Samsung unveils wearable phone, smart ring

Recently, at the 2024 Mobile World Congress (MWC 2024) held in Barcelona (Spain), famous brands such as Samsung, Lenovo, Motorola... introduced many technology products with futuristic designs and appeared for the first time at this event.

Phone without app

According to ZDNet, Deutsche Telekom, T-Mobile's parent company, introduced the smartphone but without the app at the event.

Accordingly, this smartphone is integrated with an artificial intelligence (AI) virtual assistant developed by Brain.ai to support users in many tasks without having to rely on any other applications.

Wrist scroll phone

According to CNET, Samsung has introduced the Cling Band smartphone that is so flexible that users can wrap it around their wrist, becoming a smartwatch with a large OLED screen.

To do this, Samsung used a ridged structure on the body including the front, edges and back.

The Cling Band comes in two colors, black and purple. It has a USB Type-C port and a speaker grille at the bottom. A single camera and a heart rate sensor are on the back. The inclusion of a heart rate sensor makes it a watch for tracking heart rate and other health metrics.

However, some experts say it would be uncomfortable to wear a bulky device on your wrist for long periods of time.

At the event, Motorola also showed off a flexible phone that can bend backwards. This allows two people sitting across from each other to watch movies and play games on the same screen. The device also has magnets that can be wrapped around the wrist, turning it into a watch despite its large size. The interface on the phone adapts to how the phone is bent.

However, the above 2 products are just ideas. Currently, the companies have not announced the commercialization time for this product line.

Smart Ring

Samsung's Galaxy Ring is shaped like a ring. It tracks your heart rate, breathing, sleep, and nighttime movement, and can even detect early signs of sleep apnea.

Samsung is also promoting the Galaxy Ring as a companion device to the Galaxy Watch that allows for higher-quality 24/7 health and activity tracking.

It also calculates a user's health score based on a combination of daily activity, sleep, resting heart rate, and heart rate variability. Users can also set specific health goals and receive feedback on their progress via the Booster Card available in the Samsung Health app.

The Galaxy Ring will come in sizes 5-13, marked S-XL on the inside, and will come in three colors: ceramic black, platinum silver, and gold. Expected battery life is 2-3 days.

In addition, at the exhibition booth, Samsung also introduced charging boxes for Bluetooth headphones, smart speakers, smart car keys, golf ball markers... equipped with OLED screens.

Transparent screen laptop

Lenovo brought to the event a Thinkbook model with a transparent 17.3-inch MicroLED screen. When operating on the screen, users feel quite difficult when the cursor moves as if it is in mid-air and selecting applications is equivalent to using Apple's Vision Pro glasses.

Lenovo says the screen can reach up to 1,000 nits of brightness, while the brightness of laptops on the market today is only 400 nits.

In addition to the transparent screen, Thinkbook is also equipped with a virtual keyboard and can transform into a drawing board with technology similar to Wacom.
