Humanoid robots can be an effective tool for the cognitive training of older adults. For this purpose, it is important that their interaction be engaging. In this study, we investigate whether proposing robots exhibiting extraverted or introverted personalities can improve user experience. In particular, we have designed and implemented a set of multi-modal cues for such personality traits, which have been exploited in an application proposing typical exercises for cognitive training through a Pepper robot. We report on a user test with 24 older adults (65 +), which provided interesting and positive feedback regarding how the robot personalities have been exhibited and their impact on the experience of such users.

人形机器人可以成为老年人认知训练的有效工具。为此，重要的是他们的互动具有吸引力。在这项研究中，我们研究了提出表现出外向或内向性格的机器人是否可以改善用户体验。特别是，我们为此类人格特征设计并实现了一组多模式线索，这些线索已在通过 Pepper 机器人提出典型认知训练练习的应用程序中得到利用。我们报告了对 24 名老年人（65 岁以上）进行的用户测试，该测试提供了有关机器人个性如何展示及其对此类用户体验的影响的有趣且积极的反馈。
