间歇性和可变的时间延迟的影响进行了研究，以了解从操作员的输入和相应的反馈响应从系统之间的差距的认知和物理后果。时间延迟已经被证明会破坏包括心理学和遥控机器人在内的各个领域的任务表现。以前的研究在多个领域集中在时间延迟的性能影响和克服技术限制，导致时间延迟。然而，机器人研究人员还没有研究可变的时间延迟对特定操作员的情绪，可用性和生理激活的遥操作的影响。本研究探讨了可变时延不仅对任务绩效的影响，而且对操作者的情绪、生理唤醒、认知负荷和遥操作的可用性也有影响。通过在系统反馈中引入滞后来控制时滞。参与者被要求在远程位置通过不同级别的任务复杂性的迷宫，同时识别目标的远程控制机器人车辆。结果表明，操作员的挫折感，愤怒和工作量增加，而可用性和任务性能下降时，间歇性和可变的反馈滞后引入到机器人导航任务。可变时间延迟的影响大于任务复杂性的影响。此外，研究结果表明，时间延迟和任务复杂性的影响是加性的。更好地理解人类操作员的情感体验和相应的生理信号对于设计具有适当减轻负面操作员情感状态的能力的情感感知机器人系统至关重要。
The effects of intermittent and variable time delay were investigated to understand the cognitive and physical consequences of gaps between an input from an operator and the corresponding feedback response from the system. Time delay has been shown to disrupt task performance in various areas including psychology and telerobotics. Previous research in multiple domains has focused on the performance effects of time delay and overcoming technological limitations that cause time delay. However, robotics researchers have yet to study the effects of variable time delay on specific operator emotions, usability, and physiological activation in teleoperations. This study investigates the influence of variable time delay not only on task performance, but also operator emotions, physiological arousal, cognitive workload, and usability in teleoperation. Time delay was manipulated by introducing lag into the system feedback. Participants were asked to navigate a remote-control robot vehicle through mazes of differing levels of task complexity in a remote location and simultaneously identify targets. Results showed that operator frustration, anger, and workload increased while usability and task performance decreased when intermittent and variable feedback lag was introduced to a robotic navigation task. The effect of the variable time delay was greater than the effect of task complexity. Furthermore, results suggest that the effects are of time delay and task complexity are additive. A better understanding of the emotional experiences of human operators and the corresponding physiological signals is of crucial importance to designing affect-aware robotic systems that have the ability to appropriately mitigate negative operator emotional states.
