Mobile Terminal Menu Visual Differentiation for Communication Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals cannot distinguish between executable and non-executable functions during a communication service blocking mode, leading to user confusion and potential missed incoming calls or messages if the user forgets to turn the device off or switch modes in restricted areas.
Innovation Solution
A method and mobile terminal configuration that displays menu items with distinguishing features such as different fonts, sizes, colors, or icons to visually differentiate between restricted and unrestricted functions, and uses location detection to enter a preliminary restricted mode, indicating the need to switch to a communication blocking mode, which can be activated with a specific command.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal enters communication blocking mode, then communication services are blocked to prevent interference with electronic equipment, but the user cannot distinguish between executable and non-executable functions leading to confusion and potential missed communications
Solution Approach 1:
The patent applies color changes to menu item text and icons to indicate their executable status. Specifically, menu items and icons for executable functions are displayed in a first color (e.g., normal color), while menu items and icons for non-executable functions are displayed in a second color (e.g., grayed out or highlighted color). This visual differentiation allows users to easily distinguish which functions can be used and which cannot during communication blocking mode, resolving the contradiction between maintaining reliable communication blocking and ensuring ease of operation.
2Reliability
If the user must manually switch to communication blocking mode, then communication interference is prevented, but the user may forget to switch modes resulting in missed calls or messages
Solution Approach 1:
The patent implements location detection functionality that automatically detects when the mobile terminal enters a restricted area and displays a prompt message to the user before communication blocking is enforced. This preliminary action gives users advance notice and opportunity to manually switch to communication blocking mode, reducing the likelihood of forgotten mode switching and missed communications while maintaining compliance with communication blocking requirements in restricted areas.
3Device complexity
If all functions are displayed uniformly in menu screens, then the interface is simple, but users cannot identify which functions are available during restricted modes
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of menu items based on their executable status. Instead of uniform display, the system applies different visual properties (color, highlighting) to specific menu items depending on whether they are executable or non-executable during communication blocking mode. This maintains the overall simplicity of the menu interface while locally enhancing specific elements to convey function availability information, thus resolving the contradiction between interface simplicity and information completeness.
