虚拟世界必须结合触觉和力感来创造一种存在感。我们的触觉显示器将物体表面的纹理感传递给用户的指尖。这种振动触觉显示器包含一个将振动传递到人体皮肤的接触针阵列。自20世纪60年代以来，这种设备一直被研究作为盲人的阅读辅助设备。由J.G.林维尔和J.C.布利斯（1966）开发的一种名为Optacon的设备是为视力受损的人设计的。因此，表示纹理的方法尚未对该设备进行广泛讨论。我们提出了通过振动触觉显示虚拟复制表面纹理感觉的技术，使用物体的图像数据。M. Minsky等人（1990）展示了一种通过力显示来呈现表面纹理的方法，如果需要的话，还包括纹理的视觉图像。他们的系统根据深度图的几何形状生成图像。相反，我们使用真实物体表面的图片来提供触觉刺激的分布数据。
Virtual worlds must integrate tactile and force sensations to create a sense of presence. Our tactile display conveys the textural sensation of object surfaces to a user's fingertip. This vibratory tactile display contains a contact pin array that transmits vibrations to the human skin. This type of device has been investigated as a reading aid for the blind since the 1960s. A device called the Optacon, developed by J.G. Linvill and J.C. Bliss (1966) was intended for use by a visually impaired person. Therefore, methods for representing texture have not been discussed extensively for that device. We present techniques for virtually replicating surface texture sensations through a vibratory tactile display, using image data of objects. M. Minsky et al. (1990) demonstrated a method for presenting surface textures by force display, including-if needed-visual images of textures. Their system generated the images from geometrical shapes of depth maps. In contrast, we use pictures of real object surfaces to provide the distribution data for tactile stimulus.
