Solution Overview
Problem
Current smart glasses lack accurate object identification within a viewing area, leading to inefficient content display, significant computational power usage, privacy concerns, and inability to seamlessly switch between objects, resulting in distracting and annoying user experiences.
Innovation Solution
A smart glasses viewing area management system that defines a viewing cone area using ultra-wideband RF tags and antennas, enabling real-time field of view analysis to turn content on or off based on user focus, allowing seamless transitions between objects by calculating distances and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera, GPS, and gyroscope are used to determine content display, then object location can be identified, but computational power consumption increases significantly
Solution Approach 1:
The patent extracts and removes the camera component from the smart glasses system, replacing it with audio-based object identification. This eliminates the need for complex image processing while maintaining the ability to identify and track objects, thereby significantly reducing computational power consumption and energy usage.
Solution Approach 2:
The patent substitutes the mechanical/optical system (camera) with an acoustic system (microphones and audio processing). This replacement uses sound waves instead of light capture and complex image analysis, reducing the computational burden while achieving similar object identification functionality.
2Measurement precision
If camera is used to identify and target objects, then object location can be determined, but privacy issues arise and camera use is banned in many public venues
Solution Approach 1:
The patent removes the camera component entirely from the system, eliminating the privacy invasion associated with visual recording and image capture. The audio-based approach does not capture visual information, thereby respecting user privacy and complying with venue restrictions on camera usage.
Solution Approach 2:
The patent introduces audio signals as an intermediary medium for object identification, replacing direct visual capture. This intermediary approach allows the system to identify objects and their locations without directly observing or recording visual information, thereby maintaining privacy while achieving the same functional goal.
3Productivity
If content is displayed without viewing area management, then content can be shown continuously, but user experience becomes distracting and annoying
Solution Approach 1:
The patent implements dynamic content display management where the system continuously monitors the user's field of view and automatically adjusts content display based on whether the user is looking at the target object. Content is displayed only when the user's gaze is directed toward the relevant object, creating a dynamic response that enhances user experience by eliminating unnecessary distractions.
Solution Approach 2:
The patent employs feedback mechanisms where the system monitors user gaze direction and uses this information to control content display. The continuous feedback loop between gaze detection and content display adjustment ensures that content is shown only when relevant to the user's current focus, improving ease of operation by reducing cognitive load and visual distractions.
4Measurement precision
If multiple objects are present without viewing cone definition, then object identification is ambiguous, but seamless switching between objects cannot be achieved
Solution Approach 1:
The patent divides the spatial environment into distinct viewing cones, each associated with a specific target object. This segmentation of the visual field allows the system to unambiguously identify which object the user is looking at by determining which viewing cone contains the user's gaze. The segmentation approach enables clear object identification even when multiple objects are present.
Solution Approach 2:
The patent implements dynamic viewing cone management that automatically adjusts and updates viewing cones as the user moves or as different objects enter the field of view. This dynamic adaptation enables seamless switching between objects by continuously recalculating which viewing cone is active, allowing the system to follow the user's attention naturally without manual intervention.

AI summary
A smart glasses viewing area management system and processes for managing content display in smart glasses according to a relationship between a content viewing area and a field of view of a user are disclosed. The smart glasses viewing area management system enables caption glasses to define a viewing cone area for multiple devices with methodology to turn content on or off when a user chooses to focus on an object(s). When a person is watching TV and turns to talk with the person next to them the captions will stop displaying on the caption glasses.
