User acceptance of observation tools for game analysis highly depends on the quality of respective user interfaces. The paper presents three customized, noncommercial tools which were developed for the German national beach volleyball teams. BeachScouter enables coaches to capture live game data via touch screen. BeachTracker uses methods from computer vision in order to track the players and the ball automatically. Additionally, BeachViewer is designed for the quantitative analysis using this positional data, subsequently structuring video footage for further qualitative analysis. Based on the experiences while developing these tools, five design principles for game analysis software are suggested, (a) separating data collection and analysis, (b), minimizing input load during data collection, (c), provision of at least two levels of analysis, (d) using computer vision to reduce the amount of manual inputs, (e) orientation on specific questions of coaches and players.
