Dynamic User Interface for Entertainment Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for entertainment devices lack feedback mechanisms, leading to user confusion and errors due to complex interfaces and inability to adapt to the current state of the device being controlled.
Innovation Solution
A portable electronic device with a touch-sensitive display and an interface circuit that communicates with an A/V hub to dynamically generate and display a user interface based on device-state information, including virtual command icons relevant to the current and related states of the entertainment device, allowing for intuitive control and reduced errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional remote control interface is used for entertainment devices, then the device can provide comprehensive control functionality, but the user interface becomes complicated and difficult to navigate
Solution Approach 1:
The user interface dynamically adapts its content and structure based on the current state of the entertainment device. The remote control receives state information from the device and automatically reconfigures the displayed options to show only relevant commands for that particular state, making the interface both versatile and easy to navigate.
Solution Approach 2:
The interface changes its parameters (displayed options, layout, available commands) based on the state parameters received from the entertainment device. When the device state changes, the remote control updates the interface parameters to reflect the new context, providing appropriate control options without overwhelming the user with irrelevant choices.
2Device complexity
If a static user interface is used in the remote control, then the interface is simple to implement, but it cannot adapt to the current state of the entertainment device
Solution Approach 1:
The remote control implements a feedback mechanism where it receives state information from the entertainment device and uses this feedback to dynamically adjust the user interface. The interface is no longer static but responds to device state changes, showing only relevant commands and options based on the current context provided by the device.
3Adaptability or versatility
If all possible commands are always displayed in the user interface, then the interface provides complete control options, but it confuses the user with irrelevant options
Solution Approach 1:
The remote control extracts and displays only the relevant subset of commands based on the current device state. Instead of showing all possible commands regardless of context, the interface filters out irrelevant options and presents only those commands that are applicable to the current state, reducing user confusion while maintaining complete control capability when needed.

AI summary
A portable electronic device with a touch-sensitive display (such as a cellular telephone) provides a wireless remote control for an entertainment device (such as a consumer-electronic device). Based on device-state information that specifies a current state of the entertainment device (which is received from an audio/video (A/V) hub that communicates with the entertainment device) and one or more related states of the entertainment device, the portable electronic device may generate a user interface that includes one or more virtual command icons. Note that the one or more related states are related to the current state in a state diagram by corresponding operations that transition the entertainment device from the current state to the one or more related states. Then, the portable electronic displays the user interface on the touch-sensitive display. In this way, the portable electronic device dynamically adapts the user interface.
