openInstaller User Interface Design
By Jennifer (Jen) McGinn on Oct 30, 2007
Jen McGinn is an interaction designer in xDesign who is working to improve the user experience with the Java Enterprise System installers. She has an MS in Human Factors in Information Design and works out of Sun's campus in Massachusetts.
Last year, one thing I did was to work with a team of Sun engineers and UI designers to create a set of branded interaction guidelines for desktop applications.
[aside] Two weeks ago, I posted an interview with the folks behind the web application guidelines — those are different, because they focus on UI components used in a browser, not a desktop application. [/aside]
The interaction guidelines that I worked on were not component-oriented, but task oriented. Another colleague led the effort on branded system startup, and I led the branded installation guidelines. We may see those guidelines go public at some point, but until then, you can see them in action in the New Solaris Installer (NSI) and the openInstaller framework — even the OpenDS Installer took on some of the guideline design, even though it's a web application.
The openInstaller project team describes the effort this way: openInstaller is an open source community project building a free and comprehensive next generation installer framework. Initial development of openInstaller was done by Sun Microsystems, but is now available under the open source Common Development and Distribution License (CDDL). What's really cool that's not in that statement is that the framework is all Java + XML. I've looked at their code, and if you know a little Java and XML, you can create an installation program quickly and easily.
From an interaction standpoint, there are a few things that I'm particularly happy with. One is how software licenses are presented to the user. Another thing that you may notice is the placement of buttons. The most frequent interaction is placed bottom right, and then other buttons are organized by projected frequency of use from right-to-left. This organization supports the visual scan patterns of readers of most languages better than button placements that we often see, which are grouped in the bottom right-hand corner, but require the user to read all of the button labels from left to right, to find the most frequent interaction.
From a geeky coolness factor, the openInstaller is written in Java and XML that even I find understandable, and the output of that code is two-fold: not only does it render a GUI, but it renders a command-line CUI, that is comparable to what the user would see in GUI mode. As a result, installers written using the openInstaller framework are easier to develop, maintain, and use.
