Mobile Terminal 2D to 3D Map View Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack an intuitive and convenient method for users to transition between 2D and 3D map views and to easily share or display specific areas, with limited interaction through touch inputs and no seamless integration with glasses-type mobile terminals.
Innovation Solution
A mobile terminal with a touch screen and controller that allows users to switch between 2D and 3D views by touch inputs, displays search areas in 2D maps based on 3D views, and transmits these views to external devices, with integration for glasses-type mobile terminals using gestures and wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a 2D map is displayed on the touch screen, then the map coverage area is large, but the user cannot intuitively check the 3D view of a particular direction
Solution Approach 1:
The patent enables users to switch from a 2D map view to a 3D view by performing a touch input in a first direction at a first location on the 2D map. This dimensionality change allows users to intuitively check the 3D view of a particular direction while maintaining the benefit of large map coverage area in 2D mode.
2Ease of operation
If the view is switched to 3D, then the user can check the 3D view of a particular direction, but the map coverage area displayed decreases
Solution Approach 1:
The patent provides dynamic switching between 2D and 3D map views based on user touch inputs. Users can switch to 3D view to check particular directions intuitively, then return to 2D view to see larger map coverage area, allowing flexible adaptation to different viewing needs.
3Area of stationary object
If the 2D map displays the entire map area, then the map coverage is complete, but the searched area from 3D view cannot be identified
Solution Approach 1:
When the view switches from 3D back to 2D, the patent displays a search area on the 2D map that corresponds to the area viewed in 3D. This visual indication (through color or highlight changes) allows users to identify the searched area while maintaining complete map coverage display.
4Reliability
If multiple touch inputs are required to switch between 2D and 3D views, then the operation is precise, but the ease of operation decreases
Solution Approach 1:
The patent segments the touch input into direction components. A touch input in a first direction at a first location switches to 3D view, while a touch input in a second direction (opposite to the first direction) at the same location switches back to 2D view. This segmented approach provides both precision and ease of operation.
5Adaptability or versatility
If the mobile terminal supports glasses-type devices, then the versatility increases, but the device complexity increases
Solution Approach 1:
The patent enables the mobile terminal to function as both a standalone device and as a server for glasses-type mobile terminals. The terminal can transmit 2D map data and 3D view data to external glasses-type devices, allowing one device to serve multiple functions and reducing overall system complexity.
