[0127] In this embodiment, the three-dimensional coordinates of the monitoring point of the smart ring are calibrated and obtained in the three-dimensional posture description information when the smart ring is worn by the patient through the preset setting position of the monitoring point of the smart ring in the smart ring.

[0128] The beneficial effect of the above technology is: by introducing the limit pressure values ​​corresponding to multiple pressure sensors evenly arranged on the inside of the smart ring under the current three-dimensional posture description information and the monitoring influence distance of each pressure sensor evenly arranged on the inside of the smart ring, the first skin fit of the smart ring when worn by the patient can be accurately determined.
