The Blind Men and the Elephant Revisited

The construction of embodied conversational agents is an ambitious, complex, and essentially interdisciplinary process. This is inevitable given the depth, sophistication, and many modalities of the products we seek to create. Other chapters in this book address methods for evaluating ECAs as artefacts or according to their usability. In this chapter, we offer a complementary perspective: grounding the evaluation of ECAs in the context of the different disciplines that have merged to create the research community constructing them.
