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:
“Its whether will ye be a rank robber’s wife,
Or will ye die by my wee pen knife?
Its I’ll not be a rank robber’s wife,
But I’ll rather die by your wee pen knife.
He ‘s killed this may and he ‘s laid her by,
For to bear the red rose company.”
—Unknown. Babylon; or, The Bonnie Banks o’ Fordie (l. 9–14)
