A well-defined sequence of visual stimuli, (e.g. a video file) is presented via a display unit. In parallel, a recorded video sequence is generated, which preferably represents the face of a subject watching the well-defined sequence of visual stimuli. During the presentation of well-defined sequence of visual stimuli, linked data are read out, which indicate timing information relating to the well-defined sequence of visual stimuli. The linked data are registered as metadata associated with the recorded video sequence to produce a synchronized video file, wherein each image is associated to a particular piece of timing information from the linked data. Thus, for example biometric measures derived from the recorded video sequence can be synchronized with the well-defined sequence of visual stimuli. |
