Livia Schmid – Trail Sync
with Pauline Saglio, Christophe Guignard, Alain Bellet, Laura Nieder, Gaël Hugo, Lara Défayes
In remote alpine regions, access to reliable information — such as trail conditions or weather alerts — becomes difficult in the absence of network coverage. Trail Sync addresses this challenge through a participatory and decentralized approach: local information boxes, integrated into hiking infrastructure, are passively updated by hikers using an offline mobile application. Each person passing near a box synchronizes contextual data, leaving a digital trace that benefits those who follow. Reinforcing existing signage without increasing technological dependency, the system is rooted in the mountain values of collective responsibility and solidarity.
