Map Display Using Photographic Images for Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation methods on user terminal devices are inadequate for users to navigate through complex roads, especially at night or in poor visibility conditions, as they primarily display moving routes without providing sufficient visual cues.
Innovation Solution
A user terminal device and method that displays photographic images corresponding to a route or direction on a map screen, allowing users to input locations and directions through manipulation, and displays images along the route or in the direction of the route, enabling better navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only a moving route is displayed on the map screen, then the navigation method is simple and easy to implement, but the user cannot find the route when encountering complex roads, nighttime, or poor visibility conditions
Solution Approach 1:
The patent combines the moving route display with photographic images of the route environment. The controller displays both the route line and the corresponding photographic image on the map screen, allowing users to see both the path and the actual visual environment at each location. This merging of route information and visual reference images resolves the contradiction by improving navigation reliability without requiring a completely new system.
Solution Approach 2:
The patent uses photographic images that copy or replicate the actual visual appearance of locations along the route. Instead of requiring the user to physically visit each location, the system displays copied visual representations (photographic images) of the route environment, enabling users to familiarize themselves with the path in advance under various lighting and weather conditions.
2Ease of operation
If photographic images are displayed along the route, then the user can easily navigate through complex roads and poor visibility conditions, but the display complexity increases
Solution Approach 1:
The patent segments the route into multiple discrete locations or points along the path. At each segmented location, a corresponding photographic image is displayed. This segmentation allows the system to manage complexity by processing and displaying images at specific intervals rather than continuously, making the implementation more manageable while still providing comprehensive visual guidance throughout the route.
Solution Approach 2:
The patent adds a visual dimension to the traditional two-dimensional map display. By superimposing photographic images (third dimension of visual information) onto the map screen, the system creates a multi-dimensional display that combines cartographic information with real-world visual references, enhancing navigation ease without completely redesigning the interface.
3Loss of information
If multiple photographic images are displayed at different locations, then the user can view the route in detail, but the information processing time increases
Solution Approach 1:
The patent retrieves and displays photographic images at locations along the route before the user actually needs to navigate to those locations. The system can pre-fetch images based on the planned route and display them in advance, allowing users to review the visual environment beforehand. This preliminary action reduces the time required during actual navigation, as images are already available for immediate display.

AI summary
A user terminal device is provided. The user terminal device includes a display configured to display a map screen, a detector configured to sense a user manipulation, and a controller configured to, when a location and a direction are determined by the user manipulation on the map screen, display at least one photo image corresponding to the location and the direction of the user manipulation on the map screen.
