Solution Overview
Problem
Conventional programmable display apparatuses cannot permit access to applications using facial authentication and fail to display screens corresponding to authenticated users, leading to inconsistent user experiences and unauthorized access.
Innovation Solution
A programmable display apparatus with a display control unit, storage unit for user feature data, and authentication unit that performs facial authentication to permit access to applications and display screens tailored to authenticated users based on their identification information and operation authorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial authentication is implemented in programmable display apparatus, then security and user identification are improved, but device complexity increases
Solution Approach 1:
The patent combines the facial authentication functionality with the existing HMI processing unit and display control unit, merging multiple functions (facial recognition, authentication, and display control) into integrated processing components. This reduces overall system complexity while maintaining security improvements.
Solution Approach 2:
The display control unit is designed to perform multiple functions: it controls the display device, processes facial authentication results, determines user operation authorities, and selects appropriate operation screens. This multi-functionality eliminates the need for separate dedicated components, improving security while managing device complexity.
2Adaptability or versatility
If screens are customized based on user identity and authority, then user experience and adaptability are improved, but device complexity increases
Solution Approach 1:
The system dynamically selects and displays different operation screens based on real-time authentication results and user operation authorities. The display control unit adapts the interface presentation according to the authenticated user's identity and permissions, providing customized user experiences without requiring separate physical devices for different user types.
Solution Approach 2:
The system changes display parameters (screen selection, interface configuration) based on user authentication results and operation authorities. By modifying software-level display parameters rather than hardware configuration, the system achieves high adaptability while minimizing device complexity.
3Measurement precision
If facial authentication processing is added, then measurement precision of user identity is improved, but processing time increases
Solution Approach 1:
The system performs facial image capture and initial processing in advance before final authentication determination. The HMI processing unit prepares facial images and passes them to the display control unit, which has already begun processing, enabling parallel operations that reduce overall authentication time while maintaining high identification accuracy.
4Ease of operation
If integrated authentication and display control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the authentication processing and display control functions into the same processing unit (display control unit). This integration allows automatic transition from facial capture to authentication to screen selection without requiring separate operational steps or interfaces, greatly simplifying user operation while managing complexity through functional consolidation.
Data Source
AI summary
Provided is a programmable display apparatus that can permit access to an application through facial authentication, and can display a screen corresponding to an authenticated user after the access is permitted. The programmable display apparatus stores feature data of faces of a plurality of users and screen data for displaying a plurality of screens. The programmable display apparatus performs facial authentication based on image data of a user obtained through image capture and on the feature data. The programmable display apparatus permits a user to access the application if the user has been authenticated. Upon permitting the access, the programmable display apparatus displays, on a display, a screen corresponding to the authenticated user from among the plurality of screens.
