I ran across this call for paper: Pervasive Computing in Sports. Submission Deadline: 14 February 2005.

IEEE Pervasive Computing invites articles relating to the use of pervasive computing in sports to enhance the sport (or game) and/or experiences for players, spectators, and/or judges. We hope to span a wide range of sports including single-player, multi-player, and large team sports as well as activities ranging from track and field to indoor team sports to racing. We especially welcome papers that bridge multiple aspects of a system, report on the challenges of integration and deployment, and report on usage experience
