Abstract

The invention discloses a gesture input device and method for computer characters based on electromyographic signals. The problems that existing gesture input devices and methods have strict externalconditions and inconvenience are solved. The device comprises an arm ring unit and an execution unit; the arm ring unit comprises a left arm ring body and a right arm ring body which are worn on the left arm and the right arm respectively; the left arm ring body comprises a left surface electromyographic signal collection unit, a left control unit and a left sending unit, and the right arm ring body comprises a right surface electromyographic signal collection unit, a right control unit and a right sending unit; the left surface electromyographic signal collection unit, the left control unit and the left sending unit are in wired connection in sequence; the right surface electromyographic signal collection unit, the right control unit and the right sending unit are in wired connection in sequence; the execution unit comprises a receiving unit, a processor and a displayer; the receiving unit, the processor and the displayer are in wired connection in sequence; the arm ring unit is wirelessly connected with the execution unit. The invention further provides the gesture input method for the computer characters based on the electromyographic signals.

Description

technical field [0001] The invention relates to a method and a device in the field of surface electromyography signal processing, more precisely, the invention relates to a device and a method for inputting computer characters by gesture based on an electromyography signal. Background technique [0002] The keyboard and the mouse are the input devices of common electronic devices at present, and the operation of the electronic device is mainly realized by operating the keyboard or the mouse to move the cursor and input single-click and double-click commands. However, conventional input devices such as keyboards, touchpads, and mice require physical devices during operation, which is not convenient. [0003] In recent years, a gesture input device has appeared, through which a user can perform operations such as moving a cursor to select an item on the screen or moving the item itself on the screen through intuitive input of hand movements. That is, the user moves the cursor...
