Pen tilt refers to the angle of a writing instrument during handwriting and drawing, which can vary over time. In a coordinate system which is determined by the writing surface plane

    {
    X
    ,
    Y
    }
  

{\displaystyle \{X,Y\}}

and the vertical pen-tip movement along the

    {
    Z
    }
  

{\displaystyle \{Z\}}

axis, all three two-dimensional planes can be discerned, and the angular signals can be delivered by a digitizer. It is part of the ISO/IEC standard 19794-7 for biometric data in signatures.
