Wearable Camera Module Stabilization via Gaze and Motion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable augmented reality devices face challenges in capturing images without shaking due to the movement of the device when worn on the user's head, leading to degraded image quality.
Innovation Solution
An electronic device equipped with a camera module, eye-tracking sensor, and motion sensor, where a processor determines the photographing direction based on gaze information and motion information to adjust the camera module's orientation, ensuring images are captured without shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module is fixed in the augmented reality device worn on the user's head, then the device structure is simple, but the captured image shakes due to device movement
Solution Approach 1:
The camera module is designed to be rotatable relative to the housing, allowing dynamic adjustment of the photographing direction. The processor controls the camera module to rotate in response to detected motion, transforming the static camera into a dynamic system that can compensate for device movement and maintain stable image capture.
2Manufacturing precision
If the camera module rotates to compensate for device movement, then image stability is improved, but the device complexity increases
Solution Approach 1:
A motion sensor is introduced as an intermediary component between the device movement and the camera module control. The motion sensor detects device movement and provides feedback to the processor, which then controls the camera module rotation. This intermediary sensing mechanism enables precise compensation without requiring complex direct control systems.
3Measurement precision
If the photographing direction is adjusted based on both motion information and gaze information, then image capture accuracy is improved, but the processing complexity increases
Solution Approach 1:
The system implements feedback control by continuously monitoring both motion sensor data and eye-tracking sensor data, then adjusting the camera module's photographing direction based on this combined feedback. The processor integrates information from multiple sensors and dynamically adjusts the camera orientation to maintain accurate alignment with the user's line of sight while compensating for device movement.
