Human-machine communication

Graphics interface worksheet is a user-friendly way for human-machine communication. It usually consists of three parts (1) Problem specifications The specifications and the required data for the problem to be solved are entered by the user or estimated from the databases. Data are inserted via dialog boxes or buttons for changing some important magnitudes. (2) Problem-type selection The type of problem to be solved is selected via buttons. (3) Results presentation The results are obtained automatically, and are presented in the form of tables or charts. Since these charts are updated automatically, the user has at his disposal all the information needed for sizing, rating, sensitivity analysis, or comparison of alternative solutions.

The term control panel refers to the instrumentation console in a central control room through which process information is communicated to the process worker and via which the worker changes the state of the process. This category includes display elements such as chart recorders, bar indicators, dials, and modem VDU-based systems together with control elements such as buttons, switches, track balls and mice. The control panel is the human-machine interface (see Chapter 2) that has traditionally received the most attention from human factors specialists. 

In general, HTA, IMAS, and CADET fulfill most of the above criteria, hence they can be used together as a framework for carrying out both action and cognitive task analysis. When particular aspects of the human-machine interaction must be examined in greater detail for example, the temporal characteristics of the task or the team communications, certain methods can be selected to provide this information—OSDs in this case. Most TA methods... 

The second section of this chapter deals with the question of how to transform the molecular scenario into a representation for which the eyeball technique can still be used. We shall consider ways in which the molecular scenario can be transformed into one in which human pattern recognition abilities can be successfully used. New instruments of man-machine communication in molecular science will be described and the concept of molecular surfaces will be introduced. These surfaces are envisioned as the interface between different molecules or between a molecule and its solvent. This section also deals with some visualization techniques and the mapping of patterns onto the molecular surfaces it also demonstrates that this type of molecular representation is well suited to the application of the eyeball technique. 

In addition to process simulation, VE systems can be used as mediators for other, generally real, objects. The purpose of presentation of any object is communication. Furthermore, VE can be used as a medium for human-machine interaction. Communication with an umeal object, such as another... 

Human performance is therefore a system design element. The human machine interface (HMI) is particularly important in communicating the status of the SIS to operating and maintenance personnel. 

The enterprise defines the fnnctional and design interfaces to external and/or higher-level and interacting systems, platforms, humans, and/or products in quantitative terms. Mechanical, electrical, thermal, data, communication-procedural, human-machine, and other interactions are included. 

We have developed a prototype collaborative virtual environment, which actively supports human-human communication in addition to human-machine conununi-cation, for molecular electronic structure theory. We submit that key elements of e-science, such as collaborative virtual environments, will evolve most rapidly and deliver a functionality required by practicing scientists if they are developed as part of a research project in the target discipline. This is the approach that we have followed in this work. We have developed a collaborative virtual environment for molecular electronic structure theory whilst undertaking research into aspects of the Brillouin-Wigner theory for many-body systems. Others working in molecular physics and quantum chemistry may find this a usefiil starting point for the development of improved environments. Such environments wiU undoubtedly evolve with time as higher bandwidths and new tools become available. 

However, there are still not enough answers regarding the communication of decision aid systems and operators. There are indeed a number of compatibility problems between the human operator s mental steps and the decision aid tool s reasoning process. Our approach consists then in this workshop, in looking for new solutions in this field, and in considering to which extent the new hypermedia technologies can contribute to the man-machine communication in the industrial complex processes. 

Computerized operator communication stations replace much of the conventional panel instrumentation in the control room. A number of human-machine communicahon stations, each essentially comprising a keyboard and color cathode ray tube monitor, are located on the main control room panels. The displays provided on the monitors include...

Human—machine interface (HMI) This relates to the operator s action and communication with the process. Correct operational aspects and the operator s failure to react must be considered in this subsystem. In addition to this, the subsystem needs to interface for engineering and programming changes.
