Research
My interests are virtual reality and real-time computer graphics;
as well as psychophysics and perceptual psychology and their application in
these fields. I've also worked on low-level, efficient algorithms for the
rendering of quadratic and cubic parametric curves. I research with the
GVU Center's
Virtual Environments Group.
Projects:
Level of detail management
How do different frame rate means, variances, and frequencies affect users?
Level of detail management
Trading detail in the periphery for graphics performance. A win for users?
VR to treat phobias
Can we use VR to treat fear of heights? Fear of flying?
Real-time distortion correction
What can we do about the distortion in head-mounted display optics?
Level of detail generation
Given a complex model, how to reduce detail while preserving recognizeability?
Fast cubic curve rendering
Integer only algorithms for drawing parametric cubics
