Payment System Object Exclusion via Touch Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems in canteen facilities struggle to efficiently exclude incorrectly recognized objects from payment targets, leading to complex operations when personal belongings are mistaken for products.
Innovation Solution
A payment system that includes an acquisition unit to capture images, an estimation unit to identify objects, a display unit to show product information, a reception unit to receive user input, and a registration unit to register or exclude objects as payment targets based on user input, allowing users to easily register or exclude incorrectly recognized items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system automatically recognizes products from captured images, then payment processing speed is improved, but incorrect recognition of personal belongings as products occurs
Solution Approach 1:
The system displays recognized objects and their estimated product information on a screen, allowing users to verify recognition results. When an object is incorrectly recognized (e.g., personal belongings mistaken for products), users can provide feedback by touching the display to exclude it from payment targets, thereby correcting recognition errors while maintaining automated processing speed
Solution Approach 2:
The system enables users to independently correct recognition errors by simply touching the display screen to exclude incorrectly recognized objects. This self-service mechanism allows users to quickly resolve misrecognitions without requiring staff intervention, maintaining high processing speed while improving recognition reliability
2Reliability
If the system requires manual correction of incorrectly recognized objects, then recognition accuracy is improved, but operation complexity increases
Solution Approach 1:
The system extracts the correction function from complex manual operations and simplifies it to a single touch action on the display screen. Users can exclude incorrectly recognized objects by simply touching their representation on the screen, removing the need for complicated cancellation procedures while maintaining high recognition accuracy
3Reliability
If the system displays detailed product information for confirmation, then payment accuracy is improved, but processing time increases
Solution Approach 1:
The system displays essential product information (image and estimated product name) rather than exhaustive details, providing just enough information for users to quickly verify recognition accuracy. This partial information display approach maintains payment accuracy while minimizing confirmation time

AI summary
A payment system includes: an acquisition unit that acquires an image including a payment target product; an estimation unit that estimates a product that corresponds to an object identified from the image; a display unit that displays information on the product in association with the object; a reception unit that receives input indicating intention to register the object, which indicates whether to register the object as the payment target product, from a user; and a registration unit that registers the object in accordance with the input. The registration unit registers the object as the payment target product upon receiving an input indicating that the object should be registered, and does not register the object as the payment target product upon receiving an input indicating that the object should be excluded from the payment target products.
