The radar chip allows the space to operate as a realistic smart mobile device or will no longer require a touch screen

When you first use the touch screen, everyone has the experience of pressing the wrong button, and now the situation is even more pronounced for smart watches and bracelets with smaller screens. A few days ago, Google developed a new technology that can control mobile phones or watches by making gestures and actions only by air. It is expected to completely change this situation.

Researchers say the technology is expected to disrupt the entire industry's game rules, making the sleek space in the movie "Minority Report" a reality on mobile phones and even smart watches. Smart mobile devices may no longer require touch screens and physical buttons.

Ivan Bopplev, Google's human-computer interaction expert responsible for the research, said the project, called Soli, allows the system to track the movements of the user's hand with a built-in micro radar chip. The system has now been able to recognize the extremely subtle movements of the fingers, allowing people to interact with computers and wearable devices. According to reports, Soli uses wide beam radar to identify motion, speed and distance. It works at a radar frequency of 60Ghz (Gigahertz, 10th 9th Hz) and can scan motion at 10,000 frames per second. These actions will all be translated into commands similar to those on the touch screen. The chip was developed in cooperation with Infineon Technologies of Germany and is small enough to be embedded in wearables and other devices.

Previously, camera-based sensor Leap Motion has been launched, similar to Soli, the device can also capture hand movements at high speed, but the disadvantage is that it is large in size and must be placed outside the computer. The Google system, which uses chip-based stealth radar technology, can be embedded in devices.

Boplev said that Soli is incredibly simple and doesn't need to be tracked by the camera, you can put it wherever you want to place it. It can also be part of furniture, cars, wearables, watches, toys, and any place where people need to interact with it can be controlled by Soli.

Soli's technology also helps people interact with objects in the virtual reality world and in games. Sekan Toto, an independent analyst for the Japanese game industry, said that when using virtual reality devices, users have limited vision and are inconvenient to use physical devices. Soli will be able to solve this problem and achieve a perfect combination with virtual reality.

Bopplev said that people already have a variety of control equipment, but the equipment that can accurately capture the details of hand movements in the air is a blank. Later this year, the open source technology of the project will be handed over to developers for further research and development, and there will be more exciting applications in the future.
