You once had to leave home to see a psychiatrist for therapy, a music teacher for guitar lessons or a makeup artist for face-to-face consultations. Now they can come to you, virtually, through video chat.

Long the darling of science fiction aficionados, video chat has never much caught on for personal calls. But this year, with the technology being incorporated into a widening array of digital gadgets, professionals specializing in one-to-one services are experimenting with video chat as a way to vastly extend their reach.

Online video chat technology, once the province of geeks and corporate users with IT departments, has become far more user friendly and available. Last month, Apple's iPhone 4 and HTC's Evo 4G phone debuted, both with video chat capability. Selected televisions ……**… now come with built-in cameras for video chat. On computers, Skype, Yahoo Messenger, iChat and other messaging services have offered video chat for several years. But image quality, reliability and user-friendliness have greatly improved over time.

"Previously, people had to be kind of tech-savvy to use video chat," said Alfred Poor, an analyst with research group GigaOm Pro. "Now, with new products coming on the market with video chat already installed, that kind of barrier is no longer there."
GigaOm is so bullish on the technology that it estimates the annual number of video chats will increase from 600 million worldwide in 2008 to 30 billion by 2015.
Susan Fussell, associate professor of communications at Cornell University, doubts that personal calls will be a huge part of that boom if it comes. Crowds famously lined up to see AT&T's Picturephone at the 1964 New York World's Fair, but the technology didn't catch on in homes.
"Back when the Picturephone came out, housewives thought they had to put on makeup and dress up," Fussell said. "No one wants to do that on a day-to-day basis."

The geographic factor is perhaps the biggest attraction for video chat services.
Christian Phoenix was taking guitar lessons when he lived in Huntington Beach, Calif. Then five years ago he moved to Pierre, S.D.
"Guitar lessons were nowhere to be found," said Phoenix, 33, a computer consultant. "There wasn't even a music store nearby."
David Fisher was a guitar teacher who lived in a city with no such shortage.
"There are tons of guitar teachers in Nashville (Tenn.), as you can imagine," Fisher said. He started giving online lessons to "stay afloat and stay competitive."
Now about half of Fisher's students come to him by video chat. Phoenix found him on Craigslist this year and began taking lessons for $35 an hour.
"The main thing with the webcam lessons is that initially you have to get used to it," Phoenix said. "Sometimes you have to zoom so the teacher can see your fingers.

An area that's ripe for video chat expansion is medicine, said market analyst Ken Hyers of Technology Business Research.
"We're seeing a broad push across markets," he said. "The infrastructure is much more able to support it now."
Mental health professionals, who rely on talk and visual cues, have adopted the technology.
In February, during a blizzard on the East Coast, two of psychiatrist Patrick Barta's patients were snowed in and couldn't make it to his Towson, Md., office. In both cases, he suggested video chat sessions.
"I could see their mannerisms and felt safe enough to prescribe them the meds they needed," [Barta said.]
Video chat sessions now account for 20 percent of his practice. Most of these clients are under 35. "The older crowd tends to be more leery of it," Barta said.
