柔软或可变形的物体，无论是橡皮鸭还是跑鞋衬垫，很少被认为是机械振动的来源。出于类似的原因，人们经常忽视材料的柔软度可以通过振动触觉感觉通道（即通过对机械振动敏感的触觉感知系统的子集）进行传达。在本章中，我们回顾了有关振动触觉和柔软知觉之间关系的现有知识。可以区分两种主要类型的柔软度感知，一种与触摸物体的表面材料质量有关，另一种与体积顺应性相关。这些信息可以通过四种类型的相互作用获得，将分别进行分析：直接皮肤接触、间接皮肤接触、瞬时接触、摩擦滑动。我们回顾了这四种情况下柔软感知的当代研究。这项研究揭示了振动触觉刺激的感知显着性以及振动触觉线索对柔软度的动作阶段依赖性。我们还强调了相互作用的生理和机械方面对于柔软度感知的重要性。在大多数情况下，与其他章节中描述的通过直接操纵具有可变形表面的柔顺物体产生的提示相比，振动触觉提示对感知的影响相对较弱。尽管如此，振动会导致感知依从性发生明显变化，除了其他线索之外或当此类线索不可用时，可以利用这种变化。
Soft or deformable objects, be they rubber ducks or running shoe inserts, are rarely thought of as sources of mechanical vibrations. For similar reasons, it is often overlooked that material softness can be communicated through the vibrotactile sensory channel—that is, through the subset of the haptic perceptual system that is sensitive to mechanical vibration. In this chapter we review current knowledge about the relation between vibrotactile sensation and softness perception. It is possible to distinguish between two main types of softness perception—one pertaining to the surface material qualities of a palpated object and the other linked to volumetric compliance. This information can be obtained through four types of interactions, which will be analysed separately: direct skin contact, indirect skin contact, transient contact, frictional sliding. We review contemporary research on softness perception in these four scenarios. This research has shed light on the perceptual salience of vibrotactile stimuli and on the action-phase dependence of vibrotactile cues for softness. We also highlight the importance of the physiological and mechanical aspects of the interactions for softness perception. In most cases, vibrotactile cues have a comparatively weaker influence on perception than the cues described in other chapters produced by directly manipulating a compliant object with deformable surfaces. Nonetheless, vibrations lead to an appreciable change on perceived compliance that can be exploited in addition to other cues or when such cues are not available.
