The Embedded Opportunity AroundHuman-Machine InterfaceA Human-Machine Interface, or HMI, is defined as the userinterface that connects a person to a machine, system or device.Although that may seem simplistic, modern HMIs are everywhereand help users access useful information in a simple to useand understandable format.As HMIs proliferate and become ever more complex, this guide aimsto identify how and where the opportunity lies for manufacturers ofembedded technology.Although HMI is the most commonly used term, a number of otherabbreviations can also be used, such as Operator Interface Terminal(OIT), Local Operator Interface (LOI) or Man-Machine Interface (MMI).HMI and Graphical User Interface (GUI) are terms which are sometimesused interchangeably, but which have different meanings. GUIs areoften leveraged within HMIs for visualization capabilities.avnet.com/embedded Email: avnetembedded@avnet.comAvnet Confidential Avnet, Inc.

What’s New in HMI?As businesses change and develop, the need for information has led to an explosionin the amount of data being generated, captured and stored. With hardware andsoftware developments, sophisticated HMIs are becoming more common as thedemands placed on them are diverse and varied. Better displays, richer graphics,and a range of different devices such as touch screen and mobile means there ismore opportunity for innovation in HMIs than ever before. For example:High Performance HMIs – have beendeveloped to ensure fast and accuratecommunication of essential data. Simpleand clean, these systems are built tooptimise the user experience and showonly limited or necessary data, at speed,allowing users to interpret and respondquickly.Touch screens and mobile devices –instead of buttons and switches, the riseof smartphones has led to a demandfor a more typical consumer-typeinterface, familiar to all. Mobile devicesused at network edges and in industrialand SCADA type applications allowoperators to simply tap the screen toaccess controls. This can be especiallyuseful in more remote applications oracross networks.Remote monitoring and Edgecomputing – allow a number ofbenefits, the most obvious being theneed to access data without visiting aphysical location. As computing extendsaway from the datacentre, remotemonitoring becomes more important.Edge devices allow operators to accessdata and visualization from the field andthrough the cloud alike.Augmented Reality and VirtualReality – as software continues tobecome more sophisticated, withgreater capabilities to manage andaugment data with machine learningand artificial intelligence, AR and VRbecome useful tools in data modellingand display. HMIs become moreimportant in being able to access andshow this data and in themselves willcontinue to develop in sophisticationas the access point into the network.IN THIS REPORT WE WILL FOCUS ON 3 KEY AREAS OF HMI:- Display and the development of touch,- Graphical User Interface (GUI)- How HMIs can be used specifically in manufacturing.avnet.com/embedded Email: avnetembedded@avnet.comAvnet Confidential Avnet, Inc.
