A depth information detection device detects an item of depth information relating to a user's head, including a distance from the user's head to the device. On the basis of this depth information and, if applicable, additional information such as images, an evaluation device determines the desired parameters for fitting the spectacles, such as centering parameters.

A method is provided for the user-specific calibration of a display apparatus, wearable on the head of a user, for an augmented presentation, wherein A), in a basic calibration step, the position of the at least one eye is ascertained relative to the display apparatus in all three spatial directions in the state where the display apparatus is worn on the head of the user and said position is saved in the display apparatus as adjustment data in such a way that an image generating module of the display apparatus generates the image taking account of the adjustment data.

An apparatus () for determining centering data for eyeglasses () comprises a fixation device () and a recording unit () that can be triggered by a computer, records electronic images, and is disposed behind a divider element (). The fixation device () produces at least one speckle pattern. The speckles can be superposed by different patterns, for example, a cross shape. The invention further relates to a method for determining centering data. The inventive method and apparatus allow to measure for test persons having the most different acuity of vision the relative centering data from a short distance while maintaining their usual posture.
