Circular Scroll Bar for Mobile Terminal Edge Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for mobile terminals face challenges in providing an efficient and intuitive user interface for various functionalities, particularly in managing and navigating data on limited screen spaces.
Innovation Solution
A mobile terminal with a circle type display and a method for controlling it, where a scroll bar is generated at the edge of the display in response to user inputs, allowing for scrolling, zooming, and menu navigation through touch-and-drag, touch-hold-and-drag, and simultaneous touch inputs, enhancing user interaction and data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional display interface is used on a mobile terminal with limited screen space, then the device structure remains simple, but the user interface efficiency and data navigation capability deteriorate
Solution Approach 1:
The patent transforms the traditional linear scroll bar into a circular scroll bar that operates in a rotational dimension. The scroll bar is positioned along the circumferential direction of the circular display, allowing users to scroll by rotating the display or dragging along the circular edge. This dimensional change enables more efficient data navigation on limited screen space while maintaining a relatively simple display structure.
Solution Approach 2:
The patent implements dynamic behavior in the circular scroll bar through multiple touch input modes. Different touch operations (single touch, multi-touch, drag distance, rotation direction) dynamically change the scrolling behavior, zoom level, and menu navigation. This dynamic response to user input enhances interface efficiency without requiring complex hardware structures.
2Length of moving object
If the screen size of mobile terminal is reduced to improve portability, then the device becomes more portable, but the data navigation and menu control efficiency deteriorates
Solution Approach 1:
By transitioning from linear to circular scrolling along the display circumference, the patent enables more data to be accessed within the limited screen area. The circular arrangement allows users to navigate through lists and menus by rotating along the edge of the display, effectively utilizing the available screen real estate and maintaining high navigation efficiency despite reduced device size.
Solution Approach 2:
The circular scroll bar serves multiple functions: scrolling through lists, zooming in/out, navigating menus, and controlling playback. This multi-functionality compensates for the reduced screen size by providing comprehensive data navigation capabilities within a compact form factor, thereby maintaining productivity despite smaller device dimensions.
3Adaptability or versatility
If multiple functions are integrated into the display interface to improve functionality, then the user interaction capability improves, but the interface complexity increases
Solution Approach 1:
The circular scroll bar is designed as a universal control element that handles multiple operations through different touch input patterns. Single touch rotates the display, multi-touch enables zooming, drag distance controls scrolling speed, and rotation direction changes navigation direction. This multi-functional design enhances user interaction capability while maintaining a unified, relatively simple interface structure rather than adding separate controls for each function.
Solution Approach 2:
The display interface automatically adapts to user needs by detecting touch input patterns and providing appropriate functions. The system self-adjusts between scrolling, zooming, and menu navigation based on the user's touch behavior without requiring complex configuration or mode switching, thereby improving versatility while keeping the interface relatively simple and intuitive.
