This year’s CES was different to most; there were no sticky carpets, no terrible coffee and no overindulgent post-keynote parties. That’s because, for the first time in its 54 year history, the world’s largest consumer technology show was an entirely virtual event, meaning that rather than hundreds of thousands of people flocking to Las Vegas, potentially millions could experience it from their own homes.

While notably smaller than usual, there were still plenty of significant announcements, with the majority of big names in tech taking the opportunity to launch new products and showcase what we can expect from tech in 2021. Some things were inevitably different, though, due to the changing times we’re living through.

Pandemic tech

Not only did the global COVID-19 pandemic necessitate a digital-only CES this year, but it also influenced a huge number of the product launches at the virtual show.

With employees around the globe continuing to work remotely – a trend that’s likely to continue beyond the pandemic – PC makers took to CES to showcase devices that focus on flexible working.

HP, for example, launched new business laptops “designed to power hybrid work environments and growing personal creative studios”. Not only are they slimmer and more powerful than ever before, but these new devices – which include the HP 840 G8 Aero, Elite Dragonfly G2HP, and Elite Folio – also boast upgraded camera setups for improved video calling, AI-based audio for simplified collaboration, and built-in 5G connectivity for faster download speeds.

Dell also focused on flexible working, but took the idea step further with a range of monitors that feature a dedicated Microsoft Teams button. This lets users quickly launch the app to make and receive video calls, while the onboard 5MP infrared camera, noise-cancelling microphone and dual 5-watt integrated speakers promise to deliver high-quality video calls.

“People’s expectations of their technology continue to evolve. It’s why we push beyond barriers to create devices that offer better experiences and are more integrated into our lives,” said Ed Ward, senior vice president of Dell’s Client Product Group.

“Our new intelligent PCs make it possible for us to work smarter and collaborate easier, so we can give our best selves in all that we do. Secure, sustainable and smart: that’s the way forward for PCs.”

Other brands took the “pandemic tech” category a bit more literally. Gaming company Razer, for example, showed off a high-tech face mask named Project Hazel, which features "N95 medical-grade respirator protection,” active ventilation, a clear shield so you can see people speaking, and a case that recharges the ventilators and sanitises the mask as it's charging.

Roll up, roll up

At CES two years ago, Royale launched the world’s first foldable phone, and at CES 2021, we saw the arrival of the first rollable handsets. As the term “rollable” suggests, the devices get more screen by unrolling it into a larger display.

First up was the LG Rollable, which features a single display that looks the size of a standard smartphone at first glance, but this screen rolls out to give you a tablet-like experience. It’s not just a concept, either; according to reports, despite only being glimpsed for a few seconds in the presentation, LG plans to release the phone "later this year".

Lesser-known phone maker TCL also showed off its first rollable device at CES. As it’s still a concept, not much is known about the device, but Tiago Abreu, head of the "X-Lab" at the TCL Industrial Design Center, says that the as-yet-unnamed handset can go from a 6.7-inch phone to a 7.8-inch tablet with "a simple tap of the finger."

“The portable 6.7-inch AMOLED Rollable Display re-defines the standard form of a smartphone,” the company said in a statement “With a rollable AMOLED display, it can be extended from 6.7-inches to 7.8-inches with a simple tap of the finger, turning it from a smartphone into a tablet and creating an entirely new user experience with its easily adaptable user interface. The smartphone is less than 10mm thick, making it significantly thinner than the foldable smartphone.”

I like big bots

Of course, it wouldn’t be CES without there being robots. However, while the show is often a showcase for novelty and conceptual robots, this year we saw more advanced androids that could help us adapt to the new normal.

Samsung took the opportunity to show off two new robots called Bot Handy and Bot Care. The former is capable of recognising and grabbing all types of objects throughout the house, which means you can assign it to load the dishwasher, put away groceries, or tidy up your washing. Best of all, it can pour you a glass of wine.

The latter, Bot Care, has a flip-up display attached to its ‘head’ so you can stream video calls. That’s not all it can do, though, as the friendly-looking bot can also measure users’ blood pressure, heart rate, respiration and sleeping state, and will remind them when it’s time to take their medicine.

Health, likely as a result of the global pandemic, was a familiar theme at CES this year – particularly when it comes to robots. UK-based Shadow Robots took to the show to announce that it's secured funding from Innovate UK to explore whether its Tactile Telerobot – a robot that takes the form of a dexterous hand – can be used in manufacturing COVID vaccines for Pfizer.

Perhaps the pandemic had more influence on this year’s CES than we first thought; not only was this the first-ever virtual CES, but it was also a stage for manufacturers to showcase technology designed for the new normal.
