Solution Overview
Problem
Existing gambling terminals lack user control over transactions, particularly in the handling and verification of gambling receipts, leading to potential substitution issues and unreliable information detection due to incorrect positioning and sensitivity to ambient light.
Innovation Solution
A gambling terminal design with a dual-sided mount allowing simultaneous user and agent access, equipped with a digital camera, lighting for pattern projection, and image correction, along with user interface touch screens for validation and correction of information, ensuring transparency and reliability in document acquisition and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a digital camera is used to acquire images of gambling documents, then the speed of image acquisition is improved, but the reliability of information detection deteriorates due to incorrect positioning
Solution Approach 1:
A positioning mark is introduced as an intermediary element between the gambling document and the camera. The mark serves as a reference that enables the system to automatically detect and correct the position and orientation of the document, thereby maintaining high acquisition speed while improving detection reliability.
Solution Approach 2:
The manual positioning mechanism is replaced with an automated optical recognition system. Instead of requiring physical alignment by the agent, the system uses image processing to detect the positioning mark and automatically calculates correction parameters, substituting mechanical precision with computational accuracy.
2Ease of operation
If ambient light is present in the environment, then the ease of operation is improved, but the reliability of image acquisition deteriorates due to parasitic light interference
Solution Approach 1:
The positioning mark uses specific color properties that allow it to be distinguished from the surrounding environment and gambling documents. By utilizing color contrast and spectral characteristics, the system can reliably detect the mark even in the presence of ambient light, filtering out parasitic light interference through color-based image processing.
3Ease of operation
If the gambling document is not flat, then the ease of operation is improved, but the quality of image acquisition deteriorates due to document curvature
Solution Approach 1:
The system implements a feedback mechanism where the acquired image is analyzed to detect the position and orientation of the positioning mark. Based on this feedback, the system automatically calculates geometric transformation parameters to correct for document curvature and non-flat positioning, restoring image quality without requiring perfect document placement.
4Device complexity
If the agent handles the gambling document alone, then the device complexity is reduced, but the transparency of the transaction deteriorates
Solution Approach 1:
The system adds a visual dimension to the transaction process by projecting the captured image onto a display visible to the user. This allows the user to verify what the system sees without complicating the physical handling process, maintaining simplicity while enhancing transparency through spatial separation of the verification function.
