This involves the utilization of digital mechanisms and tools in order to generate drawing directly from the hand of the artist. This is done via an interface that is used to translate the movement into the digital display. A stylus is used to illustrate on the digital canvas.
Tablets and cellular phones come with this stylus that can incorporate your manual drawing into the digital arena. You can use bitmaps when you want to specify the colours of each pixel. The ability to instantly digitalize a drawing with the help of technology is similar to magic in many ways.
