ABSTRACT
In this work, we developed virtual humans (VH) designed to persuade users. We introduce the notion of distinctiveness of topics and define two kinds of persuasion strategies: "objective persuasion", which aims to persuade with only objective sentences and no expression, and "subjective persuasion", which aims to persuade with only subjective sentences and smiles and gestures. We performed experiments in which a VH recommended trips under two conditions. In condition 1, the VH recommended a topic that she preferred using subjective persuasion and another topic using objective persuasion. In condition 2, she recommended a topic that she preferred using objective persuasion and another topic using subjective persuasion. Results showed the VH in condition 1 increased the buying motivation of participants.

The effect of subjective speech on product recommendation virtual agent
IUI '19 Companion: Companion Proceedings of the 24th International Conference on Intelligent User InterfacesIn this paper, we verify the effect of a VH's objective and subjective speech. We hypothesized that the effect of objective and subjective speech depends on the topics that a VH speaks about and predicted that subjective speech is effective when a VH ...
Improving Social Presence with a Virtual Human via Multimodal Physical -- Virtual Interactivity in AR
CHI EA '18: Extended Abstracts of the 2018 CHI Conference on Human Factors in Computing SystemsIn a social context where a real human interacts with a virtual human (VH) in the same space, one's sense of social/co-presence with the VH is an important factor for the quality of interaction and the VH's social influence to the human user in context. ...
How we trust, perceive, and learn from virtual humans: The influence of voice quality
AbstractResearch has shown that creating environments in which social cues are present (social agency) benefits learning. One way to create these environments is to incorporate a virtual human as a pedagogical agent in computer-based learning ...
Highlights- Voice quality of a virtual human pedagogical agent can impact its trust ratings.
