The Java programming language has been projected as a universal language fo
r the development of distributed applications. Unfortunately, the project o
f such applications using Java is a complex task, requiring the author to b
e a specialist in this language. This paper presents MUSE, a graphical envi
ronment for the conception of interactive multimedia applications. The soph
isticated user interface of this environment and its new high-level authori
ng model allow the creation of complex applications in a fast and intuitive
way. Due to the large expressiveness of the model, the author may create m
ultimedia applications with logical and temporal inconsistencies. For this
reason, the environment also allows the automatic generation of E-LOTOS spe
cifications, which can be used to analyze and to verify the logical and tem
poral restrictions defined by the author. After obtaining the complete and
correct description of the multimedia application, the environment generate
s the corresponding Java application.
