3D Overlay Orientation in Panoramic Map Viewports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mapping systems face challenges in navigating and correlating user orientation within street-level views, particularly in providing a seamless 360-degree viewing experience and accurately representing spatial relationships between landmarks and map data.
Innovation Solution
A panorama viewer is integrated into a mapping system, allowing users to interact with panoramic images by rendering a three-dimensional overlay that changes orientation synchronously with the viewport, enabling 360-degree navigation and accurate representation of street-level imagery with annotations like street lines and user interface elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If street-level imagery is presented in a traditional top-down map view, then navigation is simplified, but the user loses the ability to view 360-degree panoramic images and accurately correlate orientation with real-world landmarks
Solution Approach 1:
The patent transitions from traditional 2D top-down map views to a 3D immersive panorama viewer that displays 360-degree street-level imagery. This dimensional change allows users to view the environment from street level while maintaining map integration, solving the contradiction between navigation simplicity and viewing freedom by adding a new viewing dimension rather than choosing between flat map or unrestricted panorama views
Solution Approach 2:
The panorama viewer is embedded within the mapping system interface, allowing the 360-degree view to be nested within or alongside the traditional map display. This nesting approach enables users to access immersive panoramic views while maintaining the simplified navigation context of the map, resolving the contradiction by combining both views in a hierarchical interface structure
2Adaptability or versatility
If the panorama viewer allows 360-degree viewing, then viewing freedom is improved, but it becomes difficult to correlate user orientation on the map with orientation within the street-level view
Solution Approach 1:
The system provides continuous feedback by displaying the user's current location and orientation on the map alongside the panorama view. The map shows the user's position and facing direction, while the panorama displays the corresponding real-world view, creating a feedback loop that helps users correlate their virtual orientation with actual spatial relationships and understand their position in the environment
Solution Approach 2:
The patent merges the map view and panorama view into an integrated interface where both representations coexist and reference the same spatial coordinates. This combination allows users to simultaneously see their abstract map position and the concrete street-level view, maintaining orientation correlation while enabling 360-degree viewing freedom
3Measurement precision
If annotations like street lines are added to enhance navigation, then navigation accuracy is improved, but the interface complexity increases
Solution Approach 1:
The patent applies annotations selectively to specific regions of the panorama rather than uniformly across the entire interface. Street lines and other navigational annotations are rendered only where relevant to the user's current view and navigation needs, enhancing navigation accuracy in specific areas without unnecessarily complicating the overall interface
Solution Approach 2:
The annotations are dynamically adjusted based on the user's current orientation and position within the panorama. As the user rotates or moves through the 360-degree view, the annotations update to maintain accurate spatial relationships, providing navigation precision adaptively without requiring a static complex interface design
Data Source
AI summary
A panorama viewer is disclosed which facilitates navigation from within the panorama of a larger, structured system such as a map. The panorama viewer presents a viewport on a portion of a panoramic image, the viewport including a three-dimensional overlay rendered with the panoramic image. As the orientation of the viewport within the panoramic image changes, the three-dimensional overlay's orientation in three-dimensional space also changes as it is rendered with the panoramic image in a manner that matches the change in orientation of the viewport.
