Context-Sensitive Remote Control with Dynamic Button Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control devices for multi-modal entertainment systems are complex, requiring users to understand specific commands for each device, leading to user frustration and confusion.
Innovation Solution
A remote control device with a keypad and control module that operates in multiple states, highlighting relevant buttons based on the current state, using a light source and communication protocols like Bluetooth or RF to synchronize with playback devices, and incorporating motion detectors for user interaction detection.

Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional controller includes dozens of keys for controlling multiple devices, then the controller can control various devices, but users find it frustrating and confusing to understand which commands apply to each device
Solution Approach 1:
The controller segments the full set of buttons into multiple context-specific subsets, each displayed based on the current operating state. Instead of showing all buttons simultaneously, the controller divides the interface into relevant portions, reducing cognitive load while maintaining comprehensive functionality across multiple devices.
Solution Approach 2:
The controller dynamically changes the displayed button subset based on the current operating state. The interface transitions between different configurations of visible buttons depending on which device or function is active, making the controller adaptable to contextual needs rather than static.
2Adaptability or versatility
If a remote control device operates in multiple states with different control functions, then it can control different devices appropriately, but the interface complexity increases
Solution Approach 1:
A single controller unit serves multiple functions across different operating states without requiring separate controllers for each device. The same physical controller adapts its interface to provide context-appropriate controls, eliminating the need for multiple specialized controllers while maintaining simplicity.
Solution Approach 2:
Different subsets of buttons are highlighted or made visible depending on the local context or operating state. Rather than uniformly displaying all buttons in all states, the controller applies different visibility qualities to different button subsets based on their relevance to the current state.

AI summary
Various implementations include approaches for controlling content via a playback device. In a particular implementation, a remote control device includes: a keypad having a set of actuatable buttons for controlling a playback device; and a control module, where the remote control device is operable in a plurality of different operating states, and where the control module is configured to highlight one or more distinct subsets of the set of actuatable buttons at the keypad based upon a current operating state of the remote control device.
