Abstract
A computer implemented method for measuring a person's cognitive load comprises initially receivingstroke data (FIG., FIG.()) representative of hand-based strokes produced by a personwhile performing a task. A processorselectsa subset of the stroke data FIG.() that meets one or more predetermined stability criteria. A measure indicative of the person's cognitive load based on the subset of stroke data is determined. In this was the user's cognitive load in an objective, uniform and non-intrusive manner by analyzing the user's writing behavior. An analysis of all of a user's writing strokes will bias the evaluation result. The accuracy of the cognitive load measurement is increased by applying stability criteria to select the best strokes for further analysis. By disregarding unstable strokes the computation costs for determining the user's cognitive load is also improved.
