Haptic texture rendering has recently received a lot of attention among the haptic community. By adding haptic textures onto an object could enhance its realism. The objective of this paper is to propose a rendering method that could improve such realism. We examine haptic rendering techniques that involve sine waves and Fourier series, and identify any problems that may occur. We argue that haptic texture rendering can employ 2D texture images data to generate the haptic texture, and suggest that wavelet transformations could be used to filter the texture information and generate haptic texture surfaces. Thus, a rendering method based on an image’s visual information is proposed. We conducted a study to compare the three different haptic rendering techniques i.e. using sine waves, Fourier series and visual texture information. The findings indicate that the technique based on object’s visual texture information supports a more realistic haptic texture rendering.
