Guide To Siemens HMI Software

By Marci Glover


Human-machine interface (HMI) refers to the layer that separates a human being who is using a computer from the machine itself. An example of a human-machine interface is the hardware and Siemens HMI software of a computer, which makes it possible for a single operator to control a machine. The user interface comprises the flow of information to support decision-making, through visual messages - generally provided by a screen or monitor; sound messages - speakers, headphones; control actions - keyboards, buttons, switches.

A set of multiple monitors, devices and control surfaces form a console or management station. From a console, an operator receives notifications and performs control actions. A control room may contain one or more control stations. The control rooms and control stations can be found in many different applications, such as control tower of an airport, control center for police and ambulances and nuclear power plant. The design of the passenger compartment of airplanes and helicopters includes the highly specialized user interfaces.

The most important international conference series in the field of human-computer interaction is the Conference of Human Factors in Computing Systems. It is organized by the Special Interest Group. Human-machine interaction (HMI) defines the means and tools implemented so that humans can control and communicate with a machine. Improving the ergonomics of a man-machine interface in particular the objective of optimizing the development workstation and thus reduce the risks of working on screen (musculoskeletal disorders, eye fatigue, burnout syndrome, stress) is an important aspect. There are many ways for people to interact with surrounding machinery. These ways are very dependent on interaction devices.

The term human-machine interface is sometimes used to refer to what is best described as direct neural interface, or some imaginary technology can make a direct connection between the human nervous system and a computer. The user interface is to be understood as an intermediary between man and machine, and may include both the hardware and software side of a machine.

Some techniques which attempt to make the interaction more natural include automatic speech recognition or gestures used to send information to a computer. TTS allows you to send audio signal understandable by humans. Data gloves offer a more direct option to the mouse interaction. The HMIs try to immerse users in a virtual reality or augment reality. Interactive tables provide a strong coupling between the direct manipulation by users on a device and feedback.

The following steps are usually applicable in iterative development: develop a user interface, perform testing, and analyzing the results. Iterative development steps are repeated until a practical, user-friendly interface is created. Variety of techniques outlining design technique of human-computer interaction began appearing during the development of this field in the 1980s. Most development methodologies have evolved from models of interaction of users, developers and technical systems. Newer techniques such as cognitive processes of users are treated as predictable and quantifiable.

The main task of human-computer interaction is to improve the quality of interaction, making computers easier to use and responsive to user needs. Long-term goal of human-computer interaction is to develop a system that will reduce the barrier between the human cognitive model and understanding of computer assigned tasks. HMI specialists usually deal with the practical application of development methodologies to real global problems. Their work often revolves around the development of graphic and web interfaces.

Researchers are involved in the development of new methods of design, experimentation with new hardware devices, prototyping new software systems, exploring new paradigms for interaction and the development of theories and models of interaction. In a study of Personal Information Manager (PIM), human-computer interaction makes it an expansive information environment - people can work with various forms of information to understand and effectively influence the desired changes.
