▎ 摘　　要

NOVELTY - The system has an action collecting module (3) adhered to a mouth of user and for converting lip actions into continuous changes of resistance. A signal processing module (4) is placed in an ear muff of a headset base body (1). A Bluetooth transmission module (6) is fixed on a side of the ear muff, and transmits resistance data to a computer, and is matched with instruction data stored in a database (5) after fitting, and sends a fitting result to a target machine (7) to control the target machine to perform corresponding actions. A single chip microcomputer is electrically connected with a laser-induced graphene-polyvinylidene fluoride copolymer dual-mode pressure sensor. The database is connected with the signal processing module through the Bluetooth transmission module. USE - Human-computer interaction system for use in a noisy working environment and an all-weather and multi-environment. ADVANTAGE - The system can be applied to the noisy working environment, thus improving accuracy of control. The system realizes use of the all-weather and multi-environment. The Bluetooth transmission module is placed in the ear muff, thus releasing hands and improving working efficiency. The pressure sensor is designed to S-shape so as to improve muscle stretching direction of action of an electric signal. The database is generated by machine learning. The system allows user for wearing the sensor, and obtains data during speaking and gradually stores the data in the database at same time, thus continuously learning and accumulating the user in using process, continuously expanding the database, and improving identification precision.
