Automatic Input Device Assignment for Multi-User Login Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-user game apparatuses and information processing systems, existing methods for assigning input devices to users can be cumbersome, requiring users to declare device usage each time, leading to inefficiencies and user inconvenience.
Innovation Solution
The system employs a combination of user authentication methods, including automatic login, face authorization, and user selection screens, with the assignment processing unit automatically assigning connected input devices to users based on their login status and device type, eliminating the need for users to manually select devices each time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the game apparatus inquires the user about device usage every time an inputting device is connected, then the device can be assigned to the correct user with certainty, but the user experiences cumbersome linkage work and reduced convenience
Solution Approach 1:
The system automatically detects when an inputting device is connected and autonomously performs the assignment process by displaying a user selection screen and processing the selection, eliminating the need for manual intervention while ensuring accurate device-user linkage
Solution Approach 2:
The system prepares a user selection screen in advance that presents all logged-in users as options, allowing the user to quickly select the intended user without going through a cumbersome inquiry process each time a device is connected
2Ease of operation
If the system automatically assigns inputting devices to logged-in users without inquiry, then user convenience is improved, but the accuracy of device assignment may be compromised when multiple users are logged in
Solution Approach 1:
The user selection screen acts as an intermediary between automatic detection and final assignment, presenting all logged-in users as options and allowing the user to make the final selection, thus combining automatic convenience with assignment accuracy
3Reliability
If the system processes device assignment manually through user declaration, then assignment accuracy is ensured, but the processing time and user effort increase
Solution Approach 1:
The system prepares the user selection screen with all logged-in users displayed as options in advance, allowing the user to quickly select the intended user without going through a time-consuming manual inquiry process
Solution Approach 2:
The system automatically detects device connection, displays the selection screen, and processes the assignment when the user selects, eliminating the need for manual intervention while ensuring accurate assignment

AI summary
A login processing unit 132 performs a login process of a user. An assignment processing unit 130 assigns an inputting device connected to an information processing apparatus 10 to a user. An assignment processing unit 136 controls an assignment process of the inputting device in response to the number of users who are in a login state and executes an assignment process which is different between a case in which the number of users in a login state is one and another case in which the number of users in a login state is two or more. The assignment processing unit 136 assigns, when the number of users in a login state is one, the inputting device connected to the information processing apparatus 10 to the one user.
