What is Usability Engineering?


From Introduce to Social Computing Post that i posted, I told you that Usability Engineering is a field that is concerned about human-computer interaction and try to make computer interface to have a high usability for user to use. But in real, there are no clear definition of them. From my searching, many post also told that Usability Engineering is a process focuses on user-centered design (UCD) and try to ensures good usability of product.

Usability Goals

To ensure that the product has a high usability, there are 4 core evaluation paradigms to measure it.
– Quick and Dirty
– Usability Testing; measures typical users performing real tasks and recording the time taken or number of error.
– Field Studies; done in users natural setting to identify opportunities for new products and determine requirements for design
– Heuristic or predictive evaluation.

Some information come from Usability Engineering, Lecture 3, Social Computing Course. And this post is part of my lecture 3 review.
