摘要:

我们的目标是使机器人能够以一种有目的地表达其内部状态的方式来\emph{time}它们的运动,使它们对人类更加透明。我们首先调查什么类型的状态运动时序能够表达,专注于机器人操作和保持路径不变,同时系统地改变定时。我们发现,用户自然会注意到机器人的某些属性(如自信),运动(如自然)或任务(如机器人携带的物体的重量)。然后,我们进行了一个假设驱动的实验,梳理出这些影响的方向和幅度,并使用我们的研究结果来开发候选数学模型,用于用户如何从时间上做出这些推断。我们发现模型和真实的用户数据之间有很强的相关性,这表明机器人可以利用这些模型来自主优化其运动的时机,以表现力。

英文摘要:

Our goal is to enable robots to \emph{time} their motion in a way that is purposefully expressive of their internal states, making them more transparent to people. We start by investigating what types of states motion timing is capable of expressing, focusing on robot manipulation and keeping the path constant while systematically varying the timing. We find that users naturally pick up on certain properties of the robot (like confidence), of the motion (like naturalness), or of the task (like the weight of the object that the robot is carrying). We then conduct a hypothesis-driven experiment to tease out the directions and magnitudes of these effects, and use our findings to develop candidate mathematical models for how users make these inferences from the timing. We find a strong correlation between the models and real user data, suggesting that robots can leverage these models to autonomously optimize the timing of their motion to be expressive.
