  2. E-mail Reports Design ideas Presentations Computers Support Human-Human Communication (HHC)

  3. Traditional Software Interfaces • Force translations to formal representations • warp human-human communications

  4. Traditional Representations • Rigid and unambiguous • hard to mix (e.g., few tools support rough sketches) • warp perceptions of the viewer • Increase time • encourage precision • Inhibit creativity • “tunnel vision”

  5. Informal Communications Styles • Speaking • Writing • Gesturing • Sketching Informal UIs allow users to work naturally

  6. Architectural design Presentations UI & Web Page design Note taking Application Areas

  7. Outline • Informal User Interfaces • Approach to the Web Design Problem • SILK: Background • SILKWeb: First Iteration • An Informal Experiment • Future Plans • Collaboration with NEC

  8. The Web Design Problem • How do we improve the Web Design process to maximize creativity and expressiveness? • In early phases, precision is deadly • both for designers and evaluators • Lots of designers sketch anyway

  9. SILK: Background • Design GUIs by sketching • Sketch GUI screens and widgets • system recognizes widgets as drawn • Specify widget interactions in storyboard • Simulate interaction in “run mode” • Output formal UIs (VB, Motif, Java) to transition to next stage

  10. SILK

  11. SILKWeb: SILK Extensions • Primitive Recognition • line text circle rectangle bullet triangle

  12. SILKWeb: SILK Extensions • Widget Recognition hyperlink table

  13. SILKWeb: SILK Extensions • Widget Recognition list text block/ paragraph Also buttons, radio buttons, check boxes, listboxes...

  14. SILKWeb: SILK Extensions • Navigation Bars

  15. SILKWeb: SILK Extensions • Gesture Recognition

  16. SILKWeb: Transformation • HTML  SilkWeb transformation

  17. SILKWeb ® HTML • UI widgets ®HTML form elements • Layout and positioning is main concern • Code generation considerations • multiple client platforms • competing standards • readable, maintainable HTML

  18. Not compatible across browsers... SILKWeb ® HTML • Cascading style sheets w/ absolute positioning

  19.  Leads to obfuscated code... SILKWeb ® HTML • Lowest common denominator: HTML Tables

  20. ® ? SILKWeb ® HTML • Automatic content generation • images • text • links • Site management • storyboard ® directory structure

  21. HTML ® SILKWeb • Parsing HTML • JavaCC • Generating a sketchy representation • library of sketches, or • rendered on the fly • Preserving existing code • “Roundtrip HTML” - Macromedia DreamWeaver

  22. Informal Experiment • Study w/ students in graduate UI course • paper, pencils, markers, scissors • web design tasks • goal: Learn how people sketch to represent ideas about structure and navigation • Caveats: these are not designers!

  23. Observations: Links • Everybody used some variant of this

  24. Observations: Margins • Almost everybody did this

  25. Observations: Content IS King?

  26. Future Plans • Study, interview, observe professional web designers • Apply study results to storyboard • Java Port • want to be able to distribute • Ink Infrastructure brings together several informal UI initiatives

  27. More Future Work • Lazy vs. Eager recognition tradeoffs • recognition often annoying & attention consuming • Moving back & forth across “formal” barrier • formal informal • Integration with later design phases • Collaborative SILKWeb • remote collaboration • LiveBoard • Visualization of Storyboards

  28. Conclusions • Need more study • how do people really sketch? • just because they do it one way, doesn’t make it good • Need to talk to web designers • "Content is King" in early design? • infiltration of other design styles • Java/JavaScript/DHTML/Flash, XML, Fusion

  29. Collaborations with NEC • How does SILKWeb fit into the larger design process? • How can we use these tools in team environments? • collaboration (annotation?) • source code control • How can we better integrate with multimedia?
