Display Sound Menus with Prompt Indicators for Device Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses lack an efficient method for users to conveniently select and control sound output devices, leading to burdensome operations and misunderstandings due to unavailable sound output device options in the sound setting menu.
Innovation Solution
The display apparatus provides a sound setting menu with prompt identifiers for unavailable sound output devices, allowing users to easily identify which devices can be switched to or controlled, reducing unnecessary operations and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sound setting menu displays all available sound output devices, then users have complete device options, but users experience confusion and unnecessary operations when devices are unavailable
Solution Approach 1:
The patent applies visual differentiation by changing the display state of menu items based on device availability. Available sound output devices are displayed in a normal state, while unavailable devices are displayed in a different visual state (e.g., grayed out or with different coloring), allowing users to quickly distinguish which devices can be selected without causing confusion
Solution Approach 2:
The sound setting menu is segmented into different types of items: selectable available devices and non-selectable unavailable devices. This segmentation allows the system to present comprehensive device options while clearly indicating which ones can actually be chosen, reducing unnecessary user operations
2Adaptability or versatility
If the sound setting menu shows all context menus including non-default ones, then users have complete control options, but users perform unnecessary operations on unavailable options
Solution Approach 1:
The system performs preliminary identification of non-default context menus and marks them with prompt identifiers before user selection. This preliminary action allows users to anticipate which options will lead to additional settings or changes, enabling them to make informed decisions and avoid unnecessary operations on unavailable or already-default options
Solution Approach 2:
Prompt identifiers act as intermediaries between the system's internal state (which context menus are non-default) and the user's decision-making process. These identifiers provide intermediate information that helps users understand the consequences of selecting certain options without requiring users to explore each option fully
3Loss of information
If the display apparatus provides detailed sound mode information, then users can make informed selections, but the sound setting menu becomes more complex
Solution Approach 1:
The patent applies local quality by providing different levels of information density in different parts of the menu. Prompt identifiers are selectively placed only on non-default context menus, while default menus receive simpler treatment. This localized information provision maintains clarity while still providing necessary details for informed decision-making

AI summary
Disclosed are a display apparatus and a method for sound processing. The method includes: receiving a command for setting a sound mode currently used by the display apparatus as a target sound mode; in response to the command, display a sound setting menu on the display of the display apparatus, and display a name of the target sound mode and one or more context menus corresponding to the target sound mode; and in response to at least one context menu of the one or more context menus being a non-default context menu, display a prompt identifier on the sound setting menu, wherein the non-default context menu refers to a context menu with a current sound effect parameter that is a non-default value.
