“…With the use of ferrofluid and electro-magnets, the system can support instantaneous motion. Cross-Field Haptics [ 33 ] proposes a new method of drawing haptic sensations using ferrofluids and electrostatic fields. It reproduces the haptic sensation of a projected texture using the flexibility of ferrofluid and the resistance force of electrostatic adsorption caused by an electric field.…”

Recently, remote meetings and work-from-home have become more common, reducing the opportunities for face-to-face communication. To facilitate communication among remote workers, researchers have focused on virtual space technology and spatial augmented reality technology. Although these technologies can enhance immersiveness in collaborative work, they face the challenge of fostering a sense of physical contact. In this work, we aimed to foster a sense of presence through haptic stimulation using pneumatic actuators. Specifically, we developed a choker-type wearable device that presents various pressure patterns around the neck; the pattern presented depends on the message the device must convey. Various combinations of haptic presentation are achieved by pumping air to the multiple pneumatic actuators attached to the choker. In addition, we conducted experiments involving actuators of different shapes to optimize the haptic presentation. When linked with a smartphone, the proposed device can present pressure patterns to indicate incoming calls and notifications, to give warning about an obstacle that one who is texting might miss while walking, and to provide direction to a pedestrian. Furthermore, the device can be used in a wide range of applications, from those necessary in daily living to those that enhance one’s experience in the realm of entertainment. For example, haptic feedback that synchronizes with the presence of a singer or with the rhythm of a song one listens to or with a performer’s movements during a stage performance will immerse users in an enjoyable experience.

In this paper, a method of rendering aerial haptics that uses an aerodynamic vortex and focused ultrasound is presented. Significant research has been conducted on haptic applications based on multiple phenomena such as magnetic and electric fields, focused ultrasound, and laser plasma. By combining multiple physical quantities; the resolution, distance, and magnitude of force are enhanced. To combine multiple tactile technologies, basic experiments on resolution and discrimination threshold are required. Separate user studies were conducted using aerodynamic and ultrasonic haptics. Moreover, the perception of their superposition, in addition to their resolution, was tested. Although these fields cause no direct interference, the system enables the simultaneous perception of the tactile feedback of both stimuli. The results of this study are expected to contribute to expanding the expression of aerial haptic displays based on several principles.

“…The other is mid-air haptic interface that enables both direct-touch and mid-air interaction, without the direct contact with the human. The way to render texture feedback on a touchscreen is that uses electrovibration to representing the change in friction [24], or utilizes magnetorheological fluid (MRF) which is flexible liquid affected by the magnetic field, and electrovibration on a film that covers MRF to generate adsorption force from the electrostatic field [4]. Active surfaces that try to literally re-create the object that is being touched are a brute-force approach to haptic display.…”

In recent years, Advances in the 3D print technology show us a way to customize almost anything we want. In this paper, we provide a rapid fabrication method to create personalized pneumatic haptic displays using the 3D printing technology. Based on the miniature airbags, the haptic display is light to wear, waterproof, and low-cost. Because it is free to customize, various shapes even ungrounded(wearable) haptic displays or grounded haptic displays can be made out of. Each airbag is inflated by a full-range speaker which mounted on a closed air chamber where the air is transferred back and forth through a tiny nozzle to the airbag. So both low-frequency pressure and high-frequency vibration could be presented. As a haptic display, the performance on rendering tactile sensation of the airbag was evaluated, also the psychophysical experiment was down for measuring the capability of rendering multi-dimensional tactile sensation. As the result, the airbag is able to present mechanical vibrations with a range of 2Hz to 800Hz, and to render directional tactile information which is correctly distinguished over 80%.
