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:
“If you tie a horse to a stake, do you expect he will grow fat? If you pen an Indian up on a small spot of earth, and compel him to stay there, he will not be contented, nor will he grow and prosper. I have asked some of the great white chiefs where they get their authority to say to the Indian that he shall stay in one place, while he sees white men going where they please. They can not tell me.”
—Chief Joseph (c. 1840–1904)
