Christoph Albert Johns presented our paper “Heads Up!: Towards In Situ Photogrammetry Annotations and Augmented Reality Visualizations for Guided Backcountry Skiing”, at the AlpCHI conference which took place from March 1-5, 2026 in Ascona, Switzerland.
AlpCHI is the inaugural Human-Computer Interaction (HCI) conference of the Alpine region which brings together researchers, industry professionals, and academics to exchange ideas and explore new developments in HCI.
The study focuses on backcountry skiing where groups of skiers navigate challenging terrain outside of managed slopes. This activity requires careful monitoring of weather conditions and effective communication about potential hazards. The research aims to support this communication by providing backcountry guides with a set of in situ spatial annotation tools, allowing them to mark risks and recommend appropriate speeds on site.
