Split Screen Navigation Gesture for Trip Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable navigation devices require frequent zooming and scrolling to select multiple destinations for trip planning, making the process inconvenient and time-consuming.
Innovation Solution
A method that generates a split screen on a touch screen by circling an area and moving in a specific direction, allowing simultaneous display of a zoomed-out original picture and a zoomed-in area, enabling easier editing and reducing the time required for trip planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user operates the navigation device to zoom-in, zoom-out and scroll up/down/left/right to select each destination one by one, then the user can select destinations on the navigation map, but the process becomes inconvenient and time consuming
Solution Approach 1:
The screen is divided into multiple display areas showing different zoom levels of the map simultaneously. The first display area shows a zoomed-out view while the second display area shows a zoomed-in view of a selected region, allowing users to see both overall context and detailed destination information at the same time without repeated zooming operations
Solution Approach 2:
The patent transitions from sequential zoom operations in one dimension to a multi-dimensional display where multiple zoom levels coexist spatially on the screen. By dividing the display into multiple areas showing different magnification levels simultaneously, the system eliminates the need for repeated zoom-in/zoom-out operations
2Adaptability or versatility
If the user frequently zooms and scrolls to select multiple destinations, then the user can plan the trip route, but the operation becomes inconvenient
Solution Approach 1:
The system allows users to perform a drag gesture on the navigation map to pre-select a target area before final destination confirmation. This preliminary selection action divides the screen to show both the selected area and surrounding context, making subsequent destination selection more convenient without requiring repeated zoom and scroll operations

AI summary
A method for generating split screen is disclosed. The method includes displaying a picture on a touch screen; touching the touch screen to circle a first area of the picture and to move along a first direction after circling the first area; and displaying and zooming out the picture in a first display block of the touch screen, and displaying and zooming in the first area in a second display block indicated by the first direction.
