Dr. Jankun-Kelly will be giving an invited talk at the Scientific Computing and Imaging Insitute, University of Utah on September 29th. The title of the talk is "A Model and Framework for Visualization Exploration":
Visualization is the process of "making the invisible visible"---the use of computer graphics to depict digitized information. The goal of visualization is insight. However, most past research in visualization, specifically scientific visualization, has been driven by the desire to generate visualizations faster and on a larger scale. In this talk, I will instead focus on the underlying process of visualization exploration itself. I will discuss this process' salient aspects and the fundamental operation a user performs during visualization exploration. This fundamental operation forms the basis of a formal model that encapsulates the visualization process. I will discuss how this form model facilitates visualization collaboration, analysis, and the science of visualization. These applications are enabled via a software framework that implements the model.

Adam Jones will be giving the first talk in the INST 2006 Colloquium Series entitled "Egocentric Depth Judgments in Optical, See-Through Augmented Reality":
Augmented reality (AR) is a method of mixing computer generated graphics with real-world environments. In AR, observers retain the ability to see their physical surroundings while additional (augmented) information is depicted with simulated graphical objects matched to the real-world view. AR has numerous potential applications including medical imaging, navigation, military strategy, and entertainment.
When viewing objects in an AR environment, observers are presented with conflicting depth cues. Many of these inconsistencies are due to the engineering limitations present in the design of head mounted displays. Before practical AR systems can be implemented, we must understand what limitations are present and if there are ways we can compensate for these shortcomings. A key factor in this process is determining how observers perceive egocentric depth relations in augmented environments. Our goal is to utilize methods of perceptual measurement to determine how observers map the positions of real-world and virtual objects.
In our study, subjects are presented with varied real, virtual, and combined stimuli. The apparent locations of the stimuli are then measured using quantitative methods of egocentric depth judgment. The data collected from this experiment provides information as to how subjects perceive egocentric depth with respect to both real-world and virtual objects, as well as further insight into how more functional, ubiquitous augmented environments can be engineered.
Adam's talk will be Thursday, October 26th, at 3pm in the INST classroom.

Dr. Jankun-Kelly will be teaching an informal, three-part tutorial on the Python Programming Language next week. The dates and topics are:
- Tuesday 530-630: Basics
- Wednesday 530-630: Advanced Features
- Thursday 530-630: Useful Libraries
All classes will be in Butler (will shoot for BU 104 for now). Basic and object-oriented programming experience is assumed.
From the python.org site: "Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code." Python is currently in use at NASA, Google, Industrial Light and Magic, and many others.

On August 7th, Dr. Jankun-Kelly gave an invited talk at Brown University regarding the VisLab's liquid cyrstal visualization work. The abstract was:
In this talk, I discuss an ongoing project within the SimCenter at the HPC2 involving the visualization of nematic liquid crystal (NLC) dynamics. These systems have interesting physical properties that have not been adequately realized in current literature, and present a novel, glyph-based tensor visualization scheme to depict NLC dynamics—a Scientific Visualization example. However, this work is based upon an initial need to study the overall behavior of the NLC data over many timesteps, a problem that we have approached by using multidimensional data visualization—an Information Visualization example. My talk will show how these two very different approaches complement each other, and discuss other possible combinations for future consideration.

On Tuesday, 330pm in the Dunn Conference Room, <a href="http://msuinfo.ur.msstate.edu/where/building/mccain.htm" title="Locate McCain Hall">McCain Hall, <a href="http://www.cse.msstate.edu/~tjk/">Dr. Jankun-Kely will be giving a talk at the Bagley College of Engineering's Scientific Computing Working Group Seminar entitled The Marriage of Scientific and Information Visualization: A Physics-based Case Study. Below you can find the abstract.
Information and Scientific Visualization are two disjoint areas of visualization research. Information Visuaization focuses on data with no inherent spatial meaning whereas Scientific Visualization deals with data with a given spatial mapping. Scientific Visualization has a long, productive history at the High Performance Computing Collaboratory at Mississippi State; Information Visualization does not. Can the two live together under the same house?
In this talk, I discuss an ongoing project within the SimCenter at the HPC^2 involving the visualization of nematic liquid crystal (NLC) dynamics. These systems have interesting physical properties that have not been adequately realized in current literature, and I present a novel, glyph-based tensor visualization scheme to depict NLC dynamics---a Scientific Visualization example. However, this work is based upon an initial need to study the overall behavior of the NLC data over many timesteps, a problem that we have approached by using multidimensional data visualization---an Information Visualization example.
