Audio Apparatus Display Form Deviation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio apparatuses struggle to provide clear visual feedback when the operation position deviates slightly from the prescribed value, making it difficult for users to notice deviations in settings such as sound image localization and sound volume.
Innovation Solution
The audio apparatus employs a controller that changes the display form uniformly when the parameter setting value deviates from the prescribed value, regardless of the amount of deviation, using distinct highlighted displays for left and right deviations in sound image localization and different color schemes for sound volume settings, ensuring easy visual confirmation of deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display color or lightness of the index is gradually changed according to the amount of deviation from the prescribed value, then the display provides continuous visual feedback, but when the deviation is small the change is too subtle for the user to notice
Solution Approach 1:
The patent applies color changes by switching the display color between a first color (when parameter setting value coincides with prescribed value) and a second color (when deviated). This binary color switching provides clear visual feedback that is easily detectable even for small deviations, resolving the issue where gradual color changes were too subtle to notice.
Solution Approach 2:
The patent changes the display parameter (color) discontinuously rather than gradually. When the parameter setting value deviates from the prescribed value, the display color switches from the first color to the second color. This parameter change approach ensures that even small deviations produce a noticeable visual change, improving deviation detection sensitivity.
2Measurement precision
If the display provides detailed information about small deviations, then measurement precision improves, but the display complexity increases
Solution Approach 1:
The patent uses a simple binary color switching mechanism instead of complex gradual changes or multiple display elements. The display shows either the first color (coincidence) or the second color (deviation), providing clear precision feedback while maintaining minimal display system complexity.

AI summary
An audio apparatus is disclosed which allows a user to easily visually confirm deviation of an operation position from a prescribed value even when the deviation is small. The audio apparatus includes an operator that operates an audio signal, a display that displays a relationship between a parameter setting value according to an operation of the operator and a prescribed value, and one or more processors that change a display form of the display. The one or more processors cause, when the parameter setting value is deviated from the prescribed value, display with a display form different from that when the parameter setting value coincides with the prescribed value, regardless of an amount of the deviation.
