Touch-Sensitive Display Gesture Scrolling Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in efficiently navigating and interacting with information due to their small size, requiring improved scrolling mechanisms that are intuitive and do not rely on buttons or menus.
Innovation Solution
A method is introduced where gestures on the touch-sensitive display determine the scrolling mode, with the origin and direction of the gesture dictating whether page scrolling or cursor scrolling occurs, allowing seamless navigation without the need for additional controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the device size is decreased to improve portability, then portability is improved, but the display area and input space are reduced making navigation difficult
Solution Approach 1:
The touch-sensitive display allows the information itself to serve as the input mechanism. Users can directly touch and manipulate the displayed content (text, images, icons) to navigate and interact, eliminating the need for separate physical buttons or control mechanisms. This self-service approach enables effective navigation despite the reduced size of the device and display area.
2Ease of operation
If traditional buttons or menus are used for scrolling, then navigation control is provided, but the device complexity and space requirements increase
Solution Approach 1:
The patent extracts the scrolling control function from separate physical buttons or menu systems and integrates it directly into the touch-sensitive display interface. The scrolling functionality is embedded within the display itself, allowing users to interact with the display content directly without needing external or separate control mechanisms, thereby reducing device complexity.
Solution Approach 2:
The touch-sensitive display serves multiple functions: it displays information and simultaneously acts as the input control mechanism for scrolling and navigation. This multi-functionality eliminates the need for dedicated scrolling buttons or separate control interfaces, reducing overall device complexity while maintaining ease of operation.
3Area of stationary object
If the display area is reduced to improve portability, then portability is improved, but the amount of信息显示 and navigation options are limited
Solution Approach 1:
The patent implements dynamic scrolling modes that adapt to the user's interaction patterns and the displayed content. The system can switch between different scrolling behaviors (e.g., page-by-page scrolling, continuous scrolling, jump scrolling) based on the gesture characteristics and context, maximizing the utility of the limited display area while providing versatile navigation capabilities.

AI summary
A method of controlling a portable electronic device that has a touch-sensitive display includes displaying information on the touch-sensitive display, detecting a gesture on the touch-sensitive display, scrolling through the information in a first scrolling mode when the gesture is associated with a first area of the touch-sensitive display, and scrolling through the information in a second scrolling mode when the gesture is associated with a second area of the touch-sensitive display.
