Meng ZHU is a second year PhD student. He has a broad interest in graphics and visualization, with his current focus on adding textures on overlapping surfaces in a volume rendering process in stereoscopic display for ease of human perception. Existing researches have shown that textures of special pattern can greatly facilitate human perception when viewing multiple overlapping surfaces, especially in stereoscopic environment. As volume rendering is widely applied nowadays, it is of practical significance to combine the technique with volume rendering. In the future, he would like to incorporate eye tracking facilities so that eyeball movement can be tracked at real time and responses made to enhance the visualization on the region of gaze automatically.
He holds a BS degree in Information and Computing Science and a MS degree in Operation Research from Beijing University of Technology. He is working with Dr. House towards his PhD degree. Apart from those focuses, he is also very interested in all aspects of C++ and software engineering.
Jonathan is currently a second year PhD student whose recent work focuses on alternate methods of visualizing projected hurricane paths. It is believed that the widely used cone of uncertainty can be a somewhat misleading visualization tool because of the fact that it only has a sixty to seventy percent chance of covering the actual path a hurricane will take. By utilizing both the projected path and historical data, Jonathan is working with Dr. House to create a more complete visualization of the actual paths that might be taken by a hurricane.
Jonathan completed his BS in Computer Science with an emphasis in Fine Art at Clemson in August of 2009. He began working with Dr. House in the spring of 2009 and hopes to pursue research in the application of artificial intelligence techniques in creating and running dynamic, self-sustaining environmental simulations in real-time.

Project Green is a collaborative effort between Clemson University and SC-TAC (South Carolina Technical Aviation Center) to work on the conceptual design of a test track facility including infrastructure components which support R&D in the domain of clean transportation and advanced vehicle communication. The key objective of this project is to develop a feasible test track facility design in order to qualify for a national R&D center on sustainable mobility which can leverage the R&D capabilities of CUICAR (Clemson University International Center for Automotive Research). Our role in Project Green is to develop a 3D interactive visualization that will allow designers to previsualize potential track layouts and associated building placement and design. This will be constructed within a game engine, to provide flexibility in how the site can be toured (1st person within a test car vs. 3rd person following the car vs. flyover birds eye view).Web Demo Mirror
Level-UP: Unveiling Programming

This project is devoted to the development and classroom evaluation of a new approach to the teaching of introductory programming. A key premise in the design of the approach is that programming students should become intimately familiar with the Von Neumann machine model underlying the execution of their programs. The two innovations supporting this premise will be the design and development of an introductory programming curriculum that exposes the student to a progressively more sophisticated set of programming paradigms, and a computing machine simulator that unveils the more complex models of machine structure required to support these paradigms.
Corollary to this will be the design and development of a video game embedding both the curriculum and the simulator. Thus, the fruits of the project should be usable in a classroom environment, with a teacher guiding development of programming skills, or in a game environment where the student is guided through the curriculum by the video game. We plan to use classroom experience, in a university and in a high school setting, to evaluate the approach for both student engagement, and transferable knowledge. In addition, observations and reflective notes from classroom experience will be used to refine and improve the curriculum and simulator design.Read More
Communicating Hurricane Information to Public Officials for Proactive Decision Making

Although the past 30 years have seen major advances in the scientific understanding of hurricane forecasting, there has been a lack of systematic research on the people’s comprehension of this weather information. The National Hurricane Center (NHC) provides forecast advisories, public advisories, discussions, and wind speed probabilities during incidents and tracking software can assist local officials making hurricane evacuation decisions. However, there have been few attempts to scientifically assess the hurricane information that is communicated to local officials. The primary challenges are (1) that most local officials are not trained in the language of meteorology, (2) that most people have difficulty in understanding the probabilistic concepts that are used to communicate uncertainty, (3) the hurricane information must be combined with other information, risks and costs, about which there is little data.
To address these challenges, we are developing a formal model of hurricane evacuation decision making, examining the cognitive processes that are involved in hurricane tracking, so that we can suggest improvements in hurricane evacuation decision training and in hurricane information displays. Our primary contributions to this project are (1) the development of a web-based tool for developing surveys of the effectiveness of hurricane information displays during simulated hurricane events, and (2) the development of new approaches to visualizing the uncertainty inherent in predictions of hurricane behavior.
Eye Movement in Stereoscopic Displays: Implications for Visualization

This project is designed to undertake an investigation of human eye movement within stereoscopic displays, with the goal of improving the perceptual effectiveness of these displays for visualization. While numerous studies have looked at eye motion for conventional displays, there has been very little work on stereo displays. The challenge and the opportunity for eye tracking in stereo displays is that both eyes can be tracked, yielding information on both gaze position on the screen and eye vergence. This will allow the estimation of where the subject is fixating in three dimensional space, not just in screen space. Three-dimensional eye tracking will illuminate how a stereoscopic display is scanned, allowing direct observation of strategies used to explore and interpret information in these displays. This in turn will provide important information to the designers of such displays to increase their effectiveness in transmitting information. Experiments are being done on a unique Wheatstone stereoscope augmented with eye trackers, on an autostereoscopic display, and on a conventional active stereo display.
