Direct Device Connection via Camera-Based Angle and Location Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for establishing direct connections between electronic devices, such as Wi-Fi Direct and Bluetooth, are inconvenient for users as they often require proximity or QR code scanning, lacking a straightforward way to determine the target device for connection.
Innovation Solution
A method and system that utilize a processing unit, communications interface, positioning unit, and sensor to obtain the location and angle of a first electronic apparatus, collect locations of nearby devices, determine the intended device, and establish a direct connection using these parameters, facilitating a more user-friendly connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If typical pairing methods (QR code scanning or device scanning with UI selection) are used, then devices can establish direct connection, but the pairing process becomes inconvenient and complex for users
Solution Approach 1:
The patent replaces manual pairing operations (QR code scanning, device scanning, UI selection) with an automated optical system. The camera captures the target device's display, and image processing automatically identifies and extracts connection information, substituting mechanical user actions with automated visual recognition systems.
Solution Approach 2:
The system performs self-service by automatically capturing the target device's display through the camera, processing the image to extract connection information, and initiating the connection without requiring user intervention for device selection or code entry. The apparatus serves itself by autonomously completing the pairing process.
2Productivity
If users manually scan and select target devices through UI, then connections can be established, but the process requires significant user time and effort
Solution Approach 1:
The target device prepares connection information in advance and displays it on its screen. The source device's camera is pre-positioned to capture this display, and image processing is initiated automatically. These preliminary actions eliminate the need for real-time user searching and selection, significantly reducing pairing time.
3Adaptability or versatility
If proximity-based pairing is used, then direct connection can be established, but the requirement for physical proximity limits flexibility
Solution Approach 1:
The patent introduces an optical intermediary (camera-based visual recognition system) that mediates the connection process between devices. This intermediary allows connection establishment without direct physical proximity or contact, as the camera can capture the target device's display from a distance, thereby increasing connection flexibility while maintaining simplicity.

AI summary
The invention introduces a method for establishing a direct connection, executed by a processing unit of a first electronic apparatus, which contains at least the following steps. A first location of the first electronic apparatus and an angle of the first electronic apparatus are obtained. Second locations are collected via a communications interface of the first electronic apparatus, where each second location is of a second electronic apparatus. It is determined which of the second electronic apparatuses the first electronic apparatus is aimed at, according to the first location, the second locations, and the angle of the first electronic apparatus. A direct connection is established with the determined second electronic apparatus via the first communications interface.
