Iris Detection Alignment via UV Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle entry and activation systems rely on mechanical keys, key fobs, and phone-as-a-keys, which can be inconvenient and lack advanced biometric security, particularly in scenarios where users want to personalize settings without physical keys.
Innovation Solution
An iris-detection system is implemented in vehicles, using a camera, puddle lamp, and UV source to guide users into aligning their irises for recognition, allowing for secure and convenient vehicle entry and feature activation, including personalized settings, without the need for physical keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If iris-detection system with guidance indicators is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by projecting guidance indicators (arrows, footprints) before the actual iris detection occurs. These indicators pre-guide the user to the correct position and orientation, making the alignment process intuitive and easy without requiring complex real-time feedback mechanisms during detection
Solution Approach 2:
The puddle lamp and UV source act as intermediary elements between the camera system and the user. Instead of directly displaying information on the camera or requiring complex user-camera interaction, the system uses projected indicators on the ground and window as mediators to guide user positioning, simplifying the overall interaction
2Ease of operation
If multiple guidance indicators are projected, then ease of operation is improved, but use of energy increases
Solution Approach 1:
The projection system operates periodically rather than continuously - activating puddle lamp and UV source only when a user approaches (detected via motion sensors or proximity detection) and deactivating when no user is present. This reduces overall energy consumption while maintaining effective guidance when needed
Solution Approach 2:
The system projects only the necessary guidance elements (arrows pointing to camera, footprints indicating standing position) rather than comprehensive directional information. This partial action provides sufficient guidance for iris alignment without the energy cost of multiple projection systems or continuous multi-directional indicators

Data Source
AI summary
Method and apparatus are disclosed for iris-detection alignment for vehicle entry and feature activation. An example vehicle includes a window, a camera facing the window, a puddle lamp to project an indicator pointing toward the camera, a UV source, and a controller. The controller is to project, via the UV source, a display onto the window upon detecting a user aligns with the indicator. The controller also is to provide directions to the user, via the display, to position an iris in front of the camera and activate a vehicle feature upon identifying the user via iris recognition.
