Embodiment Construction

[0092] Figure l schematically shows a component or system on a graphical user interface (GUI) associated with the input 10 for safely, which has a computer, the computer to generate a pixel format of the digital image data. 3 for display image data is conveyed through the appropriate lines image data to the COTS display 2, a computer such as a TFT screen. In considering any COTS computer, such as a computer as an expression of the desktop PC 1, the following graphic PC 1 for short. PC 1 is considered to be unsafe or insecure or unsafe technically signal in the sense of security technology in the sense of safety requirements. Furthermore, in order to PC1 any, in relation to the desired using the GUI on the display 2 can be expressed in different, if necessary in relation to the context or the display mode is programmed or programmed mask (see FIG3A-3C). 10 is part of the system in FIG l is an input device for the GUI operation, that is, opposite, continuous and indirect pointing de...

Abstract

The invention relates to security-relevant input on a graphical user interface (GUI). In this instance, a computer (1) generates image data that are transmitted to a display (2) via an image data line (3). The user interface has at least one graphical operator control element (6) that is selectable by input device (4). Furthermore, a monitoring unit (21) is connected to the image data line (3) and reads image data for a security function. According to the invention, the monitoring unit (21) is supplied with input information from the input device (4), and the monitoring unit (21) is connected to a confirmation apparatus (14) via a secure signal path (11B) for the purpose of user confirmation. According to the invention, there is moreover provision for the monitoring unit (21) to ensure and / or check whether a detected selection (5) of the operator control element (6) is represented correctly, and, in the event of a user confirmation for a represented selection of the operator control element (6), to enable or trigger an associated security-relevant operator control command, in particular via a secure signal path (HD). This allows secure input even with non-security-certifiable input devices, in particular relative and / or indirect pointer devices, such as e.g. a commercially available computer mouse. Furthermore, preferred architectures for monitoring units are proposed that are suitable for the proposed input method in particular.

Description

Technical field [0001] The present invention relates generally to graphical user interface (GUI), in their application security in the sense of risk or operational security (English as safety) in the decisive. Background technique [0002] The present invention particularly relates to the following user interface, or for example, determined on the console or a control device for operating industrial equipment system, the reactor in such devices or adjustment mechanism for a railway art in the user interface operation or input is crucial for safety or critical. We must ensure that the applications, or the input information is detected accurately corresponding to the selected or the selection performed by an operator. [0003] Information as a pure expression of computer graphics has been error prone. Thus, for example, any error may produce the individual components of the computer graphics appear, for example due to a failure of the microprocessor, the graphics processor, in sepa...
