Devices recording position and heartbeat rate allow raw data acquisition for this analysis, but existing software functionality is limited. The paper addresses the collection of interaction requirements for the application to develop that followed a user centred approach with role-playing, interviews, focus groups, scenarios and usability experiments with users involved in outdoor sports practice and competition. The work assessed issues relating to data acquisition, correction, analysis and presentation as well as data persistency and user profiles. A comprehensive set of interaction requirements are then identified and analyzed. Candidate solutions currently being implemented and tested in a full-scale prototype are presented.Interactiondesignsportsperformancedata analysisdata acquisitionmobile computing10.2312/pt.2010115839-46
