It is easier to send out messages or emails from your phone on an actual size keyboard instead of using the small phone keyboard. But carrying around a keyboard is too much of a hassle. With this virtual keyboard you can just turn it on and use it. The keyboard’s size is small enough to fit in your pocket so you can take it many places. This device projects a keyboard. Advanced optics track your fingers when you are typing. It uses Bluetooth to connect to your device. Just swipe to turn it on and start typing.
