The Consumer Electronics Show officially kicks off Tuesday, after a jam-packed day of product announcements for the media on Monday. After a day of new ultrabooks, televisions and smartphones, Microsoft chief executive Steve Ballmer gave his final CES preshow keynote. The speech came with no major announcements but highlighted the release of the Windows Phone-based Nokia Lumia 900, HTC Titan II and Nokia Lumia 710 as well as the announcement of an XBox content partnership.

The main events Tuesday will be anchored by three keynote speeches. The first is from Qualcomm chief executive Paul Jacobs and Consumer Electronics Association President Gary Shapiro. They will discuss the state of the consumer electronics industry and the Technology and Evolving Countries (TEC) program, which highlights the role technology plays in countries around the world.

A few hours later, Dieter Zetsche, chairman of the Board of Management of Daimler AG and head of Mercedes-Benz, will speak, marking the first time that the automaker has been at the show. Mercedes-Benz has already been showing off its mbrace 2 software, a communications platform with cloud-based apps, traffic assistance, speech recognition, Internet search and more.

Rounding out Tuesday’s keynotes, Intel’s Paul Otellini will take the stage, probably pushing more of the company’s ultrabooks. On Monday, Intel’s Mooly Eden hinted that Otellini would make more announcements about the fast, slim and powerful laptops that are the main trend of this year’s show.
