    ABSTRACT: This paper describes a new tactile device which produces stress fields in 3D space. Combined with mid-air and/or 3D stereoscopic displays, this device provides high-fidelity tactile feedback for interaction with visual objects. The principle is based on a nonlinear phenomenon of ultrasound; acoustic radiation pressure. The fabricated prototype device consists of 324 airborne ultrasound transducers, and the phase and intensity of each transducer are controlled individually. The total output force within the focal region is 1.6 gf. The spatial resolution is 20 mm. The prototype can produce sufficient vibrations up to 1 kHz. An interaction system including the prototype is also introduced which tracks user's hand and provides suitable touch feeling.

    ABSTRACT: In this paper, a hologram with tactile reactions is presented. The developed system consists of three components; a holographic display, a hand tracker, and a tactile display. The tactile display, which is our original device, produces force on user's bare hand without any contact by using radiation pressure of airborne ultrasound. It adds the sense of touch to optical images floating in mid-air. In order to represent the feeling of impact, some improvements are added to the tactile display. As a result, the tactile display has an ability to produce up to 4.8 gf without air flow.

    ABSTRACT: For designing a simple and more realistic haptic feedback system, we propose integrating an underactuated mechanism with one-point kinesthetic feedback from the arm with multipoint tactile feedback. By focusing on the division of roles between the cutaneous sensation in fingers and the proprioception in the arm. We have implemented a prototype system that provides kinesthetic feedback to the arm and tactile feedback to the fingers, examined the difference of weight recognition according to the applied point of kinesthetic feedback, and confirmed the effectiveness of the proposed method.
