SAN FRANCISCO - What do I do with Google Gmail in normal browsers, five years ago, he expected to do again with the new mobile version of its web interface email.

Vic Gundotra, who leads Google mobile software development and communications efforts, showed a web-based applications “technical prototype” on Friday in an interview here on the stage at Web 2.0 Expo. Google offers Gmail applications that run natively Android and BlackBerry mobile phones, but the company is clearly high hopes for the web version as well.

Creating a Web interface means Google can reach more phones easier, Gundotra said, as phone browsers get more sophisticated, and their connection to the Internet is getting better. “Imagine if you could build an application that had been held in all of these phones”, Gundotra said.

As with similar demonstrations in February, Gundotra show version works on iPhone and on the phone using Google Android in the operating system - apparently, HTC Magic.

The program builds on the features in HTML 5 is still under-development version of the technology that underlies the web-site design. In particular, it is used in offline data access to applications can read e-mail, even despite the lack of connection to the Internet.

“When we do this are widely available, people come to this as the first mobile applications, HTML 5″, Gundotra said, refusing to say when it becomes available. “This will be as Gmail in 2004. It was a great moment for Ajax applications that use JavaScript for relatively sophisticated browser-based interfaces.

Mobile Gmail better use as a floating toolbar, which remained at the top of the Inbox, providing constant access to the archive and remove the buttons and menu options.

Mobile takes center stage in the work of Google. The company already provides a search application for iPhone and several other models, that allows people to issue requests to speak, rather than just text. The accuracy of speech recognition has improved 15 per cent last quarter, Gundotra said, and use of services is growing rapidly.

Gundotra previously worked at Microsoft, but it was a few words of his then 4-year-old daughter, which led him to Google. He would have told a friend he did not know the answer to a question, and his daughter, overhearing, asked him: “Dad, when your phone?”

“In his brief four years of life, it is assumed any time you do not know the answer to the question you brought from your phone. To your phone is the ultimate machine,” that responded to questions. This helped him to understand that Google is the mission of the world’s information and submit it to people, what will happen in mobile phones, too.

Google likes to HTML 5, but it takes time to become widely adopted. At the same time, other alternatives exist for rich Internet applications, in particular, Adobe Systems’ Flash. Also coming is a relative browserless Flash with Adobe AIR and Flash competitor called with Microsoft Silverlight is called.

Replying to a question about AIR, Gundotra said: “I think, Adobe has some great products,” noting, Google uses the power Flash video streaming on YouTube. “Ibid Silverlight from Microsoft. I am biased to the open Web standards,” said Gundotra.

And he even touted the HTML 5 Feature: “I predict we will see video tag has become widely accepted,” a technology that would allow streaming video without a Flash-player, similar to web browsers can display graphics, not requiring separate modules.

Gundotra also words of thanks for Google App Engine, and years of service, which can be used to run Web applications. One of the applications hosted on Google App Engine Moderators Google, which allows people to submit questions and rank what they want to hear the answers. Moderator arose as a way for employees to ask questions Google co-founders Larry Page and Sergey Brin at the weekly meeting of the employee, Gundotra said.

Google was excited, but scared, when the White House said that plans to use Google Moderator to the online town hall meeting with President Barack Obama, said Gundotra.

But he held under load, and 45,000 other applications (on Google App Engine) was completely independent of this scale is much, “said Gundotra.

Town Hall moderator system handled about 700 requests per second at its peak, with 3.6 million people voting on the questions they would like to hear the answers, “he said.
