 While Tuesday at the Consumer Electronic Show was dominated by ultra-high definition TVs, smart refrigerators, and giant, tabletop screens, Wednesday seemed to be more about gadgets and innovative software to use on those fancy devices. Here's what made a splash on the second day of CES:

[GUIDE: What to Expect at CES 2013]

Time for bigger pockets
Chinese manufacturer Huawei debuted its Ascend Mate, which could be the largest smartphone yet, boasting a 6.1-inch screen, an 8-megapixel camera, and Dolby Surround Sound speakers. The device will also reportedly be water-resistant. The company is currently negotiating with American carriers to bring the phone stateside.

Fashion meets FaceTime
FaceCake showed off its 3D virtual dressing room, which uses a webcam to let users "try on" articles of clothing, new hairstyles, and shades of makeup.

Google checks its rear view mirror
Lexus premiered its version of the driverless car, although company officials wouldn't comment on when the car might be ready for consumers. "Our guess is not in the near future," Mark Templin, the company's general manager told the Los Angeles Times.

More space in less space
A decade ago, 32 megabyte flashdrives cost upwards of $100. Things sure have changed: Kingston introduced its DataTraveler HyperX Predator, a USB flash drive that boasts up to a 1 TB of storage—more than most consumer-level hard drives boast. The device will cost you, though: The 512GB edition costs nearly $2,000, and the company hasn't yet set a price for its 1 TB model.

Fuel cells finally ready for primetime
Nectar, a handheld fuel cell battery that can provide enough power to run a smartphone for two weeks, debuted Wednesday. The device will cost $299 and should be up for pre-sale from Brookstone in the coming weeks.

Crainium-controlled chopper
Puzzlebox introduced its brain-controlled helicopter. Users will wear a headset that monitors EEG waves—as long as the user is closely concentrating on one specific thing, the helicopter will remain afloat, its maker says. The device is available for purchase on Kickstarter for $189.

Samsung shows off
A familiar face showed up at Samsung's keynote address Wednesday: Former President Bill Clinton discussed how technology could help solve some of the world's problems and even took time to urge politicians to reinstate the assault weapons ban he signed into office.

"I grew up in this hunting culture, but this is nuts," he said. "Why does anyone need a 30-round clips for a gun?"

Besides Clinton, Samsung had some other surprises: It introduced what it's calling the Exynos 5 Octa chip, a smartphone microprocessor that boasts eight cores and has been touted as the fastest cellphone processor ever.

Make room for more games
Nvidia also unveiled a new processor, the Tegra 4, which wowed plenty of people at the show. But it also announced its plans to get into mobile gaming with Project Shield, a handheld gaming device that looks like an Xbox controller connected to an Android phone. Pundits at the show seemed to pan the device—established gaming companies such as Sony and Nintendo had rough launches with the Vita and 3DS, respectively. While the 3DS seems to have found its footing of late, the Vita continues to sell poorly. With Shield expected to play only Android games, it may not have the support to get people to switch away from using their smartphones.
