AR Identity Verification Using Document-Face Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems face challenges in providing a realistic and comfortable three-dimensional display experience due to mismatches between accommodation and vergence cues, leading to eye strain and discomfort, and also struggle with accurate identity verification tasks without human cognition.
Innovation Solution
The system employs a wearable augmented reality device with a stacked waveguide assembly and inward-facing and outward-facing imaging systems to simulate multiple depth planes, providing accurate depth cues and using facial recognition to verify identities by comparing facial features with document information.

1Shape
If traditional 3D display methods are used in augmented reality systems, then virtual content can be presented in three-dimensional view, but accommodation and vergence cues become mismatched leading to eye strain and discomfort
Solution Approach 1:
The patent introduces an intermediary optical system between the user's eyes and the display that manipulates light paths to provide separate accommodation and vergence cues. This intermediary mechanism allows the system to decouple the previously linked relationship between focusing distance and eye convergence, enabling realistic 3D presentation without the harmful side effects of traditional stereoscopic displays.
Solution Approach 2:
The patent segments the visual cue system into independent accommodation and vergence components. By providing different optical paths or focal points for each eye that can be independently controlled, the system separates the functions of depth perception (vergence) and focal accommodation, allowing each to be optimized independently and eliminating the mismatch that causes eye strain.
2Loss of information
If augmented reality systems present multiple visual elements simultaneously, then rich information can be displayed, but the human visual perception system becomes overwhelmed making comfortable and natural viewing difficult
Solution Approach 1:
The patent applies local quality by providing different optical characteristics to different regions or elements within the augmented reality display. Each virtual element can have tailored accommodation and vergence settings matched to its perceived depth and importance, allowing the system to present rich information while maintaining visual comfort through localized optimization of visual cues.

AI summary
An augmented reality device (ARD) can present virtual content which can provide enhanced experiences with the user's physical environment. For example, the ARD can detect a linkage between a person in the FOV of the ARD and a physical object (e.g., a document presented by the person) or detect linkages between the documents. The linkages may be used in identity verification or document verification.
