The Visualization Friday Forum

Fall 2004 * Noon-1pm * D106 LSRC

Sept 3 - Visualization at Duke [ PDF Presentation ]
Rachael Brady
Visualization Technology Group

Visualization applies the algorithms of computer graphics with the fields of perception and representation to communicate digital information visually. Visualization is used for presentations, art creation, data analysis, model validation, illustration, data exploration, entertainment, and cognitive studies. The Friday forum is an opportunity for individuals to share their expertise and experiences in using visualization in their research. This talk will review resources at Duke for doing visualization. In particular, I will introduce some new faces and announce the acquisition of the 6-sided Visroom. Near the end of the hour - for anyone who's interested - I'll take people over to the new CIEMAS engineering building and show them the Visroom/Studio spaces.

Sept 10 - Re-Envisioning the Humanities: Information Visualization and Collaborative Academic Research
[ PowerPoint Presentation ]
Casey Alt
Interdisciplinary Studies + Information Sciences

Over the past few years, humanities researchers have increasingly begun imagining ways in which new digital media tools can expand upon traditional means for data presentation and analysis and encourage collaborative work within their respective fields. One such group of researchers has been the hpsCollaboratory ( ), which was founded by Tim Lenoir and Casey Alt to serve as an organizational group for promoting such interdisciplinary media projects. Two of the hpsCollaboratory's most well-received projects thus far have been online timeline and genealogy applications, which allow communities to collaboratively document their own history via a flexible, graphically-mediated, data-driven web interface. Casey's presentation will focus on hpsCollaboratory's experiences in developing the timeline and genealogy applications, as well as current trajectories of research and development.

Sept 17 - Towards the Development of Computed Tomography Based Virtual Morphometry for Evaluation of Craniosynostosis.
Sean Marshall and Srinivasen Mukundan (speakers), in collaboration with Roger Nightingale, Jeffrey Marcus, and Tracy Stokes
Biomedical Engineering and Radiology

This talk will describe new methods for evaluating craniosynostosis (premature closure of the cranial sutures) in infants that are utilized at Duke Medical Center. In addition, new computer based algorithms are being developed to display and evaluate cranial findings. These approaches will be presented and be the basis of the discussion.

Sept 24 - Passive Stereo Projection in the Classroom: Lessons learned putting a system together
[ PowerPoint Presentation ]
Eric Wiebe and Bethany Smith
North Carolina State University

We will briefly outline our motivation and experience putting together a portable passive stereo projection system for use in the classroom. We will reflect on the lessons learned specifying, constructing and using the system along with giving examples of its current application. Also discussed will be future plans for its use in both the classroom and research.

Oct 1 - Creating Virtual Reality Applications using FreeVR
[ PowerPoint Presentation ]
David Zielinski

Visualization Technology Group

FreeVR allows programmers to create interactive 3-d applications at a low level (C/C++, OpenGL), and yet still maintain a level of independence from input devices and screen configurations. This talk will cover the basic configuration and programming methodologies necessary to begin using FreeVR. Afterwards a demonstration of the 'Virtual Vibraphone' and 'PDB protein viewer' will be given in 130 North.

Oct 8 - Anatomy of a Student Video Project
Sarah Roberts

Office of Information Technology

Get under the hood of the Froshlife digital video project. For two weeks in January, first-year students compete with each other as they work in teams to portray their lives in digital video. The students write, act, edit and present their projects, all created with digital cameras and editing tools. During Froshlife, many student are introduced to multimedia production for the first time. I will discuss the Froshlife project and resources available through the OIT multimedia suite.

Oct 15 - The Topological Media Lab
Dr. Sha Xin Wei
Graphics, Visualization, and Usability Center

The Topological Media Lab is a studio-laboratory focused on the study of gesture, agency and materiality from phenomenological and computational perspectives. The work ranges from tracking finely nuanced hand-movements to modulate the real-time synthesis of musical or visual textures to the construction and choreography of whole responsive media environments based on physics simulations and experimental theater. This research is driven by philosophical questions in science, technology, and performance, and is tested in the public domain as works of experimental art and performance. This talk describes the TML's theoretical agenda, and introduces a few lines of research pursued by artists and engineers in the studio-lab:

- Calligraphic video, real-time synthesis of video textures via physics simulation;
- Gestural sound, real-time synthesis of sound parameterized by live movement;
- Softwear, fabric and body-based instruments;
- Gesture tracking and analysis for expressive technologies;
- Media choreography based on non-scripted, energy methods.

Oct 22- Nurbs modeling techniques in Maya
Anya Belkina

Department of Art and Art History

The talk will offer a quick look at the way in which drawing, painting, photography, typography, animation and video can be integrated in the digital environment of new media. Current work examples in various stages of completion will be used to demonstrate basic Nurbs modeling techniques in Maya. A few preliminary animation tests will show how video and animation is intended to be used for the eventual production of the mulitmedia piece "Nasuh."

Oct 29 - The Interface Surface: An Object for Visualizing Protein-Protein Interactions
Andrew Ban

Department of Biochemistry, Duke University

Geometric representations of proteins are key components in the modern biochemist's tool chest. The interface surface is a construction which addresses how to represent the space between interacting proteins. This talk will provide an overview of both the concept and the recently developed software, Ciel, used to generate and visualize the surface.

Nov 5 - Using AVID for 3D Functional Region of Interest (ROI) Creation
[ Powerpoint Presentation ]
Jeff Hoerle
Computer Science Department, Duke University

Specifying a region of interest (ROI) is a common operation used by neuroscientists to segment the brain.  When considering functional MRI data, the segmentation can be based upon either anatomical or functional datasets.  Traditionally, ROI drawing tools are designed for 2D slice-by-slice selection.  AVID (Activation Visualizer and Interactive Drawing environment), on the other hand, allows users to specify an ROI in 3D for functional datasets, and provides 2D editing capabilities.  This talk will provide an overview of the development of AVID, including design considerations for
creating an interaction scheme for 3D selection.

Nov 12 - Data Mining Techniques for Gene Expression Data
Kamesh Munagata
Computer Science Department, Duke University

This talk will focus on techniques for mining gene expression data curated from micro-array experiments. After a brief overview of microarray technology and the issues involved in processing the data, we will discuss several tools and techniques for spot identification, noise removal, clustering, and feature selection.

Nov 19 - The Sound and the Fury of iPods at Duke
Owen Astrican

Computer Science Department, Duke University

The Duke iPod project has generated interest, discussion, fear, loathing, envy, excitement, passion ... the list of adjectives goes on and on. Duke has made a statement by giving every first-year student an iPod and making loaner iPods available to students in targeted classes using iPods in innovative ways. In this talk I'll discuss why the iPod is a tool for visualization and raise questions about what the future could or should be. I'll discuss my views of the Duke iPod project. I'll provide examples of how iPods are used, have been used, and could be used for educational content --- specifically as part of the class and classroom experience at Duke and elsewhere. I'll also discuss the success and failure of student initiatives in developing software as part of the iPod@duke project.

Although I've been involved with the iPod project since early in the planning stages, this talk represents my views and not those of the Center for Instructional Technology or of Duke University.
