Mobile Terminal Location Guidance via Real-Time Position Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems on mobile devices primarily focus on road navigation and do not provide intuitive guidance for visually impaired, elderly, or special needs individuals, and lack a method for intuitive assistance from another person.
Innovation Solution
A method involving phone communication between two terminals to request and share position information, displaying a geographic information map, and transmitting guiding information, allowing for real-time position sharing and intuitive direction guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional navigation devices are used, then road navigation is provided, but pedestrian guidance and intuitive direction for visually impaired/elderly users is not available
Solution Approach 1:
The patent applies multi-functionality by enabling a single mobile terminal to serve multiple guidance roles: it can operate as both the guided terminal (receiving voice instructions) and the guide terminal (providing location information), and can adapt to different user needs (visually impaired, elderly, or general navigation) through flexible role assignment between terminals
Solution Approach 2:
The patent implements dynamics by allowing dynamic role assignment between terminals. The first and second terminals can switch roles during the guidance process, and the system adapts the guidance mode (voice guidance, map display, position sharing) based on real-time communication between terminals, making the system flexible for different scenarios
2Ease of operation
If navigation devices provide location information, then position guidance is available, but real-time interaction and intuitive assistance from another person is not provided
Solution Approach 1:
The patent uses phone communication as an intermediary mechanism to enable real-time interaction between terminals. The voice communication channel serves as a mediator that allows the guide terminal to provide intuitive assistance and direction guidance to the guided terminal in real-time, simplifying the overall system architecture while enhancing interactivity
Solution Approach 2:
The patent implements feedback through continuous position information exchange between terminals. The guided terminal sends its location to the guide terminal, which then provides real-time direction guidance based on this feedback, creating a closed-loop communication system that enhances real-time interaction
3Measurement precision
If position information is shared between terminals, then accurate guidance is achieved, but error margins in position transmission may increase
Solution Approach 1:
The patent uses feedback mechanisms where the guided terminal continuously transmits its position information to the guide terminal, which then adjusts its guidance instructions based on this feedback. This iterative feedback loop compensates for potential errors in position transmission by allowing real-time correction and verification

AI summary
A method for guiding location includes commencing a call between a first terminal and a second terminal, the first terminal requesting the collection of location information from the second terminal, receiving the location information of the second terminal and displaying on the first terminal a geographic information map displaying the location information, and the user of the first terminal transmitting to the second terminal direction information that is displayed on the geographic information map. As a result, more intuitive and convenient location guidance is provided.
