In the event-based multimedia I met Pil Ho Kim from University of Trento. He wears a camera that takes picture every minute from his life as long as other indicators such as temperature and creates his personal detailed log. This is part of his study on human behavior, He posted a presentation given at the ACM multimedia conference on Slideshare (it seems that he borrowed one slide from my presentation) entitled: "how to monitor human behavior". He is using ESPER for doing event processing, based on the multimedia events collected. This is a good example of using complementary technologies along with event processing.
