在设计精确的双手操作的触觉界面时，应该考虑到在单手和双手之间切换操作时如何实现重量模拟。在用户需要使用工具施加垂直力以穿透表面或使用一只手和/或两只手拼接易碎物体的任务中，这一点的重要性是显而易见的。对模拟重量的准确感知应该允许用户以高精度执行任务。在这里，我们评估了单手和双手的重量感知，当举起不同重量的虚拟箱子时，在一个耦合的主手指2设置精确抓地力。使用虚拟权重的初步结果与使用真实权重b[1]的研究结果相似，尽管用户似乎对虚拟权重不那么敏感。讨论了触觉界面设计的意义。
Design of haptic interfaces for precise bimanual manipulation should take into account how weight simulation is implemented when manipulation switches between one and two hands. The importance of this is apparent in tasks where the user requires to apply vertical forces to penetrate a surface with a tool or splice a fragile object using one and/or two hands. Accurate perception of simulated weight should allow the user to execute the task with high precision. Here, we evaluated unimanual and bimanual weight perception when lifting virtual boxes of different weights with precision grip in a coupled Master Finger 2 setup. Initial results with virtual weights are similar to results from studies which used real weights [1] even though the users appear to be less sensitive to virtual weights. Implications for haptic interface design are discussed.
