Touch Screen Orientation Locking via Peripheral Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in maintaining consistent image orientation, particularly when rotated, as existing technologies rely on accelerometer-based detection which can be unreliable in certain orientations and does not allow users to lock the image orientation manually.
Innovation Solution
The implementation of a touch input system in the peripheral zone of a touch screen display allows users to lock the image orientation using a specific gesture, independent of accelerometer inputs, ensuring the image remains in the desired orientation even when the device is rotated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If accelerometer-based detection is used to determine image orientation, then the system can automatically detect device orientation, but the detection reliability deteriorates in certain device orientations
Solution Approach 1:
The touch screen is divided into multiple selectable orientations (e.g., portrait, landscape, reverse portrait, reverse landscape), allowing the system to segment the orientation control into discrete, reliable states rather than relying solely on continuous accelerometer data that may be ambiguous in certain positions.
Solution Approach 2:
A touch input interface acts as an intermediary between the user and the orientation system, allowing manual selection of orientation when accelerometer-based automatic detection is unreliable. This mediator resolves the conflict by providing an alternative control path that bypasses the unreliable sensor data.
2Adaptability or versatility
If automatic orientation detection is implemented, then the system can adapt to device rotation, but user control over image orientation is lost
Solution Approach 1:
The system dynamically switches between automatic accelerometer-based orientation detection and manual touch-based orientation selection based on system state and user interaction. This allows the system to adapt to device rotation when appropriate while providing manual control when needed, resolving the contradiction between adaptability and user control.
Solution Approach 2:
The touch screen serves multiple functions: it acts as both a display surface and an input interface for orientation control. By integrating orientation selection directly into the touch screen interface, the system provides both automatic adaptation capabilities and manual user control through a single universal interface.
3Ease of operation
If touch input processing is added to the peripheral zone, then user control over image orientation is enabled, but device complexity increases
Solution Approach 1:
The orientation control functionality is merged with the existing touch screen interface rather than being implemented as a separate physical control mechanism. By combining orientation selection and locking capabilities with the standard touch screen, the system enables user control without adding separate hardware components, thus minimizing the increase in device complexity.
