Andreas, Your work here is wonderful. (I hope my students don't find what you've done and then try to turn it in for their final projects.)
A couple of reactions: a) your notion that "widgets" should be more than just radio buttons, selects and the like, but should also include, maybe, sliders, color pickers, or even sorters, classifiers, mappers, chat rooms, etc., is very appealing. Some standards for the desired functionalities of these "higher order widgets" might be a good idea. Is anyone working on such standards? That might be fun. b) take a look at this color picker http://srufaculty.sru.edu/david.dailey/svg/rainbow.svg -- it is an HSV (or HSB color picker) that allows two different sliders for the value of Hue, one at a more zoomed level. The data I have on human factors for such widgets is entirely inconclusive, though I believe it to be demonstrable that humans do quite better in HSB space than they do in RGB space. c) depending on how we take the task of a slider: are we merely choosing an approximate value within an interval, or are we chosing a specific value within an interval, I think the canonical interface differs considerably. How best might we enable a human to choose the number 731,654 (no higher or lower)? Is there a slider which allows people to converge on that exact number more quickly than typing it from a keyboard? How much might we leverage from a single click and drag? I very much like what you have done.
