Then, the research suggested a deterministic algorithm composed of 34 rules that can predict the character based on the use of all of categorizations as atributes assembled in a matrix for this purpose.Ī geometrical approach to letter design has almost always been a marginal phenomenon, and its development has never been smooth. The algorithm is based on four categorizations of Arabic alphabet leters. This research proposes a deterministic algorithm that recognizes Arabic alphabet letters.

Such traits compel to produce a special character recognition method that helps in producing applications for Arabic language.

The Arabic language has many traits that diferentiate it from other languages: irst, the writing process is from right to left second, the leter changes shape according to the position in the work and third, the writing is cursive. On the other hand, character recognition methods for Arabic language are lacking and rare. There are many methods developed for handwriting character recognition especially for Latin-based languages. Hence, the need for fast and accurate character recognition methods that ease the data entry process for users arises. Handheld devices are looding the market, and their use is becoming essential among people. Instead, this paper provides an overview of type design in the 20th century for a specific product, typewriters. Due to the large number of typefaces included in this dissertation, there is no room for an exhaustive analysis of the lettershapes. They offer a description of the type design process in Olivetti, a comparison between typefaces, and some examples of the influence of the typewriter in digital type. The core contents of this research are included in the last two sections. It shows the typewriter as a subsidiary cause of social changes and new habits in typography. The next section, 'Typewriters and text composition', creates a link between the historical background and the machine. These introductory pages explain briefly the history of the typewriter and highlight the particular facts that led Olivetti on its way to success. The first two sections describe the context for the main topic. The research focused on a particular company, Olivetti, one of the most important typewriter manufacturers. The following pages try to shed some light on this part of the history of type design, typewriter typefaces. However, the interest shown in the origin of the machine has not revealed a further interest in one of the true reasons of its existence, the printed letters. The history of the typewriter has been covered by writers and researchers.
