Face Authentication Guidance for Visually Impaired Login
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing login technologies do not effectively assist users in the login process, particularly for users with visual impairments, as they lack intuitive guidance and accessibility features, leading to difficulties in performing successful login operations.
Innovation Solution
An information processing device and method that includes a face authentication system, a region image display, and guidance control section to assist users in moving their face or input device to a specified region on the screen, providing visual and audio cues for improved accessibility and ease of login.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If face authentication is performed automatically in the first stage without user awareness, then login speed is improved, but user accessibility for visually impaired users deteriorates because they cannot confirm what is happening
Solution Approach 1:
The system provides real-time visual feedback by displaying the user's face image on the screen during automatic face authentication, and provides audio feedback through guidance messages that explain each step of the login process. This allows visually impaired users to understand what is happening during authentication while maintaining automatic processing speed.
Solution Approach 2:
The system introduces an intermediary guidance control section that translates the automatic authentication process into user-friendly visual and audio instructions. This intermediary layer bridges the gap between automatic processing and user understanding, explaining each step without interfering with the automated flow.
2Ease of operation
If a region image specifying the movement target is displayed, then ease of operation is improved, but device complexity increases due to additional display components and control logic
Solution Approach 1:
The region image display functionality is merged with the existing imaged image display on the same screen. The guidance control section integrates the region image overlay with the face authentication interface, eliminating the need for separate display hardware while providing directional guidance to users.
3Ease of operation
If guidance control is provided to assist users in moving objects to the specified region, then user accessibility is improved, but loss of information increases due to additional audio and visual cues that may distract users
Solution Approach 1:
The system provides guidance information selectively based on user needs and situation. Audio guidance is provided for visually impaired users, while visual region images are displayed for all users. The guidance control section adjusts the amount and type of information provided to avoid overwhelming users while ensuring adequate assistance.

AI summary
An information processing device includes an imaged image display section configured to display an imaged image on a display, a registered user information retaining section configured to retain face identifying data of a registered user, a face authenticating section configured to detect a face image of the registered user present in the imaged image using the face identifying data retained in the registered user information retaining section, a region image display section configured to display, to the detected registered user, a region image specifying a region to which to move an object on the display, and a guidance control section configured to provide guiding assistance for facilitating the detected registered user moving the object to the region specified by the region image.
