Research interests

My inspiration is to ensure that computers are fun to use and make our lives better. In particular, I focus on new ways to interact with information in real-time. I sometimes call this direct manipulation 2.0.

For example, OmniGraphSketcher lets users draw and visually manipulate quantitative data and ideas. And TeraFractal lets users interactively create fractals by playing with a visual version of an iterated function system.

I am also interested in using this approach to take digital textbooks and reference works to their logical conclusion. Why stop at text? Why not create interactive applications for learning, exploring, and referencing each area of study? GraphSketcher starts to do this for economics. TeraFractal starts to do this for fractal math. They are the tip of the iceberg.
