论文摘要
触觉互动在人与人之间的互动中起着至关重要的作用。例如，触摸可以帮助人们冷静下来并降低生理压力反应。因此，人们认为触觉和触觉相互作用在人类机器人的相互作用中也很重要。我们研究触觉相互作用的强度是否对人们有影响，并通过研究触觉相互作用的不同强度是否调节生理指标和任务绩效来做到这一点。我们使用一个范式，其中使用小型类人机器人来鼓励冒险行为，依靠同行鼓励承担更多的风险，这可能会导致更高的回报，但也有可能带来更高的损失。为此，气球模拟风险任务（BART）被用作承担风险倾向的代理。我们研究了四个条件，其中一个在没有机器人的情况下完成任务的一个控制条件，以及存在机器人的三个实验条件，可以鼓励以不同程度的触觉相互作用来鼓励冒险行为。结果表明，低强度和高强度触觉相互作用都会增加人们的冒险行为。但是，低强度的触觉相互作用会增加舒适性并降低压力，而高强度的触觉不会。
Tactile interaction plays a crucial role in interactions between people. Touch can, for example, help people calm down and lower physiological stress responses. Consequently, it is believed that tactile and haptic interaction matter also in human-robot interaction. We study if the intensity of the tactile interaction has an impact on people, and do so by studying whether different intensities of tactile interaction modulate physiological measures and task performance. We use a paradigm in which a small humanoid robot is used to encourage risk-taking behaviour, relying on peer encouragement to take more risks which might lead to a higher pay-off, but potentially also to higher losses. For this, the Balloon Analogue Risk Task (BART) is used as a proxy for the propensity to take risks. We study four conditions, one control condition in which the task is completed without a robot, and three experimental conditions in which a robot is present that encourages risk-taking behaviour with different degrees of tactile interaction. The results show that both low-intensity and high-intensity tactile interaction increase people's risk-taking behaviour. However, low-intensity tactile interaction increases comfort and lowers stress, whereas high-intensity touch does not.
