Dynamic User Interface for Entertainment Devices
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, resulting in a suboptimal user experience.
Innovation Solution
A portable electronic device with a touch-sensitive display that receives device-state information from an A/V hub, generating a dynamic user interface with virtual command icons relevant to the current state of an entertainment device, allowing for intuitive control by restricting icons to only those applicable to the device's current state, thereby enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a comprehensive user interface with all available commands is provided, then the device can control all functionality, but the interface becomes complicated and confuses the user
Solution Approach 1:
The user interface is segmented into context-relevant subsets of commands based on the current device state. Instead of presenting all available commands at once, the system divides the command set into manageable portions that are relevant to the current context, reducing interface complexity while maintaining comprehensive control capability.
Solution Approach 2:
The user interface dynamically adapts its content based on the current state of the entertainment device. The set of displayed commands changes dynamically according to the device state, transitioning from a static comprehensive interface to a dynamic context-aware interface that shows only relevant options.
2Ease of manufacture
If a static user interface is used, then the interface is simple to implement, but it cannot adapt to the current state of the device
Solution Approach 1:
The system implements a feedback mechanism where the portable device receives device-state information from the entertainment device and uses this feedback to dynamically generate appropriate user interfaces. The interface adaptation is driven by continuous feedback about the current device state, enabling context-aware command selection.
Solution Approach 2:
The user interface parameters (such as the set of displayed commands) are changed based on the device state parameters. When the device state changes, the system modifies the interface parameters to reflect the new context, transitioning from a static interface to a dynamically adaptive interface.
3Adaptability or versatility
If all commands are always displayed, then the user has access to all functionality, but the user may make errors by activating wrong functionality
Solution Approach 1:
Different portions of the interface are assigned different qualities of visibility based on their relevance to the current device state. Commands that are appropriate for the current state are displayed with high visibility, while inappropriate commands are hidden or dimmed, creating local quality variations that guide user attention and reduce errors.
4Ease of operation
If the interface dynamically adapts to device state, then the user experience is improved, but the system complexity increases
Solution Approach 1:
The system performs preliminary actions by maintaining a state diagram that pre-defines the relationships between device states and appropriate commands. This preliminary structuring of state-transition knowledge allows the dynamic interface adaptation to proceed systematically, reducing the operational complexity despite the dynamic behavior.

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.
