Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Examples

An embodiment of the present invention provides a helmrick first-aid teaching system, as shown in fig. 1, including:

an AR device 101 worn on the head of a user for providing a 3D virtual person as a symptomatic representation of a patient in need of a helmrick emergency;

the dummy 102 is used as a real object of the 3D virtual person to provide real object operation for a user, and is overlapped with the 3D virtual person;

the camera 103 is arranged right in front of the dummy 102 and is used for collecting the hand position and hand action of a user for performing the Haimlik emergency operation on the dummy;

the AR device 101 is further configured to determine whether the hand position and the hand motion are correct based on the hand position and the hand motion acquired by the camera 103 and used for performing the helminth emergency operation on the analog person 102 by the user, and feed back the hand position and the hand motion to the user.

Specifically, as shown in fig. 2, a dummy 102 is provided, where the dummy 102 simulates a normal human body proportion, and the dummy 102 is a real object of a 3D virtual person, so as to provide a real object operation for a user, and is coincident with the 3D virtual person, so as to achieve a real effect.

The AR device 101 may provide a virtual image for the user on the one hand, and on the other hand, the AR device 101 in combination with the camera 103 provides an interactive operation for the user.

In a specific embodiment, the user wears the AR device 101, which may be an AR helmet or an AR glasses, or may be other wearable devices, which is not limited herein.

The AR device 101 is used to provide a holographic image guiding the operation of the helmholtz emergency before the 3D virtual person is presented as a symptom of the patient in need of the helmholtz emergency. By this image, the user can grasp the operation key of the Haimrick emergency operation.

Next, the AR device 101 is used to provide a 3D virtual person as a symptomatic representation of a patient in need of a helmholck emergency.

Moreover, the AR device 101 is further configured to provide a dialogue situation of the 3D virtual person based on the user's inquiry when the user inquires about the symptoms of the dummy 102.

The 3D virtual person coincides with the dummy 102, and the user observes the symptoms of the 3D virtual person on the front of the dummy 102, and if a patient needs a helmrick emergency, the symptoms of the 3D virtual person are displayed by the VR device 101, and the symptoms are particularly flushed complexion, lips, nail bed bluish violet, unable to breathe, and the symptoms of the neck being grasped by both hands. When the user observes such a symptom expression, the 3D dummy is asked for the condition, and after the VR device 101 captures the inquiring operation of the user, a corresponding reply expression is provided by the 3D dummy based on the inquiring operation. To determine that the 3D virtual person is choked with a foreign object.

Next, the user goes to simulate the back of the person 102, performing an emergency operation. Specifically, the user holds a fist with one hand, places one thumb on the abdomen below the chest and above the navel of the dummy 102, and holds the fist with the other hand, and rapidly impacts and presses the abdomen of the dummy 102 upwards, so that the foreign matters are discharged.

In the course of the user performing the above-described operations, the AR device also provides a respiratory system model of the 3D virtual person, in which foreign objects are simulated.

Moreover, the AR device 101 also provides a change in the position of the foreign object as the user performs a helmholck emergency operation. I.e. the position of the obstruction of the foreign body, the variation of the position of the obstruction and the discharge of the foreign body from the mouth, during the execution of the helmholck emergency operation by the user.

Specifically, as shown in fig. 3, the respiratory system model provided by the AR device includes: nasal cavity, throat, airways, trachea, left bronchi, right bronchi, left lobes and right lobes. Thus truly simulating the respiratory system of a person.

Of course, most importantly, with this system, a real emergency experience can be provided, and the AR device 101 is configured to determine whether the hand position and hand motion are normal based on the hand position and hand motion acquired by the camera 103 of the user performing the helminth emergency operation on the dummy 102.

That is, whether one hand of the user holds a fist and is located on the abdomen below the chest and above the navel of the dummy 102 is determined by the camera, whether the other hand holds the fist and whether there is a rapid upward impact pressing operation of the abdomen of the dummy 102, as shown in fig. 4, which is the abdomen position 401. If the above position and the motion are correct, the foreign matter can be discharged quickly.

Of course, the above-described operation is only one hand operation, and other hand operations may be used for the helmholck emergency operation, and the present invention is not limited to this, as shown in fig. 5, and the gesture operation is set up internally. Regardless of the gesture, the camera 103 can accurately acquire and transmit the gesture to the AR device for judgment. The specific determination process relates to image recognition and is not limited herein.

In a specific embodiment, the distance between the camera 103 and the dummy 102 is kept at a preset distance, and the camera 103 has a preset viewing angle, so that the camera 103 can accurately capture the operation of the user. Specifically, as shown in fig. 6, the distance between the camera 103 and the dummy 102 is 1800mm. The camera 103 has a horizontal angle of view of 67.5 ° and a vertical angle of view of 53.2 °.

The preset distance and the preset viewing angle are both determined based on the size of the dummy 102.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the invention.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
