Pen tilt refers to the angle of the writing instrument during the handwriting process, which can vary over time. In a coordinate system which is determined by the writing surface plane and the vertical pen-tip movement along the axis, all three two-dimensional planes can be discerned, and the angular signals can be delivered by a digitizer:
The rotation of a pen along its longitudinal axis is seldom taken into consideration, as some writers have a habit of continuously rotating the pen as they write. This phenomenon became apparent via electronic pens tethered to the digitizer, whose cords became immensely curled.
Famous quotes containing the word pen:
“Well, I know you haven’t had much experience writing and none at all in pictures. But I’ve heard about you. It all sounded like you’re just the man I wanted for a story about the Navy. I don’t want a story just about ships and planes. I want a story about the officers.... I want this story from a pen dipped in salt water not dry martinis. Do you know what I mean?”
—Frank Fenton, William Wister Haines, co-scenarist, and John Ford. John Dodge (Ward Bond)
