Abstract
Digital doppelgangers are virtual humans that highly resemble the real self but behave independently. An emerging computer animation technology makes the creation of digital doppelgangers an accessible reality. This allows researchers in pedagogical agents to explore previously unexplorable research questions, such as how does increasing the similarity in appearance between the agent and the student impact learning. This paper discusses the design and evaluation of a digital doppelganger as a virtual listener in a learning-by-explaining paradigm. Results offer insight into the promise and limitation of this novel technology.
