Since the invention of scanning devices several decades ago, great revolutions have taken place in the publishing industry. Fonts can be designed on the computer and printing can be done digitally. Complicated shapes like Chinese characters, as opposed to their Latin counterparts, can be designed and generated efficiently. As a result, many Chinese fonts have sprung up in recent years.
In this talk, a technique of evaluating digital Chinese fonts will be presented. It involves an extensive survey of the distinctive features of over 35 typefaces ranging from Kai-ti, Hei-ti (black font), to YY-ti (ya-ya font). They were presented to a large group of subjects in the form of high and low frequency words, characters formed by about 16 different structures, and specific text passages of well-known poems. These textual materials were ranked by all subjects. Experimental results were tabulated and analyzed statistically related to typeface legibility, attractiveness, formal presentation, correlation, factor analysis, multi-dimensional scaling, and demographics of the subjects. These experimental results reveal an effective way of choosing legible digital fonts most suitable for comfortable reading of books, magazines, newspapers, and for display of texts on cell-phones, e-books, and digital libraries. The relationships among legibility, eye-strain, and myopia, will be discussed.
