Portable Device Display Format Compatibility Annotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when installing third-party application programs on portable devices, as they often cannot determine if the program is designed for their specific display specification, leading to errors or abnormal termination.
Innovation Solution
A display method for portable devices that identifies and displays annotation messages for application programs, indicating whether they match the device's display format, and provides a prohibition warning when executed, allowing users to intuitively recognize compatible applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users install third-party application programs without checking display format compatibility, then the variety of available applications increases, but execution errors and abnormal terminations occur
Solution Approach 1:
The system performs preliminary detection of display format compatibility between the application program and the portable device before the user executes the application. The processor obtains display format information from the application program and compares it with the device's display format, displaying compatibility results in advance to prevent execution errors.
Solution Approach 2:
The system provides feedback to the user regarding display format compatibility by displaying detection results. When an application program's display format does not match the portable device, the system displays a notification message informing the user of the incompatibility, enabling informed decision-making before execution.
2Loss of information
If the system displays compatibility information for all application programs, then users can identify compatible applications, but the interface complexity and information overload increase
Solution Approach 1:
The system applies local quality by displaying compatibility information selectively rather than uniformly for all applications. Compatibility notifications are displayed only for application programs that have display format incompatibility with the portable device, while compatible applications show no additional information, keeping the interface clean for users.
Solution Approach 2:
The system extracts and displays only the relevant compatibility information that users need to know. Instead of showing all application attributes, it specifically extracts and presents display format compatibility status, removing unnecessary information and focusing on the critical compatibility aspect.

AI summary
A display method and a portable device are provided. The portable device has a touch screen, and a plurality of application programs is installed in the portable device. The touch screen displays a menu interface and an object corresponding to each application program. When the object corresponding to each application program is displayed, obtain a display format supported by the application program, and determine whether the display format supported by the application program matches a first display format of the touch screen of the portable device. When the display format supported by the application program does not match the first display format of the touch screen, a first annotation message is shown on the object corresponding to the application program.
