Method for measuring movement of cervical vertebra, device thereof and wearable apparatus
First Claim
1. A device for measuring a movement of a cervical vertebra, comprising:
- a sensor configured to sense a corresponding plurality of movement angles of the cervical vertebra for a plurality of movements of the cervical vertebra during a predetermined measurement period, wherein each of the plurality of movements of the cervical vertebra comprises a first motion process and a second motion process which have inverse directions and whose starting instantaneous velocities and stopping instantaneous velocities are both zero;
a microcontroller unit comprising;
an obtaining unit configured to obtain the plurality of movement angles of the cervical vertebra sensed by the sensor, wherein each of the plurality of movement angles of the cervical vertebra is an angle whose absolute value is greater between a first angle which is a maximum angle made by the cervical vertebra during the first motion process and a second angle which is a maximum angle made by the cervical vertebra during the second motion process during a corresponding one of the plurality of movements of the cervical vertebra, anda processing unit configured to calculate a movement total amount of the cervical vertebra during the predetermined measurement period based on the plurality of movement angles of the cervical vertebra,wherein, the processing unit acquires a plurality of movement arc lengths, each being corresponding to one of the plurality of movements of the cervical vertebra and determined based on a corresponding one of the plurality of movement angles of the cervical vertebra corresponding to the one of the plurality of movements of the cervical vertebra, and accumulates a sum of the plurality of movement arc lengths for the plurality of movements of the cervical vertebra acquired during the predetermined measurement period as the movement total amount of the cervical vertebra; and
a notifying unit configured to provide an alarm to a user by sounds or vibrations for prompting that the user needs to move the cervical vertebra when the movement total amount of the cervical vertebra during the predetermined measurement period is less than a predetermined threshold value of the movement amount,wherein, if a movement angle among the plurality of movement angles of the cervical vertebra is greater than or equal to a valid movement threshold value, the processing unit records the corresponding one of the plurality of movements of the cervical vertebra as a valid movement of the cervical vertebra, and counts the valid movements of the cervical vertebra during the measurement period as a valid movement number of the cervical vertebra.

Abstract
Embodiments of the present disclosure provide a method for measuring a movement of the cervical vertebra, a device thereof and a wearable apparatus. The method for measuring a movement of the cervical vertebra comprises: obtaining a movement angle of the cervical vertebra with a sensor; and calculating a movement amount of the cervical vertebra based on the movement angle of the cervical vertebra. Therefore, according to embodiments of the present disclosure, exact data values of the movement angles of the cervical vertebra can be acquired with the sensor, and the movement amount of the cervical vertebra can be calculated on the basis of this, thereby a quantitative value of the movement of the cervical vertebra can be acquired exactly in form of a numerical value, which is convenient for future processings.
