Driver-Gaze Holographic Surround View for Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surround view systems in vehicles often require driver interaction to change perspectives, leading to distraction and decreased safety due to reduced focus on the road situation.
Innovation Solution
A surround view system utilizing cameras and holographic projection units to project 3D holographic images on vehicle surfaces within the driver's viewing direction, determined by a driver monitoring unit, without the need for manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional display is used to show surround view images, then the driver can see the surrounding environment, but the driver must interact with the display to change perspectives which causes distraction
Solution Approach 1:
The system automatically detects the driver's viewing direction using the driver monitoring unit and autonomously selects which camera images to display, eliminating the need for manual interaction. The system serves itself by adapting to the driver's natural gaze direction without requiring buttons, touch panels, or voice commands.
Solution Approach 2:
The driver monitoring unit continuously monitors the driver's viewing direction and provides real-time feedback to the control unit, which adjusts the displayed perspective accordingly. This closed-loop feedback system ensures the display always shows the most relevant view without requiring driver intervention.
2Adaptability or versatility
If multiple perspectives are made available on a single display, then the driver can assess different situations, but the driver must manually switch between perspectives which reduces focus on the road
Solution Approach 1:
The system dynamically adapts the displayed perspective based on the driver's real-time viewing direction. Instead of offering static perspective options that require manual selection, the system continuously adjusts which camera feed is displayed according to where the driver is looking, making the interface as dynamic as the driver's attention.
Solution Approach 2:
The system prepares multiple camera perspectives in advance and pre-selects the most appropriate one based on predicted driver viewing direction or current gaze data, so that the relevant perspective is already displayed before the driver needs to see it, eliminating the need for switching actions.
3Ease of operation
If the display is positioned centrally in the dashboard, then it is easily accessible, but it requires the driver to shift attention from the road to the display
Solution Approach 1:
The system transitions from a two-dimensional display on the dashboard to a three-dimensional holographic projection that can be positioned in virtual space. By projecting images into the air space in front of the driver or onto the windshield, the system removes the display from the driver's peripheral vision area while maintaining accessibility through natural line-of-sight viewing.
Solution Approach 2:
The holographic projection acts as an intermediary between the camera system and the driver's eyes, presenting information in a way that does not require focusing on a physical display surface. The projection can be positioned at optical infinity or at a comfortable viewing distance, allowing the driver to view surround information without shifting focus from the road.
