The treadmill 1 can be automatically controlled based on the result of the judgment.

5, 6, and 7 are photographs showing photographs taken by an image capturing unit 14 of the treadmill 1 in accordance with a preferred embodiment of the present invention. Here, FIG. 5 shows that the user is not standing on the running belt 10, so that the photo can see a complete identification background 12. Figure 6 shows a situation in which a user's foot is standing in the B area, wherein the light passing through the B area is recognized by the user's foot, causing a property of the pixel corresponding to the B area in the photo, such as gray. The order value is changed. Figure 7 shows a situation in which a user's foot is standing in the C area, wherein the light passing through the C area is recognized by the user's foot, causing a property of the pixel corresponding to the C area in the photo, such as gray. The order value is changed. Therefore, according to the photos captured by the two image capturing units 14, the processing unit can determine which area of the user's two feet (eg, more than 50%) is located within a fixed time. In addition, in the embodiment, if a certain identification background 12 is simultaneously obscured by the left and right feet of the user, two shaded blocks are displayed on the photo, and when the analysis is performed, the shaded block near the front of the running platform is mainly And ignore the shaded block near the back of the running table. In another embodiment, if a certain identification background 12 is simultaneously obscured by the left and right feet of the user, so that two shaded blocks are displayed on the photo, the masked block near the back of the running platform is mainly used for analysis. Ignore the shaded block near the front of the running table.

Referring to Figure 4, the processing unit can control the motion machine based on the results of the analysis. For example, if the user's feet are mostly located in the A area for a fixed period of time, the processing unit can increase the rotational speed of the running belt. If the user's feet are mostly located in the B area for a fixed period of time, no adjustment is made. If the user's feet are mostly located in the C area for a fixed period of time, the processing unit can reduce the running speed of the running belt. The adjustment of the rotational speed is performed by a driving device (not shown). According to the present creative embodiment, the A, B, and C regions may be defined as an acceleration region, a constant region, and a deceleration region, respectively. In another embodiment of the present creation, the number of regions is not limited to three.

Referring to FIG. 4, according to the present embodiment, the range of the three areas A, B, and C may be determined in advance, but may also be input by the user. For example, if the length of the running belt 10 for the user to operate is 120 cm, the lengths of the three regions A, B, and C may be predetermined to be 30 cm, 50 cm, and 40 cm, respectively. Alternatively, the user can change the setting and change the length of each area. For example, the three areas A, B, and C are changed to 35 cm, 50 cm, and 35 cm, respectively.

The moving machine table 1 of the present embodiment, such as the treadmill 1, further includes a lifting device (not shown) that adjusts the gradient of the running belt 10. . In addition, the portion of the running belt 10 for the user to operate includes a slope increasing area and a slope reducing area, such as the R and L areas in the illustration. In an embodiment, if the user exceeds a certain proportion (for example, 50%) of the feet in the slope increasing area R within a fixed time, the slope of the running belt is increased; if the user exceeds one foot in a fixed time The ratio (for example, 50%) is located in the slope reduction area L, which reduces the slope of the running belt. Since the user moves to the right or to the left, the angle of the shaded light is changed, so that the user's feet are located in which area. FIG. 9 shows an example of the operation of the treadmill 1 of FIG. For example, if the user moves to the area R, the image captured by the right image capturing unit 14 identifies the area where the background 12 is obscured by the user, and the recognition background 12 of the image captured by the left image capturing unit 14 is The area shaded by the user comes later. Similarly, if the user moves to the area L, the image captured by the right image capturing unit 14 recognizes that the background 12 is obscured by the user, and the recognition background of the image captured by the left image capturing unit 14 is 12 The area that is obscured by the user comes more forward. Therefore, if the masked area of the image captured by the left and right image capturing unit 14 continues for a period of time, for example, within 5 seconds, the difference between the front and rear positions reaches a ratio of the length of the recognition background 12, for example, 10% or more, or 5%. When it is 40%, it is judged that the user moves to the area R or the area L. In another embodiment of the present creation, the positions of the slope increasing region R and the slope reducing region L may be interchanged.
