Gesture sensor

Abstract

The invention discloses a gesture sensor, which comprises a myoelectricity dry electrode, a myoelectricity signal conditioning module, a microprocessor, an IMU (Inertial Measurement Unit), a touch vibration module, a power supply module and a Bluetooth module, wherein the gesture sensor can be worn on the muscle belly part of the front arm of the left hand or the right hand of an operator; throughthe myoelectricity dry electrode, the myoelectricity signal of the front arm is collected and is sent to the myoelectricity signal conditioning module; through the IMU, the motion data of the front arm is collected, is converted into a digital signal through A / D and is subjected to filtering preprocessing; the digital signal is sent to an upper computer or other intelligent terminals through a Bluetooth module; and the myoelectricity signal and the IMU data are subjected to fusion processing to judge the gesture made by the operator at present. The gesture sensor can be applied to a human-computer interaction system of gesture sensing and control, is convenient in operation and is high in experience feeling.

Description

technical field [0001] The present invention relates to a gesture sensor, in particular to a gesture sensor that combines surface myoelectricity to sense finger movements and an IMU to sense arm motion. Background technique [0002] At present, in the field of gesture perception and control, most products rely on cameras or a large number of other hardware to recognize gestures. Such products are not only heavy, expensive, and visually cumbersome, but also have restrictions on the use environment. Promote use in daily life. Contents of the invention [0003] In view of the above deficiencies, the present invention provides a gesture sensor, which can be worn on the muscle belly of the forearm of the operator's left or right hand. Collect signals and accurately recognize the operator's gestures, such as moving up, down, left, right of the arm, fisting, opening, swinging left, swinging right of the fingers and their combinations, used to control computers and smart phones ...
