Google has unveiled preview of the “Google Wave”. Google Wave is in designing state and it was a developer preview. Google wave is another product from Developed by brothers Lars and Jens Rasmussen and Stephanie Hannon the creator of Google Map.

According to the Lars “Wave is what email would look like if it were invented today”.

It is a combine form of Email and instant messaging with the sharing of images and a lot of other add-ons.

Main Features of Google Wave

Google wave is a HTML5 application. It has a left-hand sidebar “Navigation” and a list of your contacts, from your Google Contacts. As shown in the picture, main part of Google wave is your Google Wave inbox. This is almost looks similar to the Gmail inbox except it shows the faces of contacts who are involved in the various threads. There is also number indication if there is new content in that thread.

By clicking on any threads will open another section to the right of the inbox. This section will show the complete conversation in the threads. If they are re not online, you can send your reply just below their message as you do in the Gmail. In the Google Wave there is no bulky new message creator to pop open, you can simply start typing below the message. Google wave has a interesting feature too if you want to respond to a particular part of their message, you can do that too by starting to type below the part.

If you want to add another friend to the thread, you can do this by going over to your contact box and dragging his/her picture into the there. This is where things really start to get interesting. If that friend wants to get caught up on what everyone else in the wave has already been talking about, they can do so by using the “Playback” feature. This is sort of like rewinding the wave to see what has happened in the past and you can watch it progress through its changes.

But if two of the people involved in the wave are online at the same time, you can talk to each other in real time, all in the same wave. Simply start typing and your friend will see words as you enter them, and vice versa. This is the element that’s like instant messaging obviously, but the key is that it’s just a small part of what potentially makes up a wave conversation. And if you don’t like the idea of real-time communication where the other person can see what you are typing as you type, you can enter a “Draft” mode to hide your words until you’re ready to send them.

And say there is one person in a multi-person thread that you want to message privately. You can easily break-off a private conversation in the wave. Obviously, only you and the other recipient would be able to see this message, but for the both of you it would remain in the flow of the wave itself, keeping it in context.

And from here we go much deeper. Say you want to share some recent photos on Wave, if you have a browser with Gears installed, all you have to do is drag and drop the pictures right into the Wave window.

Google says it would like to see such functionality added to the HTML 5 standards because it really simplifies this type of sharing.

Google isn’t just thinking of Wave as another web app that it creates and you use on one site — it wants you to be able to use it across all sites on the web. Say, for example, you have a blog. As a post, you could share a wave with the public and allow others to see what you and the other people in your wave are doing. And these visitors to your blog could even join in as well right from your blog, and all the information would be placed right into the original wave.
