The invention relates to a system and method for posture and movement regulation. Furthermore, the invention relates to a method for posture and movement regulation for humans, in particular by using a system according to the invention. Moreover, the invention relates to a computer readable storage medium.
Persons who suffer from walking disorders and/or balance disorders and/or postural disorders, or who are restricted in their mobility due to operations, are usually very insecure during walking. These persons often adopt protective postures. This may intensify postural damage.
It is the task of the present invention to specify a system for posture and movement regulation so that at least the group of persons described above regains more safety when walking or moving. The system is intended to help prevent accidents involving persons with an unstable gait. Additional safety is to be provided for persons with an impaired sense of balance. In particular, protective postures and an antalgic gait as well as incorrect and unhealthy movements or sequences of movements are to be avoided. Moreover, in the event of only one-sided body posture damage and/or gait disorders, the system for body posture and movement regulation should make it possible to act specifically on this one-sided disorder.
Furthermore, the system should make it possible to consciously and correctly carry out training sessions in case of changes in position, rotation, and posture of bodies or individual body parts to be trained. The system should serve as a training means, for example, to improve joint mobility or to improve mobility in the event of muscle shortening or weakness in individual limbs or in case of movement restrictions in individual limbs or groups of limbs. Therapy goals with a therapist should be accelerated, simplified or intensified by applying the inventive system.
Moreover, it is the task of the present invention to specify a method for posture and movement regulation for humans. The method should preferably be performable with the system according to the invention.
The task of the invention is accomplished by a system for posture and movement regulation in accordance with the teachings set forth herein.

The at least one position sensor, in particular the at least one body position sensor unit, is preferably arranged or fixed in the area of the user's solar plexus. In a particularly preferred embodiment of the invention, the at least one position sensor, in particular the at least one body position sensor unit, is arranged or fixed in the area of the manubrium.
The formation of the carrying device as an upper body garment is particularly suitable for forming multiple position sensors and arranging them at different positions and/or body parts of the user. Moreover, with the help of such a formed upper body garment, an output unit for outputting a vibration signal with multiple vibration generators can be formed. The vibration generators can be arranged at different positions and/or on different parts of the user's body.
A further formation of the carrying device can be formed stocking-like or band-like.

In another embodiment of the invention, it is possible to form the carrying device glove-like.
In another embodiment of the invention, it is possible to form the carrying device as part of a shoe or shoe-like.
The formation as an eyeglass adapter is also possible. Provided that position sensors are attached to eyeglasses, the user's head posture can be detected or monitored in particular.

Such a magnetic attachment is preferably carried out by means of two magnets, with the user's clothing located between the two magnets. In this context, the user's existing clothing can serve as a kind of carrying device, whereby the clothing can be changed regularly.

In a further embodiment of the invention, the inventive system may comprise an audio module. This audio module is preferably formed between the arithmetic unit and the output unit for outputting an acoustic signal.
In a particularly preferred embodiment of the invention, the audio module preferably comprises at least one tone generation unit and at least one audio mixer unit. In other words, the tone generation unit is the audio source. Using the tone generation unit, the fundamental tone of the at least one acoustic signal can be generated. This can be done in the form of a synthesizer or tone generator. The formation of an audio player is also possible. For example, audio files may be stored. In other words, it is possible to select from multiple stored tone sets of an audio player. However, it is also possible to generate an individual tone by means of a tone generator.
For example, it is possible for the tone to be generated on the Internet, in particular on a server, and streamed, in particular retrieved and received, by the arithmetic unit of the system and/or the audio module. This can be done, for example, via an Internet audio player, where the body position sensor unit and the audio mixer unit generate the acoustic signal, preferably in real time.
The audio mixer unit serves for forming sound effects and for converting sound. This can affect both the pitch and the tone phases. In particular, the stereo volume of the individual channels is controlled using the audio mixer unit.
For example, it is possible that the signal generated by the audio mixer unit is also generated on the Internet, especially on a server, and streamed by the arithmetic unit and/or the audio module. In terms of procedure, this can be done, for example, such that the arithmetic unit sends the body position data determined by the body position sensor unit to a server. Audio mixing and/or tone generation and/or conversion of body position data can be performed on a server. The acoustic signal can be streamed, in particular retrieved and received, by the system's arithmetic unit and/or the audio module.
The system may also comprise a monitoring unit, in particular an external monitoring unit. This monitoring unit can be formed as a mobile communication device. The, preferably external, monitoring unit preferably comprises a control unit and a display unit. The display unit serves for visually displaying the data determined by the body position sensor unit. The control unit preferably serves for setting system parameters. The monitoring unit enables third parties, such as doctors or trainers, to monitor the application of the inventive system and intervene (in real time) with the application. Here it is possible that the system parameters are changed by external persons such as doctors or trainers.
With the help of the inventive system, it is possible, for example, to control the posture during sitting, in particular during longer periods of sitting. Thus, a correct sitting posture can be enabled. Furthermore, rehearsed or defined movement sequences, in particular in gait and posture, can be checked. The person can be given feedback so that the correct execution of the movement sequence and/or the movement sequence of individual limbs and/or an exercise is made possible even without the presence of a therapist and/or a doctor.
In yet a further embodiment of the invention, the system may comprise storage. The storage can be a local storage. This local storage is preferably integrated into the arithmetic unit of the system. Furthermore, it is possible for the storage to be an external database, in particular a cloud. The data collected by the body position sensor unit can be stored and/or transferred in the database. The external database can also be called a platform.
The system can also have a communication unit. With the help of the communication unit, collected data can be transferred to the database, in particular to a cloud or an online database or a web server. Furthermore, the communication unit is preferably configured such that data can be retrieved from a cloud, an online database or a web server and imported into the system, in particular into the arithmetic unit. This is data such as software updates, software upgrades, new tones and predefined presets and/or setting options.
The inventive method for posture and movement regulation for humans can also be described as a method for walking and movement regulation aid. Since the regulation of movement comprises a regulation of walking and gait and, furthermore, a regulation should also be enabled when the user is standing still, namely a regulation of posture, the method for walking or gait and movement regulation aid is referred to in the following as a method for posture and movement regulation for humans.
The inventive method is performed in particular by applying a system according to the invention. The inventive method for posture and movement regulation comprises the following steps:
Preferably, the inventive method is performed with the inventive system described above.
Steps a) to d) are preferably repeated infinitely while the inventive system is being carried. Step a) is preferably performed with the help of a/the body position sensor unit.
In step c), a comparison of the position data, in particular of the body position data, with target position data, in particular target body position data, may be performed. This step c) is preferably performed with the help of an arithmetic unit.
Prior to step a), a calibration step may be performed, in which the 0° position, in particular the 0° body position data, of the human body, in particular the 0° inclination of the human body, is determined.
Among other things, a calibration step is necessary to enable persons with a leaning basic body posture to use the inventive system as well. Moreover, the device is to be attached to the body quickly. However, since in most cases the device cannot or will not be mounted 100% vertically, it is necessary to determine the 0° position of the human body in the context of a calibration. In particular, the 0° position of the human body or the 0° inclination of the human body can be determined as a mean value. As an alternative, it is possible to set the absolute perpendicular as inclination grade 0.
In particular, the comparison of body position data with target body position data preferably performed in step c) can be performed on the basis of the 0° position of the human body determined in the calibration step. The target body position data can thus correspond to the 0° position of the human body, in particular the 0° inclination of the human body.
Prior to step a), in particular prior to the calibration step, a setting step (setting mode) can be performed. In the setting step, for example, presettings of the system can be made without prior positioning of a position sensor, in particular a body position sensor unit. Such settings are no longer possible or very difficult to make during the actual determination of the body position data and during movement.
In the course of the setting step, it can first be defined at which degree of inclination 1 (n1) an acoustic signal should be output. Furthermore, it is possible to define a degree of inclination 2 (n2) in the setting step, at which a maximum volume or an alarm tone in the form of an acoustic signal is output. Furthermore, it is possible to preset the system parameters such that a quickly responding and possibly loud or hard signal should be output or that a gently rising acoustic increase in one or both ear(s) should be generated. Furthermore, it is possible to set the overall volume separately, which is stored in a storage after setting the system parameters.
Preferably, at least two presettings are made in order to convert only the individual and relevant range of motion or inclination of the human body into signals, in particular into acoustic signals.
This is a first sensor value, which for example corresponds to a first inclination value. The first sensor value (n1) defines the smallest sensor value that must at least be exceeded in order to start an acoustic signal and/or an acoustic increase.
A/the second sensor value (n2) can correspond to the second inclination value. The second sensor value defines the maximum sensor value at which an acoustic increase is to be reached maximally. An acoustic increase is to be understood, for example, as the pitch or volume of the acoustic signal. In this context, sensor values thus are values to be detected by means of a sensor.
The two sensor values (n1, n2) can each be determined or defined for a movement to the left and to the right. The two sensor values (n1, n2) can each be determined or defined for a movement forward and backward.
This allows the sensor values (n1, n2) to be determined or defined from two sides, i.e. for left and right or for front and rear symmetrically to a mean body reference axis. This means that the two sensor values (n1, n2) are only determined for one side (e.g. left) and then the two sensor values (n1, n2) for the second side (e.g. right) are defined symmetrically to these.
In yet a further embodiment of the invention, it is possible to first determine the sensor values (n1, n2) for a first side and then for the second side. Thus, the sensor values (n1, n2) can be determined independently of each other with regard to the respective sides.
In a first embodiment of the inventive method, the presettings can be made in the setting step by means of a control unit. It is possible for the user to orient himself on possible settings or on a selection of predefined system parameters and thus to define the first sensor value (n1) and the second sensor value (n2).
In a further embodiment of the inventive method, it is possible that the setting step is not performed in the sense of a presetting to be typed in or a presetting to be selected from a multitude of presettings. The setting step is possible in this embodiment of the inventive method without sight of or without viewing a control unit. In this embodiment, the presetting or setting step can be performed by tapping on a control unit. In this process, the user orients himself on a real-time body inclination. While this real-time body inclination is performed actively by the user, a first sensor value and a second sensor value can be set each by confirmation on the control unit, i.e. by blind tapping. In this case, the control unit serves as a kind of response button, i.e. as a feedback button.
In step a), the body position data can be determined in the sagittal plane and in the frontal plane of the body. In this context, the sagittal plane refers to a plane extending from the head to the pelvis and from the back to the abdomen. The frontal plane is the plane of movement visible in a frontal view of the human being. In connection with the sagittal plane, the body position data thus is recorded in the sense of an extension from front to back or vice versa. In connection with the frontal plane, the body position data is recorded in an extension from left to right or vice versa.
In step c) a first acoustic signal can be generated for the body position data in the frontal plane and a second acoustic signal for the body position data in the sagittal plane. In other words, when the body is inclined to the left or right, a first acoustic signal, in particular a first tone, in particular a first stereo sound, can be generated. When the body is inclined forwards or backwards, a second acoustic signal, in particular a second tone, particularly preferred a second stereo sound, can be generated.
In other words, a tone in the respective ear, i.e. in the left or right ear, that increases with the degree of inclination within a defined range, and an additionally changing stereo sound character (front, back) can be used to intuitively inform the user acoustically in real time in which direction and to what extent the body's inclination is currently formed. Depending on the presettings, the tone may increase slowly or quickly.
It is possible to create a so-called base tone. Such a base tone is output via the output unit for outputting an acoustic signal even if there is no deviation from the 0° position of the human body, in particular no deviation from the 0° inclination of the human body. The volume of the base tone can be extremely low. A base tone is used to perceive the generated tone differences more sensitively. Moreover, the base tone serves to achieve permanent system control. If no basic tone is output, the user can conclude that the system is not functioning or that there is a fault.
Preferably, the position data, preferably the body position data, is stored. Moreover, it is possible to send the position data, in particular the body position data, to a database.
The position data, in particular the body position data, can be stored in the inventive arithmetic unit. Moreover, it is possible for a mobile communication device to have a storage for storing the position data, in particular the body position data. The formation of an external storage is also possible.
If the position data, in particular the body position data, is sent to a database, it is preferably an external database. The database can be a cloud.
Furthermore, it is possible to save automatically captured data or to send it to a database. Automatically captured data may be, for example, the time and/or the date and/or the weather conditions and/or the temperature and/or a GPS signal and/or motion and vibration values and/or the distance traveled and/or the system usage time and/or the speed of movement and/or information on soil conditions and/or the system settings used, in particular the defined sensor thresholds. This makes it possible to correlate the stored body position data with external conditions.
Moreover, it is preferably possible to save manually created notes of the user or to send them to a database. Manually created notes may be, for example, the user's clinical picture and/or the user's current medication and/or the user's general health status. This allows an analysis mode to be performed. Therapy progressions can be recorded and optimized.
By means of a tone, which is associated with the degree of inclination of the body, in the respective ear of a user, the user, in particular of the inventive system, is informed acoustically in which direction the body is inclined and/or to which extent the body is inclined.
In other words, an acoustic signal, which is associated with the deviation of the body from the 0° position of the human body, in the respective ear of a user can inform the user in which direction the body deviates from the 0° position of the human body and/or how much the body position deviates from the 0° position of the human body.
The acoustic signal can also be a mute signal. If no tone, in particular no stereo acoustic signal, is output, the position/inclination of the body does not have to be corrected. The same applies to the output of a vibration signal. If the position/inclination of the body does not have to be corrected, it is possible not to output a vibration signal.
A first method for converting the body position data into an acoustic signal provides for a mono rise. If a changed acoustic signal is sent to an ear, in particular an acoustic signal which changes with regard to volume or modulation or with regard to effects, the position of the body must be corrected. If no acoustic signal is output by the output unit or only the base tone is output by the output unit for outputting an acoustic signal, the body position or the inclination of the body does not have to be corrected.
A further embodiment of step c), i.e. the conversion of the body position data into at least one acoustic signal, provides for a stereo change to be performed. Accordingly, when a 0° position of the human body is adopted, in particular a 0° inclination of the human body, a central, equivalent stereo signal is output to both ears of the user. In other words, a stereo signal is output in equal proportions to the left and to the right ear of the user. When the body position has to be corrected, in particular in case of an inclination of the human body to be corrected, the acoustic signal is increased in one ear and reduced equivalently in the other ear.
The inventive method provides in particular for an acoustic signal, in particular a second acoustic signal, to be output by the output unit also if the body position deviates forwards or backwards. The second acoustic signal can increasingly replace the first acoustic signal depending on predefined settings and/or depending on the actual degree of inclination.
Depending on the personal sensation of the user and the therapy goal, the acoustic signal can generate a kind of pressure resistance or a kind of suction effect on the user.
In a pressure resistance type method, the volume of the tone increases in that ear of the user to which side the user's body is inclined.
In other words, when the body is inclined to a first side, the volume of the tone in the ear of that first side increases. The tone thus signals the actual situation of the body position or the inclination status of the user's body.
After a familiarization period, the user perceives the acoustic signal output as an increasing resistance and an increasing warning.
In a suction type method, the acoustic signal is generated on the ear opposite the direction of inclination. After a familiarization period, the user perceives such an acoustic signal output as a soft, pleasant correction and less as a warning.
The pressure resistance type method or the suction type method can be performed alternatively or additionally with vibration signals.
In a further embodiment of the invention it is possible that in step a) the average direction of movement of the body and a deviation from the average direction of movement are determined. It is possible for a user to have a crooked gait pattern without the body position deviating from the 0° body position or the body being inclined in a certain direction. It is therefore possible for a user to deviate from the average direction of movement despite a straight upper body, in other words despite a straight posture, for example as a result of swaying steps. Therefore, it is possible that users can be informed of deviations from the average direction of movement by means of an acoustic signal and/or a vibration signal. This requires the average direction of movement of the user to be identified or detected first.
Even when deviations from the average direction of movement are included in the conversion (step c)) of the body position data into at least one acoustic signal and/or one vibration signal, a setting step (setting mode) preceding step c) can be performed.
Therefore, a setting step (setting mode) can be performed prior to the calibration step.
In the course of the setting step, it can first be defined at which degree of deviation (a1) from the average direction of movement an acoustic signal should be output. Furthermore, it is possible to define a degree of deviation 2 (a2) in the setting step, at which a maximum volume or an alarm tone in the form of an acoustic signal is output. Furthermore, it is possible to preset the system parameters such that a quickly responding and possibly loud or hard signal should be output or that a gently rising acoustic increase in one or both ears should be generated.
Also, performing the setting step, i.e. either selecting presets from a variety of available presets or making adjustments on the basis of real-time movement, can be done in the context of the degree of deviation as described above in the context of the degree of inclination.
As an alternative and/or in addition to an inclination value, the deviation from the average direction of movement can be played back acoustically. The option regarding the inclusion of the deviation from the average direction of movement can be formed to be switchable on and off.
In a further embodiment of the invention, it is possible, when determining the body position data in step a), to collect data regarding the step force, which can also be referred to as step strength or tread force. Step force or step strength or tread force is to be understood as the force with which the foot hits the surface when walking. The step force is detected by the inventive system as body tremor, for example. Preferably, the body position sensor unit for detecting this body tremor comprises at least one tremor sensor.
The data regarding the step force can be considered in step c), i.e. when converting the body position data into at least one acoustic signal and/or one vibration signal. In other words, the data regarding the step force can be included in the calculation of the acoustic signal and/or the vibration signal.
It is possible to output this step force data during the generation of the acoustic signal in amplified form as compared to the acoustic signals associated with body inclination data. This serves in particular to amplify acoustic signals with regard to the gait pattern. The user can thus obtain information about his/her gait pattern.
Furthermore, it is possible not to include or actively filter out the step force data when generating the acoustic signal. For users who only want to receive information about body sway, the additional outputting of an acoustic signal in connection with the step force can be disturbing. The user can better concentrate on body sway and compensation of body sway when the step force signal is filtered out.
In a further embodiment of the invention, in step a) data regarding the step length and/or the time duration of the ground contact of the two feet and/or the push-off height of the feet can be recorded. This data can be considered in step c), i.e. when converting the body position data into at least one acoustic signal and/or one vibration signal. In other words, the data mentioned can be included in the calculation of the acoustic signal and/or the vibration signal.
Furthermore, it is possible that the body position data determined in step a), in particular the determined inclination degree data, is converted into a visual image and sent to a display unit and/or stored in a database.
The task is further accomplished by a computer readable storage medium containing instructions that cause at least one processor to implement an inventive method according to one of the preceding embodiments when the instructions are executed by the processor.
This results in similar or identical advantages to those already described for the method described above.
In addition or as an alternative, reference is made to the schematic diagrams which describe (in more detail) the inventive system for walking and movement regulation aid, in particular the inventive system for posture and movement regulation, and/or the inventive method for walking and movement regulation aid, in particular the inventive method for posture and movement regulation for humans.
These are as follows:
In the following, the same reference numerals are used for identical or equivalent parts.
As shown in
In this case, the output unit is a headphone 31. Position sensors directly or indirectly attached to the body 10 or a body position sensor unit can send data regarding the position and/or inclination and/or rotation and/or posture as well as changes in position and/or inclination and/or rotation and/or posture to the arithmetic unit of the smartphone 20.
This data is converted in real time into at least one acoustic signal and/or one vibration signal. In the present case, the data is converted into stereo acoustic signals. The stereo acoustic signals 30 are output or perceived in the left ear 32 and/or in the right ear 33. The user can react to the stereo acoustic signal and change the body position. In the present case, the position sensors are integrated into the smartphone 20. Moreover, smartphone 20 may comprise an output unit 150 for vibration signals. This is indicated schematically by the emitted vibration signals 50.
As shown in
Since multiple vibration generators are attached to the carrying device 60, vibration signals can be emitted at different points of the body.
In
The goal of this inventive system/method is to give patients with balance disorders, during rehabilitation phases after accidents/operations or in the case of incorrect postures to be corrected additional, easily understandable feedback on their own posture or inclined position or body inclination and, in addition, to bring about a safe feeling and sense of stability in the user through the learning effect of the “new sense”. Moreover, the movement data can be made available to the user or doctors or researchers or trainers or physiotherapists.

As regards position and use on the body, it should be noted that a smartphone 20 optionally may also be attached either to the front of the body or to the back using a carrying device 70, as shown in
In connection with the sensors, in particular the position sensors, in particular the body position sensor unit, it should be noted that the inclination sensor data “front”, “back”, “left” and “right”, which are picked up by the smartphone 20, are picked up in degrees in real time via an application (app) and displayed visually. Illustration 100 shows that the body is slightly tilted forwards to the right. The application is preferably associated with a computing program stored in the arithmetic unit of the inventive system.

The setting step (setting mode) can be performed without attaching position sensors or without attaching a body position sensor unit. A first possibility for defining the active ranges is with the help of the control unit 120. In this process, first sensor values or first inclination values (n1) are defined. These are the smallest detected deviations from the 0° body position which must be at least exceeded in order to trigger the output of an acoustic signal.
Furthermore, second sensor values, in particular second inclination values (n2), must be specified. These inclination values n2 define the maximum degree of deviation from the 0° body position at which the maximum acoustic signal is output. This can be described as maximum in terms of pitch or duration.
The setting step in connection with the control unit 120 can be performed such that the user orients himself on the possible setting values and their visualized ranges in the control unit 120 and defines the threshold sensor values n1 and n2 by changing the values, namely by pressing the plus or minus keys. The additionally shown graph 101 visualizes the occurred movement data and serves to compare the fine adjustments.
A further embodiment of a setting step provides for the minimum and maximum values to be defined or for the first and second sensor values (n1, n2) to be defined by simply tapping on the control unit 120. To perform the setting step according to the second embodiment, it is first necessary to start the setting step or setting mode in the control unit 120. Subsequently, the user performs a real-time body inclination and defines the minimum and maximum values, i.e. the first and second sensor values, based on this. This may be performed as follows, for example:
First, a slight inclination to the first side (left or right) takes place. The first sensor value ( inclination value 1=n1) can be set by confirming the slight body inclination. In this context, the user does not have to hit a special key or field on the control unit 120, but can simply confirm this inclination value by tapping on the control panel 120. In this connection, the control unit 120 serves as a kind of feedback button.
Subsequently, a stronger body inclination is performed in the selected direction (left or right). By tapping on the control panel 120, the second sensor value ( inclination value 2=n2) is confirmed in turn.
In the presetting, the defined sensor values 1 and 2 for the other side of the body (left or right) can then be mirrored. On the remaining side, the same values n1 and n2 are set accordingly as for the previously defined values n1 and n2. It is also possible to set the sensor values 1 and 2 for the other body side separately from the first body side.
In one embodiment of the invention, it is possible for the setting step (setting mode) to be explained by a voice message, so that the individual steps, such as the initial slight inclination and the subsequent stronger inclination, can be carried out step by step on the basis of the voice message. The setting step according to the second embodiment may also be referred to as quick tap configuration. A therapist and/or a physician and/or a researcher can also use this second embodiment of the setting step. This can be done, for example, by a/the monitoring unit.
As shown in
As regards the sound or the acoustic signal as well as the inclination, the following should be explained: Depending on the therapy recommendation or one's own feeling, the beginning of the rising tone can be set at inclination level 1 and the maximum volume at inclination level 2 in each direction (see
This makes it possible for persons with a leaning basic posture to use the system/method/app. The at least one position sensor 20/40 can be attached quickly to the body 10, whereby it will probably never be installed 100% vertically by the user and in the present case does not have to be installed 100% vertically.
During the calibration process, the user can position himself as upright as he feels most comfortable. A mean value is determined, which is then defined as inclination grade 0.
The possibility of outputting a vibration signal is also shown. As regards the vibration as a warning signal in addition to acoustic signals in the application, the following should be explained: A maximum inclination value per inclination direction can be defined in the application as a warning indication or for therapeutic measures. If this is exceeded, a vibration signal is preferably output at the center of the body (
As regards the vibration and inclination with alternative or external sensors/devices, the following is explained: When using external BLUETOOTH short-range wireless communication technology standard vibration sensors, these are preferably arranged on the shoulders or assigned to the shoulders (see
As an alternative or in addition, it is possible to attach a vibration generator to a person's temple or to a spectacle frame.
As regards an analysis recording mode and storage in a database, the following is explained: If the analysis mode is selected (see
Optionally, the data can be made available to doctors or researchers or therapists or trainers via an online database (see
In principle, acoustic signals are played back 20 via headphones, which are connected to the smartphone via cable or BLUETOOTH short-range wireless communication technology standard, for example.
As regards the acoustic feedback obtained in this way, the following should be explained: Through a tone in the respective ear that increases with the degree of inclination, the user is informed acoustically in real time in which direction and to what extent he is currently inclined, by means of changing volume (left, right) and stereo sound character (front, back).
Depending on the personal sensation or therapy goal, the signal can generate a pressure resistance or a suction effect on the user.
As regards pressure resistance, the following should be explained: A low tone increases above the volume in the ear to which side the body is inclined. This means: inclination of the body to the right; the tone in the right ear becomes louder. The user often perceives this as increasing resistance (safety, stability) and increasing warning after a familiarization period.
As regards the suction effect, the following must be explained: A tone is played on the ear exactly opposite to the direction of inclination. The user may perceive this as a soft, pleasant correction after a period of familiarization, rather than a warning.
Optionally, the pressure and suction effect(s) can also be used for (external) vibration generators, as shown in
In connection with the pressure or suction effect, the following should be explained additionally: Depending on the sensation of the user or the therapy recommendation, the direction of inclination and the acoustic side of the tone (left ear, right ear) can also be reversed.
The inventive process steps a) to d) are shown schematically in
Body 10 has an inclined posture. The inclination or movement is represented by arrow N. The inclination values n1 and n2 can also be seen. These define the active range 102, as already explained in connection with
The body position data is sent as sensor data SD from the body position sensor unit 45 to the arithmetic unit 55. This can be done either via a radio link or via a cable. The sensor data is accepted in step 201. Subsequently, in step 202, the received sensor data or sensor values are compared with the previously defined sensor thresholds n1 and n2. In step 203, the sensor data SD, i.e. the body position data, is converted into control signals for generating an acoustic signal.
This signal is then sent to an audio module 35. This may comprise both an audio mixer unit 36 and a sound generation unit 37. Furthermore, it is possible that the sound generation unit 37 forms a separate unit from the audio mixer unit 36. The sensor data converted into control signals in step 203 is sent to the audio mixer unit. At the same time, a stereo audio signal can be generated in the sound generation unit 37. This is, for example, a continuous tone. Alternatively, the generation of tone sequences or a piece of music is possible. This stereo audio signal, in particular the audio data AD, can influence a left or right channel simultaneously using the audio mixer unit 36. The modified stereo signal can be transmitted to the left ear 32 and to the right ear 33, for example through headphones, or can be output there.
As shown in
According to the method shown in
It is also indicated that a second acoustic signal 132 is generated in connection with the deviation from the 0° position of the body forwards or backwards. In other words, a second acoustic signal 132, in particular a second stereo acoustic signal, is added in case of a forward or backward inclination. In the case of a forward or backward inclination, this second stereo acoustic signal 132 increasingly replaces the first stereo acoustic signal 131 (cross-fade), depending on the magnitude of the inclination and predefined settings. However, at the same time, the second acoustic signal 132 at the same time permanently conforms to the left-right ratio of the first acoustic signal 131.
As shown in connection with the left ear 32, the second acoustic signal 132 mixes with the first acoustic signal 131 depending on the degree of inclination. This is done up to the maximum drowning of the first acoustic signal 131.
In the example shown, the deviation AR is signaled by an acoustic signal in the left ear 32. Thus, deviations from a straight gait can also be detected and signaled. An inclination in the upper body of the user or the body 10 is not necessary here. A gait pattern that shows a sway is not generally associated with a leaning or inclined body. Rather, a swaying tendency can result from side steps or balancing steps. Due to the inclusion of deviation AR from the direction of movement BR during the conversion of the body position data into at least one acoustic signal, an advanced gait pattern improvement can be provided.
The conversion of the data regarding the deviation AR into an acoustic signal can be carried out as already described in connection with a body inclination to the left or right (or forwards or backwards). For example, if a threshold value, which can also be called a minimum value, is exceeded, an acoustic signal, in particular an increasing acoustic signal, can be output in the left ear to indicate a deviation from the direction of movement to the left. A deviation AR from the average direction of movement BR may be detected, for example, by determining a difference between the average direction of movement BR and the upper body alignment.
Furthermore, in
In
First, a body position sensor unit 45 is shown. This body position sensor unit 45 can comprise position sensors 40, which are formed separately from a mobile communication device. Furthermore, these can be sensors integrated into a smartphone 20. In particular, these can be position sensors, gyro sensors, gravitational sensors, acceleration sensors, tremor sensors, rotation sensors, magnetic sensors as well as mechanical sensors such as a cable sensor.
Furthermore, an external sensor unit 25 can be formed alternatively or additionally. This can be a camera, in particular a Kinect camera, i.e. a camera with depth sensors, or a balancing board. The body position data recorded by the body position sensor unit 45 are then sent as sensor data SD to the arithmetic unit 55. The arithmetic unit 55 can be part of a controller unit 56. Furthermore, the controller unit can comprise a storage 57. For example, a selection of system parameters can be stored in storage 57. The values n1 and n2 can also be stored there. It is also possible to store the selection of the sound method, logarithms, volume ranges, etc. in storage 57.
Furthermore, the controller unit 56 can have a communication unit 58. This communication unit 58 serves as an interface for data transmission. In this context, data can be exported as well as imported. The communication unit 58 can be a USB interface as well as a radio interface. Furthermore, with the help of the communication unit 58, Internet access can be provided via UMTS/LTE or WiFi. Furthermore, the communication unit 58 can comprise an interface to an online database.
Furthermore, an input and output module 130 can be formed. This can comprise a display unit 110 as well as a control unit 120. As already explained in connection with
An audio module 35 is also shown. This audio module 35 can comprise the previously described audio mixer unit 36 as well as the sound generation unit 37. Audio module 35 serves to generate audio data AD, i.e. acoustic signals which are sent to an output unit 140 for outputting an acoustic signal. In other words, sound generation unit 37 is an audio source for the generation of sound. This can be a tone generator or a synthesizer. An audio player can also act as a sound generation unit 37.
Furthermore, audio module 35 can have an audio signal input 39b as well as an audio signal output 39a. An audio signal input 39b is required if the audio module 35 has a sound generation unit 37. The audio signal input 39b can be designed as a socket for wired audio reception and as a wireless receiver, e.g. as a BLUETOOTH short-range wireless communication technology standard interface. The audio signal output 39a is the interface of the audio module 35, which sends the audio signal or the audio data AD to the output unit for outputting the acoustic signal 140. This can be a socket for wired audio output as well as a transmitter for wireless audio output, e.g. a BLUETOOTH short-range wireless communication technology standard interface.

This corresponds more or less to a remote function. As regards a remote function, the following is stated: Real-time remote access to the user is facilitated for therapists in order to be able to observe and analyze the processes on site during gait tests, but also by means of remote analysis, and optionally make modifications or adjustments to the app/method.
