Mindfulness, which refers to “being present at the moment without judgment through regulated attention,” has become a widely accepted concept for promoting mental wellness. Meditation is one standard method for cultivating mindfulness, often practiced in groups such as within a community or a class. Group settings offer various supports for meditators, such as guidance, post-practice discussions, accountability, and a sense of connection. However, few studies in HCI have explored the use of technology to support group meditation or social interaction among meditators. Social virtual reality (VR) shows promise for facilitating remote meetings and social activities with a strong sense of presence, making it a potential digital support for group meditation and community connection. This thesis presents a qualitative study combining interviews with 13 participants from a meditation community based on social VR and a 4-month participant observation of regular group meditation sessions across different social VR platforms. The findings of this thesis report how the VR meditation community uses social VR to practice mindfulness in a group setting and how its members interact, connect, and support each other. It also explores the benefits of engaging in a meditation community in social VR and identifies challenges that the VR meditation community faces in social VR. The discussions provide implications for using social VR to support the social aspects of mindfulness, as well as suggestions for designers to be aware of and address concerns within social VR as digital mindfulness support.
