OPC Unified Architecture, OPC UA for short, is a standardized and secure solution for machine communication in modern factory automation. The cross-platform standard is based on the specifications of the OPC Foundation and is now supported by all well-known manufacturers of machines and systems, as well as by all common control manufacturers, such as Siemens, Bosch Rexroth, Alan Bradley, Beckhoff, etc. Essentially, OPC UA defines the transmission protocol for process data based on a classic client-server architecture. This protocol allows controllers and devices to communicate with each other, even if they are of different designs or use different operating systems.
Interview With Miriam Bottesch
Miriam Bottesch is working as a User Experience Designer at the User Interface Design GmbH. She has extensive experience in the user-centered design of products from various industries. Miriam Bottesch studied communication design at the University of Design in Schwäbisch Gmünd and graduated with a Bachelor of Arts.
Smart HMI: Hello Miriam, You and your team played a key role in the interaction concept and graphic design of the WebIQ Designer. Meanwhile, your child is running and will be delivered to the first customers. Are you happy?
Miriam: Since 2017, my colleagues and I have been working to bring the WebIQ Designer to the market. I’m very happy, that it is now the time and I’m looking forward to the first feedback from the users.
Choose The Right Gestures
With the advent of multi-touch interaction, a real race has broken out. Companies such as Apple, Microsoft or Google have patented a variety of touch gestures for their mobile smart devices. Some patent applications also contain quite questionable touch gestures and only a small percentage of the patented gestures really found their way into the products.
Make Your Touch Interaction Natural
In natural interaction, we take advantage of the knowledge of what each person brings from their natural environment, such as: the existing knowledge about physics from the everyday experience, etc. In the design of (multi) touch interactions, we play with this knowledge, because natural operation is much more intuitive.
Multitouch has become standard for many industrial HMIs. Smartphones and tablets have shown us the way. Nevertheless, there are some things to consider when you are designing a multitouch HMI. Below we have compiled the most important design recommendations for you.
Know The Used Touch Technology
There are countless different ways in which the touch is detected on the screen. Basically, the following techniques will be differentiated:
