FIG. 1 .FIG. 1 illustrates a schematic diagram of awearable device 100 in accordance with an embodiment of the present invention. Thewearable device 100 includes anelectronic compass 110, aCPU 120, anacceleration sensor 130, and adisplay screen 140. For example, thewearable device 100 is an electronic watch, an electronic bracelet, or other electronic device which can be wore in a wrist of a user and has waterproof function. Theelectronic compass 110 and theacceleration sensor 130 are both connected to theCPU 120. Theelectronic compass 110 is a three-dimensional magnetism sensor and configured to sense the magnetic field in three directions, i.e. X, Y, Z directions of the earth. Theelectronic compass 110 is configured to determine the direction of north via the magnetic field of the earth, and the direction of north would be a standard direction. Furthermore, there is a fixing reference direction disposed on thewearable device 100. Therefore, the absolute movement angle of thewearable device 100 can be calculated via comparing the standard direction with the fixing reference direction. Thus, theelectronic compass 110 is configured to sense movement angle or movement direction of thewearable device 100, and the information sensed by theelectronic compass 110 is thefirst movement information 111. Then, thefirst movement information 111 would be transmitted to theCPU 120 by theelectronic compass 110. - The

Then, the calculation result would be displayed on thedisplay screen 140. - Please refer to
FIG. 2 .FIG. 2 illustrates the analyzing swimming steps by the CPU. First, providing thewearable device 100 wearied by a wearer, and the wearer start swimming (step S01). Afterwards, thesecond movement information 131 of theacceleration sensor 130 would be read by the CPU 120 (step S02). Next, theCPU 120 recognizes whether thewearable device 100 is in the idle state or not (step S03). In the step S3, thesecond movement information 131 of theacceleration sensor 130 is read by theCPU 120, if thesecond movement information 131 is revealed to be horizontal moving in predetermined period, theCPU 120 would recognize thewearable device 100 is in the idle state. In other word, thewearable device 100 is moved in horizontal over predetermined period, it means the wearer is floating in water without thrashing. On the contrary, thewearable device 100 is not moved in horizontal over predetermined period, it means the wearer is thrashing. - If the determining result is negative, it means the
wearable device 100 is not in the idle state, theCUP 120 would recognize the wearer is thrashing. In this moment, theCPU 120 would access thesecond movement information 131 of theacceleration sensor 130 so as to recognize swimming posture (step S04). In the step S04, if thesecond movement information 131 is revealed to be horizontal movement, theCPU 120 will recognize the swimming posture is breast stroke. On the contrary, if thesecond movement information 131 is revealed to be vertical movement, theCPU 120 will recognize the swimming posture is freestyle. After the recognizing of swimming posture, theCPU 110 would access thefirst movement information 111 of theelectronic compass 110 so as to calculate the number of the swimming stroke of the wearer (step S05). TheCPU 120 records thefirst movement information 111 at every point in time, and theCPU 120 compares and analyzes the consecutivefirst movement information 111 so as to calculate the movement track of thewearable device 100. When the movement track is displayed in a ring-like shape, theCPU 120 recognizes one number of the swimming stroke is occurred, and accumulated the number of the swimming stroke. When the human is swimming, no matter in breast stroke or freestyle, the palm (the location of the wearing the wearable device 100) would move as a cycle. Therefore, when the movement track of the wrist is displayed in a ring-like shape, thewearable device 100 recognizes one number of the swimming stroke is occurred. Furthermore, the palm almost thrashes in vertical direction when the wearer swims in the freestyle, so thewearable device 100 recognizes the swimming posture is the freestyle when thesecond movement information 131 is revealed to be vertical movement direction. On the contrary, the palm almost thrashes in the parallel direction when the wearer swims in the breast stroke, so thewearable device 100 recognizes the swimming posture is the freestyle when thesecond movement information 131 is revealed to be parallel movement direction. - Please refer to
FIG. 3 .FIG. 3 illustrates a schematic diagram of a calculation of a movement track. For example, theCPU 120 would record thefirst movement information 111 every second. “T=1” stands for the state of theelectronic compass 110 in the first second. The arrow N is the direction of the north recognized by theelectronic compass 110, i.e. standard direction. The arrow F is the reference direction fixed on thewearable device 100. As a result of the arrow N directs the north permanently, the precisely movement direction of thewearable device 100 can be recognized via comparing the arrow N and the arrow F. For example, in T=1,wearable device 100 is moving toward northeast. TheCPU 120 records a movement angle in T=1 to T=10 and concatenate the arrow F in every time point so as to calculate movement track of thewearable device 100. In theFIG. 3 , when the movement track is displayed in a ring-like shape, the CPU can recognize one number of the swimming stroke is occurred. In addition, the order of the above-mentioned step of S04, S05 and S06 in theFIG. 2 is better embodiment of the present invention, but is not limited in it. The person having ordinary skills known in the art should know the order of the step of S04, S05 and S06 is able to be modified in random. - In the step S03, when the recognizing result is positive, it means the
wearable device 100 is in the idle state, and the wearer is not thrashing. In this moment, thefirst movement information 111 of theelectronic compass 110 would be read by theCPU 120 so as to recognize whether the wearer is in a coming-back state or not (step S06). Thefirst movement information 111 of theelectronic compass 110 would be recorded by theCPU 120, and theCPU 120 calculates the average movement direction of thewearable device 100 so as to recognize a swimming direction and average movement direction of the wearer. The average movement direction would be saved in theCPU 120. In the step S06, theCPU 120 would compare the average movement direction with the previous average movement direction. If the comparing result shows the average movement direction has been reversed, theCPU 120 will recognize the wearer has came-back, and coming-back number of the wearer can be counted. When the wearer is swimming in a swimming pool and swimming to the edge of the swimming pool, the wearer usually kicks the edge of the swimming pool to push the body forward and come-back at the edge of the swimming pool. In this moment, the both arms of wearer would extend straight forward and let the body stay parallel drifting a length of period. After the rate of drifting is slowed down, the wearer will start thrashing. Therefore, thewearable device 100 would recognize in the idle state when the wearer keep parallel moving, andwearable device 100 would compare and recognize whether the average movement direction is reversed so as to recognize the number of coming-back. - Moreover, the swimming pool length can be input to the
CPU 120 by the wearer (step S07). TheCPU 120 would calculate the coming-back number of the swimming (step S08). The swimming distance would be calculated by the number of coming-back and the swimming pool length (step S09). The swimming distance is calculated by following formula: -
The swimming distance=the swimming pool length×(the number of coming-back+1). - Beside, the weight can be input to the
