Gmail Adds Video and Voice Chat

Google announced that it is integrating a voice and video plug-in for it Gmail Chat offering that lets you see or hear the friend with which you are chatting.

image The feature looks cool, and it’s exceedingly straightforward. When you’re in Gmail, your contact list will show a little green camera icon next to any buddy who has a Webcam, is online, and has installed the Gmail Voice and Video Chat plug-in (which works with IE 7, some versions of IE 6, Firefox, Safari, and, of course, Chrome). Click the icon, and you get a chat window with video in the bottom right-hand corner of the Gmail interface. (You can also blow it up to full-screen mode.)

In order to access Gmail Video and Voice Chat, users have to install the voice and video plug-in.Installation is easy and only takes a few seconds to download the plug-in. Once the browser is restarted, a "Video and more" menu will appear at the bottom of the Gmail page. Go to the menu and select "start video chat." It will take a few moments for the video call to connect with your friend.
