Vehicle Entertainment Display Segmentation for Driver Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rear-seat entertainment systems for vehicles, rear-seat passengers face difficulties in operating DVD players due to the need for control options to be accessed from the front, which can distract the driver and is unsafe, especially when the remote control is not available or accessible.
Innovation Solution
A system that allows control options to be displayed on a primary display in the front while showing a complete version on secondary displays in the rear, using information adapting means to limit the primary display content to reduce driver distraction, including the use of Optical Character Recognition (OCR) for text and icon translation, and displaying only subpictures or snapshots with control options on the primary display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control options are displayed on the front display to allow driver operation, then ease of operation is improved, but driver distraction increases reducing safety
Solution Approach 1:
The display system is segmented into two distinct displays: a front display for the driver showing only essential control options, and a rear display for passengers showing the complete menu. This segmentation allows each display to serve its specific purpose without compromising safety or functionality.
Solution Approach 2:
Different quality levels of information are provided to different users based on their needs. The driver receives a simplified, safety-critical interface with limited options, while passengers receive the full entertainment menu. This local quality approach ensures the driver is not overwhelmed while passengers maintain full access.
2Device complexity
If control keys are located on the center stack to reduce wiring costs, then device complexity is reduced, but rear-seat passengers cannot operate the system
Solution Approach 1:
The rear display serves multiple functions: it acts as both an entertainment display for passengers and as a control interface for the DVD player. This multi-functionality eliminates the need for separate control keys in the rear, reducing wiring complexity while maintaining passenger accessibility.
3Ease of operation
If the complete menu is displayed on the front display to allow full control, then ease of operation is improved, but driver distraction increases reducing safety
Solution Approach 1:
The information display is segmented into essential control elements for the driver and complete menu content for passengers. The front display shows only critical control options needed for safe driving operation, while the rear display presents the full menu structure and entertainment options.
Solution Approach 2:
The driver is provided with partial access to control functions through a simplified interface showing only essential options. This partial action approach is sufficient for safe operation while eliminating excessive information that would cause distraction, whereas passengers receive the complete menu experience.

AI summary
A vehicle entertainment system is described for reproducing and displaying information and control options. It comprises means for information reproduction (10) and user operating means for selecting one of the control options. There is a primary display (20,50) arranged in the front of the vehicle and at least a secondary display (40) for the rear seat passengers. Information adapting means (60,95) adapt the information to be displayed on the primary display (20,50) to a limited version including the control options. A full version of the information is displayed on the secondary display. In this way, the driver can control the system without being too much distracted by the information and the rear seat passengers see the complete version of the information.
