Nearly 3,200 exhibitors showed off their latest products and services in Las Vegas to an audience of about 150,000 attendees at the Consumer Electronics Show, which is the world’s largest annual consumer technology trade show.
The new products range from speakers and wearable fitness trackers to advancements in television and mobile technologies.
Take a look at some of the products and deals that were unveiled at the trade show.

Sony EXPERIA Z1 Compact
Sony unveiled a waterproof smartphone that sports a 21 megapixel camera and expands what users can do with it underwater.
Sony Corp. said the new Xperia Z1s can be submerged as much as 4.5 feet deep for up to 30 minutes, compared with just 3 feet for last summer’s Xperia Z. The Z was water resistant rather than waterproof.
Kunimasa Suzuki, executive vice president of Sony Corporation and president and chief executive officer of Sony Mobile Communications, showed the new phone.
Huawei, China’s largest cellphone manufacturer, unveiled a phone that is so large, it can be thought of as the inflight refueling system of the mobile world. The Ascend Mate2 has enough power to recharge other phones.
It has a 6.1-inch screen, making it more than twice as big as an iPhone 5. It’s also almost the size of a tablet, giving rise to the half-joking term ‘‘phablet.’’
The FLIR ONE thermal imager attaches to the back of an iPhone 5 or 5s and translates heat data into color images on the phone’s screen. For instance, you can set it to show hotter things in yellow, medium-hot in red, and cold in purple.
The FLIR One will cost $349, which compares with $995 and up for FLIR’s professional thermal imagers.
The FLIR One will launch this spring for the iPhone 5 and 5S. It won’t work with the 5C. An Android model will be available later this year.
LG Electronics announced that it is bringing its smartphone with a curved six-inch screen to the United States later this year. LG has deals with wireless carriers AT&T, Sprint, and T-Mobile US to deliver the service to US consumers.
The device is being touted as the first step in the smartphone’s evolution from a rectangle that doesn’t bend into a device that someday will be able to roll up like a scroll or fold like a wallet.
Besides a concave screen, the G Flex’s other distinguishing features are a curved battery and a special coating designed to automatically repair minor scratches to the exterior.
This new iPhone case backed by Ryan Seacrest gives your iPhone a Blackberry keyboard.
Its similarities with BlackBerry phones are notable: It has angle-cut keys suitable for thumb-typing. The keyboard layout is nearly identical — for example, with parentheses above the ‘‘T’’ and ‘‘Y’’ instead of the ‘‘9’’ and ‘‘0’’ on a typical keyboard. Thick silver bars separate rows of keys.
Physically, there are a few differences. Because the Typo case covers the iPhone’s home button, it added one with the same function on the bottom right. There’s a Bluetooth function on the ‘‘0’’ key so the Typo can connect to the iPhone wirelessly. A light bulb key on the bottom left gives Typo’s keys some lighting to use in dark environments.
BlackBerry is suing Typo Products LLC over the device, accusing it of copying its world-famous keyboard.
AT&T to sell toll-free service for wireless data
Websites that pay for the service will be toll-free for AT&T’s wireless customers, meaning the traffic won’t count against a surfer’s monthly allotment of data.
AT&T is the first major cellphone company to create a comprehensive service for sponsored wireless access in the United States.
One of the first customers of the service is Aquto, which has an app that rewards users with extra data if they watch ads or download specific apps.
Health insurance company UnitedHealth Group will also use the service when it launches in the first quarter.
The service is likely to face considerable opposition from public-interest groups that fear the service could discourage consumers from exploring new sites that can’t afford to pay communications carriers for traffic.

Toshiba Ultra HD 4k TVs
Ultra HD is the first TV format to be driven by the Internet video-streaming phenomenon pioneered by companies like Netflix and Amazon.
Toshiba makes the cheapest name-brand manufacturer’s model — a 58-inch screen that sells for $2,750.
Smart TV software from LG
LG announced plans to power 70 percent of its smart TVs this year with the webOS mobile system it bought from Hewlett-Packard last March. Although LG hasn’t disclosed specifics, the use of webOS paves the way for owners of LG sets to control home appliances from the TV. For starters, LG said the new software will make its TVs easier to set up and use.
Quattron + technology from Sharp
Sharp is bridging the gap between expensive 4K TVs and HD versions with an in-between solution that is also priced in the middle.
Its new Quattron+ technology doubles the vertical resolution of a high-definition set by chopping the existing pixels in half. Meanwhile, it uses a mathematical formula to double the horizontal resolution for everything but certain parts of an image.
The company says that its Quattron+ televisions have 16 million subpixels, versus 8 million for its Quattron line and 6 million for HD. Ultra HD televisions have 24 million subpixels.
A 70-inch model is expected to retail for about $3,200, far less than a similar 4K model that will retail for about $5,500.
Sony, Netflix partner
Netflix CEO Reed Hastings showed up at Sony’s news conference to say the streaming company was working to deliver UHD video to Sony’s Bravia line of 4K sets.
Hastings said UHD signals could be streamed if one has download speeds of at least 15 Megabits per second, a speed that is readily available to average households. He said streaming would even work over a Wi-Fi connection.
Pictured is Sony’s new 65-inch 4K LED TV.
Roku TV to stream without set-top box
While similar to smart TVs that are already on the market, Roku’s streaming platform will offer some 1,200 apps and more comprehensive niche choices.
The company is partnering with two of the biggest Chinese TV makers in the world, TCL Corp. and Hisense International Co. Ltd., on six models.
The Roku TV will also provide users a way to access feeds from regular live TV providers and to connect to other devices such as Blu-ray disc players.
Samsung, Comcast partner for ultra-HD movies
Samsung said it is teaming up with the Internet streaming services of Comcast, Netflix, and Amazon to deliver ultra-high-definition content to its new TV sets.
Under its partnership with Comcast Corp., the country’s largest cable company, Samsung TVs would get UHD content through an app running on the Internet-connected TV, bypassing Comcast’s set-top boxes.
Comcast owns NBCUniversal, the movie studio and creator of TV shows, giving it direct access to content shot in UHD, which is also known as 4K.

Dish Super Joey
The Super Joey, a companion box for Dish Network’s Hopper set-top box, features two tuners enabling users to record up to eight shows at once.
The catch is that four of those shows have to be from the broadcast networks ABC, NBC, CBS and Fox.
For a $12 monthly fee, TV subscribers can rent Dish’s Hopper, which can send all of a subscriber’s live and recorded shows to mobile phones and tablets. Joey box rentals for separate TVs cost up to $7 a month.
Netflix app to stream 4K on new TVs
Netflix showed off streaming in Ultra HD, or 4K, on the sidelines of the International CES gadget show. The format has four times as many pixels as standard HD and vastly improves the clarity of larger screens that measure 60 or more inches diagonally. Netflix videos that are available in the sharper format are labeled with the ‘‘Ultra HD 4K’’ symbol.
The video streaming of its programming in ultra-high definition will work for buyers of new UHD sets from Sony, LG, Samsung, Vizio, and others upon purchase.

Amazon, CBS agree on exclusivity for ‘Extant’
Amazon will have exclusive ad-free streaming rights in the US to the CBS thriller starring Halle Berry.
Episodes will be available for free on CBS.com and CBS’ app with ads the day after they air on CBS. Members of Amazon’s $79-a-year Prime service will be able to watch ‘‘Extant’’ ad-free four days after broadcast. Non-Prime members can buy episodes, but only through Amazon.
LG gets into the wearable fitness market
The company is making earbuds that will measure your heart rate from inside your ears. The earbuds connect to a small medallion that syncs to a smartphone via Bluetooth wireless technology.
It is also making a wristband that sports an organic light-emitting diode display that allows the user to control music, accept incoming calls, and be alerted to text messages.
The Nabu made by Razer is a wristband that acts like a fitness tracker but also serves up notifications, texts, and e-mails like a smartwatch.
The Nabu extends battery life because it can recognize gestures. It can notify you of texts or e-mails with a small indicator on the top of the wristband, but it won’t display the text unless you turn over your wrist.
The Nabu also senses other Nabu bands nearby — making it a location-based social tool — and connects wirelessly to your smartphone or Wi-Fi network.
The company is developing the Nabu as an open platform so that outside software developers can write apps for them. Razer is selling the Nabu to developers for $49 starting immediately. It plans to sell it more broadly by the end of March, likely at a higher price.
Pressure sensor insole
Boogio co-founder and CEO Jose Torres wore the Boogio pressure sensor insole at the 2014 International CES.
Boogio is a wearable insole with pressure sensors and accelerometers for each foot to capture body mechanics with a high degree of accuracy. Boogio can log activity, analyze movement, and send the information to a smartphone or tablet via Bluetooth.
Sensoria Fitness bra
This device by Heapsylon eliminates the need for heart rate monitoring straps. It is equipped with textile elextrodes that monitor your heart rate.
It costs $89 and is available for pre-order.
This waterproof wristband tracks everything from daily physical activities and nightly sleep patterns to how much you’ve socialized with friends.
The sensor-packed band has no display and interacts wirelessly with an Android smartphone or tablet through an app called Lifelog. It keeps a daily record of activities and recommends actions for the future.
SmartBand also informs its wearer of incoming calls and messages by vibrating. Users listening to music can use it to play, pause or skip tracks.
The company said it would be available in the spring.
EGO LS wearable camera
Liquid Image created an 8-megapixel camera that is WiFi enabled and has Bluetooth for remote control use and audio capability. It can be used with a module with 4G LTE so the user can live stream video anywhere.
The camera will be available in June $199 and the module will be sold separately, also for $199.
Autographer wearable camera
The 3.5-inch tall camera weighs only two ounces and has five built-in sensors that intelligently decide when to automatically take photos. It can clip onto clothing or be worn on a lanyard.
It has a 136 degree eye-view lens which simulates the human field of vision and 8GB built-in storage.
4K wearable TV camera
This product from Panasonic is a portable camera that hooks onto your ear and records in ultra-high definition 4K video.
The device is waterproof, dust-proof and designed for the everyday person, Panasonic said.
This hydrogen fuel cell vehicle will go on sale next year in the US. It has a battery that uses hydrogen stored in a 5-kilogram (11-pound) tank and oxygen that rushes in through the front grill.
The electric engine vehicle can get 300 miles while only emitting water and water vapor.
Ford C-MAX Solar Energi
This is a prototype for a solar hybrid car. The car has a gas engine along with rooftop solar panels that also power the engine. It is designed to park under a 15-foot-tall carport made of a thin magnifying glass called a Fresnel lens that concentrates the sun’s rays onto the panel to efficiently generate electricity. The carport isn’t portable. So the car has to stop and recharge.
Seven hours of sunlight gives a full charge — the average amount of light in a typical American city, according to Michael Tinskey, Ford’s associate director of vehicle electrification and infrastructure.
The vehicle must park facing east-west and inch forward to make the most of the sun’s rays as it passes overhead. With the movement, it’ll get a full charge, enough to run 21 miles on electricity only. Without the movement, it’ll get only 3 miles of juice on a seven-hour charge, before the gas engine needs to kick in.
Valeo self-parking technology
Take the pain out of finding parking.
Valeo’s self-parking technology uses sensors and cameras to “look’’ for a free parking spot.
The driverless parking is initiated with an iPhone app. The Range Rover Evoque pictured here is equipped with 12 ultrasonic sensors, six in back and six in front, a laser scanner mounted in the grille, and four cameras.
The smart toothbrush by Kolibree uses an accelerometer, gyroscope, and magnetometer to track how well users brush their teeth. The French company expects the toothbrush will be available in the third quarter of 2014 and retail for $99.00 to $199.00 depending on the model.
SmartOne infant sleep monitor
The wearable device fits into a chest pocket and sends information and active alerts on temperature, baby orientation, and breathing to a parent’s mobile device. The device will retail for $149.00 and be available online in the second quarter of 2014.
This table will nudge you to stand, with a gentle, one-inch rise and fall of its surface. If you take the suggestion, the table rises to standing height.
The table is controlled from a color touch screen. It looks as though someone has hammered an iPhone into the table’s surface. To change between sitting and standing positions, you tap it twice. You can program it to make you stand, say, 35 percent of the time. A hidden heat sensor helps the desk determine whether you’re there.
The screen also controls the table’s Bluetooth and Wi-Fi connections. They don’t do much right now, but the plan is for the table to connect to your smartphone to track your sitting and standing periods.
One day, it’ll also connect fitness bands such as the Fitbit to help the table figure out when you should be sitting and standing.
The desk also contains power and USB connections in recessed, lidded boxes, so you can charge your phone straight from the desk, then hide the cable under a lid.
You can order the desk for $3,890, which is about three times the price of a simple motorized adjustable-height desk. Stir expects to start shipping the tables in February.
iPhone car game
Toy race-car company Anki has made an iPhone-controlled car game. The toy cars race on a plastic track that can roll up and go anywhere.
The iPhone app, which also works on iPads and iPod Touches, controls the cars. There are two main buttons: a throttle that swipes up or down, and a weapon button that drivers tap to shoot straight ahead. Enough hits will disable the vehicle in front of yours, allowing you to take the lead.
Rotating the iPhone left or right steers the car, though it can’t leave the painted-on borders of the track. Keeping the device straight keeps the car going round and round the track in roughly the same lane.
A starter kit costs $200 and comes with two cars. Each extra car costs $70. An iPhone is not included.
This virtual-reality headset from Sony almost puts you inside a video by allowing you to widen your view when you turn your head up, down or side to side.
A hooded viewer contains two screens measuring 0.7 inches diagonally. Each screen delivers high-definition images in 720p resolution to each eye. Little slider knobs under each screen help you focus.
The product costs $1,000.
The hands-free computer by Kopin was designed for a firefighting application and can stream both regular video and infra-red cameras.
The speaker, produced by ClearView Audio of Waltham, uses a single piece of curved millimeter-thick acrylic glass that sits on a dock which vibrates it in a finely tuned way so that it can play music. It works with Bluetooth streaming and with a 3.5 millimeter jack.
The product will retail for $349 and is expected to ship in late March.
MakerBot’s Replicator Z18
This 3-D printer is the largest model made by the company to date. It can print objects 12 by 12 by 18 inches large, which is six times larger than MakerBot’s standard Replicator. The machine, which deposits melted plastic dot by tiny dot, will cost about $6,500.
Nvidia unveils a new chip for tablets, smartphones
Nvidia, which makes chips for PCs and smartphones, announced a new chip called the Tegra K1. The chip is meant to be used for smartphones and tablets and contains 192 computing “cores,’’ or mini computers, for graphics applications.
The company used a publicity stunt to promote the chip.
It created a crop circle near Chualar, Calif., containing a stylized image of a computer chip and the number 192 in Braille.
