Graphic Code Display Triggered by Pre-Action and Scanner Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment methods require users to manually open an application and navigate to a payment code display entry before showing the code to a scanning device, which is cumbersome and inefficient.
Innovation Solution
A method and terminal that automatically display a graphic code upon detecting a pre-action, such as a screen orientation change, using sensor data to identify the action and image capture to detect a code scanning device, eliminating the need for manual application navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually open applications and navigate to display payment codes, then the payment code can be displayed, but the operation process becomes cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary actions by capturing images and detecting code scanning devices before the user needs to display the payment code. The terminal continuously monitors for code scanning devices and pre-positions the payment code display, eliminating the need for users to manually navigate through applications and saving time by having everything ready before the user initiates the payment action.
Solution Approach 2:
The terminal performs self-service by automatically detecting when a code scanning device is present and autonomously displaying the payment code without requiring user intervention to open applications or navigate interfaces. The system serves itself by monitoring sensor data, capturing images, detecting scanning devices, and triggering code display automatically based on the detected actions.
2Productivity
If the terminal automatically detects and displays payment codes, then the payment process efficiency improves, but the device complexity increases
Solution Approach 1:
The terminal achieves multi-functionality by using its existing camera and sensor systems for multiple purposes: the camera captures images not only for normal use but also for detecting code scanning devices, and the sensor system serves both general sensing functions and for detecting user actions related to payment. This approach increases productivity through automatic code display while minimizing the need to add separate dedicated hardware for the detection function.

AI summary
A graphic code display method, a device, a terminal, and a storage medium are provided, belonging to the mobile payment field. An example method comprises: identifying an action, in an unlocked state, based on sensor data collected by a sensor; capturing an image by camera, in response to an identified pre-action, the pre-action being the action prior to displaying the graphic code to a code scanning device; detecting the code scanning device in the captured image to acquire detection result; and displaying the graphic code, in response to the detection result indicating that the image contains the code scanning device. A user only needs to show the pre-action for displaying a graphic code, and mobile terminal may automatically trigger to display the graphic code, without pre-opening an application and a graphic code display function, simplifying the graphic code display process.
