Paper’s No. BUE-FISC – MCAA 09 - Motion Effects of Arabic Typography on Screen -Based Media ABSTRACT: The term of motion Typography is used primarily in a visual communication based on the visual display, as we can adjust the font moving through the screen. We can say that the term of motion typography is a general term which express the motion of the text that requires changing in the spatial arrangement of typographic elements when adding the dimension of time. In This paper we discuss the concepts and the different effects of motion Arabic typography. We show what extent the general characteristics of Arabic writing and letterform impact on the nature of the movement. We represent how we can get Harmonious and fluent movement for Arabic fonts in digital communication media. On the other side, the research present new kind of motion text called “karrataine typography”. Conference Topic: Multimedia Keywords: Arabic Typography, Motion Typography, Kinetic Typography, Fluid Typography, Temporal Typography. 1. INTRODUCTION: There is no doubt that motion typography is a new way of communication, which differs from the methods provided by the static (printed) typography. The ways of expression extend through the digital media, furthermore, they open the possibility of communication with others through time. Unlike the static typography - in the printing media- more possibilities can be detected by adding the dimension of time, which is impossible to be represented in the paper media. The electronic display media differs from its predecessor of paper media in clarity and the ability to view large size of information. An Establishment of a new visual languages to display information can exploit unique capabilities of the computer to create animated and three-dimensional text. The use of motion on the computer screen has a role in changing how we design, read, and interact with typography. After the spread of computer systems, the design and implementation of digital fonts has been developed. This development is accelerating by time, which led to the emergence of new technologies and solutions. In spite of the number of font designers in the world increasingly dramatically – because this specialization is available in many universities and taught in the departments of visual arts or visual communication in the faculties of arts and architecture- it is facing significant weakness in the Arab world, and the number of digital Arabic font designers are too few to be distinct. When we look to the Digital Arabic Font, we find that most of these fonts that have emerged so far did not represent even a part of the aesthetics of Arabic fonts. Despite the good attempts emergence of Arabic letter form in printing fields on the computer, but these attempts were not enough to make the font fits with the logic of movement, without compromising with the aesthetic values for the Arab fonts. All of these make Arabic fonts
