长期以来，文献一直建议计算机输入设备的设计应该利用手指中细小的肌肉群和关节，因为它们在人类运动和感觉皮层中有丰富的代表，并且它们比其他身体部位具有更高的信息处理带宽。然而，这一假设尚未得到实证研究的最终验证。目前的工作研究了这样的假设的背景下，设计6自由度（DOF）的输入设备。这项工作试图解决实际需要-设计高效的6自由度输入设备-和输入控制中的肌群差异的理论问题。两个替代的6自由度输入设备，一个包括和其他不包括手指的6自由度操作，设计和测试中的3D对象对接实验。使用手指的设备，用户的任务完成时间明显缩短。这项研究的结果强烈表明，未来的输入设备设计的形状和大小应构成启示，邀请手指参与输入控制。
The literature has long suggested that the design of computer input devices should make use of the fine, smaller muscle groups and joints in the fingers, since they are richly represented in the human motor and sensory cortex and they have higher information processing bandwidth than other body parts. This hypothesis, however, has not been conclusively verified with empirical research. The present work studied such a hypothesis in the context of designing 6 degree-of-freedom (DOF) input devices. The work attempts to address both a practical need - designing efficient 6 DOF input devices - and the theoretical issue of muscle group differences in input control. Two alternative 6 DOF input devices, one including and the other excluding the fingers from the 6 DOF manipulation, were designed and tested in a 3D object docking experiment. Users' task completion times were significantly shorter with the device that utilised the fingers. The results of this study strongly suggest that the shape and size of future input device designs should constitute affordances that invite finger participation in input control.
