Acquiring/Recognising Eyes TRIZ Cases
- Annular Spring Glenosphere for Impact Absorption
An annular spring member couples a glenosphere to a tray, absorbing off-axis impact energy that rigid implants cannot handle.
- Liveness Detection via Multi-Modal Challenge Responses
Multi-modal challenge responses distinguish live users from spoof attacks, enhancing authentication reliability.
- Iris Recognition Device Noise Removal via Phase Synchronization
Phase-based sampling removes ghost artifacts caused by ambient light, improving biometric accuracy in mobile devices.
- Interactive 3D Plot Overlay for Augmented Reality Displays
Mobile device overlays interactive three-dimensional plots on camera views to visualize real-time mathematical relationships.
- Bovine Iris Recognition Using SIFT Feature Bags
A SIFT feature bag method extracts invariant points from bovine iris images for reliable identification.
- Pupil Extraction Using Thresholding and Circle Fitting
A pupil extractor applies thresholding to eye region data and uses circle fitting to identify the boundary.
- Astigmatic Lens Distance Measurement
An astigmatic lens generates multiple focal lengths to measure object distance via reflected light shape changes, avoiding complex circuit configurations.
- Head Imaging Biometric Authentication with Gesture Recognition
Processor analyzes head imaging and limb gestures to resolve the contradiction between authentication reliability and user convenience.
- Smartphone Pupillary Light Reflex Detection for Impairment Assessment
Portable video capture device measures pupillary light reflex changes to estimate cognitive impairment levels.
- Focus Tunable Lens for AR Vergence Accommodation Conflict
Dynamic focal length adjustment aligns vergence distance with virtual image depth, resolving the vergence accommodation conflict that causes eye strain.
- Multi-Perspective Eye Acquisition via Mirror Reflection
Segmented mirrors capture multi-angle eye reflections to resolve occlusion issues while maintaining low production costs.
