The device comprises a housing in which operating elements are arranged for detecting and processing data and/or reproducing the data in an imaged manner, and a combiner panel arranged on the housing. The housing is elongated and has a curved geometry such that the housing can be arranged substantially in the front region of the helmet above the eye(s) of the user, and the combiner panel can be positioned in front of the eye of the user.
