Pepper has to propose a fallback
if an expected action from the user
is still missing
WHY?
HOW?
EXAMPLE
www.SoftBankRobotics.com
Fallbacks help users return to a more comfortable flow of
interaction. They avoid failed interactions and ones that come
to a dead end.
Attach a timer to every expected user action. After a few
seconds without user action, Pepper should repeat the
demand. After one or two fallbacks, Pepper should offer to
help or quit the application.
If the user doesn't answer a question, repeat the question
once or twice, then ask if someone is still there. If there's no
reply, Pepper should close the application.
