Acquiring/Recognising Eyes TRIZ Cases
- Iris Authentication UI Pupil Diameter Control
Dynamic display luminance adjustment controls pupil diameter, ensuring accurate iris authentication in varying outdoor illumination conditions.
- Iris Recognition Guidance Device with Mirrored Visual Feedback
Mirrored visual feedback guides users to align the optical axis, resolving the contradiction between security performance and ease of operation.
- Iris Recognition Camera Module Using Holographic Optical Element
A lens module integrates a holographic optical element with refractive lenses to form an iris recognition camera system.
- 3D Gaze Tracker Using Time-of-Flight Camera for Head-Free Tracking
A 3D gaze tracker combines time-of-flight and picture cameras to determine gaze vectors without head stabilization.
- Eye Tracking Illuminator Using P-Polarized Light at Brewster's Angle
P-polarized light incident at Brewster's angle reduces unwanted reflections from glasses, enabling accurate pupil identification.
- Head-Mounted Device Optical Assembly Positioning
A head-mounted device adjusts optical assemblies using a user-specific model derived from facial geometry scans.
- Single Sensor Biometric Capture with Dynamic Illumination
A single sensor captures facial and iris images by adjusting illumination and exposure settings between acquisitions.
