We present a study of people’s use of positional information as part\ud of a collaborative location-based game. The game exploits self-reported positioning\ud in which mobile players manually reveal their positions to remote players\ud by manipulating electronic maps. Analysis of players’ movements, position\ud reports and communications, drawing on video data, system logs and player\ud feedback, highlights some of the ways in which humans generate, communicate\ud and interpret position reports. It appears that remote participants are largely untroubled\ud by the relatively high positional error associated with self reports. Our\ud analysis suggests that this may because mobile players declare themselves to be\ud in plausible locations such as at common landmarks, ahead of themselves on\ud their current trajectory (stating their intent) or behind themselves (confirming\ud previously visited locations). These observations raise new requirements for the\ud future development of automated positioning systems and also suggest that selfreported\ud positioning may be a useful fallback when automated systems are unavailable\ud or too unreliable
