Navigation Device Remote Control via Telematics Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices face difficulties in receiving input information from users other than the intended user, limiting remote operation capabilities.
Innovation Solution
A navigation system comprising a navigation device, a telematics server, and a computer that enables remote control operations through a network, allowing another user to instruct and control the navigation device via a telematics server that intermediates input-output information, converting remote control operations into instructions executable by the navigation device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional navigation devices are used with manual operation, then the device can guide routes accurately, but another user cannot remotely control the device
Solution Approach 1:
A telematics server is introduced as an intermediary between the navigation device and the remote control device. The server receives remote control operations from a user's terminal, converts them into executable instructions, and transmits them to the navigation device. This mediator approach enables remote control functionality without directly modifying the navigation device's internal structure, thus improving adaptability while managing complexity through a separate service layer.
2Ease of operation
If the navigation device requires manual input from the user, then operation control is simple, but another user cannot operate the device remotely
Solution Approach 1:
The navigation device is designed to accept operations from multiple sources: manual input from the primary user and remote control operations from other users via the telematics server. The device maintains its original simple operation interface while adding universal compatibility with remote control signals, enabling both single-user simplicity and multi-user versatility through a unified operation handling system.
3Productivity
If remote control operations are implemented without a server, then system complexity is reduced, but operation conversion and transmission cannot be achieved
Solution Approach 1:
The telematics server serves as a centralized intermediary that handles the complex tasks of receiving remote control operations, converting them into executable instructions, and transmitting them to the navigation device. This architecture improves remote operation efficiency by centralizing the conversion logic in the server rather than embedding it in the navigation device, thereby maintaining device simplicity while achieving sophisticated remote control functionality.

AI summary
Provided is a navigation technique which allows a person other than a user who received a route guide to operate a navigation device through an interaction process. The navigation device is characterized by being provided with an instruction reception unit, a process unit, and an output unit. The instruction reception unit receives an instruction for a process from an external device. The process unit executes a process in accordance with the instruction received by the instruction reception unit. The output unit outputs output information which is obtained as the result of the process executed by the process unit.
