My thesis, A Differential Approach to Graphical Interation, discusses the use of numerical constraint solving as a basis for the creation of direct manipulation graphical interfaces. It presents mathematical methods for constraint solving, numerical methods for implementation, system architecture design for encapsulating the methods, and examples of interaction techniques and applications created with the approach. The complete abstract is available online. This lamp image is one of my favorite examples from the thesis. It's in Chapter 1. For your viewing pleasure, I've made a bunch of the images from the thesis available in a gallery of pictures from the thesis. This might be your only opportunity to see the pictures in color. |

A Differential Approach to Graphical Interation,
is a 250 page monstrosity. You can grab the huge
postscript or acrobat file, but you are
probably better off just grabbing it in pieces. Save a tree and view it
on the screen.
(update, 10/16/2006) The thesis was typeset in a way (using a bizarre set of LaTeX macros) that I cannot recreate. In fact, most PS->PDF converters still have assorted problems with it. Today, I tried using a newer ghostscript-based ps2pdf, and it seems to work better (Acrobat 7 doesn't work at all!) so the file "thesis-all.pdf" seems to be OK (I haven't checked the whole thing, but many of the problematic pages look OK.) I have not yet converted all of the chapter files.
