This set of competences is the converse of those described in active-animate-spatial-input. As such the PlayMate should be able to respond to the communicative input it receives from animate entities. This means at least being able to produce language and subsequent speech. To make human-robot interactions easier for the human we should also include feedback ouput including looking at the speaker, nodding, etc. It may also be desirable to support the pointing gestures to use in referring expressions.
