8 embedded world the official guide 2021 Trends Gutschein kostenfreies Messeticket HMI and user experience Humancentric interfaces for Embedded Systems As the range of functions of modern devices and systems increases so do the demands on humanmachine interfaces Despite greater complexity modern user interfaces must be easy to operate In this interview Prof Robert Oshana from NXP Semiconductors proposes putting the human at the focus of the humanmachine interface ▷ Since industrialization humans as users have been forced to adapt to machines Prof Oshana you are now proposing to put the user at the center of the humanmachine interface What does that mean in concrete terms? ▶ Prof Rob Oshana The description …forced to adapt to machines is exactly what happened in the early days of user interface design and a shining example of this was the article How the dumb design of a World War 2 plane led to the Macintosh by Cliff Kuang 1 Understanding basic human factors and then designing to support these human factors is essential to successful user interface design Key design concepts such as minimizing a users memory load mapping to the users mental model and adhering to design principles are just a few examples of putting the user at the center of humanmachine interaction This is becoming increasingly important as user interfaces become essential components of wearables automobiles medical and manufacturing Forester Research has estimated that on average every U Sdollar invested in the user experience brings 100 U Sdollars in return ▷ What are the distinguishing features of humancentric interfaces? ▶ Prof Oshana There are three distinguishing features of humancentric interfaces The interface is designed properly as a sensory processor in the sense that it fits within human limits The interface is an interpreter and predictor in the sense that it fits within the knowledge constraints of the user and The interface is an actor in the environment in the sense that it fits within the proper task and social context Image PopTika | Shutterstock Prof Robert Oshana NXP Semiconductors Rob Oshana is Vice President of Software R&Dfor the Edge Processing business line at NXP He serves on multiple industry advisory boards and is a recognized international speaker Prof Oshana has published numerous books and articles on software engineering and embedded systems He is also an adjunct professor at Southern Methodist University and is a Senior Member of IEEE robert oshana@nxp com Bild NXP
