Therefore, the third detection information reflects the distance change between the first proximity sensor 82 and the user's left foot, and the fourth detection information reflects the distance between the second proximity sensor 83 and the user's left foot. The distance between the right foot changes; in other words, the third detection information is actually an analog signal whose amplitude changes as the distance between the first proximity sensor 82 and the user's left foot changes , and the fourth detection information is actually an analog signal whose amplitude varies with the distance between the second proximity sensor 83 and the user's right foot. And the closer the distance between the first proximity sensor 82 and the left foot of the user P, the higher the amplitude of the third detection information, and vice versa, the lower the amplitude; similarly, the second proximity sensor The closer the distance between 83 and the right foot of the user P, the higher the amplitude of the fourth detection information, and vice versa.

In this embodiment, as shown in FIG. 2 and FIG. 3 , the wireless transmission module 81 is fixed on the lower end of the support column 31 , and the first proximity sensor 82 and the second proximity sensor 83 are fixed The two convex portions 241 and 242 on opposite sides of the annular guide rail 24 face the tread surface 20 of the tread platform 2 and face each other. Specifically, as shown in FIG. 1 and FIG. 2 , the support unit 3 also has two support rods 33 , and one end of the support rods 33 is connected with the two convex parts 241 and 242 on the opposite side of the annular guide rail 24 to form On the opposite side of the annular guide rail 24 , the other ends of the support rods 33 are connected to the support column 31 , and the first proximity sensor 82 and the second proximity sensor of the third wireless sensing device 8 83 is not fixed on one end of the support rods 31 connected with the annular guide rail 24 and is located on the opposite side of the annular guide rail 24 and faces the treading surface 20 of the treading platform 2 .

The information processing device 1 includes an arithmetic module, and uses the arithmetic module to analyze and calculate the received first detection information, the second detection information, the third detection information and the fourth detection information , to judge whether the user's action is forward, backward, move laterally in the direction of the first proximity sensor 82 or move laterally in the direction of the second proximity sensor 83, and generate a corresponding one according to the judgment result. An operation signal, the operation signal includes an instruction to move forward, backward, move to the left or move to the right. The process of generating the operation signal by the arithmetic module will be described in detail below.

User goes forward or backward ( straight line ) move ( walk ) way of judging

When the user's feet are stepping up and down on the stepping platform 2 , the waveforms W1 and W2 of the first detection information received by the computing module are shown in FIG. 15 , wherein the waveform W1 indicates that the wearer is wearing The distance between the infrared proximity sensor of the user's left foot and the tread surface 20 of the treading platform 2 changes. The lower the amplitude value of the waveform W1, the farther the bottom of the user's left foot is from the tread surface 20, and vice versa. Waveform W2 represents the distance change between the infrared proximity sensor worn on the user's right foot and the tread surface 20 of the stepping platform 2, the lower the amplitude value of the waveform W2, the lower the bottom of the user's right foot from the tread surface. 20 is farther away, vice versa; therefore, the calculation module determines that the amplitude of each first detection information is lower than a height threshold (for example, the height threshold of waveform W1 is 140, and the height threshold of waveform W2 is 80). And determine that the waveforms W1 and W2 of the first detection information have positive or negative slope changes; at the same time, as shown in FIG. 15 , the calculation module determines that the amplitude of the waveform W3 of the second detection information is smaller than a front and rear valve A value (for example, 250), the calculation module determines that the user's action is to move forward, and then generates the operation signal including the command indicating moving forward.

Conversely, as shown in FIG. 16 , when the calculation module determines that the amplitude of each first detection information is lower than the height threshold (the height threshold of waveform W1 is 140, and the height threshold of waveform W2 is 80) and determines Each waveform of the first detection information has a positive or negative slope change, but the calculation module determines that the amplitude of the waveform W3 of the second detection information is greater than the front and rear threshold (250) and determines the second detection information The waveform W3 of is a positive slope, and the calculation module determines that the user's action is to retreat, and then generates the operation signal including the command indicating the retreat.

Moreover, after the calculation module generates the operation signal including the command indicating the retreat, as shown in FIG. 17 , when the calculation module determines that the waveform W3 of the second detection information has a negative slope, the calculation module will continue to Generate the operation signal including the command to instruct to retreat until as shown in FIG. 18 , the arithmetic module determines that the amplitude of the second detection information is smaller than the front and rear threshold (250) and each of the first detection information (W1 or The amplitude of W2) rises from below the height threshold to above the height threshold; thereby, it can be avoided that when the user's left foot or right foot has not stepped back on the tread surface 20, the second detection information The amplitude is less than the forward and backward threshold (250), so that the operation module suddenly changes from generating the operation signal including the command indicating backward to generating the operation signal including the command indicating forward, and avoids bringing Bad gaming experience for users.

In addition, the calculation module also calculates a vertical stepping intensity of the forward or backward movement of the user according to the first detection information. As shown in FIG. 15 , the calculation module sets a threshold, and the threshold is the first step. A certain value on a complete cycle of detection information, for example, as shown in FIG. 15 , the value 140 is used as the height threshold of the waveform W1 of the first detection information, which can represent the threshold of foot lift; then , the calculation module finds a point A and a point B with the threshold value in the complete cycle and a reversal point C of the complete cycle, and according to the time when points A and B occur and the horizontal distance between points A and B d1 calculates a vertical pedaling speed V1 of the foot, such as the left foot, and obtains a pedaling height S according to the distance between point A (or point B) and the turning point C, and obtains the vertical pedaling intensity equal to S divided by V1 multiplied by Take K, where K is a coefficient for adjustment; thereby, the calculation module will generate the operation signal including the command instructing forward or backward according to the above judgment result and the vertical pedaling strength, and simulate it as a game joystick, such as When judging to move forward, the vertical stepping intensity is converted into a value of 0-125 and used as the forward command to indicate the forward speed, which is equivalent to the user moving the joystick forward and the force of the toggling. Of course, the calculation of the vertical stepping strength is not necessary and can be omitted depending on the usage situation. Therefore, the operation signal will only simulate (equivalent to) the action of the user moving the joystick forward or backward.

User moves sideways ( walk ) way of judging

When one of the user's feet relative to the other foot on the pedal platform 2 to simulate the opening and closing action of CROSSOVER STEP, for example, when the user wants to simulate moving to the left, the user's left foot should repeatedly Make the action of approaching the right foot and moving away from the right foot. Similarly, when moving to the right, the user's right foot should repeatedly make the action of approaching the left foot and moving away from the left foot. Therefore, as shown in FIG. 19, when the calculation module determines that the amplitude of the first detection information (waveform W1) is lower than the height threshold (80) and the amplitude of the third detection information (waveform W4) is greater than a When the lateral movement threshold (for example, 30), the calculation module determines that the user's action is to move laterally in the direction of the first proximity sensor 82, and then the calculation module generates a command that includes the instruction to move to the left. the operation signal; it can be seen from this that the same is true, when the calculation module determines that the amplitude of the first detection information (waveform W2) is lower than the height threshold (140) and the amplitude of the fourth detection information (waveform W5) When it is greater than the lateral movement threshold (30), the calculation module determines that the user's action is to move laterally in the direction of the second proximity sensor 83, and the calculation module generates the command that includes an instruction to move to the right of the operation signal.

Moreover, after the calculation module generates the operation signal including the command instructing to move to the left, as shown in FIG. 20 , when the calculation module determines that the amplitude of the third detection information (waveform W4 ) gradually decreases, the calculation The module will continue to generate the operation signal including the command to move to the left until the range shown in the dotted box in Figure 21, the calculation module determines that the amplitude of the third detection information (waveform W4) is smaller than the side shift valve value (30) and the amplitude of the first detection information (waveform W1) rises from below the height threshold (80) to above the height threshold (80); it can be seen that the same is true when the calculation module generates After the operation signal including the instruction instructing to move to the right, the arithmetic module will continue to generate the instruction including the instruction to move to the right when the arithmetic module determines that the amplitude of the fourth detection information (waveform W5) gradually decreases The operation signal is maintained until the arithmetic module determines that the amplitude of the fourth detection information (waveform W5 ) is less than the lateral shift threshold and the amplitude of the first detection information (waveform W2 ) is never lower than the height threshold (140 ) rises above the height threshold (140). In this way, it can be avoided that when the user's left foot (or right foot) has moved away from the proximity sensor 82 (or 83 ) on its side, but the left foot (or right foot) has not yet retrieved the tread surface 20 , if the amplitude of the second detection information ( W3 ) is smaller than the front and rear threshold ( 250 ), the operation module suddenly generates the operation signal including the command to instruct to move forward, so as to avoid adverse effects on the user game experience.

In addition, the calculation module also uses the amplitudes of the third detection information and the fourth detection information as the lateral movement intensity of the user, whereby the calculation module uses the above judgment result and the lateral movement intensity The movement intensity generates the operation signal including the instruction to move to the left or to the right, and simulates it as a game joystick. The value is used as the leftward movement command to indicate the leftward movement speed, which is equivalent to the user turning the joystick to the left and the force of the turning. Of course, the calculation of the lateral movement intensity is not necessary and can be omitted depending on the usage situation. Therefore, the operation signal will only simulate (equivalent to) the action of the user turning the joystick left or right.
