These acts of jotting down the key points from a lecture or adding notation to handouts distributed for the lecture are what we mean by notetaking. The primary purposes of notetaking are two fold: it helps one understand the content of the lecture and also helps the student review and prepare for tests sometime after the lecture. With the rapid penetration of networks and proliferation of powerful digital devices capable of editing, searching, surveying, and myriad other capabilities, many students are looking for better notetaking applications that they can run on these devices. Students have held back from using the word-processing and presentation software that is currently available simply because it doesn't work very well for notetaking, transcribing information from a lecture and from the instructor's comments. In this work, we have developed a network application-based notetaking support system for students that assumes most students already have a tablet laptop, a lightweight notebook computer, or some other electronic device. We will begin by reviewing the various equipment that is commonly used today for lecturing, and the notetaking burden that is imposed on students by different types of lectures. Based on this information, we will then be in a position examine the functions needed by students to design their own notetaking features that help them better visualize and understand lecture content and use their notes to review, and build a system that meets these needs. In order to reduce the amount of input work involved in using the notetaking system, we also assume that the instructor provides students with an initial file and a reference material file that contains a moderate number of objects required by the notes.
