Face Authentication Interface Segmentation for Restricted Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing face authentication systems complicate operations for accessing information corresponding to the authentication state, particularly in restricted admission areas, as they do not provide a convenient user interface for users such as children and senior citizens.
Innovation Solution
An authentication system with a touch panel and camera that generates an input acceptance screen with a message area for tap operations, transitioning to a menu screen with menu items for accessing information based on the authentication state, including features like thermal sensors for body temperature detection and motion sensors for presence detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional face authentication interface is used, then the authentication function is achieved, but the operations for accessing information become complicated
Solution Approach 1:
The interface is segmented into distinct functional areas: a first area for message display and a second area for face authentication. This segmentation allows users to access different information by tapping different areas, simplifying the interaction model while maintaining comprehensive functionality.
Solution Approach 2:
The first area serves multiple functions: it displays messages to users and acts as a selectable region for accessing menu screens. This multi-functionality reduces the number of separate controls needed, thereby simplifying the overall interface structure.
2Loss of information
If a detailed authentication interface is provided, then information access is comprehensive, but the operation becomes complicated
Solution Approach 1:
The interface transitions from a two-dimensional display to a three-dimensional interaction model by incorporating touch input. Users can access different information layers by tapping different areas of the screen, creating a depth dimension in the user interface that organizes information access hierarchically.
Solution Approach 2:
The touch panel acts as an intermediary between the user and the authentication system. By tapping the first or second area, users can access menu screens that provide comprehensive information without requiring complex direct interactions with the authentication process itself.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient access to information related to the authentication state through simple tap operations, improving usability for all users, including those in restricted admission areas.
Implementation Method 1
a thermal sensor configured to detect a body surface temperature of the target person
Implementation Method 2
a camera configured to acquire an image used for the face authentication by capturing the target person
Implementation Method 3
a motion sensor configured to detect presence or absence of the target person

AI summary
In an authentication device, an input acceptance screen generation means generates an input acceptance screen which includes a first area for displaying a message and receives a tap operation by a target person for a face authentication in the first area or in a second area which is provided separately from the first area. A menu screen generation means generates a menu screen including one or more menu items as a screen after transitioning from the input acceptance screen in response to the tap operation performed to the first area or the second area.
