My primary interests lie in assembling and directing multi-disciplinary research teams to explore visualization technologies, human/machine interface design, and 2D and 3D display technologies. I am also interested in transitioning technologies into commercial or otherwise fielded applications. I am currently Human Systems Integration (HSI) Analyst at Northrop Grumman Mission Systems in Newport, Rhode Island, as well as Adjunct Associate Professor of Computer Science at Brown University in Providence, Rhode Island.
A key element of my work lies in understanding how to apply knowledge engineering to effectively enhance human/machine collaboration. My experience with designing and evaluating situation awareness and sensor exploitation visualization systems has convinced me that in complex, high-risk, and time-critical operations -- especially where massive amounts of data are involved -- knowledge-based interactive computing is the only way to manage, organize and present information to decision makers who need to make rapid and confident choices. In addition to my work in knowledge-based visualization and human/machine interface design, my research interests include virtual environment technology, command and control, and decision support systems.

Time-critical domains, such as emergency management, demand fast decisions from expert users under stress. Our Decision-Centered Visualization (DCV) system supports decision making by integrating domain knowledge and knowledge about human situation awareness for time-critical visualization. Efficient information presentation is vital for the user's situation awareness and, in consequence, to his or her task performance. We address the problem of efficiently visualizing both existing and incoming information by connecting domain data types and presentation requirements of the domain's tasks.

In many virtual environment (VE) applications, the VE system must be able to display accurate models of human figures that can perform routine behaviors and adapt to events in the virtual world. In order to achieve such adaptive, task-level interaction with virtual actors, it is necessary to model elementary human motor skills. SkillBuilder is a software system for constructing a set of motor behaviors for a virtual actor by designing motor programs for arbitrarily complicated skills. Motor programs are modeled using finite state machines, and a set of state machine transition and ending conditions for modeling motor skills has been developed. Using inverse kinematics and automatic collision avoidance, SkillBuilder was used to construct a suite of behaviors for simulating visually guided reaching, grasping, and head-eye tracking motions for a kinematically simulated actor consisting of articulated, rigid body parts. All of these actions have been successfully demonstrated in real time by permitting the user to interact with the virtual environment using a whole-hand input device.

A disciplined investigation of "whole-hand" interfaces (often glove based, currently) and their appropriate use for the control of complex task domains is embodied by the design method for whole-hand input. This is a series of procedures -- including a common basis for the description, design, and evaluation of whole-hand input, together with an accompanying taxonomy -- that enumerates key issues and points for consideration in the development of whole-hand input. The method helps designers focus on task requirements, isolate problem areas, and choose appropriate whole-hand input strategies for their specified tasks. Several experiments were conducted to validate and demonstrate the use of the design method. The results of the experiments are summarized and discussed.

In this paper we describe the evolution of a whole-hand interface to our virtual-environment graphical system. We present a set of abstractions that can be used to implement device-independent interfaces for hand measurement devices. Some of these abstractions correspond to known logical device abstractions, while others take further advantage of the richness of expression in the human hand. We describe these abstractions in the context of their use in our development of virtual environments.
