Every day, millions of users interact in real-time via avatars in online environments, such as massively-multiplayer online role-playing games (MMORPGs). These online environments could potentially be unique research platforms for the social sciences and clinical therapy, but it is crucial to first establish that social behavior and norms in virtual(More)
Computer-mediated communication systems known as collaborative virtual environments (CVEs) allow geographically separated individuals to interact verbally and nonverbally in a shared virtual space in real time. We discuss a CVE-based research paradigm that transforms (i.e., filters and modifies) nonverbal behaviors during social interaction. Because the(More)
The realism of avatars in terms of behavioral and form is critical to the development of collaborative virtual environments. In the study we utilized state of the art, real-time face tracking technology to track and render facial expressions unobtrusively in a desktop CVE. Participants in dyads interacted with each other via either a videoconference (high(More)
During the last half of the twentieth century, psychologists and anthropologists have studied proxemics, or spacing behavior, among people in many contexts. As we enter the twenty-rst century, immersive virtual environment technology promises new experimental venues in which researchers can study proxemics. Immersive virtual environments provide realistic(More)
Non-verbal behaviour, particularly gaze direction, plays a crucial function in regulating conversations and providing critical social information. In the current set of studies, we represented interactants in a shared immersive virtual environment. Interactants sat in physically remote rooms, entered a common virtual room and played games of 20 questions.(More)
The three-dimensional models used to embody intelligent agents are becoming increasingly realistic. We discuss two studies in which we embodied intelligently behaving virtual agents with photographically realistic models of human subjects' heads and faces. We then immersed those subjects with agents embodied with their virtual selves and compared their(More)
As digital communication becomes more commonplace and sensory rich, understanding the manner in which people interact with one another is crucial. In the current study, we examined the manners in which people touch digital representations of people, and compared those behaviors to the manner in which they touch digital representations of nonhuman objects.(More)
E very year in the US alone, more than 42,000 Americans die as a result of 6.8 million automobile accidents. 1 Consequently, driver-safety technology is an active research area in both industry and academia. Pervasive computing environments, with integrated sensors and networking, can provide an ideal platform for developing such technology. Taking(More)
—Despite a variety of new communication technologies, loneliness is prevalent in Western countries. Boosting emotional communication through intimate connections has the potential to reduce loneliness. New technologies might exploit biosignals as intimate emotional cues because of their strong relationship to emotions. Through two studies, we investigate(More)
