Microsoft has introduced what it calls an "analog" keyboard for Android Wear powered devices.
Still considered a prototype by the software giant, this keyboard uses your handwritten letters to input text on a smartwatch. The keyboard will even allow you to enter special characters, along with numbers and letters.
The keyboard supports square screens with a 320 x 320 resolution and the Motorola Moto 360. When using the keyboard, you simply write in the letter, number, punctuation or special character that you want. While you are drawing on a cursor, the top of the screen prints out what you have just written.
