Interacting with Pepper
Prerequisite: Autonomous Life: ON
To chat with Pepper :
Tips
- Pepper says nothing, why? If Pepper did not understand what you said, he starts listening again. In this case, you will hear two “bilips” in a row, one when he stops listening, the second when he stats listening again. Repeat lounder or try another sentence.
- Pepper starts talking before I finished, why? Pauses are interpreted as the end of the sentence, so do not hesitate: speak loud and clear, without hesitation.
Calling Pepper
Prerequisite: Autonomous Life: ON
When Pepper 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 Pepper with one of the following sentences:
| English | Effect |
|---|---|
| “Pepper” | Pepper has a small reaction. |
| “Hello”, “Hi” | Pepper has a small reaction. |
| “Come Here”, “Come Closer” | If Pepper is able to see you, he asks for confirmation. If you confirm, Pepper comes closer. |
| “Pepper Come Here”, “Pepper Come Closer” | If Pepper is able to see you, he comes closer. |
Understanding interaction
How Pepper detects humans
Pepper tries, as much as possible, to establish and keep eye contact with people around.
To do so, Pepper:
| A | Looks in the direction of any detected stimulus – sound, movement, touch. |
| B | Checks if this stimulus may correspond to a human.If a human is detected, Pepper tries to keep eye contact with him/her,If not, Pepper goes back to his previous occupation. |
Limits
Pepper does not react to new stimulus:
- When processing a stimulus (i.e. checking if it corresponds to a human). Pepper does not react to other stimuli until he has finished to process the first one.
- When engaged in an Activity or a Dialog. When Pepper is chatting with a human, he always keeps tracking the human until the human has left.
- When Pepper is in the middle of an Activity, all his actions are exclusively defined by the Activity itself.
How I know Pepper is listening
To make sure Pepper is listening, check his eye LEDs, and pay attention to the slight “blip” sounds.
| When the eye LEDs are… | Pepper… |
|---|---|
Navy blue, rotating | is listening. |
Green | has stopped listening.Pepper is processing what a human just said. |
White or pale blue | is not listening, because he:is currently speaking, orhas not detected any human presence. |
Sound feedback
Additionally, slight “bilip” sounds can be heard when Pepper starts and stops listening:
- when starting listening, the sound is ascending,
- when stopping the sound is descending.
