Abstract: Methods and devices allow the secure, intentional and error-free initiation of different and directly executable industrial functions of machines or similar using a comparatively large-area touch-sensitive entry device, in particular of the touchscreen type. Operating elements or selection fields are depicted on the entry device and the operator is able to find and actuate the operating elements without visual aid or control. Using such touch-sensitive entry device of the capacitive touchscreen type, the provided operating elements or selection fields are identified by applied haptically perceptible markings. In addition, in order to initiate an operating element or an industrial function that is associated with a selection field, the operator selects the field in a first step and makes an entry by a characteristic touch gesture in a second step.
