Backcountry skiing: reaching new heights with connected skis

03. Thanks to a small screen on their skis, backcountry skiers can see various data recorded by sensors as they ski. The length and number of turns going up, their cadence and even the symmetry of their steps appear on the device. It was developed by an EPFL spin-off that teamed up with a local equipment manufacturer. The device, which attaches directly to the skis, is small and light and loaded with sensors. It is equipped with a screen that switches between showing various performance stats and data on the surrounding environment. Skiers working their way up the slope see in real time the length of their turns going up, their cadence, the symmetry of their steps, the temperature of the snow, and more.
