 abstract={
           Autonomous service robots in a public setting will generate
           hundreds of incidental human-robot encounters, yet
           researchers have only recently addressed this important
           topic in earnest. In this study, we hypothesized that
           visual indicators of human control, such as a leash on a
           robot, would impact humans' perceptions of robots in the
           context of human-robot encounters. A pilot study (n = 26)
           and a revised study (n = 22) including semi-structured
           interviews (n = 21) were conducted. The interview data
           suggested that the presence of another human during the
           encounter elicited positive reactions from the
           participants. Counter to these interview findings, the
           Godspeed-based survey data yielded largely statistically
           insignificant results between the conditions. We interpret
           this as evidence that traditional HRI survey instruments
           focused on the perception of robot characteristics may not
           be suitable for incidental human-robot encounters
           research. We suggest that human-robot encounters can be
           meaningfully characterized by participants' ability or
           inability to answer implicit questions such as, "what is
           that robot doing here?". We conclude with recommendations
           for human-robot encounters research methods and call for
           research on the intelligibility and acceptability of
           perceived robot purpose during human-robot encounters.
