Systems and methods for selecting an input source for data input to a wireless communication device are provided that allow a wireless communication device to be in active communication with one or more remote devices via wired or wireless links and receive input from a user through a remote device or through the user interface on the wireless communication device. The wireless communication device establishes an input source upon detection of the active communication link with the remote device and thereafter maintains an active input state to preserve a single input source during the session with the remote device. When the user switches the source of input, the wireless communication device detects the new input source, updates the active input state and provides the updated active input state to the remote device. Subsequent input from the new input source is thereafter received and processed and any subsequent input from a previous input source is discarded or buffered as appropriate.
