In FIG. 1, the evoked body imbalance system 10 is capable of inducing that the subject 2 exhibits a near-real body imbalance posture between the virtual space 12 and the real space 14. Physical imbalance gesture refers to the subject Under the original body balance posture, the body of 2 is unable to maintain a stable standing, kneeling posture, kneeling posture, etc. due to reasons such as falling, slipping, falling, knocking down, and the like.

The virtual space 12 refers to a multi-dimensional space created by, for example, a computer program, the subject 2 seeing the multi-dimensional space through, for example, an eye; and the real space 14 refers to the presence of the subject 2 Real space.

The evoked body imbalance system 10 includes an obstacle unit 16, a virtual reality display unit 18, a detection unit 20, and a processing unit 22.

The obstacle unit 16 is disposed in the real space 14. The obstacle unit 16 may be disposed at an unspecified position of the real space 14, and the specific position may be unpredictable by the subject 2 or the obstacle unit 16 may be fixedly disposed at a certain position of the real space 14.

The obstacle unit 16 is capable of changing the body posture of the subject 2, causing the subject 2 to transition from a body balance posture to a body imbalance posture. For example, reference can be made to FIG. 2 and FIG. 3 together. In FIG. 2, the subject 2 exhibits a walking posture; and, in FIG. 3, the subject 2 in FIG. 2 is shown to have encountered the obstacle unit 16 due to no expectation, resulting in the subject 2 taking a walking posture (ie, The body balance posture) is transformed into a slip posture (ie, an unbalanced posture of the body).

Returning to FIG. 1, the virtual reality display unit 18 forms the virtual space 12. The virtual reality display unit 18 may be one of a virtual reality (VR), a mixed reality (MR), and an augmented reality (AR). In this embodiment, the virtual reality display unit 18 is illustrated by taking the virtual reality as an example, that is, a computer program simulates a three-dimensional space, and the subject 2 is wearing the virtual reality display unit 18 (for example, After the virtual reality glasses, the virtual space 12 is seen. The material of the virtual space 12 is embedded with a plurality of images, and the images may be converted according to the viewing angle and/or the moving behavior of the subject 2 (eg, moving direction, moving speed, etc.), etc., that is, the virtual The reality display unit 18 may select the images along with the viewing angle of the subject 2 and/or the movement behavior or the like. In the virtual space 12, in order for the subject 2 to encounter the obstacle unit 16 without warning, the subject 2 will not be able to directly know the position of the obstacle unit 16 or the point in time at which it appears. In the present embodiment, the above object can be achieved by masking the obstacle unit 16 by the images.

Briefly, the virtual reality display unit 18 visually interferes with the subject 2 to allow the subject 2 to encounter the obstacle unit 16 at an unspecified location or time point, thereby enabling the subject 2 to Unexpectedly showing the closest to the body of this unbalanced posture.

For the purpose of research, training, or other purposes, when the body imbalance posture occurs, the detecting unit 20 and the processing unit 22 can confirm whether the subject 2 is induced to exhibit a near-real body imbalance posture. The detecting unit 20 and the processing unit 22 are described.

The detecting unit 20 also outputs the detected data DD to the virtual reality display unit 18. The detecting unit 20 can detect the change of the body posture and the movement behavior of the subject 2 by means of detection methods such as image, sound, light, pressure, acceleration gauge, gyroscope, and electronic compass. Furthermore, the virtual reality display unit 18 can display suitable images in the virtual space 12 according to the detection data DD. For example, when the subject 2 looks up, the blue sky and white clouds can be seen, and when the head is down, the road can be seen. As well as moving forward, the scene also moves forward.

For example, the detecting unit 20 can be a complex motion capture camera or a wearable sensor IMU (not shown). The cameras may be provided at the corners of the real space 14 for capturing the image of the body posture and the movement behavior of the subject 2 at various angles. The body balance posture of the subject 2, the body imbalance posture or the subject 2 has contacted the obstacle unit 16 by the images.

The processing unit 22 is connected to the virtual reality display unit 18 and the detecting unit 20. The processing unit 22 executes a calculation program (not shown) to calculate the images to confirm that the body posture belongs to the body balance posture or the body imbalance posture, and can also be used to determine whether the obstacle unit 16 has been touched.

In another embodiment, if the processing unit 22 confirms that the body posture belongs to the body imbalance posture or confirms that the obstacle unit 16 has been touched, the processing unit 22 may add the images of the virtual reality display unit 18 to the images. A special image object (not shown), such as an image or a text. The special imaging object provides a visual image of the subject 2 in the event of the unbalanced posture of the body.

The sensor 162 can be a weight sensor, a speed sensor, an acceleration sensor, a direction sensor, a displacement sensor and a pressure sensor, and the like.

For example, the obstacle unit 16' sets the displacement sensor, and if the subject 2 has no warning to contact the obstacle unit 16', the displacement sensor can detect the obstacle unit 16' toward a certain Move in direction. Due to the positional change of the obstacle unit 16', the displacement sensor generates the sensing material SD containing the position information. The processing unit 22 can analyze the detection data DD and the sensing data SD to confirm that the body posture of the subject 2 belongs to a body balance posture, a body imbalance posture, or the subject 2 has contacted the obstacle unit. 16'.

Compared with the first embodiment, in addition to determining the body posture of the subject 2 by using the detection data DD, the sensing data SD can be used to assist the activation of the processing unit 22, or by using the detection data SD. The sensory data SD assists in confirming the body posture of the subject 2.

It should be noted that the processing unit 22 can also synchronously record the body imbalance posture and its corresponding sensing material SD. By recording the sensing data SD, it is possible to analyze the related data when the subject 2 has a body imbalance posture and a body balance posture. These data can be used as a related application to alert the body to an unbalanced posture.
