Short-Range Wireless Connection via Visual Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of Bluetooth devices increases, especially in crowded areas, the traditional method of selecting a device through a list of available Bluetooth devices becomes cumbersome due to the difficulty in identifying and selecting the desired device, particularly when devices have similar or identical names or addresses.
Innovation Solution
A short-range wireless communication apparatus and method that captures an identifiable image of a target device, recognizes the corresponding information, and establishes a connection using a camera unit, control unit, and short-range communication unit, allowing for visual identification and selection of the target device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of Bluetooth devices increases, then the coverage and availability of wireless communication improves, but the difficulty of identifying and selecting the desired device increases
Solution Approach 1:
The patent introduces visual identification (image dimension) in addition to traditional audio/list-based identification. The camera captures an image of the target device's display, which shows visual cues like device name, address, and connection status. This adds a spatial/visual dimension to the selection process, allowing users to identify devices by seeing their visual representation rather than just hearing or reading names in a list.
Solution Approach 2:
The patent introduces an image as an intermediary between the user and the target device. Instead of directly selecting from a list of device names, the user captures an image of the target device's display, which serves as a visual mediator containing identification information. This intermediary image makes it easier to distinguish the target device among multiple devices by providing visual evidence of the device's identity and status.
2Ease of manufacture
If devices use similar or identical names or addresses, then device naming simplicity improves, but the accuracy of device identification deteriorates
Solution Approach 1:
The patent captures additional identification dimensions by taking a visual image of the device display. The image contains not just the device name but also the device address, connection status, and visual representation of the device interface. This multi-dimensional visual information allows accurate differentiation of devices even when they have similar names, as the complete display content including address and status provides unique identification.
Solution Approach 2:
The patent creates a visual copy (image) of the target device's display information. This image copy contains the device name, address, and other identification details exactly as shown on the target device's screen. By capturing and analyzing this visual copy, the system can accurately identify the target device based on its displayed information, resolving ambiguities that exist in the physical device appearance or simple naming.
3Device complexity
If traditional list-based selection method is used, then system complexity remains low, but the time required for device selection increases
Solution Approach 1:
The patent performs preliminary action by capturing the target device's display image before the actual connection is established. The image capture and analysis happen in advance, allowing the system to pre-identify and pre-select the target device based on visual information. This preliminary visual identification eliminates the need for time-consuming browsing through connection lists during the actual connection process, significantly reducing selection time.
Solution Approach 2:
The patent replaces the mechanical/manual process of browsing through connection lists with an automated image recognition system. Instead of manually scrolling through and selecting device names from a list, the system automatically captures the target device's display image, recognizes the device information through image processing, and automatically establishes the connection. This substitution of automated visual recognition for manual list navigation dramatically reduces selection time while adding minimal complexity.

AI summary
A short-range wireless communication apparatus and method establish a connection thereof by simply selecting a connection target through a camera and providing an identifiable image of a target. In the method, the apparatus captures an identifiable image of a connection target device and recognizes identifiable information corresponding to the captured identifiable image. Then the apparatus either automatically selects or in conjunction with user approval selects the connection target device corresponding to the recognized identifiable information and establishes a connection with the selected target device through a short-range wireless communication.
