Wearable VR Device Adaptive Safe Zone Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR glasses struggle to allow users to safely perform motions for controlling VR content without disrupting immersion, as the size of the safe zone often conflicts with the space required for user motions.
Innovation Solution
A wearable electronic device that adaptively adjusts the size of the space necessary for user motions by setting a scale value based on the first space required for avatar motions and a second safe space, allowing the device to determine the size of the avatar's motion accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size of the safe zone is increased to allow larger user motions, then user safety is improved, but the immersion in VR content is disrupted
Solution Approach 1:
The patent applies dynamics by making the safe zone size adjustable and adaptive rather than fixed. The system dynamically modifies the safe zone boundaries based on the specific VR content being displayed, allowing the zone to expand or contract as needed. This enables the safe zone to adapt to different motion requirements of various VR applications, maintaining user safety while preserving immersion when possible.
Solution Approach 2:
The patent changes the parameter of safe zone size based on the VR content characteristics. By analyzing the motion requirements of the displayed VR content and adjusting the safe zone dimensions accordingly, the system optimizes the balance between safety and immersion. This parameter adjustment allows the safe zone to be larger when the content requires extensive motion and smaller when the content is less demanding.
2Ease of operation
If the size of the safe zone is decreased to maintain immersion, then immersion in VR content is improved, but user safety is compromised
Solution Approach 1:
The system dynamically adjusts the safe zone size based on real-time analysis of VR content motion requirements. When the content demands limited motion, the safe zone is reduced to maintain immersion, while safety is preserved through continuous monitoring and adaptive adjustment. This dynamic approach allows the system to optimize immersion without permanently compromising safety.
Solution Approach 2:
The patent modifies the safe zone parameter based on the specific VR content being displayed. By changing the safe zone size to match the motion requirements of the content, the system achieves better immersion while maintaining adequate safety margins. This parameter adaptation ensures that the safe zone is neither excessively large nor unnecessarily small.
3Device complexity
If the safe zone is set to a fixed size, then device complexity is reduced, but the system cannot adapt to different VR content requirements
Solution Approach 1:
The patent implements self-service by enabling the system to automatically determine and adjust the appropriate safe zone size based on the VR content being displayed. The device analyzes the motion requirements of the content and configures the safe zone autonomously without requiring manual intervention from the user or complex pre-programming for different scenarios.
Solution Approach 2:
The system automatically changes the safe zone parameter based on the characteristics of the VR content. By analyzing motion requirements and adjusting the safe zone size accordingly, the system achieves adaptability to different VR applications while keeping the user interface simple and the overall device complexity manageable.
