A smart screen can be defined as a human-machine interface (HMI) that uses interactive graphics displays on a touchscreen to offer users Control of an underlying embedded system. Smart screens come in many shapes and sizesCONTROL ENGINEERING China版权所有, and can be used for applications ranging from ticket kiosks to factory control systems.

To evaluate the suitability of a Adobe Flash Lite based smart screen, QNX developers crated a buliding automation systerm and HMI

        Smart screens are becoming the preferred HMI for a variety of industrial control applications. These smart screens are essentially the same as those for consumer applications. The key differences lie in the underlying applications and the HMI design.
        Where consumer applications may emphasize the “Wow!” factor—with morphing widgets and other non-essential but eye-catching features—industrial smart screens must provide clear and readily understandable interfaces. In additionCONTROL ENGINEERING China版权所有, industrial HMIs must be designed to be consistent over many years and easily updatable. They must maintain a consistent lookCONTROL ENGINEERING China版权所有, feel, and functionality even as the systems beneath them change.
        This requirement for consistency and ease of use does not imply that creating smart screens for industrial applications is less difficult than for consumer electronics. In addition to providing on-screen information and controlswww.cechina.cn, smart screens may need to provide interactive access to layered diagrams, blueprints and maps, embedded videos, and other media. Above all, they must offer industrial-grade reliability.
        Building smart screen HMIs with Adobe Flash Lite allows developers to take advantage of the Flash toolboxwww.cechina.cn, which includes all the elements needed to build a clear, effective smart screen, and which supports the most stringent d
