In this paper, we report on an empirical exploration of digital ink and speech usage in lecture presentation. We studied the video archives of five Master’s level Computer Science courses to understand how instructors use ink and speech together while lecturing, and to evaluate techniques for analyzing digital ink. Our interest in understanding how ink and speech are used together is to inform the development of future tools for supporting classroom presentation, distance education, and viewing of archived lectures. We want to make it easier to interact with electronic materials and to extract information from them. We want to provide an empirical basis for addressing challenging problems such as automatically generating full text transcripts of lectures, matching speaker audio with slide content, and recognizing the meaning of the instructor’s ink.
