Abstract
Method, device and system for capturing and processing viewing data, which viewing data relates to the viewing behavior of users when viewing video data. Data about lines of sight of a user relative to the viewed video data are determined by projecting video data directly on the retina of the user and current eye positions of the user being thereby determined, which are transmitted by a telecommunications network to a central unit for further processing. In the further processing current eye positions are compared with predefined values, and predefined actions are triggered on the basis of the result of this comparison and/or the viewing data being stored in the central unit, and, for example later, being evaluated statistically.
