Fluid Design Patterns Allison Bloodworth JA-SIG Unconference 11/12/07
What is a pattern? • A pattern is a proven solution to a common problem in a specified context • There may be many different implementations of each pattern • “Each pattern is a three-part rule, which expresses a relation between a certain context, a problem, and a solution” [Alexander 1979].
Organization People • Pedagogical Patterns (Manns, 1996) • Human-to-Human Communication Patterns (Cockburn, 1997) • Organizational Patterns (Coplien, 1998, Cockburn, 1997) • Business Reengineering Patterns (Beedle, 1997) Product • HCI Patterns (Tidwell, 1998) • Software Design Patterns (Gamma, 1995) Process • Steps and Task Patterns (Ambler, 1998; Coplien, 1995) • Process Improvement Patterns (Appleton, 1997) Software Engineering Patterns From: Maximizing Reusability of Pattern Languages over the Web, Homa Javahery, www.cusec.net/archives/2002/javahery.ppt
Why use UI patterns? • To help designers and developers create the proper user interface for a specific context • Design patterns libraries may: • Be very general or organization-specific • Communicate best practices & reusable design knowledge • Prescribe specific guidelines/act as style guide replacements • Connect to component libraries

What are Fluid UI Design Patterns? • Open Source Design Patterns (OSDP) Library • Used for: • Help with implementing components • Document patterns found in Fluid applications (standards) • Bring together patterns from other collections which are helpful to Fluid applications • Space for Fluid communities to grow their own design pattern libraries • ???
OSDP Library Audiences • Junior interaction designers & new designers to the community • Developers who need to design the UIs they build • More experienced designers • Creators of patterns
Pattern Library Issues • Proper granularity for a pattern • Serve one organization or many/all? • Use classification hierarchies or tags? • Use mark-up language to facilitate reuse (e.g. PLML)?
Example: Drag & Drop Pattern • Tells you what to think about when implementing the Reorderer component • Lightbox • Drag-and-drop tabs • Portlet Reorderer
Advice on creating a pattern library • First of all, read all the articles and books etc. related to this topic to get started. • Second, it is really important to understand organization's culture to select suitable patterns and create tool for sharing and managing patterns. • And, when you have created the library, you need to find the ways to keep the library living.

What can you do to help? • How do you currently design and implement user interface elements? • How might you use UI design patterns and Fluid (or other) components? • What additional information might you need?
