Abstract
In recent years, the embedded systems have so many functions that it takes much time to develop the software on them. Specially, user interface applications should be customized for each product, so it's more difficult to reuse them than middleware. The general model based development tools have the function to generate the source code from both screen layout and screen transition automatically. But the interaction between user interface applications and middleware should be made by hands. In order to resolve this problem, we have developed the user interface development tool "Gaudi" with the user interface widgets, which include the interaction between user interface applications and middleware.
