Information Display Device Perspective Horizontal Plot Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display devices for navigation, such as ship radar systems, fail to provide a balanced view of overall and detailed information, and do not effectively simulate the user's actual line of sight, leading to a lack of intuitive understanding for the user.
Innovation Solution
An information display device that includes a GNSS receiver, memory, and a controller to simultaneously display a perspective plot section and a horizontal plot section, where the perspective plot section shows information near the user's position in detail and the horizontal plot section provides a wider view, with information displayed according to distance and azimuth in the perspective plot section and fixed in vertical directions, and information displayed in the horizontal plot section based on azimuth, allowing for a natural positional relationship and easy understanding of the user's position and route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single radar image display section is used, then the device complexity is reduced, but the user cannot obtain both detailed near-area information and overall wide-area information simultaneously
Solution Approach 1:
The display screen is divided into two distinct sections: a first radar image display section showing a wide-area view and a second radar image display section showing a near-area view. This segmentation allows simultaneous presentation of both overall situation and detailed information without requiring a single complex display mechanism, resolving the contradiction between information completeness and device complexity.
2Loss of information
If the radar image is displayed from a top-down perspective, then the overall wide-area information is provided, but the user's actual line of sight perspective is not simulated
Solution Approach 1:
Different display perspectives are applied to different sections: the first radar image display section uses a top-down perspective to show wide-area coverage, while the second radar image display section uses a perspective that simulates the user's actual line of sight for near-area details. This local differentiation of display qualities allows each section to optimize for its specific purpose, resolving the contradiction between wide-area coverage and intuitive understanding.
3Ease of operation
If only near-area detailed information is displayed, then the user's perspective is simulated, but the overall wide-area situation is not provided
Solution Approach 1:
The display is segmented into two functional areas: the first section maintains top-down perspective for wide-area context, while the second section adopts user-centric perspective for near-area details. This segmentation enables both wide-area context and perspective accuracy to coexist without compromising either aspect.
4Measurement precision
If information is displayed according to distance and azimuth in perspective view, then detailed near-area information is provided, but the display becomes complex for far-area information
Solution Approach 1:
The display system segments information presentation by distance: the first section uses simplified top-down coordinates suitable for far-area display, while the second section applies complex perspective calculations with distance and azimuth for near-area precision. This segmentation allows the system to use computationally intensive methods only where necessary, resolving the contradiction between measurement precision and device complexity.

AI summary
An information display device is provided. The information display device includes a memory configured to store information along with its position, a display unit configured to display the information, and a controller configured to control the display unit. The controller controls the display unit to simultaneously display first and horizontal plot sections. In the perspective plot section, part of the information is displayed such that its display position in vertical directions becomes higher as a distance from the information display device or a movable body to which the device is mounted, to the position becomes longer. In the horizontal plot section, other part of the information is displayed such that its display position is changed in lateral directions according to an azimuth of the position with respect to the information display device or the movable body, and the display position is fixed in the vertical directions regardless of the distance.
