为了探索多感官信息可能有助于扩大虚拟环境中触觉体验范围的可能性，进行了心理物理学实验，检查声音对刚度触觉感知的影响。在这些实验中，受试者使用 PHANToM（一种具有沿三个轴的力反射功能的六自由度触觉接口设备）来感受各种虚拟表面的刚度。当受试者敲击不同的虚拟表面时，他们会同时听到各种撞击声音。受试者被要求根据他们感知到的硬度对表面进行排名。结果表明，当表面的物理硬度相同时，受试者一致根据声音对表面进行排名，即与通常与敲击较硬表面相关的声音提示配对的表面通常被认为更坚硬。然而，当声音提示与不同机械刚度的表面随机配对时，结果更加模棱两可：以前没有使用过 PHANToM 的天真的受试者比之前完成了一组没有声音提示的刚度辨别实验的另一组受试者更容易受到声音提示的影响。讨论了这一结果对多模式虚拟环境设计的可能影响，以及与一些作者之前关于视觉对触觉感知影响的研究的比较。
To explore the possibility that multisensory information may be useful in expanding the range of haptic experiences in virtual environments, psychophysical experiments examining the influence of sound on the haptic perception of stiffness were carried out. In these experiments, subjects utilized the PHANToM, a six-degree-of-freedom haptic interface device with force-reflection along three axes, to feel the stiffness of various virtual surfaces. As subjects tapped on the different virtual surfaces, they were simultaneously presented with various impact sounds. The subjects were asked to rank the surfaces based on their perceived stiffness. The results indicate that when the physical stiffnesses of the surfaces were the same, subjects consistently ranked the surfaces according to sound, i.e., surfaces paired with sound cues that are typically associated with tapping harder surfaces were generally perceived as stiffer. However, when sound cues were randomly paired with surfaces of different mechanical stiffnesses, the results were more equivocal: naïve subjects who had not used the PHANToM previously tended to be more affected by sound cues than another group of subjects who had previously completed a set of stiffness discrimination experiments without sound cues. The possible implications of this result for the design of multimodal virtual environments and its comparison to prior work by some of the authors on the effects of vision on haptic perception are discussed.
