Created a virtual manual keyboard
The idea of a virtual keyboard is not new in itself: a keyboard for laptop computers that is projected onto the surface of a table is a well-known invention. But only the Samsung company decided to emulate the buttons directly on the user.
They invented a virtual keyboard for mobile devices, allowing you to type text directly in the palm of your hand. A small (weighing only 4 grams) Finger Touching screen is mounted on the wrist, a bright, standard-sized keyboard is projected onto the arm with a laser. Then you need to type a message, and it will be sent to the phone via a Bluetooth connection. The concept of the Samsung virtual keyboard is simply remarkable, but the prospects for its development are not clear at all.
