Last week's Consumer Electronics Show was a great opportunity to check out the two newest TV technologies, Ultra HD and OLED—sometimes in side-by-side comparisons. During a live webcast in which I was interviewed along with USA Today's Mike Snider, we were asked which of these new kinds of TVs we'd personally buy, if money weren't an issue.

Personal devices that monitor your activity and vital signs and upload that information to your computer or mobile device were the hot health technology at this year's CES. At the show's Digital Health Zone, I saw a gaggle of new gadgets that track your body in multiple ways, even during sleep, and integrate that data into a comprehensive report on your overall wellness.

There was a lot of cool stuff on display at CES. In fact, there was a lot of stuff, period. Trying to find a single standout isn't easy, especially when it is near-impossible to even see everything at the massive event. But there were a number of products and technologies that did get us excited.

Lots of cameras and camcorders were introduced at CES 2013. Here are a few of the most intriguing offerings I encountered, which may well change the way you shoot photos and videos in the coming months or years:

Car shoppers these days may not look much beyond the stereo. They come into the showroom and see if their phone will connect, then sign on the dotted line. And while we've been seeing some good cars from Subaru lately, their lack of modern connectivity systems is an overt shortcoming. Until now.

If rooms were round, the robotic vacuums tested in the past by Consumer Reports would have been better at tidying up. But in our tests, they tended to miss edges and corners. Now LG has introduced the LG Hom-Bot Square at the Consumer Electronics Show. It claims the vacuum has "newly designed corner master technology" and can now get into hard-to-reach places.

Just as next-generation televisions are gaining resolution, TomTom is adding detail to its traffic service for car navigation.

If you're thinking you have to run out and buy a new car to get all the latest safety features like lane departure and forward collision warnings, automatic high beam control, and even a speed limit warning, think again.

Inrix, the company behind the traffic information appearing on many built-in and portable automotive navigation systems, announced at CES that they're adding parking information to their services.

Part of the fun of CES is seeing the cool new products coming to the market soon, but the mondo electronics trade show is also big on pulling out all the stops to give attendees a peek into the future, or at least what various manufacturers think the future might look like.

Cleaning the oven is such a detested chore that some cooks admit to running the cleaning cycle of their range or wall oven only once during its lifetime. For almost as long, appliance makers have been looking for an easier way. LG took the plunge this week when it introduced a new series of self-cleaning, large-capacity ovens with a new coating called Aqua Clean Enamel at the Consumer Electronics Show.

If you haven't heard of Aha radio, get used to hearing the name, especially if you're in the market for a new car.

At CES this year, most camera makers are unveiling new rugged and/or waterproof models—but Olympus has been among the most aggressive, by offering no less than three of these cameras.

To date, many so-called 3D printers that make three-dimensional objects layer-by-layer have costs tens of thousands of dollars and been too complicated for most consumers to use. But the Cube 3D Printer on display at this year's Consumer Electronics Show aims at relative simplicity and affordability at $1,299—and is a modest success on both counts, I think.

Audio may not be getting as much attention as other electronics categories, but there are a couple of intriguing trends on view at CES this year, in headphones and in wireless audio systems.
