Dynamic Display Perimeter for VR Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality (VR) and augmented reality (AR) headsets, light leakage through gaps between the user's face and the display can distract and obscure the user's experience due to the lack of a precise fit, affecting image clarity and overall immersion.
Innovation Solution
The integration of infrared sensors and actuators, such as linear actuators and inflatable balloons, within the headset's perimeter to detect the user's shape and contour, adjusting the fit to minimize light leakage by dynamically matching the display's perimeter to the user's features, using pressure sensors to ensure a comfortable and secure seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display perimeter is fixed and rigid, then the manufacturing precision is improved, but the fit to user's face contour deteriorates causing light leakage
Solution Approach 1:
The display perimeter is transformed from a fixed rigid structure to a dynamic adjustable one using actuators (linear actuators or inflatable balloons) that can change the perimeter's contour in real-time to match the user's face shape, thereby eliminating light leakage while maintaining manufacturing precision of the base structure
Solution Approach 2:
The physical parameters of the display perimeter (position, shape, contour) are changed dynamically through actuator control based on sensor feedback, allowing the perimeter to adapt its geometry to different users' face contours and eliminate gaps that cause light leakage
2Object-affected harmful factors
If the display perimeter is adjusted to fit the user's contour precisely, then light leakage is reduced, but the device complexity increases due to sensors and actuators
Solution Approach 1:
Optical sensors detect the presence and position of the user's face relative to the display perimeter, providing feedback signals that trigger actuators to adjust the perimeter's contour, creating a closed-loop control system that automatically eliminates light leakage without requiring complex manual adjustment mechanisms
Solution Approach 2:
The system performs self-adjustment by using sensors to detect user presence and automatically controlling actuators to optimize the display perimeter fit, eliminating the need for manual intervention or complex external control systems
3Adaptability or versatility
If the display perimeter is adjusted dynamically, then the adaptability to different users is improved, but the ease of operation deteriorates due to automated control
Solution Approach 1:
The display system automatically adjusts its own perimeter configuration based on sensor detection of the user's face, eliminating the need for user operation or manual adjustment, thereby achieving high adaptability while maintaining simplicity in user interaction

AI summary
Example implementations relate to display adjustments. For example, a non-transitory computer readable medium storing instructions executable by a processing resource to sense a contour of an object using a sensor of a display. The instructions can cause the processing resource to determine a contour of a perimeter of the display that fits a portion of the shape of the object. The instructions can cause the processing resource to adjust the perimeter of the display to the determined contour of the perimeter via an actuator of the display.
