In-Vehicle Speed Limit Display Using Position-Based Map Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing devices lack the capability to conveniently and reliably provide drivers with real-time legal speed limit information and other essential data, such as traffic conditions and tourist information, without requiring them to divert their attention from the road.
Innovation Solution
An information processing device equipped with sensors for position and map information, communication for legal speed limit and traffic data, and a display system that generates and displays relevant image information, including legal speed limits, traffic conditions, and tourist information, allowing drivers to access this information without taking their eyes off the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display device is provided in the vehicle to display information, then drivers can access legal speed limit and navigation information, but drivers may divert their attention from the road
Solution Approach 1:
The display is positioned at a specific location (windshield or dashboard) with localized information presentation, allowing drivers to access only relevant speed limit and navigation information without being overwhelmed by unnecessary data, thus maintaining attention safety while providing essential information
2Ease of operation
If information is displayed on the windshield or dashboard, then drivers can see information without moving their line of sight, but the display may obstruct the driver's view of the road
Solution Approach 1:
The display utilizes variations in color, brightness, and contrast to present information in a way that is visible to drivers without creating harsh visual obstructions. The display can adjust its visual properties to blend with the surrounding environment while maintaining information legibility
Solution Approach 2:
The display is positioned in the three-dimensional space of the vehicle interior (windshield or dashboard surface) rather than blocking the driver's direct line of sight to the road, utilizing spatial arrangement to provide information without obstruction
3Loss of information
If the display shows detailed navigation information, then drivers can plan routes and notice speed limit changes, but the information may be too complex to process quickly
Solution Approach 1:
The navigation information is divided into separate segments: current legal speed limit, upcoming speed limit changes, and route guidance. Each segment is displayed independently and can be accessed or updated without requiring the driver to process all information simultaneously, reducing cognitive load and processing time

AI summary
A novel information processing device that is highly convenient or reliable is provided. The information processing device includes a sensor portion, a communication portion, a display portion, and an arithmetic device; the sensor portion has a function of obtaining position information, and the communication portion has a function of obtaining map information and legal speed limit information. The arithmetic device identifies first legal speed limit information from the map information on the basis of the position information, the arithmetic device generates first image information including the first legal speed limit information, and the display portion has a function of displaying the first image information.
