Embodiment
Present inventor finds through research; because prior art is usually based on the algorithm realization environment calibration of static calibration; not based on environment calibration and the environment dynamic calibration of power up; the interference of environmental factor to gesture identification could not be eliminated completely, cause the accuracy of gesture identification and reliability low.
For this reason, in the present invention, by gathering the sensed data of power up and the rear inductive disks that powered on, the area of sensed data and inductive disks is carried out scale operation, obtain environment static sensed data and the dynamic sensed data of environment, the sensed data of complementary induction dish, elimination power up and environmental factor, on the impact of inductive disks, improve accuracy and the reliability of gesture identification environment calibration.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the inductive disks of a kind of gesture identifying device of the embodiment of the present invention.
In the gesture identifying device of the embodiment of the present invention, adopt 5 inductive disks, be respectively inductive disks 3011, inductive disks 3012, inductive disks 3013, inductive disks 3014 and inductive disks 3015, operate for gesture operation parts (not shown), thus generation sensed data, described sensed data forms gesture identification matrix, according to position and the described gesture identification matrix of described inductive disks, to analyze the movement locus of described gesture operation parts.
Usually, described gesture operation parts can be fingers, also can be any parts that can operate on gesture identifying device of finger operable, as manipulation pen etc.Corresponding discrimination bit D1, discrimination bit D2, discrimination bit D3, discrimination bit D4 and discrimination bit D5 are arranged respectively for inductive disks 3011, inductive disks 3012, inductive disks 3013, inductive disks 3014 and inductive disks 3015.
In concrete enforcement, described five inductive disks 3011,3012,3013,3014 and 3015 can be embedded in surface-mounted integrated circuit (not shown), and the integrated circuit in the surface-mounted integrated circuit region that inductive disks is corresponding is for gathering the sensed data of described inductive disks.
Operationally, above inductive disks, the environmental factor such as temperature and humidity of coverture, environment also can produce sensed data in inductive disks, and also can produce sensed data due to the impact of the various factors such as the design of circuit and voltage and current in inductive disks in power up.
Factor in described environmental factor or power up has an impact to one of them of described metal inductive disks, cause metal inductive disks to produce electric capacity with the electrode in corresponding integrated circuit region, the magnitude of voltage that described electric capacity causes exports as sensed data by integrated circuit.Described sensed data is the quantized value that the factor in described environmental factor or power up affects described metal inductive disks 3011,3012,3013,3014 and/or 3015.
Therefore, be necessary to carry out environment calibration, with promote final gesture identification operation time accuracy and reliability.
Be understandable that, described gesture identifying device can in the inductive disks of different azimuth configuration varying numbers, and realize the identification of gesture, the embodiment of the present invention does not limit this.
Fig. 2 is a kind of environment static calibration steps of the present invention process flow diagram, and described environment static calibration steps can be used for described gesture identifying device, such as, gesture identifying device shown in Fig. 1.
