Inspired by microorganisms called extremophiles that live on the edge of habitability, in some of Earth’s most inhospitable environments, Hinterlands is a mixed reality headset experience on the speculative futures of human evolution. By moving through the space, you will explore our entanglement with the natural and digital world and our possibilities for surviving, evolving and becoming. Hinterlands has been developed over the past three months as Rebecca’s final MA project in Virtual and Extended Realities at UWE Bristol. The team explored live motion capture streamed to headset to move an AR non-humanoid entity in Mixed Reality using passthrough mode to three untethered Pico 4's. Wearing a headset you will see both the world around you and an augmented reality layer. For the final scene, the dancers' movements affect the augmented layers through the use of a motion capture suit. Three dancers and three audience members navigate this space through a structured improvisation score. What has been created is a three-part experience over 25 minutes.
