Fixed-Mount Ticket Capture With Real-Time Image Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face delays and inefficiencies due to presentation errors when capturing graphic ticket codes, particularly with mobile devices, as users are unaware of the errors and cannot correct them promptly, leading to reduced throughput and potential schedule disruptions.
Innovation Solution
A permanently mounted ticket capture device with a camera-based system that displays captured image data in real time, allowing users to correct presentation errors immediately, and includes error detection and feedback mechanisms to enhance the reading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a camera-based capture device is used to capture graphic ticket codes, then the reading process can be automated, but presentation errors occur when users cannot see or correct the captured images, leading to delays
Solution Approach 1:
The patent implements a feedback mechanism by displaying the captured image on a display device visible to the user. This allows users to see what the camera has captured and immediately correct any presentation errors such as improper positioning, focus, or lighting, thereby eliminating delays caused by unsuccessful capture attempts.
Solution Approach 2:
The display device acts as an intermediary between the camera-based capture device and the user. It translates the captured image data into a visual format that the user can perceive and act upon, enabling the user to understand and correct presentation errors without directly interacting with the camera system.
2Device complexity
If users are not provided with visual feedback of captured images, then the system remains simple, but users cannot correct presentation errors promptly
Solution Approach 1:
By introducing a display device that shows captured images to users, the system provides immediate visual feedback. This enables users to understand what went wrong during capture and make corrections, significantly improving throughput without adding substantial complexity to the overall system architecture.
3Measurement precision
If the capture device requires precise positioning of the ticket code, then reading accuracy improves, but users struggle to achieve correct positioning without visual guidance
Solution Approach 1:
The display device provides real-time visual feedback showing whether the ticket code is properly positioned within the capture area. Users can see the captured image and adjust their positioning accordingly, making it easy to achieve the precise positioning required for accurate reading without complex instructions or training.
