The system has a recording component, a visualization component, and produced log files as the interchange. A lab study uses 10 players to generate data and 16 analysts to compare Echo versus raw video, finding lower cognitive load, significantly less frustration, and higher efficiency for task-driven analysis of racing sessions.
