Paper Abstract:
|
According to a survey published by IEEE Computer, HCI is considered by IS and other computing professionals as one
of the most important knowledge areas that are the least taught in their formal education and therefore require the greatest
on-the-job learning. We observed that a significant portion of usability errors in our students projects resulted from
inadequate design on the interaction part of an application, rather than the visual part of its user interface, which
underscores the need of introducing usability concepts early in the development process. However, usability
considerations are often given as an afterthought, instead of an indispensable element of an iterative process, in our
current curriculum. We in this paper describe a model-based approach to integrating usability evaluation into the early
phases of application development. Our initial experience shows that introducing usability concepts early can help
students obtain an in-depth understanding on the basic user-system interaction and also encourage them to make
conscious effort in seeking usability throughout the development process. |
