IF PUBLIC speaking gives you the willies, the chances are you’ll be just as scared of virtual people, experts have discovered. But in the long run these “avatars” will help you overcome your fears.
Mel Slater at University College London, and his colleague David-Paul Pertaub have developed a VR environment to help people overcome their phobias. In their virtual seminar room, people have to give a presentation to eight computer-generated people who can appear by turns fascinated, bored stiff or just annoyingly neutral.
While it’s not the first time VR has been used to treat phobias, such as fear of spiders or flying, no one knew if the technique could also help people to overcome their social phobias.
To find out, Pertaub watched how people behave in seminars and programmed the virtual people to do the same things: crossing their arms, frowning, yawning and putting their feet on the table. “Our negative audience is very negative,” says Slater.
Then Slater and Pertaub compared the performances of 43 volunteers who gave a talk either to an attentive audience or to an unenthusiastic one. Surprisingly, the subjects responded as if the avatars were real.

According to the passage,
while addressing the virtual audience, the volunteers behaved as if it was real.
the eight computer-generated people reacted negatively to the 43 volunteers ’ talks.
the virtual people seemed to find the subjects of the volunteers ’ talks extremely boring.
Slater and Pertaub were fascinated by the presentations, whereas the virtual audience showed no enthusiasm at all.
the way the subjects reacted when addressing the computer-generated people was no surprise to Slater and Pertaub.
