In this article, we aim to evaluate the role of robots’ personality-driven behavioural patterns on users’ intention to use in an entertainment scenario. Toward such a goal, we designed two personalities: one introverted with an empathic and self-comparative interaction style, and the other extroverted with a provocative and other-comparative interaction style. To evaluate the proposed technology acceptance model, we conducted an experiment (N = 209) at a public venue where users were requested to play a game with the support of (...) the TIAGo robot. Our findings show that the robot personality affects the acceptance model and three relevant drivers: perceived enjoyment, perceived usefulness, and social influence. The extroverted robot was perceived as more useful than the introverted, and participants who interacted with it were faster at solving the game. On the other hand, the introverted robot was perceived as more enjoyable but less useful than the extroverted, and participants who interacted with it made fewer mistakes. Taken together, these findings support the importance of designing proper robot personalities in influencing users’ acceptance, featuring that a given style can elicit a different driver of acceptance.

Contemporary ethics is currently ramifying into different sub-ethics specific to each type of technology. Although this trend has been very timely and rightly called into question by Sætra and Danaher, both these authors and their critics Llorca Albareda and Rueda leave the matter unsolved from a discipline point of view. In this commentary, we clarify the statute of the ethics of technology, which corresponds to that of a subsidiary applied ethics, and show how it is precisely that, what renders the (...) creation of an ethics for each technology inappropriate. We thus provide a disciplinary reason to support Sætra and Danaher’s concern on tech ethics proliferation and to refute Llorca Albareda and Rueda’s relativization of it. In turn, we conclude by drawing some guidelines for tech ethics in practice. (shrink)
