■ Dr. Hoshi's Chapters
(1) Hoshi, T. (2022). Introduction to Ultrasonic Mid-Air Haptic Effects
https://doi.org/10.1007/978-3-031-04043-6_1
[Outline] The basic principles of ultrasound mid-air haptics - acoustic radiation pressure, phased array, vibrotactile stimulation, and audible sound generation - are explained assuming a simplified situation.

https://doi.org/10.1007/978-3-031-04043-6_17
[Outline] The tolerance sound pressure level is discussed based on previous reports on the effects of high-intensity ultrasonic waves on the human body, and the optimal safety distance is determined based on nonlinear absorption.

Takayuki Hoshi received a Ph.D (Information Science and Technology) from the University of Tokyo in 2008. After working as JSPS Research Fellowship for Young Scientists DC2/PD (2007-2009), assistant professor at Kumamoto University (2009-2011), Nagoya Institute of Technology (2011-2016), and the University of Tokyo (2016-2017), he founded Pixie Dust Technologies, Inc. in 2017. He is an expert of wave control technology based on full use of physics and mathematics. He is currently working on social implementation of wave control technology through industry-academia collaboration and open innovation.
