Operation Unit Application Identification for Logout Rejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems, such as multifunction peripherals (MFPs), face challenges in allowing users to log out when there are unfinished jobs, as they prevent users from logging out due to running applications, leading to confusion about which application is causing the logout rejection.
Innovation Solution
The system acquires identification information for the first application executed on an operation unit, registers it, and controls the main unit to perform multiple functions. When a logout request is received while a second application is executing, it outputs rejection information and displays the name of the first application corresponding to the registered identification information on the operation unit's display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system prevents logout when an application is executing to ensure job completion, then job completion reliability is improved, but user interface clarity deteriorates because users cannot identify which application is preventing logout
Solution Approach 1:
The system provides feedback by displaying the name of the application that is preventing logout on the operation unit's display. This feedback mechanism resolves the contradiction by maintaining the logout prevention function (reliability) while adding visibility information that helps users understand which application is causing the restriction (interface clarity).
Solution Approach 2:
The operation unit acts as an intermediary between the main unit and the user. It receives the application name from the main unit and presents it to the user in a comprehensible format, bridging the gap between the system's internal state and the user's understanding.
2Reliability
If the system displays generic logout rejection messages to prevent unauthorized logout, then job completion is ensured, but user confusion increases due to lack of specific application information
Solution Approach 1:
The system enhances the feedback provided to users by including specific application name information in the logout rejection message. This resolves the contradiction by maintaining job completion assurance while preventing information loss about which application is causing the restriction.

AI summary
An information processing system includes a processor and a memory that stores a plurality of instructions which cause the processors to control executing a first application executed on an operation unit including a display, acquire identification information for identifying the first application in accordance with execution of the first application, register the identification information being acquired in the memory, control executing a second application executed on a main unit controlling the information processing system to perform multiple functions according to an instruction input to the operation unit, output, in response to receiving a request to log out while the second application is executing, rejection information indicating that the request to log out is rejected, and control, in response to outputting the rejection information, the display of the operation unit to display first name information indicating a name of the first application corresponding to the identification information registered in the memory.
