Embodiment Construction

[0025] The invention relates to a method for realizing the function control of mouse button clicking and mouse cursor movement by using electromyographic signals.

[0026] Teeth clenching actions of different positions, intensities, and durations will cause the temporal muscles to produce EMG signals with different characteristics. The present invention converts them into computer-recognizable mouse control signals through collection, processing and calculation.

[0027] The EMG signals generated by the temporal muscles on the left and right sides of the head are selected for acquisition, processing and calculation to convert them into control signals, and the functions of mouse button click and mouse cursor movement are realized through different combinations of dual-channel control signals.

[0028] The functions of mouse button click and mouse cursor movement are only controlled by the electromyographic signal of the position of the head temporal muscle when the teeth are clenched....

Abstract

The invention provides a method for realizing control of mouse button clicking and mouse cursor moving functions by using head surface electromyogram signals. Biting actions at different positions, strengths and lasting times generate electromyogram signals with different characteristics; when the biting actions are carried out, the electromyogram signals at the head temporalis are acquired and processed and then converted to control signals which can realize mouse button clicking and mouse cursor moving functions and are connected with a computer via a wireless technology, so that patients with upper extremity motion function disorders such as high-level paraplegia and upper limb amputation can realize the control to a computer mouse through the simple biting actions.

Description

Technical field [0001] The invention relates to a method for realizing the function control of mouse button clicking and mouse cursor movement by using electromyographic signals, and belongs to the field of rehabilitation engineering and computer technology. Background technique [0002] The mouse is an indispensable input device for a computer. Current products are mainly controlled by the movement and click of the hand, and cannot meet the needs of patients with high paraplegia and upper limb disabilities. [0003] In recent years, human-computer interaction technology based on bioelectrical signals such as brain electricity, eye electricity, and myoelectricity has become one of the frontiers and hotspots of teleoperation robots and human-computer interaction technology. A large number of studies have shown that the extraction of EEG and EOG signals is not convenient enough, and it is susceptible to personal misoperations and surrounding environmental factors, and the cost of EEG...
