Aév is a tabletop MR experience built around three bodies as spatial anchors: the human body and its location, the table, and the mountain artifact. As you move around the table and swipe, hand tracking reads the gesture and ages the mountain, erosion, growth, and decay standing in for the passage of geological time. The premise: natural processes reveal temporality and cyclicality in a way human systems don't. Human determinism exists in opposition to those natural processes, and stepping into a suspended, observational mode changes how we understand time and space. I founded the interaction paradigm behind the piece and modeled the mountain and its environmental states, working from physical clay and paper prototypes through Blender into the final low-poly builds, along with the surrounding environment. Built for DES 483 with five classmates, including Jax on the Unity swipe detection system and Sabrina leading the philosophy and final video.
