Modern telecommunication systems require the communication of non-verbal information with a goal for more effective communications. Transfer of touch sensations is called tactile broadcasting. First of all, the article describes the features of generation in air using focused ultrasound radiation pressure that creates a force action on an obstacle and causes a person tactile sensation. Moreover, there is an example of calculation of the radiation pressure for disc matrix transmitter in this article. Lastly, the dependence of focused ultrasound field characteristics and radiation pressure on the angle of the spatial scan was investigated.
