Touch-Sensitive Display Volume Control via Swipe Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for volume control in vehicles and mobile devices require the display of additional buttons and operating steps, which occupy valuable screen space and are not intuitive for changing volume independently of audio playback content.
Innovation Solution
A method using a touch-sensitive display unit that recognizes swipe gestures to control volume without initially displaying a volume control, allowing volume changes through a linear motion starting on any button, and enabling volume adjustment independently of audio playback content, with optional display of a volume controller for user orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a volume control is displayed on the screen before operation, then the user can control the volume, but screen space is occupied and additional operating steps are required
Solution Approach 1:
The system pre-configures the interface with multiple functional buttons that can recognize swipe gestures. When a swipe gesture is detected on any button, the system immediately activates volume control functionality without requiring preliminary display of volume controls or menu navigation, thus saving screen space while maintaining ease of operation
Solution Approach 2:
The buttons in the interface are designed to serve multiple functions: they can be tapped to execute their primary functions, or swiped to activate volume control. This multi-functionality allows the same interface elements to provide both content navigation and volume control without requiring separate dedicated volume controls, thereby conserving screen space
2Adaptability or versatility
If additional buttons are displayed for volume control, then volume adjustment is possible, but the interface complexity increases and screen space is reduced
Solution Approach 1:
The volume control functionality is merged with the existing multiple buttons in the interface. Instead of adding separate volume control buttons, the system combines volume control capability with the primary functional buttons through gesture recognition, thereby maintaining interface simplicity while achieving adaptability for volume adjustment
3Ease of operation
If volume control is integrated into audio playback menu, then volume can be controlled, but additional menu switching steps are required
Solution Approach 1:
The system prepares the buttons to recognize swipe gestures for volume control before any menu navigation is required. When the user performs a swipe gesture on any button, volume control is immediately activated without requiring the user to first navigate to an audio playback menu, thus eliminating menu switching time and enabling rapid volume adjustment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for intuitive and space-efficient volume control without occupying screen space with additional buttons, enabling rapid volume adjustments without switching to an audio playback menu, reducing unnecessary operating steps and enhancing user experience.
Implementation Method 1
a touch-sensitive display unit (1)
Implementation Method 2
Detection in front of the display unit can be achieved, for example, using a proximity sensor
