SOUPS 2023 - An Investigation of Teenager Experiences in Social Virtual Reality from Teenagers', Parents', and Bystanders' Perspectives Elmira Deldari, University of Maryland, Baltimore County; Diana Freed, Cornell Tech; Julio Poveda, University of Maryland; Yaxing Yao, University of Maryland, Baltimore County The recent rise of social virtual reality (VR) platforms has introduced new technology characteristics and user experiences, which may lead to new forms of online harassment, particularly among teenagers (individuals aged 13-17). In this paper, we took a multi-stakeholder approach and investigate teenagers' experiences and safety threats in social VR from three perspectives (teenagers, parents, and bystanders) to cover complementary perspectives. Through an interview study with 24 participants (8 teenagers, 7 parents, and 9 bystanders), we found several safety threats that teenagers may face, such as virtual grooming, ability-based discrimination, unforeseeable threats in privacy rooms, etc. We highlight new forms of harassment in the social VR context, such as erotic role-play and abuse through phantom sense, as well as the discrepancies among teenagers, parents, and bystanders regarding their perceptions of such threats. We draw design implications to better support safer social VR environments for teenagers. View the full SOUPS 2023 program at https://www.usenix.org/conference/soups2023/program
