   research combining graphics, HCI and AI, seeks mathematical formulations of artistic and perceptual insight, to build tools for creative minds. my interests span art and visual perception, geometric and anatomic modeling, facial and character animation, sketch-based techniques and interfaces for mobile/XR.      
  Research Themes        

Sketch and Sculpt Interfaces

Often called “natural” approaches to interactive design, inherent limitations in human motor control, artistic skill,  perceptual bias, and  ambiguities of inference,  make it challenging to design sketch/sculpt interfaces. Over the past decade our research has produced a number of groundbreaking systems ilovesketch, meshmixer, crossshade, true2form, and neobarok.


Interactive Character Animation (INCA)

Character setup leaves an animator unencumbered, like a puppeteer, to focus on the formidable task of bringing a character to life. I designed and developed character and facial animation tools for Maya 1.0, with long time collaborator and friend Chris Landreth, and am also part of the Parametric Human Project. My work is focused is on the most expressive parts of our anatomy: face and hands, with a strong recent emphasis on faces through our start-up JALI Research used to drive the face and neck animation of every character in Cyberpunk 2077.


 Mathematical Surface Representations for Conceptual Design

From 2003-2012 (the duration of the MITACS NCE), I led a project on the mathematics of shape representation that produced over 100 publications, numerous best paper and technology transfer awards.


Artistic Projection and Rendering

My interest in this area is to use non-photo realism as a tool for self-expression, as a visual manifestation of Nin's observation
"we dont see things as they are, we see them as we are".


Transcendent Reality

In 1994 I was fortunate to work on the first virtual space tele-conferencing system (left) at ATR. My interests in AR/VR today go beyond an augmented world, to one where reality is subtracted, transformed, or more generally transcended. JanusXR is a step in that direction.
