Dis-Armor project challenges and changes understanding of observer. Jonathan Crary argues that, “Though obviously one who sees, an observer is more importantly the one who sees, an observer is more importantly one who sees within prescribed set of possibilities, one who is embedded in a system of conventions and limitations.”(Crary 6) The observer perceives everything through his vision. Crary goes even further to explore all the circumstances that influence and shape this particular vision of the observer in a particular way. He contends that numerous machines invented throughout the centuries aimed to structure human vision with the framework of particular set rules, “These apparatuses are the outcome of a complex remaking of the individual as observer into something calculable and regularizable and of human vision into something into something measureable and thus exchangeable.”(Crary 17)
