7. Conclusion
As mobile design exists in the context of networked global culture, it is important to embrace a cross-cultural perspective when composing using such technologies in these contexts. Simply put, for mobile design/composing in global contexts, it is less useful to design/compose for each particular culture. Rather, it makes more sense to focus on the shared psychology of mobile users. Interaction design may facilitate cross-cultural mobile exchanges across different platforms, cultures and networks, because it focuses on mediation in terms of learning through cognition. Perhaps because intercultural theories focus on face-to-face communication between individuals (Gould, 2005), such theories might not map well onto interface-based human-computer interaction. As different factors of mediation impact identity, social behavior, and ideas across cultures, new approaches are needed to explain the results of cross-cultural mobile use and mediation in a global network society. This article has examined how principles from interaction design can help with addressing such factors when teaching writing students about composition practices involving mobile technologies in global contexts. In so doing, the author has described how writing teachers can adapt and adopt aspects of interaction design that include modeling designs and users, developing interface and task prototypes, and evaluating specific interaction. These elements provide writing students with a richer understanding of composing in such contexts by focusing on the interconnected nature of users, interfaces, and interaction contexts. By using such ideas from interaction design, writing instructors can help students understand how aspects of culture and technology can converge to affect their communication practices and expectations. They also provide writing instructors with new foundations for teaching students how to re-think ideas of audiences for such contexts. In this way the ideas presented here can provide individuals with a foundation for considering and addressing the ever-changing composition practices created through emerging and evolving communication technologies in an age of globalization.
