Description

[0001] This invention relates to a mobile phone device (such as a smartphone, tablet, etc.) and to a method for blocking calls from said mobile device; particularly unintentional calls, such as unintentional calls made by a user due to accidental movement or gestures.

[0002] As is well known, both traditional and VoIP (Voice Over IP) telephone networks are a common and widely used communication method, meaning they are available worldwide and easily accessible through various means, such as public landlines, mobile devices, and shared lines in hotels. This makes telephone calls a faster and most readily accessible medium for communicating and exchanging information during remote conversations between two people.

[0003] Throughout the day, many people send and / or receive important messages by phone, such as the evolution of an illness or the death of a loved one, the end of a personal relationship, the progress of business negotiations, and the trend of a company or stock.

[0004] Important messages sent or received during a phone call can cause a change in one of the callers' emotions. Therefore, it is not uncommon for one of the callers to be in a changed emotional state (such as anger, frustration, happiness, or excitement) when the call ends.

[0005] Especially when a person is in a changed emotional state, he / she may unintentionally make unexpected or uncontrollable actions or gestures; for example, this is the case when a phone call starts unexpectedly.

[0006] Under normal circumstances, it is also possible for owners of mobile phones equipped with touchscreens (especially those commonly referred to as smartphones) to unintentionally make a new call immediately after ending a previous call. This is more likely to happen with such mobile phones or devices because their operation can be controlled via the touchscreen by simply tapping it or by touching controls that are typically composed of icons.

[0007] In practice, it is common for users to accidentally touch icons or other controls when placing their mobile phone on a flat surface (table or desk) or putting it in their pocket or bag after ending a call, thus accidentally making a call.

[0008] The purpose of this invention is to solve this problem and others by providing a method for preventing the activation of unwanted telephone calls from a mobile phone device.

[0009] Another object of the present invention is to provide a mobile phone device capable of implementing this method, thereby temporarily blocking any other calls that occur after a telephone call has ended.

[0010] The basic idea of ​​this invention is to temporarily prohibit or prevent mobile phone devices (such as smartphones, tablets, etc.) from making calls based on a signal generated when a user's telephone call ends.

[0011] The signal represents a quantity related to or associated with the telephone device itself or with the surrounding environment (e.g., background noise), or with an external device (e.g., headset, microphone, etc.) that communicates with the mobile phone device.

[0012] More specifically, but not limited thereto, the signal indicates the operating state of the mobile phone device: for example, in the case of a signal provided by an accelerometer and / or gyroscope, particularly contained in the telephone device, the signal may indicate the spatial orientation (e.g., vertical, horizontal, or tilted) of the device itself at the end of a telephone call.

[0013] Signals provided by accelerometers and / or gyroscopes (preferably three-dimensional accelerometers and / or gyroscopes) can also indicate any acceleration experienced by the mobile phone device, such as acceleration that may occur in the event of a fall, vibration, etc.

[0014] It must also be pointed out, as will become apparent below, that the possibility of temporarily barring a call can be based on signals provided by other sensors (such as magnetometers, proximity sensors, temperature sensors, etc.).

[0015] It should also be added that, according to the present invention, one or more signals can be used in combination to activate the temporary call blocking function; this means that a combination of signals provided by an accelerometer and / or gyroscope and / or magnetometer and / or proximity sensor and / or temperature sensor or even through an earpiece or microphone outside the mobile phone device can be used.

[0016] All of the aforementioned sensors are typically included in smartphone-type mobile phone devices; therefore, the method of the present invention can be implemented in commercially available products, i.e., used on a large scale for a large number of users.

[0017] Typically, if the spatial orientation of a mobile phone device remains substantially the same for a predetermined period of time (e.g., ten seconds or more) after a call ends, it can be assumed that the phone was not used by the user and that the icon or control for starting another call after the call has just ended was accidentally touched, thus assuming that the new call was unintentional.

[0018] In this case, the method of the present invention can prevent unwanted calls when applied to a mobile device.

[0019] It should be noted that this effect is temporary, meaning it lasts for a preset time interval, which preferably includes the period between the end of a call and the start of the locked or dimmed state of the telephone device, also commonly referred to as "standby".

[0020] The latter state occurs after the phone has been inactive for a certain period of time, usually about one minute (but this can be changed by the user). After this state, the display dims and calls cannot be made (except for emergency calls). To unlock the phone in this state, a code or a user identification procedure (such as fingerprint or iris scanning) must be performed.

[0021] The method according to the invention operates in a phase prior to the “standby” phase by blocking accidental or otherwise unintended calls; the method begins at the end of a telephone call, after an action, gesture, or situation that in some way relates to or involves the user.

[0022] Therefore, for example, in addition to the aforementioned signals that indicate the spatial orientation of the device, temporary call blocking can also be achieved by utilizing interactive signals that indicate the user does not want to make new calls (i.e., signals associated with or generated by one or more actions performed by the user after a call ends).

[0023] These are interactions that can cause changes in the operating state of a mobile phone device; for example, signals indicating the location and / or orientation of the headset (used for calling) after a call has ended; or signals indicating the path followed by the mobile phone device after a call has ended, wherein the interaction signals allow understanding of what is happening on the mobile phone device after a phone call.

[0024] For example, let's consider a situation where the phone is held in the user's hand, but the phone moves because the user's hand is trembling. This trembling can be sensed by an accelerometer or a gyroscope, which will change the phone's operating state and send corresponding signals.

[0025] In this way, in addition to establishing spatial orientation of the mobile phone device, the detection of a given type of interaction between the mobile phone device and the user can prevent (undesired) calls from being made after the call has ended.

[0026] The features of the invention will be set forth in more detail in the appended claims.

[0027] These features and further advantages of the invention will become more apparent from the following description of preferred, though non-limiting, embodiments of the invention as shown in the accompanying drawings, which are provided only by way of non-limiting example, wherein:

[0028] - Figure 1A communication system including a mobile phone device according to the present invention is shown;

[0029] - Figure 2 It shows the representation Figure 1 A block diagram of some parts of a mobile phone device;

[0030] - Figure 3 A flowchart illustrating a stage of an embodiment of the method according to the present invention is shown.

[0031] Before proceeding further, it should be noted that any reference to "one embodiment" in this specification indicates that a particular configuration, structure, or feature is considered to be included in at least one embodiment of the invention. Therefore, expressions such as "in one embodiment" that may appear in different parts of this specification are not necessarily related to the same embodiment, such that the various configurations, structures, or features described herein may be combined in one or more embodiments that are deemed suitable.

[0032] Finally, it should be noted that the alphanumeric references used below are intended to facilitate the understanding of the invention, and do not limit the scope and extent of protection of the claimed embodiments.

[0033] Taking this into account, it can be explained that, with reference Figure 1 and Figure 2 The following describes a communication system S comprising at least one mobile phone device 1 (e.g., smartphone, tablet computer, etc.) manufactured according to the present invention.

[0034] In addition, mobile phone device 1 includes the following parts or components:

[0035] - Processing device 11 (e.g., CPU, CPLD, FPGA, microcontroller, etc.) is used to process data and execute command and instruction programs;

[0036] - Input and / or output device 12 (e.g., USB, Firewire, RS232) (or WiFi controller, etc.), which can collect input signals and / or transmit output signals;

[0037] - Transceiver 13, which is adapted to send and receive telephone calls via a communication network (preferably GSM, GPRS, EDGE, UMTS, LTE, 5G, WiFi network, etc.) for example via a switching network or VoIP service;

[0038] - Interface device 14 (e.g., touch screen, alphanumeric keypad including call hang-up button, microphone / speaker system, etc.) that allows interaction with the user of the mobile phone device 1;

[0039] - Memory device 15 (e.g., RAM, ROM, flash memory, etc.) capable of storing data and / or instruction sets that implement and allow stages of the method for prohibiting unwanted calls according to the present invention;

[0040] - Communication bus 19, which is used to exchange data and information between at least two of the above-described devices or elements 11-15.

[0041] Processing device 11 is preferably configured to perform the following steps:

[0042] - The telephone call is terminated according to a command sent and / or received to the mobile phone device 1. Termination of the telephone call can be accomplished in several ways: for example, by activating one of the user-initiated interface devices 14 (typically the user touches a specific icon displayed on the touchscreen, or presses a button via...). The button of a wired or wireless headset that communicates with the mobile phone device 1 via the network, or the receiving of a call hang-up signal via the transceiver 13, for example, when the caller hangs up, or when the signal is lost, or for other reasons.

[0043] - The input device 12 acquires a signal representing at least one quantity or associated with one or more of the following options:

[0044] i) The environment surrounding the mobile phone device 1 (e.g., background noise, vibration, temperature, etc.);

[0045] ii) External devices (e.g., headsets, microphones, etc.) that communicate with mobile phone device 1 (or Wi-Fi connector);

[0046] iii) The operating state of the mobile phone device 1 (e.g., the spatial orientation of the mobile phone device 1 after a telephone call ends).

[0047] Preferably, the operating signal is obtained by acquiring and processing data generated by the sensor 17 in combination with each other, or even only partially combined; such sensor 17 includes an accelerometer (preferably a three-dimensional type accelerometer, etc.) and / or a gyroscope and / or a magnetometer and / or a proximity sensor and / or a temperature sensor, all of which are typically included in the latest generation of telephone devices (smartphones, tablets, etc.) such as mobile phone device 1.

[0048] The data provided by sensor 17 allows the following:

[0049] - The spatial orientation of the telephone device 1 is estimated based on factors such as the direction of gravity or the geomagnetic field, the proximity of the device to the user's face, or by determining whether the device is stationary (e.g., placed on a table);

[0050] - Determine the duration of the time interval, wherein the directional signal represents a substantially stable orientation of the mobile phone device 1. For example, this can be accomplished by calculating the time during which the first derivative of the spatial directional signal with respect to time remains below a threshold, preferably equal to at least 10 / 60 of a degree per second;

[0051] - Within a preset time interval, calls made by mobile phone device 1 are blocked based on the operation signal; for example, this can be accomplished by calculating the time during which the first derivative of the time relative to the spatial orientation signal remains below a preset threshold, preferably equal to at least 10 / 60 of a second, and if the duration of the interval exceeds the threshold (preferably equal to at least 10 seconds), activation of any telephone call is blocked.

[0052] During this phase, telephone device 1 temporarily denies access to functions that allow calls, or alternatively, if the spatial orientation signal changes significantly relative to an idle location, the telephone device may restore the call-enabled state, or it may request an unlock code to make a new call or perform other actions (such as sending a text or voice message).

[0053] This can prevent unwanted calls from being made immediately after a call has been terminated.

[0054] However, it must be pointed out that when a telephone device is in this temporary call blocking phase, any incoming calls will still be enabled as if the telephone device were not in the temporary blocking phase.

[0055] It should be noted that the functions performed by the processing device 11 are preferably associated with or implemented through an application (so-called "App"), which is stored in the memory device 15 or associated with the telephone device 1 in any way; such an application can preferably be activated by a command, which may also be a voice command and / or a command executed by an icon displayed on the touch interface device 14.

[0056] From a functional perspective, in Figure 3 The diagram shown illustrates the above-mentioned operational stages.

[0057] As can be seen, when the mobile phone device 1 is in operation, the processing device 11 preferably executes a set of instructions contained in the memory device 15, which implements a phase of the method for blocking unwanted calls according to the present invention.

[0058] The method basically includes the following stages:

[0059] -Call termination phase P1, wherein the user terminates the telephone call by sending and / or receiving a command to the mobile device 1;

[0060] - Acquisition phase P2, wherein at least one operation signal generated at the end of the first call is acquired via input device 12;

[0061] - Temporary blocking phase P4, wherein the processing device 11 blocks calls made through the mobile phone device 1 within a preset time interval based on the operation status signal.

[0062] Therefore, unwanted calls can be avoided within a preset time after a call ends. This preset time can start two or three seconds after the call ends, which is usually the time it takes to put the phone on a table, put it in a pocket, or remove the headset, or the preset time can be longer.

[0063] In a preferred embodiment, the operating signal includes an orientation signal indicating the spatial orientation (i.e., vertical, horizontal, or tilted) of the mobile phone device 1.

[0064] For example, in one possible embodiment of the invention, an analysis phase P3 is also envisioned, in which the processing device 11 (at the start or end of the acquisition phase P2) determines the duration of a time interval during which spatial orientation signals indicate a generally stable operating state of the mobile phone device 1 or interactive signals indicate the user's intention not to make new calls.

[0065] For example, if the orientation data is generated by the accelerometer and / or gyroscope 17 or by the magnetometer, this can be accomplished by calculating the first derivative with respect to the orientation signal over time.

[0066] Then, during phase P4, if the (average or punctual) value of this derivative is greater than or less than a given threshold, calls via mobile phone device 1 will preferably be blocked for a period of at least 5-10 seconds.

[0067] This makes it possible to avoid most unwanted calls after the call ends, as the user may have inadvertently touched the mobile device's touchscreen after the call, for example, when putting the mobile device 1 into a pocket or bag, or due to accidental gestures or negligence.

[0068] It must also be noted that the above-described operation phase of the method of the present invention is performed during a time interval prior to the moment when the telephone device 1 enters an idle or suspended state (commonly referred to as "standby"); the suspended state occurs after a preset time (which is usually one minute, but may vary depending on the mobile phone model or the user's choice), and the activation of the suspended state means that the touchscreen dims and causes all functions to be locked (except for a few functions, such as emergency calls), so that in order to restore these functions, the device must be unlocked by entering an access code or by performing user fingerprint, iris or facial recognition.

[0069] The invention operates before the "standby" phase, when all normal functions of the telephone device 1 are accessible through its interface, which is a touchscreen in a smartphone-type telephone.

[0070] According to the above, the operation signals collected by the input device 12 during the acquisition phase P2 include interactive signals indicating the user's reaction after the telephone call ends. This can cause a change in the operating state of the mobile phone device 1, so that during the temporary prohibition phase, for example, if no prohibition is set during the prohibition phase P4 based on the directional signal, unintentional calls are prevented based on the interactive signals.

[0071] It must be emphasized that, compared to, Figure 3 The sequential evaluation shown can also evaluate directional and interactive signals in parallel.

[0072] In other words, during the temporary blocking phase P4, the processing device 11 evaluates whether the call should be blocked based on the interaction signal, and if the evaluation result is positive, the processing device 11 will temporarily block the call made through the mobile phone device 1.

[0073] Interactive signals indicating the user's intention not to make new calls may include, for example, a (proximity) signal generated by a proximity sensor (preferably an infrared-sensitive type of proximity sensor) or other signals (some of which will be described below), which may be included in the mobile phone device 1, and whose signals indicate the distance between a human body (e.g., the user's face) and the front of the mobile phone device 1.

[0074] This reduces the risk of unwanted calls being made immediately after a call is terminated.

[0075] In a preferred embodiment of the invention, the mobile phone device 1 includes an accelerometer and / or gyroscope sensor device 17 (such as a sensor belonging to the ICM-206XX or MPU-6XXX series manufactured by TDK Inven Sense), wherein the accelerometer and / or gyroscope device 17 is configured to generate an orientation signal representing the spatial orientation of the device 1 by, for example, determining the direction of the Earth's gravity (using an accelerometer) and / or by integrating the angular velocity data from the gyroscope device 17 over time and adding them to data about the initial orientation (during the acquisition phase P2).

[0076] As an alternative to or in combination with the accelerometer and / or gyroscope device 17, the mobile phone device 1 may also include a magnetometer that generates an orientation signal representing the orientation of the mobile phone device 1 relative to the Earth's magnetic field.

[0077] More specifically, if the phone has been placed on a flat surface for a certain period of time since the end of the call, or has been put in a pocket, or has been held in the user's hand for a certain period of time, the processing device 11 can be configured to obtain orientation data that defines the spatial orientation of the device 1 (during the analysis phase P3).

[0078] The accelerometer and / or gyroscope device 17 is also preferably used in conjunction with a proximity sensor and / or a temperature sensor to generate an interactive signal that allows for understanding of the user’s reaction at the end of the call, for example by analyzing a first portion of the signal generated by the accelerometer and / or gyroscope device 17 over a predefined time interval starting from the moment the call ends, and using subsequent portions of the signal to determine the spatial orientation of the mobile phone device 1.

[0079] In other words, the accelerometer and / or gyroscope device 17 generates a signal (preferably a digital signal) representing the spatial orientation of the mobile phone device 1 and comprising a first and a second portion that are sequentially connected in time.

[0080] Processing device 11 is configured to (during acquisition phase P2) generate (user) interaction signals based on the first portion (e.g., by copying and / or downsampling and / or filtering, etc.); and generate directional signals based on the second portion (e.g., by copying and / or downsampling and / or filtering, etc.). This allows processing device 11 to assess the situation regarding the user (during temporary inactivation phase P4); for example, if the hand of the person holding phone 1 trembles after hanging up the phone and before placing it on a flat surface, or if the phone is subjected to any impact or collision (due to a drop, accidental movement, etc.).

[0081] In reality, a user may experience trembling after ending a call (due to physical discomfort, a change in emotional state, or any other reason), or he / she may drop the telephone device 1 or bump it against another object (whether accidentally or not); in such cases, it is appropriate to (temporarily) disable communication to avoid potentially inadvertently calling any number in the phone book.

[0082] In this respect, it must be pointed out that such jitter can be detected by analyzing the frequency of the signals generated by the acceleration and / or gyroscope device 17 or by the magnetometer.

[0083] In addition to the above, the accelerometer and / or gyroscope device 17, as well as any other sensors in use (such as a magnetometer), may allow the detection of other situations of interest to the purposes of this invention.

[0084] For example, when the call ends while the user is walking or running; in this case, it is best to prevent the call from being made before the phone automatically switches to standby mode, as the user is more likely to make the call unintentionally due to accidental touches or contact with the screen (such as when he / she is trying to put the device 1 into his / her pocket or is making other gestures).

[0085] According to the invention, when a user is walking or running, the jolts caused by his / her footsteps are sensed by the accelerometer / gyroscope sensor 17, and a shutdown procedure (routine) is initiated; in this respect, it should be noted that the energy present in the frequency spectrum of the interactive signal in the range of 0.5Hz to 3.5Hz is typical of walking or running rhythms.

[0086] Therefore, the signal provided by the acceleration and / or gyroscope device 17 allows the processing device 11 to detect one or more of the above situations, enabling it to block unwanted calls after the call ends.

[0087] As an alternative to or other than the above, the communication system S may include one or more earphones 2 (preferably a pair), which are preferably connected via... The network or other means communicates signals with the mobile phone device 1 via cable.

[0088] Each of the earphones 2 includes a second acceleration and / or gyroscope device 21 configured to generate a second acceleration and / or gyroscope signal representing the acceleration and / or rotation and / or motion experienced by each earphone; the signal is at least partially transmitted to the mobile device 1: for this purpose, the second acceleration and / or gyroscope device 21 is preferably of a similar type to those devices 17 of the mobile device 1.

[0089] More specifically, the processing device 11 may be configured to detect some of the aforementioned situations (e.g., a user walking) by using a second signal generated by the second acceleration and / or gyroscope device 21 as an interaction signal instead of (or in combination with) the signal generated by the acceleration and / or gyroscope device 17 of the telephone device 1.

[0090] In this case, the interactive signal indicating the user's intention not to make a new call includes the second acceleration and / or gyroscope signal, and the processing device 11 can be configured to perform the following steps:

[0091] - Based on the interaction signal, (during the acquisition phase P2) it was detected that the earphone 2 had been removed from the user's ear (by the user of device 1) after the call ended;

[0092] - If the headset 2 has been removed, then (during the temporary prohibition phase P4) calls are prohibited through the mobile device 1; this means that removing the headset is a necessary and sufficient condition for generating the prohibition data.

[0093] In particular, if both earphones 2 are equipped with corresponding acceleration and / or gyroscope devices 21 and the interaction signal includes two signals generated by the acceleration and / or gyroscope devices, the processing device 11 can be configured to detect (during the acquisition phase P2) that the two earphones 2 have been removed (by the user of the device 1) in a synchronous manner, i.e., the two earphones are subjected to rotation in opposite directions, and preferably also to rotation and / or acceleration of similar intensity.

[0094] If the processing device 11 detects (by using spatial orientation signals) that the mobile phone device 1 has been placed in a pocket or on a table and / or (by using interaction signals) that the headset has been removed, this allows calls to be blocked via the mobile device 1 for a period of time after the call has ended; in fact, in this case, the user clearly has no intention of making a new call. Therefore, unwanted calls can be avoided after the previous call has ended.

[0095] As an alternative to or in combination with the second accelerometer and / or gyroscope device 21, each earpiece 2 may include a proximity sensor (preferably an infrared-sensitive type) configured to generate a proximity signal indicating whether the earpiece is on the user's ear. In this variant, the interaction signal includes the proximity signal, and the processing device 11 is configured to (during acquisition phase P2) detect the removal of at least one of the earpieces 2 based on the proximity signal. This avoids unwanted calls after the call is terminated and at least one earpiece 2 is removed.

[0096] As an alternative to or in combination with a proximity sensor, each earphone 2 may include a pressure sensor (preferably a piezoelectric type) configured to generate a pressure signal indicating whether the earphone 2 is coupled to the user's ear canal; in practice, the pressure sensor may be coupled to a contact portion of each earphone (i.e., the portion of the earphone 2 that deforms when the earphone physically contacts the user's ear canal); this portion may preferably be made of rubber (preferably silicone rubber) and may have a shape similar to those parts referred to as "earplugs," which can be replaced upon wear or for hygiene reasons (e.g., when the earphone is given to another user).

[0097] In this variant, the interaction signal includes a pressure signal, and the processing device 11 is configured to detect the removal of at least one of the earpieces 2 based on the pressure signal (during the temporary injunction phase P4). This avoids unwanted calls within a certain period after the termination of the previous call.

[0098] As an alternative to or in combination with the foregoing, at least one of the earphones 2 and / or the mobile phone device 1 may include an audio acquisition device configured to sense pressure waves, preferably within the range of human hearing, in the environment surrounding the mobile device 1 and to generate an audio signal, preferably in a digital format. In this variant, the interaction signal includes the audio signal.

[0099] More specifically, the processing device 11 can be configured to detect any background noise in the audio signal (interaction signal) during the acquisition phase P2 and to block the call if the energy of the background noise exceeds a (second) threshold. This avoids making a call immediately after it has ended when the user is in a noisy environment; in such cases, it is practically difficult to speak and perceive audio signals from the telephone (e.g., ringtones, signals, etc.).

[0100] Of course, the examples described so far can have many variations.

[0101] While this description describes some possible variations of the invention, it will be apparent to those skilled in the art that other embodiments may also be implemented, and some elements may be replaced by other technically equivalent elements. Therefore, the invention is not limited to the exemplary examples described herein, as many modifications, improvements, or substitutions may be made to equivalent parts and elements without departing from the basic inventive spirit set forth in the following claims.

[0102] In one variant, when mobile phone device 1 is temporarily blocked from making outgoing calls, other functions of the device (such as ringing and other functions) can still be operated.

[0103] In another variation, mobile phone device 1 is configured to immediately exit the temporary call blocking state when the mobile phone device 1 is in motion, even if a predetermined period of time during which outgoing calls should be blocked has not yet passed, thereby changing the value of the directional signal.
