真实的或虚拟表面的纹理既可以增加物体的真实感，也可以传达物体的身份、类型、位置、功能等信息，因此，界面设计者了解虚拟环境中现有交互设备提供给他们的纹理信息的范围是很重要的。之前的工作（例如[2]）检查了一组力反馈生成的纹理（通过PHANToM设备传达）的感知粗糙度，以便努力实现这样的理解。在这样做的时候，这项工作已经突出了可能的感知限制，涉及可靠和自信地判断一组触觉纹理的相对粗糙度。例如，我们可以区分多少种纹理，我们有多大可能可靠地判断任何一种纹理比另一种粗糙，不那么粗糙或相同？这里提出的工作经验调查的影响，增加听觉纹理线索现有的触觉纹理。例如，额外线索（在听觉模态中）的存在是否会改变我们对上述问题的回答？我们建议，除了听觉刺激将增加潜在的范围和分辨率的纹理粗糙度感知可通过力反馈相互作用。
The texture of a real or virtual surface can both increase the sense of realism of an object as well as convey information about an object's identity, type, location, function, and so on. It is important therefore that interface designers understand the range of textural information available to them through current interaction devices in virtual environments. Previous work (e.g. [2]), has examined the perceived roughness of a set of force feedback generated textures (conveyed via a PHANToM device) in order to work towards such an understanding. In doing so, this work has highlighted the possible perceptual limitations involved in reliably and confidently judging the relative roughness of a set of haptic textures. How many textures can we distinguish between for example and how likely is it that we reliably judge any one as rougher than, less rough than or the same as the other? The work presented here empirically investigates the effects of adding auditory textural cues to the existing haptic textures. Does the existence of an additional cue (in the auditory modality) change the answers to our questions above for example? We propose that the addition of auditory stimuli will increase the potential range and resolution of texture roughness percepts available through force feedback interaction.
