Problems solved by technology

[0004] The present invention solves the problem that the existing hula hoop is inconvenient to use, and provides a method for realizing a virtual electronic hula hoop based on an accelerometer. The method judges whether a hula hoop movement is completed by analyzing the waveform characteristics of the accelerometer in the hula hoop movement. Thereby completely solving the inconvenient use problem of the traditional hula hoop

Embodiment Construction

[0061] In conjunction with the description of the accompanying drawings, the present invention is described below.

[0062] figure 1 It is a schematic diagram of a virtual electronic hula hoop, and the principle of the present invention is divided into the following 3 steps as a whole, as follows:

[0063] Step 1: Feature extraction of training samples

[0064] First recruit 10 volunteers to do the traditional hula hoop exercise, wear the hardware on the waist of the volunteers, each volunteer turns 500 times, and collects the acceleration data during the exercise as a training sample. The frequency of accelerometer reading data is 100Hz. Then use the Kalman filter to filter out some abnormal data in the training samples, and obtain the available training set through filtering. The data in the training set is divided into three categories, which are the data of the accelerometer X, Y, and Z axes. The data of each axis is continuous in time, with time as the abscissa and v...

Abstract

The invention discloses an implementation method of a virtual hula hoop based on an accelerometer. The implementation method comprises the following steps: acquiring acceleration data of movement of the hula hoop as training samples, carrying out filtering treatment on the training samples by adopting a kalman filter, and carrying out classification algorithm treatment by adopting a naive bayes classifier. When people doing exercise make waist twisting movements by wearing the virtual hula hoop on the waist, through the classification algorithm, whether the waist twisting strength and amplitude of the people achieve the movement level of the real hula hoop or not is judged, if so, the one circle of movement of the virtual hula hoop is recorded, and finally, the movement result is sent to a mobile phone terminal through Bluetooth equipment so that a user can conveniently check the result.

Description

technical field [0001] The invention mainly relates to a software and hardware realization method of electronic sports equipment, belonging to the field of electronic sports equipment. Background technique [0002] Hula hoop exercise is very popular at present, and it is very beneficial to health, but traditional hula hoop is very bulky and inconvenient to carry, can not carry out exercise in narrow space. Many people need to do this exercise every day, but the limitations of the hula hoop prevent them from doing it every day. Simultaneously the bulkiness of traditional hula hoop also can cause the injury to a certain degree to the waist of sportsman. [0003] In response to the above problems, we have designed a virtual electronic hula hoop based on an accelerometer by using embedded technology. The circuit board size of this electronic device is very small and easy to carry. sports. If the strength of the athlete's waist twisting reaches the level of turning a tradition...
