The default layout for the instructor appears in Figure 2.1.1.1.

Figure 2.1.1.1: Instructor interface overview.

The roster is a widget that only appears on the instructor's interface. It consists of a list of all the students attending the class. It is used control student's permissions and to communicate with students. Instead of the roster, students have a communication toolbar on their interface. It consists of tools that allow the students to communicate with the instructor, as well as a volume control. They will all be discussed in further detail in later sections of the requirements. These widgets will be discussed further in Section 2.5 and in Section 2.7.

The whiteboard is the main widget of the eClass. It displays the current slide, all of the currently visible layers, and allows users to draw and type directly on them. The whiteboard will be discussed in more detail in Section 2.3 and Section 2.4.

The drawing toolbar contains all of the drawing tools. These are tools that can be used to freehand draw, draw different shapes, and type text all on the different layers. All of the visible layers appear on the whiteboard, so essentially the user can doodle directly on top of the lecture slides. For more information on the drawing tool bar, please see Section 2.6. The Layer management panel allows the user to control the different layers. They can do things such as hide layers, create new layers, and change the order of the layers. See Section 2.3.3 for more details on the layer management panel.

The navigation toolbar has all of the tools for navigating within and between different lecture slides. It allows the user to do things such as step through the subsections of a slide, and zoom in. Sections 2.3.1, 2.3.2, and 2.4.1 go into more detail on slide navigation.

The notepad is the widget for taking text notes during a lecture. It allows students to take primarily text notes that they can save and view later on, and it allows instructors to add notes to themselves so they don't forget to discusses a certain point during their presentation. The notepad is discussed in greater depth in Section 2.4.3.

Figure 2.1.1.2 shows an expansion of the command menus.
