Whether it's a doorbell or refrigerator, a TV set or a toothbrush, chances are it will be connected to digital assistants powered by artificial intelligence aiming to anticipate needs or desires.
"I think you're going to see the year of smart," said Jack Gold, a technology analyst with J. Gold Associates.
"I think you are going to be overwhelmed by smart homes and voice -- the voice speakers yelling at you in the convention center and up and down the (Las Vegas) Strip will be overwhelming," Baker said of CES.
"To some degree there is still a war on for the connected home platform," Blau said.
"Communication standards are being worked out, but the other thing is whose allegiance you will commit your home to -- will it be Samsung, LG, Amazon, Google?"
"I definitely see the speaker still be key to controlling the connected home," she said.
CES hosts the debut of a $130,000 electric car from Fisker -- a relaunched startup led by former BMW designed Henrik Fisker whose previous venture went bankrupt -- and one of several challengers to rapidly expanding Tesla.
Although CES ends just days ahead of a major Detroit auto show, O'Donnell said automakers are eager to show their new technology to a wider public.
"It's a place to make a statement about technologies that will have resonance," he said.
"And the vast majority of the new innovations in cars are in fact tech things."
Keynote speakers include Ford Motor Co. chief executive Jim Hackett, Intel's Brian Krzanich and Huawei consumer chief Richard Yu.
