3D Stereoscopic Display Switching for Driver Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic display devices are not suitable for in-vehicle use as they can impair the driver's visibility with 3D images or movies, necessitating a safety measure to prevent distractions while driving.
Innovation Solution
A 3D stereoscopic display device that detects the state of a moving object, such as a vehicle, and switches between planar and stereoscopic displays to ensure driver safety by adjusting the output of right-eye and left-eye images or videos based on the vehicle's state, using a moving object state detection unit, screen composition processing unit, playback processing unit, and stereoscopic display monitor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If 3D stereoscopic display is provided to the driver during driving, then the driver can obtain more information with depth perception, but the visibility of the screen is impaired and driver safety is compromised
Solution Approach 1:
The display device dynamically switches between 3D stereoscopic display and planar display modes based on the vehicle's operational state. When the vehicle is stationary or in low-speed conditions, 3D display is enabled to provide enhanced information. When the vehicle is in high-speed or active driving conditions, the system switches to planar display to ensure visibility and safety, thus resolving the contradiction between information delivery and driver safety.
2Loss of information
If 3D stereoscopic display with ground objects is provided, then the driver can see detailed environmental information, but the screen visibility is impaired making information illegible
Solution Approach 1:
The system changes the display parameters by switching between 3D stereoscopic mode and planar display mode based on vehicle state. This parameter change allows the system to optimize both information delivery and screen visibility for different operating conditions, preventing the impairment of screen visibility while still providing detailed environmental information when appropriate.
3Adaptability or versatility
If conventional stereoscopic display technology is applied to in-vehicle display, then the driver can watch entertainment content, but safety measures must be taken to prevent distractions
Solution Approach 1:
The display system dynamically adapts its functionality based on vehicle state detection. When the vehicle is stationary or in safe conditions, 3D entertainment content can be displayed. When the vehicle is in active driving conditions, the system automatically switches to planar display mode, thus providing versatile display functionality while maintaining driving safety through dynamic state-based control.

AI summary
Disclosed is a 3Dimension stereoscopic display device including a screen composition processing unit for generating a right-eye image or video image and a left-eye image or video image for planar display or for three-dimensional stereoscopic display of an image or video image, a video image playback device 5 for playing back the images or video images, and a stereoscopic display monitor unit 6 for displaying the images or video images played back by the playback device 5 in a three-dimensional stereoscopic manner, in which the screen composition processing unit 4 switches between outputting the right-eye image or video image and the left-eye image or video image for planar display to the playback device 5 and outputting the right-eye image or video image and the left-eye image or video image for three-dimensional stereoscopic display to the playback device 5 according to state of a moving object.
