Touchscreen introduction
Your machine has been equipped with a “Human Machine Interface” or HMI or -more popular
called-: A touch screen.
If you are familiar with touch screen operation, found nowadays on modern cell phones,
navigation systems, informational displays etc. you may want to skip this section. If however,
this is the first time you are using a touch screen, please keep in mind that in contradiction with
older fashioned operating panels utilizing mechanical buttons, lamps and displays, both the
displays and images on a touch screen can be interactive too, meaning they will react on a
touch by your finger. The interface on the touch screen is optimized for ergonomic operation. In
practice this means that all objects are positioned and sized such, that they can be touched
easily with your finger without the need for a stylus or precise positioning. A soft tipped stylus
can be used if preferred, but is normally not required for proper operation.
Touching objects on a touch screen can be compared with a mouse-click on a computer screen.
Based on the shown graphical user interface and your finger’s position on the screen, the
system can determine what action it should take when an object is touched.
To prevent accidental, unwanted actions some objects may require a prolonged
touch, meaning you should keep your fingers pressed longer on a certain object
(like a button or display) to invoke the required action.
