Vestibular_1 (2020) is an immersive audio-visual installation by Albert Barqué-Duran & Marc Marzenit.

Vestibular_1 is an immersive audio-visual installation that invites the audience to wander inside a  vestibular system structure. In specific, the installation induces illusory sensations of self-motion  by temporarily disrupting the audience’s vestibular functioning via specific patterns and  configurations of audio and light stimuli.

Any organism moving through its environment receives a constant stream of sensory signals  about self-motion: optic flow inputs from vision, proprioceptive information about the position of  the body from muscles, joints and tendons, and inputs for acceleration via the vestibular system.  This latter seems particularly important for self-motion (Green & Angelaki, 2010).

Under normal circumstances, the brain optimally combines sensory signals for self-motion, which  are successfully integrated to produce a coherent representation of the organism in the external  environment. However, conflicts between sensory modalities may occur when sensory signals  carry discrepant information. If the vestibular system is altered with conflicting sensory  information, we easily realise that the usual way in which we perceive objects of human  expression, such as visual forms, music, and art, does dramatically change (Gallagher, M.,  Dowsett, R., & Ferrè, E.R., 2019).
