AR Glasses Location Rules for Low-Vision Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality glasses do not effectively present location-based rules to low-vision users, as they lack the ability to determine the user's physical location and field of view, and adapt the display accordingly.
Innovation Solution
Incorporating a positioning device to determine the user's physical location and field of view, and a receiver to input the user's level of vision, with a display that magnifies images based on this information to enhance visibility for low-vision users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If augmented reality glasses display location-based rules to low-vision users, then the usability and accessibility for low-vision users is improved, but the device complexity increases due to the need for positioning devices, receivers, and adaptive display systems
Solution Approach 1:
The augmented reality glasses are designed to serve multiple functions: they act as a positioning device to determine physical location, a receiver to obtain field of view information, and a display device to present location-based rules. By integrating these multiple functions into a single wearable device, the system improves accessibility for low-vision users without requiring separate devices for each function.
Solution Approach 2:
The system uses an intermediary processing layer that receives raw data from positioning devices and receivers, processes this information to determine physical location and field of view, and then adapts the display accordingly. This intermediary layer manages the complexity by organizing and coordinating the various components rather than requiring direct integration between all elements.
2Illumination intensity
If the display magnifies images based on user's vision level, then the visibility for low-vision users is improved, but the adaptability requirements increase the system complexity
Solution Approach 1:
The display system dynamically adjusts its magnification level based on the user's vision requirements. Rather than providing fixed magnification, the system continuously adapts the display parameters according to the user's needs, allowing the visibility to be optimized in real-time while managing adaptability through automated adjustment algorithms.
Solution Approach 2:
The system changes display parameters such as magnification level, contrast, and brightness based on the user's vision level input. By automatically adjusting these parameters according to the determined vision requirements, the system improves visibility without requiring manual intervention, thus managing the complexity of adaptability through automated parameter optimization.
3Loss of information
If the system determines physical location and field of view to present relevant rules, then the information relevance is improved, but the measurement and detection complexity increases
Solution Approach 1:
The system merges the positioning device and field of view detection into a unified location determination system. By combining these measurement functions and integrating them with the display system, the patent reduces the overall measurement complexity while maintaining high information relevance. The merged system processes location and orientation data together to present contextually relevant location-based rules.
