This is a proposal I wrote in 2004. It was inspired by a defunct interactive spy game that involved making random phone calls to participants with tips about a vast international conspiracy.
I thought this was a great way to engage health care, public health workers or any emergency response team in a simulation of a real emergency. Typical tabletop exercises are too artificial because they compress time and put the players in close proximity. In reality, public health emergencies sneak up on the participants who must manage their regular activities along with the new ones.
PHIliS could be played in real time with team members performing their normal job functions. Key roles for which there is no participant could be played by a computer-mediated intelligent agent. The system would track all responses and score the participants.
PHILiS would be a development platform for creating any team-based exercise that did not involve face-to-face interaction.
