VR Interaction Coordinate Mapping for Perception-Accurate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interaction control methods in interactive interfaces, such as those used in virtual reality devices, result in perception deviations due to differing user and target coordinate systems, leading to poor user experience.
Innovation Solution
The method involves determining a first displacement vector of a first object, projecting it into user and target coordinate systems, and obtaining a second displacement vector through harmonic calculation to reconcile these systems, thereby controlling the state of a second object in the target region.

Engineering Contradiction Analysis
1Ease of operation
If the moving distance of the object in the display region is controlled according to the displacement distance of the controller or hand, then the control response is direct and simple, but perception deviation occurs due to differing coordinate systems between user and target region
Solution Approach 1:
The patent introduces a coordinate transformation mechanism as an intermediary between the user's controller displacement and the object movement in the display region. This intermediary converts the controller displacement vector from the user's coordinate system into the target region's coordinate system through projection and harmonic calculation, thereby eliminating perception deviation while maintaining direct control response.
Solution Approach 2:
The patent changes the parameter representation by transforming the displacement vector from one coordinate system to another. By projecting the displacement vector onto different coordinate axes and using harmonic calculations to combine the projections, the system adapts the movement parameters to match the target region's coordinate system, resolving the perception deviation issue.
2Measurement precision
If coordinate transformation is applied to align user and target coordinate systems, then perception deviation is reduced, but calculation complexity increases
Solution Approach 1:
The patent applies partial coordinate transformation rather than complete complex transformation. By using projection vectors and harmonic calculations only on the necessary components of the displacement vector, the system achieves sufficient coordinate alignment without performing overly complex calculations, thus balancing precision and complexity.
