As a researcher in the field of human-computer interaction, I am focused on techniques and tools that increase the creativity and productivity of individuals using systems leveraging three dimensional input and output. My current research focuses on Integrated Development Environments for Augmented Reality that are built around software and protocols already seeing broad use. My research methodology is based on a strong interest in understanding and responding to the cognitive frameworks of actual stakeholders combined with a belief that this dynamic is the most productive way to advance the field of 3D user interfaces. My greatest strength lies in bringing a combination of broad technical knowledge and strong communication skills, both verbal and visual, to bear on my relationship with the users of the tools I develop.

My work in the Dynamics Systems area involved multivariable control schemes based on reduced order models. I conducted research on the development of a reduced order power plant model that involved running simulations on the Cray Y-MP system. Through consultations with the SPS Energy company in Lubbock, Texas I replaced the pneumatic control scheme on a high order model with a digital system to reflect recent system upgrades at the target plant.

A development system using Multigen Creator files for both geometry and scene composition. Instead of forcing the user to reposition scene elements in C++ code, behaviors are added directly to the scene in an OpenFlight file.
|PARIS Evaluation Electronic Visualization Laboratory,
The PARIS device attempts to strike a compromise between presenting stereo images on the horizon and at waist level. User study found the setup forced users into reaching and the resulting fatigue discouraged direct hand use.
