Context-Aware Screen Scroll Method for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile terminals with touch screens face inconvenience in scrolling through large lists due to the need for repeated drag or flick gestures, especially on devices with small screens where the screen is often covered by the finger during input.
Innovation Solution
A context awareness-based screen scroll method that detects ambient illuminance and movement using a motion sensor and camera module to set either a vision scroll mode or motion scroll mode, allowing for more intuitive scrolling based on user presence and device movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drag or flick gestures are used for scrolling, then the screen can be scrolled through list items, but the user needs to continuously perform the gesture several times to reach desired items, and the screen is often covered by the finger during input
Solution Approach 1:
The patent replaces manual drag/flick gestures with automatic scroll detection based on device movement sensors. The system detects physical movement of the terminal device and automatically scrolls the list in the corresponding direction, eliminating the need for continuous finger gestures and screen coverage.
Solution Approach 2:
The patent introduces motion sensors as an intermediary between user intent and screen scrolling. Instead of direct finger interaction, the system uses motion detection to infer scrolling intent, acting as a mediator that translates physical device movement into scroll operations without requiring finger contact with the screen.
2Adaptability or versatility
If the screen is used as both touch input unit and display unit, then integration is achieved, but the screen is often covered or blocked with the finger during input operations
Solution Approach 1:
The patent replaces manual screen interaction with automatic scroll detection based on device movement sensors. The system detects physical movement of the terminal device and automatically scrolls the list in the corresponding direction, eliminating the need for continuous finger gestures and screen coverage.
3Ease of operation
If vision scroll mode is used based on camera detection, then scrolling can be controlled without touching the screen, but the system complexity increases due to additional sensors and processing
Solution Approach 1:
The patent introduces motion sensors as an intermediary between user intent and screen scrolling. Instead of direct finger interaction, the system uses motion detection to infer scrolling intent, acting as a mediator that translates physical device movement into scroll operations without requiring finger contact with the screen.

AI summary
A context awareness-based screen scroll method is provided. The method includes detecting information about surrounding circumstances of a terminal, setting a screen scroll mode based on the surrounding circumstances, detecting occurrence of an event corresponding to the set screen scroll mode, and executing screen scroll according to the occurred event.
