The generation of human body positive action, by brain control realization, is dispersed with neuron and meat fiber from brain to parts of body
Tissue.Action message between brain and limbs is to send the signal of telecommunication by the nervous system of brain to motor neuron to transmit
, after the signal of telecommunication that neuron receives, it is that peripherad meat fiber transmits the corresponding signal of telecommunication equally, promotes muscle fine
Dimension produces certain contraction, and the nervous system of people can detect the contraction state of meat fiber in real time at this moment, and then to action
Signal is adjusted.When human body produces different action, the contraction state of muscle also can difference, produced muscle electricity
Stream signal is also discrepant.
When the finger of user has action, the muscle of corresponding the back of the hand can produce variation, thus produces faint and band finger
The electromyographic signal of motion characteristic.Palm is when space motion, and this utility model is worn on the motion sensor of the back of the hand along with palm
Motion, it is possible to transmitting out by the information of the attitude of reaction palm motion in real time, two kinds of signals are through a series of circuit pretreatment
After enter into carry out inside real-time signal processor data fusion and differentiate output, obtain corresponding gesture instruction, then pass through nothing
Line mode is sent to controlled plant.
This utility model has the advantages that
(1) equipment of the present utility model is the electromyographic signal by detection the back of the hand and the motion sensor senses utilizing the back of the hand
Palm moving situation realizes gesture and differentiates, the method belonging to non-intrusion type, and comparing, (probe inserts muscle to medically intrusive mood
Inside realize high-precision electromyographic signal collection) mode, having does not has that wound, volume be little, low in energy consumption, easy to use, portability
The advantage such as good.
(2) this utility model ingenious application modern biotechnology electronic technology, propose and achieve a kind of novel concept, efficiently,
Directly, man-machine interaction mode that degree of freedom is high, compensate for the limitation such as non-natural of conventional human's interactive mode.This utility model
Myoelectricity and motion detection device be worn on the back of the hand, equipment is small and exquisite, stable, use do not limited by environment, it is possible to for making
User provides mode of operation and more stable operating effect more freely.
(3) this equipment is in implementation process, and employing Comfortable elastic material is as the wearing of media implementation equipment, functionally
It is capable of, and replaces existing mouse function to a certain extent, be provided simultaneously with more superior Consumer's Experience.

Detailed description of the invention
Below by accompanying drawing and application example, the technical solution of the utility model is described in detail further.
This utility model equipment wearing mode displaying figure on the back of the hand is as it is shown in figure 1, this gesture discriminating device includes setting
Standby main body 1 and fixing hand strap 2, be respectively adopted elastic cotton and make, to improve the wearing comfort degree of user and to ensure that electrode can be with
Skin of dorsum of hand contact is good.Selecting the back of the hand position, the action being because each finger can drive the corresponding muscle of the back of the hand to produce
The strongest contractile response.
As in figure 2 it is shown, equipment body 1 includes the electrode 3 gathering electromyographic signal, Real-time digital signal processing device 4, myoelectricity mould
Intend signal acquisition circuit 5, motion-sensing circuit 6 and radio transmitter 7.The electrode 3 gathering electromyographic signal is placed in the back of the hand
Center, three electrode tips present 30 degree of isosceles triangles and place, and signal is with reference to common port 3-3 in centre, and two difference are defeated
The straight line entering electrode 3-1 with 3-2 composition is vertical with finger orientation such that it is able to improve the discrimination precision of gesture motion.Electrode 3 is adopted
Using circular electric pole piece, under conditions of device structure allows, electrode slice area is big as far as possible, at a distance of as far as possible.
Equipment uses a road difference electromyographic signal collection electrode from skin of dorsum of hand acquisition surface electromyographic signal.From know-why
For on, Differential Input passage is the most, and the precision of gesture identification is the highest, but can bring the cost of system, power consumption, complexity
Increase.The electromyographic signal that electrode 3 gathers from the back of the hand, between 1uV to 1mV, is amplified place by amplifying circuit of analog signal
Reason.Initial data owing to gathering is mingled with more noise signal, such as the power frequency component of the 50/60Hz in air, therefore amplifies
After analogue signal carry out noise remove through analogue signal filter circuit, furthermore it is also possible at Real-time digital signal processing device 4
The inside is also provided with digital filter extraction further to signal.Signal is finally to carry out processing fortune with the form of digital signal
Calculating, so filtered signal enters analog to digital conversion circuit and is digitally converted, the signal after conversion enters into real-time digital
Signal processor 4 processes.
During electromyographic signal collection, motion-sensing signal also is acquired processing in synchronization.Motion-sensing signal
It is to be acquired by motion-sensing circuit 6, is then transferred to radio transmitter 7.The motion that radio transmitter 7 will collect
Sensing data sends to and Real-time digital signal processing device 4, Real-time digital signal processing device 4 by merge electromyographic signal data with
And motion-sensing data, contrast according to the characteristic information in gesture information storehouse and resolve, differentiate out by gesture feature, and make corresponding
Machine instruction mappings work, the machine instruction mapped the most at last is transferred to radio transmitter 7, and radio transmitter 7 passes again
It is defeated by controlled plant, it is achieved the purpose of control.Power drives is provided by rechargeable battery during the operation of whole system, chargeable
Battery is to be charged by electric power management circuit.
Fig. 4 illustrates gesture identification equipment of the present utility model and applies the example on user's PC 8.In example, this sets
For replacing mouse, it is achieved the movement of computer pointer, single hit and dblclick operation.Thus extending, this equipment can also realize toy
The somatosensory operation etc. controlling, playing.
Fig. 5 illustrates this utility model gesture identification equipment and applies the example at VR equipment 9.In example, gesture identification sets
For coordinating VR equipment 9, it is achieved the experience sense of user's augmented reality as the body-sensing input equipment of user.Gesture identification sets
It is to carry out communication by wireless transmission method between standby main body 1 and VR equipment 9.
