Embodiment
Poor in order to solve the precision existed when gesture identification in prior art, and the problem that comfort and convenience are also poor, inventor is studied gesture identification scheme of the prior art, and proposes a kind of gesture identification scheme.This technical scheme is different from the scheme of data glove, does not require that user dresses special gloves, but utilizes multiple pressure transducer measure the force value of wrist ligament place diverse location thus identify different gesture-type; Solve uncomfortable and inconvenient problem when dressing data glove on the one hand, pressure transducer is different from image taking completely on the other hand, it is neither by the impact of sharpness, illumination and algorithm, and also there is not the restriction of shooting angle, the precision therefore measured also improves greatly.
Below in conjunction with Figure of description, embodiments of the invention are described, should be appreciated that embodiment described herein is only for instruction and explanation of the present invention, is not limited to the present invention.And when not conflicting, the embodiment in this explanation and the feature of embodiment can be combined with each other.
The major part motion pointed in human palm is all rely on the muscle being positioned at forearm, and these muscle are connected with finger by ligament, and these ligaments all collect via wrist place, then extend to the diverse location of palm.When palm is in different conditions, when namely finger is in different degree of crook, the tensile relationship of these ligaments is also different.Therefore, if the force value of the different ligaments under can obtaining different gesture, just can carry out according to these force value obtained calculating and determining corresponding gesture-type.
Based on above-mentioned design, embodiments provide a kind of gesture identification method, as shown in Figure 1, be the realization flow figure of the method, mainly comprise the steps:
Step 11, carries out pressure detection by the diverse location of multiple pressure transducer to wrist ligament place, obtains the force value set be made up of the force value of the diverse location at wrist ligament place;
Wherein, each pressure transducer all can measure the pressure change in particular range, and the quantity of pressure transducer can sets itself according to the actual requirements.
Step 12, according to the corresponding relation that the force value set pre-set and gesture identify, determines that the gesture corresponding with the force value set obtained identifies;
Wherein, each gesture mark characterizes a kind of gesture, and its structure and coded system can be arranged voluntarily.
Step 13, the information gesture determined being identified the gesture characterized exports.
Based on above-mentioned principle, the embodiment of the present invention provides a kind of gesture identifying device, is illustrated in figure 2 the structural representation of this device, and this device forms primarily of four parts:
Storer 21, processor 22, controller 23 and multiple pressure transducer 24, wherein:
Multiple pressure transducer 24, for carrying out pressure detection to the diverse location at wrist ligament place, obtains the force value of the diverse location at wrist ligament place;
Storer 21, for prestoring the corresponding relation that force value set and gesture identify;
Wherein, the each gesture mark prestored in storer 21 characterizes a kind of gesture, its structure and coded system can be arranged voluntarily, and the force value set of each gesture mark correspondence is combined by the force value of the diverse location of wrist ligament, and the force value of the diverse location at wrist ligament place can be undertaken detecting determining by equipment such as pressure transducers in advance.
Processor 22, for the force value of the diverse location at wrist ligament place obtained according to multiple pressure transducer 24, obtains force value set; And according to the above-mentioned corresponding relation prestored in storer 21, determine that the gesture corresponding with the force value set obtained identifies;
Wherein, processor 22, when obtaining force value set, can adopt the mode of poll, obtains the force value of the diverse location of wrist ligament, and then determine force value set from multiple pressure transducer 24.
Controller 23, the information that the gesture for being determined by processor 22 identifies the gesture characterized exports to follow-up application apparatus, such as moves the application apparatus of the contents such as dynamic posture conversion for the personage realized in computer game.
Wherein, use this device for the convenience of the users, multiple pressure transducer 24 can be arranged on can be fixed on user's wrist ligament place para tape on, in order to the accuracy of the comfort and measurement data that ensure this para tape, this para tape can for having flexible ring texture.As shown in Figure 3, for multiple pressure transducer 24 being made the use schematic diagram of a pressure bracelet, this pressure bracelet is worn on user's wrist ligament place, when reality uses, should select the bandage that elastic force is larger, can feel tight being advisable with wrist ligament place.And miscellaneous part, such as storer 21, processor 22 and controller 23 can be built in this pressure bracelet, also respectively as independently parts, can set up data path by wireless or wired mode and pressure bracelet.
The pressure change in particular range all can be measured due to each pressure transducer 24, therefore this multiple pressure transducer 24 can along rectangular array on para tape, as shown in Figure 4, for the structural representation of the multiple pressure transducers 24 along rectangular array, with reference to figure 4, its by m × n pressure transducer 24 along rectangular array, forming a dimension is the sensor matrices of m × n, the scale of this rectangular array can accuracy of detection optionally and determining, in general, its dimension should be not less than 10 × 10.
When multiple pressure transducer 24 is along rectangular array, the force value of the diverse location at the wrist ligament place obtained according to multiple pressure transducer 24 and force value set determined is force value matrix, and the dimension of rectangular array should be identical with the dimension of this force value matrix.
After having worn pressure bracelet, when user has gesture to change, pressure transducer 24 in bracelet just can detect the force value of wrist ligament place diverse location, and processor 22 can adopt the mode of poll, the force value of wrist ligament diverse location is obtained respectively from multiple pressure transducer 24, determine force value matrix, and according to the corresponding relation that the force value matrix prestored in storer 21 and gesture identify, the gesture that the force value matrix retrieved and determine is corresponding identifies, concrete searching algorithm can adopt common highly effective algorithm, in the embodiment of the present invention, this is not restricted, finally by controller 23, the gesture determined in processor 22 mark is exported to follow-up application apparatus.
