The International Association of Computer Science in Sport (IACSS), and the predessesor (the WorkingGroup COSISP), have been founded to improve the international cooperation in the field of Computer Science in Sport. Obviously, the internationalization of this discipline is of great importance for the exchange of views, the discussion and presentation of current research results as well as the realization of joint research projects. This has also been become apparent by thirteen successful International Symposiums “Computer Science in Sport ” in Cologne (1997), Vienna (1999), Cardiff (2001), Barcelona (2003), Hvar (2005), Calgary (2007), Canberra (2009), Shanghai (2011), Istanbul (2013), Loughborough (2015), Konstanz (2017), Moscow (2019), Vienna (2022), Hangzhou (2023), and Tokyo (2025).
