Abstract
A method for non-invasive video oculographic measurement of eye movements as diagnostic support for (early) detection of neuropsychiatric diseases, using an indicator for a visual stimulus and a camera for video recording. A position of the camera is kept constant in relation to the display and a face of a test person is continuously recorded, at least in parts. A recognition algorithm is started which creates an eye template in which an absolute position of the eye and a pupil of the eye are continuously recorded in the image. Furthermore, a reference range, especially around the eye, is defined and, after selecting a predefined measurement paradigm of the pupil are continuously recorded and analyzed at the end of the stimulus.
