ViKC looks like an ordinary mobile phone case, but it has a very advanced function. It can project a virtual keyboard, which is perfect for those who are used to typing on a keyboard. This is a very useful feature for people who don't like touch screen input. Put vikc on a smartphone, and a virtual keyboard 100mm away from the phone can be projected on the side, allowing you to use the keyboard to type on your phone anytime, anywhere. The text recognition speed reaches 180 words per minute, or 3 words per second. , enough to meet the input speed requirements of most people. It is currently crowdfunding on Kickstarter and supports Android phones and iPhones.
