Display Control Device for Obstacle Approach Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preventive safety technologies may not effectively convey how an obstacle is approaching a mobile object, which can hinder the development of sustainable transportation systems.
Innovation Solution
A display control device and method that acquires surrounding conditions of a mobile object and displays a first image indicating the mobile object's position, a second image indicating an obstacle's position within a predetermined distance, and a third image showing the approaching mobile object and obstacle, with the third image indicating from which side the obstacle is approaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing preventive safety technology displays obstacle position and distance, then basic safety information is provided, but the information on how the obstacle is approaching is insufficient
Solution Approach 1:
The display information is segmented into three distinct visual elements: first image showing mobile object position, second image showing obstacle position, and third image showing approach direction. This segmentation allows comprehensive safety information to be presented without overwhelming the display system, as each element serves a specific informational purpose.
Solution Approach 2:
The patent adds a new dimension to obstacle detection by not only showing position and distance but also indicating the approach direction (from which side the obstacle is approaching). This dimensional addition provides more complete safety information without requiring a completely new display system.
2Reliability
If multiple images are displayed to provide comprehensive obstacle information, then information completeness is improved, but display complexity increases
Solution Approach 1:
The display device is designed to universally present multiple types of safety information through a unified multi-image display system. The same display unit handles position information, distance information, and approach direction information, making the system multi-functional without requiring separate dedicated displays for each type of information.
Solution Approach 2:
The system performs preliminary analysis of obstacle characteristics (position, distance, approach direction) and prepares multiple targeted images before display. This preliminary processing ensures that when information is presented, it is already organized and optimized for safety critical decision-making.

AI summary
A display control device that is one aspect of an embodiment includes an acquirer configured to acquire surrounding conditions of a mobile object, and a display controller configured to cause a display to display a first image indicating a position of the mobile object, a second image indicating a position of an obstacle present within a predetermined distance from the mobile object, which is acquired by the acquirer, and a third image indicating that the mobile object and the obstacle are approaching each other, in which the third image includes an image indicating from which of left and right sides the obstacle is approaching the mobile object.
