How can light art manipulate the visual perception of space?

Abstract

Transitioning from a field of engineering to a medium for more artistic expressions, lighting has changed from strictly functional lightboxes to elaborate light-based designs and installations. Both artists and architects have used light as a medium to manipulate visual perception and impressions. This paper explores the interaction between light, visual perceptions, and space. Through a case study of artworks that experiment with light, space, and visual perceptions, it discusses how light art can impact perceptions by the way it illuminates spaces. The findings demonstrate the impressions and perceptions created by light art and coloured light as an artistic material. The aesthetic application of light can remove boundaries and define a space in a different way. Although lighting installations are primarily part of architecture and interior design, this article proposes how light can be applied in design by manipulating the visual perception of the design on users.
