Microsoft's touch-screen Surface computers debuted in a Las Vegas casino bar on Wednesday, giving Sin City partiers high-tech tools for flirting and concocting cocktails.

Harrah's Entertainment Inc. became the second business, behind telecom giant AT&T, to deploy Microsoft's computer technology which essentially turns table tops into touch-controlled computer displays.

Harrah's said it put six customized Surface computers in a bar at its Rio All-Suite Hotel & Casino.

Harrah's crafted its own software for the machines and equipped them with cameras so people can send pick-lines, drinks or both to bar-goers they are interested in connecting with in real life.

"People continue to be excited about the endless possibilities of Surface technology and how it can transform everyday scenarios, including the social and entertainment space," said Microsoft Surface general manager Pete Thompson.

"We're now bringing some of those possibilities to life."

A "Flirt" feature in the Surface computers lets people exchange original messages or choose from suggested come-on lines.

Patrons can create drink recipes and then have the cocktails delivered to themselves or others.

People can use the computers to play games, watch online videos, or take a virtual stroll along the renowned Las Vegas strip without leaving their seat at the "iBar," according to Harrah's.

This is the first time Surface computers, which Microsoft sells for approximately 10,000 dollars each, have been put to use in an entertainment venue. AT&T uses Surface in some of its retail stores.

Harrah's vice president of innovation, gaming and technology Tim Stanley said investment in the technology is aimed at giving "a new genre of guests" chances to discover "uninhibited excitement."
