User interface based on system-state information
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.
