When it comes to natural user interface, people tend to choose the Android framework, but Android, is too heavy for buiding just a HMI. A popular alternative is the Python based Kivy.

When working with Linux based embedded systems it is essential to cross compile applications to the required target architecture. It is necessary to understand how packages are built, and how the build can be customized to build applications for Linux based embedded systems. This article will be a starting point for discussing about embedded Linux build systems, like Yocto.
