Description

  The present invention relates to an information terminal device such as a mobile phone or a personal computer, a control method for the device, a control program for the device, and a recording medium on which the program is recorded.

  In general, in a mobile communication terminal device, when an incoming call is received, the incoming call is notified by a ringing tone or vibration, but there are cases where the incoming call is not noticed for various reasons while moving or away from the terminal. Even if the manner mode is set, it is difficult to notice an incoming call.

  In such a case, in order to check whether there is an unanswered incoming call by the user himself / herself, the terminal must be taken out and the incoming call history must be confirmed by viewing the screen or operating the terminal.

In order to eliminate the hassle of having to operate just to check whether there is such an incoming call, the conventional mobile communication terminal device is provided with a touch sensor, and the touch sensor senses contact. When there is an incoming call, the presence is notified by vibrating the terminal when there is an unanswered incoming call (see JP 2002-325115 A). Therefore, the presence of an unanswered incoming call can be confirmed simply by touching the terminal.
JP 2002-325115 A

  However, since the conventional information terminal device uses a touch sensor, the presence of an unanswered incoming call cannot be known unless the mobile phone is touched. If you have a device in your bag or pocket, it is inconvenient if you have to open your bag and search for the device.

  Moreover, since it does not respond if it does not touch a sensor part, it is inconvenient depending on the position of a sensor part. For example, in the case of a foldable terminal, when the sensor unit is inside the fold, it is inconvenient to touch the sensor unit only after the terminal is opened.

  On the other hand, if it is on the outside or the surface of the terminal, the sensor reacts in a bag or pocket, and there is a possibility of malfunction. If the sensor reacts due to malfunction, power consumption is wasted. Although there is a merit that the user will notice an incoming call due to the sensor reacting due to a malfunction, the user does not operate immediately after noticing, and it does not always operate from an unanswered state to a known state. It is undesirable for the sensor to react.

  In addition, when wearing gloves, the touch sensor is difficult to detect, and a malfunction that the sensor does not react may occur. It is inconvenient to have to take off gloves one by one.

  Therefore, an object of the present invention is to provide an information terminal device that can confirm whether there is an incoming call without malfunction without touching the information terminal device directly.

In order to solve the above problems, an information terminal device according to the present invention provides:
The device body;
An acceleration sensor for detecting the acceleration of the device body;
Based on the acceleration detected by the acceleration sensor, a sensor response determination unit that determines whether or not the device body has undergone sudden shaking;
And a control unit that controls the apparatus main body to a predetermined state when it is determined by the sensor response determining section that the apparatus main body has undergone sudden shaking.

  Here, in this specification, the “predetermined state” means, for example, when the information terminal device is a mobile phone, responding to the incoming call status or converting to the manner mode during the incoming call. When the device is a personal computer, it means backing up data or automatically transmitting information to another terminal.

  According to the information terminal device of the present invention, the acceleration sensor detects the acceleration of the device main body, and the sensor response determination unit suddenly detects the device main body based on the acceleration detected by the acceleration sensor. It is determined whether or not the device has been shaken, and the control unit controls the device body to a predetermined state when the sensor response determination unit determines that the device body has been suddenly shaken. By using the acceleration sensor, the apparatus main body can be controlled to a predetermined state without directly touching the apparatus main body.

  For example, when the information terminal device is a mobile phone, confirmation of an unanswered incoming call and ringing of a ringing tone during an incoming call can be controlled without touching the mobile phone. Therefore, even if the mobile phone is put in a bag or pocket, it can be confirmed or controlled by giving vibration such as shaking the bag or hitting from the top of the pocket without taking it out.

  Further, since the acceleration sensor is used instead of the touch sensor, inconvenience or malfunction does not occur depending on the position of the acceleration sensor with respect to the apparatus main body.

  In addition, by performing control only when a sudden shake is detected, vibrations that occur while riding trains and vibrations caused by vibrations can be canceled as steady shakes, and malfunctions of the control unit can be canceled. Occurrence can be suppressed.

Moreover, in the information terminal device of one embodiment,
The sensor response determination unit determines an acceleration intensity level at regular intervals of time based on the acceleration detected by the acceleration sensor,
When the intensity level of one interval is larger than the intensity level of the interval before and after this one interval, and the intensity levels of the intervals before and after this one interval are the same, the apparatus body suddenly breaks down in the one interval Judged to have been shaken.

  According to the information terminal device of this embodiment, the sensor response determination unit is configured such that the intensity level of the one interval is greater than the intensity level of the interval before and after this one interval, and the intensity level of the interval before and after this one interval. Are equal to each other, it is determined that the apparatus main body has suddenly swayed in the one interval, so that the malfunction of the control unit can be reliably suppressed.

Moreover, in the information terminal device of one embodiment,
The sensor response determination unit determines an acceleration intensity level at regular intervals of time based on the acceleration detected by the acceleration sensor,
When the intensity level of one interval is the same as the intensity level of the interval before and after this one interval, it is determined that the apparatus main body has received a steady fluctuation rather than a sudden fluctuation at the one interval. .

  According to the information terminal device of this embodiment, the sensor response determination unit, when the intensity level of the one interval is the same as the intensity level of the interval before and after the one interval, Since it is determined that the apparatus main body has been subjected to steady shaking instead of sudden shaking, it is possible to reliably suppress the occurrence of malfunction of the control unit.

  Further, in the information terminal device according to an embodiment, the sensor response determination unit performs linear prediction analysis of an acceleration waveform based on the acceleration detected by the acceleration sensor, and based on the linear prediction analysis, the device main body Judge whether or not you have suddenly shaken.

  According to the information terminal device of this embodiment, the sensor response determination unit performs linear prediction analysis of the acceleration waveform based on the acceleration detected by the acceleration sensor, and the device main body is based on the linear prediction analysis. Since it is determined whether or not sudden vibration has occurred, it is possible to reliably suppress the occurrence of malfunction of the control unit.

Moreover, in the information terminal device of one embodiment,
It has a response part that informs the outside of the presence of unanswered incoming calls,
The control unit controls the response unit when there is an unanswered incoming call, and the sensor response judging unit determines that the apparatus main body is suddenly shaken, and an unanswered incoming call is received. Inform outside of existence.

  Here, in this specification, the “unanswered incoming call” refers to an incoming call that the user has left without responding to various incoming calls from the server or the terminal. For example, i) an incoming call that was missed because it did not answer a call, ii) an incoming call that had an answering machine recorded on the terminal at the time of a missed call, or iii) an answering machine recorded or mailed to the server If stored, there was an incoming information from the server such as notifying the terminal from the server, or iv) incoming information such as mail, various contents, or emergency information, but the incoming information remains unconfirmed Information received or v) Information received from the server when there is an incoming notification notifying the completion of download when downloading data from the server to the terminal, but there is no operation on the downloaded data such as checking the downloaded data on the terminal . Also, the response unit generates, for example, a warning signal to notify the outside of the presence of an unanswered incoming call.

  According to the information terminal device of this embodiment, when there is an unanswered incoming call, the control unit controls the response unit to notify the outside of the presence of the unanswered incoming call. Existence becomes clear.

Moreover, in the information terminal device of one embodiment,
A sensor control unit for controlling ON / OFF of the acceleration sensor;
The control unit controls the sensor control unit when the apparatus main body is in a specific state.

  Here, in this specification, the “specific state” means, for example, when the information terminal device is a mobile phone, when there is an unanswered incoming call, when the unanswered incoming call is confirmed, State.

  According to the information terminal device of this embodiment, since the control unit controls the sensor control unit when the device main body is in a specific state, the acceleration sensor can be turned on only when necessary, and sensing is performed. It is possible to prevent wasteful consumption of power consumption.

  In one embodiment of the information terminal device, the control unit turns on the acceleration sensor when there is an unanswered incoming call.

  According to the information terminal device of this embodiment, since the control unit turns on the acceleration sensor when there is an unanswered call, the control unit can turn off the acceleration sensor when there is no unanswered call. Thus, wasteful consumption of power consumption can be prevented.

  In one embodiment of the information terminal device, the control unit turns on the acceleration sensor when there is an unanswered incoming call and the characteristics of the unanswered incoming call satisfy a predetermined condition.

  Here, in this specification, the “characteristic of unanswered incoming call” is, for example, a caller, incoming call type, presence / absence of an answering message, and the “predetermined condition” is, for example, set in advance This is the condition.

  According to the information terminal device of this embodiment, the control unit turns on the acceleration sensor when there is an unanswered incoming call and the characteristics of the unanswered incoming call satisfy a predetermined condition. It is possible to know the existence of only a necessary unanswered incoming call.

Moreover, in the information terminal device of one embodiment,
A response unit that informs the outside of the presence of an unanswered incoming call by a predetermined response method;
When the control unit determines that there is an unanswered incoming call, and the sensor response determining unit determines that the device body has undergone a sudden shake, the control unit determines whether the response unit has The predetermined response method is changed, and the presence of an unanswered incoming call is notified by the response unit using the changed predetermined response method.

  Here, the “change in the predetermined response method” means, for example, a change in the number of vibrations or a change in the type of melody.

  According to the information terminal device of this embodiment, when the control unit receives an unanswered incoming call and the sensor response determination unit determines that the device main body has undergone sudden shaking, the control unit does not respond The predetermined response method of the response unit is selected according to the characteristics of the incoming call, and the presence of an unanswered call is notified by the response unit using the selected predetermined response method, so the user confirms on the screen The characteristics of the unanswered incoming call can be determined by the predetermined response method.

In addition, the ringing of the apparatus main body is controlled.

  According to the information terminal device of this embodiment, when the control unit receives an unanswered incoming call and the sensor response determination unit determines that the device body has undergone sudden shaking. In addition, since the ringing of the apparatus main body is controlled, the manner mode can be set by applying vibration during an incoming call. For example, if you forget to switch to the manner mode and the ringtone becomes a ringtone, you can make it easier to use by not immediately ringing the ringtone. Even if a mobile phone is in the pocket, it can be stopped immediately by simply tapping from the top of the pocket without taking it out.

  Further, since steady vibration and sudden fluctuation are determined and controlled, the vibration caused by the vibration can be determined as a steady vibration. For example, even if both the sound and vibration are set for the incoming call, the vibration due to the vibration can be ignored as a steady vibration, and the vibration does not react only with the vibration of the vibration. As a result, it is possible to accurately control ringing during incoming calls.

  Further, in the information terminal device according to an embodiment, when the control unit receives an unanswered incoming call and the sensor response determination unit determines that the device main body has undergone sudden shaking. Then, the apparatus main body shifts from the ringing state to another state.

  According to the information terminal device of this embodiment, when the control unit receives an unanswered incoming call and the sensor response determination unit determines that the device body has undergone sudden shaking. In addition, since the apparatus main body shifts from the ringing state to another state, it is possible to shift from the ringing state to another state by applying vibration during an incoming call.

  Further, since steady vibration and sudden fluctuation are determined and controlled, the vibration caused by the vibration can be determined as a steady vibration. For example, even if both the sound and vibration are set for the incoming call, the vibration due to the vibration can be ignored as a steady vibration, and the vibration does not react only with the vibration of the vibration. As a result, it is possible to accurately control ringing during incoming calls.

  In addition, the information terminal device according to an embodiment includes a display unit that displays an ON / OFF state of the acceleration sensor.

  According to the information terminal device of this embodiment, since the display unit that displays the ON / OFF state of the acceleration sensor is provided, it can be easily determined whether the acceleration sensor is currently ON or OFF.

Moreover, the control method of the information terminal device of this invention is:

Can do.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 is a block diagram showing an embodiment of the information terminal device of the present invention. The information terminal device includes a device main body 10, an acceleration sensor 1, a sensor reaction acquisition unit 2, a sensor reaction determination unit 3, a sensor control unit 4, a control unit 5, a response unit 6, and a radio unit 7.

  The wireless unit 7 is controlled by the control unit 5 to communicate with the outside. The acceleration sensor 1 detects the acceleration of the apparatus main body 10. The sensor response acquisition unit 2 acquires sensor response information of the acceleration sensor 1 as acceleration data.

  The sensor response determination unit 3 determines whether it is sudden or steady from the acceleration data acquired by the sensor response acquisition unit 2. That is, the sensor response determination unit 3 determines whether or not the apparatus main body 10 has been suddenly shaken based on the acceleration detected by the acceleration sensor 1.

  The control unit 5 controls the device main body 10 to a predetermined state when the sensor response determination unit 3 determines that the device main body 10 has been suddenly shaken. Here, the above-mentioned “predetermined state” is a function specific to the terminal. For example, when the information terminal device is a mobile phone, it means that the incoming call status is answered or converted to the manner mode during the incoming call. When the information terminal device is a personal computer, it means backing up data or automatically transmitting information to another terminal.

  The response unit 6 notifies the presence of an unanswered incoming call to the outside. The control unit 5 controls the response unit 6 when there is an unanswered incoming call and the sensor response determination unit 3 determines that the device main body 10 has been suddenly shaken. Inform the outside that there is an incoming response. The response unit 6 generates a warning signal to inform the outside of the presence of an unanswered incoming call. Note that the response unit 6 may notify the outside of the presence of an unanswered call by a response method other than a warning signal.

  Here, the “unanswered incoming call” refers to an incoming call that the user has left without responding to various incoming calls from the server or terminal. For example, i) an incoming call that was missed because it did not answer a call, ii) an incoming call that had an answering machine recorded on the terminal at the time of a missed call, or iii) an answering machine recorded or mailed to the server If stored, there was an incoming information from the server such as notifying the terminal from the server, or iv) incoming information such as mail, various contents, or emergency information, but the incoming information remains unconfirmed Information received or v) Information received from the server when there is an incoming notification notifying the completion of download when downloading data from the server to the terminal, but there is no operation on the downloaded data such as checking the downloaded data on the terminal .

  The sensor control unit 4 controls ON / OFF of the acceleration sensor 1. The control unit 5 controls the sensor control unit 4 when the apparatus main body 10 is in a specific state. Here, the “specific state” refers to, for example, a state where there is an unanswered incoming call, a state where an unanswered incoming call is confirmed, or a state where an incoming call is received when the information terminal device is a mobile phone.

  For example, the control unit 5 may turn on the acceleration sensor when there is an unanswered incoming call.

  Alternatively, the control unit 5 may turn on the acceleration sensor 1 when there is an unanswered incoming call and the characteristics of the unanswered incoming call satisfy a predetermined condition. Here, the “characteristic of unanswered incoming call” is, for example, a caller, incoming call type, presence / absence of an answering message, and the “predetermined condition” is, for example, a preset condition.

  At this time, the response unit 6 notifies the presence of an unanswered incoming call to the outside by a predetermined response method, and the control unit 5 receives an unanswered incoming call, and the sensor response determination unit 3 causes the device body to respond. When it is determined that 10 is suddenly shaken, the predetermined response method of the response unit 6 is changed according to the characteristics of the unanswered incoming call, and the response unit is changed with the changed predetermined response method. 6 indicates the presence of an unanswered incoming call. Here, the “change in the predetermined response method” means, for example, a change in the number of vibrations or a change in the type of melody.

  The control of the information terminal device is also realized by computer hardware, a program executed by the computer hardware, and data stored in the computer hardware. FIG. 2 shows an internal configuration of the computer system 200.

  As shown in FIG. 2, the computer system 200 includes a computer 220 having an optical disk drive 201 and a magnetic disk drive 202, and a display device 203 such as a monitor.

  In addition to the optical disk drive 201 and the magnetic disk drive 202, the computer 220 is connected to an acceleration sensor 205 that senses external vibration, a CPU (Central Processing Unit) 206, a CPU 206, the optical disk drive 201, and the magnetic disk drive 202. A bus 207, a read-only memory (ROM) 208 connected to the bus 207 and storing a boot-up program and the like, and a random access memory connected to the bus 207 and storing a program command, a system program, work data, and the like (RAM) 209.

  Although not shown here, the computer 220 may further include a network adapter board that provides connection to a local area network (LAN), and a communication device that performs wireless communication.

  A program for causing the computer system 200 to realize the control function of the information terminal device is stored in the optical disk 210 or the magnetic disk 211 inserted into the optical disk drive 201 or the magnetic disk drive 202 and further transferred to the hard disk 212.

  Alternatively, the program may be transmitted to the computer 220 through a network (not shown) and stored in the hard disk 212. The program is loaded into the RAM 209 when executed. The program may be loaded directly into the RAM 209 from the optical disk 210, from the magnetic disk 211, or via a network.

  This program includes a plurality of instructions for causing computer 220 to realize the functions of the information terminal device according to the present embodiment. Some of the basic functions necessary to realize these functions are provided by operating system (OS) or third-party programs running on the computer 220 or modules of various toolkits installed on the computer 220.

  Therefore, this program does not necessarily include all functions necessary for realizing the functions of the information terminal device. If this program contains only the instruction for executing the control of the information terminal device described above by calling an appropriate function or “tool” in a controlled manner so as to obtain a desired result. Good. The operation of computer system 200 is well known and will not be repeated here.

  Recording media on which programs for realizing the functions of the information terminal device are recorded are CD-ROM (Compact Disc Read Only Memory), MO (Magneto-Optical disc), MD (Mini Disc), and DVD (Digital Versatile Disc). The optical disk 210 such as), the FD (flexible disk), and the magnetic disk 211 such as a hard disk. Tapes such as magnetic tape and cassette tape, card-type recording media such as IC (Integrated Circuit) card and optical card, and semiconductors such as mask ROM, EPROM (Erasable Programmable ROM), EEPROM (Electrically Erasable Programmable ROM), and flash ROM It can be either memory. However, the computer system 200 needs to be equipped with a reading device for reading from these recording media.

  In short, the program of the present invention is a program for controlling the information terminal device as shown in FIG. 1, and the acceleration of the device main body 10 is detected by the acceleration sensor 1, and the device main body 10 is suddenly detected. A step of determining by the sensor reaction determination unit 3 based on the acceleration detected by the acceleration sensor 1 and whether the apparatus main body 10 is suddenly shaken by the sensor reaction determination unit 3. A program for causing the computer to execute the step of controlling the apparatus body 10 to the predetermined state by the control unit 5 when it is determined that the control unit 5 has been received. Here, the “computer” refers to an arithmetic processing unit of an information terminal device.

  The recording medium of the present invention is a computer-readable recording medium in which a program for controlling the information terminal device is recorded. The acceleration of the device main body 10 is detected by the acceleration sensor 1, and the device main body 10 is detected. The sensor response determination unit 3 determines whether the device body 10 has suddenly shaken based on the acceleration detected by the acceleration sensor 1 and the sensor response determination unit 3 causes the device body 10 to suddenly The recording medium stores a program for causing a computer to execute the step of controlling the apparatus main body 10 to the predetermined state by the control unit 5 when it is determined that the control unit 5 has received a specific shake.

  Next, a method for controlling the information terminal device will be described.

  In this control method, as shown in FIG. 1, the acceleration of the apparatus main body 10 is detected by the acceleration sensor 1, and whether or not the apparatus main body 10 is suddenly shaken is detected by the acceleration sensor 1. Based on the measured acceleration, when the sensor response determination unit 3 determines that the device main body 10 has undergone sudden shaking, the control unit 5 determines the device. And a step of controlling the main body 10 to the predetermined state.

  Specifically, as shown in FIG. 3, when the sensor of the acceleration sensor is ON, vibration is sensed, and the sensed information is sent to the sensor reaction acquisition unit. The sensor reaction acquisition unit sends the acquired information to the sensor reaction determination unit. The sensor reaction determination unit determines whether the fluctuation is sudden or steady from the obtained acceleration waveform data (step S1). This determination method will be described later.

  And when it is not judged as a sudden fluctuation (process S2), nothing is done. On the other hand, if it is determined that there is a sudden fluctuation (step S2), the presence of an unanswered incoming call is checked, and if it exists, the content of the unanswered incoming call is notified to the user (step S3).

  Here, it may be notified after determining whether to notify the user according to the type of unanswered incoming call. Alternatively, when the acceleration sensor is turned on only when there is a type of unanswered call that needs to be notified to the user, the user is notified of the contents of the unanswered call without checking the presence or type of the unanswered call.

  When it is determined that the sensor response determination unit 3 has received a sudden shake, the response unit 6 is controlled to notify the outside of the presence of an unanswered incoming call. The response unit 6 generates a warning signal to inform the outside of the presence of an unanswered incoming call. Note that the response unit 6 may notify the outside of the presence of an unanswered call by a response method other than a warning signal.

  As an example of the response method, you can notify with the set incoming notification function (melody sound, vibration, light flashing, etc.) or notify the incoming content with a synthesized sound, such as “There is one incoming mail” Good. Also, a notification function for response (melody sound, vibration, light blinking, etc.) may be set in advance and the response may be made.

  Further, the response content at the time of response may be changed according to the caller or the incoming call type and the number of unanswered cases. For example, the number of vibrations, the type of melody, etc. are changed. As a result, the user can determine the caller or the incoming call type.

  Then, after the response, the sensor control unit turns off the acceleration sensor (step S4). When the sensor control unit turns off the sensor, the sensor control unit turns on the sensor again after a predetermined time. This prevents continuous response. Even if the user does not give vibration, even if the sensor response determination unit determines that a sudden shake has occurred and responds, the sensor will be turned off for a while after the response, so it will continue to make erroneous determinations and responses This prevents wasteful consumption of power consumption.

  Next, a case where the sensor control unit controls ON / OFF of the acceleration sensor according to the presence or type of the unanswered incoming call will be described.

  As shown in FIG. 4, normally, the acceleration sensor is in an OFF state, and when an incoming call such as an incoming mail or a telephone call occurs, it is determined whether or not an unanswered call has occurred (step S5). If the user notices an incoming call, makes a call, or confirms the received mail, cancels the unanswered state. On the other hand, if a non-response occurs, the sensor control unit checks the caller of the unanswered incoming call, the incoming call type, etc., and determines whether there is an unanswered incoming call to be answered (step S6).

  That is, the user or the system sets whether to respond in advance according to the incoming call type such as mail incoming call or telephone incoming call, and determines whether to respond according to the set contents. In addition, whether to respond is set according to the sender information such as the name of the sender and the group, and it is determined whether to respond according to the set contents.

  Note that it may be determined whether or not the response should be made based not only on the incoming call type but also on whether or not an answering machine message exists. For example, if the mobile phone is turned off or the reception status of the antenna is bad, even if there is an incoming call, you will not be able to receive the call, and if an answering message is left in the service center, the antenna will be ready for reception after that. The mobile phone may be notified that an answering machine message remains in the service center, but if there is a notification from such a server, it may be determined that a response should be made. Good.

  Thereafter, when it is determined that the incoming call is an unanswered call (step S7), the sensor control unit turns on the acceleration sensor (step S8). On the other hand, when it is determined that the response should not be made (step S7), the acceleration sensor is left off.

  In this way, by controlling the ON / OFF of the acceleration sensor according to the presence or type of an unanswered incoming call, it is possible to prevent the sensor control unit from working and wasting power consumption when there is no need to respond.

  The acceleration sensor ON / OFF control may be performed by the user. In addition, a display unit that displays the ON / OFF state of the acceleration sensor may be provided in the information terminal device, and may be displayed in an easy-to-understand manner to inform the user whether the acceleration sensor is currently ON or OFF. When the sensor control unit switches ON / OFF of the acceleration sensor, the display unit also switches ON / OFF display of the acceleration sensor.

  The control unit 5 receives the unanswered incoming call, and also determines that the device main body 10 is suddenly shaken by the sensor response determination unit 3. You may make it control ringing (by a ringtone or vibration).

  Therefore, when the sensor response determination unit 3 detects a sudden fluctuation during an incoming call, it stops ringing due to an incoming call such as a ringtone or a vibration. This makes it easy to use by not immediately ringing the ringtone if you have forgotten to the manner mode and the ringtone is lost. Even if a mobile phone is in the pocket, it can be stopped immediately by simply tapping from the top of the pocket without taking it out.

  Further, since steady vibration and sudden fluctuation are determined and controlled, the vibration caused by the vibration can be determined as a steady vibration. For example, even if both the sound and vibration are set for the incoming call, the vibration due to the vibration can be ignored as a steady vibration, and the vibration does not react only with the vibration of the vibration. As a result, ringing control during an incoming call can be realized with high accuracy.

  Alternatively, when the control unit 5 receives an unanswered incoming call and the sensor response determination unit 3 determines that the device main body 10 has been suddenly shaken, the device main body 10 May be shifted from the ringing state to another state. Here, the “other state” refers to an answering message recording start state or an automatic response start state.

  That is, not only the ringing is stopped, but the state may be shifted to an answering message recording state or an automatic response start state. As an example of an automatic response, a message for notifying the caller that the call cannot be received is notified, a fixed form mail set in advance is mailed to the caller, or download completion confirmation is performed. Thereby, when an incoming call cannot be dealt with immediately, it is possible to change from a ringing state to another state by simply striking the terminal without taking out the terminal from a pocket or the like.

  Next, two determination methods for determining whether the sensor response determination unit 3 is stationary or sudden will be described.

  In the first determination method, the sensor response determination unit 3 monitors the acceleration value or change amount of the acceleration sensor 1 at regular time intervals as shown in FIG. Levels are divided according to the maximum value or average value of acceleration at regular intervals. If the intensity level of acceleration at a certain time is greater than the intensity level at the previous and subsequent times and the intensity levels at the previous and subsequent times are the same, it is regarded as a sudden fluctuation. At this time, only when the difference in intensity level is equal to or greater than a predetermined difference may be regarded as a sudden fluctuation. In FIG. 5, a broken line connecting the maximum acceleration values at regular intervals is indicated by a thick dotted line, and the intensity level at regular intervals is determined by this broken line.

  As shown in FIG. 5, the level of the maximum value between the intervals c to d is D, which is larger than the levels between the intervals b to c and the intervals d to e before and after that, and the intervals b to c and d. The level of the maximum value of ~ e is B, which is the same level. In such a case, it is considered that there was a sudden fluctuation between the intervals c to d. Similarly, the intervals a to b, the intervals b to c, and the intervals d to g are determined to be steady fluctuations because no sudden fluctuation is observed.

  In short, the sensor response determination unit 3 determines the intensity level of acceleration at regular intervals of time based on the acceleration detected by the acceleration sensor 1, and the intensity level of one interval is the one interval. When the intensity level is greater than the intensity level of the interval before and after and the intensity levels of the interval before and after are the same, it is determined that the apparatus main body 10 has been suddenly shaken at the one interval.

  In other words, the sensor response determination unit 3 determines the intensity level of acceleration at regular intervals of time based on the acceleration detected by the acceleration sensor 1, and the intensity level of one interval is When it is the same as the intensity level of the interval before and after the interval, it is determined that the apparatus main body 10 has received a steady oscillation, not a sudden oscillation, in the one interval.

  In the second determination method, the sensor response determination unit 3 monitors the acceleration value or the change amount of the acceleration sensor 1 for each time as shown in FIG. The acceleration waveform thus obtained is subjected to prediction analysis by linear prediction analysis. If a characteristic waveform is extracted, it is regarded as a sudden fluctuation.

  Linear predictive analysis is widely used in speech signal processing as a method for extracting features of a waveform, and by this means it is possible to remove stationary components contained in the waveform. For example, a steady component often exists in an acceleration waveform due to a shake of a vehicle or the like, and it can be removed by linear prediction analysis.

  Therefore, it is possible to remove a waveform due to steady fluctuation and extract a characteristic waveform remaining after the removal as a waveform due to sudden fluctuation.

  When the acceleration waveform of FIG. 6 is subjected to linear prediction analysis, a waveform as shown in FIG. 7 is obtained. When a characteristic waveform such as between the intervals c to d appears, it is considered that sudden fluctuation has occurred. Compared with the first determination method, since a stationary component can be removed, it is possible to extract a characteristic waveform independent of the intensity of acceleration.

  In short, the sensor response determination unit 3 performs linear prediction analysis of the acceleration waveform based on the acceleration detected by the acceleration sensor 1, and based on the linear prediction analysis, the apparatus body 10 is subjected to sudden shaking. It is determined whether or not.

  The first and second determination methods of the present invention for judging whether the fluctuation is sudden or steady and identifying whether the fluctuation is caused by the user are more than the method for discriminating whether the fluctuation is caused by the user based on a threshold value. It is valid.

  The method of identifying by a threshold value is a method in which an arbitrary value is set in advance as a threshold value, and if the value indicating the magnitude of acceleration such as an acceleration value or a frequency is larger than the threshold value, it is regarded as a user's fluctuation .

  A portable device such as a mobile phone is expected to constantly sense some acceleration during movement, and it is considered difficult to set an appropriate threshold value. Since the magnitude of acceleration varies greatly depending on each moving means such as when walking and riding, it is difficult to set a threshold value for identifying a user's fluctuation.

  Therefore, there is a possibility that an erroneous determination is made in the method of determining whether or not the fluctuation is effective based on the threshold value. As in the present invention, a method of measuring sudden fluctuations by measuring how much the fluctuations have changed from the degree of normal fluctuations, or by extracting the characteristic waveforms by canceling the normal waveforms, Different accelerations can be taken into account. For example, there is a possibility that a large shake in the shake can be identified, such as a shake caused by a user hitting the terminal during a ride.

  According to the information terminal device having the above-described configuration, the acceleration sensor 1 detects the acceleration of the device main body 10, and the sensor response determination unit 3 determines the device main body based on the acceleration detected by the acceleration sensor 1. 10 determines whether or not the apparatus main body 10 has undergone sudden shaking, and the control unit 5 determines that the apparatus main body 10 has undergone sudden shaking when the sensor response determination unit 3 determines that the apparatus main body 10 has undergone sudden shaking. Since the acceleration sensor 1 is used, the device main body 10 can be controlled to the predetermined state without touching the device main body 10 directly.

  For example, when the information terminal device is a mobile phone, confirmation of an unanswered incoming call and ringing of a ringing tone during an incoming call can be controlled without touching the mobile phone. Therefore, even if the mobile phone is put in a bag or pocket, it can be confirmed or controlled by giving vibration such as shaking the bag or hitting from the top of the pocket without taking it out.

  Further, since the acceleration sensor 1 is used instead of the touch sensor, there is no inconvenience or malfunction due to the position of the acceleration sensor 1 with respect to the apparatus body 10.

  In addition, by performing control only when a sudden shake is detected, vibrations generated while riding a train or the like, and vibrations caused by vibrations can be canceled as steady shakes. Can be suppressed.

Therefore, the acceleration sensor 1 is turned on only when necessary. Therefore, wasteful consumption of power consumption due to sensing can be prevented.

  Further, according to the information terminal device having the above configuration, the control unit 5 turns on the acceleration sensor 1 when there is an unanswered incoming call. Therefore, when there is no unanswered incoming call, the acceleration sensor 1 Can be turned off, and wasteful consumption of power consumption can be prevented.

  Further, according to the information terminal device having the above configuration, the control unit 5 turns on the acceleration sensor 1 when there is an unanswered incoming call and the characteristics of the unanswered incoming call satisfy a predetermined condition. Therefore, it is possible to know the existence of only a necessary unanswered incoming call.

  Further, according to the control method of the information terminal device having the above configuration, the acceleration of the device main body 10 is detected by the acceleration sensor 1, and whether or not the device main body 10 is suddenly shaken is detected by the acceleration sensor 1. Based on the measured acceleration, when the sensor response determination unit 3 determines that the device main body 10 has undergone sudden shaking, the control unit 5 determines that the device main body 10 10, the apparatus main body 10 can be controlled to a predetermined state by using the acceleration sensor 1 without directly touching the apparatus main body 10.

  Further, according to the program for controlling the information terminal device having the above-described configuration, the acceleration sensor 1 detects the acceleration of the device main body 10 and determines whether or not the device main body 10 has undergone sudden shaking.

The sensor response determination unit 3 determines whether or not it has been received based on the acceleration detected by the acceleration sensor 1, and the sensor response determination unit 3 determines that the device body 10 has undergone sudden shaking. Since the program for causing the computer to execute the step of controlling the device main body 10 to a predetermined state by the control unit 5 is recorded, the above-mentioned device main body 10 can be directly touched without touching it. The apparatus main body 10 can be controlled to a predetermined state.

  In addition, this invention is not limited to the above-mentioned embodiment.
