Abstract

영문초록 포함|For understanding the appropriateness of evaluating the efficient flow with respect to text presentation, it is important to investigate of how we can design and arrange the information effectively in order to enhance visual perception. This study is intended to suggest the objective way of designing and to identify the existence of efficient eye-flow on text arrangment which would help clarify its relationship with visual communication. In order to evaluate the relationship between text arrangement and its effect, I considered physiological structure of the eye, characteristics of eye movement, and influential elements in typography on the eye movement. Then I selected type size, text line length, and text arrangement; these are the three variables on which my study is based. Later their results were first statistically validated before drawing any conclusion. One hundred subjects without restriction of gender and profession but of age ( ranging between 20 to 35 ) participated in each experiment: their reading time was measured by the 0.01 second. The Analysis of Variance(two-way ANOVA without interaction) was performed for each experiment to determine if the results were significant enough. The p value was 0.0001 which implies that there was a strong consistency among test results. The data suggested the following conclusion: First, in the case of 9 point type size, the reading speed of 70mm text line length is the fastest in 50, 70, and 90mm text line length. For 12 point type size, the reading speed of 100mm text line length is the fastest in 80, 100, and 120mm text line length. The difference between 50 and 70mm text line length is greater than that between 70 and 90mm text line length. Similarly, the difference between 80 and 100mm text line length is greater than that between 100 and 120mm text line length. Second, in the case of vertically elongated text arragement (refer to Figure 6), the reading speed of vertical arrangement is faster than that of horizontal arrangement. And the reading speed of left-to-right arrangement is faster than that of right-to-left arrangement, Third, in the case of horizontally elongated text arrangement(refer to Figure 7) , the reading speed of vertical arrangement is also faster than that of horizontal arrangement. Finally, based on the above results I found that there is a consistent relationship between type size and text line length, and the following discovery was made : the most effective ratio of type size to line length is approximately 1:8. Comparably speaking, a long length of text line is rather comfortable than a short length of text line to read. On the other hand, judging from the Second and Third results, it seems that the vertical text arrangement is most efficient for reading regardless of text line length. This research supports the view that considering efficient eye movement on text, it is important to understand the mentioned variables that affect visual interpretation. Furthermore, there are other interesting areas of research which would enhance the discovered results such as taking into account not only visual perception but also content understanding.
