Abstract: In this paper, we aim to develop an AR system which supports spectators who are watching a sports game using smartphones in a spectators ’ stand. The final goal of this system is that a spectator can watch information of players through a smartphone and share experiences with other spectators. For this goal, we propose a system which consists of smartphones and fixed cameras. Fixed cameras are set to cover the whole sports field and used to analyze players. Smartphones held by spectators are used to estimate positions where they are looking on the sports field. We built an AR system which makes annotation of players ’ information onto a smartphone image. And we evaluated the accuracy and the processing time of our system and revealed its practicality. 1
