This paper presents game information analysis by utilizing a digital scorebook system, as the first tool for curling informatics, which supports coaches and players in realizing smart tactics and strategies in the sport of curling. Our research project, called “Curling Informatics,” aims to develop an environment to support curling strategies and tactics by realizing methods to record game information, perform analysis, and provide visualization and sharing of the information.We found a significant correlation between the differences in shot accuracies and scores from game information collected by our digital scorebook system for more than 200 games played by the Japanese national class. The results suggest that the difference in shot accuracies is related to the difference in game scores. This is valuable new knowledge to support strategic/tactical planning in curling games. However, the correlation for games involving world-class teams becomes weaker than for the Japanese national class because there is scarcely any difference in shot accuracies.

Japanese curling teams have been recently preparing for Pyeongchang Winter Olympics in 2018. In curling, there are three factors influencing game performance: physical factor, human factor, and strategic/tactical factor. The strategic/tactical factor is considered as the most important at top level. To support the strategic/tactical factor, we proposed the concept of Curling Informatics. As the first step of Curling Informatics we developed a digital scorebook iCE for digital collection of game information, storing it in a database and performing further analysis to improve player performance. In this article, we further contribute to this project by analyzing game information of world national top level teams. We have previously confirmed that correlation between shot accuracy and game score could differ with the team level or position. We also found out that selected tactics and psychological pressure on opponent team has impact on game result. However, previous analyses disregarded the order of teams in play, which could result in confusion of strategic tendencies or play characteristics. In this paper, we carried out analysis of correlations of shot scores considering whether the teams started as the first or the second. We did this to specify the process of how the team strategy/tactics influences game results.
