Equalizer Slider Visual Feedback via Color and Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia players with audio equalizers display amplifier adjustments only through numeric values, making it non-intuitive for users to adjust audio signal amplifying values at different frequency bands, leading to reduced user convenience and efficiency.
Innovation Solution
A method and device that adjust the displaying manner of adjustment controls on an equalizer interface based on the slider's position, including color, brightness, and size changes, allowing users to intuitively sense changes in audio signal amplifying values through visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If numeric values are used to display amplifier adjustments, then the device complexity is reduced, but the ease of operation deteriorates because users cannot intuitively sense changes in audio signal amplifying values
Solution Approach 1:
The patent applies color changes to the slider and slide channel to represent different amplifying values. As the slider moves along the slide channel, the color transitions from cool tones (e.g., blue) for lower amplifying values to warm tones (e.g., red) for higher amplifying values. This provides intuitive visual feedback to users about the amplifying value without requiring numeric displays, thereby improving ease of operation while maintaining acceptable device complexity.
Solution Approach 2:
The patent transitions from one-dimensional numeric display to multi-dimensional visual representation by incorporating color, brightness, and size variations. The slider and slide channel are rendered with varying colors and intensities that correspond to different amplifying values, creating a visual spectrum that users can intuitively interpret. This dimensional enrichment allows users to sense changes in amplifying values through visual cues rather than numeric changes.
2Ease of operation
If visual cues such as color and brightness changes are implemented, then the ease of operation improves by making amplifying value changes more intuitive, but the device complexity increases
Solution Approach 1:
The patent implements color changes in the slider and slide channel to indicate different amplifying values. The color transitions smoothly as the slider moves, providing continuous visual feedback that helps users intuitively understand the amplifying value changes. This approach significantly improves user adjustment efficiency by replacing abstract numeric values with intuitive color gradients.
Solution Approach 2:
The patent employs dynamic visual properties that change in real-time as the slider moves. The brightness, color intensity, and size of the slider and slide channel are dynamically adjusted based on the current amplifying value. This dynamic behavior provides immediate visual feedback, enhancing user understanding of the amplifying value changes without requiring complex numeric displays.
3Ease of operation
If the displaying manner is adjusted according to slider position, then the ease of operation improves through intuitive visual feedback, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The patent implements visual feedback mechanisms where the slider and slide channel's appearance (color, brightness, size) changes in response to the slider's position. This feedback loop provides users with immediate visual information about the amplifying value, enabling intuitive adjustment. The feedback is generated by processing the slider position data and applying corresponding visual transformations, which enhances ease of operation while managing processing complexity through efficient rendering techniques.

AI summary
A method and device for displaying a control belongs to the field of audio adjustment. At least one adjustment control is displayed on an equalizer displaying interface, with the adjustment control including a slide channel and a slider, and with the adjustment control being used for adjusting an audio signal amplifying value at a frequency band according to a position of the slider on the slide channel. The position of the slider on the slide channel is obtained when a sliding signal of the slider is received. A displaying manner of the adjustment control is adjusted according to the position of the slider.
