Automotive User Interfaces and Interactive Vehicular Applications

Scene Composer also provides interfaces to query information
about the available scenes and widgets to enable the integration
with behavior modeling tools.
CGI-Studio is a tool suite based on the concept of controller
widgets that allows building seamlessly integrated toolchains for
2D and 3D-GUIs development, analysis, and improvements in
ergonomics- and concept-departments.
7. SUMMARY
The model-driven development of automotive HMI offers clear
advantages compared to a manual implementation. However, it is
crucial to have appropriate tool support available for creating and
editing these models efficiently.
Present GUI modeling tools are based on widgets that come with
a specific appearance which is manually programmed. This
hinders a seamless integration of the tools that visual designers
use to create GUI design draft and those applied to develop the
models for generating the final HMI software. When it comes to
3D GUIs this approach is no longer possible.
Reducing the role of the widgets to a controller one enables to
overcome this problem. Their appearance is defined by
connecting these widgets to elements in a scene graph that was
created using standard tools in graphic design domain. This
approach is also applicable for creating widgets in 3D GUIs.
Time-consuming reimplementation of design drafts is avoided
reducing the efforts to adopt new GUI designs. This, in turn,
raises flexibility in the HMI development and helps to achieve
shortened development cycles.
