Interactive Display Spatial Code Generation for Voucher Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive displays lack the ability to provide unique spatial codes to different users and do not track how many times an optical pattern has been captured, allowing for potential misuse of electronic vouchers.
Innovation Solution
An interactive display system that generates unique spatial codes for each user, combines these codes with electronic offers to create new optical patterns, and presents them based on predefined renewal criteria, such as time or user proximity, while storing a list of generated codes to prevent duplicates and track usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the same optical pattern is used for multiple users, then the interactive display can present information efficiently, but the electronic voucher can be used multiple times and misused
Solution Approach 1:
The patent segments the optical pattern by incorporating a unique identifier specific to each user or transaction. This segmentation ensures that each optical pattern is distinct and can only be used by its intended recipient, preventing unauthorized multiple uses while maintaining efficient information delivery through standardized pattern formats.
Solution Approach 2:
The system implements feedback mechanisms by tracking and recording the usage status of each optical pattern. The display monitors whether a pattern has been previously used and can provide feedback signals to prevent redemption of duplicate patterns, thereby ensuring voucher integrity while maintaining operational efficiency.
2Ease of operation
If the interactive display presents the same optical pattern repeatedly, then it simplifies the display operation, but it loses tracking information about how many times the pattern has been captured
Solution Approach 1:
The patent applies preliminary action by pre-configuring the display system with tracking capabilities and unique pattern generation mechanisms before operation begins. This allows the system to automatically track capture frequency and usage statistics without requiring complex manual intervention, maintaining operational simplicity while preventing information loss.
Solution Approach 2:
The display system performs self-service by automatically generating unique optical patterns, tracking their usage, and maintaining records of capture frequency. This self-service capability eliminates the need for manual tracking while preserving operational simplicity, as the system autonomously manages information integrity.
3Reliability
If the interactive display generates and presents new optical patterns frequently, then it provides unique codes to different users, but it increases the complexity of code management and tracking
Solution Approach 1:
The patent implements universality by designing an integrated system where the display device performs multiple functions: generating unique codes, presenting optical patterns, tracking usage, and managing records all within a single unified platform. This multi-functionality reduces overall system complexity compared to separate systems for each function, while ensuring reliable unique code provision.

AI summary
An interactive display for presenting an optical pattern spatially encoding an electronic voucher is described. The interactive display comprises: a display arranged to present an optical pattern; and a controller coupled to the display. The controller is arranged to (i) generate a unique code; (ii) combine the generated unique code with an electronic offer to create a new optical pattern spatially encoding an electronic voucher; and (iii) present the new optical pattern on the display in response to a renewal criterion being satisfied.
