Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Head Mounted Displays (HMDs) for virtual displays are expensive, bulky, and require complex orientation sensors, which are inaccurate and need calibration, while there is a need for a low-cost, lightweight, and easily integratable head orientation sensing system optimized for cockpit environments.
Innovation Solution
A virtual display system utilizing a camera and processing system to determine head orientation from a marker image, providing a virtual image that does not obstruct the view through a windshield, using a camera-mounted system with markers and pattern recognition algorithms to calculate head position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional head orientation sensors are used in HMDs, then head orientation can be sensed, but the system becomes expensive, bulky, and complex
Solution Approach 1:
The patent uses a camera to capture images of the environment that contain marker patterns, creating a visual copy of the spatial information. By analyzing the marker positions in these images, the system determines head orientation without requiring complex physical sensors, thus resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent replaces mechanical orientation sensors with an optical system using cameras and image processing. The camera-based system captures visual data of markers in the environment, and software algorithms compute head orientation from these images, substituting mechanical sensing with optical and computational methods to reduce complexity while maintaining accuracy
2Measurement precision
If conventional HMDs with complex orientation sensors are used, then head orientation sensing is achieved, but the cost increases
Solution Approach 1:
The patent employs inexpensive cameras and standard computer vision algorithms instead of costly specialized sensors. The system uses readily available off-the-shelf components that can be easily manufactured and deployed, significantly reducing system cost while maintaining adequate orientation sensing accuracy through software-based marker recognition
3Adaptability or versatility
If conventional HMDs are used, then virtual display is provided, but the system becomes bulky and requires extra display space
Solution Approach 1:
The patent makes the camera serve multiple functions: it captures images for navigation purposes and simultaneously provides data for head orientation sensing and virtual display positioning. This multi-functionality eliminates the need for separate dedicated sensors and reduces overall system volume, as the same hardware component supports multiple operational requirements
