Abstract: The invention relates to a method for testing quality of an object in a real environment using a camera, an optical display device, and a processing apparatus, the method including the following steps: defining a test geometry and a reference geometry in a computer-assisted data mode; defining a test pose, in which the camera should be placed by the user as target positioning for a quality test to be carried out of the object to be tested; and visualizing the test pose on the optical display device. In a second phase, at least one image of the real environment is captured by the camera, the pose of which camera is in a range that includes the test pose, and the test geometry and the reference geometry in the image are tracked. Furthermore, a pose of the tracked test geometry in relation to the reference geometry and at least one parameter are determined on the basis of how the pose of the tracked test geometry is in relation to a target pose of the test geometry defined within the data model.

Abstract: A dishwasher, in particular a household dishwasher, includes a dishwasher cavity for cleaning dishes, glasses, cutlery or similar wash items. The dishwasher cavity has a plurality of walls that delimit it, with at least one of the walls including a through-hole. A flat lighting unit is configured for placement in the through-hole such as to be pressed by a mechanical force application element against edge regions surrounding the through-hole.
