The 2013 Mobile World Congress is just a day away from closing in Barcelona, Spain. Housed in a brand-new venue and bigger than ever, the show burst at the seams with everything wireless. Sure, there were a ton of new phones and tablets, but those headline devices only scratched the surface. CNET's team of reporters scoured the show floor to find everything from a GPS-enabled cane to a touchless touch screen.

So if you can't be in Barcelona, join CNET for a video tour of some of the hottest devices and most fascinating finds of the show.

1. A touchless touch screen

New technology from chipmaker STMicroelectronics lets you control your smartphone or tablet without actually touching the display.

2. Fujitsu New Generation GPS Cane

We go hands-on with the Fujitsu New Generation Cane, a prototype walking stick for the 21st century that guides you by GPS, tracks your heart rate, and lets loved ones know where you are.

3. NEC Medias W N-05E

NEC's Medias W N-05E smartphone has two 4.3-inch qHD displays screens, which you can fold out to make it a 5.6-inch tablet of sorts. It's unique, to be sure, but the whole thing just seems awkward.

4. Artificial Solution's Indigo app

Personal assistant Indigo brings the functionality of Siri to Android, Windows Phone 8, and your Web browser. Better yet, it's free and isn't ad-supported.

5. Qualcomm's Wi-Fi coffee machine

The Qualcomm-modified device can be controlled using a tablet, and it notifies you when your brew is ready to imbibe. I want!

6. Asus FonePad

The 7-inch Asus FonePad delivers Android Jelly Bean, it runs on an 1.2GHz Atom Z2420 processor, and it lets you take calls -- if you don't mind a phone the size of your head.

7. Nokia Lumia 720

The Nokia Lumia 720 has the familiar Lumia unibody design, a microSD card, support for wireless charging, 8GB of internal memory, and a 6.7-megapixel camera with an f/1.9 aperture and an LED flash.

8. Samsung Galaxy Note 8

The Galaxy Note 8 is the smaller followup to the Note 10.1, or possibly the larger sequel to the Galaxy Note 2. Either way, it's no doubt an intriguing piece of kit.

9. LG's 4K phone

The new upscaling system outputs a 4K feed to your TV, letting you play games or watch films at an eye-watering resolution, from your phone.

10. Nvidia Tegra 4

Nvidia's latest Tegra 4 and Tegra 4i processors aim to boost gaming performance and battery life.

11. DryWired waterproofing technology

New nanotechnology from DryWired promises to seal up phones and tablets, guarding them from liquid harm.
