Designing public VR installations

Virtual Reality (VR) installations using head-mounted displays (HMD) are becoming increasingly popular in public spaces. However, VR's immersive nature engages only the HMD wearer and excludes everyone else in the public space, and there is little design knowledge of how to engage those not wearing an HMD. To address this, we draw from our experiences of having designed seven public VR installations to present a design space around the dimensions of "agency"and "interest"with four user engagement frames to articulate twelve different user roles. To guide designers to support all roles and to transition users between those roles, we complement the design space with a set of design tactics for public VR installations. We hope that these combined contributions will help designers engage more people with VR installations so that ultimately more people benefit from what VR has to offer.
