It Would Make Me Happy if You Used My Guess: Comparing Robot Persuasive Strategies in Social Human–Robot Interaction

This letter presents an exploratory social human–robot interaction (HRI) study that investigates and compares the persuasive effectiveness of robots attempting to influence a user with different behavior strategies. Ten multimodal persuasive strategies were uniquely designed based on compliance gaining behaviors. These persuasive strategies were then compared using two competing social robots attempting to influence participant's estimate during a jelly bean guessing game. The results of our exploratory study with 200 participants showed that affective and logical strategies had a higher potential for persuasive influence and warrant further research.
