Understanding interaction ¶
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

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.
