Panels come with multi-touch: People prefer to work with their hands rather than type with their fingers

摘要

THE potential for designing HMI with GUI and SCADA terminals in factories has evolved significantly in the past few years. This potential is being driven by the increasing availability of multi-touch displays suitable for industrial use, as used in tablet PCs, for example. Completely new forms of user interaction have emerged, like turning screen content using two fingers, zooming into content by spreading fingers or scrolling by simply swiping. It is even possible to implement two hand operation in order to facilitate switching motors on or off, and even the mechanical dead man's switch could be replaced. But whatever concrete solution needs to be created, the most convincing form of operation is one which is simply carried out by hands. It is only natural for people to want to work with their hands rather than type with their ringers. But even typing is simpler with multi-touch displays. In comparison to one-finger operation the shift-key can be activated.
