Remote Control Mobile Devices via Server Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SOS services for mobile devices only transmit urgent requests for help but do not provide information about the user's emergency situation, limiting their effectiveness in providing assistance.
Innovation Solution
A remote control method and system where a control device, through a server, can remotely control a help-requesting device to acquire information about its surroundings, including audio, video, and location, by transmitting and executing standardized control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If SOS service transmits only urgent request messages, then the service is simple and easy to operate, but no information about the user's emergency situation is provided
Solution Approach 1:
A server acts as an intermediary between the help-requesting device and control devices. The server receives help requests, manages authorization, and relays control commands, thereby enabling information transfer without direct complex interactions between devices.
Solution Approach 2:
The help-requesting device performs multiple functions: it serves as both an SOS alert device and a remote-controlled surveillance device with camera and microphone capabilities, allowing one device to fulfill multiple roles in the emergency response system.
2Reliability
If remote control functionality is added to SOS service, then information about surroundings can be obtained, but the system complexity increases
Solution Approach 1:
The server mediates all control operations by receiving authorization requests, verifying permissions, and relaying control commands between control devices and help-requesting devices, thereby managing system complexity centrally rather than distributing it across multiple devices.
Solution Approach 2:
Authorization is established in advance between control devices and help-requesting devices before emergencies occur. This preliminary authorization setup allows rapid response during emergencies without requiring complex real-time authentication, thereby improving reliability while managing complexity.
3Adaptability or versatility
If multiple control devices are authorized to control help-requesting device, then more people can assist in emergency, but authorization management becomes more complex
Solution Approach 1:
The server centralizes authorization management by maintaining records of which control devices are authorized to control which help-requesting devices. This centralized approach allows multiple control devices to be managed systematically without requiring complex peer-to-peer authorization protocols.
Solution Approach 2:
The authorization system is designed to handle multiple control devices universally through standardized authorization requests and responses, allowing the same authorization mechanism to scale from one to many control devices without increasing complexity proportionally.
Data Source
AI summary
A remote control method between mobile devices and a system thereof are provided. The system includes a server including a control command list for controlling a help-requesting device. The server authenticates a remote control authorization of a control device and relays a data packet communication between the help-requesting device and the control device. The help-requesting device transmits a help request message to the control device through the server. The control device acquires the authorization to remotely control the help-requesting device from the server and then transmits a control command for controlling the help-requesting device to the help-requesting device through the server. The help-requesting device executes the received control command and then transmits execution result data to the control device through the server. The control device outputs the execution result data received from the help-requesting device.
