“…The objective of the present study is to investigate whether a texture display combining vibrotactile and variable-friction stimuli presents better texture stimuli. Thus far, no studies except for our previous ones [22,23] have attempted to combine the two types of stimuli for developing quality tactile textures; however, one study reported a tactile display that could deliver both types of stimuli [41,43] using vibrotactile and friction stimuli separately for presenting fine textures and macroscopic surface profiles, respectively. The friction distribution on a plane leads to the perception of macroscopic surface profiles such as bumps and holes [26,39,42].…”

“…Our previous experiments [22,23] indicated that the combination of two types of tactile stimulations is effective for improving the realism of virtual roughness textures. In the experiments, participants perceived virtual grating scales under three conditions: textures presented by vibrotactile stimuli, electrostatic friction, and the conjunction of vibrotactile and friction stimuli.…”

“…In this study, we investigate the composition ratio of the two types of tactile stimulations for achieving better realism when the spatial wavelengths of virtual grating scales vary between 0.5 and 3.0mm. In other words, we compared 11 conditions, 9 of which are conjunction conditions with different vibrotactile-electrostatic composition rates whereas our previous studies [22,23] tested only one conjunction condition. The acquisition of a better composition ratio for each roughness scale would contribute to the design of the hardware and rendering algorithms of tactile texture displays.…”

Vibrotactile and friction texture displays are good options for artificially presenting the roughness and frictional properties of textures, respectively. These two types of displays are compatible with touch panels and exhibit complementary characteristics. We combine vibrotactile and electrostatic friction texture displays to improve the quality of virtual textures, considering that actual textured surfaces are composed of both properties. We investigate their composition ratios when displaying roughness textures. Grating roughness scales with one of the six surface wavelengths are generated under 11 display conditions, and in 9 of which, vibrotactile and friction stimuli are combined with different composition ratios. A forced-choice experiment regarding subjective realism indicates that a vibrotactile stimulus with a slight variable-friction stimulus is effective for presenting quality textures for surface wavelengths greater than or equal to 1.0mm.

Electrostatic tactile representation technology can enhance the authenticity and immersion of human-computer interaction by perception of tactile features such as the shape and texture of visual objects in touch screen in naked finger. Focusing on the application in multimedia terminal of electrostatic force tactile representation technology, this paper summarizes the typical devices of electrostatic tactile representation, tactile rendering model-driven and data-driven algorithm, driving signal loading method, tactile representation effect evaluation method and so on. The author's view on the development status and future prospects of this technology is presented as follows: (1) Electrostatic tactile representation technology is an optimization scheme for implementing the low power and bare finger tactile representation function on the surface of the multimedia terminal; (2) The rendering dynamic range of electrostatic tactile representation technology is still insufficient, and the rendering effect of rough texture is better, but there is no effective algorithm for the rendering of fine texture. Multiple fusion technology may be one of the solutions; (3) From the perspective of evaluation of tactile representation effect, which shows that there is still considerable room for improvement both in theoretical models and applied algorithms; (4) Electrostatic tactile representation technology is essentially an applied science. Mutual promotion and benign promotion of theoretical research and commercial application is the only way for its progress. Therefore, a more mature prototype of principle is urgently needed to be popularized and applied in commerce.
