Morgan Dixon's work is truly breathtaking and eye opening, and I would love for that to be a core part of a scriptable hybrid Screen Scraping / Accessibility API approach.

Screen scraping techniques are very powerful, but have limitations. Accessibility APIs are very powerful, but have different limitations. But using both approaches together, screencasting and re-composing visual elements, and tightly integrating it with JavaScript, enables a much wider and interesting range of possibilities.

Think of it like augmented reality for virtualizing desktop user interfaces. The beauty of Morgan's Prefab is how it works across different platforms and web browsers, over virtual desktops, and how it can control, sample, measure, modify, augment and recompose guis of existing unmodified applications, even dynamic language translation, so they're much more accessible and easier to use!

Don,

This is right up the alley of UW CSE grad student Morgan Dixon. You might want to also look at his papers.

Don emails Morgan Dixon:

Morgan, your work is brilliant, and it really impresses me how far you've gone with it, how well it works, and how many things you can do with it!

I checked out your web site and videos, and they provoked a lot of thought so I have lots of questions and comments.

I really like the UI Customization stuff, and also the sideviews!

Combining your work with everything you can do with native accessibility APIs, in an HTML/JavaScript based, user-customizable, scriptable, cross platform user interface builder like (but transcending) HyperCard would be awesome!

I would like to discuss how we could integrate Prefab with a Javascriptable, extensible API like aQuery, so you could write "selectors" that used prefab's pattern recognition techniques, bind those to JavaScript event handlers, and write high level widgets on top of that in JavaScript, and implement the graphical overlays and gui enhancements in HTML/Canvas/etc like I've done with Slate and the WebView overlay.

Users could literally drag controls out of live applications, plug them together into their own "stacks", configure and train and graphically customize them, and hook them together with other desktop apps, web apps and services!

For example, I'd like to make a direct manipulation pie menu editor, that let you just drag controls out of apps and drop them into your own pie menus, that you can inject into any application, or use in your own guis. If you dragged a slider out of an app into the slice of a pie menu, it could rotate it around to the slice direction, so that the distance you moved from the menu center controlled the slider!

While I'm at it, here's some stuff I'm writing about the jQuery Pie Menus. http://donhopkins.com/mediawiki/index.php/JQuery_Pie_Menus

Morgan Dixon's Research Statement: http://morgandixon.net/morgan-dixon-research-statement.pdf

Community-Driven Interface Tools

Today, most interfaces are designed by teams of people who are collocated and highly skilled. Moreover, any changes to an interface are implemented by the original developers and designers who own the source code. In contrast, I envision a future where distributed online communities rapidly construct and improve interfaces. Similar to the Wikipedia editing process, I hope to explore new interface design tools that fully democratize the design of interfaces. Wikipedia provides static content, and so people can collectively author articles using a very basic Wiki editor. However, community-driven interface tools will require a combination of sophisticated programming-by-demonstration techniques, crowdsourcing and social systems, interaction design, software engineering strategies, and interactive machine learning.
