world play space; receive input to move by means other than said sensors; determine if the requested point-of-view location is allowed or not allowed wherein a location is not allowed if any physical locations in the play space correspond to point-of-view locations in the virtual reality space that lie within a non-defined region and if the requested point-of-view location is not allowed, determine at least one of: (i) a compromise point-of-view location; (ii) a compromise direction-of-view orientation; (iii) a compromise point-of-view location and direction-of-view orientation; (iv) a compromise physical position of the user in the real-world play space; and present the virtual reality space from/with the at least one of (i), (ii), (iii) and (iv).
