Touch Display Content Shrinkage and Orientation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manipulating user interface objects on touch-sensitive surfaces are cumbersome, inflexible, and inefficient, particularly neglecting the physical orientation of the surface and its impact on user interface elements, leading to increased cognitive burden and power consumption in battery-operated devices.
Innovation Solution
A method and device that utilize a touch-sensitive display to play content in full-size mode, detect gestures to shrink content while maintaining aspect ratio, and display related information and video content icons, allowing users to select different content, while adapting to orientation changes by continuing content playback in full-size mode when rotating from portrait to landscape orientation.

Engineering Contradiction Analysis
1Ease of operation
If existing methods manipulate user interface objects on touch-sensitive surfaces without considering physical orientation, then the manipulation process is simple, but the cognitive burden on users increases and task completion time lengthens
Solution Approach 1:
The user interface dynamically adapts its layout and interaction methods based on the detected physical orientation of the touch-sensitive surface. The system transitions between different interface configurations (portrait mode vs. landscape mode) to optimize manipulation efficiency for the current orientation, reducing cognitive burden and task completion time.
Solution Approach 2:
The system changes key interface parameters including element positioning, sizing, and arrangement based on orientation detection. When the physical orientation changes, the interface recalculates and repositions user interface objects to maintain optimal interaction characteristics, thereby improving ease of operation without increasing task completion time.
2Ease of operation
If the user interface does not adapt to physical orientation changes, then the interface design is simple, but power consumption increases due to inefficient interactions
Solution Approach 1:
The interface continuously monitors physical orientation and dynamically adjusts its configuration accordingly. This adaptive behavior enables more efficient user interactions that require fewer操作步骤 and reduce the time the display and processor remain active, thereby conserving battery power in portable devices.
Solution Approach 2:
The system automatically detects orientation changes and autonomously reconfigures the user interface without requiring user intervention. This self-adapting behavior optimizes interaction efficiency and reduces unnecessary processing, leading to lower power consumption while maintaining ease of operation.
3Productivity
If the user interface considers physical orientation and adapts layout accordingly, then user interaction becomes more efficient, but the device complexity increases
Solution Approach 1:
The interface employs dynamic adaptation mechanisms that automatically adjust layout and interaction elements based on detected physical orientation. This enables faster task completion through optimized interface configurations while managing complexity through systematic orientation-based rules and automated detection protocols.
Solution Approach 2:
The system systematically changes interface parameters (positioning, sizing, arrangement) based on orientation state. By implementing structured parameter transformation rules that map orientation states to specific layout configurations, the system achieves high productivity while controlling complexity through predictable, rule-based adaptations.
4Manufacturing precision
If content display maintains aspect ratio during gesture manipulation, then content quality is preserved, but the flexibility of layout adjustment is reduced
Solution Approach 1:
The system dynamically adjusts content display between two states: maintaining aspect ratio during gesture manipulation to preserve quality, and adapting layout flexibility when orientation changes occur. This dynamic switching enables the interface to optimize for both content quality and layout adaptability depending on the operational context.
Solution Approach 2:
The interface changes display parameters conditionally: preserving aspect ratio parameters during user gestures to maintain content quality, while allowing layout parameters to become more flexible when orientation changes are detected. This parameter switching strategy balances content quality preservation with layout adaptability needs.

AI summary
A multifunction device with a touch-sensitive display: plays a first piece of content in a full-size mode on the display at a predefined aspect ratio; while playing the first piece of content on the display in the full-size mode, detects a first gesture on the display; and, in response to detecting the first gesture: shrinks the playing of the first piece of content to a first region of the display while keeping the predefined aspect ratio and displays information related to the first piece of content in a second region of the display.
