Table 2: Segmentation performance of the validation set under different conditions (variations in hand position, drawing speed, and the number of pen lifts). \({}^{*}\) denotes trials where the number of detected and actual segments differed. \begin{table}

Table 3: Number of actual and detected brushstrokes for the clinical dataset. The algorithm correctly identified the number of strokes in 12 of 14 trials. \({}^{*}\) denotes trials where the number of detected and actual segments differed. Table 4 lists the average errors for each feature, averaged across the 5 trials of the validation set with erroneous brushstroke segmentations. The most affected feature was the minimum distance between brushstrokes as well as the minimum in-air time, with errors of 99.31% and 95.34%, respectively. Outside of this, all other spatial features were mildly-to-moderately affected with a cumulative error between 0.88-28.84%. In a similar manner, the temporal features were moderately affected
