Description

  The present invention relates to a mobile terminal that automatically controls an operation mode in accordance with vibrations received by the mobile terminal.

  In recent years, portable terminals have been reduced in size and weight, and are easy to carry. Therefore, the portable terminal has the convenience that a user can use it for communication or a call at a destination, and is widely spread.

  For example, a user of a mobile terminal can use the mobile terminal while driving a moving body such as a train or a car at a predetermined speed. However, using a mobile terminal while driving a car may lead to an accident because the user's attention to driving is reduced. Therefore, the use of mobile terminals while driving is legally prohibited. In addition, when a mobile terminal is used in the presence of a large number of people such as in a train, noises such as ringtones, talking voices, and operation sounds of the mobile terminal are often annoying to the surroundings. In addition, the use of a portable terminal may cause functional damage to medical devices such as a cardiac pacemaker, and may cause great damage.

  For this reason, a technique for immediately stopping the ringtone and a technique for automatically controlling the operation mode of the mobile terminal while driving a moving body such as an automobile have been proposed.

  For example, Patent Document 1 discloses a technique for stopping a ringtone in a short time as much as possible when a ringtone of a mobile terminal sounds on a train.

  Specifically, Patent Document 1 is a mobile terminal equipped with an impact sensor. For example, when an incoming call is received at a mobile terminal in a bag, the user taps the mobile terminal from the outside of the bag. The impact sensor senses the impact and stops ringing of the ringing tone by giving an impact.

  However, in the portable terminal of the above-mentioned Patent Document 1, the ring tone sounds until the impact sensor is shocked after the ring tone starts to ring. In addition, the user needs to artificially impact the mobile terminal in order to stop the ring tone. Moreover, the portable terminal of the said patent document 1 cannot stop a function only by stopping a ringtone by receiving an impact. Therefore, for example, when the user turns off the portable terminal, it is necessary to take out the portable terminal and operate the portable terminal. Therefore, the user uses the portable terminal while driving a moving body such as an automobile. As a result, there is a risk of causing an accident.

  Therefore, in order to solve the above problem, it is not necessary for a user or the like to manually operate the mobile terminal, and a technique for automatically controlling the operation mode of the mobile terminal according to the moving state is required. Patent Document 2 discloses a technique for determining whether or not a mobile terminal is in a moving state and automatically changing the operation mode of the mobile terminal.

  Specifically, Patent Document 2 compares the acceleration data obtained from the acceleration received by the own device with the acceleration data associated with the operation mode stored in advance in the storage unit, and based on the determination result. The mobile terminal is controlled according to the operation mode associated with the acceleration data.

  However, since only the acceleration data is used in the configuration of Patent Document 2, it is possible to estimate whether or not the moving body is traveling, but it is difficult to estimate the type of the moving body. is there.

  Therefore, in addition to the technique of Patent Document 2, a technique for estimating the movement state (for example, the type of the moving body) of the own apparatus using the results of other sensors is disclosed in Patent Document 3.

Specifically, Patent Document 3 includes an acceleration sensor, an angular velocity sensor, an atmospheric pressure sensor, GPS, and a PHS, and uses measurement results of other sensors in addition to the measurement results of the acceleration sensor. Thus, the moving path of the own device and the moving object on which the own device is placed are estimated.
Japanese Patent Laid-Open No. 11-14326 (Publication date: February 12, 1999) JP 2001-144853 A (publication date May 25, 2001) JP 2002-48589 A (publication date: February 15, 2002)

  However, in the conventional configuration described above, in order to accurately estimate the movement state of the device itself, determination is made using measurement results of other sensors such as an angular velocity sensor, an atmospheric pressure sensor, GPS and PHS, in addition to the acceleration sensor. There is a need to. This is because, for example, when the situation where the mobile terminal is placed is determined based on the measurement result of only the acceleration sensor, for example, a moving state with a small acceleration change such as a train, a subway or a monorail, and a stationary state This is because it is difficult to distinguish them. Therefore, in the above conventional configuration, in order to estimate the situation where the mobile terminal is placed more accurately, it is necessary to estimate the measurement results of the acceleration sensor and the measurement results of other sensors in total.

  However, like the above conventional configuration. If the acceleration sensor is combined with other sensors to estimate the situation where the mobile terminal is placed, the number of components of the mobile terminal will increase, making it impossible to reduce the size and cost. There is a problem that it becomes high.

  The present invention has been made in view of the above-described problems, and can accurately estimate the situation where the mobile terminal is placed without increasing the configuration of the apparatus as compared with the prior art. An object of the present invention is to provide a portable terminal capable of performing control according to an estimation result.

  In order to solve the above problems, a mobile terminal according to the present invention includes a vibration detection unit that detects vibration received by the device itself, a spectrum conversion unit that converts a detection result of the vibration detection unit into frequency spectrum data, A data acquisition unit for acquiring the comparison frequency spectrum data from the storage means that stores the frequency spectrum data for comparison, which is the frequency spectrum data of the device, and the processing operation performed by the own device in association with each other; A determination unit that compares the spectrum data with each other to determine the degree of similarity between them, and a control that performs a processing operation associated with the comparison frequency spectrum data when the degree of similarity between the two is equal to or greater than a predetermined value. It is characterized by providing a part.

  According to the said structure, the portable terminal which concerns on this invention estimates the mobile body in which the said portable terminal is placed by converting the vibration which the said vibration detection part detected into frequency spectrum data.

  The frequency spectrum data is obtained by decomposing a signal (intensity of vibration, that is, a displacement amount caused by vibration) detected by the vibration detection unit according to frequency. That is, the vibration detection unit indicates a change in displacement caused by vibration according to a time change, and the spectrum conversion unit converts the detection result detected by the vibration detection unit into frequency spectrum data. The frequency spectrum data is superior in that a vibration specific to the object for detecting the vibration can be obtained as compared with the signal (detection result) detected by the vibration detecting means.

  The comparative frequency spectrum data is information on a frequency spectrum that appears characteristically when the vibration detecting means is attached to a specific target, for example. Specifically, for example, as the frequency spectrum data for comparison, frequency spectrum data based on vibrations specific to a running car (car) or frequency spectrum based on vibrations specific to a running train Data etc. are mentioned. The comparison frequency spectrum data is stored in the storage means in association with a specific processing operation among the processing operations performed by the mobile terminal.

  Specifically, when the user of the mobile terminal is driving a car, for safety reasons, it is preferable to prohibit the use of the mobile terminal. For example, the comparison frequency spectrum and the operation of the mobile terminal Is stored in the storage means in association with the processing operation for prohibiting.

  According to the above configuration, in the mobile terminal according to the present invention, the vibration detected by the vibration detection unit is converted into frequency spectrum data, and the frequency spectrum data is compared with the comparison frequency spectrum data. , Seeking the similarity between the two. If the similarity between the two is greater than or equal to a predetermined value, a processing operation associated with the comparison frequency spectrum data is performed.

  The comparison frequency spectrum data is, for example, frequency spectrum data peculiar to a certain mobile body, and the frequency spectrum data converted by the spectrum conversion means is similar to the comparison frequency spectrum data. If the mobile terminal is present, it can be estimated that the owner of the mobile terminal is likely to be on the moving body.

  Therefore, when it is determined that the frequency spectrum data is similar to the comparison frequency spectrum data (when the similarity is equal to or higher than a predetermined value), the processing operation associated with the comparison frequency spectrum data in advance. I do. Specifically, for example, when it is estimated from the matching between the frequency spectrum data and the comparison frequency spectrum data that the user of the mobile terminal is in a car, the use of the mobile terminal is prohibited. The processing operation can be performed as follows.

  In other words, with the above configuration, it is possible to estimate the situation where the mobile terminal is placed (the situation where the user using the mobile terminal is placed) using the frequency spectrum data. Compared with this, it is possible to estimate with more accuracy and detail.

  In addition, with the above-described configuration, for example, the situation where the user of the mobile phone is placed is not estimated from information on a plurality of devices such as position information such as GPS and acceleration information as in the past. However, since it can be estimated with high accuracy, it is not necessary to provide the plurality of devices. Thereby, a mobile phone can be reduced in size. In addition, since it is not necessary to provide a plurality of devices, it is possible to suppress an increase in cost by providing the plurality of devices.

  Further, the portable terminal according to the present invention associates the frequency spectrum data obtained by the spectrum conversion unit with the processing operation, and stores the frequency spectrum data in the storage unit as comparison frequency spectrum data. May be provided.

  According to the said structure, the frequency spectrum data obtained by the said spectrum conversion part can be memorize | stored in a memory | storage part as comparison frequency spectrum data which is a comparison object. Thereby, since the frequency spectrum data detected by the vibration detection unit of the mobile terminal can be used as the comparison frequency spectrum data, the situation where the mobile terminal is placed can be estimated more accurately.

  As a method of associating the frequency spectrum data with the processing operation, for example, the processing operation selected by the user may be associated with the frequency spectrum data. The predetermined processing operation and the frequency spectrum data may be associated with each other. May be associated.

  The portable terminal according to the present invention includes a vibration detection unit that detects vibrations received by the device, a spectrum conversion unit that converts a detection result of the vibration detection unit into frequency spectrum data, and the comparison frequency spectrum data.

The control means associates the comparison frequency spectrum data with the comparison frequency spectrum data based on the similarity determination result and the effective time zone determination result. Operation being operated may be configured to perform.

  According to the above configuration, in the mobile terminal according to the present invention, the storage unit associates the frequency spectrum pattern for comparison of the mobile object that the user uses for one day with the time zone information that the user uses the mobile object. It is possible to memorize the behavior pattern. And the said determination part determines the similarity of the frequency spectrum pattern of the mobile body which the user actually used, and the said comparison frequency spectrum pattern. Further, the control unit determines whether or not the time zone information stored in association with the comparison frequency spectrum pattern is the same as the current time.

  Since it is determined whether or not the processing operation is to be performed based on the two determination results, ie, the similarity determination between the two and the determination as to whether or not it is in the effective time zone, the processing operation is more detailed than in the past. Restricted / unrestricted settings can be made.

  According to said structure, information can be transmitted to an external device, if a similarity degree is more than predetermined value and it is in an effective time slot | zone. Therefore, for example, by setting the time zone that the user of the mobile terminal should not ride as the effective time zone, when the user gets on the mobile device and the time zone where the user should not be, This can be notified to an external device.

  Further, the mobile terminal according to the present invention includes voice sampling means for collecting surrounding voice, and voice spectrum conversion means for converting voice data collected by the voice sampling means into voice spectrum data which is frequency spectrum data. The storage means stores comparison frequency spectrum data and known voice spectrum data, which is specific voice spectrum data, in association with each other, and the determination means is similar to the voice spectrum data and the known voice spectrum data. The control means based on at least one similarity between the frequency spectrum data and the comparison frequency spectrum data and a similarity between the speech spectrum data and the known speech spectrum data. Is associated with the comparison frequency spectrum data. It may perform the processing operation that.

  According to the above configuration, the mobile terminal according to the present invention is not limited to the frequency spectrum data obtained from the vibration received by the mobile terminal, but the ambient sound such as the engine sound by the voice sampling unit provided in the mobile terminal. And the voice data can be converted into voice frequency spectrum data by the voice spectrum converter. And the said audio | voice frequency spectrum data and the frequency spectrum data obtained from the vibration which the said portable terminal received can be linked | related and memorize | stored in the said memory | storage part. Therefore, the portable terminal can estimate the state where the portable terminal is placed using not only the vibration received by the portable terminal but also ambient sounds. Thereby, the portable terminal which concerns on this invention can be compared with the structure which uses only the said frequency spectrum data for the state in which the said portable terminal is placed, and can estimate it with higher precision.

  In addition, the mobile terminal according to the present invention includes a call unit for making a call with the outside, and the storage unit stores a message indicating that a call cannot be made at present, and determining the similarity between the two Based on the result, the control unit may prohibit the processing operation in the calling unit, and may send the message to the request source of the call request when receiving a call request from the outside. .

  According to the above configuration, the mobile terminal according to the present invention having a calling unit such as a mobile phone is automatically connected to the other party when there is an incoming call when the user is moving on a mobile body that cannot use the calling unit. It is possible to send a message to the effect that the current call cannot be made. Therefore, the mobile terminal automatically prohibits the processing operation of the mobile terminal when the user is moving in a mobile body that cannot respond to incoming calls, such as a car, and automatically when there is an incoming call The reason can be communicated to the other party.

  As described above, the mobile terminal according to the present invention is compatible with a vibration detection unit that detects vibration received by the device as vibration data, a spectrum conversion unit that converts the vibration data into frequency spectrum data, and a specific movement state. A data acquisition unit that acquires the comparison frequency spectrum data from the storage means that stores the comparison frequency spectrum data and the operation mode performed by the device in association with each other, and the similarity between the frequency spectrum data and the comparison frequency spectrum data It is a structure provided with the determination part which determines a degree, and the control part which performs the operation mode linked | related with the said comparison frequency spectrum data, when the said determination result is more than predetermined value.

  The spectrum conversion unit 3 converts the signal detected by the vibration sensor 2 (vibration intensity, that is, the amount of vibration displacement) into frequency spectrum data decomposed by frequency. The above transformation is obtained by Fourier transformation.

  The configurations of the vibration sensor 2 and the spectrum conversion unit 3 will be described later in detail.

And the said memory | storage part 5 has memorize | stored the said frequency spectrum data for a comparison as related information linked | related with mobile body information and operation mode (processing operation).

  In the above description, the storage unit 5 describes the case where the comparison frequency spectrum data, the mobile object information, and the operation mode are associated and stored, but the present invention is not limited to this. .

The moving body information is information indicating the type of moving body such as an automobile or a train.

  In the present embodiment, the storage unit 5 is included in the memory 16 of the mobile terminal 1, but is not limited thereto. For example, the storage unit 5 may be configured outside the mobile terminal 1. In that case, the portable terminal 1 transmits and receives data included in the storage unit 5 via the wireless unit 14 (shown in FIG. 2).

  The determination unit 4 mainly determines the similarity between the frequency spectrum data converted by the spectrum conversion unit 3 and the comparison frequency spectrum data stored in the storage unit 5.

Then, the type of the moving body, the comparison frequency spectrum data, and the operation mode are associated with each other and stored in the storage unit 5.

  In addition, in this embodiment, although the kind of mobile body is matched, this invention is not limited to this. That is, at least the frequency spectrum data and the operation mode may be stored in the storage unit 5 in association with each other.

  As described above, the mobile terminal 1 according to the present invention detects vibrations received by the mobile terminal 1 from the mobile body and estimates the type of mobile body on which the mobile terminal 1 is placed.

  Here, the vibration which the portable terminal 1 which concerns on this invention detects is demonstrated.

  The mobile terminal 1 estimates the type of the moving body by collecting periodic vibrations generated by the movement of the moving body such as a person or a car, that is, a periodic repetitive motion. The movement of the moving body means, for example, that when a person moves by walking or running, repeatedly moving the feet forward. Moreover, when a car or a bicycle moves, it moves by repeating the rotational movement of four wheels or two wheels. That is, the movement of the moving body is a periodic repetitive motion, and the portable terminal 1 receives a periodic vibration due to the periodic repetitive motion.

  Further, as shown in FIG. 3, the types of moving objects include automobiles, trains, buses, users running, users walking, bicycles, additional stored frequency spectrum data for comparison, and the like. Can be mentioned. And each moving body mentioned above has the periodic vibration peculiar to a moving body, respectively.

  That is, the mobile terminal 1 according to the present invention estimates the type of the mobile body using vibrations specific to each mobile body received by the mobile terminal 1.

  Further, the mobile terminal 1 detects vibrations peculiar to each mobile body received by the mobile terminal 1 as vibration data, converts it into frequency spectrum data, and uses it for estimation of the mobile body. Note that the vibration data represents the strength of the signal that changes with time (vibration strength), and the frequency spectrum data is obtained by decomposing the signal data according to the frequency, depending on the frequency. This represents the strength of the signal (vibration strength).

  In general, a signal is composed of various frequency components. However, in the vibration data, since the frequency components are synthesized, detailed information of the signal obtained from the vibration received by the mobile terminal 1 is not known. In order to solve the above problem, the portable terminal 1 converts the vibration data into the frequency spectrum data by Fourier transform. By the above conversion, the strength of the signal for each frequency component of the vibration can be known, so that the vibration specific to the moving body becomes clear.

  The Fourier transform is to divide an electric signal composed of various frequency components into sine wave components having various frequencies.

  As described above, the portable terminal 1 according to the present invention converts the vibration data received into the frequency spectrum data by using the vibration received by the portable terminal 1 from the moving body as signal data, and thus compared with the conventional configuration. It is possible to estimate the type of moving object with high accuracy.

  Here, the configuration of the vibration sensor 2 and the spectrum conversion unit 3 which are the most main components of the mobile terminal 1 will be described in detail.

  FIG. 4 is a diagram showing the direction of the vibration axis of the vibration sensor 2.

  The vibration sensor 2 detects periodic vibration generated by the above-described periodic repetitive movement for movement. The vibration axis of the vibration sensor 2 is composed of three axes of X, Y, and Z. As described above, the vibration sensor 2 can detect the vertical and horizontal movements as long as the vibration axes are three axes of X, Y, and Z. Therefore, the vibration sensor 2 can detect the vibration received by the mobile terminal 1 from the movement of the user and the moving body with high accuracy.

  In the following description, the case of using the vibration sensor 2 that can detect the vibration in the triaxial direction is described. However, as the vibration sensor 2, for example, the vibration in the biaxial direction can be detected. There is no particular limitation.

  FIG. 5 is a block diagram showing the configuration of the vibration sensor 2 and the spectrum conversion unit 3.

  As shown in FIG. 5, the vibration sensor 2 includes an X-axis vibration sensor 2a, a Y-axis vibration sensor 2b, a Z-axis vibration sensor 2c, an X-axis amplifier 2d, a Y-axis amplifier 2e, and a Z-axis amplifier 2f. It has. Further, the spectrum conversion unit 3 includes an X-axis frequency conversion unit 3a, a Y-axis frequency conversion unit 3b, a Z-axis frequency conversion unit 3c, and a frequency characteristic storage unit 3d.

  The configuration from when the vibration sensor 2 having the above configuration detects the vibration received by the mobile terminal 1 as vibration data until the spectrum conversion unit 3 converts the vibration data into a frequency spectrum is described with reference to FIG. explain.

  First, each X, Y, Z axis vibration sensor 2a, 2b, 2c detects the X, Y, Z axis direction component of the vibration received by the mobile terminal 1, and each X, Y, Z axis amplifier as vibration data. 2d, 2e, 2f. Note that the vibration detected by each axis vibration sensor 2 is obtained as vibration data that is the strength of a signal (vibration strength) that changes with time.

  Next, each of the X, Y, and Z axis amplifiers 2d, 2e, and 2f amplifies the vibration data of the X, Y, and Z axis direction components, and transmits the amplified vibration data to the spectrum conversion unit 3. .

  The X, Y, and Z axis frequency converters 3a, 3b, and 3c of the spectrum converter 3 convert the amplified vibration data in the X, Y, and Z axis directions into frequency spectrum data. And each said X, Y, Z-axis spectrum conversion part 3a, 3b, 3c transmits each said frequency spectrum data converted into the frequency characteristic memory | storage part 3d.

  The frequency characteristic storage unit 3d temporarily stores the frequency spectrum data (frequency characteristics).

  In this way, the mobile terminal 1 can obtain frequency spectrum data for estimating the type of mobile object on which the mobile terminal 1 is placed.

  That is, the portable terminal 1 uses the frequency spectrum data temporarily stored in the frequency characteristic storage unit 3d, and the determination unit 4 determines the similarity between the frequency spectrum data and the comparison frequency spectrum data. By doing so, the type of the mobile object on which the mobile terminal 1 is placed is estimated.

  Here, with reference to FIG. 1, a description will be given of a configuration from when the mobile terminal 1 detects the vibration received by itself until it estimates the type of mobile object on which the mobile terminal 1 is placed.

  First, the vibration sensor 2 detects the vibration received by the mobile terminal 1 as vibration data. Then, the spectrum conversion unit 3 converts the vibration data detected by the vibration sensor 2 into frequency spectrum data. Since the configuration from when the vibration sensor 2 detects vibration as vibration data until the spectrum conversion unit 3 converts the vibration data into frequency spectrum data is as described above, detailed description is omitted.

  Next, the data acquisition unit 4 a acquires the comparison frequency spectrum data stored in the storage unit 5. The storage unit 5 stores the frequency spectrum data for comparison in association with mobile object information and an operation mode.

  Then, the frequency spectrum data comparison unit 4 b determines the similarity between the frequency spectrum data converted by the spectrum conversion unit 3 and the comparison frequency spectrum data acquired from the storage unit 5. The similarity determination method has been described above, and a description thereof will be omitted here.

  When the similarity between the frequency spectrum data and the comparison frequency spectrum data is greater than or equal to a predetermined value, the frequency spectrum data comparison unit 4b displays the similarity that is greater than or equal to the predetermined value with the frequency spectrum data. The operation mode associated with the frequency spectrum data is transmitted to the process control unit 6.

  Then, the process control unit 6 does not depend on the operation unit 7 according to the operation mode associated with the comparison frequency spectrum data received from the frequency spectrum data comparison unit 4b, and the communication control unit 8, the voice processing unit 11, The display unit 10 and the power supply control unit 11 are controlled.

  The operation mode controlled by the processing control unit 6 includes transmission of a message stored in the memory 16 by the communication control unit 8 in advance, stop of the ringtone by the voice processing unit 11, and display of the operation mode by the display unit 10. And the power supply control unit 11 stops the power supply.

  The mobile terminal 1 uses the frequency spectrum data comparison unit 4b to determine the similarity between the frequency spectrum data and the comparison frequency spectrum data, in order to determine the similarity between the frequency spectrum data and the comparison frequency spectrum data. It is preferable that the data is extracted. The portable terminal 1 according to the present embodiment has a configuration in which the determination unit 4 extracts data from both frequency spectrum data. However, the present invention is not limited to this, and the spectrum conversion unit 3 extracts data from the frequency spectrum data, and the storage unit 5 stores the data extracted from the comparison frequency spectrum data. It may be a configuration.

  Here, a configuration in which the mobile terminal 1 according to the present embodiment changes the function of the mobile terminal 1 to the operation mode associated with the comparison frequency spectrum data will be described.

  When a user is driving a car, it is preferable to prohibit the use of a portable terminal for safety. However, when the user is on the Shinkansen, the Shinkansen is provided with a place where the mobile terminal can be used. Therefore, it is preferable to restrict the function rather than prohibiting the use of the mobile terminal.

  That is, the operation mode of the moving body suitable for the user differs depending on the type of moving body used by the user. Therefore, the portable terminal 1 is a structure which can set an operation mode suitably according to each moving body.

  FIG. 6 is an operation mode change table showing the setting of the operation mode of the mobile terminal 1. The above-described operation mode change table indicates the operation mode associated with each comparison frequency spectrum data among the data structure in which the mobile object information, the comparison frequency spectrum data, and the operation mode are associated with each other as shown in FIG. It is described. That is, in the operation mode change table, the comparison frequency spectrum data of the moving body and the operation mode are associated with each other and stored in the storage unit 5.

  Moreover, as an operation mode that can be set, for example, there are a function stop of the mobile terminal and a manner mode. In both the operation modes, the user can select whether or not to transmit the message stored in the portable terminal 1 to the communication partner side. By switching ON and OFF of the above three operation modes, it is possible to set an operation mode of the moving body suitable for the user.

  Hereinafter, with reference to FIG. 6, an example of setting the three operation modes for the comparison frequency spectrum data of each mobile unit will be described.

  For the frequency spectrum data for vehicle comparison, the operation mode is set to ON, the function stop mode is set to ON, the manner mode is set to OFF, and the message transmission is set to ON.

  When the frequency spectrum data comparison unit 4b estimates that the similarity between the frequency spectrum data and the comparison frequency spectrum data of the vehicle is equal to or greater than a predetermined value, the function of the mobile terminal 1 is stopped. And the said portable terminal 1 can transmit the message to the effect of being unable to respond to an incoming call with respect to the communicating party side, when there exists an incoming call.

  In the same manner, the operation mode, the function stop mode is set to OFF, the manner mode is set to ON, and the message transmission is set to ON for the frequency spectrum data for comparison of trains.

  For bus spectrum frequency spectrum data, the operation mode is set to OFF, the function stop mode is set to OFF, the manner mode is set to ON, and the message transmission is set to ON.

  For the comparison frequency spectrum data when the user is running, the operation mode is set to OFF, the function stop mode is set to OFF, the manner mode is set to OFF, and the message transmission is set to OFF.

  For the comparison frequency spectrum data when the user is walking, the operation mode is set to OFF, the function stop mode is set to OFF, the manner mode is set to OFF, and the message transmission is set to OFF.

  For the comparison frequency spectrum data of the bicycle, the operation mode is set to OFF, the function stop mode is set to OFF, the manner mode is set to OFF, and the message transmission is set to OFF.

  The mobile terminal 1 can also set an arbitrary operation mode for the additionally stored mobile frequency spectrum data for comparison. Note that a method for additionally storing the frequency spectrum data for comparison of the moving object will be described later, and will be omitted here.

  In FIG. 6, for example, the types of additionally stored mobile objects are a case where a ship and a car are traveling on a highway, and a bullet train.

  For the frequency spectrum data for ship comparison, the operation mode is set to OFF, the function stop mode is set to OFF, the manner mode is set to ON, and the message transmission is set to OFF.

  The operation mode, the function stop mode is set to ON, the manner mode is set to OFF, and the message transmission is set to ON for the frequency spectrum data for comparison while traveling on the highway by a car.

  For the comparison frequency spectrum data of the Shinkansen, the operation mode is set to OFF, the function stop mode is set to OFF, the manner mode is set to ON, and the message transmission is set to OFF.

  Thus, the portable terminal 1 can set the operation mode suitable for the user for the comparison frequency spectrum data of each mobile unit.

  In the function change use mode setting field, whether to change to the set operation mode can be determined by switching between ON and OFF. If the function change use mode is set to OFF, the operation mode set in advance in the mobile terminal 1 is set.

  Further, at the time of switching the operation mode or when the function of the mobile terminal is stopped, the mobile terminal 1 displays a message such as “functional restriction” on the display unit 10 or outputs the message from the speaker 24 by voice. It may be configured.

  In the present embodiment, as a method of associating the frequency spectrum data with the operation mode, the operation mode selected by the user is associated with the frequency spectrum data, but the present invention is not limited to this. That is, the mobile terminal 1 may associate a predetermined operation mode with the frequency spectrum data.

  FIG. 7 is a flowchart in which the mobile terminal 1 changes the operation mode according to the moving object after the operation mode setting of the mobile terminal 1 is changed.

  As described with reference to FIG. 6, the mobile terminal 1 changes the settings of various functions of the mobile terminal 1 to a suitable operation mode according to each mobile object. Thereafter, when the mobile terminal 1 receives vibration, the mobile terminal 1 changes various functions according to the set operation mode. Hereinafter, a configuration from when the vibration sensor 2 detects vibration received by the device itself until the various functions of the mobile terminal 1 are changed according to the set operation mode will be described with reference to FIG.

  First, the vibration sensor 2 collects the vibration received by the mobile terminal 1 as vibration data (S1). Then, the spectrum conversion unit 3 converts the collected vibration data into frequency spectrum data (S2).

  Next, the data acquisition unit 4a acquires frequency spectrum data for comparison of each moving object from the storage unit 5 (S3).

  Next, the frequency spectrum data comparison unit 4b compares the frequency spectrum data with the acquired frequency spectrum data for comparison (S4).

  First, the frequency spectrum data comparison unit 4b compares the frequency spectrum data with the comparison frequency spectrum data corresponding to the automobile stored in advance in the storage device (S5).

  Next, when the frequency spectrum data comparison unit 4b estimates that the moving body is not an automobile (No in S5), the frequency spectrum data comparison unit 4b compares the frequency spectrum data with the train that is the next moving body. The frequency spectrum data is compared (S6).

  Next, when the frequency spectrum data comparison unit 4b estimates that the moving body is not a train (No in S6), the frequency spectrum data comparison unit 4b compares the frequency spectrum data with the bus that is the next moving body. The frequency spectrum data is compared (S7).

  Next, when the frequency spectrum data comparison unit 4b estimates that the mobile body is not a bus (No in S7), the frequency spectrum data comparison unit 4b receives the frequency spectrum data from the user who is the next mobile body. The frequency spectrum data for comparison when running is compared (S8).

  Next, when the frequency spectrum data comparison unit 4b estimates that the user is not running (No in S8), the frequency spectrum data comparison unit 4b sends the frequency spectrum data to the next mobile object. The frequency spectrum data for comparison when a certain user is walking is compared (S9).

  Next, when the frequency spectrum data comparison unit 4b estimates that the user is not walking (No in S9), the frequency spectrum data comparison unit 4b sends the frequency spectrum data to the next mobile object. A comparison is made with comparative frequency spectrum data of a certain bicycle (S10).

  Next, when the frequency spectrum data comparison unit 4b estimates that the moving body is not a bicycle (No in S10), the frequency spectrum data comparison unit 4b stores the frequency spectrum data in the additional storage corresponding to the next moving body. The comparison frequency spectrum data is compared (S11).

  As described above, when S5 to S11 indicate Yes, that is, when the comparison frequency spectrum data compared with the frequency spectrum data shows a similarity equal to or higher than a predetermined value, the following processing is performed.

  First, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data indicates a similarity equal to or higher than a predetermined value with the comparison frequency spectrum data of the automobile (Yes in S5), the process control unit 6 The terminal 1 is controlled to the operation mode corresponding to the comparison frequency spectrum data of the automobile (S12).

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data indicates a similarity equal to or higher than a predetermined value with the frequency spectrum data for train comparison (Yes in S6), the processing control unit 6 The portable terminal 1 is controlled to an operation mode corresponding to the frequency spectrum data for comparison of trains (S13).

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data shows a similarity equal to or higher than a predetermined value with the frequency spectrum data for bus comparison (Yes in S7), the processing control unit 6 The portable terminal 1 is controlled to an operation mode corresponding to the bus comparison frequency spectrum data (S14).

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data indicates a similarity equal to or higher than a predetermined value with the frequency spectrum data for comparison when the user is running (Yes in S8), The process control unit 6 controls the mobile terminal 1 to an operation mode corresponding to the comparison frequency spectrum data when the user is running (S15).

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data indicates a similarity equal to or higher than a predetermined value with the frequency spectrum data for comparison when the user is walking (Yes in S9), The process control unit 6 controls the mobile terminal 1 to an operation mode corresponding to the frequency spectrum data for comparison when the user is walking (S16).

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data shows a similarity equal to or higher than a predetermined value with the frequency spectrum data for bicycle comparison (Yes in S10), the process control unit 6 The portable terminal 1 is controlled to an operation mode corresponding to the comparative frequency spectrum data of the bicycle (S17).

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data indicates a similarity equal to or greater than a predetermined value with the additionally stored comparison frequency spectrum data (Yes in S11), the processing control unit 6 controls the portable terminal 1 to the operation mode corresponding to the added frequency spectrum data for comparison (S18).

  Moreover, after S12-S18, the process control part 6 changes the portable terminal 1 to the operation mode according to the estimated mobile body, and in S5-S11, the frequency spectrum data comparison part 4b is which mobile body. If both cannot be estimated, the portable terminal 1 returns to S1 and again collects vibrations received by itself.

  As described above, the mobile terminal 1 according to the present embodiment is compared with the vibration sensor 2 that detects the vibration received by the device itself, the spectrum conversion unit 3 that converts the detection result of the vibration sensor 2 into frequency spectrum data, and the comparison. The data acquisition means 4a for acquiring the comparison frequency spectrum data from the storage unit 5 that stores the comparison frequency spectrum data that is the object and the operation mode performed by the device itself, and the frequency spectrum data and the comparison frequency spectrum. A determination unit 4 that compares the data to determine the similarity between the two and a control that performs an operation mode associated with the comparison frequency spectrum data when the similarity between the two is equal to or greater than a predetermined value. And means.

  According to the above configuration, the vibration sensor 2 detects the vibration received by the mobile terminal 1 as vibration data. The spectrum conversion unit 3 converts the vibration data detected by the vibration sensor 2 into frequency spectrum data. Since the configuration from when the vibration sensor 2 detects vibration as vibration data until the spectrum conversion unit 3 converts the vibration data into frequency spectrum data is as described above, detailed description is omitted.

  Next, the data acquisition unit 4 a acquires the comparison frequency spectrum data stored in the storage unit 5. The storage unit 5 stores the comparison frequency spectrum data in association with the mobile object information and the operation mode.

  Then, the frequency spectrum data comparison unit 4 b determines the similarity between the frequency spectrum data converted by the spectrum conversion unit 3 and the comparison frequency spectrum data acquired from the storage unit 5. Since the method for determining the similarity is described above, the description thereof is omitted here.

  When the similarity between the frequency spectrum data and the comparison frequency spectrum data is greater than or equal to a predetermined value, the frequency spectrum data comparison unit 4b displays the similarity that is greater than or equal to the predetermined value with the frequency spectrum data. The operation mode associated with the frequency spectrum data is transmitted to the process control unit 6.

  Then, the processing control unit 6 does not depend on the operation unit 7 according to the operation mode associated with the comparison frequency spectrum data received from the frequency spectrum data comparison unit 4b, and the communication control unit 8 and the voice processing unit 11 The display unit 10 and the power supply control unit 11 are controlled.

  Note that the operation modes controlled by the processing control unit 6 include, for example, a function stop of the mobile terminal and a manner mode as shown in FIG. Further, it is possible to set whether or not to transmit a message stored in the portable terminal 1 to the communication partner in both the operation modes. Below, the method in which the process control part 6 controls the function of the portable terminal 1 to each operation mode is demonstrated.

  First, when the function of the portable terminal 1 is stopped, the processing control unit 6 causes the communication control unit 8 to stop transmission / reception of radio waves. Further, the processing control unit 6 may stop the power supply control unit 11 from supplying current from the battery 13 to the circuit unit of the portable terminal 1 that is not used.

  Further, the function of the portable terminal 1 may be set to a standby state, that is, a so-called standby mode, instead of stopping the function of the portable terminal 1.

  When the mobile terminal 1 is set to the manner mode, the processing control unit 6 causes the voice processing unit 9 to stop ringing.

  In both the operation modes, when a call request is received from the outside, the processing control unit 6 displays a message indicating that the communication control unit 8 cannot respond to the current incoming call stored in the memory 16. It may be configured to transmit to the other party.

  The main control unit 6 may be configured to display the current operation mode on the display unit 10 when controlling the operation mode of the mobile terminal 1 as described above.

  As described above, the mobile terminal according to the present invention includes the communication control unit 8 for making a call with the outside, and the storage unit 5 of the memory 16 stores a message indicating that a call cannot be made at present. When the similarity between the two is equal to or greater than a predetermined value, the control unit 6 prohibits the operation mode in the communication control unit 8, and when a call request is received from the outside, the request source of the call request The above message may be transmitted.

  According to the above configuration, when the mobile terminal 1 according to the present invention including a calling unit such as a mobile phone is moving on a mobile body in which the user cannot use the calling unit, the other party automatically receives an incoming call. It is possible to send a message to the side that the telephone call cannot be made. Therefore, the mobile terminal 1 automatically prohibits the function of the mobile terminal 1 when the user is moving with a mobile body that cannot respond to incoming calls, such as a car, and automatically when there is an incoming call. The reason can be communicated to the other party.

  As described above, the portable terminal 1 according to the present invention estimates the moving object on which the portable terminal 1 is placed by converting the vibration detected by the vibration sensor 2 into frequency spectrum data.

  The frequency spectrum data is obtained by decomposing a signal detected by the vibration sensor 2 (the intensity of vibration, that is, the amount of displacement caused by vibration) by frequency. That is, the vibration sensor 2 shows a change in displacement caused by vibration according to a time change, and the spectrum conversion unit 3 converts the detection result detected by the vibration sensor 2 into frequency spectrum data. The frequency spectrum data is superior to the signal (detection result) detected by the vibration sensor 2 in that vibration specific to the object for detecting vibration can be obtained.

  The comparative frequency spectrum data is information on a frequency spectrum that appears characteristically when the vibration sensor 2 is attached to a specific target, for example. Specifically, for example, as the frequency spectrum data for comparison, frequency spectrum data based on vibrations specific to a traveling car, frequency spectrum data based on vibrations specific to a running train, etc. Can be mentioned. The comparison frequency spectrum data is stored in the storage unit 5 in association with a specific operation mode among the operation modes performed by the mobile terminal 1.

  Specifically, when the user of the mobile terminal 1 is driving a car, for safety reasons, it is preferable to prohibit the use of the mobile terminal. For example, the comparison frequency spectrum and the mobile terminal 1 An operation mode for prohibiting the operation is associated with and stored in the storage unit.

  According to said structure, in the portable terminal 1 which concerns on this invention, the vibration which the said vibration sensor 2 detected is converted into frequency spectrum data, and this frequency spectrum data and comparison frequency spectrum data are compared. Therefore, the similarity between the two is obtained. When the similarity between the two is equal to or greater than a predetermined value, an operation mode associated with the comparison frequency spectrum data is performed.

  The comparison frequency spectrum data is, for example, frequency spectrum data peculiar to a certain mobile body, and the frequency spectrum data converted by the spectrum conversion means is similar to the comparison frequency spectrum data. When the mobile terminal is present, it can be estimated that the user of the mobile terminal 1 is highly likely to be on the moving body.

  Therefore, when it is determined that the frequency spectrum data is similar to the comparison frequency spectrum data (when the similarity is equal to or greater than a predetermined value), the operation mode associated with the comparison frequency spectrum data in advance. I do. Specifically, for example, when it is estimated that the user of the mobile terminal is in a car based on the matching between the frequency spectrum data and the comparison frequency spectrum data, the use of the mobile terminal 1 is determined. An operation mode can be performed to prohibit.

  That is, with the above configuration, it is possible to estimate the situation where the portable terminal 1 is placed (the situation where the user using the portable terminal is placed) using the frequency spectrum data. Can be estimated more accurately and in detail than.

  In addition, with the above-described configuration, for example, the situation where the user of the mobile phone is placed is not estimated from information on a plurality of devices such as position information such as GPS and acceleration information as in the past. However, since it can be estimated with high accuracy, it is not necessary to provide the plurality of devices. Thereby, a mobile phone can be reduced in size. In addition, since it is not necessary to provide a plurality of devices, it is possible to suppress an increase in cost by providing the plurality of devices.

  Further, in the mobile terminal 1 according to the present embodiment, the storage unit 5 stores comparison frequency spectrum data corresponding to the vibrations of a plurality of moving bodies. However, the storage unit 5 can additionally store frequency spectrum data corresponding to new vibrations of the moving body as comparison frequency spectrum data. For this purpose, the mobile terminal 1 needs to collect vibrations received by the mobile terminal 1 from a mobile body for additional storage.

  Further, a means for storing the frequency spectrum data collected by the portable terminal 1 in the storage unit 5 is necessary. FIG. 8 is a block diagram illustrating a schematic configuration of the determination unit 4. With reference to FIG. 8, the means for storing the frequency spectrum data in the storage unit 5 will be described.

  According to FIG. 8, the determination unit 4 adds to the data acquisition unit 4a that acquires data from the storage unit 5 and the frequency spectrum data comparison unit 4b that determines the similarity between the frequency spectrum data and the comparison frequency spectrum data. The storage instruction unit 4c is provided.

  The storage command unit 4 c is for storing various data by the determination unit 4 in the storage unit 5. Specifically, it functions when the frequency spectrum data converted by the spectrum conversion unit 3 is stored as comparison frequency spectrum data.

  In this embodiment, the storage command unit 4c is included in the determination unit 4, but is not limited thereto. That is, it should just be contained in the portable terminal 1 which concerns on this invention.

  FIG. 9 is a flowchart for storing frequency spectrum data in the storage unit 5 as comparison frequency spectrum data.

  The configuration from when the mobile terminal 1 collects the vibration of the target moving body received by the mobile terminal 1 as vibration data until it is stored in the storage unit 5 as comparison frequency spectrum data is shown in FIG. To explain.

  First, the vibration sensor 2 collects vibration data of a target moving body (S19).

  Next, the spectrum conversion unit 3 converts the collected vibration data into frequency spectrum data (S20).

  Next, the determination unit 4 associates the frequency spectrum data with the operation mode (S21).

  Then, the determination unit 4 stores the frequency spectrum data as comparison frequency spectrum data in the storage unit 5 via the storage command unit 4c (S22).

  With the above configuration, the mobile terminal 1 can store the frequency spectrum data obtained by the spectrum conversion unit 3 in the storage unit 5 as comparison frequency spectrum data to be compared. Thereby, since the frequency spectrum data detected by the vibration sensor 2 of the portable terminal 1 can be used as the comparative frequency spectrum data, the situation where the portable terminal 1 is placed can be estimated more accurately. .

  Moreover, as a kind of moving body, a monorail, a ship, etc. may be mentioned besides the moving body quoted in FIG. At this time, when the frequency spectrum data peculiar to these mobile objects is stored in the storage unit 5, it is possible to estimate the types of these mobile objects.

  Even in the case of the same moving body, the frequency spectrum data varies depending on the moving state of the moving body (for example, when the automobile travels on a highway or travels on a mountain road). At this time, if the frequency spectrum data is stored in the storage unit 5 for each moving state of the moving body, the moving state of the moving body can be estimated.

  As a method of associating the frequency spectrum data with the operation mode, for example, the operation mode selected by the user may be associated with the frequency spectrum data. The predetermined operation mode and the frequency spectrum data may be associated with each other. You may associate.

  The storage unit 5 may be configured to store audio frequency spectrum data obtained from ambient sounds such as engine sounds collected from the microphone 23 in association with the frequency spectrum data.

  Hereinafter, a configuration from when the microphone 23 collects ambient sounds as audio data to when the audio frequency spectrum data obtained from the audio data is stored in the storage unit 5 will be described.

  First, the microphone 23 collects ambient sound as audio data, and transmits the collected audio data to the audio processing unit 11 (see FIGS. 1 and 2).

  Then, the sound processing unit 11 (see FIGS. 1 and 2) removes noise from the sound data, and transmits the sound data from which the noise has been removed to the sound spectrum conversion unit.

  Then, the audio spectrum conversion unit converts the received audio data into audio frequency spectrum data, and transmits the converted audio frequency spectrum data to the determination unit 4.

  Then, the determination unit 4 associates the frequency spectrum data obtained from the vibration and the audio frequency spectrum data obtained from the ambient sound, and stores them in the storage unit 5 via the storage command unit 4c.

  In addition, although this embodiment demonstrated the structure which provided the audio | voice spectrum conversion part, this invention is not limited to this. That is, the structure using the spectrum conversion unit 3 as the sound spectrum conversion unit may be employed without providing the sound spectrum conversion unit individually.

  Further, the storage unit 5 may be configured to detect the current position information of the mobile terminal 1 using the GPS function unit 25 and the RFID reader 26 and store the frequency spectrum data and the position information in association with each other. Good.

  As described above, the mobile terminal 1 according to the present invention includes the microphone 23 that collects the surrounding sound, and the sound spectrum conversion unit that converts the sound data collected by the microphone 23 into the sound spectrum data that is the frequency spectrum data. The storage unit 5 is associated with frequency spectrum data for comparison and known speech spectrum data which is specific speech spectrum data, and the determination unit 4 is similar to the speech spectrum data and the known speech spectrum data. When the similarity between the frequency spectrum data and the comparison frequency spectrum data and at least one similarity between the speech spectrum data and the known speech spectrum data is greater than or equal to a predetermined value. In this case, the processing control unit 6 is paired with the comparison frequency spectrum data. Operation modes that are attached or may be performed.

  According to the above-described configuration, the mobile terminal 1 according to the present invention can output not only the frequency spectrum data obtained from the vibration received by the device itself but also the ambient sound such as engine sound by the microphone 23 provided in the mobile terminal 1. It can be sampled as data, and the voice spectrum conversion unit can convert the voice data into voice frequency spectrum data. The storage unit 5 can store the audio frequency spectrum data and the frequency spectrum data obtained from the vibration received by the mobile terminal 1 in association with each other. Therefore, the portable terminal 1 can estimate the state where the mobile device 1 is placed by using not only the vibration received by the mobile device 1 but also ambient sounds. Thereby, the portable terminal 1 which concerns on this invention can be compared with the structure which uses only the said frequency spectrum data for the state in which an own apparatus is placed, and can estimate it with higher precision.

  Moreover, the portable terminal 1 can associate and set the mobile body which a user uses, and the time slot | zone to be used, and can memorize | store the user's action of a day in the memory | storage part 5 as an action pattern in detail. .

  FIG. 10 is an action pattern setting table showing the setting of the daily action pattern of the user. Hereinafter, a behavior pattern setting method will be described with reference to FIG.

  The behavior pattern setting table is associated with time zone information in addition to the data structure shown in FIG. 3 in which the mobile object information, the comparison frequency spectrum data, and the operation mode are associated. That is, in the behavior pattern setting table, the comparison frequency spectrum data of the moving body and the time zone information are associated and stored in the storage unit 5.

  In the behavior pattern setting table, the mobile body used by the user can be determined by switching the setting column between ON and OFF. In other words, the setting of the action pattern setting table according to the user is set by setting the setting field of the moving object used by the user to ON and setting the setting field of the moving object not used by the user to OFF. It can be carried out. In the time 1 and time 2 fields, the time zone in which the user uses the moving body can be set by entering the time zone in which the set mobile body is used.

  In addition, by using a configuration that can set two time zones, such as time 1 and time 2, when moving objects are used twice a day, such as commuting to work or school , Can be preferably used.

  For example, if the mobile field is a train, the setting field is set to ON, the time 1 field is set to 8:00 to 9:00, and the time 2 field is set to 16:00 to 17:00. When the mobile unit column is a bus, the setting column is turned ON, the time 1 column is set to 7:30 to 8:00, and the time 2 column is set to 17: 0 to 17:30.

  As a result, the user uses the bus from 7:30 to 8:00 in the morning and train from 8:00 to 9:00 in the morning for commuting and attending school, and the train on the way back from 16: 00 to 17: It is possible to set an action pattern of using the bus from 17:00 to 17:30 until 00.

  It should be noted that the action pattern use setting field can determine whether or not to use the action pattern set as described above by switching between ON and OFF.

  As described above, the user's daily action is stored in the storage unit 5 as an action pattern by setting the mobile object that the user uses for the day and the time zone used by the mobile object. be able to.

  As described in FIG. 10, the storage unit 5 can store the frequency spectrum data of the moving body used by the user and the time zone in which the moving body is used in association with each other as an action pattern.

  In addition, the mobile terminal 1 can compare the behavior pattern stored in the storage unit 5 with the daily behavior of the user. Below, the structure which compares the action pattern which the memory | storage part 5 has memorize | stored with a user's 1 day action is demonstrated with reference to FIG. FIG. 11 is a flowchart for comparing the behavior pattern set in FIG. 10 with the actual user behavior.

  In the flowchart of FIG. 11, the configuration from when the mobile terminal 1 detects the vibration of the mobile body to the comparison with the comparison frequency spectrum data of each mobile body is the same as the configuration of S <b> 1 to S <b> 11 of FIG. 7. Therefore, the same reference numerals are given and the description is omitted.

  As shown in FIG. 11, in S5 to S11, the frequency spectrum data comparison unit 4b determines the degree of similarity between the frequency spectrum data of the mobile object on which the mobile terminal 1 is placed and the comparison frequency spectrum data.

  Next, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data indicates a similarity equal to or higher than a predetermined value with the frequency spectrum data for comparison of each moving body (Yes in S5 to S11). Then, the estimation result is transmitted to the process control unit 6. Then, the processing control unit 6 uses the behavior pattern stored in the storage unit 5 to obtain the time zone information corresponding to the comparison frequency spectrum data estimated to show a similarity of a predetermined value or more based on the estimation result. Obtained via the obtaining unit 4a. Then, the process control unit 6 compares the time information with the time zone information obtained by the timer 22 (S23).

  Further, in S5 to S11, when the frequency spectrum data comparison unit 4b estimates that the frequency spectrum data does not show a degree of similarity equal to or higher than a predetermined value with the comparison frequency spectrum data of each mobile unit (in S5 to S11) No), the process in the portable terminal 1 returns to S1 and again collects vibrations received by the own device.

  In S23, when the process control unit 6 estimates that the current user's moving body and time information are the same as the action pattern stored in the storage unit 5 (Yes in S23), the mobile terminal 1 The processing in step S1 returns to S1 and again picks up vibrations received by the own device.
