Concept keyboard, type letters on your hand

"Hand" is one of the most basic communication tools for human beings, and it is much more "obedient" than other communication tools. A designer named Sunman Kwon has come up with a projected keyboard on the hand, which will make it more convenient for you to send text messages and chat in the future.

It is a portable device designed to replace the traditional keyboard, and it will use 3.5G or 4G technology. With it, you will not only be able to make video calls, but also do many other things.
