Arc Touch Response for Small Screen Media Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touchscreen devices with small screens face difficulties in user interaction due to limited space for multi-finger operations, making it hard to perform gestures like pinch-to-zoom and precise media control, leading to inaccurate adjustments and user inconvenience.
Innovation Solution
An operation track response method that detects arc touch operations on a touchscreen, determining the radian of the arc to adjust content, such as media playback or picture zoom, without the need for physical buttons, allowing for precise control and flexible user interaction on small screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional gesture operations are used on small screens, then the device can be operated, but the precision and accuracy of control deteriorates due to limited operating area
Solution Approach 1:
The patent applies curvature by introducing arc-shaped touch operations instead of traditional linear gestures. The system detects the radian of the arc formed by user touch movements and uses this angular information to control media playback. This curved interaction model allows users to perform precise operations like fast-forward, rewind, and volume control on small screens by drawing arcs of different radians, transforming the interaction from linear displacement to angular measurement which is more space-efficient.
2Adaptability or versatility
If multi-finger operations like pinch-to-zoom are implemented, then zooming functionality is achieved, but the operating area requirement increases which is not feasible on small screens
Solution Approach 1:
The patent replaces the mechanical multi-finger pinching system with a single-finger arc-drawing system. Instead of requiring multiple fingers to pinch and spread on the screen, users simply draw arcs with a single finger, and the system calculates the radian to determine the desired zoom or media control action. This substitution dramatically reduces the physical space required while maintaining versatile functionality.
3Ease of operation
If linear sliding gestures are used for media control, then playback progress can be adjusted, but the path displacement required is too large for small screens causing inconvenience
Solution Approach 1:
The patent transforms linear sliding gestures into curved arc gestures for media control. Instead of requiring users to slide their fingers across long linear paths to adjust playback progress, users draw arcs whose radians correspond to the desired adjustment magnitude. A small arc radian produces small adjustments while a large radian produces larger adjustments, all within a compact screen area, significantly improving operation convenience on small devices.
