Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices with touch-sensitive displays face challenges in efficiently scrolling information without unintentional scrolling, especially when limited space and multiple task windows are involved, and existing methods do not effectively integrate tilt detection for intuitive user interaction.
Innovation Solution
A method and device that detect a touch location on a touch-sensitive display and scroll information in response to a detected tilt of the device, using an orientation sensor to determine the tilt direction and scroll accordingly, allowing for intentional user control and reducing accidental scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch-sensitive display is used to provide multiple functions in limited space, then device versatility is improved, but unintentional scrolling and operation errors increase
Solution Approach 1:
The patent combines touch input and tilt detection into a unified scrolling control mechanism. The system merges the touch-sensitive display functionality with orientation sensor data to distinguish between intentional user scrolling actions and device tilting, thereby resolving the contradiction between versatile display functionality and operation accuracy.
Solution Approach 2:
The orientation sensor acts as an intermediary between the touch display and the scrolling function. By introducing tilt detection as a mediating factor, the system can differentiate between deliberate user scrolling actions and accidental device tilting, thus improving operation accuracy while maintaining display versatility.
2Productivity
If multiple task windows are displayed simultaneously to maximize information density, then productivity is improved, but user interaction complexity increases
Solution Approach 1:
The patent segments the interaction control by using tilt detection to distinguish between different user intentions. When multiple task windows are displayed, the system segments the scrolling action based on tilt direction and magnitude, allowing users to navigate between tasks more intuitively without increasing interaction complexity.
Solution Approach 2:
The system dynamically adjusts the scrolling behavior based on real-time tilt detection. When multiple task windows are visible, the scrolling mechanism adapts its response based on the detected tilt characteristics, making the interaction more intuitive and reducing complexity while maintaining high information density.
3Reliability
If tilt detection is added to improve scrolling control, then operation accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality to the orientation sensor system. The same tilt detection mechanism serves multiple purposes: it controls scrolling accuracy, distinguishes between user actions and device tilting, and provides intuitive navigation across multiple task windows. This universal approach improves scrolling control accuracy without proportionally increasing device complexity.
