Pilot Study of Person Robot Interaction in a Public Transit Space

This paper describes a study of the effect of a human interactive robot placed in an urban transit space. The underlying hypothesis is that it is possible to create interesting new living spaces and induce value in terms of experiences, information or economics, by putting socially interactive mobile agents into public urban transit area. To investigate the hypothesis, an experiment was carried out at a bus terminal serving both a transit space and a shopping mall, where an autonomous robot were to detect and follow random people. The people that were followed were asked to fill our a questionnaire for quantitative analysis of the experiment. In addition video documentation of the experiment was used in the evaluation. The results showed that people were generally positive towards having mobile robots in this type of environment where shopping is combined with transit. However, it also showed harder than expected to start interaction with commuters due to their determination and speed towards their goal. Further it was demonstrated that it was possible to track and follow people, who were not beforehand informed about the experiment. The evaluation indicated that the distance to initiate interaction was shorter than would be expected for normal human to human interaction.
