The present invention relates to a film pressure sensing device and a pressure sensing system for an exercise equipment. Specifically, the film pressure sensing device of the present invention may be installed on a component of an exercise equipment to sense pressure generated by a user contacting the component, generate a sensing data in response to the sensed pressure, and transmit the sensing data to an electronic device, thereby controlling an application program executed on the electronic device by operating the exercise equipment.
With the change of social style, indoor exercising have become more and more popular in recent years, and people have paid more attention to various demands of indoor exercising. For indoor exercising, most people choose to exercise in the gym, sports center or at home with their own exercise equipment. However, the exercise equipment currently in use is mostly limited to data sharing or video chatting between users, but does not provide motion sensing interactive applications in real-time. Gradually, users may lose their motivation to exercise with indoor exercise equipment as time goes by. Although, replacing the existing exercise equipment with new equipment providing built-in motion sensing function might help the previously mentioned problem, home users or gym operators would have to bear extra high costs accompanied with recycling issues for the replaced exercise equipment.
Accordingly, an urgent need exists in the art to improve the intelligent function of the exercise equipment at low cost and without replacing the exercise equipment, thereby increasing the user's motivation to use the exercise equipment.
Provided is a low-cost and highly interactive reconstruction scheme so that users can have real-time motion sensing interactive applications without replacing exercise equipment. Therefore, users are provided with new interactive experience without replacing the old exercise equipment, and the users' motivation to use the exercise equipment is increased.

The pressure sensing system 100 comprises one or more film pressure sensing devices 1 and an electronic device 2. Due to layout limitation and for simplicity of explanation,
The processing module 13 is electrically connected to the film pressure sensing elements 111-11n via a plurality of conducting wires L1-Ln, and is configured to receive the pressure sensing signals 101-10n. The processing module 13 generates a sensing data 140 according to the pressure sensing signals 101-10n and transmits the sensing data 140 to the electronic device 2. The sensing data 140 may include pressure values sensed by each of the film pressure sensing elements 111-11n (e.g., quantized values of changes of capacitance values). It shall be emphasized that, the film sensing module 11 of the film pressure sensing device 1 of the present invention is flexible and the thickness thereof may be less than 1.4 mm, so the film sensing module 11 may be tightly disposed on a component of the exercise equipment 300. The component of the exercise equipment 300 corresponds to a part of a user's body. For example, the component may be a saddle 31, a handlebar 33 or foot pedals 35a and 35b. Therefore, the specific position on the exercise equipment 300 described above may be a position on one of a saddle 31, a handlebar 33 and foot pedals 35a and 35b of the exercise equipment 300.
The handlebar of the exercise equipment 300 may have a plurality of specific positions, for example, a left upper handlebar, a left flat handlebar, a right upper handlebar, a right flat handlebar, and other different positions. Multiple groups of the film sensing modules 11 of the present invention may be simultaneously installed respectively on different positions (e.g., the saddle 31, a plurality of handlebar positions, and the foot pedals 35a and 35b, etc.) of the exercise equipment 300. In some embodiments, the film sensing module 11 may be designed with an installation kit that is convenient for installation according to different position requirements. For example, a seat cushion is designed for the saddle 31 and the film pressure sensing elements 111-11n are arranged on front, middle, left, right and other positions of the seat cushion, or a handlebar sleeve that is elastic and convenient for disassembly is designed for the handlebar position, and the film pressure sensing elements 111-11n are arranged on positions where the handlebar sleeve may be grasped by hands of a person.
For example,
The processor 13 may be any of various processors, central processing units (CPUs), microprocessors, digital signal processors, or other computing devices known to those of ordinary skill in the art. Transceiver 137 may be a Bluetooth transceiver or any short-range communication transceiver. Therefore, a user can construct the pressure sensing system 100 of the present invention simply by pairing and connecting the film pressure sensing device 1 and the electronic device 2 (e.g., through Bluetooth pairing).
The I/O interface 133 has a plurality of VCC (Voltage Common Collector) pins P1-P4 and a GND (ground) pin P5 to be electrically connected to the film pressure sensing elements 111-114 via conducting wires L1, L2, L3, L4 and LG. The processor 135 receives the pressure sensing signals 101-104 from the film sensing elements 111-114 through the I/O interface 133, and generates sensing data 104 according to the pressure sensing signals 101-104. Next, the processor 135 transmits the sensing data 104 to the electronic device 2 through the transceiver 137.
The film sensing module 11 further comprises an insulating layer IL. The insulating layer IL may be a PET shrink film. The insulating layer IL has a first surface S1 and a second surface S2. The film pressure sensing elements 111-114 respectively have first conductive layers 111a, 112a, 113a and 114a disposed on the first surface S1 of the insulating layer IL and second conductive layers 111b, 112b, 113b and 114b disposed on the second surface S2 opposite to the first conductive layers 111a, 112a, 113a and 114a. The first conductive layers 111a, 112a, 113a and 114a of the film pressure sensing elements 111-114 are electrically connected to the VCC pins P1-P4 respectively, and the second conductive layers 111b, 112b, 113b and 114b of the film pressure sensing elements 111-114 are electrically connected to the GND pin P5.
In this embodiment, the first conductive layers 111a, 112a, 113a and 114a, the second conductive layers 111b, 112b, 113b and 114b as well as the conducting wires L1, L2, L3, L4, and LG of the present invention may be formed by printing conductive silver paste. However, as shall be appreciated by those of ordinary skill in the art, in other embodiments, the first conductive layers 111a, 112a, 113a and 114a, the second conductive layers 111b, 112b, 113b and 114b as well as the conducting wires L1, L2, L3, L4 and LG of the present invention may also be formed by printing other conductive materials (e.g., conductive ink).
Moreover,
It shall be noted that, the shapes of the film sensing modules 11 depicted in
In an embodiment, the film sensing module 11 may further comprise an anti-interference layer. The anti-interference layer may also be formed by printing conductive silver paste and formed into a net shape. The anti-interference layer is configured to cover the second conductive layers of the pressure sensing elements and is electrically connected to the GND pin to form a ground net.
In an embodiment, the film sensing module 11 may further comprise a encapsulation layer. The encapsulation layer is used to encase the insulating layer, the pressure sensing elements and the anti-interference layer to increase the protection or beauty of the outer layer of the film sensing module 11. The encapsulation layer may be formed from any insulating material.

When each film pressure sensing element senses pressure to generate a pressure sensing signal, the display interface 21 changes the state of the corresponding object on the calibration image 201. For example, as shown in
Please refer to
For example, the application program may generate an animation 202 for a moving bike BK and is displayed in the display interface 21 and may accept the control command of the application program for operation. As mentioned above, the sensing data 140 may include pressure values sensed by each of the film pressure sensing elements 111-11n. Therefore, according to the sensing data 140 received from each film pressure sensing device 1, the application program may generate a control command to control a turning angle of the moving bike BK in the animation 202. It is conceivable that when the film pressure sensing device 1 installed on the left foot pedal 35b senses a larger pressure as compared to the film pressure sensing device 1 installed on the right foot pedal 35a, the control command generated by the application program controls the bike BK to turn left, and the turning angle to turn left may be calculated according to the difference between the two pressures.
For another example, similarly, the animation 202 may also show other characteristics of the moving bike BK. For example, according to the sensing data 140 received from each film pressure sensing device 1, the application program may generate a control command to control a lean angle when the moving bike BK is turning. Similarly, it is conceivable that when the film pressure sensing device 1 installed on the left foot pedal 35b senses a larger pressure as compared to the film pressure sensing device 1 installed on the right foot pedal 35a, the control command generated by the application program controls the moving bike BK to lean to the left, and the lean angle to the left may be calculated according to the difference between the two pressures.
In addition, in the above exemplary example, when the film pressure sensing device installed on the exercise equipment 300 senses different pressure distributions, the application program may generate different control commands to make a virtual person VM riding the bike BK in the animation show corresponding actions or postures. For example, when the film pressure sensing element on the saddle 31 has not sensed pressure but the film pressure sensing elements of the foot pedals 35a and 35b has sensed pressure, the virtual person VM riding the bike BK in the animation may show a standing riding posture; and when the film pressure sensing element on the saddle 31 has sensed pressure, the virtual person VM riding the bike BK in the animation may show a sitting posture. It shall be noted that, the animation 202 generated by the application program in this embodiment is illustrated by showing the moving bike BK. However, in other embodiments, the animation 202 generated by the application program may also provide users with various choices when being applied to different exercise equipment 300, e.g., a moving motorcycle or a virtual person who is climbing a mountain.
According to the above descriptions, the film pressure sensing device 1 of the present invention may be installed on various exercise equipment 300 and used in combination with specific electronic devices 2 (e.g., a tablet and a smart TV) to construct the pressure sensing system 100 of the present invention. By executing the application program and receiving the sensing data 140 from the film pressure sensing device 1 by the electronic device 2, the present invention may enable users to have real-time motion sensing interactive applications without replacing exercise equipment. Therefore, the present invention not only enables users to have new interactive experience without replacing the old exercise equipment, but also increases the users' motivation to use the exercise equipment.
The above disclosure is related to the detailed technical contents and inventive features thereof. People skilled in this field may proceed with a variety of modifications and replacements based on the disclosures and suggestions of the invention as described without departing from the characteristics thereof.
