Robot navigation in crowded public spaces is a complex task that requires addressing a
variety of engineering and human factors challenges. These challenges have motivated a …

Many researchers use Wizard of Oz (WoZ) as an experimental technique, but there are
methodological concerns over its use, and no comprehensive criteria on how to best employ …

The role of robots in society keeps expanding and diversifying, bringing with it a host of
issues surrounding the relationship between robots and humans. This introduction to human …

In the context of a growing interest in modelling human behavior to increase the robots'
social abilities, this article presents a survey related to socially-aware robot navigation. It …

We present a novel approach for detecting social interactions in a crowded scene by
employing solely visual cues. The detection of social interactions in unconstrained scenarios …

When should service staff initiate interaction with a visitor? Neither simply-proactive (eg talk
to everyone in a sight) nor passive (eg wait until being talked to) strategies are desired. This …

To enable situated human–robot interaction (HRI), an autonomous robot must both
understand and control proxemics—the social use of space—to employ natural …

People meeting a robot for the first time do not know what it is capable of and therefore how
to interact with it—what actions to produce, and how to produce them. Despite social …

We conducted a 2x2 between-subjects experiment to examine the effects of two orientation
and two gaze behaviors during group conversations for a mobile, low degree-of-freedom …

In this work, we discuss a set of feature representations for analyzing human spatial
behavior (proxemics) motivated by metrics used in the social sciences. Specifically, we …
