Barcode Visual Pairing for Mobile Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for data transfer between mobile devices require significant user interaction, including discovery, pairing, and data exchange steps, which can be cumbersome and time-consuming, especially in situations where quick data exchange is necessary, such as during driving.
Innovation Solution
A visual data transfer method using cameras to initiate and perform data exchange between devices by displaying visual tags on one device's screen, which are then captured and processed by the other device to facilitate data transfer, reducing the need for traditional pairing and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data transfer methods (discovery, pairing, authentication) are used, then data exchange can be performed, but user interaction time and complexity increase significantly
Solution Approach 1:
The system performs discovery and pairing actions in advance by having devices continuously broadcast and listen for pairing requests. When a user points the camera at another device, the discovery and pairing are already prepared, allowing immediate data transfer without real-time user interaction for each step.
Solution Approach 2:
The system enables automatic authentication where the receiving device self- verifies the transmitted data and automatically establishes the connection. The camera capture triggers automatic pairing and authentication processes without requiring manual password entry or confirmation from the user.
2Reliability
If traditional pairing and authentication processes are used, then security is maintained, but the number of操作步骤 and complexity increase
Solution Approach 1:
The patent combines discovery, pairing, and authentication into a single integrated action triggered by camera capture. Instead of separate steps for each function, the system merges them into one unified process where a single camera capture initiates all necessary procedures simultaneously.
Solution Approach 2:
The system replaces manual mechanical interactions (typing passwords, pressing buttons, navigating menus) with optical capture. The camera-based input substitutes for traditional mechanical user interface interactions, reducing the number of physical操作步骤 while maintaining security through automatic verification.
3Measurement precision
If manual data entry and pairing is required, then data accuracy can be verified, but productivity and speed of data transfer decrease
Solution Approach 1:
The system replaces manual data entry with optical capture using the camera. Data is transferred visually through the camera feed, eliminating the need for manual typing and verification while maintaining accuracy through automated image recognition and data extraction from the visual stream.
Solution Approach 2:
The system creates a visual copy of the data transmission process through the camera feed. Instead of manual entry, the receiving device captures a visual representation of the transmitted data and automatically processes it, enabling fast replication of data without manual verification steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for quick and convenient data transfer between devices with minimal user interaction, enabling fast and intuitive data exchange without the need for complex setup or manual input, particularly beneficial in time-critical scenarios.
Implementation Method 1
A camera may be used to initiate and perform the data exchange. Both devices need only be held against each other (e.g., so that the devices are touching each other) in order to initiate the transfer.
Data Source
AI summary
A method of operating first and second electronic devices includes providing the first device with a display screen, and providing the second device with a camera. A tag is displayed on the screen. The tag is associated with information stored within the first device. An image of the tag is captured by use of the camera. The captured image is processed within the second device to thereby recognize the tag. In response to the recognition of the tag, the second device is used to initiate a transfer of the information to the second device.
