Automatic generation of tutorial systems from development specification

Recent complicated software functions have made it difficult for end users to operate them. Thus, it becomes important to learn how to operate them easily and effectively. Employing a tutorial system is the most suitable approach for learning how to operate software functions. A tutorial system demonstrates the how to operate using the actual software. As a result, end users can learn the usage as if they were actually using the software. However, development of tutorial systems requires much time and costs. Therefore, we propose a method of generating tutorial systems based on use case diagrams, sequence diagrams and test cases. In our method, a generated tutorial system shows function names extracted from use case diagrams, the how to operate along with sequence diagrams, and text string input and item selection using data from test cases. The generated tutorial system is then added to the source code for use in AOP (aspect-oriented programming).
