Mobile Terminal Route Tracking via Position Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor navigation systems do not allow others to track the route followed by a person moving outdoors, leading to delayed searches in case of getting lost.
Innovation Solution
A mobile-side terminal apparatus with a route information storing unit, position acquiring unit, display unit, and position transmitting unit that allows users to share their route and position with another information processing device, enabling real-time tracking of the user's route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation is performed using a mobile phone with GPS function, then the user can continuously navigate from the alighting position to the destination, but another person cannot know the route followed by the user
Solution Approach 1:
The patent introduces another mobile phone as an intermediary device that receives and displays route information. The user's mobile phone (first mobile phone) transmits position data to a second mobile phone, which then displays the route on its display unit. This mediator approach allows route information to be shared without requiring complex modifications to the user's navigation device.
Solution Approach 2:
The patent creates a copy of the route information by transmitting position data from the user's mobile phone to another mobile phone. The second mobile phone displays this copied route information, allowing others to track the user's path without interfering with the original navigation system.
2Reliability
If the user's position is transmitted to another device, then another person can know the route followed by the user, but additional transmission functionality is required
Solution Approach 1:
The patent makes the mobile phone universal by giving it multiple functions: it serves both as a navigation device for the user and as a position transmitter for others to track. The same mobile phone that provides GPS navigation also transmits position data to the second mobile phone, eliminating the need for separate tracking devices.
Solution Approach 2:
The user's mobile phone automatically transmits position information without requiring additional manual intervention. The position acquiring unit continuously obtains location data and the transmitting unit automatically sends this data to the second mobile phone, making the system self-serving and reducing operational complexity.
