“…The shapes of the letters in Arabic typefaces differ from one style to another because Arabic calligraphy was developed as an art form (as shown in Table 1). Research findings have demonstrated that typography plays a critical role in ensuring legibility and readability that should be considered when producing readable electronic materials (Al-Harkan & Ramadan, 2005;Gould et al, 1987;Lee et al, 2008;Ley, 1988;Schenkman & Schmid, 2003;Sheedy et al, 2008;Yau, Chao, & Hwang, 2008). Legibility and readability guidelines, which include typography guidelines, described in the literature are written for English readers.…”

The auditing process is a necessary and integral part of a quality-assurance system. The tendency of using computers in the auditing process is a necessity. This work describes three experiments designed to explore the effects of presenting written material variables on reading speed and comprehension. Five graduate students who consented to participate first completed the font style selection process among six Arabic font styles. "Simplified," "Traditional," and "Koufi" font styles were selected from the typography style selection process to be implemented in the next two experiments. Eleven auditors and fourteen undergraduate students with and without knowledge of using computers participated in the second and the third experiments. The font types (Simplified Arabic, Traditional Arabic, and Monotype Koufi) and the font sizes (10, 13, and 16 point) were independent variables in the second experiment. Color combinations (white/black, black/white, blue/white, and white/blue), column types (one and two columns) that are crossed within auditors and naive students were the independent variables in the third experiment. Reading speed, comprehension levels in terms of accuracy of answering recognition and recall questions, and discomfort subjective measures were the dependent variables in both experiments. Results showed that the quality-assurance auditors were superior to students at reading speed and comprehension. A 13-point Simplified Arabic font type was better than other font type and font size combinations in terms of reading comprehension and discomfort measure. In addition, white characters on a black background screen color was superior to other character\screen color combinations in terms of reading speed, reading comprehension, and discomfort measure.

“…This evaluation technique always sets a human-involved experiment firstly and lets subject to take part into it; and then makes some assessment indices or standards to evaluate the application effect. For example, in [45] the authors utilized a software to study the legibility of Arabic digital typeface. The pixel shape and colour, the matrix pixel density factors were considered.…”

A kind of Subjective Imaging Effect Assessment (SIEA) method and its applications on intelligent imaging terminal design in engineering site are presented. First, some visual assessment indices are used to characterize the imaging effect: the image brightness, the image brightness uniformity, the color image contrast, the image edge blur, the image color difference, the image saturation, the image noise, and the integrated imaging effect index. A linear weighted function is employed to carry out the SIEA computation and the Analytic Hierarchy Process (AHP) technique is used to estimate its weights. Second, a SIEA software is developed. It can play images after the settings of assessment index or assessment reaction time, etc. Third, two cases are used to illustrate the application effects of proposed method: the image enhancement system design for surveillance camera and the imaging environment perception system design for intelligent lighting terminal. A Prior Sequential Stimulus (PSS) experiment is proposed to improve the evaluation stability of SIEA method. Many experiment results have shown the proposed method can realize a stable system design or parameters setting for the intelligent imaging terminal in engineering site.

“…1 Previous studies have done this by way of challenging the restricted area of training that uses traditional calligraphy methods (Attaran, 2012). One of these is demonstrated by analyzing correct responses and performancesubjective ratings, that Arabic letters in square matrices (e.g., 8 Â 8) are more readable than in rectangular matrices (e.g., 7 Â 9) (Al-Harkan & Ramadan, 2005). Additionally, there is a new method using the C4.5 machine learning system for the recognition of Arabic texts (Amin, 2000).…”
