Remnance of Form

Interactive Narratives with Augmented Shadows

Sang-won Leigh, Ann Paradiso and Asta Roseway

Remnance of Form is an interactive art installation comprising a series of vignettes designed to challenge our notion of reality through the manipulation of light and shadow. By fusing light, projection, and motion technologies, the shadow can now detach itself from its former role. This creates a new narrative that blurs the border between what's real and what's not.

The installation dynamically modulates and distorts the relationship between simple, mundane objects and their shadows. Through ambient augmentation of the shadows happening in the periphery of viewer's attention, we try to shift and extend the perceived nature of the objects. Through the presented vignettes, we examine the fundamental human perception of reality on one level while fostering a deeper connection between viewer and the object/shadow relationship.
