A conceptual framework for user input evaluation in rich internet applications

Abstract

The more complex an application's user interface is, the more important is the need to guide users filling out the forms-typically by highlighting invalid input, showing/hiding or enabling/disabling particular fields according to business rules. In Rich Internet Applications, these reactions are expected to occur virtually immediately. We discuss aspects to be considered for consistent reactions to user input, and describe how evaluation rules can be formulated for model-driven development. © 2009 Springer Berlin Heidelberg.
