研究表明，工作负载和过去的机器性能会影响操作员对机器的任务职责分配。我们通过为任务操作员提供将任务控制权交给机器人实体的机会来扩展过去的调查。四十三名参与者在低或高时间压力的条件下驾驶遥控车辆沿着规定的路线行驶。在导航时，他们可以将摄像头监控分配给低或高可靠性的自动化代理。结果显示大多数参与者保留了对摄像机的控制；其他人立即放弃了控制权。时间压力和可靠性不会相互作用影响任务绩效。在高时间压力下，航向导航时间更快，但错误不受影响。双变量相关性揭示了机器人专业知识的自我评价与执行压力之间以及执行压力与导航过程中犯下的错误之间存在正相关关系。这些结果表明，人们对机器人摄像头的信任度较低，而且导航时间与时间压力的相对敏感性也较低。
Research has demonstrated that workload and past machine performance influences operator allocation of task responsibilities to machines. We extended past investigations by offering task operators the opportunity to relinquish task control to a robotic entity. Forty-three participants navigated a remotely controlled vehicle around a prescribed course under conditions of low or high time pressure. While navigating, they could allocate camera monitoring to a low-or high-reliability automated agent. Results showed most participants retained control of the camera; others relinquished control immediately. Time pressure and reliability did not interact to influence task performance. Course navigation time was faster under high time pressure but errors were unaffected. Bivariate correlations revealed a positive relation between self-ratings of robotic expertise and pressure to perform, and between pressure to perform and errors committed during navigation. These results demonstrate low levels of trust in the robotic camera and comparative sensitivity of navigation time to time pressure.
