A Study of Sketch Drawing Process Comparation with Different Painting Experience via Eye Movements Analysis

When in a situation where there is a language barrier, facilitate the exchange through sketching is an efficient solution if a person wishes to keep the conversation going. However, not everyone has sketch basis, the method of using sketch to facilitate the exchange requires not only the foundation of sketch, but also the ability to sketch in a short period of time. Therefore, according to design and apply a set of experiments, we focus on analyzing the eye movement data of the subjects in the sketch of imaginary object shapes and compare the differences in the sketch between the experienced painters and the novice. Specifically, we invited 16 subjects to participate in sketching (e.g., a watch) on the canvas, and their eye movement data was collected by a glasses eye tracker while sketching. The results of analysis by Mann-Whitney U test showed that the novice's gaze was skewed to the left and down as a whole, the gaze was scattered, and the fixation on the central position of the picture was not focused and sustained. In addition, experienced painters put the sketch content in the center of the picture to attract the attention of the viewer and effectively convey the important information of the picture. The research results combine technology with art, which can help novice to quickly improve the efficiency and quality of sketch and carry out a wider range of art research and application.
