It opened on Tuesday and is one of the world's biggest trade fairs devoted to technology, with some 36,000 exhibitors and about 160,000 visitors.
A more personal or "me" approach to technology is one of the major themes at the show, connecting thousands of objects that people use each day - clothing, cars, light bulbs and home appliances.
Some of the new devices on display include a baby bottle to measure infant nutrition intake, floating speakers and shoes with wheels that help you walk faster, AFP reported.
Mr Shawn DuBravac, chief economist at the Consumer Electronics Association, said: "The key to all of this is that something happens in the physical space and we digitise it and feed it back into the physical space.
"No longer is the focus on what can technologically be done but what is technologically meaningful."
These new technologies "continue the trend of deploying the Internet in a personal way", Mr DuBravac added.
The fair ends today.
So you want to...
1 WALK FASTER
Rollkers is a transport accessory that can increase a person's average walking speed to 11kmh. Rollkers fit to the bottom of shoes and can be adjusted to fit any size or shape of shoes. Rather than actually rolling on them, you walk normally with them.
2 TIGHTEN YOUR BELT
Belty monitors the wearer's waistline measurements and advises when it is time to lose weight. Belty automatically loosens when the wearer sits and tightens when the wearer stands. The product is still under development, but its creator expects to have it on the market by the fourth quarter of the year.
