Anything that can be seen on a screen could be seen anywhere. If a screen is placed between the real object and the visitor – be it enhanced reality or an iPhone – it transforms the real object into a screen experience, and has no place in an exhibition. Videos, which generally have beginnings, middles and ends, can statistically be relied upon to be somewhere in the middle when a visitor arrives, meaning a wait until the video restarts. The practice of waiting for videos to begin contradicts the usual ways in which visitors ‘browse’ an exhibition space. Except in carefully studied circumstances, narrative videos should not be used in exhibitions. Interactive media, which can respond to individual visitors, overcome many of these difficulties, but should be carefully used to enhance the understanding of the artworks and not detract from the experience of the real object.
