10 years ago the AutoAuditorium™ System was introduced as a fully automatic alternative to manually created video of auditorium and classroom presentations. It combines a target-free, initialization-free Tracking Camera subsystem with a Slide Camera, additional cameras, and an automatic Director subsystem that runs a video mixer. Together they produce a television program of a presentation in real time.
This paper describes the system as high-level concepts and their implementation in hardware. It then recounts how the system has been used by several customers.
