“…In contrast, digital touch designed for contexts and markets of appeal to men, are actualised through hard plastic and vibration, as well as the user scenarios related to work and leisure. Emerging interfaces, such as TanvasTouch (Shultz et al 2015), enable users to 'feel what you see' and imagine the development of 'textual emojis' through feeling texture of the digital online. For example, Gillet's 'Baby Face' digital and print campaign used TanvasTouch and the feel of sandpaper -a texture and resource associated with the 'masculine' practice of DIY, to convey the 'scratch' of a new father's beard on their baby (https://www.youtube.…”

This chapter discusses social norms with attention to their significance for researching and designing digital touch communication in a global world, notably gendered and cultural touch norms. It explores how social and cultural norms shape the ways that people (and machines) touch. Touch norms are shaped, regulated and enforced through social, economic, familial and legal mechanisms, they organise our experiences and expectations. Understanding of the touch norms that people, including digital touch researchers and designers, bring to their interactions with others provides a route into understanding the sociality that shapes digital touch. We discuss the significance of these given the expectations of the user, their touch repertoires, and the social cultural role that norms play in the take up and use of mediated digital touch communication devices and systems and environments. The chapter concludes that reflexive engagement with touch norms can provide insights and inspiration for thinking about, researching and designing digital touch communication, and help to address how cultural and gendered norms of touch might be engaged with, to constrain and reproduce or open-up the meaning potentials of digital touch.

“…For example, a study reports that electrostatically modulated friction force exerted on a fingertip was up to 0.1 N with the current limitation of 6 mA [11]. Recently, almost 2 N of additional friction force with 0.1-mA DC current was reported with the use of Johnsen-Rahbek effect [27]. However, the method still needs further investigation regarding its time response, since Johnsen-Rahbek effect seems dominant only in DC region.…”

This paper proposes a visuo-haptic feedback system that can provide haptic feedback to multiple users on an LCD monitor using electrostatic adhesion and built-in capacitive sensors. The prototype system consists of a 40-inch LCD monitor, an ITO electrode sheet arranged on the monitor, and multiple contact pads for electrostatic adhesion. By applying low-frequency haptic voltage and high-frequency sensing voltage to each pad, the system realizes passive haptic feedback, as well as position sensing using the same components. The passive haptic feedback force exceeds 1 N at 300 V rms. The performance of the sensing system is investigated in terms of interference, which shows the haptic voltage and existence of multiple pads can affect the sensing and can shift the output by a few millimeters. A pilot application, virtual hockey game, successfully demonstrates the sensing and haptic rendering capability of the proposed system. The effect of the interference on the demonstration is discussed.

“…The second category create haptic feedback through electroadhesion technique, which also use electrostatic force generated by DC excitation to the haptic surface. [9]. Both of these two classes of devices increase the friction between the fingertip and the interaction surface.…”

International audienceTactile devices with ultrasonic vibrations (based on squeeze film effect) using piezoelectric actuators are one of the existing haptic feedback technologies. In this study we have performed two psychophysical experiments on an ultrasonic haptic tablet, in order to find the minimum size of a tactile element on which all the users are able to perfectly identify different types of textures. Our results show that the spatial resolution of the tactile element on haptic touchscreen actually varies, depending on the number and types of tactile feedback information. A first experiment exhibits three different tactile textures, chosen as being easily recognized by users. We use these textures in a second experiment, and evaluate minimal spatial area on which the chosen set of textures can be recognized. Among other, we find the minimal size depends on the texture nature
