Solution Overview
Problem
Current decoding methods for two-dimensional codes do not effectively facilitate dynamic and recognizable interactions between electronic devices, particularly in scenarios where human-eye recognizable images are integrated with machine-readable codes, limiting user convenience and interaction capabilities.
Innovation Solution
A decoding method for dynamic recognizable two-dimensional codes involves sequentially displaying two-dimensional codes and human-eye recognizable images on a display unit with a defined pattern, including displaying duration and time intervals, and using a camera to capture and decode these images to determine verification codes for subsequent operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a static QR code with recognizable image is displayed, then user convenience is improved, but dynamic interaction capability is limited
Solution Approach 1:
The patent applies dynamics by transitioning from a static QR code to a dynamic display system where the QR code changes over time. The display unit shows different QR codes at different time intervals, enabling dynamic recognition. The camera captures images at specific moments, and the system determines which QR code corresponds to which time period, creating a dynamic interaction capability while maintaining ease of use.
Solution Approach 2:
The patent implements periodic action by displaying QR codes in a sequential manner with defined time intervals. The display unit presents QR codes periodically, and the camera captures images at corresponding time intervals. This periodic display and capture mechanism enables the system to differentiate between multiple QR codes while maintaining a simple user interface, thus improving both user convenience and dynamic interaction capability.
2Adaptability or versatility
If multiple QR codes are displayed simultaneously, then dynamic interaction is enabled, but decoding complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the display into multiple time segments. Each QR code is displayed during a specific time interval, and the camera captures images at corresponding time points. The system then segments the captured images based on time intervals and matches them with the corresponding QR codes. This temporal segmentation simplifies the decoding process by reducing multiple QR codes to sequential, time-differentiated displays, thus enabling dynamic interaction without excessive complexity.
Solution Approach 2:
The patent implements preliminary action by pre-defining the display sequence and time intervals of QR codes before the interaction begins. The display unit presents QR codes in a predetermined order with specified time intervals, and the camera is configured to capture images at these predetermined times. This preliminary arrangement of display and capture timing simplifies the decoding process, as the system already knows which QR code corresponds to which captured image, thus enabling dynamic interaction while managing decoding complexity.
3Measurement precision
If QR code display duration is extended, then recognition accuracy is improved, but time efficiency is reduced
Solution Approach 1:
The patent applies periodic action by displaying QR codes in rapid succession with defined time intervals. Each QR code is displayed for a specific duration, followed by a brief interval before the next QR code appears. The camera captures images at these time intervals, allowing the system to achieve recognition accuracy through multiple rapid captures rather than extended display duration. This periodic display and capture mechanism improves time efficiency while maintaining or enhancing recognition accuracy.
Solution Approach 2:
The patent implements continuity of useful action by maintaining continuous display and capture operations. The display unit continuously presents QR codes in sequence, and the camera continuously captures images at defined time intervals. This continuous operation ensures that the system always has current QR code information available for decoding, improving recognition accuracy without requiring extended display durations. The continuous nature of the operation optimizes time efficiency by eliminating idle periods between display and capture actions.
