Adjustable Camera Module for AR Headset View Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional head-mounted Augmented Reality (AR) display devices have a fixed camera capturing angle, which limits their functionality to horizontal view scenes and prevents consistent field of view alignment between the user's eyes and the camera, especially in downward, upward, or close-up views.
Innovation Solution
The proposed display device includes an image capturing module with an adjustable position, driven by an electrical machinery unit, and a motion capturing module to track the user's head posture, allowing the image capturing module to adjust its capturing field of view to match the user's field of view across various scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is fixed on the AR glasses, then the device structure is simple, but the capturing angle cannot be adjusted and field of view alignment is poor in multiple scenes
Solution Approach 1:
The patent applies the dynamics principle by making the image capturing module movable rather than fixed. The module can be driven by an electrical machinery unit to adjust its position and capturing angle dynamically, allowing the system to adapt to different viewing scenarios (upward, downward, close-up views) while maintaining field of view alignment between the camera and the user's eyes.
2Adaptability or versatility
If the image capturing module position is adjustable, then the capturing field of view can be adjusted to match user's field of view, but the device complexity increases
Solution Approach 1:
The image capturing module is designed with adjustable position capability, driven by an electrical machinery unit that can move the module to different locations. This dynamic positioning system enables the capturing field of view to be adjusted to match the user's field of view in various scenes, resolving the adaptability issue while accepting the necessary increase in device complexity.
Solution Approach 2:
The patent incorporates a motion capturing module that tracks the user's head posture and provides feedback to the control module. This feedback mechanism allows the system to automatically adjust the image capturing module's position to maintain proper field of view alignment, making the adaptability adjustment more intelligent and reducing the burden on the user to manually configure the system.
3Reliability
If the camera is fixed for head-up scenes, then the device structure is simple, but the field of view seen by user's eyes is inconsistent with the field of view tracked by the camera in multiple scenes
Solution Approach 1:
The patent resolves the field of view consistency issue by making the image capturing module dynamically adjustable. The module can change its position and capturing angle based on the scene requirements, ensuring that the field of view tracked by the camera remains consistent with the field of view seen by the user's eyes whether the user is looking up, down, or at close-up objects.
Solution Approach 2:
The motion capturing module continuously tracks the user's head posture and provides real-time feedback to the control module. This feedback loop enables the system to automatically adjust the image capturing module's position to maintain field of view consistency across multiple scenes, significantly improving reliability while managing device complexity through automated control.

AI summary
A display device, a method, and a non-transitory computer readable medium for modulating capturing view are provided, the display device is wearable on a user's head and includes an image capturing module, a motion capturing module, and a control module; the image capturing module captures an environment image, the image capturing module is movably arranged; the motion capturing module obtains an inclined angle through measuring a posture of the user's head; the control module compares the inclined angle to a predetermined angle, to obtain an angle difference between the inclined angle and the predetermined angle, and controls the image capturing module to move to adjust a position when the angle difference is greater than an angle threshold value, rendering a degree of overlapping of a field of view of the image capturing module and a field of view of the user reaches a predetermined degree of overlapping.
