Abstract. The tactile mechanism of texture perception is getting well figured out, resulting in the emergence of texture rendering devices. It is worth noting that the textures in these studies have interior space gap in the millimeter level and below. This kind of textures is called "fine texture". In contrast, the "Macro texture" has space gap in centimeters and above, and it is considered as the special texture with tiny texture pattern covered on curved surface. Compared with fine texture, macro texture contains richer surface information, including both roughness and curvature. This paper aims to study the mechanism of macro texture perception, and establish active and dynamic touch-based haptic perception models.

“…For example, users are able to know the home position on keyboard by perceiving bumps on "F" and "J" keys, which is the static tactile stimulus. Several techniques, which displays dynamic tactile stimulus on touchscreen, have already been developed [8,9]. In addition, there are some products utilizing this technique [10].…”

This study proposes a novel technique to display tactile sensation using electro-rheological fluid (ERF). ERF changes its rheological characteristics according to the electric field applied. The ERF used in this study generates relatively high yield stress and behaves as a solid when subjected to a strong electric field. Using this solid-liquid phase transition, we propose a novel device which provides a tactile sensation, i.e., tactile bump display. Applying electric field at a specific position in an ERF chamber, the corresponding ERF behaves as solid at the position. This solid-state ERF gives tactile sensation like a physical bump to a user. We fabricate in this study a prototype, which may realize the above-mentioned idea, and characterize it. We obtained the following results by experiments. First, the tactile bump display could make the users recognize their finger position on a flat surface by creating a tactile bump. Second, we confirmed that the tactile bump might significantly improve the accuracy and the precision of touch typing.

“…While this technology was highly scalable, it still needs high voltage supply to reach performant tactile rendering, and the user needs to be connected to the ground. On the other hand, Kotani, Takasaki and Mizuno created a transparent tactile device with a slider-based interface using ultrasonic (15 MHz) surface acoustic wave [12]. The periodic contact between the slider and the touch surface decreases the perceived surface roughness when the user moves the slider.…”

Tactile interfaces are intuitive but lack of haptic feedback. One method to provide tactile feedback is to change the friction coefficient of the touch surface. Several small-size tactile devices have been developed to provide programmable friction coefficient based on the squeeze air film effect. This effect is produced by ultrasonic vibration of the tactile plate thanks to piezoceramics. In order to design larger embedded tactile feedback areas, a key issue is the power consumption. In this paper, we present the power analysis of a tactile device which is based on the squeeze film effect. We first investigate the source of power consumption by a series of measurements. Then, an analytical model is developed to estimate the power, which gives the conclusion that, when the vibration amplitude is constant, the power consumption is not related to the number of piezoelectric actuators. According to this result, we design a large area (198mm × 138mm) tactile plate with only eight piezoelectric actuators. Experimental results show that the power consumption of the large tactile plate is less than 2 Watts. Moreover, we also find that the power consumption of the large tactile plate was predictable with the measurement results from small plates with an average error of less than 10%.
