有人认为，惯性张量支配着触觉的许多实例。然而，证据是不确定的，因为其他候选力学参数(即不变量)在相关实验中没有或没有得到足够的控制。通过独立地改变所有候选力学参数，作者能够测试惯性张量相对于其他力学参数的作用。结果表明，挥杆过程中的长度知觉不仅受惯性张量的支配，还受静力矩的支配。与以往的报道不同，握杆时的长度感觉和挥杆时的重量感觉与惯性张量无关，而与静力矩密切相关。
It has been suggested that the inertia tensor governs many instances of haptic perception. However, the evidence is inconclusive because other candidate mechanical parameters (i.e., invariants) were not or were insufficiently controlled for in pertinent experiments. By independently varying all candidate mechanical parameters, the authors were able to test the role of the inertia tensor relative to that of other mechanical parameters. The results showed that length perception during rod wielding is not governed by the inertia tensor alone but also by the static moment. In contrast to previous reports, length perception during rod holding and heaviness perception during rod wielding were found to be unrelated to the inertia tensor and strongly related to the static moment.
