Problem
Challenges exist in producing augmented reality technologies that facilitate a comfortable, natural-feeling, rich presentation of virtual image elements amidst real-world imagery, due to the complexity of the human visual perception system.
Innovation Solution
A head-mountable augmented reality display system that outputs light with variable wavefront divergence, equipped with inwardly and outwardly-directed sensors, processors, and computer storage media, performs neurological analysis, and provides perception aids based on environmental triggers and user reactions to stimuli.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality display presents virtual image elements among real-world imagery, then the richness and natural feeling of the presentation is improved, but the complexity of the system increases due to the complexity of the human visual perception system
Solution Approach 1:
The system performs neurological analysis and determines user reactions to stimuli before presenting augmented reality content. Environmental triggers are identified in advance, and perception aids are prepared based on pre-determined neurological conditions, allowing the system to adapt content presentation without real-time complex processing
Solution Approach 2:
The patent introduces sensors as intermediary components that detect environmental triggers and user reactions. These sensors act as mediators between the real world and the augmented reality system, capturing physiological and environmental data that inform content presentation decisions, thereby simplifying the overall system architecture
2Measurement precision
If the display system performs neurological analysis and provides perception aids, then the ability to detect and modify neurological conditions is improved, but the device complexity increases
Solution Approach 1:
The augmented reality display system performs multiple functions including presenting virtual content, performing neurological analysis, detecting environmental triggers, and providing perception aids. By consolidating these diverse functions into a single multi-functional platform, the system reduces overall complexity compared to having separate dedicated systems for each function
Solution Approach 2:
The system uses sensors integrated into the display device itself to perform neurological analysis and detect environmental triggers, rather than requiring external separate testing equipment. The display system serves its own diagnostic and adaptive functions, eliminating the need for additional external devices

AI summary
In some embodiments, a display system comprising a head-mountable, augmented reality display is configured to perform a neurological analysis and to provide a perception aid based on an environmental trigger associated with the neurological condition. Performing the neurological analysis may include determining a reaction to a stimulus by receiving data from the one or more inwardly-directed sensors; and identifying a neurological condition associated with the reaction. In some embodiments, the perception aid may include a reminder, an alert, or virtual content that changes a property, e.g. a color, of a real object. The augmented reality display may be configured to display virtual content by outputting light with variable wavefront divergence, and to provide an accommodation-vergence mismatch of less than 0.5 diopters, including less than 0.25 diopters.
