Partial Map View on Virtual Floor Surface for AR Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers and device manufacturers face challenges in providing a partial map view that complements an augmented reality view without decreasing spatial immersion or occluding important information during user navigation and interaction.
Innovation Solution
A method and apparatus that determine a virtual floor surface in a perspective-based display, allowing a partial map view to be rendered on this surface, providing an alternate view of location information while maintaining spatial immersion by transitioning seamlessly between 2D and augmented reality views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a partial map view is displayed in the corner or overlaid on the panoramic view to provide spatial context, then the user's understanding of virtual positioning and orientation is improved, but the sense of spatial immersion decreases and important information is occluded
Solution Approach 1:
The patent transitions the partial map view from a 2D overlay or corner display into a 3D virtual environment by rendering it on the virtual floor surface. This dimensional transformation allows the map to provide spatial context without blocking the panoramic view, as users can look down to see the map and look forward to see the augmented reality scene, eliminating occlusion while maintaining immersion.
Solution Approach 2:
The virtual floor surface acts as an intermediary between the user and the partial map view. By placing the map on this virtual surface that exists within the augmented reality environment, the map becomes integrated into the scene rather than being a separate overlay, thus maintaining spatial immersion while providing necessary contextual information.
2Loss of information
If the partial map view is made large enough for the user to understand surroundings, then spatial context is improved, but spatial immersion decreases due to occlusion of important information
Solution Approach 1:
By rendering the map on the virtual floor surface in 3D space rather than as a 2D overlay, the map can be made sufficiently large for understanding surroundings without occluding important information. Users can simultaneously view the full panoramic scene and the map by naturally moving their viewing angle downward, eliminating the trade-off between map size and immersion.
3Ease of operation
If a 2D map abstraction is displayed to provide spatial context, then navigation understanding is improved, but spatial immersion decreases
Solution Approach 1:
The patent transforms the traditional 2D map abstraction into a 3D virtual floor surface within the augmented reality environment. This allows the map to maintain its navigational utility while being integrated into the 3D scene, reducing the dissonance between 2D representation and 3D immersion by giving the map a proper 3D context.
Solution Approach 2:
The map is selectively placed on the virtual floor surface at locations relevant to the user's current position and orientation, providing navigation information locally where needed without disrupting the overall immersive experience. The map appears only in the appropriate spatial context rather than occupying the entire view.

AI summary
An approach is provided for providing a map view that compliments an augmented reality view while a user navigates and interacts within a scene. A mapping platform determines a virtual floor surface of at least one presentation of a perspective-based display of location information. A mapping platform causes, at least in part, a rendering of a partial map view on the virtual floor surface, wherein the partial map view provides an alternate view of the location information.
