Analysis of Dynamic and Static Features in MovAlyzeR

This document details the features extracted from MovAlyzeR trials, including stroke, segmentations, pressure, jerk, and size measurements. It covers static shape features such as slant, straightness error, and loop surface between strokes. The analysis includes dynamic features related to position, velocity, and time parameters. Various samples are compared and evaluated for comprehensive insights into the movements analyzed.
