Description

[0001] The invention relates to a mobile communication device designed to output a notification signal to notify a user of the mobile communication device in the form of a vibration according to a predetermined vibration pattern. The invention further relates to a method for operating a mobile communication device.

[0002] A mobile communication device can, for example, be a smartphone. Smartphones are known to have vibration motors to inform the user of an activity, such as an incoming call, a message, an input, or similar, in addition to or instead of an audible notification. For example, German patent DE 20 2013 012 697 U1 describes a mobile device with an output unit that may include a haptic module. This module can output signals that inform the user about events occurring on the mobile device. These signals can also include vibrations to indicate the occurrence of events.

[0003] Furthermore, DE 10 2016 225 644 A1 describes a method and a system for behavior-based authentication of a user. In this process, gross motor measurement data of a user is recorded by a mobile communication system, and the user is authenticated to this mobile communication system based on this measurement data.

[0004] Such a vibration pattern, which signals a notification to the user, can be configurable. For example, the user can select from several predefined vibration patterns or other ringtones in their mobile device's settings. The user can also select a desired intensity or volume. However, once selected, the type of notification signal is fixed. This signal may be too loud or too strong in some situations and thus be disruptive, while in other situations it may be too weak or have other characteristics that could cause the user to miss messages or incoming calls.

In: Procedia computer science, Vol. 19, 2013, pp. 902-907. - ISSN 1877-0509 describes the use of a smartphone to provide feedback based on the detected arm position during running. The smartphone's vibration intensity is set to a maximum value, and a standard vibration pattern is used as feedback. If the arm position deteriorates, the duration of the vibration is increased.

I: Methods, tools and user experience, pp. 397-406. - ISBN 978-3-030-22576-6 describes the investigation of the influence of various properties of tactile feedback, such as vibration intensity, frequency and interval between vibrations, on user satisfaction.

[0007] The object of the present invention is therefore to provide a mobile communication device and a method that make it possible to alert a user of the mobile communication device to notifications from the mobile communication device as effectively and appropriately as possible.

[0008] This problem is solved by a mobile communication device and a method with the features according to the respective independent patent claims. Advantageous embodiments of the invention are the subject of the dependent patent claims, the description, and the figures.

[0009] A mobile communication device according to the invention is designed to output a notification signal to notify a user of the mobile communication device in the form of a vibration according to a predetermined vibration pattern. Furthermore, the mobile communication device is designed to detect at least one movement characteristic of the rhythmic movement if the user carrying the mobile communication device performs such a movement, to define at least one vibration characteristic of the vibration pattern depending on this at least one movement characteristic, and, at least in the case of output of the notification signal while the user is performing the detected rhythmic movement, to output the notification signal in the form of a vibration according to the vibration pattern with the predetermined vibration characteristic.The temporal course of a vibration intensity or an envelope of the temporal course of the vibration intensity is periodic, wherein at least one of the following properties is assigned to the temporal course as the at least one vibration characteristic: a phase with respect to a reference time, a frequency or period, a characteristic of a rising edge from a minimum to the next maximum in time, a duration of a maximum, and a characteristic of a falling edge from a maximum to the next minimum in time.

[0010] The invention is based on the understanding that frequent activities such as walking, running, or cycling generally follow a consistent pattern or rhythm. In such cases, the mobile communication device carried, such as a smartphone in a trouser pocket, also moves relatively uniformly. If, by chance, the vibration pattern of the mobile communication device matches the user's movement, it may be poorly perceived or not perceived at all, at least when a notification signal is to be issued while the user is performing such a rhythmic movement. For example, a matching, increasing vibration when lifting the leg could be mistaken for, or even obscured by, potential friction from the trousers during this movement.In other words, the invention is based on the understanding that not only can a vibration signal that is too weak lead to it not being perceived by a user, but also that certain characteristics of such a signal, such as its being too uniform or similar to the current activity pattern, i.e., the rhythmic movement, for example, with regard to frequency and increase in intensity. Furthermore, the invention is based on the understanding that it is also possible to detect the rhythmic movements of a user carrying a mobile communication device. This can then advantageously be used to specify a suitable vibration characteristic of the vibration pattern depending on the at least one detected movement characteristic of the rhythmic movement.This advantageously allows for adjustment of the vibration pattern, so that it can be better perceived by the user even in the case of rhythmic movements. In particular, this advantageously prevents synchronization between the user's rhythmic movements and the vibration pattern. To avoid this synchronization, there are numerous adjustable vibration characteristics, such as frequency, phase, vibration duration, and so on, which will be explained in more detail later. This allows for particularly good situational adaptation, especially during sporting activities or rhythmic movements in general.

[0011] The mobile communication device is preferably a mobile phone, in particular a smartphone, but it can also be a wristband or wristwatch with communication capabilities, or even communication-enabled glasses, such as virtual reality glasses or augmented reality glasses, or similar devices. Furthermore, it is preferred that the notification signal is a signal to notify the user of an incoming call or a set alarm. Such notification signals are generally longer-lasting and end, for example, only after the caller hangs up, or the called party rejects or accepts the call, or, in the case of an alarm clock, when a predetermined time period has elapsed and / or the user performs an active action to end the alarm.Nevertheless, it is also conceivable that the notification signal informs the user about any other message received from the mobile communication device or about a message to be sent to the user by the device.

[0012] Preferably, a vibration pattern is understood to be a pattern that causes the mobile communication device to vibrate, then pause, then vibrate again, and so on. In other words, the individual vibration phases of the vibration pattern may be interrupted by periods of rest. Furthermore, a rhythmic movement is understood to be a movement that is performed repeatedly and is very similar to itself. Such movements include, for example, walking, running, skipping rope, cycling, and so on. Movements performed on exercise equipment such as a cross trainer or during aerobics can also constitute such rhythmic movements.The fact that, at least in the case of a notification signal being issued while the user is performing the detected rhythmic movement, the notification signal is issued in the form of a vibration with the predefined vibration characteristics, is to be understood as meaning that if the user is either not performing a rhythmic movement or if none is detected, then no vibration characteristics are specified based on the movement characteristics. Furthermore, it may be possible to specify a vibration characteristic based on the detected rhythmic movement and its movement characteristics, even if no notification signal is currently intended to be issued by the mobile communication device. For example, the mobile communication device may be designed to continuously define such a vibration characteristic based on the movement characteristics, perhaps at repeated time intervals.For example, if a call is received on the mobile communication device and a notification signal is to be emitted while the user is still performing the rhythmic movement, the mobile communication device can use its predefined vibration characteristics, adapted to the currently performed rhythmic movement, and emit the notification signal accordingly. Alternatively, it can be configured that the mobile communication device only determines a vibration characteristic based on the detected rhythmic movement and emits the notification signal when the notification signal is about to be emitted, for example, when an incoming call is being received.The first described case has the advantage that a faster output of the notification signal according to the specified vibration characteristics is possible, while the second case has the advantage that an analysis of the rhythmic movement and a suitable determination of the vibration characteristics can be dispensed with as long as no notification signal is to be output by the mobile communication device.

[0013] In an advantageous embodiment of the invention, the at least one vibration characteristic represents a property of the temporal profile of a vibration intensity or of the envelope of that temporal profile, and the movement characteristic represents a property of the temporal profile of an acceleration of a body region of the user. This is particularly advantageous because rhythmic movements are often characterized by the fact that, in particular, the acceleration of a body region of the user exhibits a repeating, periodic temporal profile. The acceleration of such a movement thus increases and decreases periodically, oscillating between a minimum and a maximum. The same applies to the temporal profile of the vibration intensity or the temporal profile of the envelope of this vibration intensity.This advantageously allows for the definition of corresponding characteristics, which can then be selected to be particularly well-suited, for example, complementary, or generally distinct from one another. It is especially advantageous to define the vibration characteristic in terms of the temporal evolution of the envelope of the vibration intensity, since, for example, when tuning frequencies, it is not the vibration frequency itself that is decisive, which is typically significantly higher than the typical movement frequencies of rhythmic movements anyway, but rather a frequency of the vibration pattern, which, as described above, can consist of a vibration phase and a rest phase that alternate regularly. Such a vibration pattern can thus be described particularly well by the aforementioned envelope.

[0014] According to the invention, the temporal profile of the vibration pattern, i.e., the vibration intensity or the envelope, is periodic, wherein at least one of the following properties is assigned to the temporal profile as the at least one vibration characteristic: a phase with respect to a reference time point, a frequency or period, a characteristic of a rising edge from a minimum to the next temporal maximum of the temporal profile, in particular a duration and / or slope and / or temporal slope change of the rising edge, a duration of a maximum, and a characteristic of a falling edge from a maximum to the next temporal minimum of the temporal profile, in particular a duration and / or a slope and / or a temporal slope change of the falling edge.This provides numerous advantageous vibration characteristics that can be adapted to maximize the distinguishability from rhythmic movements performed by the user. In particular, the edges of the vibration signal—that is, the rise and / or fall of the edge—can be specifically designed with regard to various characteristics depending on the detected rhythmic movement, thus enabling good differentiation. Not only can the duration of such an edge be adjusted, but also the shape of the time derivative of the signal, especially higher-order derivatives, such as the change in slope. For example, a non-linear slope of the rise or fall of the vibration signal can provide good contrast to a linear slope of the rise or fall of the rhythmic movement.their recorded acceleration profile and vice versa.

[0015] Corresponding properties can also be defined with regard to the motion characteristics. Accordingly, it represents a further highly advantageous embodiment of the invention if the mobile communication device is designed to assign at least one of the following motion characteristics to the detected rhythmic motion, in particular the temporal profile of the acceleration: a phase with respect to a reference time, a frequency or period, a duration and / or slope and / or change in slope of an edge rise from a minimum to the next maximum in the temporal profile, a duration of a maximum, and a duration and / or slope and / or change in slope of an edge fall from a maximum to the next minimum in the temporal profile.

[0016] In other words, the same characteristics suitable for characterizing the envelope of the vibration pattern can also be used to characterize the rhythmic movement of the user. Furthermore, it is particularly advantageous if corresponding characteristics differ from one another, or at least if one of the possible characteristics mentioned does.

[0017] For example, according to an advantageous embodiment of the invention, the mobile communication device is configured such that the at least one vibration characteristic is predetermined depending on the at least one movement characteristic such that the temporal profile of the vibration intensity or envelope and the temporal profile of the acceleration differ in at least one phase, in particular wherein the temporal phase difference is at least one-quarter of a period of the temporal profile of the vibration intensity or envelope and / or the temporal profile of the acceleration. According to this advantageous embodiment of the invention, the frequencies of the movement and the vibration pattern can also coincide, for example, as long as the respective temporal profiles are sufficiently phase-shifted relative to each other. The phases refer to the same reference point in time.For example, the beginning of a maximum in the temporal progression of the vibration pattern's envelope can serve as such a point of reference. In other words, the maxima and / or minima of the respective temporal progressions of the vibration pattern and the rhythmic movement should be shifted relative to each other and, if possible, should not coincide. A temporal shift of half a period, defined, for example, by the interval between two immediately successive maxima or minima, is particularly advantageous, as this allows for maximum contrast between the rhythmic movement and the vibration pattern. However, even a temporal shift of, for example, a quarter of a period is sufficient and significantly increases the probability that the generated vibration signal will be perceived by the user.

[0018] The phase shift is particularly advantageous when, as described, the frequencies of the rhythmic movement and the vibration pattern coincide. Otherwise, the frequencies differ, which is also advantageous, as this too increases the likelihood that the vibration signal will be perceived by the user. Accordingly, it represents a further advantageous embodiment of the invention if the mobile communication device is configured such that the at least one vibration characteristic is predetermined as a function of the at least one movement characteristic such that the temporal profile of the vibration intensity or envelope and the temporal profile of the acceleration differ at least in one frequency or period. The frequency is defined, as usual, as the inverse of the period.Different frequencies or periods automatically lead to the situation that, at most, the movement and the vibration do not overlap, at least in one period of time, but are also offset from each other.

[0019] In a further advantageous embodiment of the invention, a frequency associated with the temporal profile of the acceleration is many times greater than a frequency associated with the temporal profile of the vibration intensity or the envelope. In other words, when emitting the notification signal, the mobile communication device vibrates several times during a period of the user's rhythmic movement; that is, the vibration signal exhibits several vibration phases within this period. Due to the different frequencies, the vibration signal can be clearly perceived by the user, while the higher vibration frequency of the vibration phases, due to the more frequent vibrations, further increases the probability of perception.Furthermore, the multiple can refer to an integer multiple or to a non-integer multiple, for example a non-integer rational multiple or an irrational multiple.

[0020] In a further advantageous embodiment of the invention, the mobile communication device is configured such that the at least one vibration characteristic is predetermined depending on the at least one movement characteristic, such that the temporal profile of the vibration intensity or the envelope and the temporal profile of the acceleration differ with respect to the duration of a rising edge and / or maximum and / or falling edge. A rising edge, as defined above, represents the increase between a minimum and the next maximum in time. Correspondingly, a falling edge represents the time interval between the maximum and the subsequent minimum. With regard to the vibration characteristic or vibration pattern, this can also exhibit a temporally extended maximum. Depending on the sporting activity, this can also apply to rhythmic movement.These characteristics, both in terms of the vibration pattern and the user's movement sequence, advantageously provide additional or further possibilities to enhance the distinguishability of the vibration pattern from the movement sequence. For example, the vibration pattern can be adjusted so that the vibration rises to its maximum much faster and remains there for a significantly longer period than is the case with rhythmic movement. In this case, the frequencies or phases of these temporal progressions do not necessarily have to differ, as the design of these transition times also provides the possibility of clearly distinguishing the vibration pattern for the user.However, as mentioned above, not only the durations of such flanks can differ, but also their slopes and / or changes in slope.

[0021] In a further advantageous embodiment of the invention, the mobile communication device includes a sensor unit for detecting the motion characteristics. Such a sensor unit can, in particular, be designed as an IMU (inertial measurement unit). Such an inertial measurement unit typically comprises several individual sensors, such as a gyroscopic sensor, also called a gyroscope, and / or an accelerometer. Alternatively or additionally, the mobile communication device can also include a camera and / or a proximity sensor and / or an air pressure sensor and / or a magnetic sensor or similar devices for detecting the motion characteristics.The recording of rhythmic movement, and in particular the aforementioned characteristic, will not be discussed further below, as the recording of such movement characteristics is already known from various fitness trackers. These use activity recognition to record sporting activities such as running, cycling, step counting, and so on. It is also conceivable that the mobile communication device could record the rhythmic movement by being communicatively coupled with another device that possesses such sensors. In other words, the mobile communication device could also obtain information about a current rhythmic movement and its movement characteristics from another such device and not directly record it itself. However, it is preferable for the mobile communication device itself to be used for sensing, i.e.,The device is designed for sensory detection of rhythmic movement and its characteristics using suitable sensors, as this offers the significant advantage of capturing movement precisely at the location of the mobile communication device. This allows the device to precisely match the vibration characteristics to the rhythmic movement, thus achieving maximum differentiation. For example, if the mobile communication device is carried in the user's trouser pocket, the movement of their leg, and perhaps their arm, will also be detected. Conversely, if the user wears the device as a wristwatch, the movement of their wrist and arm will be detected, but not their leg, at least not directly.This allows the mobile communication device to adapt its vibration characteristics particularly well to the rhythmic movement currently being performed by the relevant part of the body on which the mobile communication device is located at that moment.

[0022] Furthermore, the invention also relates to a method for operating a mobile communication device, wherein the mobile communication device outputs a notification signal to notify a user of the mobile communication device in the form of a vibration according to a predetermined vibration pattern. In this context, the mobile communication device detects at least one movement characteristic of the rhythmic movement if the user carrying the mobile communication device performs such a movement.Furthermore, the mobile communication device specifies at least one vibration characteristic of the vibration pattern depending on the at least one movement characteristic, and at least in the case of an output of the notification signal while the user performs the detected rhythmic movement, the mobile communication device outputs the notification signal in the form of the vibration according to the vibration pattern with the specified vibration characteristic.The temporal course of a vibration intensity or an envelope of the temporal course of the vibration intensity is periodic, wherein at least one of the following properties is assigned to the temporal course as the at least one vibration characteristic: a phase with respect to a reference time, a frequency or period, a characteristic of a rising edge from a minimum to the next maximum in time, a duration of a maximum, and a characteristic of a falling edge from a maximum to the next minimum in time.

[0023] The advantages mentioned for the mobile communication device and its configurations apply equally to the method according to the invention.

[0024] The invention also includes further developments of the method according to the invention, which have features already described in connection with the further developments of the mobile communication device according to the invention. For this reason, the corresponding further developments of the method according to the invention are not described again here.

[0025] The invention also includes the control device for the mobile communication device. The control device can comprise a data processing device or a processor unit configured to carry out an embodiment of the method according to the invention. For this purpose, the processor unit can comprise at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). Furthermore, the processor unit can comprise program code configured to carry out the embodiment of the method according to the invention when executed by the processor unit. The program code can be stored in a data memory of the processor unit.

[0026] The invention also includes combinations of the features of the described embodiments. The invention therefore also includes realizations that each exhibit a combination of the features of several of the described embodiments, provided that the embodiments have not been described as mutually exclusive.

[0027] The following are exemplary embodiments of the invention described. This is illustrated by: Fig. 1 a schematic representation of a mobile communication device worn by a user while performing a rhythmic movement according to an embodiment of the invention; and Fig. 2 a schematic representation of the temporal course of the rhythmic movement and the vibration pattern according to an embodiment of the invention.

[0028] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention, which can be considered independently of one another and each further develops the invention independently. Therefore, the disclosure is intended to include combinations of features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0029] In the figures, identical reference symbols denote functionally equivalent elements.

[0030] Fig. Figure 1 shows a schematic representation of a mobile communication device 10 according to an embodiment of the invention. In this example, the mobile communication device 10 is worn by a user 12 who performs a rhythmic movement, for example, by walking. The mobile communication device 10 is also carried in a trouser pocket of the user 12 in this example, which is why the mobile communication device 10, as well as its components 12 and 14, are shown only with dashed lines. The mobile communication device 10 has a detection unit 14, which is designed to detect the rhythmic movement of the user 12 and, in particular, to determine at least one movement characteristic based on the detected measurement data, as will be explained in more detail later.For this purpose, the detection unit 14 can have one or more sensors, such as an inertial measurement unit, and / or a camera, a proximity sensor, or an air pressure sensor. Furthermore, the mobile communication device 10 has a control and evaluation unit 16 with memory. This memory can contain various vibration patterns, which can be parameterized so that their vibration characteristics, or at least one of them, can be adjusted. Such a vibration pattern defines the temporal progression of a vibration that can be output as a notification signal to inform a user, for example, of an incoming call.The mobile communication device 10, in particular its control and evaluation unit 16, is advantageously designed to select or modify a vibration characteristic based on the measurement data acquired by the detection device 14, such that, in the event of a vibration signal being emitted during the execution of the rhythmic movement by the user 12, the best possible contrast is provided to this harmonic movement of the user 12. The possibilities for adjusting such a vibration signal so that it can be distinguished as clearly as possible from this rhythmic movement are now described below. Fig. 2 explained in more detail.

[0031] Fig. Figure 2 shows, firstly in the upper representation, the temporal progression 18 of the rhythmic movement of the user 12, in particular the temporal progression 18 of the acceleration a of the body area 20 (compare Fig. 1), to which the detection device 14 for recording this rhythmic movement is also assigned. This movement, or rather this temporal progression 18, is periodic, where T0 denotes the period length of this temporal progression 18. In this example, it represents the time interval between two maxima M of this temporal progression 18. The minima are accordingly denoted by m.

[0032] Furthermore, in Fig. Figure 2 below shows the temporal profile 22 of the envelope E of the vibration signal 24 and its intensity profile 24. This temporal profile 22 of the envelope E exhibits vibration phases 26, during which the mobile communication device 10 performs a vibration, and rest phases 28 between the vibration phases 26, during which the mobile communication device 10 does not perform a vibration. In this example, these rest phases also define the minima of the signal profile 22 of the envelope E. These rest phases 28 are not necessarily required. The Fig. The vibration pattern 22 shown represents the vibration pattern 22 according to which the notification signal is issued by the mobile communication device 10 when the user 12 performs the function described above. Fig. The device 10 performs the rhythmic movement described above. This vibration signal 22 differs in many respects from the rhythmic movement and its temporal progression 18, which significantly increases the probability that the user 12 will perceive this vibration signal 22. The mobile communication device 10 can modify the vibration characteristics so that they differ as much as possible from the movement signal 18, as follows. Firstly, this vibration signal 22 is also assigned a period length T1, which extends from the middle of one maximum to the middle of the next maximum. This differs from the period length T0 of the movement signal 18 and, in this example, is specifically half as long. This means that the vibration frequency is twice as high as the movement frequency of the movement signal 18.These two signals 18 and 22, that is, their respective defined time profiles 18 and 22, also exhibit a phase shift Δφ relative to each other. In this example, the phase is defined with respect to the beginning of a minimum m, 28 of the respective signals 18 and 22. This results in the respective maxima M and M' also being phase-shifted relative to each other and thus not synchronous.

[0033] Furthermore, a duration D1 of a rising edge of the vibration signal 22, as well as a duration D2 of a vibration maximum M', and a corresponding duration D3 of the falling edge, can also be determined, as in Fig.The vibration signal 22 is defined as shown in Figure 2. Corresponding quantities D1' and D3' can also be defined for the rhythmic movement. In this example, the duration of the maximum M of the rhythmic movement is equal to 0 or at least approximately 0, so it is not explicitly shown. These durations can also be chosen differently by correspondingly adjusting the vibration signal 22. In this example, the rise time D1' of the vibration signal 22 is significantly shorter than that of the rhythmic movement. Conversely, the duration D2 of the maximum of the vibration signal 22 is significantly longer than that of the rhythmic movement. In addition to these rise times D1 and D3, other rise characteristics, in particular a slope and / or change in slope, can also be chosen depending on the rhythmic movement to allow for better differentiation.

[0034] In total, numerous characteristics are thus provided, such as period T0, T1, phase shift Δφ, the durations D1, D2, D3, D1', D3' of corresponding signal sections, etc., which can advantageously be used to provide a vibration signal with the best possible contrast to the harmonic movement of the user 12.

[0035] Overall, the examples show how the invention can provide an adaptive vibration pattern which, through situation-dependent, adaptive vibration behavior, makes it possible to increase the user's attention to this haptic notification and, if necessary, prevent the notification from being missed.
