  We present the first annotated corpus of nonverbal behaviors in receptionist
interactions, and the first nonverbal corpus (excluding the original video and
audio data) of service encounters freely available online. Native speakers of
American English and Arabic participated in a naturalistic role play at
reception desks of university buildings in Doha, Qatar and Pittsburgh, USA.
Their manually annotated nonverbal behaviors include gaze direction, hand and
head gestures, torso positions, and facial expressions. We discuss possible
uses of the corpus and envision it to become a useful tool for the human-robot
interaction community.
