摘要:

在过去的二十年里,对自动化的信任,或者最近对自主性的信任,受到了广泛的研究关注。大多数先前的文献采用了“快照”的信任的观点,通常通过在实验结束时进行问卷调查来评估信任。然而,这种“快照”观点没有承认信任是一个随时间变化的变量,可以随着时间的推移而加强或衰减。为了填补研究空白,本研究的目的是模型的信任动态时,人类与机器人代理随着时间的推移进行交互。该研究的基本前提是,通过与机器人代理进行交互并观察其随时间的表现,理性的人类代理将相应地更新他/她对机器人代理的信任。在此基础上,提出了一种基于Beta分布的个性化信任预测模型,并利用贝叶斯推理学习模型参数。我们提出的模型坚持三个主要属性的信任动态在以前的实证研究报告。我们使用现有的数据集测试了所提出的方法,该数据集涉及39名人类参与者在模拟监视任务中与4架无人机进行交互。所提出的方法获得了0.072的均方根误差(RMSE),显着优于现有的预测方法。此外,我们确定了三种不同类型的信任动态,贝叶斯决策者,振荡器,和不信者,分别。该预测模型可用于个性化和自适应技术的设计。

英文摘要:

Trust in automation, or more recently trust in autonomy, has received extensive research attention in the past two decades. The majority of prior literature adopted a "snapshot" view of trust and typically evaluated trust through questionnaires administered at the end of an experiment. This "snapshot" view, however, does not acknowledge that trust is a time-variant variable that can strengthen or decay over time. To fill the research gap, the present study aims to model trust dynamics when a human interacts with a robotic agent over time. The underlying premise of the study is that by interacting with a robotic agent and observing its performance over time, a rational human agent will update his/her trust in the robotic agent accordingly. Based on this premise, we develop a personalized trust prediction model based on Beta distribution and learn its parameters using Bayesian inference. Our proposed model adheres to three major properties of trust dynamics reported in prior empirical studies. We tested the proposed method using an existing dataset involving 39 human participants interacting with four drones in a simulated surveillance mission. The proposed method obtained a Root Mean Square Error (RMSE) of 0.072, significantly outperforming existing prediction methods. Moreover, we identified three distinctive types of trust dynamics, the Bayesian decision maker, the oscillator, and the disbeliever, respectively. This prediction model can be used for the design of individualized and adaptive technologies.
