@inproceedings { avelino18, abstract = {In this paper we study the influence of a handshake in the human emotional bond to a robot. In particular we evaluate the human willingness to help a robot whether the robot first introduces itself to the human with or without a handshake. In the tested paradigm the robot and the human have to perform a joint task, but at a certain stage the robot needs help to navigate through an obstacle. Without requesting explicit help to the human, the robot performs some attempts to navigate through an obstacle, suggesting to the human that it requires help. In a study with 45 participants, we measure the human’s tendency to help the social robot Vizzy, comparing the handshake vs non-handshake conditions. In addition, we evaluate the influence of a handshake in the pro-social behavior of helping it and the willingness to help it in the future. The results show that handshake condition affects the Warmth, Animacy, Likeability, and willingness to help in the future. Nevertheless, participants tend to better understand the robot needs for help in the handshake condition.}, booktitle = {2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)}, keywords = {Task analysis;Navigation;Haptic interfaces;Human-robot interaction;Tactile sensors;Social Robotic Companions;}, month = {Oct}, pages = {1864-1869}, title = {The Power of a Hand-shake in Human-Robot Interactions}, year = {2018}, author = {João Avelino and Filipa Correia and João Catarino and Pedro Ribeiro and Plinio Moreno and Alexandre Bernardino and Ana Paiva} }
