Ramesh Jain uploaded interesting presentation to slideshare. The presentation entitled "From health persona to societal health" talks about using personal events based on mobile devices to connect sick people to medical services upon detection of situations. It seems that the area of mobile and personalized healthcare is an emerging area of using events coupled with mobile devices. This can also be a good area for use of non programmer control (e.g. physicians) on situation detection applications. I'll write more on this combination soon.
