The variables of spatial presence: a parametric model
(Edições Universitárias Lusófonas, 2019) Sá, Adriana; Tanaka, Atau; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
The term ‘spatial presence’ refers to the feeling of presence in a mediated space. This subjective experience has been discussed in media theory, sound art, film and performance. It depends on multiple variables, or parameters. This paper presents a parametric model that can be used to analyze those variables and their relationships. It exposes methods to assess interaction, characteristics of sound and image, audio-visual relationship and physical setup. It also exposes methods to assess how these variables intertwine in perceptual experience. The model draws from perception science, interaction design, music and audio-visual theory. It is applicable to the broad diversity of aesthetical options and technical platforms, facilitating the analysis of spatial presence in any performance. One can also discard part of the parameters so as to analyze installations, sound art and film. Keywords: Parametric model, spatial presence, attention, semantics, performance
