Paul Bakaus' presentation on using jQuery UI to create web application prototypes.

1. RAPID PROTOTYPING
with jQuery

2. PROTOTYPING

3. WHAT IS A PROTOTYPE?
A prototype is an original type, form,
or instance of something serving as a
typical example, basis, or standard for
other things of the same category.

4. “An Experience Prototype is any kind of representation,
in any medium, that is designed to understand, explore
or communicate what it might be like to engage with
the product, space or system we are designing.”
Jane Fulton Suri

5. WHAT IS RAPID
PROTOTYPING?
• Implementing some product functionality as soon as possible
• Not worrying about any details or production issues
• Keeping up an illusion!

6. Rapid prototypers are the
illusionists and magicians of the
web

7. WHY?

8. WHY?
• Engineering the final design can take a long time
• Slow feedback loop for each design interaction
• Communication problems between design and
engineering

9. WHY?
• Exploration
• Validating it works
• Communication

11. DIFFERENT PROTOTYPES
• Wireframes = Walk through prototypes
• Interactive prototypes

12. WHAT IS A PROTOTYPE FOR
US?
• Interactive click dummy
• Modelled after wireframes and/or concept layouts
• Usually targeted at one audience, on one platform

13. A Prototype doesn’t need to validate!

14. NO CROSS-
BROWSER
MESS!

15. Semantics?
Who needs semantics!
SEO?
Who cares, damn it?
Structure, logic...!
LOL!

16. REQUIREMENTS OF A
PROTOTYPE

17. REQUIREMENTS OF A
PROTOTYPE
Layout
Behavior
Data

18. LAYOUT
• Use CSS Frameworks!
• Copy and Paste!
• Use WYSIWYG Editors!
Just get the damn job done!

19. CSS FRAMEWORKS?
• Hides complexity, like any other framework
• Provides templates for grids, columns and more
• Normalizes across browsers

20. SOME TECHNIQUES
• If the floats don’t work, simply position everything
• Use a CSS Framework that comes with columns or a grid
• Utilize all kinds of specific browser technology

21. BEHAVIOR
• Brings life into the prototype
• Describe interactions a user can perform
• Clicks
• Hover
• Drags
• ..etc

22. CSS
• Use CSS whenever possible
• Use it to simulate hover events: a:hover {}
• Use content injection through CSS
• Switch class names in JavaScript, not styles

23. DATA
• Use jQuery’s ajax functions to quickly inject content
• JSONP is your friend!
• $(‘div’).load(‘some.url#content’)

24. USE PUBLIC API’S
• YQL
• Google API’s (Maps, Search, Docs, etc)
• Flickr

25. THE ILLUSION OF SPEED

26. A PROTOTYPE DOESN’T HAVE
TO BE FAST.

27. IT ONLY HAS TO FEEL FAST.

28. PERCEIVED RESPONSIVENESS
• Slow down your interactions
• Use animations and effects to hide a loading process
• Slow interaction makes people understand your prototype!
• Shows the state change
• Shows relationships between elements
• Focusses attention

29. TOOLS

30. THEMEROLLER

31. THEMEROLLER
