Algorithms for the integration of Arabic Language in Mobile Phones

This work presents a subject which deals with man machine interfaces. Its objective is to study the data-processing impact of the integration of the Arabic language in mobile phones, in order to make an Arabic man machine interface. The correct display of Arabic characters is essential in a graphic interface, and because Arabic characters change their forms according to the position occupied in a word, it is necessary to make a contextual analysis on each word, to find the correct form of each character. The Arabic language has a different direction of writing compared to other languages embedded in mobile phones, which requires finding a bi-directional algorithm that ensures a correct display of SMS messages. These messages can contain characters of different direction, right-to-left, left-to-right or characters without direction. It allows making comprehensible the display of messages.
