초록/요약
It may be that the background culture of user has any influence on the usability of a system, particularly the language for the user’s interface. The study was conducted on the example system to see if there is any improvement in the usability of the system when the graphical user interface (GUI) language is localized. The GUI of this example system was originally developed in English. This GUI was modified into the Arabic version for the foreign users whose local language is Arabic while maintaining all GUI contents the same. This is in order to see any positive effect on the usability of the GUI and thus the system improvement in effectiveness when the local language is used. The reading system was chosen to be the critical point of the interest. The implementation of the modification was based on the theoretical background of the language effects and the mirroring in the GUI design. The mirroring process was incorporated to modify the layouts of Left-to-Right English language to the Right-to-Left Arabic language. The survey was conducted in two rounds for two groups. In the first round, both group members were first time to experience the system. One group used the English version while the other used the Arabic version and evaluated the system. In round 2, each group used the other version and evaluated it. The results of the survey for both rounds show 5~34% improvement of the usability. In addition, 27~56% improvement in the learnability aspect of the system.
