Chapter 9 deals with the ethics associated with Virtual Humans - both in terms of how we use them, and the issues involved when carrying out research with them. Having run a couple of covert Turing Tests where deception was very much part of the experiment we are acutely aware of some of the latter issues, and even some of our early work on virtual personas is already bringing a variety of ethical issues to the fore.
We'll post useful models and additional analysis here.
