Heads-up-display system with distributed virtual images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle drivers face difficulties in quickly changing their focus from the roadway to vehicle displays due to increased accommodation time, especially as they age, and existing heads-up-display technologies are limited in displaying virtual images and their locations within vehicles.
Innovation Solution
A heads-up-display system that includes a vehicle computer providing data to multiple display devices positioned at various locations, such as the windscreen, pillars, and dashboard, using LCD panels and lenses to project information, allowing for multiple virtual images to be displayed at different distances and locations within the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a traditional vehicle display is used, then the display can show vehicle information, but the driver experiences increased accommodation time when shifting focus between the road and the display
Solution Approach 1:
The patent applies dimensionality change by projecting the display from a traditional 2D screen onto a 3D virtual space in front of the driver. Multiple display devices positioned at different locations (windscreen, pillars, dashboard) create virtual images at various distances, transforming the flat display into a spatially distributed 3D information environment that reduces focus adjustment time.
Solution Approach 2:
The patent segments the display system into multiple independent display devices positioned at different locations within the vehicle (windscreen, pillars, dashboard). Each display device can show different vehicle information independently, allowing the driver to access segmented information from various locations without moving the head, thereby reducing accommodation time.
2Ease of operation
If a heads-up-display is implemented to reduce accommodation time, then the display can show virtual images at a distance, but the system is limited in the number of virtual images and display locations
Solution Approach 1:
The patent implements universality by making each display device capable of functioning as an independent heads-up-display unit. Multiple display devices can simultaneously create multiple virtual images at different locations and distances, allowing the system to provide both accommodation time reduction and high adaptability for displaying various vehicle information throughout the vehicle cabin.
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
The system reduces accommodation time by allowing drivers to view critical vehicle information without needing to constantly refocus, enhancing safety and usability by providing comprehensive and easily accessible data at various points in the vehicle.
