Virtual Camera Animation for 2D to 3D Map View Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map display technologies do not effectively provide visual feedback when transitioning from a two-dimensional map view to a three-dimensional map view, as the change may not be readily detectable by observers, especially when the visual differences are subtle.
Innovation Solution
Implementing a method that uses a virtual camera animation moving along a circular path to illustrate the change from a two-dimensional to a three-dimensional map view, while maintaining a stationary field-of-view, and concurrently initializing orientation sensors to enhance the visual feedback experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-dimensional map view is displayed, then the map display is simple and easy to process, but the visual difference when switching to three-dimensional view is not readily detectable
Solution Approach 1:
The patent applies color changes by transitioning the map display from a two-dimensional grayscale or muted color representation to a three-dimensional view with enhanced colors, shading, and depth information. This color transformation provides clear visual feedback that distinguishes the two view modes, allowing users to easily detect when the map view has changed from two-dimensional to three-dimensional perspective.
Solution Approach 2:
The patent implements dimensionality change by switching the map display from a two-dimensional plane to a three-dimensional perspective. This involves adding depth information, elevation data, and spatial layers to the map visualization. The transition from 2D to 3D dimensions creates obvious visual differences that make the view change readily detectable to users.
2Manufacturing precision
If subtle visual differences are used in map views, then the map display appears more realistic and detailed, but the transition between views is not easily detected
Solution Approach 1:
The patent applies preliminary action by preparing distinct visual markers, transition animations, or pre-rendered frame comparisons that highlight the differences between two-dimensional and three-dimensional views before the user completes the view switching action. This could include showing a preview of the upcoming view change or using transitional effects that emphasize the transformation, ensuring users are aware of the view mode change.
Solution Approach 2:
The patent implements feedback mechanisms that provide immediate visual confirmation when a user switches between map view modes. This could include displaying on-screen indicators, using sound effects, showing transition animations, or providing comparative visual overlays that demonstrate the difference between the current and previous view modes, ensuring users are aware of the change.
3Difficulty of detecting and measuring
If a virtual camera animation is displayed to illustrate view mode change, then visual feedback is clear and intuitive, but the device complexity increases
Solution Approach 1:
The patent applies copying by creating a virtual representation or simulation of the camera's movement and perspective changes rather than physically manipulating the display hardware. The virtual camera animation uses software-based rendering to simulate the transition, copying the essential visual characteristics of a real camera movement without the physical complexity. This allows clear visual feedback while maintaining relative simplicity through virtual rather than physical implementation.

AI summary
Methods, systems and apparatus are described to provide visual feedback of a change in map view. Various embodiments may display a map view of a map in a two-dimensional map view mode. Embodiments may obtain input indicating a change to a three-dimensional map view mode. Input may be obtained through the utilization of touch, auditory, or other well-known input technologies. Some embodiments may allow the input to request a specific display position to display. In response to the input indicating a change to a three-dimensional map view mode, embodiments may then display an animation that moves a virtual camera for the map display to different virtual camera positions to illustrate that the map view mode is changed to a three-dimensional map view mode.
