Virtual game show host — Dr. Chestr

This paper describes the design, implementation and evaluation of an interactive virtual human Dr. Chestr: Computerized Host Encouraging Students to Review. Game show hosts exert a unique personality that becomes the trademark of their respective game shows. Our aim is to create virtual humans that can interact naturally and spontaneously using speech, emotions and gesture. Dr. Chestr is our virtual game show host that exhibits a personality designed to increase user engagement. Dr. Chestr is designed to test users with questions about the C++ programming language and allows the user to communicate using the most natural form of interaction, speech. We present the architecture and user evaluations of the Dr. Chestr Game Show.
