Abstract - Robots gathering personal information in public spaces often lead users to decide whether to disclose their information to the robot. This paper aims to investigate factors impacting individuals' intention to disclose personal information to a social robot in public spaces and evaluate the actual disclosure during the interaction with the robot. For this purpose, a model is proposed to predict people’s intentions to disclose information to a social robot. We conducted our experiment at a public festival with more than 100 participants using the social robot ARI. The findings reveal the substantial impact of factors including risk beliefs, trusting beliefs, perceived enjoyment, and social influence on the intention to disclose personal information. Moreover, they reveal that although only a small percentage (6.20%) of people had the intention to disclose information to the social robot, most participants (98.00%) finally disclosed their personal information.

Research model

We propose a new research model (see the below figure) to predict users' intention to disclose personal information to a robot.

Pilot study videos

In this video, we will show how the robot interacts with the user.

Questionnaire

We employed a questionnaire to evaluate participants’ intention to disclose personal information as you can download here.
