Hot new gadgets and gizmos from the IFA innovation show

Nearly 1,400 of the world's leading technology companies have descended on the International Congress Center in Berlin for the 2013 IFA (Internationale Funkausstellung Berlin) Trade Fair.

The annual show is a chance for leading consumer electronics and home appliances firms to show off their latest wares. But there's also a chance for new kids on the block to try to bring novel gadgets and ideas to the market. The main focus is on digital products, from ultrahigh definition displays to smart televisions, tablet computers, smartphones and networked home appliances.

With 80 different rooms and space for nearly 10,000 people, the show could be described as gadget heaven—even if it does require some heavy walking!

Samsung has made the biggest noise at the show so far, with the release of its Galaxy Gear smartwatch, marking the first entry by a major tech company into wearable technology.

However, there's much more on display at the show. CNBC highlights the major products that are drawing the crowds at this year's event.

After months of anticipation, Samsung introduced Galaxy Gear at IFA.

The smartwatch is connected to a Galaxy user's smartphone and shows a user's updates, like email or texts, on the screen. It also has built-in sensors that can track a user's physical activity. It can make and receive calls, take pictures and run its own apps, and it has a voice control function that allows users to perform tasks by speaking to the device.

But Macquarie analyst Daniel Kim said the device was an "expensive accessory" with a limited target market given its $299 price tag.

With a super-sleek body, the Vibe is now the Chinese firm's flagship smartphone. Packed with the Android 4.2 Jelly Bean operating system, it weighs just 121 grams and has a depth of 6.9 millimeters.

Despite the phone's dainty appearance, Lenovo said it will have a 1.5-gigahertz quadcore processor and a 5-inch full-high definition screen.

Keen to buy? A China release is scheduled for November, but there's no price yet. And European and U.S. fans will have to wait a little longer to get their hands on the device.

Best known for making processing chips, Qualcomm branched out by launching a smartwatch at IFA.

Like the Galaxy Gear, the Qualcomm Toq works in conjunction with a user's smartphone to display alerts. For now it only can be used only with Android devices, but Qualcomm may extend the connectivity to work with Apple's iOS.

Available for pre-order immediately, the Toq is priced at $300 and is scheduled to hit stores Oct. 10.

Daniel Matte, a technology analyst at Canalys, contrasted the Toq with the Galaxy Gear.

"Its claims of four- to five-day battery life are quite credible, and it does interact with a much larger base of Android devices. While the device is more focused than the Gear, it is much simpler in functionality," he told CNBC.

Matte added that the Toq was "largely a marketing exercise" to sell Qualcomm's Mirasol display technology to smartwatch vendors.

If you think "phablets" are fab, then Samsung might just have the product for you: the Galaxy Note 3.

With a 5.7-inch screen, the cross between a phone and a tablet may prove a little tricky to fit into your pocket, but its multiwindow display allows users to easily complete different tasks.

Though the Note 3 is larger than previous models, Samsung says it is also lighter, slimmer, faster and longer-lasting. It is due for release Sept. 25.

The Korean tech giant told a packed audience in Berlin that the phablet was the perfect accompaniment to its Galaxy Gear smartwatch. No price has been confirmed yet, but buying the pair together is expected to cost about $1,000. Better start saving those pennies.

Perhaps in an attempt to upstage its Korean rival, Sony held its press event two hours ahead of Samsung's Galaxy launch. After a glitzy entrance, Sony CEO Kazuo Hirai spoke of the "rapid change" the company had made before unveiling its flagship smartphone, the Sony Xperia Z1.

The waterproof device features a 20.7-megapixel, rear-facing camera with a 5-inch display.

"It's a challenging market, but we have a winning product," Hirai said. "[What] we've packed into Xperia Z1 is something that's really going to wow customers around the world."

Very much a buzz term at IFA 2013, "4K" resolution allows for ultrahigh definition television and cinema with four times as many pixels as normal high definition.

Panasonic revealed its first foray into 4K at the show: a television with a whopping 65-inch screen and a price tag to match, at $5,999.

The 65WT600 is the first TV to comply with the HDMI 2.0 interface. Panasonic hopes that like other audio-visual equipment before it, such as Scart cables and the original HDMI, this television will become the industry standard.

The release is scheduled for October.

Not satisfied with a smartwatch and a phablet, Samsung added a 2014 edition of its Galaxy Note 10.1 to its arsenal at IFA.

The upgraded tablet is slimmer than its predecessor and is ready to take on the likes of the Apple iPad. It can be classed as a big brother to the Galaxy Note 3.

The Note 10.1 features multiwindow, Android Jelly Bean 4.3 and the brand's trademark S Pen, which is now smaller and stored horizontally. The new tablet is available in Europe on Sept. 25, with a global rollout expected next month.

The price hasn't been confirmed.

After a brief hiatus, LG is back with a tablet whose 8.3-inch screen means it's in the iPad's league. LG says it's the only 8-inch device of its kind to feature a full high-definition display. It will retail at $499.

The company also gave its new Android smartphone its first European outing at IFA. The LG G2 has just one button (a volume control on the back), and LG says it's the ideal companion to the G Pad 8.3.

Both the tablet and the smartphone will be available worldwide in the fourth quarter. The pair will be available before Christmas in a bundle, if you're feeling generous.

Despite a flood of research showing that growth in e-reader take-up might have reached its peak, Amazon has once again added to its family of Kindles.

The sixth edition of the Paperwhite was released at the IFA and Amazon said the new device has improved back-lighting, higher contrast and several improved software features.

Now available from the online store, it's priced at £109 ($170) for the Wi-Fi version and £169 ($264) for the 3G version.

"No one is investing on behalf of readers or pushing the boundaries of hardware, software and content for readers like this team," CEO Jeff Bezos said in a press release.

But Amazon has got competition. Its rival Kobo showed off the new Aura 6-inch e-reader at the same event along, with three Google-certified Kobo tablets.

Has driving just turned into a computer game? Much more than a sat nav, this device from Pioneer uses augmented reality to create what looks to the driver like a 30-inch display, sitting about 3 meters in front of the vehicle.

Priced at £600 ($938), it's set to go on sale in October. Hooking up to a smartphone with the navigation software, the driver can look into a sun visor which then projects traffic, navigation and other information in full color through the windscreen.

Never take your eyes off the road again.

This is the world's largest ultrahigh definition OLED (organic light-emitting diode) TV, according to South Korean tech giant LG. Ultrahigh definition contains around four times as many pixels as full high definition.

There are no details on a release date or pricing, but rest assured that you might have to pay megabucks.

"This 77-inch TV is proof that we will never stop pushing the boundaries and exploring new possibilities," said Havis Kwon, president and CEO of LG Home Entertainment, in a press release.

Now all you need to find is a room big enough to fit it in.
