Abstract
Resent researches show a wide application possibility of our product which produces tactile stimulation from a distance by utilizing airborne ultrasound, named as "airborne ultrasound tactile display." In this paper, a portable device of the tactile display is introduced. It is expected that more people can use it easily for wider variety of applications. The size of the device is 19x19x5 cm^3. 285 ultrasound transducers are used. In order to estimate the output force of the device, a simple model is developed and the output force is estimated to be 14 mN.
