Mobile Terminal Road Guidance Using User-Defined Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems require complex connections and incur costs and time for map data downloads, and users may be confused by detailed map information provided by map data service providers, necessitating a more convenient and user-friendly road guidance method.
Innovation Solution
A method and apparatus that allows users to create a road guide map using a mobile terminal with a touch screen, where users can input location information and designate specific locations, search for location information, and receive notifications when arriving at those locations, using a GPS module and storage unit to manage map data and location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users download map data through wireless Internet or PC connection, then navigation service can be provided, but data fees and downloading time are incurred
Solution Approach 1:
The system pre-loads and stores essential map data (road names, building names, location information) in the mobile terminal before navigation is needed. This preliminary action eliminates the need for real-time downloading during travel, resolving the contradiction between convenience and downloading time.
Solution Approach 2:
The invention extracts only the essential navigation elements (road names, building names, location information) from complete map data sets. By taking out only what is necessary for navigation rather than downloading entire map databases, the system reduces data fees and downloading time while maintaining navigation functionality.
2Quantity of substance
If detailed map information from map data service providers is used, then comprehensive navigation data is available, but users may be confused by excessive information
Solution Approach 1:
The system extracts and displays only essential navigation information (road names, building names, location data) while filtering out excessive details. This extraction principle maintains comprehensive navigation capability while eliminating information overload that confuses users.
Solution Approach 2:
The invention applies local quality by providing different levels of information detail at different locations and times during navigation. Essential information is always displayed, while additional detailed information is selectively provided only when relevant to the current navigation context, improving user-friendliness without sacrificing comprehensiveness.
3Ease of manufacture
If PC connection and special ports are required for map data transfer, then map data can be received, but connection process becomes complicated
Solution Approach 1:
The system utilizes the mobile terminal's built-in wireless communication capabilities (GPS receiver, wireless Internet) that are already present in modern mobile devices. This universal approach eliminates the need for special PC connections and ports, as the terminal can independently receive and process map data through its existing multi-functional communication interfaces.
Solution Approach 2:
The mobile terminal performs map data acquisition and processing independently using its own built-in resources (GPS receiver, storage unit, processor). This self-service capability eliminates dependency on external PC connections and special ports, simplifying the overall process while reducing device complexity requirements.

AI summary
The present invention relates to apparatus and method for road guidance using a mobile terminal. The method for road guidance using a mobile terminal includes receiving a map image created by a users input, setting at least one user-designated location to the map image according to the users input, setting location information of the user-designated location to the user-designated location, comparing the location information of the user-designated location with current location information of the mobile terminal; and notifying of arrival at the user-designated location. A user may arrive at a desired destination according to the present invention without using map data provided by a map data service provider.
