During automated writing, the azimuth angle around a fixed position changes automatically according to the written form of the letter. Good control of the azimuth angle means that the writer can precisely control the movements of the pen in the horizontal direction, resulting in consistent and precise handwriting.
As handwriting becomes more automated, the number of these angle changes decreases. The more minimal the angle changes, the more fluent the handwriting becomes.
Good control of the azimuth angle is facilitated by practicing finger dexterity and an ergonomic pen grip.
