Here’s what tech giants are betting on next — from robot dogs to smartphones you can wear on your wrist

The Mobile World Congress, the world’s largest mobile show, is a place where device makers show off some of their latest innovations.

And there was quite a lot on display in Barcelona, Spain, this year.

Artificial intelligence took center stage, but there was also plenty of experimentation with different types of screens and first looks at some devices from some of the world’s biggest tech firms.

Motorola showed off a concept smartphone that has the ability to bend along the spine-like hinge, including wrapping around your wrist.

The “adaptive display concept” smartphone from the brand, which is owned by China’s Lenovo,  has an interface that changes depending on how it bends.

It even has a feature to generate a background to match your outfit.

Lenovo revealed a concept laptop with a transparent screen.

A company representative showed how an object could be placed behind the screen. The laptop’s camera can identify it. Artificial intelligence is then used to display information about the object on the screen.

Forget foldables. It’s now about rollables, according to one company.

Tecno, a brand under Chinese firm Transsion, showed off the Phantom Ultimate, a phone with an expandable screen.

The screen expands horizontally after it a user presses the button on the top of the device.

The AI Pin from a company called Humane is a small device that attaches to your clothing.

You can ask it questions and it will give you a response.

There’s also a camera built in so it can take pictures.

Here’s the coolest part: The laser projector beams a menu onto your hand. You can then use hand gestures to navigate.

We posted a video about it on social media here.

Oppo debuted a set of augmented reality glasses it calls the Air Glass 3.

The glasses are equipped with an AI assistant you can talk to.

Tecno showed off an augmented reality glasses product with a video game controller attached.

It allows a user to play games on a big screen by wearing the glasses.

The processing power for the whole system is housed inside the gaming controller.

Xiaomi has spent years talking up its smartphones’ camera capabilities.

This year, the company took it one step further when it announced that it is selling a professional photography kit with its flagship Xiaomi 14 smartphone.

This is a kit that attached to the smartphone and turns it into something akin to a DSLR camera.

Samsung introduced its Galaxy Ring this week.

It’s the South Korean tech giant’s first foray into smart rings.

It is equipped with sensors that can track things like heart rate and aspects of your sleep.

Samsung said that this, combined with its smartwatch and phone, can give users some insightful health readings.

The company is looking to launch it in the second half of 2024.

Chinese firm Tecno showed off a robot dog.

Called the Tecno Dynamic 1, it has a design inspired by a German Shepherd, according to the company.

In a demo, the dog danced to a beat, jumped around and shook hands with a person.

Other companies like Xiaomi are also developing robot dogs.

Xiaomi debuted its first ever electric vehicle, the SU7, in Europe this week. The car is not yet on sale and it’s unclear if Xiaomi will sell the car in Europe. But the Chinese tech company is keen to flaunt its progress and entrance into the highly competitive EV space. The car took center stage at Xiaomi’s display at MWC.
