A Persuasive Hand Sanitizer Robot in the Wild

摘要

In this paper, we report on field tests of a hand sanitizer robot, which tracks people's movements using gaze and which uses several different persuasive utterances when people are approaching. Our results show that adding speech made people significantly more aware of the opportunity of using hand sanitizer, but that people do not use the hand sanitizer more often than with eye gaze only. Furthermore, the different utterances themselves did not lead to significant differences in attention or use, in spite of their effectiveness in other situations.
