I presented this paper at the Presence 2002 conference in Porto, Portugal. Bits were conveyed in Playing With The Past, but the initial ideas have been taken up and applied by others beyond my original concerns. A new or more extensive theory is required, especially with the development of augmented and mixed reality, biosensors, camera tracking, and new Head Mounted Displays.

But the new article will probably not appear for about a year, I am not certain where it should or could be published!

Anyway, the 2002 paper is attached.
