Service-End Forgotten-Item Reminders for Detectable and Undetectable Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems fail to notify users when items that cannot be detected by detection units are left behind, leading to unawareness of such items.
Innovation Solution
An information processing apparatus and system that includes a detection unit to identify items used or output in connection with a service, a setting unit to designate reminder targets, and a reminder unit to alert users about items that cannot be detected or have not been retrieved, using visual and auditory cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a detection unit is used to detect items, then items that can be detected are identified, but items that cannot be detected are not notified to users
Solution Approach 1:
The system segments items into two categories: detectable items (second-type items) and undetectable items (first-type items). The detection unit specifically detects second-type items, while the reminder unit handles notification for both categories, ensuring comprehensive coverage despite detection limitations.
Solution Approach 2:
The reminder unit acts as an intermediary between the detection unit and the user. It receives information from the detection unit about retrieved items and supplements this with information about undetected items, then provides comprehensive notifications to users about all items that should be collected.
2Reliability
If reminder notifications are provided for all items, then users are fully informed, but system complexity increases
Solution Approach 1:
The system divides items into first-type (undetectable) and second-type (detectable) categories. This segmentation allows the reminder unit to use different approaches for different item types: proactive reminders for first-type items and status-based reminders for second-type items, simplifying the overall logic while maintaining completeness.
Solution Approach 2:
The system performs preliminary classification of items into detectable and undetectable categories before the service execution. This preliminary action enables the reminder unit to prepare appropriate notification strategies in advance, reducing the complexity of real-time decision-making during service delivery.

AI summary
The information processing apparatus includes a display. The information processing apparatus accepts user operations via a GUI (graphical user interface) displayed on the display. When the service ends, the forgotten item notification screen is displayed on the display. In the forgotten item notification screen, a forgotten item reminder unit is provided for reminding a user who left behind a reminder target item, including the property of the user used in connection with the service. An individual reminder section is provided in a forgotten item reminder unit, to give an individual reminder to prevent the occurrence of leaving behind of each reminder target item, for a first-type item for which retrieval cannot be detected and a second-type item for which retrieval can be detected but which has not been retrieved, from among the reminder target items.
