Play is a common activity providing not only pleasure but also physical and cognitive development. In the quest for new playing experiences, there is an increasing tendency to develop robots playing with people. Making believable playing robots able to keep human players engaged and satisfied by the playing experience is the main challenge. In this work, we investigate the possibilities of a playful interaction between a human player and a mobile robot. In particular, this paper focuses on the applicability of deception as a means to support engagement and the attribution of rationality to playing robotic agents. By analyzing the interaction situation between the human and robot players, by identifying the need for deception, and by deciding whether and how to deceive, we aim at increasing self-reported engagement and fun, which are also related to the perception of the robotic opponent as smart enough to compete at an appropriate level. Experiments were conducted on a sample of 78 subjects facing two different deceptive behaviors and a basic behavior without any deception. All participants responded to a post-interaction questionnaire from which it was possible to observe a positive acceptance of the perception of the robot as a rational agent aimed at winning. In general, deception was perceived by most of the players as one of the robot’s abilities, when actuated, and contributed to the reported fun.

游戏是一种常见的活动，不仅提供娱乐，还提供身体和认知的发展。在寻求新的游戏体验时，越来越多的趋势是开发与人一起玩的机器人。使可信的游戏机器人能够使人类玩家对游戏体验保持参与和满意是主要的挑战。在这项工作中，我们研究了人类玩家和移动机器人之间进行有趣互动的可能性。特别是，本文着重于欺骗的适用性，以作为一种支持参与的手段，以及将合理性归因于扮演机器人特工。通过分析人与机器人玩家之间的互动情况，确定欺骗的需求，并确定是否以及如何欺骗，我们旨在增加自我报告的参与度和乐趣，这也与机器人对手足够聪明地在适当水平上进行比赛的感觉有关。实验是对78位受试者的样本进行的，这些受试者面临两种不同的欺骗行为和一种基本行为，没有任何欺骗。所有参与者都对互动后问卷进行了回答，从中可以观察到人们对机器人作为旨在获胜的理性行为者的看法的积极接受。通常，大多数玩家都认为欺骗是机器人在启动时的一项能力，并为举报的乐趣做出了贡献。所有参与者都对互动后问卷进行了回答，从中可以观察到人们对机器人作为旨在获胜的理性行为者的看法的积极接受。通常，大多数玩家都认为欺骗是机器人在启动时的一项能力，并为举报的乐趣做出了贡献。所有参与者都对互动后问卷进行了回答，从中可以观察到人们对将机器人视为赢家的理性推动者的看法的积极接受。通常，大多数玩家都认为欺骗是机器人在启动时的一项能力，并为举报的乐趣做出了贡献。
