Embodiment 1

[0064] Embodiment 1, an active and intentional gesture detection device according to the embodiment of the present invention is characterized in that the detection device includes a myoelectric signal acquisition device, an EEG signal acquisition device, a brain muscle signal acquisition device and a brain muscle signal processing device .

[0065] The myoelectric signal acquisition device is used to acquire the operator's gesture myoelectric signal, and the gesture myoelectric signal includes: signals of extensor digitorum common, extensor pollicis brevis, flexor digitorum superficialis, and flexor carpi ulnaris. Such as figure 1 and 2 As shown, the myoelectric signal acquisition device includes several myoelectric electrodes arranged in a circular array on the forearm of the operator, four myoelectric electrodes are respectively arranged on each forearm, and the first myoelectric electrode is arranged at the extensor hallucis brevis. Electrode 1, the second myoelectric ele...

Embodiment 2

[0079] Embodiment 2, a method for detecting active intentional gestures according to the second embodiment of the present invention, such as Figure 6 As shown, the detection method includes:

[0080] Step 1, respectively set up the EMG signal acquisition device and the EEG signal acquisition device:

[0081] Four myoelectric electrodes are respectively arranged in a circular array at the extensor digitorum, extensor pollicis brevis, extensor carpi ulnaris and flexor carpi ulnaris of the operator's forearm to collect the operator's gesture myoelectric signals; figure 1 and 2 As shown, the first myoelectric electrode 1 is placed at the extensor hallucis brevis, the second myoelectric electrode 2 is placed at the common extensor muscle, the third myoelectric electrode 3 is placed at the flexor carpi ulnaris, and the third myoelectric electrode is placed at the superficial flexor muscle. Four EMG electrodes4.

[0082] Such as Figure 5 As shown, three claw-type dry electrodes...

Abstract

The invention discloses an active intentional gesture action detection device. The device comprises an electromyographic signal obtaining device, an electroencephalogram signal obtaining device, a brain muscle signal acquisition device and a brain muscle signal processing device, wherein the electromyographic signal obtaining device is used for obtaining a gesture action electromyographic signal of an operator, and comprises a plurality of electromyographic electrodes which are arranged on the forearms of the operator in a ring-shaped array manner; the electroencephalogram signal obtaining device is used for obtaining an electroencephalogram signal of the operator, and comprises three claw-type dry electrodes in a right ear lobe A2 area, a right forehead Fp2 area and a right vertex center C4 area; the brain muscle signal acquisition device is used for acquiring the gesture action electromyographic signal and the electroencephalogram signal; and the brain muscle signal processing device is used for processing the acquired gesture action electromyographic signal and electroencephalogram signal, and judging whether gesture action actions of the operator are intentional actions or unintentional actions, active actions or passive actions. The invention furthermore discloses an active intentional gesture action detection method. The active intentional gesture action detection device and method have the beneficial effects of detecting whether the operators have intentional subjective gestures and improving the reliability of gesture interaction control.

Description

technical field [0001] The present invention relates to the technical field of human-computer interaction, in particular to a detection device and detection method for active and intentional gestures. Background technique [0002] As a kind of human behavior, gestures are convenient, fast, rich in meaning, and easy to understand. It allows people to interact in a more natural and direct way in their daily lives. Therefore, the problem of how to use gestures to realize human-computer interaction has attracted more and more attention from researchers. [0003] Gesture recognition technology is a new type of natural human-computer interaction control technology based on advanced perception technology and computer pattern recognition technology. It can be divided into gesture recognition based on visual sensors and gesture recognition based on wearable sensors. Since the gesture recognition interactive system has the characteristics of easy installation, low cost and good user ...
