Wi-Fi Direct Parameter Sharing via Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi Direct connection methods do not effectively consider the sharing of communication parameters between devices using image-based methods, leading to potential connection failures and inefficiencies in determining roles and establishing wireless connections.
Innovation Solution
A communication apparatus with a determination unit to assess whether a partner device can perform image-based communication parameter sharing, and a sharing unit to execute this process using either image-based methods or Wi-Fi Protected Setup (WPS), ensuring secure and efficient wireless connection establishment via Wi-Fi Direct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If image-based communication parameter sharing method is used, then connection speed and user convenience are improved, but compatibility with devices lacking image capture capability deteriorates
Solution Approach 1:
The patent implements dynamic method selection where the communication apparatus adapts its parameter sharing approach based on the capabilities of the partner device. The determination unit dynamically identifies whether the partner device has image capture capability, and the sharing unit dynamically switches between image-based sharing and WPS-based sharing methods accordingly, ensuring both speed and compatibility
Solution Approach 2:
The communication apparatus is designed with multi-functionality to support both image-based communication parameter sharing and traditional WPS-based sharing. This universal design allows the same apparatus to effectively connect with both modern devices capable of image capture and legacy devices that rely on conventional WPS methods
2Device complexity
If role determination is not performed, then connection process is simplified, but connection failures occur due to incorrect role assignment
Solution Approach 1:
The determination unit performs preliminary role determination before the actual connection process. By pre-identifying which device should act as group owner and which should act as client, the system avoids connection failures that would result from incorrect role assignment, while keeping the user interface simple and the overall process transparent
3Adaptability or versatility
If only WPS method is used, then device compatibility is maintained, but connection efficiency and security are reduced
Solution Approach 1:
The system dynamically selects the optimal sharing method based on partner device capabilities. When the determination unit identifies that the partner device supports image-based sharing, the sharing unit activates this more efficient and secure method. Otherwise, it falls back to traditional WPS, thus adaptively optimizing both security and efficiency while maintaining broad compatibility

AI summary
A communication apparatus determines whether the communication apparatus plays a role of capturing an image based on predetermined information indicating whether a communication partner apparatus plays the role of capturing an image in a sharing process executed based on the predetermined information which is supplied to establish from the captured image, and establishes the wireless connection with the communication partner apparatus by Wi-Fi Direct based on the communication parameters shared by the sharing process with the communication partner apparatus in accordance with the determination.
