Electronic Device Control via Contactless User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require complex operations for users to execute their favorite processes, as they lack a simplified method for user authentication and job selection based on registered identification information.
Innovation Solution
An electronic device that authenticates users via a contactless medium, utilizing a control unit to refer to a storage unit for registered job settings, displaying a home screen when no job is registered, executing a single registered job automatically, and allowing users to select from multiple registered jobs through an operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user authentication is implemented with multiple registered jobs, then users can select from multiple processes, but the number of operations increases
Solution Approach 1:
The system pre-registers multiple jobs associated with each user's identification information in the storage unit. When authentication succeeds, the control unit automatically retrieves and presents these pre-registered jobs to the user, eliminating the need for users to manually configure or search for available processes.
Solution Approach 2:
The control unit automatically manages the job selection process by querying the storage unit for registered jobs based on the authenticated user's ID. The system serves the appropriate job list to the user without requiring manual intervention or complex configuration steps.
2Ease of operation
If automatic job execution is implemented when only one job is registered, then operation is simplified, but flexibility is reduced
Solution Approach 1:
The system dynamically adjusts its behavior based on the number of registered jobs. When only one job is found for the authenticated user, the system automatically executes it without prompting. When multiple jobs are registered, the system switches to presenting a selection list, allowing the user to choose. This dynamic adaptation optimizes both ease of operation and flexibility.
Solution Approach 2:
The system changes its operational parameter (automatic execution vs. selection presentation) based on the count of registered jobs. The control unit queries the storage unit, counts the available jobs, and adjusts the interaction mode accordingly, transforming the system's behavior to match the situation.
3Loss of information
If home screen is displayed when no job is registered, then user is informed of available options, but additional operation steps are required
Solution Approach 1:
The control unit provides feedback to the user by displaying the home screen when no jobs are registered for the authenticated user. This feedback mechanism informs the user that no processes are currently available, guiding them to either register new jobs or use a different authentication method.

AI summary
Provided is an electronic device in which, after user authentication is executed on the basis of identification information of a user acquired through a reader configured to read information from a contactless medium, a control unit causes a display unit to display a home screen when no job corresponding the identification information is registered, the control unit executes a process according to one piece of a job when only the one job is registered, and the control unit executes a process according to a job selected through an operation of the user from among two or more jobs when the two or more jobs are registered.
