METHOD FOR THE SECURE AND INTENTIONAL ACTIVATION OF FUNCTIONS AND/OR MOVEMENTS OF CONTROLLABLE INDUSTRIAL EQUIPMENT

摘要

The invention relates to methods and devices which allow the secure, intentional and error-free initiation of different, directly executable industrial functions of machines or similar using a comparatively large-area, touch-sensitive entry means, in particular of the touch-screen type. A plurality of operating elements or selection fields is depicted on the entry means and the operator is able to find and actuate the operating elements without visual aid or control. The core part of the invention relates to the use of such touch-sensitive entry means of the capacitive touch-screen type, according to which 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 said field in a first step and makes an entry by means of a characteristic touch gesture in a second step. This allows the control system to differentiate accidental contact, such as an unsighted feeling of an identified operating element, from a deliberate operating action, and thus to reliably prevent unintentional operating actions.
