Visual Data Encoding for Wireless Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without user interfaces, such as cameras, face challenges in connecting to wireless networks as they cannot input configuration data like SSIDs, security keys, or passwords, especially when a PC is not available for manual input.
Innovation Solution
A mobile device converts configuration data into visually encoded digital data, displaying it as a sequence of colors that a camera sensor can capture and decode to establish a wireless network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a device without user interface (like camera) needs to connect to wireless network, then manual configuration is required, but the device cannot input configuration data independently
Solution Approach 1:
A mobile device serves as an intermediary between the user and the camera. The mobile device displays configuration data (SSID, password) visually and the camera captures this visual information to automatically configure network connection, eliminating the need for the camera to have its own user interface
Solution Approach 2:
The patent replaces the mechanical/electronic input mechanism (keyboard, buttons) with an optical mechanism. Instead of the camera needing physical input devices, the system uses visual display and image capture to transfer configuration data, substituting electronic input with optical communication
2Extent of automation
If configuration data is displayed as visual codes on mobile device, then camera can capture and decode automatically, but the complexity of data encoding and decoding increases
Solution Approach 1:
The mobile device displays configuration data using color changes and visual patterns on its screen. Different colors and patterns represent different parts of the configuration data (SSID, password), allowing the camera to capture and interpret this visual information through color detection and pattern recognition
Solution Approach 2:
The configuration data is segmented into multiple visual elements displayed sequentially or in different regions. The mobile device displays different portions of the configuration data at different times or in different visual patterns, allowing the camera to capture each segment and the decoder to reconstruct the complete configuration

AI summary
A system for establishing a connection between a first device and a wireless network includes a first control module, located on the first device, that receives encoded digital data. The encoded digital data corresponds to a plurality of images displayed sequentially on a display of a second device. Each of the plurality of images corresponds to a different portion of the encoded digital data. A decoder module, located on the first device, converts the encoded digital data into configuration data. The configuration data includes at least one of an identifier of the wireless network, an encryption key associated with the wireless network, and a password associated with the wireless network. The first control module uses the configuration data to establish the connection with the wireless network.
