作者研究了一种触觉纹理呈现方法，通过触觉纹理显示来传达物体表面纹理的感觉。通过对两个简单形状的真实纹理块的实验，证明了表面纹理图像数据（仔细拍摄的B/W照片）与表面几何数据（高度图）是兼容的。由于原始几何数据（即原始图像）不适合纹理显示，他们提出采用直方图变换使数据产生的感觉更接近真实。他们从50个直方图变换中获得了两个，通过这个变换，几何数据被调整，这样他们就可以最好地产生关于六个真实斑块的纹理感觉。经过转换后的数据与实际补丁进行了比较，新手用户的感觉较好。
The authors have investigated a tactile texture presentation method by which a tactile texture display is driven to convey the sensations of object's surface textures. The image data (a B/W photograph taken carefully) of surface textures proved to be compatible with the surface geometry data-a height map-by an experiment with two simple-shape real texture patches. As a raw geometry data-hence a raw image-was not suitable for the texture display, they proposed to apply a histogram transformation to make the sensation produced by the data close to the real one. They obtained two histogram transformations out of fifty, by which the geometry data were adjusted so that they could best produce texture sensations regarding six real patches. The data adjusted by the transformations proved to present appropriate sensations to novice users who compared the data and the real patches tactually.
