Navigation Code Transfer for Seamless Route Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems require users to perform complex operations to input destination information into portable terminals when transitioning from vehicles to destinations on foot or using public transportation, limiting convenient route guidance.
Innovation Solution
A route guidance method that uses a navigation apparatus to generate and display a code containing destination and current position information, which is captured by a portable terminal to provide route guidance without the need for manual input or position detection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable terminal is used for route guidance from parking lot to destination, then route guidance capability is provided, but complicated and troublesome operations are required to input destination information
Solution Approach 1:
The patent uses a portable terminal to capture an image of the route guidance information displayed on the navigation apparatus screen. The portable terminal then processes this captured image to obtain route guidance instructions, eliminating the need for manual input operations while maintaining full route guidance functionality.
Solution Approach 2:
The patent introduces an intermediary system where the navigation apparatus displays route information on its screen, the portable terminal captures this visual information through image sensing, and then processes the captured image to provide route guidance. This intermediary visual transfer mechanism eliminates direct manual input requirements.
2Ease of operation
If navigation apparatus is operated to store destination as registered point in server, then route information can be acquired, but user must manually enter destination information when leaving car
Solution Approach 1:
The navigation apparatus preliminarily displays the route guidance information on its screen before the user leaves the vehicle. The portable terminal captures this pre-displayed information through image sensing, allowing the user to transfer destination and route information without manual input operations, thus saving time and effort.
3Adaptability or versatility
If portable terminal has GPS and route guidance capability, then route guidance can be provided, but user must perform complicated operations to input information
Solution Approach 1:
The portable terminal uses its image sensing capability to capture the route guidance information displayed on the navigation apparatus screen. This visual copying method allows the portable terminal to obtain route guidance data without requiring manual input operations, while still providing full route guidance functionality using its existing GPS and processing capabilities.
Data Source
AI summary
A route guidance method provides route guidance from a current position to a destination by using a navigation apparatus capable of displaying a route from the current position to the destination in combination with a portable terminal carried by a user. The navigation apparatus produces a 2-dimensional code based on information associated with the destination and a location at which the user leaves his/her car en route to the destination and displays the thus produced code. The portable terminal acquires the information associated with the location at which the user leaves his/her car and the destination by reading the 2-dimensional code displayed by the navigation apparatus.
