    LAS VEGAS — The biggest gadget trade show in the Americas wrapped up on Friday in Las Vegas after swamping the city with 150,000 attendees. This year, ‘‘wearable’’ computing was big, along with various 3-D technologies, especially 3-D printing.

    Wearable devices in the shape of smartwatches and head-mounted displays have been a staple of the Consumer Electronics Show for a long time, but manufacturers were excited this year because the field is finally gaining traction with consumers. Fitness bands were a breakout hit last year. The 3-D printing section bustled with activity, and it was clear that even though most people won’t be buying a printer any time soon, they may be enjoying 3-D printed products, such as jewelry, wedding cakes and dental braces, in the near future. Meanwhile, TV makers were heartened by the support they received for their new ultra-high-definition TV sets.

    Here are some of the most notable products and services at the show:

    Driverless cars


    The state of the art in car electronics is in systems that eliminate or ease the task of driving. The French company Induct demonstrated its Navia driverless shuttle, which putts along at 12.5 miles per hour on a preprogrammed route. It’s intended for university campuses, airports, and other locales with enclosed roads.

    What about road safety? When a staffer walked slowly in front of the Navia, the vehicle slowed down, rather than coming to a full stop, because it recognized that the pedestrian ahead was moving, too.

    Then there was Audi’s automated parking demonstration. With a press of a button on a smartphone app, the German automaker’s computer-equipped car squeezed into a tight space between two other cars, a situation that would give many drivers pause. The car has multiple cameras and ultrasonic sensors, giving it a 360-degree view. It puts rubber-necking and looking through the side-view mirror to shame. The car executed a three-point turn flawlessly — and the driver didn’t have to worry about dinging other cars’ doors, because he had already exited the car.

    UV-sensing wristband

    The wearable computing trend has unleashed a lot of creativity. One example is a wristband with a ‘‘gemstone’’ that measures exposure to ultraviolet light, the kind that causes tanning and skin cancers. Using Bluetooth wireless technology, the Netatmo June sends readings to the owners’ smartphones, warning, for instance, when they’re approaching their daily limit of UV exposure. The battery lasts for six weeks.

    Netatmo, a French company, hopes to sell the device in the United States for $99, starting in the second quarter of this year.

    Ultra-high-def Netflix


    Netflix demonstrated 4K, or ultra-high-definition, video streaming. The company will offer relatively easy access to shows that take full advantage of the 4K TVs set to go on sale this year.

    (The 4K TVs on the market today don’t have the chips necessary to decode the picture.) Netflix’s 4K content will stream at 15.6 megabits per second, so viewers will need a relatively fast Internet connection.

    Enveloping photo booth

    At the Nikon exhibit, Los Angeles-based photographer Alexx Henry set up a small tent with 68 inward-facing, off-the-shelf Nikon cameras. When a subject steps inside the xxArray photo booth, an operator triggers the cameras simultaneously, yielding an image of the subject from all angles. Computers then process the images and create a 3-D rendition of the subject, which can then be posed in the computer as if it were an action figure.

    The 3-D model can also be imported into a game. So instead of playing with a generic game avatar, you may someday see yourself running around, blasting bad guys.

    Industry-watchers expect setups like xxArray to become more common and coupled to 3-D printers. In a few years, you might go to a photo studio and come home with a statue of yourself.

    Sugar printer


    A company called 3D Systems showed off ChefJet, the first restaurant-approved food printer. The device uses water to melt sugar into shapes as complicated as the mind can imagine. The company’s booth featured a wedding cake held up by an edible lattice-work tower that would have been nearly impossible to create by other means.

    ChefJet can print complex works in chocolate, too. Unfortunately, the samples the company handed out didn’t taste very good, but party planners and restaurateurs will probably be excited about the possibilities culinary 3-D printing opens up.

    Sony’s head-mounted display

    Sony’s head-mounted display looks like an enormous pair of glasses. When you strap it on, you take on the perspective of a motorcycle driver racing through the English countryside. Looking down shows the pavement speeding by; looking up shows the clouds. When you swivel your head right or left, you may feel like waving to the crowds along the road. All of this is enabled by a sensor attached to a strap that tracks your head movements and adjusts the wide-angle picture accordingly.

    Although there were a few kinks that marred the illusion, the demonstration gave a taste of what’s possible when wearable displays and computers combine with movement sensors.
