VR Pointer Speed Control via Gaze Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR/AR systems face challenges in accurately controlling pointers within virtual spaces, particularly in adjusting movement speed based on user gaze and distance, which affects manipulation accuracy and convenience.
Innovation Solution
An electronic device with sensors, such as eye tracking and motion sensors, adjusts the movement speed of a pointer in virtual space based on the distance from the user's gaze, increasing sensitivity when farther away and reducing it when closer, to enhance manipulation precision and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pointer movement speed is increased to improve manipulation efficiency, then productivity is improved, but manufacturing precision deteriorates because it becomes difficult to accurately position the pointer when close to the target
Solution Approach 1:
The patent applies dynamics by making the pointer movement speed variable rather than fixed. The system dynamically adjusts the movement speed based on the real-time distance between the pointer and target object - moving faster when far away and slower when close, thereby resolving the contradiction between manipulation efficiency and positioning accuracy
Solution Approach 2:
The patent changes the movement speed parameter according to the distance parameter. By establishing a relationship where movement speed is a function of distance from target, the system achieves both high efficiency during traversal and high precision during final positioning, resolving the technical contradiction
2Manufacturing precision
If the pointer movement speed is decreased to improve positioning accuracy, then manufacturing precision is improved, but productivity deteriorates because it takes longer to move the pointer across the virtual space
Solution Approach 1:
The system dynamically adjusts movement speed based on contextual information (distance to target), allowing fast movement during most of the trajectory and slow movement only when necessary for precise positioning, thereby maintaining both high productivity and high precision
Solution Approach 2:
The movement process is divided into phases: a fast periodic movement phase when distant from target and a slow periodic movement phase when close to target. This periodic variation in speed allows the system to achieve both efficiency and accuracy
