s挥舞着一根封闭的l形杆，并试图感知杆相对于手指向的方向。由惯性张量量化的杆在不同方向上的不同旋转阻力的模式，随着杆的方向系统地变化。如果可以检测到杆的惯性张量的组织变形后果，则可以通过挥舞来感知方向。结果表明，在自由摆动和受限摆动以及具有不同大小分支的杆的情况下，感知取向是实际取向的线性函数。惯性张量的特征向量是这种触觉感知能力的基础。结果讨论了信息感知特异性及其对努力或动态触摸的影响。
Ss wielded an occluded L-shaped rod and attempted to perceive the direction in which the rod was pointing with respect to the hand. The pattern of the rod's different resistances to rotation in different directions, quantified by the inertia tensor, changes systematically with the rod's orientation. Perception of orientation by wielding is possible if the tissue deformation consequences of the rod's inertia tensor are detectable. It was shown that perceived orientation was a linear function of actual orientation for both free and restricted wielding and for rods of different-size branches. The eigenvectors of the inertia tensor were implicated as the basis for this haptic perceptual capability. Results were discussed in reference to information-perception specificity and its implications for effortful or dynamic touch.
