A social robot operating in a public space can potentially gather and analyse large quantities of personal information, in the same way as popular social media platforms and digital assistants deployed on many smart phones do. However, a user can choose to not visit a social platform or use a digital assistant and choose to not give consent to its stated terms of use, thereby giving users high degree of control on what is willingly shared. To fill the gap, this study investigates two fundamental issues: i) are users willing to share personal information with a social robot in a public space? and ii) what kind of information are end-users willing to share? In this study a questionnaire-based assessment with potential end-users is carried out, and the insight from these findings will inform the use case development when piloting first prototype of social robot in public space. The primary purpose of this study is to seek information on the expectation and perceptions of end-users, including negative attitudes, towards social robots in public spaces. From the survey result it can be deduced that the predominant concern from the end-users are mainly related to a design aspect, where one challenge will be to design a social robot or the concept surrounding the robot in a way that it informs and reassures users that a social robot deployed in public space is safe and secure.
