我们已经调查了实际和感知人类的表现与一个简单的任务，包括步行和应用开发的知识，人机交互。基于涉及以“有目的和舒适”的步伐行走的实验，确定了梯形行走模型的参数：从静止开始，加速到恒定的步伐，以恒定的步伐行走，减速到停止。我们还收集了人类对完成一项简单任务（包括步行）的评估数据：确定从时间太短到适当时间的过渡，以及从适当时间到时间过长的过渡。研究发现，人们在估计短任务的持续时间时是准确的，但低估了长任务的持续时间。这些信息被应用于人机交互，涉及人类离开“片刻”，机器人知道任务需要多长时间以及人类如何评估时间。
We have investigated actual and perceived human performance associated with a simple task involving walking and applied the developed knowledge to a human-robot interaction. Based on experiments involving walking at a “purposeful and comfortable” pace, parameters were determined for a trapezoidal model of walking: starting from standing still, accelerating to a constant pace, walking at a constant pace, and decelerating to a stop. We also collected data on humans’ evaluation of the accomplishment of a simple task involving walking: determining the transitions from having taken too short a period of time to an appropriate time and from having taken an appropriate time to having taken too long. People were found to be accurate in estimating the task duration for short tasks, but to underestimate the duration of longer tasks. This information was applied to a human-robot interaction involving a human leaving for a “moment” and the robot knows how long the task should take and how time is evaluated by a human.
