Map View Transition Mechanism for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Not all mobile devices have the processing power or high-speed connections to efficiently transition between top-down map views and street-level views, limiting their ability to display panoramic images and handle distant locations effectively.
Innovation Solution
A method that uses a processor to modify the map view by tilting and zooming it, creating a transition from a top-down to a street-level perspective by stretching the map image, adding a horizon line, and animating the tilt, allowing for the display of street-level views without requiring high-end processors or fast internet connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional transition methods (dragging icons, Google Earth-style transitions) are used, then seamless transitions between map and street-level views are achieved, but high processing power and high-speed connections are required
Solution Approach 1:
The patent extracts and removes the complex transition rendering logic from the mobile device to the server. The server generates pre-processed transition images by combining map data and street-level imagery, then transmits these ready-to-display images to the device. This eliminates the need for the device to perform complex real-time rendering operations.
Solution Approach 2:
The transition images are prepared in advance by the server before being transmitted to the mobile device. The server performs the computationally intensive task of generating transition frames that combine map and street-level views, so that when the device receives them, the work is already complete and no heavy processing is needed during the actual transition.
2Loss of information
If traditional transition methods are used, then panoramic street-level views are displayed, but high-speed internet connections are required to download additional satellite images
Solution Approach 1:
The server pre-generates transition images by combining map data and street-level imagery before transmission. This preliminary processing ensures that all necessary visual information is prepared in advance, eliminating the need for the device to download additional satellite images during the transition moment.
Solution Approach 2:
The patent merges map data and street-level imagery into unified transition images on the server side. By combining these data sources beforehand, the system ensures that both map context and street-level details are available in a single integrated image, eliminating the need for separate downloads.
3Ease of operation
If complex transition rendering is performed on mobile devices, then seamless transitions are achieved, but battery consumption increases and performance is compromised
Solution Approach 1:
The patent extracts the energy-intensive transition rendering task from the mobile device and relocates it to the server. The device only needs to receive and display pre-generated images, which consumes minimal battery power compared to performing complex real-time rendering operations.
Solution Approach 2:
By preparing transition images in advance on the server, the system eliminates the need for the mobile device to perform computationally intensive operations during transition. This preliminary processing significantly reduces the energy consumption of the mobile device while maintaining high transition quality.

AI summary
A system and method is provided for displaying a transition between a map and a street level image. In one aspect, the display on a mobile device transitions from a top-down view of a map to a street-level view of an image, such as a panoramic image, such that the mobile device uses the currently stored map image to perform a tilt and zoom transition.
