“…Here, the tactile sensations are of low fidelity as the area of stimulation is large and there is a latency to producing the air vortices in a specific location. Air jets have also been used, but these lack accuracy and are difficult to control [Suzuki and Kobayashi 2005]. A method which has a higher fidelity is using ultrasound-based acoustic radiation forces [Hoshi et al 2010;Alexander et al 2011;Carter et al 2013], which produces multiple individually perceivable points of 1 cm diameter in mid-air.…”

AbstractWe present a method for creating three-dimensional haptic shapes in mid-air using focused ultrasound. This approach applies the principles of acoustic radiation force, whereby the non-linear effects of sound produce forces on the skin which are strong enough to generate tactile sensations. This mid-air haptic feedback eliminates the need for any attachment of actuators or contact with physical devices. The user perceives a discernible haptic shape when the corresponding acoustic interference pattern is generated above a precisely controlled two-dimensional phased array of ultrasound transducers. In this paper, we outline our algorithm for controlling the volumetric distribution of the acoustic radiation force field in the form of a three-dimensional shape. We demonstrate how we create this acoustic radiation force field and how we interact with it. We then describe our implementation of the system and provide evidence from both visual and technical evaluations of its ability to render different shapes. We conclude with a subjective user evaluation to examine users' performance for different shapes.

“…Research has shown that this can be achieved using air jets [Suzuki and Kobayashi 2005], air vortices [Sodhi et al 2013], and ultrasound [Carter et al 2013;Hoshi et al 2010]. Among these three, we have identified ultrasound as the most flexible and dynamic method for producing volumetric haptic shapes.…”

“…Suzuki and Kobayashi developed a force feedback interface where air nozzles are mounted inside of a table, and the user holds an "air receiver", a cup-shaped object. By optically tracking the object, the system controls the air output from the table such that different jets create various forces as the ejected air interacts with the cup [10].…”

Almost all commercially available haptic interfaces share a common pitfall, a small shoebox-sized workspace; these devices typically rely on rigid-link manipulator design concepts. In this paper we outline our design for a new kinesthetic haptic system that drastically increases the usable haptic workspace. We present a proof-ofconcept prototype, along with our analysis of its capabilities. Our design uses optical tracking to sense the position of the device, and air jet actuation to generate forces. By combining these two technologies, we are able to detach our device from the ground, thus sidestepping many problems that have plagued traditional haptic devices including workspace size, friction, and inertia. We show that optical tracking and air jet actuation successfully enable kinesthetic haptic interaction with virtual environments. Given an appropriately large volume high-pressure air source, and a reasonably high speed tracking system, this design paradigm has many desirable qualities when compared to traditional haptic design schemes.
