Digital inking systems are becoming increasingly popular across a variety of domains. In particular, many systems now allow instructors to write on digital surfaces in the classroom. Yet, our understanding of how people actually use writing in these systems is limited. In this paper, we report on classroom use of writing in one such system, in which the(More)
There has been much research on the benefits of active and collaborative learning and on its use in computer science courses. As classroom technology becomes more prevalent it is natural to develop systems that support the use of these techniques. We have developed such a system as an extension to Classroom Presenter [2], a Tablet PC-based presentation(More)
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(More)
We have developed and deployed a lecture presentation system called Classroom Presenter in which the instructor uses a Tablet PC as a presentation device. The system has been deployed in courses at the and has been favorably received by students and instructors. In this paper we present an overview of the system and discuss particular uses and advantages of(More)
In this paper, we present a study of how instructors draw diagrams in the process of delivering lectures. We are motivated by wanting to understand challenges and opportunities for automatically analyzing diagrams, and to use this to improve tools to support the delivery of presentations and the viewing of archived lectures. The study was conducted by(More)
Computer Science and Computer Engineering programs across the country are increasingly concerned about the lack of women pursuing computer-related fields. To address this issue, we created a one credit seminar focused on the recruitment and retention of women in technology. The seminar targeted undergraduate women who were co-enrolled in introductory(More)
On April 18, 2004 23 systems scientists from 10 countries (see " List of Participants of Fuschl 2004 ") assembled in the restaurant of the Seehotel Schlick on Lake Fuschl, near Salzburg (Austria), for the 12th Fuschl Conversation (see " Conversations, why, what and how?). A first pleasant was the completely refurbished rooms at Hotel Schlick. These(More)
We are interested in understanding how digital ink and speech are used together in presentation. Our long range goal is to develop tools to analyze the ink and speech channels of recorded lectures. As a first step in this process, we are making a detailed study of instructors' digital ink usage in real university lectures. This work is being done in the(More)
