Volume Display Smooths Audio Transitions via Intermediate Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volume display methods on terminal devices experience abrupt changes when there are significant variations in voice input volume, leading to a poor user experience due to sudden changes in the displayed pattern, which are not visually smooth.
Innovation Solution
A method and apparatus that acquire both current and previous volume values of an audio signal, determine intermediate values, and sequence them with corresponding display times to smoothly transition between volume values, inserting additional values at regular intervals to ensure a smooth and accurate representation of volume changes.

Engineering Contradiction Analysis
1Measurement precision
If the radius of a concentric circle is adjusted according to the size of a volume value, then a change in a volume value of a user's voice may be visually reflected in real time, but when there is a great change between two adjacent volume values, the size of a concentric circle is changed sharply, leading to poor user experience
Solution Approach 1:
The patent segments the direct mapping between volume values and circle radii by introducing intermediate volume values. When transitioning between two volume values, the system divides the change into multiple intermediate steps, each with its own intermediate volume value and corresponding intermediate circle radius. This segmentation smooths the visual transition and prevents abrupt changes, resolving the contradiction between real-time accuracy and user experience.
Solution Approach 2:
The patent introduces intermediate volume values as mediators between the original volume values. These intermediate values act as transition points that smooth the visual transition of the concentric circle radius. By using these intermediary elements, the system maintains measurement precision while avoiding sharp visual changes that would degrade user experience.
2Productivity
If the radius of a concentric circle is adjusted according to the size of a volume value, then a change in a volume value of a user's voice may be visually reflected in real time, but the displayed pattern of a volume value changes surprisingly, leading to poor user experience
Solution Approach 1:
The patent segments the volume value transition process into multiple discrete steps with intermediate values. Each intermediate volume value corresponds to an intermediate circle radius, creating a step-by-step visual transition rather than a single abrupt change. This maintains time effectiveness by providing real-time feedback while ensuring display pattern stability through controlled incremental changes.
Solution Approach 2:
The patent introduces dynamic intermediate elements (intermediate volume values and intermediate circle radii) that adapt during the transition process. The system dynamically generates these intermediate values based on the starting and ending volume values, creating a flexible yet stable transition that maintains both time effectiveness and display stability.
