Ultrasonic Virtual Button Registration System

The patent replaces the mechanical contact-based registration system with an ultrasonic field-based interaction system. Users interact with virtual buttons formed by ultrasonic signals in space, eliminating the need for physical contact with registration devices. This substitution of mechanical interaction with acoustic field interaction simultaneously improves registration efficiency and eliminates infectious disease transmission risk.

The patent introduces ultrasonic signals as an intermediary medium between the user and the registration system. The ultrasonic transducer array generates ultrasonic signals that form virtual buttons in space, serving as an intermediary that enables user interaction without direct contact. This intermediary approach allows efficient registration operations while preventing pathogen transmission through contact.

The patent transitions the interaction from a two-dimensional physical device surface to a three-dimensional spatial ultrasonic field. Virtual buttons are formed in three-dimensional space through ultrasonic signal focusing, allowing users to interact by gesturing toward specific spatial locations. This dimensional change enables self-service registration functionality while eliminating contact with physical devices, thereby preventing infectious disease spread.

The patent creates virtual copies of physical buttons in the form of ultrasonic signal fields. Instead of physical buttons on a device surface, the system generates virtual button representations through focused ultrasonic signals in space. These virtual copies provide the same operational functionality as physical buttons but without the contact-related infection risk.
