How To Create A Rich Internet Application

Designing a rich Internet application (RIA) can test even an experienced design team.

Rich Internet application is the web-based application which does not require any additional software installation. RIA is the modern platforms that have characteristics of graphical desktop applications. For creating Rich Internet Applications we use Ajax, Flex, Silverlight, Adobe AIR, and JavaFX are growing in popularity as this shift to RIAs gains momentum.

The hardest challenge is to blend Web and desktop paradigms to create a responsive and intuitive experience. Some paradigms that exist in the desktop environment are ill-suited for the Web, while many of the Web paradigms people are familiar with (paging, explicit refresh) are no longer necessary with RIAtechnologies like Flex and Ajax.
As this space matures, we are learning more and more about which boundaries can be pushed, and which patterns transcend time and technology. While working on the book Designing Web Interfaces, We explored hundreds of Web applications searching for these patterns. Armed with a crazy amount of examples, we distilled the patterns into six principles:

  • Make It Direct
  • Keep It, Lightweight
  • Stay on the Page
  • Provide Invitations
  • Use Transitions
  • React Immediately

But we didn’t tackle the larger topic of how to create a rich application. What is the process? How did products like Mint, Balsamiq, and Wufoo get so good?

This article will outline the process we use to create rich applications, focusing primarily on on-screen design. All of the content is geared specifically toward productivity applications like Software as a Service (SaaS) products and Rich Enterprise Applications (REAs).

Designing for Richness

Adding an accordion or overflow to an application doesn’t make it rich. It could even degrade users’ experiences. Starting a design/redesign at the control or screen level can be an expensive and frustrating exercise. Really good RIAs embody richness on all four of these levels:

  •  Application Structure
  • Screen Design
  • UI Controls
  • Interaction Design

Application Structure

Structuring the application properly will ensure a solid base for the rest of the design process. There are three types of application structure:

* Information: The right structure to use when people need to browse, compare, comprehend information. For example, maps, news readers, dashboards, media players, online stores, etc.

* Process: The right structure to use when people need to provide information in a structured manner. For example, product configuration, setup, or installation; registration forms; tax preparation; checkout; booking travel.

* Creation: The right structure to use when people need to create new content or modify existing content. For example, blogging, illustrating, coding, photo editing, diagramming.

To pick the right one, we need to know the primary user’s goal.
Application structure is based on the user’s goal.

Unless we’re designing a product the likes of which the market has never imagined, identifying the users’ goal can be a quick and painless process. We typically work closely with the business/product owner to write a short story for each of the primary personas. At this stage, it is essential to focus on the goal, not the tasks. We sketch up a storyboard and validate it with an informal user group.

Early storyboard to validate user goals.

Once we understand the user goals, we can pick the right application structure. Some applications will have multiple structures; maybe the user needs to configure a product initially (process structure), but afterward, the goal is to analyze information (information structure). This is completely normal and can be designed for.

Screen Design

We approach to screen design with the “one screen per goal” philosophy. For instance, if the user’s goal is to find a couple of houses and contact a realtor to set up showings, we design one screen to support this instead of creating one screen for every task in the flow. This takes some finesse and discipline, but it will eliminate unnecessary navigation from the most common workflows.


The Master/Detail screen layout can be vertical, horizontal, or even nested. It is ideal for creating an efficient user experience by allowing the user to stay on the same screen while navigating between items. A 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.

Column Browse

The Column Browse screen layout can be vertical or horizontal and a number of levels deep. Ideal for creating a custom user experience by allowing the user to start from various entry points for navigating hierarchal or related data.


Palette/Canvas is the perfect layout for the documentation or creation of linear or non-linear processes, flow diagrams, screen layouts, and designs/diagrams with physical size or layout constraints. The palette can be floating, dockable, or permanently situated. Consider offering a “fullscreen” toggle to give users maximum real estate for creating content.


A Dashboard layout will provide key information at a glance, real-time data, easy to read graphics, and clear entry points for exploration.


The Spreadsheet layout can offer easy edits, additions, previews and total. This type of screen 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 a row, keyboard navigation, import and export, and possibly preview and summary functionality.

Interactive Model

The Interactive Model layout is characterized by many interactive elements associated with a core object (e.g., a graph, calendar, map, sheet music, or text). It closely aligns with the user’s mental model and offers direct manipulation.


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

Refine Dataset

The Refine Dataset layout can be vertical or horizontal and is ideal for creating an efficient user experience by allowing the user to define a set of known data, or further refine search results.

Parallel Panels

Parallel Panels 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 workflows with a visible goal that is fed by multiple inputs or multiple non-sequential steps.


The Wizard layout is ideal for guiding a user through a complex or infrequent workflow. It can be vertical or horizontal depending on the nature of the data.


The Q/A screen layout is ideal for helping a user quickly find a solution. Q/A differs from Search/Results in that it can assist users in identifying possible options or a single recommendation in an arena they are lacking expert knowledge (e.g., health insurance, mortgages, or budgeting).


Any Form layouts should be approached with a solid understanding of usability and design best practices.


Portal layouts can provide a high degree of customization for users. They’re ideal for news sites, but not a replacement for a well-designed Dashboard in a business application.


Tabs can be vertical or horizontal. The Tabbed layout should be explored after all other layouts have been considered. Before choosing the Tabbed layout, double check that this approach won’t make users tab between sections to complete a single workflow. Remember to apply the “one screen per goal” philosophy. A Tabbed layout can work well when there is workflow requiring data to be analyzed from multiple perspectives, as with a list, chart, and heat map.


Browse can provide the best layout for users who goal is to quickly scan and navigate information. It can be two or three columns and typically the primary content is in the leftmost column, with additional related options served up in the right column(s).

UI Controls

Equally important as the layout is the selection of the right UI controls for the screen. Although we try to avoid designing for the chosen framework, we do invest a good chunk of time learning about it so we know what is technically feasible.

While some frameworks have a great set of controls out of the box (JQuery, Flex, ExtJs, Telerik Rad Controls), others offer only a subset of common controls and/or are designed with no regard for usability. Talk with the development team about what is feasible with the chosen framework, timeline, and budget. We use these 30 Essential Controls as our starting point for these discussions.

Once we get the screens 60-70% complete, we transition to prototyping, and those early discussions with the development team prove invaluable.

– What happens when I click here?
– Will this move when I…?
– Oh, cool, can I…?

Instead of designing more wireframes to answer these questions, we build an interactive prototype.

The best practices and examples in Designing Web Interfaces guide the interaction design down a proven path. And the resulting prototype can be played with, tested, refined, and then delivered as part of the development specs. This has proved to be quite a bit quicker, cheaper, and more effective for getting a good RIA developed than our old approach which resulted in a massive stack of wireframes and interaction specs.
