Objects intended as elements in interior spaces generally do a great job of meeting the standard criteria of form and function, but they can do more. By becoming something other than what they normally are, common elements can change a viewer's response to the space itself. This subtle but unexpected expression by an object impacts the viewer on many levels, heightening awareness and changing the viewer's cognitive interpretation of the space itself. This document examines the activation of space through objects capable of responding to a viewer's presence, using as a focus a light fixture that uses motion sensors to trigger sequential lighting responses in different locations, which move from low to high activity states. This object and its changing states are designed to engage viewers and provoke interaction. Such a reaction fundamentally reshapes the space the light fixture inhabits by actively transforming it into a playfully experiential environment.
