Since the book focuses on rich interactions, I wanted to spend some time on Adobe Flex/AIR.

After designing several large enterprise applications for diverse clients and industries, I’ve noticed some barriers to crafting a great experience in Flex. I think these barriers arise from the relative newness of the technology (and RIAs in general), the initial focus on development over design, and the confidence that Flex can provide a great UX out of the box. But it takes a bit more to make a Flex app really shine. Fortunately, the Flex community is chock-full of talented and motivated developers who contribute amazing resources.

These tips are based on the best Flex resources I have found, and how you can use them to craft a great Flex UX. This is part 1 of 6:

• Play With It: 10 Explorers
• Learn From the Best: 10 Great Flex Apps
• Learn From the Rest: 10 Great RIAs
• Stock Your Toolbox: Essential Resources
• Review Best Practices for Designing a RIA
• Avoid Common Mistakes: 10 Anti-Patterns

Play With It: 10 Explorers

I can’t think of a better way to get your feet wet than to play with these explorers.

I realize I have only skimmed the surface here, please comment with a link to your favorite explorer or gallery for Flex 3.

I presented Designing Web Interfaces on the O’Reilly Webcast today. Almost 1400 people signed up and the actual attendance hit 862. We set the record for an O’Reilly webcast And we had overwhelmingly positive responses to the talk. If you liked the talk & the material then I think you will enjoy the book.

If you did not hear the webcast, check out the slideshare presentation below. It will give you the best flavor for what our book is about (keep in mind much more is in the book with lots more details and guidelines).

The audio will be available in a week or so. Look for a post here when I get the audio to share.

**UPDATE. The actual video & audio of the screencast can be seen on YouTube. Watch it in high resolution.

What happens when you don’t have the on-screen real-estate to display a set of controls? In our book we discuss a number of real-estate extending techniques in the section on Stay on the Page. While discussing Zoomable User Interfaces (Chapter 7) we looked at Aza Raskin & Scott Robin’s Firefox Concept Prototype. We made passing reference to a Slide Over as a way to bring in more content.

I recently spotted a clearer example (from Scott Robbins) of this pattern from an article on Ajaxian. In that article it is called the Page Slide pattern. I like this better than Slide Over, as Page Slide is a more descriptive name for this idiom. This is an excellent article and the pattern provides a nice technique for extending real-estate on the screen.

This pattern really shines in gesture based interfaces, but can be used in mouse-based interfaces as well. One challenge is providing a discoverable mechanism for sliding back and forth. Depending on the design constraints it could be solved by some very explicit call to action links or buttons for activation/de-activation.

Usage

• To reveal additional navigation controls
• In TV or mobile space since controls and/or space is limited
• To expose a configuration panel (similar to the Module Configure Pattern)
• To a lesser extent to reveal help or contextual information (the partial hiding of the related content might make it a poor choice for this)

Challenges

• Discoverability
• Losing context with the rest of the page
• Make the disruption work for you

Recommendations

• Use it sparingly only for major context switches
• Make the animation fast. No reason to wow the user with your ability to scroll
• Make the activation/deactivation dead simple

Other usages, challenges, recommendations? What do like/dislike about this pattern? Are you planning to use this in a future project?

As Bill mentioned in an earlier post, we don’t want to limit this blog to just the principles and patterns found in the book. For that you can check out our Explore the Book section.

This is the second article in a three part series on patterns and principles for RIA design.

Standard Screen Patterns: 12 patterns w/100 examples

2010 Update- 15 patterns and 80 new examples

By Theresa Neil

As Bill mentioned in an earlier post, we don’t want to limit this blog to just the principles and patterns found in the book. For that you can check out our Explore the Book section. In the spirit of that, I want to share an additional set of principles and patterns I have been using for RIA design. While the book takes a much more consumer web site orientation, these concepts are central to enterprise application and web productivity application design and more broad than those discussed in the book.

This is the first article in a three part series.

1. Standard Screen Patterns: 12 patterns w/100 examples
2. Essential Controls: 30 controls for RIA design and development
3. Components for Commonly Requested Features: 15 patterns and examples

With more companies turning to RIA frameworks for enterprise software development, these screen patterns are indispensable for product managers, UX designers, information architects, interaction designers and developers. The patterns rely heavily upon desktop design principles, subtly blended with many of the better RIA components and principles. I’ve included 100 examples to illustrate these patterns, pulled from desktop, Flex/AIR, Ajax, Laszlo, and Silverlight applications.

01. Master/Detail

Master/Detail screen pattern can be vertical or horizontal. Ideal for creating an efficient user experience by allowing the user to stay in the same screen while navigating between items. Horizontal layout is a good choice when the user needs to see more information in the master list than just a few identifiers- or when the master view is comprised of a set of items that each have additional details. Click on thumbnail for larger image OR download the PDF.

02. Column Browse

The Browse screen pattern can be vertical or horizontal. Ideal for creating an custom user experience by allowing the user to start from various entry points for navigating to the item(s) they are interested in.

03. Search/ Results

The Search screen pattern can range from very simple to quite advanced. Ideal for creating an efficient user experience by allowing the user to navigate directly to an item or set of items meeting specific criteria.

04. Filter Dataset

The Filter Dataset screen pattern can be vertical or horizontal. Ideal for creating an efficient user experience by allowing the user to refine a set of known data, or further refine search results.

05. Forms

All Form screens should be approached with a solid understanding of usability and design best practices. Refer to “Web Form Design: Filling in the Blanks” by Luke Wroblewski for reference.

06. Palette/ Canvas

The Palette/ Canvas screen pattern is seldom the right pattern to apply, but it is the only pattern for documenting or creating: linear or non-liner processes; flow diagrams; screen layouts; design/diagram with physical size or layout constraints.

07. Dashboard

A well designed Dashboard will provide: key information at a glance, real time data, easy to read graphics, clear entry points for exploration This is typically not achieved by displaying a single screen of metrics (either in a big table, or just a bunch of graphs). Providing a high degree of customization is no substitute for user research and testing. Stephen Few has a nice book on this topic Information Dashboard Design: The Effective Visual Communication of Data .

08. Spreadsheet

The Spreadsheet screen pattern is ideal for creating an efficient user experience by allowing the user to easily scan, edit and enter information (in bulk). The Spreadsheet should provide the following functionality: standard table features like sort, hide/show columns, rearrange columns, group by (if applicable), global level undo/redo, add/insert/delete row, keyboard navigation, import and export.

09. Wizard

The Wizard/Quick Start screen pattern is ideal for creating an efficient user experience by guiding the user through a complex or infrequent workflow.

10. Question & Answer

The Q&A screen pattern is ideal for creating an efficient user experience by allowing the user to enter known information and receive a solution. Q & A differs from Search in that this pattern should be used to assist users in identifying possible options or a single recommendation in an arena they are lacking expertise (health insurance, mortgages, planning, purchases).

11. Parallel Panels

The Parallel Panels screen pattern can be stacked (showing one at a time) or unstacked (showing all at once). This pattern is ideal for organizing chunks of information that are similar or have interdependent tendencies. Efficiency is gained by keeping the user in one screen. Ideal candidates for the stacked variation of this pattern are simple work-flows with: a high level, visible goal that is fed by multiple inputs, multiple non-sequential steps. This combines a number of the web site patterns outlined in “Designing Interfaces” by Jennifer Tidwell for a single pattern for chunking and displaying data.

12. Interactive Model

The Interactive Model screen pattern is characterized by many interactive elements associated with the key object (a calendar, map, graph, chart, canvas). It is ideal for creating a user experience that is closely aligned with the user’s mental model (a natural fit). Excellent candidates for this pattern are: calendars, maps, gantt charts, what-if scenarios (including calculators), WYSIWYG editors (including photo editing).

Bonus. Blank State

This is the natural state of the application, before any data has been entered or accessed. The book, “Getting Real” by 37signals”explains that a blank state screen is an excellent place to set users expectations. By giving them a preview this can lower anxiety and reduce frustration and confusion. Items to include in a blank state screen include: videos, quick tutorials, help tips, a screenshot of what a fully loaded screen will look like.

Missing Patterns?

Noticeably absent are two patterns that are grossly overused and misused in enterprise software- portals and tabs.

1. Portals- If your market research, business requirements and user feedback lead you to design a portal, follow the same design principles and best practices as the Dashboard pattern.
2. Tabs- Tabs are a component, and ultimately not a screen pattern. They are to alternate between views of data in the same context. If the data structure is leading you to a tab heavy UI design, I have two suggestions. First, reconsider the IA. Use card sorting and/or hire a professional Information Architect to help you for a few days. Second, follow the same design principles and best practices as the Parallel Panels pattern.

You can download a PDF of this post which includes full descriptions of each pattern, as well as best practices .
