Most software applications today provide a graphical user interface (GUI), which facilitates the use of the software by offering graphical and visual elements to the users. The correctness of the user interface is fundamental to the correct implementation of the overall software. Using reverse engineering tools and methods is one of the most efficient ways to understand a system, and to assess its functionality and usability. However, traditional reverse engineering methods are not well suited to interactive elements of a system. This research examines and analyzes reverse engineering techniques of interactive systems written in the Java programming language, with the aim of creating a set of models of the entire system namely, Presentation Models (PModels) and Presentation Interaction Models (PIMs), which are very effective in describing structural and functional behavioral features of the interactive system. This study will also highlight some of the problems that exist in this domain and investigate several possibilities for improving the process.
