Environment Scale Fabrication: Replicating Outdoor Climbing Experiences

ACM CHI 2017, Denver Colorado Despite rapid advances in 3D printing, fabricating large, durable and robust artifacts is impractical with current technology. We focus on a particularly challenging environmentscale artifact: rock climbing routes. We propose a prototype fabrication method to replicate part of an outdoor climbing route and enable the same sensorimotor experience in an indoor gym. We start with 3D reconstruction of the rock wall using multiview stereo and use reference videos of a climber in
