Smart Glasses Display Control for Visual Range Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices, such as smart glasses, fail to effectively utilize their hardware to facilitate daily life by not adequately addressing visual impairments and the need for enhanced display control, particularly in determining and adjusting image visibility based on user vision and object distance.
Innovation Solution
A method and apparatus for smart glasses that determine the user's visual range and vision characteristics, assess the visibility of objects by capturing eye movements and pixel variations, and display enlarged images of objects not clearly visible, adjusting the display region and scale according to user focus and vision shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the smart glasses display enlarged images of observed objects, then the visibility and detail of distant objects is improved, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The system pre-determines the user's visual range and characteristics before observation occurs. The processor pre-processes images of objects within the visual range, identifying detailed information in advance so that enlargement can be quickly applied when needed without real-time processing delays.
Solution Approach 2:
The smart glasses automatically detect objects containing detailed information within the user's visual range and autonomously determine whether enlargement is needed based on pre-stored visual characteristics. The system self-adjusts the display without requiring manual user input, making the complexity management automatic rather than manual.
2Measurement precision
If the smart glasses continuously monitor and process visual information to determine object visibility, then the accuracy of display control is improved, but the energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system periodically processes visual information by capturing images at specific intervals or when trigger conditions are met (e.g., when an object enters the visual range). The processor alternates between active image processing and idle states, reducing overall energy consumption while maintaining accurate visibility determination when needed.
3Measurement precision
If the smart glasses capture detailed visual characteristics including eyeball rotation and vision direction, then the precision of observed object identification is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The system uses an intermediary image sensor to capture visual characteristics indirectly rather than directly measuring eyeball rotation and vision direction. The image sensor captures images of objects within the visual range, and the processor derives visual characteristics from these images, simplifying the detection process while maintaining precision.
