Terminal Device Control via Connected Device Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling terminal devices are limited by OS restrictions, preventing direct control of certain applications, especially when the device is out of the user's sight, leading to incomplete functionality and improper control.
Innovation Solution
A control method that uses a connected device to intermediate between the terminal device and the restricted application, transmitting instructions via different communication protocols to enable operation of the second application from the first application, even when direct control is prohibited by the OS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct control of the second application is implemented, then the terminal device can be properly controlled even when out of sight, but OS restrictions prevent this direct control
Solution Approach 1:
The patent introduces a first application as an intermediary between the user and the second application. The first application receives user inputs and transmits control instructions to the second application indirectly through the OS, bypassing the restriction that prevents direct control. This mediator approach enables control of the second application while maintaining OS security models.
2Object-affected harmful factors
If the terminal device is placed out of user sight for safety, then user safety is improved, but the user cannot properly control the terminal device
Solution Approach 1:
The first application serves as a mediator that receives control inputs from the user and translates them into instructions for the second application. This allows the user to control the terminal device without needing to visually focus on the device, as the control interface can be presented in a safer location or format.
Solution Approach 2:
The patent replaces direct visual-mechanical interaction (user looking at and touching the device) with an indirect control mechanism where the first application mediates between user input and the second application's functions, enabling control through alternative interfaces or methods.
3Reliability
If OS restrictions are enforced to maintain system security, then system stability is improved, but application functionality is limited
Solution Approach 1:
The first application acts as a compliant intermediary that operates within OS security boundaries while enabling extended functionality. It receives control inputs and generates appropriate instructions for the second application, maintaining system security protocols while achieving application functionality that would otherwise be restricted.
Solution Approach 2:
The control functionality is segmented into two separate applications: the first application handles user input and control logic, while the second application executes specific functions. This segmentation allows each application to operate within its own security context while achieving integrated functionality through inter-application communication.
Data Source
AI summary
In a control method of a terminal device which includes an OS, a first application, and a second application installed in the OS as a default function which is included in the OS, a first instruction is transmitted by the first application to a connected device. The first instruction is related to an operation of the second application. A second instruction transmitted by the connected device on the basis of a content of the first instruction is received by the terminal device. The second application operates on the basis of the second instruction.
