Virtual Reality (Digital): Technologies
built 295 days ago
Virtual reality technology isn't new. Some of the first high-tech virtual reality systems were aircraft simulators before World War II. But Bailenson is one of the pioneers examining how people behave socially when they're immersed in virtual reality. And some of his team's findings are compelling.

Virtual reality is pioneering a new approach to surgical planning and medical education. The simulation technology is enabling surgeons to practice surgical procedures in immersive and semi-immersive environments. Still, some challenges remain.

At the Intel Developer Forum, held in April in Beijing, EON Reality introduced its EON Human technology, which enables anyone to teleport real images of people into virtual reality. EON Human automatically generates a 3D face and body online from a single picture. The technology allows people to preserve themselves in 3D on the Web for eternity.

Virtual reality (VR) is a technology which allows a user to intereact with a computer-simulated environment. Most virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones. Some advanced and experimental systems have included limited tactile information, known as force feedback.

A second series of ethical questions arise around the issue of the extent to which engagement with virtual reality becomes a distraction from addressing issues of practical reality. There are two dimensions to this. One is the issue of the amount of time that is spent in participating in the virtual, that is taken away from doing one’s personal and civic duties. Once again, precursors can be found in concerns about earlier technologies. The Victorian Catholic Advocate in 19th century Australia expressed serious concerns about popular novel reading because it produced ‘lukewarmness, indifference and neglect of religious duties’ (Askew & Hubber, 1988).

Bailenson got his start with virtual reality at UC Santa Barbara working under psychology Professor Jim Blascovich, with whom he now collaborates. When Blascovich talks about virtual reality, he doesn't limit it to digital technology. Humans have cultivated virtual worlds from the beginning with storytelling and sculpture, theater and books, he said, and more recently with photographs, movies, radio and television.
