Computer-Assisted assessment of children drawing movements

Abstract

The study used a computer-assisted assessment of children's drawings to investigate the relationship between schooling and fine motor skill development. 62 children from grade 1-6 performed specific drawing tasks (horizontal line, vertical line, square and circle) on a digital tablet. Six features, namely drawing time, velocity, vertical force, horizontal force, impulse of vertical force, impulse of horizontal force were extracted from the dynamic data of drawing. Further analysis showed that there was grade effect for some of these features. The results suggest dynamic data analysis could be a valuable tool to reveal the performance characteristic of fine motor ability development.
