Wearable VR Avatar Refresh via Motion Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems face challenges in managing system burden and power consumption when providing a shared immersive environment for multiple users, particularly due to the need for high-rate frame refreshments to maintain user visibility and prevent collisions.
Innovation Solution
A wearable device and computing unit system that outputs a simulated environment, where avatars are only refreshed when a user's motion exceeds a determined threshold (height, arm length, foot length, or step length), and users are only visible within a predetermined radar range, reducing unnecessary refresh rates and system load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-rate frame refreshment is used to maintain user visibility and prevent collisions in virtual reality environment, then user immersion and safety are improved, but system burden and power consumption increase
Solution Approach 1:
The system applies partial action by selectively refreshing avatars only when motion exceeds a threshold rather than continuously refreshing all avatars. This partial refresh approach maintains necessary user visibility and collision prevention while reducing overall system burden and power consumption compared to full-rate refreshment of all virtual objects.
Solution Approach 2:
The system implements periodic action through motion-threshold-based triggering, where avatar refreshment occurs periodically only when motion events exceed the predetermined threshold. This conditional periodic refreshing maintains user safety and visibility while avoiding continuous high-rate updates that would increase power consumption and system load.
2Adaptability or versatility
If continuous avatar refreshment is performed for all users in shared virtual space, then user interaction and immersion are improved, but system burden increases
Solution Approach 1:
The system applies local quality by implementing spatial filtering through the predetermined distance threshold. Avatars are refreshed and displayed only within the wearable device's field of view and predetermined distance range, rather than uniformly refreshing all avatars in the virtual environment. This localized approach maintains necessary user interactions while reducing system burden by processing only relevant virtual objects.
Solution Approach 2:
The system performs partial action by selectively refreshing avatars based on motion threshold and spatial proximity rather than continuously refreshing all user avatars in the shared virtual space. This partial refresh strategy preserves essential user interaction capabilities within the field of view while significantly reducing system burden compared to comprehensive continuous refreshment.
