Like many trends, multi-touch started in the commercial world and migrated to industrial automation. The driving force for this trend is user demand for the speed, power and flexibility of multi-touch in their plant floor operator interface applications. After exposure to the advantages of multi-touch through smartphones and tables, users will no longer accept the older, inferior single-touch technology. Suppliers are responding by incorporating multi-touch technology into their products. Newer versions of Windows have built-in multi-touch support, as do most modern touchscreens. Many SCADA and PC-based HMI software programs have native multi-touch support, making it easy for users to design their applications to take full advantage of capabilities such as zoom, pinch, expand, swipe and pan — along with multi-finger touch capability.
