Head-Mounted Display with Sensor-Driven Dynamic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted displays for augmented reality lack effective mechanisms to ensure comfortable and stable wear, as they often fail to adjust their display position accurately relative to the user's eyes and maintain weight balance, leading to discomfort and potential eye strain.
Innovation Solution
A head-mounted display with a wearable component featuring a display device and sensors, where the display's position is adjusted using a combination of pivoting and sliding mechanisms driven by sensors, including gravity sensors and eye-tracking sensors, to align the display optimally with the user's eyes and maintain weight balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is fixed on the wearable component, then the structure is simple, but the display position cannot be adjusted to align with the user's eyes, causing discomfort and eye strain
Solution Approach 1:
The display device is made movable relative to the wearable component through a pivoting mechanism that allows the display to rotate and adjust its position dynamically, enabling alignment with the user's eyes while maintaining a relatively simple overall structure
Solution Approach 2:
The system uses sensors to automatically detect the user's eye position and automatically adjusts the display device position accordingly, eliminating the need for manual adjustment while keeping the structure simple
2Adaptability or versatility
If the display device is made movable to adjust position, then the display can be aligned with the user's eyes, but the structure becomes more complex
Solution Approach 1:
A pivoting mechanism is introduced that allows the display device to rotate and adjust its position dynamically, enabling the system to adapt to different user eye positions while maintaining a relatively compact and manageable structure
Solution Approach 2:
Sensors detect the user's eye position and provide feedback to the control system, which then automatically adjusts the display device position, enabling high adaptability without requiring complex manual adjustment mechanisms
3Measurement precision
If the display device position is manually adjusted, then the structure remains simple, but the alignment precision with the user's eyes is insufficient, leading to discomfort
Solution Approach 1:
Sensors are used to detect the user's eye position and provide real-time feedback to the control system, which automatically adjusts the display device position with high precision, eliminating the imprecision of manual adjustment
Solution Approach 2:
The system performs automatic self-adjustment by detecting eye position through sensors and autonomously positioning the display device, achieving high alignment precision without requiring user intervention
4Illumination intensity
If the display device is positioned to align with the user's eyes, then visibility is improved, but the weight distribution may become unbalanced, causing shoulder or neck pain
Solution Approach 1:
The display device is made dynamically adjustable not only in position for visibility but also in orientation and weight distribution, allowing the system to optimize both visibility and comfort by balancing the display position with the user's anatomical features
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
