Projected Face Authentication Alerts for Gate-Free Passage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-traffic passage management areas, face authentication systems face challenges in efficiently notifying individuals of their authentication results without the need for physical gates, leading to congestion and difficulty in recognizing individual results.
Innovation Solution
A notification apparatus and method that projects face authentication results onto the vicinity of individuals using a projector, allowing easy recognition of results without physical gates, and adjusts projections based on crowd density and individual positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gate is installed in the passage management area to control access, then access control reliability is improved, but the passage management area becomes crowded and processing speed decreases
Solution Approach 1:
The patent removes the physical gate from the passage management area and extracts only the essential function of access control. The system uses face authentication combined with projected notifications to achieve access control without the physical barrier, thereby maintaining reliability while eliminating congestion caused by gates.
Solution Approach 2:
The patent replaces the mechanical gate system with an optical notification system (projector) combined with face authentication. Instead of using a physical barrier to control access, the system projects authentication results directly onto the ground near individuals' feet, enabling contactless and efficient access control.
2Productivity
If face authentication processing is performed without a gate, then processing speed is improved, but the ability to notify individuals of authentication results deteriorates
Solution Approach 1:
The patent transitions the notification from traditional two-dimensional displays (screens, signs) to the ground plane, utilizing the third dimension (vertical projection onto horizontal surface). By projecting authentication results directly onto the ground near individuals' feet, the system ensures notifications are captured in the peripheral vision of passing individuals without requiring them to stop or look at traditional displays.
Solution Approach 2:
The patent introduces the projector as an intermediary between the face authentication system and individuals. The projector translates authentication results into visual notifications projected onto the ground, serving as a mediator that communicates results effectively to individuals passing through the area without requiring direct interaction with traditional notification devices.
3Loss of information
If traditional notification methods are used, then notification capability is improved, but recognition accuracy in crowded conditions deteriorates
Solution Approach 1:
The patent applies local quality by positioning notifications at the specific location where each individual needs to receive them - directly on the ground near their feet. This localized projection ensures that each person receives their authentication result at the appropriate moment and location, maintaining high recognition accuracy even in crowded conditions where traditional centralized notifications would be obscured.
Data Source
AI summary
This notification device has: a generation unit for generating image data of a face authentication result image that represents the face authentication result of a person passing through a passage control area and that is projected at the feet of the person passing through the passage control area, the face authentication result being obtained on the basis of image data from a camera imaging the passage control area; and a transmission unit for transmitting the generated image data to a projector.
