The third area represents the sequence number of the message. Acceleration information (measured acceleration change amount) during motion is stored in the 3 to 8 byte area. In the 9 to 14 byte area, the angular velocity information during exercise For example, swing angle information in the case of a golf club).

The operation of the smart activity monitor system configured as described above will now be described in detail with reference to FIG.

The activity monitor 100 basically supports two modes (activity meter mode, motion trajectory mode) and can switch modes according to a user's direct input or remote management command.

First, when the physical activity amount sensing is requested according to the user operation, the user switches the mode to the physical activity amount sensing mode, and informs the user through the indicator LED unit that the mode is the physical activity amount sensing mode (steps 500 and 502). Such a physical activity sensing mode can be used in a state where the activity monitor 100 is attached to the user's body during jogging or climbing, as shown in FIG.

Thereafter, the activity monitor 100 senses the three-axis acceleration and the angular velocity, calculates the amount of physical activity using the sensed value, transmits the amount of physical activity information to the interaction unit 102 every predetermined period, (Step 504). For example, the amount of physical activity may be the number of steps, consumed calories, travel distance, etc., and the measured time may be 10 seconds or longer, and information measured at intervals of 10 seconds may be transmitted. At this time, the interaction unit 102 receives the physical activity amount information, displays the physical activity amount information on the LCD, and stores the information in the internal flash memory (step 506). It is also checked whether the USB dongle 104 and the host 105 are connected to each other in step 516. If the USB monitor 104 is connected to the host device through the USB dongle 104, The USB dongle unit 104 transmits the activity amount information to the host device 105 in step 520. The USB dongle unit 104 transmits the activity amount information to the USB dongle unit 104 in step 518. If the connection is not established in step 516, the host device 105 checks whether the connection is established through the USB dongle part 104 for a predetermined period. When the connection is established with the host device, The physical activity amount information stored in the internal flash memory of the USB dongle unit 104 (step 519). Therefore, it is possible to receive the physical activity amount information from the activity monitor 100 in a real time and receive the physical activity amount information stored in the interaction unit 102, thereby preventing loss of the transmitted physical activity amount information .

Unlike the above, the activity monitor 100 switches to the object motion sensing mode when the object motion sensing is requested according to a user operation, and guides the object motion sensing mode through the indicator LED unit (steps 508 and 510). Such an object motion sensing mode can be used in a state in which an activity monitor 102 is attached to a fitness apparatus during sports activities using golf, baseball, tennis, or the like, as shown in FIG.

Then, the activity monitor 100 senses the three-axis acceleration and the angular velocity, and uses the sensed value to construct object motion information, which is a predetermined number of sensing data sets from before the motion of the object to the end of the motion, Information is transmitted to the interaction unit 102 or the USB dongle unit 104 (step 512). At this time, the interaction unit 102 receives the object motion information, displays it on the LCD, and stores the motion information in an internal flash memory (step 514). It is also checked whether the USB dongle 104 and the host 105 are connected to each other in step 516. If the USB dongle 104 is connected to the host device through the USB dongle 104, The USB dongle 104 transmits the motion information to the host device (step 520). If the connection is not established in step 516, the host device 105 checks whether the connection is established through the USB dongle part 104 for a predetermined period. When the connection is established with the host device, The object motion information stored in the internal flash memory of the USB dongle 104 is transferred to the USB dongle 104 (step 519). Accordingly, the object motion information is received from the activity monitor 100 in real time, and the object motion information stored in the interaction unit 102 is transmitted to the motion monitor 100 to prevent loss of the transmitted object motion information .

Then, the host device 105 such as a portable terminal or a PC displays the physical activity amount information and the object motion information received from the USB dongle 104 and informs the user of the physical activity amount information and the object motion information in step 522.

FIG. 9 is a photograph showing an example in which an activity monitor according to a preferred embodiment of the present invention is attached to a golf club, and FIG. 10 is a photograph showing an example in which a USB dongle according to a preferred embodiment of the present invention is connected to a notebook computer. 9 and 10, the data sensed through the sensor module of the activity monitor 100 of the golf flop is transmitted to the USB dongle 104 in a batch.

At this time, a 300 message including measurement data in one swing for three seconds including two seconds before the specific motion is transmitted in a stream mode. An example of motion data (angular velocity and acceleration) obtained through the activity monitor is shown in FIG. 11 In the graph. Referring to FIG. 11, the measured data has a length of 16 bytes and represents a communication packet of sequence number 0 received from the activity monitor in the first row of the table, and the 2-byte area following the sequence number represents the acceleration value Acc_x ) Is similar to Acc_x = 131 (0x83) * 256 + 64 (0x40) = 33600 and the acceleration value Acc_y of the Y axis and the acceleration value Acc_z of the Z axis can be similarly obtained.

FIG. 12 is a graph showing a swing angle according to a preferred embodiment of the present invention, and FIG. 13 is a graph showing a swing acceleration according to a preferred embodiment of the present invention.

Referring to FIG. 12, it can be seen from the motion analysis module that the trajectory of the golf club changes steeply in all directions at the swing angle.

The y-axis of acceleration represents the vertical motion of the golf club. Referring to FIG. 13, the curve of the y-axis changes steeply, and it can be seen that the up-down movement of the y-axis moved at a very large rate during swing.

As described above, the golf swing motion is shown based on the three-axis angular velocity and acceleration information of the present invention. This is because the trajectory of the golf club can be calculated based on the direction and the rotation angle of the three axes, .

In addition, the power can be estimated based on the measured acceleration, and the impact point can be detected by continually measuring the increase or decrease of the acceleration. This allows the user to analyze and correct the swing postures themselves.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
