我们的互动伙伴自然而然地倾向于拟人化，并利用在早期互动场景中获得的经验，这导致了人们认为与类人机器人的社交互动比与工业机器人的社交互动更愉快和直观。基于运动干扰(MI)现象，提出了一种客观评价人机交互质量的方法。它声称，面对面地观察另一个人的不同(不协调的)运动会导致一个人自己的运动轨迹出现更大的差异。在社会交往中，MI是模仿他人运动的倾向的结果，伴随着相互融洽、团结感和同情心。虽然MI是在观察人类代理人时发生的，但在工业机器人以分段恒定速度移动的情况下，MI会消失。最近的一项研究表明，使用一个外表与人类相似的机器人，只有当它们基于人类的预先记录(生物速度)，而不是恒定的(人工)速度轮廓时，它的运动才会导致MI。然而，它仍然不清楚，是人类预先记录的运动的哪些方面触发了MI：生物速度分布还是运动轨迹的可变性。为了研究这一问题，我们将一种准生物的最小抖动速度分布(不包括运动轨迹的变异性作为MI的影响因素)应用到类人机器人的运动中，由执行一致或不一致手臂动作的受试者观察到。受试者的动作变异性的增加既发生在观察人类代理人的过程中，也发生在机器人执行不协调动作的情况下，这表明人造的类似人类的运动速度分布足以促进类人机器人作为交互伙伴的感知。
The automatic tendency to anthropomorphize our interaction partners and make use of experience acquired in earlier interaction scenarios leads to the suggestion that social interaction with humanoid robots is more pleasant and intuitive than that with industrial robots. An objective method applied to evaluate the quality of human-robot interaction is based on the phenomenon of motor interference (MI). It claims that a face-to-face observation of a different (incongruent) movement of another individual leads to a higher variance in one's own movement trajectory. In social interaction, MI is a consequence of the tendency to imitate the movement of other individuals and goes along with mutual rapport, sense of togetherness, and sympathy. Although MI occurs while observing a human agent, it disappears in case of an industrial robot moving with piecewise constant velocity. Using a robot with human-like appearance, a recent study revealed that its movements led to MI, only if they were based on human prerecording (biological velocity), but not on constant (artificial) velocity profile. However, it remained unclear, which aspects of the human prerecorded movement triggered MI: biological velocity profile or variability in movement trajectory. To investigate this issue, we applied a quasi-biological minimum-jerk velocity profile (excluding variability in the movement trajectory as an influencing factor of MI) to motion of a humanoid robot, which was observed by subjects performing congruent or incongruent arm movements. The increase in variability in subjects' movements occurred both for the observation of a human agent and for the robot performing incongruent movements, suggesting that an artificial human-like movement velocity profile is sufficient to facilitate the perception of humanoid robots as interaction partners.
