JND (just noticeable difference)

JND (just noticeable difference) #1: Semblance
Interactive Installation

JND is a new series of multimedia installations that explores the concept of just noticeable difference.

The first project, Semblance, is an interactive installation exploring the phenomenon of cross modal perception – the ways in which one sense impression affects our perception of another sense. The installation comprises a series of modular, portable “pods,” each of which is installed with devices that produce subtle levels of tactile, auditory, visual and olfactory feedback for the visitors, including a floor of vibrotactile actuators that participants lie on, peripheral levels of light, scent and audio sources which generating frequencies on the thresholds of seeing, hearing and smelling.
