Applying Wearable Sensors to Avalanche Rescue: First Experiences with a Novel Avalanche Beacon

Abstract: We present a novel approach to enhance avalanche companion rescue using wearable sensing technologies. The time to find and extricate victims is most crucial: once buried by an avalanche, survival chances drop dramatically already after the first 15 minutes. Current technology offers only information on the location of a single victim. , however Sstatistics show that in many case there are multip le victims. In our research we address this issue and also investigate how the use of wearable sensors can further enhance such devic es. We report on experiments using sensors to measure vital signs and environmental conditions and their suitability for avalanche re scue. Visualization for this type of application is addressed and two design sketches, both visualizing multiple victims and urgency, are presented. The architecture of current devices is extended by components to integrate these additional functions. We develop ed areport on prototypical implementation of an avalanche beacon supporting multiple victims and visualization of vital signs. This prot otype was used for further experiments and offered a basis for participatory evaluation with practitioners in the field. A short over view thereof is presented.
