Abstract : Outdoor activities provide many benefits, including physical and mental health, skill acquisition and social development. Wearable devices that measure activity data, such as GPS position, speed or heart rate, can potentially help users improve their performance. For this purpose, current systems either present data to the user, or have an expert system evaluate it and provide recommendations. But both these approaches leave out a key player: the expert coach. Expert mentoring has an important and irreplaceable role when it comes to making decisions to improve performance. We argue that in order to effectively improve performance, systems that use wearables to capture data during outdoor activities should provide useful visualizations to experts when these are available.
