“…This technology allows users to perceive tactile sensation even in the absence of physical objects. Based on this approach, Monnai et al proposed a system to interact with floating images, using not only visual feedback (through light beams), but also mid-air haptic feedback through ultrasound in order to create the sensation of touching a virtual screen [41]. In a more recent work, Makino et al introduced a system to clone real objects into virtual ones.…”

Touchless interfaces allow users to view, control and manipulate digital content without physically touching an interface. They are being explored in a wide range of application scenarios from medical surgery to car dashboard controllers. One aspect of touchless interaction that has not been explored to date is the Sense of Agency (SoA). The SoA refers to the subjective experience of voluntary control over actions in the external world. In this paper, we investigated the SoA in touchless systems using the intentional binding paradigm. We first compare touchless systems with physical interactions and then augmented different types of haptic feedback to explore how different outcome modalities influence users' SoA.From our experiments, we demonstrated that an intentional binding effect is observed in both physical and touchless interactions with no statistical difference. Additionally, we found that haptic and auditory feedback help to increase SoA compared with visual feedback in touchless interfaces. We discuss these findings and identify design opportunities that take agency into consideration.

“…With new technologies that can focus airborne ultrasound the hands and fingers do not need to be equipped with physical actuators to perceive in-air haptic sensations [6,25]. The ultrasound beams can pass through a perforated sheet or a loosely woven fabric used as display surface for topprojection [6], and can be redirected by a specular reflector towards the target [25].…”

“…The ultrasound beams can pass through a perforated sheet or a loosely woven fabric used as display surface for topprojection [6], and can be redirected by a specular reflector towards the target [25]. However, the sensation can be perceived only when the hands are 15-20 cm away from the transmitter array due to the distance needed to focus the beams.…”

“…Unlike focused airborne ultrasound [6,25], SPARKLE enables a shorter working distance and creates sharper sensations suitable for hover interactions. Recently, body-carried electrostatic charge was proposed for mobile scenarios to give users a controlled electric shock when touching a conductive object, or to exert force onto lightweight particles (e.g., sand) very near to the fingertip [26].…”

Many finger sensing input devices now support proximity input, enabling users to perform in-air gestures. While nearsurface interactions increase the input vocabulary, they lack tactile feedback, making it hard for users to perform gestures or to know when the interaction takes place. Sparkle stimulates the fingertip with touchable electric arcs above a hover sensing device to give users in-air tactile or thermal feedback, sharper and more feelable than acoustic mid-air haptic devices. We present the design of a high voltage resonant transformer with a low-loss soft ferrite core and self-tuning driver circuit, with which we create electric arcs 6 mm in length, and combine this technology with infrared proximity sensing in two proof-of-concept devices with form factor and functionality similar to a button and a touchpad. We provide design guidelines for Sparkle devices and examples of stimuli in application scenarios, and report the results of a user study on the perceived sensations. Sparkle is the first step towards providing a new type of hover feedback, and it does not require users to wear tactile stimulators.

“…Proposed solutions can be broadly divided in two groups: tactile or haptic representations ( [Kurze 1996;Xu et al 2011;Bernareggi et al 2008;Monnai et al 2014;Kim and Lim 2011]) and image sonification. The focus of this review is on the latter group, with particular attention to the techniques that can be adopted to recognize shapes on touchscreen devices.…”

There are several situations in which a person with visual impairment or blindness needs to extract information from an image. For example, graphical representations are often used in education, in particular in STEM subjects. In this contribution we propose a set of 6 sonification techniques to support individuals with visual impairment or blindness in recognizing shapes on touchscreen devices. These techniques are compared among themselves and with 2 other sonification techniques already proposed in the literature. Using Invisible Puzzle, a mobile application which allows to conduct non-supervised evaluation sessions, we conducted tests with 49 subjects with visual impairment and blindness, and 178 sighted subjects. All subjects involved in the process successfully completed the evaluation session, showing high level of engagement, demonstrating therefore the effectiveness of the evaluation procedure. Results give interesting insights into the differences among the sonification techniques and, most importantly, show that after a short training subjects are able to successfully identify several different shapes.
