Dear XMCA community

I would like to take this opportunity to direct our distributed cognition to
challenges I encountered using CHAT (in particular Engeström's triangle) to
represent collaborative activities graphically; and evaluate the alternative
representation I developed while wrestling with these problems.

In an attempt to get these thoughts "out of my head", so I can share them
with you, I created "AltrepCHATsys.pdf". This is an interactive electronic
document and includes animations (Acrobat Reader 6 required) and a 3D model
(Acrobat Reader 7 required) in an attempt to capture the dynamics and
complexity of collaborative activities. Older PDF Readers will also work;
however, the interactive elements will be static.

I would greatly appreciate it if you could have a look at this attached
document (when you have some time) and share your thoughts regarding these

Thank you
Hendranus Vermeulen
