Abstract
One approach to gauge the complexity of the computational problem underlying haptic perception is to determine the number of dimensions needed to describe it. In vision, the number of dimensions can be estimated to be seven. This observation raises the question of what is the number of dimensions needed to describe touch. Only with certain simplified representations of mechanical interactions can this number be estimated, because it is in general infinite. Organisms must be sensitive to considerably reduced subsets of all possible measurements. These reductions are discussed by considering the sensing apparatuses of some animals and the underlying mechanisms of two haptic illusions.
摘要
评估触觉感知背后的计算问题复杂性的一种方法是确定描述它所需的维度数。在视觉中，可以估计维度数为七。这一观察结果提出了一个问题，即描述触摸需要多少维度。只有在机械相互作用的某些简化表示的情况下，才能估计这个数字，因为它通常是无限的。生物体必须对所有可能测量的相当大的子集敏感。通过考虑一些动物的传感装置和两种触觉错觉的基础机制，可以讨论这些减少。
