Magyar / English     Langh Róbert     Retroscope (computer installation) 2003 Changing the position of the mobile office chair the user enters virtual zones of the exhibition hall, and activates multimedial videos assigned to them. The separate video pieces can be rolled back and forward by adjusting the chair, as the playback head is connected with it's position. The sub-matrices of the zones are in direct connection with the playing time, and travelling through the table-like virtual layouts we can jump to different places of the videos nonlinearly. The chair's built-in display is getting the audio-visual program through a radio transmitter from the computer, which monitors the position of the chair by a video camera on the top. The position-analysis depends on the camera's brightest point; that is the chair's display itself. As the modell can be used for different purposes, in this case it runs an archive of private videos, illustrating the method. The CD-rom collection contains a system of the videos made between 1989 and '95, and can be run as a separate multimedia application. The dynamic interface is an infinite collage of video masks, slipping into directions of the user's way.   The images of the installation were taken at the "AURA" media-art exhibition, based on the essay "The Work of Art in the Age of Mechanical Reproduction" of Walter Benjamin, curated by Miklos Peternak and Nikolett Eross from the C3 Foudation.
