The International Consumer Electronics Show begins winding down, but USA Todaystill found plenty of interesting technology on the floor of the Las Vegas Convention Center.

Here's a look at what they discovered on Thursday.

Flip radio stations with a wave of the hand

Forget about fidgeting with car controls while sitting behind the wheel. Soon, it may be possible to open the sun roof, change stations on a radio or even adjust the air conditioning with basic hand gestures.

Mike Snider and Chris Woodyardtake a peek at the latest car technology, with manufacturers focused on gesture-based features.

Car makers such as Lexus are exploring infrared cameras inside steering columns that detect whether a driver is drowsy or distracted.

Is 3-D dead?

It sure seems that way, especially with television technologies such as 4K and OLED taking off.But as Ed Baig explains, there may be one way for 3-D to enjoy a rebound.

He takes a closer look at 3-D displays that don't require glasses, one of several hurdles seemingly keeping the TV sets out of most living rooms.

Several companies such as Dolby, Vizio and startup Stream TV Networks are showcasing displays that feature 3-D images minus the bulky glasses. So how does it look? Here's a quick take from Baig:

"You can't help but be impressed by the technology at work here, though I can't say I was blown away. There was plenty of pop in the 3-D demonstrations. But though I didn't do any side-by-side comparisons, I don't think the impact is quite the same as when you're wearing glasses."

It's not clear how much the sets will cost, but expect them to be pricey.

The perfect app for date night

Having trouble finding the ideal activity for a date? There's an app for that.

Influenced by his courtship of Becky Cruze, programmer Pius Uzamere created BeCouply, an app for Apple's iOS that helps couples find date ideas.

As Mike Snider explains, the app adjusts based on the time of day, so, for example, it will reccomend dinner options as evening approaches. Also, as the user's relationship blossoms, they can record every memory through a virtual scrapbook.

Although it's only on iOS, an Android version is in the works.

Nothing's worse than dropping a mobile device and watching that gorgeous screen shatter. Fortunately, Corning is going to make that tougher to accomplish with its latest version of Gorilla Glass. Watch what it can withstand.
