Furthermore, manual power on and off is required, making it difficult to operate when used frequently or by a large number of people. While some models feature displays with multiple functions, such as music playback and video viewing, manual operation is still required to accelerate, slow down, or stop running, lacking interactivity.

Modes for Carrying Out the Invention

[0043] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] As shown in Figures 1 to 10, the present invention provides an interactive device based on a pressure acquisition system, including: a stress-bearing layer 1, an array pressure sensor 2, a supporting layer 3, a base 4, a control module and an execution module 5, and the supporting layer 3 is fixedly set on the base 4, the array pressure sensor 2 is fixedly set on the supporting layer 3, and the stress-bearing layer 1 is covered on the array pressure sensor 2, wherein the stress-bearing layer 1 is used to obtain external pressure signals and act on the array sensor, and the array sensor is used to send the received pressure signals to the control module. There are multiple control modes preset in the control module. The control module obtains corresponding position information according to the arrangement sequence number of the sensor point corresponding to the received pressure signal in the array sensor. Finally, the control module controls the execution module 5 to execute the corresponding movement under the currently selected control mode according to the real-time received pressure signal and the change of position information.

[0046] The present invention provides an interactive device based on a pressure acquisition system, which controls the execution module 5 to execute a corresponding control mode through changes in pressure signals and position information without the need for manual operation by the user, thereby improving the linkage and intelligence between the user and the interactive device.

[0047] It is further pointed out that the control module obtains the area and edge position information of the associated area where the same force-applying object is located based on the received pressure signal and position information, and then obtains the center of gravity coordinates of the associated area based on the area and edge position information of the associated area. The control module generates a control instruction corresponding to the currently selected control mode based on the real-time change of the center of gravity coordinates, and sends it to the execution module 5. The execution module 5 performs the corresponding action according to the received control instruction.

[0048] Preferably, the control mode includes a running mode and an entertainment mode.

[0049] It is worth mentioning that when the control mode is the running mode, the control module obtains the user's continuous progress on the interactive device, and the user's left foot generates the corresponding first left foot area center of gravity coordinate, second left foot area center of gravity coordinate and third left foot area center of gravity coordinate from front to back in time, and the user's right foot generates the corresponding first right foot area center of gravity coordinate, second right foot area center of gravity coordinate and third right foot area center of gravity coordinate from front to back in time. If the first left foot area center of gravity coordinate, the first right foot area center of gravity coordinate, the second left foot area center of gravity coordinate, the second right foot area center of gravity coordinate, the third left foot area center of gravity coordinate and the third right foot area center of gravity coordinate appear alternately and the coordinate values ​​gradually move towards the front of the interactive device, the control module sends an instruction to the execution module 5 to prompt the execution module 5 to rotate forward.

[0050] Among them, the control module obtains the corresponding position information according to the arrangement number of the sensor point corresponding to the received pressure signal in the entire array pressure sensor 2. For example, if the number of columns of the array pressure sensor 2 is 16, the serial numbers are sorted from left to right and from top to bottom. If the arrangement number of the first sensor point in the entire array pressure sensor 2 is 8, the arrangement number of the second sensor point in the entire array pressure sensor 2 is 20, and the arrangement number of the third sensor point in the entire array pressure sensor 2 is 36, then the position information of the first sensor point is the 8th column and the 1st row, recorded as coordinates (8, 1); the position information of the second sensor point is the 4th column and the 2nd row, recorded as coordinates (4, 2), and the position information of the third sensor is the 4th column and the 3rd row, recorded as coordinates (4, 3).

[0051] It is further pointed out that the control module compares the time difference between the first center of gravity coordinate and the second center of gravity coordinate at the current moment of completing the alternating fall with the time difference at the previous moment of completing the alternating fall. If the time difference at the current moment is less than the time difference at the previous moment and the state continues to exceed the set acceleration duration judgment threshold, the control module controls the execution module 5 to accelerate the action; if the time difference at the current moment is greater than the time difference at the previous moment and the state continues to exceed the set deceleration duration judgment threshold, the control module controls the execution module 5 to decelerate the action, wherein the acceleration duration judgment threshold and the deceleration duration judgment threshold are set according to actual needs to increase the accuracy of the judgment.

[0052] When the control mode is entertainment mode, the control module generates a corresponding left virtual interaction indicator in the virtual entertainment interface according to the position information corresponding to the user's left foot area, and at the same time generates a corresponding right virtual interaction indicator in the virtual entertainment interface according to the position information corresponding to the user's right foot area. Among them, the left virtual interaction indicator and the right virtual interaction indicator can be set with multiple corresponding functions in the virtual entertainment interface according to actual needs, and can realize various specific performances such as clicking, dragging, and jumping, which is equivalent to a mouse pointer or keyboard, and the conversion control technology is relatively mature and is widely used in VR game equipment and infrared remote control interactive equipment.

[0073] Step S7: When the user steps onto the treadmill belt again, the array pressure sensor 2 collects pressure signals from the associated areas corresponding to the user's two feet and sends them to the control module. If the control module detects that the collected pressure data and position information match the recorded identification template, the corresponding reference running plan is displayed to the user. If the control module does not detect that the collected pressure data and position information match any of the recorded identification templates, the process returns to step S1 and repeats.

[0074] Among them, the matching of the pressure data and position information collected this time with the recorded identification template refers to the comparison of the pressure data of each sensor point with the recorded average value of the sensor point at the corresponding position in a certain identification template. If the proportion of sensor points whose differences are within the allowable error range to the sensor points in the entire pressure area is greater than the set matching percentage, the identification template is judged to match the currently collected pressure data.
