Remote Control Interface Menus for Multi-Appliance Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Universal remote controls become increasingly complex as more appliances are controlled, leading to diminished usability due to cluttered interfaces and the need for more keys to manage control codes.
Innovation Solution
A hand-held electronic device with a remote control application that simplifies the user interface by displaying operational mode information, using a PDA with built-in IR transmission capabilities and Web-hosted services for code updates and customization, allowing for intuitive control of multiple appliances through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more keys are added to control more appliances, then the control capability is improved, but the user interface becomes cluttered and usability diminishes
Solution Approach 1:
The patent transitions from a two-dimensional physical keyboard layout to a three-dimensional hierarchical menu structure. Instead of adding more physical keys, the system uses virtual menus with multiple levels and categories to organize control functions, effectively adding a dimensional layer to the interface architecture.
Solution Approach 2:
The control interface is segmented into distinct functional categories (e.g., power control, volume control, channel control, appliance-specific functions). Each category is presented as a separate menu section, allowing users to access only the relevant controls for their current needs rather than navigating a cluttered comprehensive keyboard.
2Adaptability or versatility
If more keys are added to control more appliances, then the control capability is improved, but the device complexity increases
Solution Approach 1:
The remote control device is designed with universal functionality to control multiple types of appliances (TVs, VCRs, DVD players, cable boxes, satellite receivers) through a single unified interface. The hierarchical menu system provides appliance-specific control sets that are activated based on user selection, allowing one device to perform the functions of multiple specialized remotes without requiring separate physical keyboards for each appliance type.
3Ease of operation
If the user interface is simplified, then the usability is improved, but the number of controllable operations decreases
Solution Approach 1:
The user interface is designed to be dynamic and adaptive rather than static. The hierarchical menu structure reconfigures itself based on user selections and appliance types. When a user selects a specific appliance category, the interface dynamically displays only the relevant control options for that appliance, providing a simplified view that adapts to the current context while maintaining access to the full range of functions through the hierarchical structure.

AI summary
A hand-held electronic device having a remote control application user interface that functions to displays operational mode information to a user. The graphical user interface may be used, for example, to setup the remote control application to control appliances for one or more users in one or more rooms, to perform activities, and to access favorites. The remote control application is also adapted to be upgradeable. Furthermore, the remote control application provides for the sharing of operational mode information.
