Primary Interest:
- My current research
interests lie in the areas of Human Computer
Interaction and more specifically Computer
Supported Cooperative Work.
In particular I have worked on the design, implementation, and
evaluation of software that enhances the way teachers and students share
written information during class using an electronic whiteboard and
pen-based video tablets or Tablet PCs. This system was originally named DEBBIE.
The system has been greatly enhanced by a company named DyKnow and is now available as a fully supported
commercial product named DyKnow Vision. You can learn more from the
DyKnow Web
Site.
- As an outgrowth of my
interest in DyKnow and pen-based computing I
am on the organizing committee for a conference called WIPTE (Workshop
on the Impact of Pen-based Technology on Education). You can learn
more about WIPTE here.

A description of my Hewlett Packard Teaching
with Technology DyKnow-Related grants can be found here.
·
This student-produced
mini-documentary showcases some ways that students and
faculty at DePauw University are using Tablet PCs and DyKnow software to enhance teaching and learning in
multiple disciplines.
Other Interests and
Projects:
- Working with DePauw
student Alex Iliev, I am experimenting with
using Flash animations to illustrate computer science concepts, especially
by embedding the Flash animations in DyKnow Vision pages. Here are the
animations Alex wrote:
- A Flash animation
that illustrates swapping two variables can be found here
- A Flash animation
that illustrates a FlipFlop can be
found here.
- A Flash animation
that illustrates a relay-based And gate can be
found here.
- Along with other
members of DePauw's Computer Science Department I have an ongoing
interest in conducting research with undergraduates. Much of this
research is supported by a grant from the National Science Foundation
which enables us to conduct a summer REU (Research Experiences for
Undergraduates) Program each summer. For more information on this
program see the Computer Science Department REU Program Home Page.
- Working with colleague
Doug Harms, I have put together a 15 minutes video for use in Computer
Organization courses. The video teaches reinforces standard concepts
from a typical Computer Organization course by showing students how to
program a 1970's era PDP computer. The video is available on the text
book web site for "Computer Systems" by Stan Warford.
A version is also available on YouTube here.
- Working with students
Ian Serlin and Atanas
Vlahov I have been studying the use of water
based computing to reinforce basic concepts from the standard Computer
Organization course. We have created a functional 1-bit half adder that
is powered by water, as well as a series of flash animations that
demonstrate the underlying concepts. You can find a research paper,
pictures, videos, and flash animations related to this project at the Water Adder Web Site.
