作者介绍了一种基于表面高度图的振动针阵触觉纹理呈现方法。该方法利用直方图变换获得感觉强度图，在显示设备上产生真实纹理样本斑块的模拟触觉刺激。通过对6个候选数据的收集和比较，确定了直方图变换的参数。在纹理显示器和Optacon II两种显示器上测试了五种不同的壁纸补丁。在纹理显示的情况下，受试者在参数选择上的变化较小；此外，在粗糙度-平滑度维度上对显示呈现的评价结果与纹理的直接触感接近。对于Optacon II，首先在振动概率控制的基础上进行感觉缩放。虽然控制模式受到Optacon II原始设计的严格限制，但通过与纹理显示相同的方法可以正确地感知样品纹理。
The authors introduce a method for presenting tactile textures by using vibratory pin arrays, which is based on a surface-height map. The method utilizes a histogram transformation to obtain a sensation intensity map, which produces simulated tactile stimuli of real texture sample patches on display devices. Parameters of histogram transformation were determined by an experiment in which data from six candidates were gathered and compared. Five different wallpaper patches were examined on two displays, the Texture Display and the Optacon II. In the case of the Texture Display, subjects showed small variation in parameter selection; in addition, the evaluation of display presentation in the roughness-smoothness dimension exhibited a result close to that of the direct touch of textures. In the case of the Optacon II, a sensation scaling was performed first on the basis of vibration probability control. Although the control mode possessed severe restrictions derived from the original design of the Optacon II, the sample textures were perceived properly by the same method as that employed with the Texture Display.
