Persian Typography as Visual Messenger Media from the Perspective of the Principles of Perceptual Grouping

Typography in today's world is arranged and composed by taking advantage of the countless possibilities and methods of writing, in the framework of formal relationships of letters and within a network of systematic and purposeful relationships so that they carry a special message and meaning in visual-communication contexts. These characteristics have made it a useful visual media. Thus, this research aims to identify the visual relationships between letters and writing in a communication platform such as a poster from the perspective of "perceptual grouping principles" to achieve and discover the visual and semantic features of Persian typography. These holistic principles and holistic approach (from whole to part perceptual experience) refer to the state of formation of some visual and image characteristics that lead to grouping between elements and components. The question of the present research is, what are the features of typography in contemporary posters of Iran, from the perspective of the principles of perceptual grouping? And how is its result in visual and semantic terms? The author aims to apply descriptive and analytical methods to qualitatively carry out the research problem by using observation tools and investigate and explain this issue with perceptual grouping methods and principles. The statistical population of the research is made of Iranian contemporary typography posters, and the sample measuring tool included eleven principles of perceptual grouping. The main findings of this research indicate that for the purpose of transferring message, most designers seek a large and complete perceptual grouping that includes smaller perceptual units within it. Also, grouping typographic elements for "visual prioritization" and "creating focusing points" is important.
