Self-Service POS Terminal Method Switching for User Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users unfamiliar with self-service POS terminal operations may experience stress due to lengthy registration processes, particularly when using methods like barcode recognition or object recognition, which can be confusing and time-consuming.
Innovation Solution
An information processing system that includes a self-service POS terminal and a store server, which acquires user information and switches between registration operation methods based on pre-defined time thresholds to reduce user stress, switching from object recognition to barcode recognition or vice versa when the registration time exceeds a predetermined average time for the user or their age group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If object recognition method is used for purchase registration, then registration speed is improved, but user stress increases due to confusion and complexity
Solution Approach 1:
The system changes the registration method based on user characteristics (age group) and registration time performance. For users in age groups 1-4, the system switches from object recognition to barcode recognition when registration time exceeds thresholds, thereby reducing user stress while maintaining productivity.
Solution Approach 2:
The system monitors registration time and provides feedback by switching registration methods based on whether the time exceeds predetermined thresholds. This feedback mechanism allows the system to adapt to user performance and reduce stress for users who take longer to complete registration.
2Ease of operation
If barcode recognition method is used for purchase registration, then ease of operation is improved, but registration time increases
Solution Approach 1:
The system dynamically changes the registration method based on user age group and registration time performance. For users in age groups 5-10 who complete registration within time thresholds, the system uses barcode recognition for ease of operation. For users exceeding time thresholds, the system switches to object recognition to reduce registration time.
3Ease of operation
If registration method is switched based on time thresholds, then user stress is reduced, but system complexity increases
Solution Approach 1:
The system implements dynamic switching between registration methods based on real-time monitoring of registration time and user age group. The system adapts its behavior during operation rather than using a fixed method, which increases user stress reduction while managing complexity through automated decision-making.
Solution Approach 2:
The system pre-establishes time thresholds and age group classifications before registration begins. This preliminary setup allows the system to automatically switch methods during operation without complex real-time decision-making, thereby reducing user stress while managing system complexity through pre-planned logic.

AI summary
An information processing device includes: a first acquirer, a second acquirer, and a switcher. The first acquirer acquires user information of a user who executes a registration operation on a purchased merchandise. The second acquirer acquires a first time value for the registration operation based on the user information. The switcher switches a registration operation method for the purchased merchandise when a second time value required for the registration operation exceeds the first time value.
