Display Control for QR Code Hiding During Key Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display units with limited size restrict information displayability, necessitating manual consultation and complicating user operations with two-dimensional codes.
Innovation Solution
A display control apparatus that differentiates between first and second attribute keys, performing distinct processing based on the presence or absence of a predetermined code on the display unit, allowing seamless integration of code display and normal operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-dimensional code is displayed on the display unit to provide manual information, then information accessibility is improved, but device complexity increases due to additional code display control
Solution Approach 1:
The system pre-loads and stores multiple two-dimensional codes corresponding to different manual sections in advance. When a user requests manual information, the appropriate pre-prepared code is immediately displayed without requiring complex real-time generation or selection processes, thus reducing device complexity while maintaining information accessibility.
2Volume of moving object
If the display unit size is small, then the device portability is improved, but information displayability deteriorates
Solution Approach 1:
The patent extracts detailed manual information from the limited display unit by generating two-dimensional codes that contain URLs or references to comprehensive manual content. Users can scan these compact codes with their terminal devices to access full manual information externally, effectively transferring the information display burden from the small display unit to external devices while maintaining portability.
3Adaptability or versatility
If normal processing is performed when a key is operated during code display, then operational functionality is maintained, but user confusion increases due to screen shifts
Solution Approach 1:
The system dynamically adjusts key response behavior based on the current display state. When a two-dimensional code is displayed, key operations trigger code hiding rather than normal processing that would cause screen shifts. This dynamic adaptation maintains operational functionality while preventing user confusion, as the system automatically selects the appropriate response mode based on context.

AI summary
A display control apparatus including an operation unit for receiving operation from a user, and a display unit, the display control apparatus includes a display control unit configured to display a predetermined code on the display unit, wherein, in a case where the predetermined code is displayed on the display unit, and the key with the first attribute is operated, a control unit performs the first processing, and in a case where the predetermined code is displayed on the display unit, and the key with the second attribute is operated, the control unit performs processing for hiding the predetermined code without performing the second processing.
