“…The authors in [42], [63]- [68] recorded such highfrequency acceleration signals using tool-mediated setups and created data-driven models for tactile display. The work in [69] additionally considers the speed components v x and v y to account for anisotropic (i.e., direction-depending) haptic textures, e.g., wooden structures.…”

“…These ARMA coefficients can be transmitted over a network, and, depending on the exerted force and velocity, the displayed tactile signal is generated by filtering a white noise signal using the received ARMA coefficients. The work in [69] further improved the procedure to take anisotropic surface properties into account and proposed a compression scheme for n-dimensional data-driven tactile signal representations which considers the dimensions of scan force and scan velocity in x and y dimensions and report a two-fold compression rate. Based on Weber's law, [58] presents a frequency-domain compression algorithm for tactile information.…”

“…人体触感形成的机理十分复杂 [47] ,且与个体的心理和生理等有关,评价用户在触觉再现终端上 感受到的触觉效果涉及到电子学、生理学、心理学、精神物理学等多学科的交叉问题。当前对静电 力触觉再现效果的评价主要从客观和主观两方面进行(图 32)。客观评测主要是搭建力测量平台,测 图 27 Abdulali 等研发的纹理采集装置 [42] Figure 27 Texture acquisition device developed by Abdulali et al [42] 图 28 Ilkhani 等研发的纹理采集装置 [43] Figure 28 Texture acquisition device developed by Ilkhani et al [43] 图 29 电动线性摩擦计 [44] Figure 29 Electric linear tribometer.

“…In the field of haptics, there are two main classes of the sample selection algorithms. First class is represented by wrapper methods where the complete set is trained and reduced iteratively [ 45 ]. The selection process of this algorithm is guided by the approximation model, which enhances the selection quality.…”
