@inproceedings { paradeda20, abstract = {In social robotics, user-personalised messages is a technique that can be used to persuade a person to do something. Those messages can be personalised according to the personality of whom will receive this message. So, it is essential to know the personality traits of the target. However, we have many traits, e.g., a person can be extroverted, assertive, logical, among others. Because of that, it is challenging to create a strategy that can reach all the traits. In this sense, we chose to focus our persuasion strategies to approach the assertive trait of a person. The strategies were applied in a storytelling scenario with an autonomous social robot behaving assertively using strategies to suggesting the person change the decision with assertive messages and nonverbal persuasive techniques. Besides, we take into account the assertiveness level of the participant to measure if this level influences the acceptance of robot suggestion or not. We observed from the results that a person's assertiveness level might influence the perception regarding the persuasive agent and the decisions-made in the task.}, address = {Cham}, booktitle = {Social Robotics}, keywords = {Intelligent Interactive Storytelling;}, pages = {516--528}, publisher = {Springer International Publishing}, title = {The Importance of the Person's Assertiveness in Persuasive Human-Robot Interactions}, year = {2020}, author = {Raul Benites Paradeda and Maria José Ferreira and Carlos Martinho and Ana Paiva} }
