"This year's show was all about connectivity — both in the form of the technologies unveiled and in the valuable face-to-face business connections happening throughout the show," said Karen Chupka, senior vice president, CES and corporate business strategy, CTA.

Here are a few highlights:

Toyota’s Concept-i car. Sleek and futuristic, it drives and parks itself and also comes with a built-in virtual assistant Yui who senses driver’s emotions and adjusts the settings. No research was offered on the consequences of getting too emotionally involved with your car.

LG "wallpaper" TV. It truly does look as thin as wallpaper and it’s 4K. The brand’s W7 65- and 77-inch super thin TVs attach straight to the wall. Plus, LG claims their picture quality is better than last year's, which are pretty terrific.

Under Armour Gemini smart shoe. This sneaker is committed to your fitness even more than you are. It tracks and stores data about your workouts and syncs it with an app for real-time performance measurements. And it will tell you, via the app, how far it thinks you can go today based on six jumps in a row.

Lego Boost motors and smart bricks. Ever built a Lego robot and wished it could be real? Now it is! The Danish toymaker brought a set of motors and programmable bricks that work with existing Lego sets and turns them into a motorized or motion sensitive toy. The companion app records voice effects to really bring your creation to life.

Sleep Number 360 smart bed. If your cat doesn’t keep your toes warm at night, this new bed will turn on the heat. No more cold feet! It will also compensate for changes in position to reduce the volume of snoring.
