Touchscreen Gesture Rotation for Screen Orientation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in designing user interfaces that allow easy interaction due to their compact size and increased functions, leading to complex key sequences and inflexible menu systems, particularly for screen rotations between portrait and landscape orientations.
Innovation Solution
A portable multifunction device with a touch-sensitive display that detects simultaneous rotation of two thumbs or a thumb within a specific angle range to switch between portrait and landscape orientations, providing a more intuitive and transparent user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional user interfaces with physical pushbuttons are used, then device functions can be accessed, but the interface becomes inflexible and requires complex key sequences that must be memorized
Solution Approach 1:
The patent applies dynamics by transitioning from static physical pushbuttons to a dynamic touch-sensitive display interface. The display can adapt its layout and respond to various touch gestures (taps, swipes, rotations) in real-time, allowing the interface to change based on user interaction rather than being fixed in advance.
Solution Approach 2:
The patent utilizes parameter changes by detecting the orientation parameters (portrait vs. landscape) through accelerometer data and automatically adjusting the display orientation parameter. This allows the interface to adapt to different holding positions without requiring users to memorize specific button sequences.
2Extent of automation
If accelerometers are used to automatically adjust screen orientation, then screen rotation is automated, but users cannot easily override the automatic orientation when desired
Solution Approach 1:
The system provides self-service by automatically detecting device orientation through accelerometers and adjusting the display accordingly. However, it also enables manual override through specific touch gestures (such as rotating two thumbs simultaneously), allowing users to take control when needed without requiring complex menu navigation.
Solution Approach 2:
The system implements feedback by continuously monitoring accelerometer data to detect device orientation and automatically adjusting the display. When a user performs a specific gesture pattern, the system provides feedback by switching to manual orientation control mode, allowing the user to override the automatic behavior.
3Adaptability or versatility
If the display supports both portrait and landscape orientations, then viewing flexibility is improved, but the input method for initiating rotation becomes non-intuitive
Solution Approach 1:
The system enables self-service orientation switching by detecting natural thumb rotation gestures. When users naturally rotate their thumbs in a sweeping motion on the touch-sensitive display, the system interprets this as a rotation command and switches between portrait and landscape orientations without requiring users to learn specific button sequences.
Solution Approach 2:
The patent replaces the mechanical pushbutton system with a touch-sensitive display that detects gesture patterns. The rotation gesture (sweeping motion with thumbs) substitutes for traditional rotation mechanisms, providing an intuitive interface that leverages natural user movements rather than requiring users to adapt to artificial control schemes.

AI summary
In accordance with some embodiments, a computer-implemented method performed at a portable multifunction device with a touch screen display includes displaying information on the touch screen display in a portrait orientation. The method also includes detecting simultaneous rotation of two thumbs in a first sense of rotation on the touch screen display, and in response to detecting the simultaneous rotation of the two thumbs in the first sense of rotation, displaying the information in a landscape orientation. In some embodiments, the method further includes detecting simultaneous rotation of the two thumbs in a second sense of rotation that is opposite the first sense of rotation, and in response to detecting the simultaneous rotation of the two thumbs in the second sense of rotation, displaying the information in a portrait orientation.
