|Autonomous Life: ON|
When NAO has not yet seen you, or is not close enough to be fully listening, he may, however, understand a few words.
Speaking loud enough to be heard, call NAO with one of the following sentences:
|“NAO”||NAO has a small reaction.|
|“Hello”, “Hi”||NAO has a small reaction.|
|“Come Here”, “Come Closer”||
If NAO is able to see you, he asks for confirmation.
If you confirm, NAO comes closer.
|“NAO Come Here”, “NAO Come Closer”||If NAO is able to see you, he comes closer.|
How NAO detects humans¶
NAO tries, as much as possible, to establish and keep eye contact with people around.
To do so, NAO:
|A||Looks in the direction of any detected stimulus - sound, movement, touch.|
Checks if this stimulus may correspond to a human.
NAO does not react to new stimulus:
When processing a stimulus (i.e. checking if it corresponds to a human).
NAO does not react to other stimuli until he has finished to process the first one.
When engaged in an Activity or a Dialog.
When NAO is chatting with a human, he always keeps tracking the human until the human has left.
When NAO is in the middle of an Activity, all his actions are exclusively defined by the Activity itself.
How I know NAO is listening¶
To make sure NAO is listening, check his eye LEDs, and pay attention to the slight “blip” sounds.
Eye LEDs feedback¶
|When the eye LEDs are ...||NAO is ...|
|Navy blue, rotating||listening.|
|Green||not listening anymore, he is processing what the human just said.|
|White or pale blue||not listening, the dialog has not started.|
Additionally, slight “bilip” sounds can be heard when NAO starts and stops listening:
- when starting listening, the sound is ascending,
- when stopping the sound is descending.
