Many pen movement recording systems capture, not only the x and y coordinates of the pen top, but also axial pen pressure, an x an y tilt or altitude and azimuth of the pen barrel. Handwriting movement measurement systems can capture: x = Horizontal coordinates; parallel to the baseline in Western script
If the pen is continuously pressed against the paper, the galvanometer must be strong enough to move the pen against the friction of the paper. To lessen the strain on the galvanometer the pen might instead only intermittently be pressed against the writing medium, to make an impression, and then move while pressure is released.

It is an important test in the evaluation of patients at risk from glaucoma. [1] Most tonometers are calibrated to measure pressure in millimeters of mercury ( mmHg ), with the normal eye pressure range between 10 and 21 mmHg (13–28 hPa).

Online handwriting recognition involves the automatic conversion of text as it is written on a special digitizer or PDA, where a sensor picks up the pen-tip movements as well as pen-up/pen-down switching. This kind of data is known as digital ink and can be regarded as a digital representation of handwriting.
A Flex nib (or flexible nib) is a type of fountain pen nib that can create different line widths. Due to its non-rigid structure, a flex nib allows a writer to control line width by adjusting the pressure of the pen on paper. Increased pressure will cause the two tines of the nib to separate slightly, allowing more ink to flow onto the page.

Many important refinements were made at this time, including improved temperature compensation and modification of the pen arm, to allow less weight to be applied to the paper, allowing better registration of small pressure changes (i.e. less friction on the nib). Marine barographs (used on ships) often include damping. This evens out the ...
