How Good is your Drawing? Quantifying Graphomotor Skill Using a Portable Platform

Graphomotor skill essential for completing various academic activities such as drawing of shapes or handwriting of text is conventionally judged based on observation in terms of graphic output�s similarity with a reference and often tends to miss other aspects, like one�s pen-tip velocity that can affect the quality of the graphic output. Thus, there exists a need to quantify one�s graphomotor skills while incorporating both pen-tip velocity and the quality of the graphic output (in terms of similarity/dissimilarity with a reference template). Hence, we have developed a tablet-based platform to quantify one�s graphomotor skill in terms of a Graphomotor Skill Index (a single numeric value obtained as a linear combination of pen-tip velocity and quality of graphic output). A feasibility study with eight pairs of typically developing children and those with Autism indicated that the Graphomotor Skill Index can capture heterogeneity in their graphomotor skills suggesting the potential of the platform for assessment of one�s graphomotor skill. � 2022 Elsevier B.V., All rights reserved.
