A cluster of computers can be used to render large amounts of data at very high resolutions. One application of clusters is scientific visualization, which often involves the display of large data sets. This paper describes a prototype system that allows oceanographers to interactively view oceanographic data using a cluster...
As non-renewable resources dwindle and costs increase, it becomes ever more important for people to understand and control their electricity usage. Eco-feedback devices are being developed to increase user awareness and reduce consumption. In order for feedback devices to be successfully adopted into the home, however, they must be appealing...
This thesis presents a novel technique for retiming keyframe-based animation. We call our approach Performance Timing. Keyframing is a standard technique for generating computer animation that typically requires artistic ability and a set of skills for the software package being used. From our experience observing novice animators and their work,...
Graph-based approaches for sequencing motion capture data have produced some of the most realistic and controllable character motion to date. Most previous graph-based approaches have employed a run-time global search to find paths through the motion graph that meet user-defined constraints such as a desired locomotion path. Such searches do...
Virtual environments and simulations are being used increasingly to both visualize and understand data as well as to create scenarios for training and analysis purposes. In this paper, we are interested in the use of simulation and visualization of interactive virtual agents to create realistic motions for training scenarios. We...

Communicating dynamic motion content, such as exercise, with a static medium, such as paper, is difficult. The technology exists for presenting 3D animated exercise content to patients; however, the tools for allowing exercise domain experts to effectively author the content do not exist. We conducted two formative studies with exercise...
In this dissertation, we present a user-in-the-loop method for the design of an interactive motion data structure that benefits from the advantages of both motion graphs and blend-based techniques. Our novel approach automatically analyzes a traditional motion graph built from labeled motion clips. The result is a more condensed, coarser...
This thesis presents a model for simulating individual pedestrian motion based on empirical data. The model keeps track of a pedestrian’s position, orientation, and body configuration and leverages motion capture data to generate plausible motion. Our model can automatically incorporate a pedestrian’s physical limitations when making movement decisions, since it...
We present an approach for generating a character’s response in anticipation of an impending impact. Protective anticipatory movement is built upon several simple actions that have been identified as response mechanisms in monkeys and in humans. These actions are parameterized by a model of the interaction based on the approaching...
This thesis presents a domain specific visual language designed to allow coaches to create content that exhibits the complex 2D interactions observed in the game of American football. Coaches can visually program the content by using symbols and drawing primitives similar to those that they currently use to design static...
