HMI applications can be developed for standard Windows WinForm applications, Window Presentation Foundation applications, or web applications.
Windows HMI applications are the most compatible with operating systems ranging from Windows 2000, XP, Server 2003, Server 2008, Vista, and Windows 7.
WPF HMI applications provide the best user experience and richest set of controls for Vista and Windows 7 operating systems.
Web HMI applications provide user interfaces for smartphones like the iPhone and Droid cell phones, and for non-Windows operating systems like the iPad.
