Observations of HCI issues

In this module I learned the scope of issues affecting human computer interaction and the importance of user interface, the impact of good and bad user interfaces. I learned how diversity of user and tasks affect the design of user interfaces. (Dix, Finlay, Abowd, & Beale, 2004)
I learned that as a designer I would have to work in a diverse area like human factors and graphic design to be able to understand what I need in order to design a good interface. (Dix, Finlay, Abowd, & Beale, 2004)
Moreover, I learned about paradigms and how it promotes usability and interactive system. I also learned about the evolution of paradigms which gives a good practice on the history of interactive computing. Another thing that, I have learned that sometimes paradigms can be successful and sometimes might not get a clear reason why they support a user in accomplishing some tasks. (Dix, Finlay, Abowd, & Beale, 2004)
Finally, I realized that humans are the most unpredictable part when it comes to system design since they have higher failure rates under high stress level. Thus the design must provide an appropriate level of feedback without overloading the user with too much information. (Norman, 2002)
