Vehicle Display System Resolving Viewpoint Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle display systems struggle to accurately convey visual communication between a vehicle and an object, such as a pedestrian, due to differing viewpoints, leading to potential misrecognition of light patterns projected on the road surface, and fail to notify occupants of objects outside their field of view.
Innovation Solution
A vehicle display system comprising a first display device that projects a light pattern onto the road surface and a second display device inside the vehicle to show the light pattern as viewed from above, either through captured images or computer graphics, allowing the occupant to accurately recognize the light pattern and its positional relationship with the vehicle and objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a light pattern is projected on the road surface to communicate with an object, then visual communication with the object is achieved, but the occupant cannot accurately recognize the light pattern shape due to different viewpoints
Solution Approach 1:
The patent uses a camera to capture an image of the light pattern projected on the road surface and displays this captured image on a display device inside the vehicle. This creates a visual copy of the light pattern as seen from the vehicle's perspective, allowing the occupant to accurately recognize the light pattern shape without being affected by viewpoint differences between the projected light and the occupant's position.
2Reliability
If the light pattern is projected considering the object's viewpoint, then effective communication with the object is achieved, but the occupant cannot recognize the light pattern due to viewpoint mismatch
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures the light pattern from the object's viewpoint and a display device that presents this captured image to the occupant. This intermediary system bridges the viewpoint gap between the object and the occupant, allowing the light pattern to be effectively communicated to the object while simultaneously making it visible and recognizable to the occupant.
3Ease of operation
If the occupant's attention is focused on the road ahead, then safe driving is maintained, but objects outside the field of view cannot be noticed
Solution Approach 1:
The patent transitions the visualization of light patterns from the horizontal road surface plane to a vertical display plane inside the vehicle. By projecting light patterns on the road surface and capturing them with a camera, then displaying these images on an interior display device, the system allows occupants to perceive objects and light patterns in their peripheral or blind zones without shifting their primary attention from the road ahead, effectively utilizing a different spatial dimension for information presentation.
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
This system enables accurate recognition of visual communication between the vehicle and objects, ensuring the occupant is aware of the light pattern's shape and the presence of objects, even if they are outside the occupant's field of view, by providing a clear visual representation of the light pattern and its context.
Implementation Method 1
a first display device configured to emit a light pattern toward a road surface outside the vehicle

AI summary
A vehicle display system is provided in a vehicle. The vehicle display system includes a first display device and a second display device. The first display device is configured to emit a light pattern toward a road surface outside the vehicle. The second display device is located inside the vehicle and is configured to display an image indicating the light pattern as viewed from above.
