ABSTRACT:
An HMI device for monitoring and control of a technical process, which has a processing module (VE) at least for computer generating dynamic process images (PA1) that have interactive regions (P10–P15). Further, at least one optical transmitter and receiver module (LPE1) is provided, which has a data link (DV1) to the processing module (VE). The module has a projector (LO1) for generating light images (PE) of the dynamic process images (PA1). Further, it has a detector (LD) for spatially detecting pointing actions of an operator (H) to interactive regions (P10–P15) in the light image (PE) of a dynamic process image (PA1).
