Abstract:The practical essence of urban space determines that diverse sensory experiences cannot be separated from body involvement, especially embodied communication activities. However, technological obscuration has led to the atrophy of embodied communication and the expansion of technological embodiment. Technological embodied communication narrows the subject's sensory activity domain, and sensory perception becomes a technological existence. Visual space has risen while linguistic and other spaces have shrunk, and there have been abnormal phenomena such as the transition from diversity to unification (with visual and auditory senses dominating) in the sensory ecology, as well as sensory experience distortion. Technological normative gaze and structural void are two practical forms of technological obscuration. Technological normative gaze is mainly implemented through three visual metaphoric ways of architecture, surveillance, and image landscape, which weaken and restrict the embodied communication activities of the subject, strengthen the central position of visual sensory perception, weaken sensory experience, and make sensory experience tend towards uniformity; technological structural void further reduces the frequency of embodied communication, and transportation, communication, and image technologies have achieved the elimination of physical distance and abstract removal of distance in space and time compression and de-territorialization, greatly reducing the opportunities for physical contact and compressing the scope of sensory activities. Desituationalization deprives the sensory experience of its authenticity. Therefore, increasing the possibility of body practice, preserving micro-sensory perception and primary socialization in the technological embodiment is the only choice for building a healthy urban space sensory ecology.
