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:
“Translate a book a dozen times from one language to another, and what becomes of its style? Most books would be worn out and disappear in this ordeal. The pen which wrote it is soon destroyed, but the poem survives.”
—Henry David Thoreau (1817–1862)
