VR Safety Boundary Alerting for Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual Reality (VR) systems pose safety concerns as users wearing head-mounted displays (HMDs) are unaware of their surroundings, potentially colliding with people and objects in the real world, especially when other entities, such as non-users or autonomous devices, move within the VR boundary.
Innovation Solution
A method and system that determine the location of devices within the VR environment and alert users if they enter the VR boundary, using sensors and indoor positioning systems to track devices and issue alerts through audio, visual, or haptic feedback to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VR systems provide immersive visual environments using head-mounted displays, then user immersion and engagement are improved, but user awareness of real-world surroundings deteriorates, leading to safety concerns
Solution Approach 1:
The system continuously tracks the positions of multiple devices in the VR environment and provides feedback to the user through the HMD display when another device enters the user's personal space. This feedback mechanism allows users to maintain immersion while becoming aware of surrounding entities, resolving the contradiction between immersive experience and collision risk.
Solution Approach 2:
The system introduces an intermediary layer between the user and the virtual environment - a safety monitoring system that tracks device positions and overlays warning indicators in the user's field of view. This intermediary provides real-time spatial awareness without breaking immersion, allowing users to navigate safely while maintaining the immersive VR experience.
2Object-affected harmful factors
If the VR system displays indicators of other entities in the user's field of view, then collision prevention is improved, but user immersion and presence in the virtual environment deteriorate
Solution Approach 1:
The safety indicators are displayed locally and contextually within the user's field of view rather than as global system notifications. The indicators appear only when and where relevant - when another device enters the personal space boundary - maintaining immersion by integrating safety information into the natural visual flow of the VR environment.
Solution Approach 2:
The system applies partial action by displaying safety indicators selectively rather than continuously. Indicators are shown only when another device enters the user's personal space, not throughout the entire VR session. This reduces visual clutter and maintains immersion while providing necessary safety warnings at critical moments.
3Object-affected harmful factors
If the system tracks multiple devices and provides real-time alerts, then safety monitoring is improved, but computational requirements and system complexity increase
Solution Approach 1:
Each device in the VR environment independently reports its position to the safety monitoring system, and the system automatically processes this data to determine when personal space boundaries are violated. The system serves itself by using the existing device tracking infrastructure already present in VR environments, adding safety functionality without requiring separate complex tracking systems.

AI summary
Aspects of the present disclosure relate to enhancing virtual reality safety. A virtual reality (VR) boundary associated with a VR system can be determined, the VR boundary dictating a safe play area for a VR user using the VR system. A location of a first device can be determined. A determination can be made that the location of the first device is within the VR boundary. In response to a determination that the first device is within the VR boundary, the VR user can be alerted that the first device entered the VR boundary.
