Definitions
- the subject of the patent is a digitalization and motion estimation device, which, in comparison with previously known devices, can in many respects make more accurate surveys or create motion files even without an external reference signal.
- a data processing program is closely connected with the device as a hardware tool.
- An important element of the device is a network of sensors strengthened immediately on the body and operating on an inertial basis, based on the signals of which a data processing program with simultaneous evaluation of the results displays the spatial motion of the body under study.
- the device can be used for ergonomic analysis, for creating motion animations, in know-how, in healthcare, for analyzing the actions of athletes, or for other purposes.
- Markers in their simplest form can also be inertial sensors mounted on body parts that are separately moving units. In this case, there is no need for external means of observation, and from the signals of the sensors, you can create a vector skeleton, which, based on the angular position of the individual extremities, is uniquely determined.

- US2007250286 sensor system AP - Motion Monitoring and Analysis System
- This device is recommended to be used to check the physical condition (mainly the spine) of physical workers, which The signals from the sensors on the feet do not participate in the calculation of movements, since the displayed model, by the nature of the field of application, does not perform movement to change places and there is no need to take them into account.
- US2013217352 (A1) - SYSTEM AND METHOD TO PREDICT AND AVOID MUSCULOSKELETAL INJURIES
- Our goal was to exceed the capabilities of well-known digitalization and motion estimation systems based on inertial sensors, mainly in the area of more accurate imaging, including more accurate tracking of movements in relocation.
- Our further goal is more accurate tracking, recognition of static and dynamic states, as well as achieving the highest possible degree of independence.
- our goal is to simultaneously check the external forces on the primary contact surfaces of the body (feet, hands) with the determination of the position of the body, because this gives important information mainly in industrial, ergonomic applications.
- the solution we recommended is based on the realization that the signals used for other purposes (mainly for measuring the load) of devices can be perfectly used also for analyzing movements. With their help, you can more accurately determine that when the legs are stable on the ground, and the distance traveled can also be more accurately measured, as before. With pressure sensors, you can easily determine whether a person is currently standing on the ground with two legs, you can set whether it is in a static or dynamic position, then by the difference in pressure on the heels and on the toes, you can even more accurately determine the moments of changes in the legs. The proposed system can distinguish between moments when the front third of the foot is on the ground and when the heel is in this way, we can obtain more detailed information about the walking process than from previous systems.
- the subject of the proposed patent in this way is a digitalization and motion estimation device, which consists of inertial measuring modules, a control unit, a data storage unit, and cable or wireless connections between them fixed on separately moving parts of the body or parts of the person under study.
- a further characteristic property of the device is that, in the case of modeling human movement, in addition to measuring modules on the thighs, legs, feet, shoulders, forearms, hands, head, hips and torso, there is at least one measuring module on the back near the spine, then one measuring module on the feet is connected to the measuring modules on the feet, and one connected to the measuring modules on the hands glove for measuring pressure. Measuring molles for the hips and measuring modules for the spine are mounted on the back of the user.
- Most measuring modules are general purpose measuring modules.
- Each general-purpose measuring module contains at least one triaxial acceleration sensor, at least one triaxial sensor of acceleration acceleration, an internal data bus, one triaxial tuning magnetometer and an interface to the control unit.
- the measuring modules for the feet have two triaxial acceleration sensors, two triaxial angular acceleration sensors, a triaxial tuning magnetometer, one interface to the control unit and analog-to-digital converters in the amount corresponding to the number of pressure sensors connected to the measuring module of this foot.
- Each analog-to-digital converter is associated with only one pressure sensor.
- the measuring modules for brushes have one triaxial acceleration sensor, one triaxial angular acceleration sensor, one triaxial tuning magnetometer, analog-to-digital converters in the amount corresponding to the number of glove pressure sensors connected to the measuring module of this brush and one interface to the unit management. Each analog-to-digital converter is associated with only one pressure sensor.
- the control unit contains one central processor, one real-time clock circuit with an autonomous power supply, one data storage device, one USB connector, and one interface in the direction of the measuring modules.
- the internal functional modules of the control unit are interconnected with the data bus.
- An advantageous solution for constructing the device may be such a design in which all the interfaces between the control unit and the measuring modules are made in the form of radio frequency communication units.
- the control unit is advantageously equipped with at least one external bus connector.
- the modules on the feet have a third pressure sensor located under the metatarsal bones.
- the next advantageous embodiment of the device is characterized in that at least part of the measuring modules has an independent internal processor, these internal processors are connected to acceleration and angular acceleration sensors, magnetometers, analog-to-digital converters directly or via internal data buses.
- control unit constitutes one mechanical unit with a hip measuring module, and is fixed near the spine in the thigh area, it is advisable with the help of a hip belt or by integration into a part of clothing worn on the body.
- the interface is implemented in the form of cable connections, we consider it expedient to conduct the cables between inertial modules and the control unit through an adjustable cable holder.
- the adjustable cable holder holds the cable tightly at several points, and through it the cable is routed so that it forms two open loops lying opposite each other, with the tension of the two free ends of the adjustable cable holder, the size of the loops is reduced.
- Measuring modules (general purpose) between the shoulder blades and in the middle of the back are expediently mounted on such a tape vest, which consists of a chest circumferential tape and diagonal cross ribbons adjacent to the back.
- the two lower ends of the diagonal cross ribbons are attached to the circumferential tape under the armpits, and their upper ends through the shoulder are held down over the breasts and are joined to the circumferential tape in its front part or in the part under the armpits.
- the interscapular measuring module is fixed at the intersection of the lower and upper ends of the cross tapes, and the measuring modules for the middle of the bottom are fixed on the back of the circumferential tape.

- FIG. 1 shows our proposed location of the measuring modules in accordance with the execution of the control unit 1 according to the seventh independent clause of the application, where the control unit 1 is mechanically connected to one vertebral measuring module, it is advisable with the femoral measuring module.
- the measuring module of the left foot 15 is fixed, on the left lower leg the measuring module of the left lower leg 14, and so on, in accordance with the names and the figure, the measuring module of the head 4, the upper measuring module of the left shoulder 5, the lower measuring module of the left shoulder 6, the measuring module left forearm 7, measuring module of the left hand 8, upper measuring module of the right shoulder 9, lower measuring module of the right shoulder 10, measuring module of the right forearm 1 1, measuring module of the right hand 12, meter left thigh module 13, right thigh measuring module 16, right tibia measuring module 17, right foot measuring module 18, and second spine measuring module 2 and third spine measuring module 3.
- measuring modules are general-purpose measuring modules, which makes it possible to use more a simple and identical design, but the designs of the measuring modules 8 and 12 for the hands, the measuring modules 15 and 18 for the feet, and in this case one of the measuring modules for the spine are different from them, partly in order to achieve more accurate observation, partly because of the connected peripheral devices.
- Figure 1 shows that the movements of the body are displayed with measuring modules one more than usual, and that the measuring modules are not installed on the stomach.
- the measuring modules are shown together with their connections.
- This figure presents new information, which is that the interface 31 is made in the form of cable connections. Interface 31 means all the connections between the individual measuring modules, or between them and the control unit 1.
- 19 and 20 feet modules are connected to the measuring modules 15 and 18 of the feet, and gloves are connected to the measuring modules 8 and 12 of the hands 21 and 22 for measuring pressure.
- Figure 3 shows a simpler internal circuit of general-purpose measuring modules. These measuring modules consist of one triaxial acceleration sensor 24, one triaxial angular acceleration sensor 25, one triaxial tuning magnetometer 28, and they are connected inside the measuring module to the interface 31 through which they can be connected to the control unit 1.
- the dashed line shows the secondary triaxial a magnetometer 26, which, strictly speaking, is not needed for operation, but since the common sensor modules released for these purposes, this module contains, so we show it. In industrial conditions, this magnetometric method is unreliable, so we do not use signals from them.
- Figure 4 shows the internal circuit of the measuring modules, which are also equipped with an internal processor 40.
- One triaxial acceleration sensor 24, one triaxial angular acceleration sensor 25, one triaxial tuning magnetometer 28, and one secondary triaxial a magnetometer 26 are connected via an internal data bus 27 to an internal processor 40, which preprocesses the sensor signals and then transfers data to the control unit 1 through an interface 31 connected to it .
- Figure 5 shows the internal structure of the integrated control unit.
- the functions of the measuring module in accordance with the performance of the general-purpose measuring module are performed by one triaxial acceleration sensor 24, one triaxial angular acceleration sensor 25, and one triaxial tuning magnetometer 28 under the control of a high-power central processor 23.
- the central processor 23 is further connected to the contour of the real-time clock 32, which is expediently equipped with autonomous power supply (for example, using a supercapacitor), and has the function of accurately dating the shots even in case of offline operation.
- the triaxial tuning magnetometer 28 helps in orientation and fine tuning at the start of the measurement, but is no longer needed during the measurement.
- the control unit 1 is advantageously equipped with a radio frequency communication unit 29, as well as with a USB module 33, which could carry out external data transfer, as well as communication in the direction of the measuring modules.
- the radio frequency communication unit is most simple to implement in the form of a wifi block, but for knowledgeable specialists it is obvious that other methods of radio frequency data transmission can be used.
- the data storage device 30 is used to store filming, and makes it possible to use the device in island mode.
- the data storage device is a removable SD memory card. Communication with measuring modules 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 is provided by interface 31 (in simple cases this direct cable connection).
- a connector is provided.
- an external data bus 37 which is also connected to the central processor 23.
- FIG. 6 shows the structure of the measuring modules for brushes 8 and 12. A significant difference between them and general-purpose measuring modules is. that gloves 21 and 22 are connected to the measuring modules 8 and 12, for measuring pressure, each of which contains at least three, but seven pressure sensors 44 are better for the corresponding measurement, the signals from each are received with their analog-to-digital converter, which signals are transmitted to the internal processor 40 .
- FIG. 7 shows the structure of the measuring modules of the feet 15 and 18.
- the structure of the general-purpose measuring modules was taken as the basis, but for a more accurate observation of movements when changing places, a double set of inertial sensors is used, it is advisable in the form of two triaxial acceleration sensors 24, two triaxial angular acceleration sensors 25, (and, noticing in passing, one triaxial tuning magnetometer 28, but this, as already noted, for external reasons of material supply), which are through internal of the data bus 27 are connected to the internal processor 40.
- the foot modules 19 and 20 are connected to the stop measuring modules 15 and 18, and the signals from the pressure sensors 44 built into them are in this case also received by analog-digital converters 38, the number of which corresponds to the number of pressure sensors .
- a useful element of the device is the left glove shown in Figure 8 for measuring pressure 21. According to our proposal, it is advisable to install pressure sensors 44 from the inside on the thumb, on the index and middle fingers, and also on the palm. A sensor of the type FSR408 was found suitable for this purpose. Using pressure sensors 44, it is possible to accurately estimate the gripping force and accurately measure the gripping time. Palm pressure measurement on seven surfaces meets all criteria for ergonomic systems.
- Figure 9 shows the inside of a higher resolution glove containing a total of fourteen pressure sensors 44. Here, with the exception of the little finger, almost all phalanges have one pressure sensor 44, then there are also three large size sensors 44 on the palm, and at the same time providing a real, ergonomic grip feel and high precision measurement. Some sensors, e.g. which are located on one finger, or in the palm of your hand, is not connected separately, but in parallel to one analog-to-digital converter.
- Figure 10 shows the left measuring module for foot 19 from the bottom.
- Module 19 for the feet it is advisable to perform in the form of an insert that can be put in shoes, or installed on the sole of the shoe.
- the measuring module 19 for the foot for the implementation of the developed method of step research that we have proposed, it is necessary to install at least one pressure sensor 44 under the toes and one under the heel, but it is even more advisable to install a third sensor under the metatarsal bone.
- the measuring module 19 shown in Figure 11 for the AXS-TA1.0 type feet can be inserted into shoes, as it is soft and pressure sensors 44 are integrated into the fabric.
- Such shoe insert provides comfortable and ergonomic wearing.
- Such a shoe insert can be created in a film version or in a version with conductive threads.
- we attach a pressure-sensitive conductive film to a flexible circuit board we attach a foam layer (preferably made of neoprene) to it, and in the second case, we install a pressure-sensitive conductive film between two outer foam layers so that between the foam layers and the sensitive the pressure of the conductive film is a layer (fabric) with conductive threads.
- Figure 12 shows the cable holder 39 in working condition.
- the connections between the measuring modules can be either cable or wireless.
- the connections between the measuring modules can be either cable or wireless.
- the first case if we want to provide the possibility of using it in a wide range of sizes, then in the case of models with smaller dimensions there is a large number of free-moving cables on the subject's body, which is disadvantageous from the point of view of labor protection.
- On two edges of the cable holder 39 there is one clamping groove 42, in which, according to Figure 12, you can fix the cable section of the desired length - up to half a meter, then through the middle hole you can draw the middle branch of the cable.
- the cable holder 39 is expediently made of two halves. With the tension of the free branches, the dimensions of the 39 open loops enclosed by the cable holder decrease, with this, the free lengths of the cables can be increased, and with the tension of the loops, the opposite effect can be achieved.
- Figure 13 shows the cable holder on the side.
- the cables pressed in the pressure grooves 42 can be moved by manual force.
- Hole 43 for cables is available with unmounting (snapping) of the lower and upper halves of the holder.
- Cable holders can be of another design, e.g. pre-tensioned cable drum.
- the task of the tape vest shown clothed in figures 14 and 15 in front and behind is. so that he holds pressed to the body on his back (mainly near the spine) the second measuring module 2 for the spine and the third measuring module 3 for the spine.
- the waistcoat consists of an adjustable circumferential tape 34 around the body below the breasts and connected with it and adjacent to the back of the diagonal cross ribbon.
- the two lower ends of the cross ribbon are docked with the circumferential ribbon 34 under the armpits, and its upper ends 35 pass through the shoulders down above the breasts and are connected to the circumferential ribbon 34 or to front part, or under the armpits.
- the measuring modules are fixed at the intersection of the lower ends 36 and the upper ends 35 of the cross ribbon, and on the back of the circumferential tape 34. Due to the increase in the number of measuring modules 1, 2, 3 for the spine to three, and the stabilizing effect of the tape vein, unlike previously known solutions the rotation between moss-THY2 and Thl l-Th4 can also be accurately detected.
- the measuring modules 1, 2, 3 all lie directly on the spine, and not one of them is located in front of the chest, so the measurement results are more accurate than with technologies in which one of the three measuring modules is located on the front of the chest.
- the digitalization device data processing program and motion estimation data from the data hardware collected and prepared by the control unit moves a simplified virtual bone system in three-dimensional space, while being able to represent the survey even in real time, and in case of deviation from the preset normal values give a warning with color with an encoding depending on the deviation value, or in offline mode after shooting, immediately reproduce the movement and evaluate it according to the specified characteristics m.
- the data processing program is expediently used on a separate, more powerful device (for example, PC, tablet, etc.), to which data can be received via cable communication, via wireless communication or on a hardware unit removed from the control unit and put into the program executing the program data carrier.
- the applied mathematical model takes into account the relative shifts (delta) relative to the initial state (initial position), which are produced from the differences in the angular shifts of individual bones.
- the forward direction is fixed at attention (starting position).
- the midpoint of the hips in the starting position is the starting point of the coordinate system of the digitalization and motion estimation system.
- a “model” is formed by a combination of initial directions and distances (vectors). In the case of using a special magnetometer of the control unit, it is possible to orient the main direction of the model relative to the north direction.
- Correction shooting is used to eliminate errors due to dressing and for subsequent correction of measurement errors.
- the extremities and the spine are upright, the shoulders and feet in a horizontal position. Based on the gravitational vector, you can measure the discrepancies, inclinations relative to the horizontal and vertical, so the error due to dressing can be corrected.
- the person performing the calibration coordinates the operation of the sensors.
- the digitalization and motion estimation program can work and give accurate results without magnetic orientation data.
- correction can be carried out in two ways.
- the first gravitational method is based on the applied vector system.
- the body is described as a continuous system of vectors, where the endpoint of individual vectors is the starting point of the next vector, and when the rotations are implemented, the processing of the endpoints proceeds continuously.
- individual elements of the vector system are rotated in a vertical position relative to the direction of gravity.
- the second method with the rotation method, the discrepancies are corrected with the "reverse rotation" of the difference of angles seen with using additional or subsequent special corrective movements.
- the used mathematical model differs from the methods described so far, the processor ICs used after the internal fusion of data give out a quaternion. Pre-filtering and fusion of IP data is performed by itself.
- Qicb quaternion Compensation base for bone i.
- Mi transformation matrix 4x4 for bone i.
- Mprev calculated value Mi for the bone in front of it in the kinematic chain
- the procedure for calculating bones occurs after their kinematic alternations.
- the femur is selected first, all other bones are calculated relative to it.
- the identity matrix, Qprev [1,0,0,0].
- the proposed digitalization and motion estimation device it is possible to digitalize the movement of any living or moving body. It can be used everywhere, regardless of geographical location, in water, underground, in the air, since it can record data autonomously, without any external device, and the number of subjects for simultaneous shooting is also unlimited. It can be used in conditions of magnetic (electromagnetic, ferromagnetic) interference, then in stand-alone mode it can work without creating radio frequency interference, therefore it does not interfere with the work of other devices using radio frequencies located in the vicinity.
