Mobile Terminal Code Display Adaptation for Scanner Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in performing payment tasks with mobile terminals, as they need to manually find and show codes to clerks and often exchange codes multiple times for recognition.
Innovation Solution
A mobile terminal equipped with a sensing unit to detect code scanning situations and a controller to automatically display codes, adjust their direction according to the light output from the scanner, and perform payment tasks sequentially or in bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually finds and shows codes to the clerk for payment tasks, then the payment can be performed, but the user has to go through complicated processes and exchange codes multiple times
Solution Approach 1:
The mobile terminal automatically performs the code display function by itself when detecting a code scanner through the sensing unit. The controller monitors for the presence of a code scanner and autonomously displays the appropriate code on the display unit without requiring user intervention to manually find and show the code to the clerk.
Solution Approach 2:
The mobile terminal prepares the code for display in advance by pre-loading payment information and codes. When the sensing unit detects a code scanner, the controller immediately displays the pre-prepared code, eliminating the time delay of manual code retrieval and exchange during the payment process.
2Productivity
If the user performs multiple payment tasks by exchanging codes sequentially, then all tasks can be completed, but the process becomes time-consuming and inefficient
Solution Approach 1:
The mobile terminal combines multiple payment tasks into a single automated process. The sensing unit detects the code scanner once, and the controller automatically manages the display of codes for multiple payment tasks in sequence or simultaneously, merging what would otherwise require multiple separate manual code exchanges into one efficient operation.
Solution Approach 2:
The mobile terminal maintains continuous useful action by automatically managing the entire payment task sequence without interruption. Once the code scanner is detected, the controller continuously manages code display for multiple tasks without requiring the user to manually intervene between tasks, ensuring uninterrupted and efficient payment processing.
3Reliability
If the code is displayed in a fixed direction, then the display is simple, but it may not be properly scanned when the terminal orientation varies
Solution Approach 1:
The code display transitions from a static fixed-direction display to a dynamic adaptive display. The controller adjusts the code orientation and direction based on real-time detection of the code scanner's position and the terminal's orientation, ensuring the code is always displayed in the optimal direction for scanning regardless of how the user holds the device.
Solution Approach 2:
The system implements feedback by monitoring the code scanner's position and the terminal's orientation through the sensing unit, then using this information to adjust the code display direction accordingly. This closed-loop control ensures the code is always displayed in the correct orientation for reliable scanning, with the display automatically adapting based on detected conditions.
