The eClassroom tool consist of two main UI's, an instructor and a student. As mention in section 1.3 eClassroom only works under a pre-configured network with one designated machine and several satellite computers. The designated machine is used by the instructor to present a lecture and students use the satellite machine to view the lecture.Cofiguration details and more about the setup is explained in more detail in section 2.8.1.. When the instructor initially invokes the eClassroom tool from the designated machine,the screen appears as shown in Figure 2.1-1.
