XR Visual Assistance With Dynamic Object Hiding for Safe Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual objects in extended reality environments can obscure a user's sight, posing a safety hazard when the user moves, as they may bump into real objects due to blocked vision.
Innovation Solution
An electronic device with a display, image capture device, and processor that detects user interaction and calculates distances to disable or enable virtual objects based on thresholds, switching between working and pass-through modes to maintain user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual objects are displayed in the extended reality scene, then the user can interact with virtual objects, but the user's sight is blocked and the user may bump into real objects
Solution Approach 1:
The system dynamically adjusts the visibility of virtual objects based on the user's movement state. When movement is detected, virtual objects are disabled or transparency is increased, allowing the user to see real objects clearly. This dynamic adaptation resolves the contradiction by making the system versatile during interaction while ensuring safety during movement.
Solution Approach 2:
The system periodically detects user movement and alternates between displaying virtual objects and ensuring clear vision of real objects. This periodic switching between interaction mode and safety mode allows the system to provide interaction capability when needed while preventing safety hazards during movement.
2Duration of action of stationary object
If virtual objects are displayed continuously, then the user can maintain interaction with virtual objects, but the user cannot navigate safely in the real environment
Solution Approach 1:
The display duration of virtual objects is made dynamic rather than continuous. The system monitors user movement in real-time and adjusts virtual object visibility accordingly, extending display duration during stationary interaction while reducing or disabling it during movement to ensure navigation safety.
Solution Approach 2:
The system uses feedback from movement detection to control virtual object display. When movement is detected, the system feedback loop triggers disabling or increasing transparency of virtual objects, ensuring that navigation safety takes precedence over interaction continuity.
3Adaptability or versatility
If the head mounted device displays virtual objects, then the extended reality experience is enhanced, but the user's real-world awareness is reduced
Solution Approach 1:
The system dynamically adjusts the balance between virtual and real world information based on user context. During stationary interaction, virtual objects are displayed prominently to enhance XR experience. During movement, virtual objects are disabled or made transparent to preserve real-world awareness, preventing information loss about the physical environment.
Solution Approach 2:
Different quality levels of virtual object display are applied based on spatial context. When the user is stationary and interacting with specific virtual objects, those objects are displayed with high quality. When the user moves, the display quality is reduced or objects are disabled locally, preserving awareness of the real environment without completely eliminating the XR experience.

AI summary
A method, an electronic device, and a non-transitory computer readable storage medium of visual assistance for a user in an extended reality environment are provided. The method includes: outputting an extended reality scene including a first virtual object and an interactive object; detecting the user; calculating a first distance between the interactive object and the user; and disabling the first virtual object in the extended reality scene in response to the first distance being greater than a first threshold.
