ClimbAR: Collaborative Augmented Reality for Climbing Applications

In this work we present ClimbAR an open-source, collaborative, real-time, augmented reality application for the Hololens 2 that al-lows boulderers to set climbing holds virtually to better understand and plan routes. We performed two preliminary studies a quanti-tative study that assessed the system's rotational and translational alignment accuracy and a qualitative study that used surveys and voluntary participation to evaluate the usefulness and enjoyment of the system.
