Abstract:
1. HMI device for monitoring and control of a technical process, comprising: a) a processing module, at least for computer-generating dynamic process images that have interactive regions, b) at least one optical transmitter and receiver module that has a data link to the processing module, b1) a projection means for generating light images of at least one of the dynamic process images, b2) a detection means for spatially detecting pointing actions of an operator to at least one of the interactive regions in the light image of the at least one dynamic process image, and c) a support plate providing a projection area for the light image of the at least one dynamic process image, wherein the at least one optical transmitter and receiver module is mounted to the support plate and the processing module is mounted behind the support plate, and wherein the support plate has edge lengths longer than respective edge lengths of the processing module, wherein the processing module is configured to insert into a mounting opening in a mounting surface, and wherein the support plate completely covers the mounting opening.
