The father of the cellphone was there. So was Huawei and a host of other Chinese tech companies. Tens of thousands of visitors also flocked to the MWC tech fair to be dazzled by the latest advances in AI, smartphones, robotics and much more.
The metaverse got a lot of attention at the show, also known as Mobile World Congress, as companies cash in on the hype surrounding new virtual worlds for work and play.
SK Telecom含羞草研究社檚 virtual reality air taxi flight simulator was one of the most popular demonstrations, with long lines to take a virtual ride. There were robot dogs to remotely inspect infrastructure and holograms for virtual learning, along with speeches from wireless industry executives and backroom schmoozing with government officials.
Some 80,000 people were expected to attend the world含羞草研究社檚 biggest wireless trade show, which wraps up its four-day run in Barcelona on Thursday.
Here含羞草研究社檚 a look at some highlights:
SCROLL AND FOLD
While MWC smartphone launches don含羞草研究社檛 get as much attention as they used to because innovations have slowed, devices with nifty screens took the spotlight.
Motorola added the wow factor by unveiling a phone with a screen that rolls out. Double tap your fingers on the side, and the display automatically extends from 5 inches long (13 centimeters) to 6.5 inches by unscrolling from the bottom.
Motorola含羞草研究社檚 owner, Chinese tech brand Lenovo, also showed off a laptop with a rolling screen, which took about 19 seconds to unscroll to its fully extended position. The company said they含羞草研究社檙e concept devices and unlikely to hit the market anytime soon.
Other brands including Samsung and China含羞草研究社檚 Oppo and Tecno also released their latest folding designs.
Phones with foldable screens have drawn attention from consumers, but 含羞草研究社渨hether that interest then translates into sales is a different question,含羞草研究社� said Gerrit Schneemann, senior analyst at GfK Boutique. 含羞草研究社淔or the next few years, I think they含羞草研究社檒l still be a real niche market in the overall smartphone market. Growing, but still 含羞草研究社� relatively speaking 含羞草研究社� relatively small.含羞草研究社�
AI CHAT GLASSES
Artificially intelligent chatbots like ChatGPT have taken the tech world by storm, and U.K. startup XRAI Glass is joining the fray with augmented reality glasses.
The company含羞草研究社檚 virtual assistant app was designed to work with smart viewer glasses to help people who are deaf or hard of hearing better understand what含羞草研究社檚 happening around them. Speech is transcribed from other people nearby and the subtitles are displayed onto the lenses or an attached smartphone.
Now XRAI (pronounced X-ray) has integrated OpenAI含羞草研究社檚 ChatGPT technology into its app and glasses setup.
含羞草研究社淧eople can ask questions such as general knowledge or recipes or anything they like,含羞草研究社� CEO Dan Scarfe said. 含羞草研究社淥r they can actually ask questions of their conversation. So, `Hey, XRAI, can you please summarize this conversation?含羞草研究社� Or, `Hey, XRAI, what was the name of the town that we were just talking about?含羞草研究社澓卟菅芯可鐧
For those with hearing loss, it can be helpful to have an AI assistant recap a conversation in which multiple people were talking, the company says.
DIGITAL HUMANS
People might feel better interacting with AI chatbots if they had human faces. That含羞草研究社檚 the thinking at D-ID, an Israeli startup, which launched a new interface for its 含羞草研究社渄igital human含羞草研究社� 含羞草研究社� essentially an online avatar that can work with AI-chat systems to hold conversations.
含羞草研究社淲e had the chatbot in the past. They didn含羞草研究社檛 work,含羞草研究社� said CEO Gil Perry, because they could only answer specific questions with specific answers. Now, 含羞草研究社渓arge language models are bringing huge improvements to traditional chatbots.含羞草研究社�
Generative AI systems like ChatGPT can create readable text and hold conversations based on what they含羞草研究社檝e learned from so-called large language models 含羞草研究社� vast databases of digital books, online writings and other media.
Perry demonstrated by asking a question to the chatbot含羞草研究社檚 face on his laptop, whose response was eerily lifelike. He said safeguards would prevent D-ID含羞草研究社檚 technology from being used maliciously.
含羞草研究社淭he idea here is not to replace anyone and not to convince anyone that what they含羞草研究社檙e seeing is true,含羞草研究社� Perry said. It含羞草研究社檚 just that humans are 含羞草研究社渦sed to communicating with faces.含羞草研究社�
REMOTE CONTROL CARS
At German mobility startup Vay含羞草研究社檚 display, a driver was steering a car around a course marked with pylons. But the car was 1,800 kilometers (1,118 miles) away in Berlin.
The company含羞草研究社檚 technology enables cars to be driven by remote 含羞草研究社渢ele-drivers.含羞草研究社� So far, so standard.
The twist is in Vay含羞草研究社檚 business model, which is a cross between taxi service and car rental. When a user hails a ride, a tele-driver will steer one of its electric cars to the pickup point for the customer, who will take over the driving duties. At the destination, the car will be taken away by a remote driver. No need to park.
The company says it含羞草研究社檚 the first in Europe to be allowed to operate cars on public streets without a human driver inside. It has 20 certified tele-drivers so far and plans to launch the service soon in Germany and the U.S.
含羞草研究社淲e含羞草研究社檙e talking, you know, hopefully months,含羞草研究社� CEO Thomas von der Ohe said.
One of the main goals is to rid city streets of cars that are parked and not used for most of the day.
The service will be 含羞草研究社渁 big step to start creating an alternative so people don含羞草研究社檛 buy the second car or the third car maybe in the near future,含羞草研究社� von der Ohe said. 含羞草研究社淎lso not the first car. 含羞草研究社�
AUGMENTED REALITY EXPERIENCES
Software company Amdocs demonstrated AR technology that could be used for 含羞草研究社渘ext-generation immersive experiences含羞草研究社� for both fans and security staff at big-ticket sports games.
For example, soccer fans attending a match in person could buy a package of extras for their AR glasses, including exclusive replay videos and live stats shown on their lenses to 含羞草研究社渁ugment含羞草研究社� their game experience.
The same glasses also could be used as an extra tool for security staff at the game, with additional safety features including a security database.
In a simulation at MWC, guards were alerted to rowdy fans trying to climb the gates. A known soccer hooligan was flagged on the database, his face and details flashing up on the lenses.
Users, viewing the scene from the guard含羞草研究社檚 perspective, scanned the crowd as the glasses picked out faces before identifying the suspect so he could be apprehended 含羞草研究社� an unsettling display bordering on Orwellian.
