In this demo, the relation between roundness and the phase relation between X and Y is shown. The difference between round and sharp handwriting is that in the latter case, wrist and finger movements are more in phase.
Round handwriting is characterized by independent wrist and finger movements.
In the limiting case, the phase is 90 degrees, yielding circles. This is not exactly the same as phase shifting, but has a similar effect on the handwriting shape. Within limits, a given handwritten word can be twisted from round, counter-clockwise looping, via normal, to sharp and clockwise bending. Depending on the letters involved, the trace will become illegible at different delays for different words. Please refer to our Publications when using anything from the shown material.
