Control Device Automatic Terminal Selection via Directional Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote device control technologies are cumbersome for users to select the appropriate device to control, as the process of identifying and choosing a device is complex.
Innovation Solution
A method and apparatus that allow a control device to easily select a terminal device by transmitting a search request for location and direction information, receiving responses, determining controllable devices based on the responses, and controlling them, using GPS, IPS, and network protocols like UPnP and ZigBee.

1Ease of operation
If a user manually selects a terminal device from multiple available devices, then the control function can be performed, but the operation process becomes complicated and time-consuming
Solution Approach 1:
The control device automatically determines the target terminal device by acquiring location information and calculating direction angles without requiring manual selection by the user. The system performs self-service device identification by comparing the direction angle of each terminal device with the direction the control device is facing, automatically selecting the terminal device that matches the user's intended target based on spatial orientation.
2Ease of operation
If location information is acquired to enable automatic device selection, then device selection is simplified, but additional information processing requirements increase
Solution Approach 1:
The patent replaces manual mechanical selection operations with automated computational processes. The control device uses location information acquisition modules and direction calculation algorithms to automatically identify terminal devices, substituting the mechanical action of manual device selection with an automated information processing system that calculates direction angles and compares them with device orientations.
