AR-HUD Coordination for Extending Vehicle Driver Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display (HUD) systems have a limited field of view (FoV), which restricts the information that can be displayed to a vehicle driver, necessitating non-AR solutions to convey information outside this FoV, leading to limitations in the augmented reality experience.
Innovation Solution
Coordinating information between a HUD system and an augmented reality device, such as AR glasses, to supplement and extend the FoV by projecting additional information outside the HUD's projection area, adapting it to the device's position and user's gaze, and coordinating the information display dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a HUD system is used to display information to the driver, then information can be projected into the windshield for viewing, but the field of view is limited due to constructional limits of the HUD projector
Solution Approach 1:
The patent combines a traditional HUD system with an augmented reality device (AR glasses) to create a hybrid display system. The HUD projects information onto the windshield within its limited FoV, while the AR device captures this projection and re-projects it along with additional information to extend the effective FoV beyond the HUD's constructional limits.
Solution Approach 2:
The AR device acts as an intermediary between the HUD projector and the driver's eye. It captures the HUD's projection, processes it by adding supplementary information, and re-projects the combined content to a virtual image plane that extends the usable FoV while maintaining compatibility with the HUD's output.
2Loss of information
If the HUD projection area is extended, then more information can be displayed, but the constructional limits of the HUD projector prevent this
Solution Approach 1:
The system transitions from a single-dimension HUD projection to a multi-dimensional display by incorporating the AR device's camera capture, processing, and re-projection capabilities. This adds a temporal and spatial dimension to the information display, allowing content to be extended beyond the original HUD projection boundaries.
Solution Approach 2:
The AR device serves multiple functions: it acts as a camera to capture HUD projections, a processor to add supplementary information, and a projector to re-display the combined content. This multi-functionality enables information extension without requiring a completely new projection system.
3Adaptability or versatility
If additional information is displayed outside the HUD FoV, then the augmented reality experience is enhanced, but non-AR solutions are required which limit the AR experience
Solution Approach 1:
The patent merges the HUD system with an AR device to create a unified augmented reality experience. By integrating the HUD's projection capability with the AR device's capture and re-projection functions, the system delivers enhanced AR functionality while maintaining a consistent virtual image plane, eliminating the need for separate non-AR solutions.
