EAO Switch Corporation of Milford, CT USA, a premier global supplier of Human Machine Interface (HMI) Components and Systems, has released a white paper on HMI Systems. This white paper entitled “Human Machine Interface Systems” reviews the importance of good HMI System design as it is critical to the success of products in all market segments. It also encompasses the different factors that should be considered in creating an HMI System, including how to define HMI functionality and identify who the operator will be, selecting the appropriate control technologies (from pushbutton to touchscreen), selecting the appropriate communications technology from hard wiring to bus implementation, identifying and meeting relevant standards, and applying HMI best practices to different applications from medical to industrial.
This paper reviews the importance of a well-designed HMI System, which gives an operator active functions to perform, feedback on the results of the operator’s actions, and information on the automatic functions of the system as well as its performance. An HMI System encompasses all the elements a person will touch, see, hear, or use to perform control functions and receive feedback on those actions. The task of an HMI System is to make the functionality of a technology self-evident to the user; an effective HMI System impacts the acceptance of the entire product.
Also reviewed is the way in which HMI control panel assemblies and subsystems integrate a wide variety of switching, data input, indicator, alarms, communications, and other electromechanical components and technologies. They also incorporate technical, ergonomic, and quality specifications, in compliance with broadly diverse industry-specific, international, safety, and environmental standards. EAO’s HMI Systems fit a variety of markets, including machinery, transportation, medical equipment, manufacturing and process, semiconductor production, and public access.
