Description
Technical field
The utility model is related to a kind of action extraction class wearable devices, and in particular to a kind of wearable signal processing
And device talk unit module.
Background technology
Wearable device directly wears or is integrated into the clothes of user or a kind of portable device of accessory.
Wearable device is not only a kind of hardware device, even more strong to realize by software support and data interaction, high in the clouds interaction
Big function, wearable device will bring very big transformation to our life, perception.
Electromagnetic type motion capture system is more commonly used motion capture device.Generally by emission source, receiving sensor and
Data processing unit forms.Emission source generates the electromagnetic field by the distribution of certain time and space idea in space；Receiving sensor is placed in
The key position of actor body as the action of performing artist moves in electromagnetic field, passes through cable or wireless mode and data
Processing unit is connected.When performing artist acts in electromagnetic field, receiving sensor sends the signal received to place by cable
Unit is managed, the spatial position and direction of each sensor can be calculated according to these signals.Polhemus companies and
Ascension companies are famous to produce electromagnetic type motion capture device.For some high-speed motions, such as boxing, basketball ratio
Match etc., which is not met by requiring.What the advantages of electromagnetic type is motion-captured first consisted in its record is sextuple information,
Spatial position can not only be obtained, moreover it is possible to obtain directional information, this point is very valuable to some special application scenarios.Secondly
It is that speed is fast, real-time is good, and when performing artist performs, the actor model in animation system can be with simultaneous reactions, convenient for rehearsing, adjusting
And modification.
Electromagnetic field analysis mode is divided into two classes, and the first kind is combined using D.C. magnetic field with alternating electric field generates nutating field
Mode, this mode is due to the use of DC static field, it is easy to be disturbed be subject to metal in measured zone；Second class is using complicated
3 to orthogonal 3 frequency antenna sets receive-transmit system, by transmitting 3 to each one frequency of spontaneous emission of orthogonal antenna group signal, receive
End solves the position in three reference axis respectively also using 3 to orthogonal antenna individual reception, calculate reception antenna on the whole with hair
Penetrate the distance and angle of antenna.The system rejection to disturbance ability is stronger but complicated, and calculating parameter extraction is complicated, and price is very
Costliness generally requires 100,000 or hundreds thousand of, it is impossible to be used in common recreational use.This two classes mode all has there are one common ground,
Transmitting antenna is positioned over some position independently of people is tracked, and reception antenna is placed on as beacon is tracked human body everywhere.
So user's ratio must be in transmitting antenna placement location a certain range, it is impossible at will mobile.Actual product such as bohr west is not
The product line of this company.
Existing action extraction class wearable device is generally connected by the way of cable connection with other sensors,
Shortcoming is bulky, it is impossible to is connected with the interface of clothes, cluster structure that can only be mating with itself is connected cannot be independent
It removes, corresponding the whole series sensor and clothes are independent, it is impossible to wash, it is impossible to which directly fixed with clothes, wearing is very troublesome.
