Guide To Siemens HMI Software

By Marci Glover


Human-computer interaction (HCI) is a multidisciplinary scientific field that deals with the development, evaluation and implementation of interactive computing systems for human use, as well as to study various aspects of its impact. In the field of computer supported collaborative work, emphasis is placed on the ability of systems to support collaborative interaction of a group of people. The system may be based on the Siemens HMI software.

Human-machine interaction (HMI) is a parent field which deals with similar issues but generalizes the interaction between humans and the machine. An important aspect in this field involves the usability of software and hardware. The standard EN ISO 9241 (especially Part 110 and 11) defines which requirements are placed on the usability of software or hardware.

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.

HMI places less emphasis on objectives, procedures and physical activity. The problems tackled by HMI operations are a natural extension of the classical objectives of engineering psychology, except that new problems have a significant cognitive, communication and interactive nature, not previously considered in engineering psychology and helped advance the field in various directions.

Ergonomic studies have also emphasized the relation of working conditions with stress and the visual perception of images. In assessing the current user interface, or developing new interfaces, designers should keep in mind the following principles of development: From the outset, it is necessary to focus on users and tasks. Set the number of users who are required to perform tasks. Iterative design involves determining the number of users, tasks, making empirical measurements.

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.

When designing user interfaces, developers consider the results of cognitive research in areas such as memory and attention. Modern models tend to focus on the ongoing feedback and dialogue between users, developers and engineers endeavor to ensure that the technical system revolve around the needs of users. User-oriented design: the development of user-centric systems is a modern, widely practiced philosophy, the essence of which is that users should be central to the development of any computer system.

From an organic point of view, it is possible to distinguish three types of HMI: The acquisition interfaces: buttons, knobs, joysticks, computer keyboard, MIDI keyboard, remote control, motion sensor, microphone with voice recognition. The combined interfaces: touch screens, multi-touch control feedback. Games and virtual worlds such as Second Life, Everquest or Wolfenstein, where several players or users enjoy overall immersion in a common landscape, provide insight into new relationships that can be implemented through realistic interfaces.
