Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth connection methods are inconvenient, especially in environments with multiple devices, as they require users to search and select connection targets manually, which is time-consuming and cumbersome, particularly for devices with limited input interfaces like glasses-type terminals.
Innovation Solution
A Bluetooth connection method based on relative angle estimation, where devices estimate relative angles using packets received from potential connection targets, determine the target device based on these angles, and establish or reestablish connections automatically when the relative angle changes, allowing for intuitive and convenient wireless connections.

Engineering Contradiction Analysis
1Loss of time
If manual search and selection of Bluetooth devices is used, then connection can be established between devices, but it takes a lot of time for a user to identify and select a communication target
Solution Approach 1:
The system performs preliminary angle estimation and device identification before the user needs to connect. By continuously monitoring the angular positions of surrounding Bluetooth devices and pre-identifying the most suitable connection target based on angle criteria, the system eliminates the time-consuming manual search process when connection is needed.
Solution Approach 2:
The connection system automatically identifies and selects the optimal communication target without requiring manual user intervention. The device autonomously monitors angular positions, evaluates potential connection targets based on predefined angle criteria, and initiates connections automatically, making the system serve itself rather than requiring user operation.
2Ease of operation
If manual device selection is required, then connection can be established, but the operation becomes cumbersome especially for devices with limited input interfaces like glasses-type terminals
Solution Approach 1:
The Bluetooth connection system automatically performs device identification and selection without requiring user input through complex interfaces. The device autonomously monitors angular positions of surrounding devices, evaluates them based on predefined angle criteria, and initiates connections automatically, eliminating the need for manual search and selection operations.
Solution Approach 2:
The patent extracts the manual search and selection operations from the connection process. By removing the need for users to manually search through device lists and make selections, the system simplifies the interface requirements while maintaining connection functionality through automated angle-based target identification.
3Productivity
If conventional Bluetooth search procedure is used, then devices can be connected, but it is inconvenient in environments with multiple devices
Solution Approach 1:
The system performs preliminary monitoring and evaluation of surrounding Bluetooth devices based on angular positions before connection is needed. By continuously tracking the angular positions of multiple devices and pre-identifying the most suitable connection target according to angle criteria, the system enables rapid connection establishment in multi-device environments without requiring manual search procedures.
Solution Approach 2:
The system continuously monitors and updates the angular positions of surrounding Bluetooth devices, using this feedback information to dynamically identify the optimal connection target. The angle-based feedback mechanism allows the system to adaptively select connection targets in multi-device environments, improving both connection efficiency and user convenience.

AI summary
Disclosed herein are a Bluetooth connection device and method based on estimation of a relative angle. The Bluetooth connection method based on estimation of a relative angle is performed by a Bluetooth connection device based on estimation of a relative angle, and includes estimating relative angles using relative angle estimation information included in packets received from one or more communication target devices that are scanned for a Bluetooth connection, determining a communication target device with which a communication link is to be established based on the estimated relative angles, and establishing a communication link through a Bluetooth connection to the determined communication target device, and reestablishing the communication link to any one of additional communication target devices, relative angles of which have been estimated, depending on a change in a relative angle to the communication target device with which the communication link has been established.
