Embodiment Construction

[0104] The implementation flow chart of the present invention is as figure 1 As shown, the specific implementation steps are as follows:

[0105] Step 1: The user completes the specified body movement through the Wii Fit balance board. Since the four corners of the balance board are equipped with sensors, various pressures will be generated after the person completes the designated movement on it, and the pressure sensors at the four corners will feel The effect of the pressure produces four voltage signals. After calculating these four voltage signals, the projected position of the center of gravity of the user's pressure on the balance plate can be obtained, and then the position coordinates of the four corners A(x 1 ,y 1 ), B(x 2 ,y 2 ), C(x 3 ,y 3 ),D(x 4 ,y 4 ), and its difference data D ab (Δx 12 ,Δy 12 ), D ac (Δx 13 , Δy 13 ), D cd (Δx 34 ,Δy 34 ), D ad (Δx 14 ,Δy 14 ) and their mean square error data Var(Δx, Δy) form the training data data, which is...

Abstract

The invention discloses a dynamic monitoring method of the health conditions of a user based on a balance plate. An existing method cannot timely and effectively solve the monitoring problem of the health conditions of the user and the processing procedures are complicated. The dynamic monitoring method of the health conditions of the user based on the balance plate comprises the following steps that the training data of a wii balance plate user is acquired; the data is preprocessed; then the semantic features of the processed data are extracted; the training of the accumulation of normal state knowledge, i.e. HMM is carried out with the semantic features as observed quantity; and finally, the changes of the health conditions are judged according to an acquired model and the semantic features. According to the dynamic monitoring method of the health conditions of the user based on the balance plate, the purposes of quickly and precisely monitoring and accumulating normal state knowledge while monitoring and training are achieved, the monitoring problems when the health conditions of the user are unknown are well solved, so that the monitoring is more intelligent.

Description

technical field [0001] The invention belongs to the technical field of data anomaly detection, and in particular relates to a dynamic monitoring method based on a balance board user's health status Background technique [0002] Scholars at home and abroad have been exploring various detection methods of human balance dysfunction, and developed a variety of detection methods for human balance dysfunction. The traditional test method of balance function is the observation method: the earliest clinically established Romberg test method, also known as the eye-closed standing test method, uses the naked eye to observe the subject's body shaking when the eyes are opened and closed when the two feet are close together and upright. Condition. In 1966, Graybie improved the simple upright test with the feet close together in the Romberg test. He began to use the single-leg upright test method and the enhanced Romberg test method in clinical practice. The specific method is that the f...
