Ultra-Dynamic QR Code Client-Side Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional QR codes are static, limiting their ability to adapt to changes in destination URLs or include client-side events, requiring server-side redirection and updates, which is inefficient and prone to obsolescence.
Innovation Solution
The development of an Ultra-Dynamic QR Code (UDQRC) that changes its visible pattern in response to local user inputs or environmental changes, encoding dynamic data such as real-time status or interaction information directly on the client side, rather than relying on server-side redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional static QR codes are used, then the implementation is simple and reliable, but the adaptability to changes in destination URLs or client-side events is poor
Solution Approach 1:
The patent implements dynamic QR codes that can change their encoded information in real-time based on client-side events, user interactions, or environmental changes. The QR code transitions from a static image to a dynamic representation that updates its destination URL or encoded data without requiring server-side redirection, thereby improving adaptability while maintaining manageable complexity through client-side processing.
Solution Approach 2:
The invention changes the parameters of the QR code by allowing the encoded destination URL or data to be modified dynamically. Instead of using a fixed destination, the system updates the QR code's encoded information based on changing conditions such as user actions, environmental sensors, or application state, enabling the same QR code to point to different destinations at different times.
2Productivity
If server-side redirection is used to update QR code destinations, then the QR code can adapt to changes, but the reliance on server-side processing increases and efficiency decreases
Solution Approach 1:
The patent enables the QR code system to update its own destination information through client-side processing. The display device or mobile application locally generates and updates the QR code based on client-side events without requiring external server intervention for each update. This self-service capability improves productivity by eliminating server round-trips for QR code updates while reducing dependency on server-side infrastructure.
3Loss of information
If static QR codes are used, then the system is reliable and simple, but the ability to include client-side events and real-time status information is limited
Solution Approach 1:
The patent adds a temporal dimension to QR codes by enabling them to represent different information at different times. The QR code evolves from a single-state identifier to a multi-state representation that can encode varying information based on time, user interaction, or environmental conditions. This dimensional addition allows the inclusion of real-time status and client-side events without significantly increasing system complexity.
Data Source
AI summary
Methods for creating a bidirectional user interface associated with an audiovisual broadcast are disclosed. Along with the audiovisual broadcast, instructions are provided to generate a first user interface overlaid over the audiovisual broadcast by a device displaying the audiovisual broadcast. Upon capturing an identifier in the UI with a second device, a second user interface on the second device is generated, and the first user interface is updated to display information in conjunction with the second user interface. Methods are also disclosed for an Ultra-Dynamic Quick Response (QR) code. After a QR code encodes data that represents one or more variable values associated with an interface, and in response to receiving an input event representing that a change in value has occurred of at least one variable value, the interface is updated to replace the first QR code with a second QR code encoding data representing the change.
