XR Dynamic Label Placement for Multi-User Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR environments face challenges in optimally displaying three-dimensional information labels that are readable and non-overlapping, particularly when multiple users view the same object from different angles, leading to confusion and impaired object visibility.
Innovation Solution
A dynamic labelling algorithm that adjusts label positions based on the user's viewpoint, object rotation, size, and distance, ensuring labels are visible and avoid overlap by projecting onto a perpendicular plane and calculating optimal display locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static label positions are used in XR environments, then implementation is simple, but labels become difficult to read and overlap when users view objects from different angles
Solution Approach 1:
The patent implements dynamic label positioning that automatically adjusts label locations based on the user's current viewpoint, camera position, and object orientation. Labels recalculate their positions in real-time as users move around objects, ensuring they remain readable and properly positioned without requiring manual intervention or complex configuration by users.
Solution Approach 2:
The system continuously monitors user position, camera angle, and object orientation to dynamically adjust label positions. This feedback loop ensures labels adapt to changing viewing conditions, maintaining optimal readability while preventing overlap with other labels or the object itself.
2Adaptability or versatility
If multiple users view the same object simultaneously, then collaborative learning is enabled, but label overlap and confusion increase
Solution Approach 1:
The patent implements user-specific label positioning where each user receives customized label placements optimized for their individual viewpoint and preferences. Multiple users can simultaneously view the same object with different label configurations, eliminating confusion while enabling collaborative learning. Each user's labels are positioned independently based on their camera position and viewing angle.
3Measurement precision
If labels are displayed close to objects, then labeling precision is high, but labels impede the view of the objects being labeled
Solution Approach 1:
The patent positions labels in three-dimensional space around objects rather than directly on them. Labels are placed at calculated positions that maintain precise association with their target objects while existing in separate spatial zones that do not obstruct the user's view of the objects. This allows accurate labeling without visual interference.

AI summary
A method for dynamically presenting labels with the same information respectively to first and second users in a common extended reality environment includes displaying a first label with first text to a first user and a different second label with second text to a second user based on the respective positions of each user in the extended reality environment. The first user sees the first label without seeing the second label and the second user sees the second label without seeing the first label.
