Christos Kyrlitsias, Despina Michael-Grigoriou
2022 Frontiers in Virtual Reality  
Many of these applications include virtual humans that are classified into avatars and agents.  ...  To be effective, many virtual reality applications require that the users perceive and react socially to the virtual humans in a realistic manner.  ...  Avatars In immersive virtual environments (IVEs), an avatar is the (usually visual) representation of the user in a virtual world.  ...

Effects of Communication Mode on Social Presence, Virtual Presence, and Performance in Collaborative Virtual Environments

Eva-Lotta Sallnäs
2005 Presence - Teleoperators and Virtual Environments  
The particular concern in this thesis is how humans are affected by different multimodal interfaces when they are collaborating with another person in a shared virtual environment.  ...  Another aspect investigated is how different modalities affect people's notion of being present in a virtual environment that feels realistic and meaningful.  ...  It has been both the most exhilarating and agonizing period in my life. I would like to thank a whole bunch of kind and generous people who made this thesis possible.  ...
