People’s optical unconsciousness of the built environment arises from the passive, distracted way in which buildings are often received. As a result, the image of the city becomes fragmented and chaotic. Technology accelerates and destabilises urban experience, encouraging passive consumption rather than active perception. Overstimulated and overwhelmed, individuals struggle to immerse themselves in forming their own coherent understanding of the city’s image.

People’s interpretation and imagination of space have always been shaped by technique and method. As a rapidly developing city attracting substantial investment, London increasingly presents itself as high-tech. Yet this essay argues that emerging technologies encourage the city to be experienced in fragmented and distracted ways, weakening the emotional bond between people and their urban environment. Buildings recede into the backdrop of everyday life, producing the “optical unconscious” described by Benjamin. The essay examines how information technologies and transport systems shape cognition of the city’s image. As these technologies become habitual and inseparable from daily life, they mediate perception, filter attention and structure the ways in which urban images are formed.
