|dc.description.abstract||In today`s world, technology is changing lives across the world. As a result, millions of people are living in the information age and they derive great benefits from the use of their native languages. Unfortunately, people of Eritrea and entire Ethiopia face a myriad of challenges mostly derived from their writing system which consists of a large number of characters that are not fully supported on all operating systems. Currently, all operating systems come without standard Input Method Editor for Tigrigna writing and no input method solution and standard keyboard layout for Tigrigna writing system has existed so far.
Therefore, the objective of this thesis was to design Phonetic-based keyboard mapping algorithm and keyboard layout for Tigrigna. Designing such an algorithm and a corresponding keyboard layout, however, requires scholarly investigation of challenges that are associated with Tigrigna scripts and immediate solution for a number of technical challenges like mapping about 300 characters onto the limited number of keys on standard keyboard, character entry speed and easiness to use among others.
