These are the most innovative inventions of the year, according to the largest technology fair in the world | Technology

Every year, hundreds of companies compete to show the world that their devices are the most modern and amazing on the planet. They try to get an award in the CES, the largest consumer technology congress in the world, held between January 7 and 10 in Las Vegas. The CTA, the organizing association of the event, grants since 1976 its innovation awards to recognize "the most influential and innovative fields of the industry". The jury is composed of experts in the sector and in the media, designers and engineers. These are some of the most original winners of this year:

Health & Wellness
The key to good oral health is to locate and eliminate any rest between the teeth before it becomes a major problem. Although millions of people in the world brush each day, they don't know if they are doing it correctly. The winning device in the health and wellness category seems to have the answer. Colgate Plaqless Pro is an electric toothbrush that has optical sensors in its head to detect any accumulation in real time. A ring of light on its handle indicates to the user if a certain area of his mouth is completely clean.

Smart home
A bed capable of heating has been made with an award in the category of smart home. Climate 360, by Sleep Number, balances the temperature and optimizes the body's natural sleep cycles. Specifically, it can heat the bed to 100 degrees and cool it to 12. According to the company, clinical research has shown that this bed can reduce body temperature throughout the night to keep the user comfortably asleep and thus decrease the number of times wake up

Robotics
Meeting Owl Pro is a small device with camera, microphone and speakers that seeks to convert any meeting or conference room into a smart room. It is one of the winners in the robotics category. Its objective is to improve the interaction between people and teams that hold remote meetings. Once placed in the center of the table, observe everything that happens around you. Through vision and voice recognition systems and predictive technology, it is able to focus and zoom on who speaks and knows the room.

Virtual reality
Although it may seem a somewhat futuristic invention, the winner of this technology allows users to play video games or navigate applications with the mind. NextMind offers a new way of interacting by connecting the brain directly with virtual reality helmets or augmented reality creating a totally immersive experience. Its technology incorporates algorithms based on artificial intelligence that decode the user's intention and translate neuronal signals into digital commands. Just by putting the device on the back of the head, it would be possible, for example, to navigate an app without the need for traditional controls or accessories.

Video screens
Mobile devices have changed the way audiovisual content is consumed and created. When transmitting a vertical video from a smartphone to the TV, the experience may not be the most appropriate. But imagine that it was possible to rotate the TV to take full advantage of the screen. This is what Samsung intends with Sero, which means vertical in Korean. This TV designed for millennials and Generation Z has a rotating screen and has won an award in the category of video screens.

Gaming
In the gaming category, the prize has been taken by a murder board game called St. Noire. In it, players become detectives and must solve a murder in a small town. To do this, they must interrogate suspects, find clues and try to deduce which character is lying. Although its argument reminds of any traditional board game without an iota of technology, the novelty is that throughout the game - which lasts about 30 minutes - interacts with Alexa, Amazon's voice assistant.
