Subject: SCI: Methods of Evaluation for VR Interfaces?
Date: Tue, 4 May 93 09:37 BST



Greetings 

The topic is this, with the emergence that interaction surprise is a
social and situated activity . Evaluation methods have been emerging
such as Suchmann & Trigg interaction Analysis , Activity Theroy as
developed by Bodker, Kuutti, and also Engestrom who are among some of
the people working in this area, Discourse Analysis, Grounded Theory
etc.

What methods have been applied to VR applications to validate them,
any of the above, or has it been mainly heuristic evaluation,
Cognitive walkthroughs?  If any of the above methods have been used
what problems were encountered? (Example, I.A.considers work to be a
situated activity recorded on Video tape to catch the environment,
what happens when you control the environment?)

The methods discussed above have also been aplied to CSCW, what sort
of problems occur when your dealing with multiple perspectives of the
work involved in a VR environment?

I'll try and tabulate any responses  

Thanks for the time
