See what I see: Concepts to improve the social acceptance of HMDs

ModularHMD: A Reconfigurable Mobile Head-Mounted Display Enabling Ad-hoc Peripheral Interactions with the Real World

“…To enable asymmetric interaction between HMD and non-HMD users, new HMD compositions have been proposed [8,24,42,57]. HMD Light [79] is a unique mobile HMD with a projector on its top which projects VR content onto the physical floor surface of the environment, where non-HMD users can interact with the projected VR content using their feet (or hands).…”

Frontal Screens on Head-Mounted Displays to Increase Awareness of the HMD Users' State in Mixed Presence Collaboration

“…FaceDisplays enable the bystander to look inside the virtual world on displays mounted around the HMD [17,26,32]. An advantage of such an information display is the transportability [17].…”

“…This risk of excluding the HMD user is gaining attention in the scientific community. Related work proposes different kind of visualization and interaction metaphors, we discuss in more detail in the following chapters [16,17,27,32,38].…”

Public HMDs

“…Further design considerations must be thought through to make the HMD draw attention on its own in order to avoid confusion for the user, as the relation between screen and HMD was not clear at the first point. One possibility to draw attention is to attach displays to the HMD directly in order to create attention or communicate functionality (e.g., [25,35]). However the users' mental model about the value of a public HMD might change in the future, as today HMDs are very novel.…”
