The theoretical ideas underlying actor-lab are derived from the event-driven, message-passing computer languages that began with the actor based languages devised by Hewit. Practical inspiration was provided by HyperCard and to some extent by Lab View.
The first version was developed in HyperCard (in 1992) but the problems associated with having to input scripts via the HyperCard editor meant that it was only useable with year 7 children. The current graphic interface avoids any problems with syntax errors, and was developed using Macro Media Director. (More details can be found in the User Manual, see the 'downloads' page)
