In terms of sampling rates, I'm going to try video recording a stroke, then we can get a more accurate number. And also tilt angle samples (ideally after finding a protractor).
Fountain Pen is not pressure sensitive. Marker and Pencil are.
Fountain pen is like a thin line segment at about a fixed 20 degree angle. The thinness varies over a narrow range with the stroke 'weight'. The segment length is determined by one of the five 'weights'. So minimum thickness when direction aligns with 20 degrees, maximum thickness is achieved when direction is aligned with 110 degrees. (Seems this is biased to right handers, there should be one with minus 20 degree pitch as well! Will this discrimination never end?!)
Pencil is only type with tilt.
Attached samples:
- notebook with Pencil strokes with various weights, pressures, and tilt, and Fountain pen strokes at different angles (the 'circles' are at least 2 strokes, but hopefully capture all angles for each 'weight')
- notebook with single stroke, video recorded
- the video recording of stroke
- PDF export for each notebook
The stroke started at about 2 37/60 seconds (60fps) and ended 5 41/60 s so 3 4/60 seconds total.
