Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted devices struggle to adjust their lens transparency, display brightness, and audio output in real-time to user comfort levels based on eye data and ambient conditions, leading to potential user discomfort due to inadequate adaptation to changing environments.
Innovation Solution
Implementing sensors to capture eye data and ambient conditions, allowing for real-time adjustments to lens transparency, display brightness, and audio output, using processing logic to drive transparency modulators, display layers, and audio controls based on user preferences and crowd-sourced data to optimize user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head mounted device uses fixed lens transparency and display brightness settings, then the device structure is simple, but user comfort deteriorates in varying light conditions
Solution Approach 1:
The patent implements dynamic adjustment of lens transparency and display brightness based on real-time eye data and ambient light conditions. The system transitions from fixed settings to adaptive controls that automatically respond to changing environmental conditions and user needs, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The patent employs feedback mechanisms where eye trackers and ambient light sensors continuously monitor user eye state and environmental conditions, feeding this information back to the control system. This enables automatic adjustment of lens transparency and display brightness, achieving adaptability without requiring complex manual intervention.
2Ease of operation
If the head mounted device adjusts settings manually by user, then device complexity is low, but ease of operation deteriorates due to frequent manual adjustments needed
Solution Approach 1:
The patent implements self-service functionality where the device automatically monitors its own performance through eye trackers and environmental sensors, adjusting lens transparency and display brightness without user intervention. This eliminates the need for frequent manual adjustments while maintaining appropriate automation levels.
Solution Approach 2:
The system uses feedback from eye movement sensors and ambient light detectors to automatically adjust display parameters. This closed-loop control enables the device to self-optimize based on real-time conditions, improving ease of operation while maintaining reasonable automation extent.
3Adaptability or versatility
If the head mounted device captures detailed eye data continuously, then adaptability to user comfort is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic sampling of eye data at optimized intervals rather than continuous capture. The system adjusts the sampling rate dynamically based on whether the user is looking at static or moving content, achieving real-time comfort adaptation while reducing overall energy consumption through intelligent periodic action.
Solution Approach 2:
The system dynamically adjusts the frequency and intensity of eye data capture based on current usage conditions. During periods of high adaptability need, the system increases sampling rates; during stable conditions, it reduces sampling frequency, optimizing the balance between adaptability and energy consumption.
