A Legibility Study of Chinese Character Complicacy and Eye Movement Data

Abstract

This study investigated the correlations between the complicacy and legibility of Chinese characters by using eye tracking analyzed with structural equation modeling. 13 university students, 6 men and 7 women, with a mean age of 21 yr. (SD = 1.7) participated. The results indicated that block types affected legibility and that saccade amplitude, number of fixations, and complicacy differed due to diverse character structures. Structural Equation Modeling showed that the number of strokes, number of nodes, and image density in stroke complicacy affected the number of fixations and saccade amplitude in eye movement data. Constructing a character complicacy and eye tracking information model to investigate the correlations between Chinese character features and human viewing behavior can provide guidance for Chinese character recognizability and type design.

Analysis of Variation in Viewing Distance among Low Vision Individuals under Chinese Free-Viewing Condition

“…Future studies should consider the following issues. First, the e ects of visual complexity with regard to character size should be examined, because a previous study found that the di culty of the optotypes used on eye charts in uences the variation in viewing distance (Ma & Chuang, 2015). Although the current study referred to previous studies (e.g., Peli, Burns, Farell, & Moor-Page, 2006;Wang, He, & Legge, 2014;Wang, He, & Legge, 2018) and calculated the perimetric complexity of each character (Endnotes: Fig.…”

Eye movement parameters for performance evaluation in projection-based stereoscopic display

“…Research in different fields might focus on different eye movement parameters (Rodrigues & Rosa, 2017). Ma & Chuang (2015).…”

“…Despite the availability of many eye tracker publications over the past two decades, there is still little information available on the interrelationship among eye movement parameters. Previously, Ma & Chuang ( 38 ) investigated the correlations between the Chinese characters stroke complicacy and eye movement parameters by utilizing structural equation modeling (SEM). However, the path coefficient was found low (β: 0.17) and the loading factor of saccade amplitude was less than 0.70 (p-value < 0.10) indicating that saccade amplitude was a not a strong predictor for eye movement parameters in the model (Figure 1).…”
