A remotely controlled device receives touch input data from a remote controller that includes a touch screen. The remotely controller device interprets the touch input data in combination with a current context of the GUI to determine an appropriate command for the current context of the GUI, and updates the GUI in response to the appropriate command. Further, the remotely controlled device sends information via a bidirectional communication protocol to the remote controller informing the remote controller of a context displaying a keyboard, and the remote controller is configured to display a keyboard on its touch screen in response to the information sent via the bidirectional communication protocol.
