WATCH CES in 60: Audi Piloted Parking

We came, we saw, we survived. We spent the past week scouring CES 2013, one of the largest consumer electronics shows in the world. With more than 1.9 million net square feet of show floor space and 33,000 exhibitors, it's impossible to see everything at the event, but we did see some pretty incredible, innovative and downright crazy products.

Here are some of the best things we saw this week.

1. Audi's Car Parks Itself
If there's one thing that blew our collective mind this week it was Audi's piloted parking demo. We've seen the autonomous driving demos before, but Audi showed off how to tap a button on your iPhone, have the car start, drive itself out of the garage and pick you up. Then you can get out of the car and tell it to park itself right back where it came from. Pretty futuristic stuff, but while Audi can legally test the autonomous cars in Nevada, the future is about a decade away for everyone else, Audi told us.


2. Ultra HD or 4K TVs
They aren't self-driving cars but Samsung, Sony, Toshiba, Vizio and more dazzled with their new 4K or Ultra HD TVs. The TVs all have four times the resolution of current 1080p TVs, which means the picture looks incredibly crisp and vivid. In particular, Samsung's S9 TV, which sits in a frame that looks like an easel, impressed us. The company displayed 85- and 110-inch models, and the content on the screen was jaw-dropping. Samsung's version will be out in the spring, but no word on the pricing.

3. Eye Tracking
Sometimes a mouse or a touchscreen just isn't enough. A company named Tobii showed off how it could use your eye as a mouse. Look at an area on a map and use the scroll wheel, and it will zoom right in on where you want -- not some place far off east or west. Look down, and you can scroll when you are done reading. It's not the first time eye tracking has been shown, but it is one of the first times the demonstrations have worked so well. Tobii will start selling its Rex computer accessory to software developers soon and hopes to bring out a consumer version before the end of the year.

4. Fitness and Health Gadgets
From a fork that vibrates when you are eating too fast to a number of brand-new devices that track your activity, fitness and health-oriented gadgets were one of the biggest things we saw at the show. FitBit's Flex is a stylish wristband that tracks your steps taken, calories burned and hours slept, and then syncs them with your phone, while the $99 HapiFork pairs with your phone to tell you about your eating speed and meals. And yes, it vibrates when you eat too fast.

5. The Oddities
Mind-controlled cat ears. Snooki's Couture headphones with built-in earrings and her bling-bling shoe landline phone. And a potty with a built-in iPad holder. Do we need to say more?
