The following is a typical user-experience scenario happened
within the Smart Classroom.
Multiple persons enter the room through the door. At the door, there is an audio-visual identification module identifying the entering person's identity through facial and voice identification. If the person is identified as lecturer, he is granted the control right of the Smart Classroom. The visual motion-track module tracks the lecturer's motion in the room. Once he steps into the teaching area, he will be able to use gesture and voice command to exploit the Smart Classroom to give lessons. Persons in the Smart Classroom other than lecturer are deemed as local students. When the lecturer is in the teaching area, he can start the class by just saying, "Now let's start our class." The Smart Classroom then launches necessary modules such as Virtual Mouse agent, Same View agent (which will be talked about later). Lecturer loads prepared electronic courseware by utterance like, "Go to Chapter 1 of Multimedia course". The HTML-based courseware is then projected on the wall display. Lecturer can use hand-motion to stimulate the Virtual Mouse agent to annotate on the electronic board. Several type of hand gestures are assigned corresponding semantic meanings, which cause several operations like highlighting, annotating, adding pictures, remove object, executing links, scrolling pages etc, on the electronic board. Lecturer can also grant speech right to remote students by finger pointing or voice command, like "Li, please give us your opinion". On the Student Board, remote students' photos and some information as name, role, speech right etc are displayed. When a remote student requests for floor, his icon on the Student board twinkles. Once the lecturer grants the floor to a specific remote student, his video and audio streams are synchronously played both in the Smart Classroom and on other remote students' computers.
