Texture enhances haptic interaction by providing unique, distinguishable, and versatile surfaces. In computer haptics, texture can render environments more realistic and provide useful information. In this paper, an algorithm is proposed for virtual texture simulation by using solid noise, where only a few parameters need to be altered to generate a range of realistic and diverse textures by reproducing different frequencies similar to that of real vibrational signals in a virtual environment. The proposed method can capture the textural effect in a haptic simulation while retaining a simple overall geometry and stable update rate. This method also allows the user to change the texture at runtime and can be easily incorporated into any existing code and used in any traditional haptic device without affecting overall haptic-rendering performance. Moreover, the solid noise texture is independent of object geometry and can be applied to any shape without additional computations. We conducted a human-subject study to evaluate the recognition accuracy for each generated haptic texture as well as its realism and correspondence to real texture. The results indicated the high performance of the method and its ability to generate haptic textures with a very high recognition rate that were highly realistic.

纹理通过提供独特、可区分和多功能的表面来增强触觉交互。在计算机触觉中，纹理可以使环境更加逼真并提供有用的信息。在本文中，提出了一种使用固体噪声进行虚拟纹理模拟的算法，其中只需更改少数参数即可通过在虚拟环境中再现与真实振动信号相似的不同频率来生成一系列逼真多样的纹理。 . 所提出的方法可以在保持简单的整体几何形状和稳定的更新率的同时，在触觉模拟中捕捉纹理效果。这种方法还允许用户在运行时更改纹理，并且可以轻松地合并到任何现有代码中，并在任何传统触觉设备中使用，而不会影响整体触觉渲染性能。此外，固体噪声纹理独立于对象几何形状，可以应用于任何形状而无需额外计算。我们进行了一项人类受试者研究，以评估每个生成的触觉纹理的识别准确性及其真实性和与真实纹理的对应关系。结果表明该方法的高性能及其以非常高的识别率生成高度逼真的触觉纹理的能力。
