Problems solved by technology

[0002] The traditional operation technology is usually based on the mouse and keyboard, the input method is limited, and it is impossible to achieve smooth intermediate state operation, and it is difficult to realize accurate painting art, driving technology, cooking technology and other operations. However, the main idea of ​​the existing technical solutions is to add sensing components for each finger, so as to realize the posture collection of the whole hand, resulting in a complex structure during product manufacturing, and the existing technology ignores human The middle finger, ring finger and little finger of the middle finger will have linkage actions. The linkage of these three fingers has caused the existing theoretical attitude acquisition technology to have a very large error when it is applied in practice, and it cannot be used in practice. Therefore, there is an urgent need for a fast and effective recognition. The operator's hand posture, the error is small, and the method of collecting hand posture with strong versatility

Embodiment 1

[0034] A method for collecting hand gestures, comprising the following steps:

[0035] S1: fixed collection hand posture device, said collection hand posture device includes a first gyroscope 1, a second gyroscope 2 and a wrist pressure sensor 3, the first gyroscope 1 is fixed on the thumb, and the first gyroscope is fixed on the index finger Fixing the second gyroscope 2, fixing the wrist pressure sensor 3 at the wrist;

[0036] S2: Set parameters, set the opening and closing degree of the first gyroscope 1 as K 1 , K 1 The value of is the opening and closing degree of the thumb, and the opening and closing degree of the second gyroscope 2 is K 2 , K 2 The value is the opening and closing degree of the index finger, and the pressure value of the wrist pressure sensor 3 is P; hold all fingers tightly, and set the K at this time 1 is 0, K 2 is 0, and the P value is P 0 ;Keep the thumb and index finger tight, and the middle finger, ring finger and little finger open, and t...

Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that it also includes step S5: K 1 、K 2 and K 3 The values ​​of are transmitted to the information processing unit 4 respectively, and the information processing unit 4 will K 1 、K 2 and K 3 The value of is converted into a control signal.

[0061] Further, in the above technical solution, the information processing unit 4 will K 1 、K 2 and K 3 The value of is converted into a control signal composed of several attitude signals, where:

[0062] W=(K 1 , K 2 , K 3 ) (5)

[0063] where W is a single attitude signal, let W 1 =(0,0,0),W 2 =(1,0,0),W 3 =(1,1,0),W 4 =(1,1,1),W 5 =(0,1,1),W 6 =(0,1,0),W 7 =(0,0,1),W 8 =(1, 0, 1), 8 kinds of hand gestures can be captured.

[0064] W 1 Corresponding to fist gesture, W 2 Corresponding to the gesture of extending the thumb while holding the other fingers, W 3 Corresponding to the gesture of extending the thumb and index finger while holding the other...

Embodiment 3

[0068] A device for collecting hand gestures, used in the method for collecting hand gestures, further comprising:

[0069] The first gyroscope 1 arranged on the thumb, the second gyroscope 2 arranged on the forefinger, and the wrist pressure sensor 3 arranged on the wrist also include an information processing unit 4, and the information processing unit 4 is respectively connected with the The first gyroscope 1, the second gyroscope 2 and the wrist pressure sensor 3 are connected.

[0070] Preferably, the first gyroscope 1 is arranged on the first knuckle of the thumb, and the second gyroscope 2 is arranged on the first knuckle of the index finger.

[0071] Due to the adoption of the above technical solution, the method for collecting hand gestures provided by the present invention can accurately locate the hand gestures, has small errors, strong versatility, conforms to the actual operating conditions of the human body, and can capture eight kinds of gestures and intermediat...

Abstract

The invention provides a method for acquiring hand postures. The method comprises the following steps: S1, fixing a device for acquiring hand postures; S2, setting parameters; S3, calculating wrist pressure parameter variation rate; S4, calculating opening degree of a middle finger, a ring finger, and a little finger; S5, transmitting values of K1, K2, and K3 to an information processing unit. The device for acquiring hand postures also comprises a first gyroscope arranged on a thumb, a second gyroscope arranged on an index finger, and a wrist pressure transducer arranged on a wrist. The device also comprises the information processing unit. The information processing unit is connected with the first gyroscope, the second gyroscope, and the wrist pressure transducer. The method for acquiring hand postures can accurately position hand postures, accords with actual operation condition of a human body, and can capture eight postures and middle postures. The method and the device are accurate and sensitive in data acquisition, and are not interfered by environment sound and light.
