双手协调在许多触觉和机器人系统操作中起着至关重要的作用。然而，双手人类运动控制的理论很少被集成到人在环机器人的控制系统中，这可能限制了人类和机器人之间的可用性和协作潜力，特别是对于复杂的任务，如机器人手术。为了通知未来的集成，我们调查未知的手动性能关系的缩放（一只手的运动的大小相比，其他）和序列（手移动的顺序）的复杂双手路径以下的任务。对于缩放变化，左手或右手期望轨迹幅度增加。对于序列，任务被分割，以便手顺序或同时移动。该实验由11名缺乏经验的健全受试者（均为右撇子）在虚拟环境中使用触觉设备进行。结果显示，当对侧手缩放时，一只手的手动性能显著降低（[公式：见正文]），因此表明一只手的比例增加将降低对侧的性能。结果还表明，当与右手同时移动时，左手的性能显著下降，但右手没有表现出这样的性能下降。这可能表明，只有非优势手患有同时运动条件。这些结果可能会导致独特的机会，整合到复杂的双手上肢任务中使用的触觉和机器人系统的控制系统与人类运动控制相关的理论。
Bimanual coordination plays a vital role in many haptic and robotic system operations. However, theories in bimanual human motor control are rarely integrated into the control system for human-in-the-loop robots, potentially limiting the usability and collaborative potential between the human and robot, particularly for complex tasks such as robotic surgery. To inform future integration, we investigate unknown manual performance relationships regarding the scaling (the size of one hand’s motions compared to the other) and sequence (the order in which the hands move) of complex bimanual path following tasks. For scaling variations, either the left or right hand desired trajectory amplitude was increased. For sequence, the task was split so that the hands moved sequentially or simultaneously. The experiment is performed by 11 inexperienced, able bodied subjects (all right-handed) in a virtual environment while using haptic devices. Results show significant ([Formula: see text]) decreased manual performance for one hand when the opposite hand is scaled, thus suggesting an increase in the scale of one hand will decrease the performance of the contralateral. Results also show a significant decrease in performance for the left hand when moving simultaneous with the right, but the right hand does not show such a decrease in performance. This might suggest that only the nondominant hand suffers from simultaneous motion conditions. These results may lead to unique opportunities to integrate theories related to human motor control into the control system for haptic and robotic systems used in complex bimanual upper-limb tasks.
