Context-Aware XR Widget Placement for Peripheral Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR devices face issues such as information overload, user discomfort, attention tunneling, and occlusion of real-world features due to inappropriate placement of virtual content, particularly in continuous or extended use scenarios.
Innovation Solution
The implementation of dynamic virtual content placement techniques, including orientation-guided, world-aligned, and object-aware placement, which utilize user context and sensor data to accurately position virtual content widgets without causing distractions or occlusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If virtual content is placed in prominent positions to ensure visibility, then information delivery is improved, but user discomfort and occlusion of real-world features increase
Solution Approach 1:
The system applies different placement strategies to different regions of the field of view. Virtual content is placed in peripheral regions rather than central regions, creating local quality differences in information density and visual prominence. This allows information to be delivered without dominating the user's central vision, thereby reducing discomfort and occlusion while maintaining accessibility.
Solution Approach 2:
The system transitions from two-dimensional screen-based placement to three-dimensional spatial placement within the field of view. By utilizing depth, angle, and spatial position, the system can place virtual content in peripheral or background regions that do not occlude real-world features, effectively adding spatial dimensions to the information delivery strategy.
2Loss of information
If multiple virtual content elements are displayed simultaneously to provide comprehensive information, then information completeness is improved, but information overload and user distraction increase
Solution Approach 1:
The system segments virtual content into multiple discrete elements distributed across different spatial locations in the field of view. Instead of presenting all information in a single concentrated area, content is divided and placed in peripheral regions, allowing users to process information gradually without feeling overwhelmed by a dense information cluster.
Solution Approach 2:
The system employs selective placement of virtual content based on user context, activity, and environmental factors. Rather than displaying all possible information simultaneously, the system strategically places only relevant content in appropriate locations, providing sufficient information without excessive detail that would cause overload.
3Adaptability or versatility
If virtual content is placed to maximize immersion, then XR experience quality is improved, but safety concerns and occlusion of real-world features worsen
Solution Approach 1:
The system creates local quality differences by placing immersive virtual content in peripheral regions while keeping central vision clear for real-world awareness. This spatial differentiation allows immersion to be maintained through engaging peripheral content without compromising safety, as the user's central focus remains on the real environment.
Solution Approach 2:
The system performs preliminary assessment of the environment and user context before placing virtual content. By evaluating safety constraints, real-world features, and user activity in advance, the system can position immersive content in locations that enhance the XR experience without creating safety hazards or occluding critical real-world elements.

AI summary
Examples described herein relate to the dynamic placement of virtual content, such as virtual content widgets, to provide an extended reality (XR) experience. An XR device accesses sensor data from one or more sensors. User context associated with a user of the XR device is determined based on the sensor data. A virtual content widget is identified for presentation to the user. A widget location is selected based on the user context. The XR device causes presentation, via a display component, of the virtual content widget at the widget location.
