Universal Remote Programming via Image Layout Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Programming a universal remote control device to replace a malfunctioning one is cumbersome, requiring users to know appliance type and brand information and often resulting in uncertainty about button functionality.
Innovation Solution
A method using layout properties of the existing remote control device to program a universal remote control device, where a processing circuit outputs queries about the layout and receives responses to identify the device, allowing for precise programming of commands through a decision tree and image or text-based queries, potentially aided by image processing for automatic identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional programming methods using appliance type and brand information are used, then the universal remote control device can be programmed to control specific appliances, but the programming process becomes cumbersome and time-consuming
Solution Approach 1:
The patent captures an image of the existing remote control device and uses image recognition to automatically identify its button layout and mapping. This copying approach eliminates the need for manual programming by replicating the original remote's configuration, thereby maintaining full appliance compatibility while dramatically reducing programming time from minutes to seconds.
Solution Approach 2:
The system enables the universal remote to program itself by automatically recognizing the target appliance through image processing and autonomously configuring the button mappings. This self-service capability removes the burden of manual information entry from the user while ensuring accurate appliance-specific programming.
2Reliability
If traditional programming methods are used, then the remote can be programmed for specific brands, but the user must know appliance type and brand information and experiment with operation
Solution Approach 1:
By capturing and analyzing an image of the existing remote control, the system automatically replicates its button layout and signaling characteristics. This ensures that each button on the universal remote corresponds exactly to its counterpart on the original remote, guaranteeing full functionality without requiring user experimentation or knowledge of appliance specifications.
Solution Approach 2:
The patent replaces the manual mechanical process of programming (where users physically enter codes and test buttons) with an automated optical recognition system. The image processing and pattern recognition algorithms automatically determine the correct button mappings, substituting intelligent automation for manual trial-and-error procedures.
3Adaptability or versatility
If a universal remote control device is bought to replace a broken one, then replacement is possible, but the programming process is cumbersome
Solution Approach 1:
The system simplifies the replacement process by having the user simply point the camera at the broken remote control. The image recognition technology then automatically copies the button layout, identifies the appliance type, and configures all button mappings in seconds, transforming a previously cumbersome programming task into a simple one-step operation.
Solution Approach 2:
The patent introduces an intermediary image processing system that mediates between the universal remote control device and the target appliance. This intermediary automatically translates the visual information from the broken remote into the appropriate programming commands, eliminating the need for users to directly engage in complex programming procedures.
