Summary
So far, we have mostly described ideal and typical environments. In this chapter, we will discuss some issues that designers need to consider when building multimedia systems. We call this chapter “The Human Factor” because the content of this chapter deals with effects that can be observed when multimedia systems are exposed to human beings. Of course, ultimately, all computer systems are made to be used by us human beings.
Principles of User Interface Design
Most of today’s applications, especially ones that support multimedia in any way, use a graphical user interface (GUI), that is, an interface that is controlled through clicks, touch and/or gestures and that allows for the display of arbitrary image and video data. Therefore, knowing how to design GUI-based applications in a user-friendly manner is an important skill for everybody working in multimedia computing. Unfortunately, with the many factors that go into the behavior of a program and the perceptual requirements of the user, there is no unique path or definite set of guidelines to follow. Here is an example: Is it better to have the menu bar inside the window of an application, or is it better to have one menu bar that is always at the same place and changes with the application? As we assume the reader knows, this is one fundamental difference between Apple and Microsoft’s operating systems – and it is hard to say one or the other is right or wrong. However, some standards have evolved over many years, using research results and feedback from many users. These standards can be seen in many places today in desktop environments, smartphones, DVD players, and other devices.
