Map Tilt-Zoom Transition Control for Stable Camera Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map applications lack a seamless integration of tilt and zoom features, leading to sudden changes in camera orientation and increased user input adjustments, which affects processing efficiency and power consumption.
Innovation Solution
Implementing a combined tilt and zoom feature where the tilt angle of a virtual camera depends on the zoom level, with a specified curve that allows for smooth transitions and user-customizable tilt angles, ensuring predictable and integrated user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate tilt and zoom controls are implemented, then user customization flexibility is improved, but sudden camera orientation changes and increased user input adjustments occur
Solution Approach 1:
The patent combines tilt and zoom controls into a single integrated mechanism. When a user performs a zoom gesture, the system automatically calculates and applies the corresponding tilt angle based on a predetermined relationship, eliminating the need for separate tilt adjustments and preventing sudden camera orientation changes.
Solution Approach 2:
The system establishes a feedback loop where zoom level automatically determines tilt angle through a predetermined relationship. This feedback mechanism ensures that camera orientation changes are predictable and smooth, preventing user input adjustments by continuously coordinating zoom and tilt parameters.
2Productivity
If automatic tilt-zoom integration is implemented, then processing efficiency is improved, but device complexity increases
Solution Approach 1:
The patent uses parameter changes by establishing a predetermined relationship between zoom level and tilt angle. Instead of implementing complex real-time calculation systems, the system uses predefined parameter mappings that efficiently determine tilt angles based on zoom levels, improving processing efficiency while maintaining manageable complexity.
3Adaptability or versatility
If manual tilt adjustments are allowed at any zoom level, then user customization is improved, but power consumption increases
Solution Approach 1:
The system implements self-service by automatically managing tilt angles based on zoom levels without requiring continuous user input. The predetermined relationship between zoom and tilt enables the system to self-regulate camera orientation, reducing the processing power and energy consumption associated with manual adjustments.

AI summary
Zoom and tilt operations are performed on a map display based on a predetermined relationship between zooming and tilting that is defined by a plurality of zoom-tilt transition points. If user zoom input is received after a user has tilted the map representation to a user-selected tilt angle, a next zoom-tilt transition point in the specified relationship, in the zoom direction, is determined. The display of the map representation is then updated at a rate of tilt and zoom that is based at least in part on the user zoom input, and the difference between the next zoom-tilt transition point and the initial zoom level and the user-selected tilt angle.
