Region-Based Augmented Content Anchoring for Medical Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixed reality technologies lack the ability to dynamically adjust the presentation of augmented content based on the user's viewpoint within specific regions of the physical world, leading to either overly prominent or irrelevant displays.
Innovation Solution
A region-based augmentation system that determines whether a user's viewpoint is within an anchor region and adjusts the presentation of augmented content accordingly, switching between an evident and a less evident manner based on the user's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented content is always displayed prominently, then information visibility is improved, but user distraction and ergonomic comfort deteriorate
Solution Approach 1:
The system dynamically adjusts the presentation state of augmented content between prominent and minimized based on the user's viewpoint direction relative to the anchor region. When the viewpoint is within the anchor region, content is displayed prominently; when outside, content is minimized. This dynamic adaptation resolves the contradiction by making visibility conditional rather than static.
Solution Approach 2:
The system applies different display qualities to augmented content based on spatial context. Within the anchor region, content receives high visibility treatment; outside the anchor region, content receives reduced visibility treatment. This local differentiation allows information to be prominent when needed while minimizing distraction when not in use.
2Loss of information
If augmented content is always displayed prominently, then information visibility is improved, but system complexity increases
Solution Approach 1:
The system uses dynamic viewpoint detection and conditional rendering logic to switch between display states. The processor determines whether the viewpoint is within the anchor region and automatically adjusts content presentation accordingly, providing sophisticated functionality through relatively simple conditional logic rather than complex multi-layered systems.
3Loss of information
If augmented content follows the viewpoint continuously, then information relevance is improved, but processing requirements increase
Solution Approach 1:
The system segments the physical space into an anchor region and non-anchor regions, and segments content presentation into prominent and minimized states. By anchoring content to the viewpoint only when within the anchor region, the system achieves contextual relevance without continuous processing overhead. This segmentation allows the system to process and render content selectively rather than continuously.

AI summary
A system is configured to perform operations comprising: determining that a viewpoint of a user of a display device is directed within an anchor region of a physical world containing the user while a medical procedure comprising a first operational stage and a second operational stage is performed in the physical world; directing, in response to the determination, the display device to present augmented content in an evident manner, wherein the evident manner comprises anchoring the augmented content relative to the viewpoint, such that the augmented content follows the viewpoint as the user moves the viewpoint within the anchor region; and automatically redefining, in response to the medical procedure transitioning, the anchor region from a first region to a second region, the first region being associated with the first operational stage and the second region being associated with the second operational stage.
