  Embodiments of the present invention will be described. In the following embodiments, a cellular phone is applied as the portable information terminal. First, a first embodiment of the present invention will be described. FIG. 1 is a block diagram illustrating a configuration example of a mobile phone according to the present embodiment. As shown in FIG. 1, the mobile phone 1 according to the present embodiment includes an acceleration sensor unit 1011, a control unit 1012, a memory unit 1013, a speaker unit 1014, a vibrator unit 1015, an LED unit 1016, a display unit 1017, an operation unit 1018, a timer. A unit 1019, a wireless unit (not shown), an antenna unit, a microphone, a receiver, and the like are further provided.

  Explaining each part, the acceleration sensor unit 1011 detects a motion acceleration applied in a three-dimensional direction in each of the X, Y, and Z directions, and is a general acceleration sensor using a piezoelectric element or the like. The memory unit 1013 stores a delay time when setting and canceling the acceleration measurement pattern and the manner mode. In the memory unit 1013 of the mobile phone 1 according to the present embodiment, acceleration measurements for three types of “walking”, “stationary”, and “riding on a vehicle” that are used in advance by a general pedometer or the like are used. A pattern is stored. Further, 30 seconds is stored as the switching delay time t1 for turning on the manner mode, and 1 minute 30 seconds is stored as the switching delay time t2 for turning off the manner mode. The speaker unit 1014, the vibrator unit 1015, and the LED unit 1016 each make a ringtone when the mobile phone 1 receives an incoming call, vibrate the vibration element, and emit light from the light emitting element. Notify about incoming calls. A display unit 1017 is a screen such as an LCD on which the owner of the mobile phone 1 browses information, and an operation unit 1018 is an input for setting various functions displayed on the display unit 1017 by the owner of the mobile phone 1. Is a tool. The control unit 1012 controls these units.

  Next, timing for setting and canceling the manner mode based on the acceleration measured by the acceleration sensor unit 1011 will be described. Hereinafter, the function for setting and canceling the manner mode based on the acceleration is referred to as an automatic manner mode function. The automatic manner mode function according to the present embodiment automatically turns the manner mode on or off according to the measurement pattern when the acceleration measured by the acceleration sensor unit 1011 is a predetermined measurement pattern. Here, when a predetermined measurement pattern is measured, the manner mode is not immediately turned ON or OFF, but the manner mode is turned ON or OFF after a predetermined switching delay time determined in accordance with the measurement pattern has elapsed. To do. In the present embodiment, the manner mode is used when the measurement pattern of “stationary” or “riding a vehicle” used in a general pedometer or the like is measured for the switching delay time t1, that is, continuously for 30 seconds. Is turned on, and the manner mode is turned off when the measurement pattern “walking” is continuously measured for the switching delay time t2, that is, 1 minute 30 seconds.

  FIG. 2 shows a temporal relationship between ON / OFF of the manner mode by the automatic manner mode function and the measurement pattern measured from the acceleration sensor unit 1011. First, an operation mode such as a normal mode and a manner mode is set in the mobile phone 1 by the owner of the mobile phone 1. In this state, the automatic manner mode function is set and measurement by the acceleration sensor unit 1011 is started. When the acceleration sensor unit 1011 measures the measurement pattern “still” or “riding the vehicle”, the operation mode such as the normal mode or the manner mode set by the owner is applied as it is. Furthermore, when the measurement pattern of “stationary” or “riding the vehicle” is continuously measured and the switching delay time t1 (30 seconds) elapses, the manner mode is turned on by the automatic manner mode function. That is, when the operation mode set by the owner is the manner mode, the manner mode remains ON, but when the operation mode set by the owner is the normal mode, the manner mode is entered.

  Furthermore, when the measurement by the acceleration sensor unit 1011 is continued and the measured acceleration changes to a measurement pattern of “walking”, the manner mode is not turned off immediately but the manner mode is turned on. When the measurement pattern “walking” is continuously measured even after the switching delay time t2 (1 minute 30 seconds) has elapsed, the manner mode is turned off by the automatic manner mode function. In this embodiment, when the manner mode is turned off by the automatic manner mode function, the normal mode is set as the operation mode in advance. Furthermore, when the acceleration measured by the acceleration sensor unit 1011 changes from the measurement pattern “walking” to the measurement pattern “stationary” or “riding the vehicle”, the measurement pattern is the switching delay time t1, that is, When the measurement is continued for 30 seconds, the manner mode is turned on by the automatic manner mode function. Thereafter, measurement by the acceleration sensor unit 1011 is continued until the owner of the mobile phone 1 cancels the automatic manner mode function, and the manner mode is turned ON / OFF. When the owner cancels the automatic manner mode function, the manner mode ON / OFF state set at the time of cancellation is set in the mobile phone 1 as it is.

  Thus, when the manner mode is turned ON / OFF by the automatic manner mode function, for example, when the owner of the mobile phone 1 is stationary while waiting for a signal by providing the switching delay time t1 and the switching delay time t2. It is possible to prevent the manner mode from being immediately turned off due to the manner mode being immediately turned on or moving to sit on the seat while riding on the vehicle. Here, it is desirable to further set the switching delay time for several seconds to several minutes.

  The switching delay time t2 (1 minute 30 seconds) is set longer than the switching delay time t1 (30 seconds). By setting the switching delay time t1 <switching delay time t2, when the owner of the mobile phone 1 stands still or gets on the vehicle, the manner mode is immediately turned on, but when the manner mode is on. Priority is given to not disturbing the surroundings by turning off the manner mode for the first time when the owner has continued walking sufficiently without turning off the manner mode immediately even when measuring the walking state of the owner. Can be made. In this embodiment, the switching delay time t1 (30 seconds) and the switching delay time t2 (1 minute 30 seconds) are stored in the memory unit 1013 in advance, but the owner of the mobile phone 1 uses the operation unit 1018. The switching delay times t1 and t2 may be set and changed.

  In this embodiment, when the manner mode is turned off by the automatic manner mode function, the normal mode is automatically set as the operation mode. However, the vibrator unit 1015 and the LED unit 1016 function together. Alternatively, a so-called ringing mode may be set. Furthermore, in this embodiment, when the automatic manner mode function is canceled, the manner mode ON / OFF state set at that time is set as it is, but immediately before the automatic manner mode function is set. The operation mode set in the mobile phone 1 may be stored in the memory unit 1013, and the operation mode stored when the automatic manner mode function is canceled may be set. Furthermore, in this embodiment, the switching delay time when the measurement pattern of “stationary” or “riding the vehicle” is measured is set to the same 30 seconds, but “stationary” and “riding the vehicle” are set. Different switching delay times may be set. For example, by setting the switching delay time in the case of “still” to 30 seconds and the switching delay time in the case of “riding the vehicle” to 20 seconds, the manner mode is smoother in the case of “riding the vehicle”. Can be turned on. Here, even when a plurality of switching delay times are set depending on the type of measurement pattern, the relationship between the switching delay time t1 when the manner mode is turned on and the switching delay time t2 when the manner mode is turned on is the switching delay time t1. <Set to be the switching delay time t2.

  An example of the operation flow of the mobile phone 1 according to the present embodiment is shown in FIG. In FIG. 3, first, the owner of the mobile phone 1 uses the operation unit 1018 to display a function list on the display unit 1017 and set the automatic manner mode function (step 101). When the automatic manner mode function is set, the control unit 1012 controls the acceleration sensor unit 1011 to start measuring acceleration (step 102). The control unit 1012 compares the acceleration measurement pattern stored in the memory unit 1013 with the acceleration measured from the acceleration sensor unit 1011, and the measured acceleration is a predetermined measurement pattern, that is, “still” or “vehicle”. It is determined whether or not the measurement pattern coincides with any of the measurement patterns of “boarding” and “walking” (step 103). When a predetermined measurement pattern is measured, the control unit 1012 controls the timer unit 1019 to start measuring time (step 104). If the measured pattern is “walking”, the process proceeds to step 110. On the other hand, when the measured measurement pattern is “still” or “riding the vehicle” (step 105), the control unit 1012 switches the measurement pattern of “still” or “riding the vehicle” to the switching delay. When the time t1 or longer, that is, continuously measured for 30 seconds or longer (step 106), the manner mode is turned on (step 107). Further, the control unit 1012 causes the acceleration sensor unit 1011 to continue measuring acceleration, and when the acceleration changes to a measurement pattern of “walking” (step 108), it controls the timer unit 1019 to start measuring time. (Step 109). When the measurement pattern “walking” is continuously measured for the switching delay time t2 or longer, that is, for 1 minute and 30 seconds or longer (step 110), the control unit 1012 turns the manner mode OFF (step 111). Thereafter, the measurement of acceleration by the acceleration sensor unit 1011 is continued until the owner of the mobile phone 1 cancels the automatic manner mode function, and steps 103 to 110 are repeated.

  As described above, in the present embodiment, since the manner mode ON / OFF by the automatic manner mode function is performed only by the measurement result from the acceleration sensor unit 1011, the measurement result can be used effectively, and the owner of the mobile phone 1 can The automatic manner mode function can be applied without making various settings. Further, even when a predetermined measurement pattern is measured, the manner mode is not immediately turned ON / OFF, and the predetermined measurement pattern is continuously measured when the switching delay time t1 and the switching delay time t2 have elapsed. Since the manner mode is turned on / off, for example, the manner mode is immediately turned on when the user pauses for a short time, such as waiting for a signal, or the manner mode is immediately turned off when the seat is moved during the conference. There is no. Therefore, the manner mode ON / OFF control can be performed with higher accuracy. Furthermore, by setting the switching delay time for turning off the manner mode to be longer than the switching delay time for turning on the manner mode, the manner mode ON is set quickly, but if the manner mode is ON, it is possessed. Since the manner mode is turned off after sufficiently confirming the person's behavioral form, priority can be given to not disturbing the surrounding people.

  A second embodiment will be described. The cellular phone 1 according to the present embodiment is obtained by adding a schedule function to the cellular phone 1 according to the first embodiment. The memory unit 1013 of the mobile phone 1 stores schedule information of the owner of the mobile phone 1. FIG. 4 shows an example in which schedule information is displayed on the display unit 1017. Figure 4 shows the schedule for March 28, 2006: boarding the 10:13 Shinkansen, attending the meeting at 15:00, going to Yurakucho at 18:30, drinking at 19:00 Registered to attend.

  In FIG. 4, there is a display space for setting detailed contents about “19:00 drinking party” below. Here, “19:00 to 21:00”, “drinking party”, and “normal mode (auto manner setting)” are set as detailed contents of the drinking party at 19:00. Here, “normal mode (automatic manner setting)” refers to the automatic manner mode after setting the operation mode of the cellular phone 1 to the normal mode (speaker unit 1014: OFF, vibrator unit 1015 / LED unit 1016: ON). It means that the function is set. Accordingly, from 19:00 to 21:00 on March 28, 2006, the normal mode is set in the mobile phone 1, and then the acceleration sensor unit 1011 is used to measure acceleration, and the automatic manner mode is set based on the acceleration measurement result. Turn ON / OFF. In other words, when the owner is seated at a drinking party, the manner mode is turned on from the normal mode, and when the owner starts walking due to the end of the drinking party, the manner mode is turned off, that is, the normal mode is set. Return.

  On the other hand, for “18:30 Yurakucho”, “normal mode (automatic manner cancellation)” is set between 18:30 and 18:59 as detailed contents not shown. That is, measurement by the acceleration sensor unit 1011 is not performed from 18:30 to 18:59. Accordingly, the automatic manner mode is not turned on even when the owner is stationary for a long time.

  Here, in FIG. 4, “speaker mark + heart mark” in the drinking party column in the center is set to “normal mode (auto manner setting)”, and “speaker mark” in the Yurakucho column is “ "Normal mode (auto manner cancel)" is set. By checking the “speaker mark + heart mark” and “speaker mark” on the schedule screen, the owner of the mobile phone 1 can set or cancel the automatic manner mode function for each schedule without displaying the detailed contents. Can be recognized.

  As described above, the setting / cancellation of the automatic manner mode function can be registered in the schedule. If the owner of the mobile phone 1 wants to set the manner mode flexibly in accordance with his / her behavior, he / she can set the automatic manner mode function together with a desired operation mode in the schedule in advance.

  Next, a third embodiment will be described. In this embodiment, the acceleration measurement result is effectively used by using the acceleration measured by the acceleration sensor unit 1011 in addition to the manner mode ON / OFF. In the mobile phone 1 according to the present embodiment, the memory unit 1013 stores acceleration measurement patterns corresponding to “walking”, “stationary”, “riding a vehicle”, and “running”.

  An example of the operation flow of the mobile phone 1 according to the present embodiment is shown in FIG. In FIG. 6, as in the first embodiment, the owner of the mobile phone 1 first uses the operation unit 1018 to display a function list on the display unit 1017 to set the automatic manner mode function (step 201). When the automatic manner mode function is set, the control unit 1012 controls the acceleration sensor unit 1011 to start measuring acceleration (step 202). The control unit 1012 compares the acceleration measurement pattern stored in the memory unit 1013 with the acceleration measured from the acceleration sensor unit 1011, and the measured acceleration is a predetermined measurement pattern, that is, “still” or “vehicle”. It is determined whether or not the measurement pattern coincides with any of the measurement patterns “on boarding”, “walking”, and “running” (step 203). When a predetermined measurement pattern is measured, the control unit 1012 controls the timer unit 1019 to start measuring time (step 204). If the measured pattern is “walking” or “running”, the process proceeds to step 210. On the other hand, when the measured measurement pattern is “still” or “riding the vehicle” (step 205), the control unit 1012 switches the measurement pattern of “still” or “riding the vehicle” to the switching delay. When the time t1 or longer, that is, 30 seconds or longer continues (step 206), the manner mode is turned on (step 207). Further, the control unit 1012 causes the acceleration sensor unit 1011 to continue measuring acceleration, and when the acceleration changes to a measurement pattern of “walking” or “running” (step 208), the control unit 1012 controls the timer unit 1019 to control the time. Measurement is started (step 209). When the measurement pattern “walking” or “running” continues for more than the switching delay time t2, that is, 1 minute 30 seconds or more (step 210), the control unit 1012 turns the manner mode OFF (step 211).

  In the present embodiment, it is further determined whether the measurement pattern is “walking” or “running” (step 212). If the measurement pattern is “walking”, the process proceeds to step 215, and the volume of the speaker unit 1014 is set to the normal level. When the measurement pattern is “running”, the volume of the speaker unit 1014 is set to a high level (step 213), and the measurement by the acceleration sensor unit 1011 is continued, and when the measurement pattern changes to a measurement pattern other than “running” ( Step 214), the volume of the speaker unit 1014 is set to a normal level (Step 215). Thereafter, the measurement by the acceleration sensor unit 1011 is continued until the owner of the mobile phone 1 cancels the automatic manner mode function, and Steps 203 to 215 are repeated.

  In the present embodiment, when the acceleration measured by the acceleration sensor unit 1011 is a measurement pattern of “walking” or “running”, the manner mode is turned off, and further, “walking” or “running” is determined. In the case of “running”, the volume of the speaker unit 1014 is increased. By using the measurement result of the acceleration measured by the acceleration sensor unit 1011 also for the volume setting of the speaker unit 1014, the measurement result of the acceleration can be used effectively. Here, the measurement result of the acceleration sensor unit 1011 can be applied to other than the sound volume setting. For example, in combination with a clock function, “stationary” or “riding on a vehicle” in the time zone from 0:00 to 6:00 ”Is measured, the sleep mode (speaker unit 1014, vibrator unit 1015, and LED unit 1015 are all OFF) is set, and“ stationary ”or“ riding on a vehicle ”is measured in other time zones. When the pattern is measured, the manner mode (speaker unit 1014 is OFF, vibrator unit 1015 and LED unit 1015 is ON) can be set. By combining the acceleration measurement result with the time function, the mobile phone 1 can be set according to the behavior of the owner.

  A fourth embodiment will be described. In the present embodiment, the volume of the speaker unit 1014 is controlled using the acceleration measurement result measured by the acceleration sensor unit 1011. The mobile phone 1 according to the present embodiment has a normal mode (speaker unit: ON, vibrator unit 1015: OFF, LED unit 1016: OFF) and a sound mode (speaker unit: ON, vibrator) as operation modes for causing the speaker unit 1014 to function. Section 1015: ON, LED section 1016: ON) can be set. In addition, the speaker unit 1014 is controlled in three levels, “high”, “medium”, and “small”. Here, “medium” is a volume set in the mobile phone 1 as a volume normally used by the owner of the mobile phone 1. The memory unit 1013 of the mobile phone 1 stores acceleration measurement patterns corresponding to “still,” “walking,” and “running”. In the present embodiment, the speaker unit 1014 volume “small”, “medium”, and “large” are set in correspondence with the measurement patterns of “still”, “walking”, and “running”, respectively. Further, the memory unit 1013 has a switching delay time t3 (10 seconds) for setting the volume of the speaker unit 1014 to “low” and a switching delay time t4 (20 seconds) for setting the volume to “medium” or “high”. ) Is stored.

  An operation flow of the mobile phone 1 according to the present embodiment will be described with reference to FIG. In FIG. 6, the owner of the mobile phone 1 first uses the operation unit 1018 to set the normal mode or ringing mode as the operation mode for the mobile phone 1 (step 301). When the normal mode or ringing mode is set, the control unit 1012 controls the acceleration sensor unit 1011 to start measuring acceleration (step 302). At this time, the volume of the speaker unit 1014 is set to “medium”. The control unit 1012 compares the acceleration measurement pattern stored in the memory unit 1013 with the acceleration measured from the acceleration sensor unit 1011, and the measured acceleration is a predetermined measurement pattern, that is, “still” or “walking”. It is determined whether or not the measurement pattern matches any of “medium” and “running” (step 303). When a predetermined measurement pattern is measured, the control unit 1012 controls the timer unit 1019 to start measuring time (step 304). If the measured pattern is “walking” or “running”, the process proceeds to step 308. On the other hand, when the measured measurement pattern is “still” (step 305), the control unit 1012 determines that the “still” measurement pattern is continuously measured for the switching delay time t3 or more, that is, continuously for 10 seconds or more. (Step 306), the volume of the speaker unit 1014 is set to "low" (step 307). On the other hand, when the measurement pattern of acceleration measured in step 305 is “walking” or “running”, the control unit 1012 determines that the measurement pattern of “walking” or “running” is the switching delay time t4 or more, That is, when measurement is continued for 20 seconds or more (step 308), when the measurement pattern is “walking” (step 309), the volume of the speaker unit is changed to “medium” (step 310), and the measurement pattern Is “running” (step 309), the volume of the speaker unit is changed to “high” (step 311). Then, the measurement of acceleration by the acceleration sensor unit 1011 is continued, and when the measurement pattern changes (steps 312a, 312b, 312c), the process returns to step 304. Thereafter, steps 304 to 312 are repeated until the owner of the mobile phone 1 sets the manner mode as the operation mode.

  In the present embodiment, by using the measurement result of the acceleration sensor unit 1011 for controlling the volume of the speaker unit 1014, when the owner is “running” and is difficult to hear the sound of the speaker unit 1014, the volume is automatically set to “high”. If the owner is “still” and it is easy to hear the sound of the speaker unit 1014, the volume is automatically set to “low”. Here, even when the predetermined measurement pattern is measured, the volume is not changed immediately, but only when the predetermined measurement pattern is continuously measured when the switching delay time t3 and the switching delay time t4 have elapsed. Since the volume is changed, for example, the volume of the speaker unit 1014 suddenly decreases when standing for a short time, such as waiting for a signal, or the volume of only a part of the conversation is changed by changing the posture when talking in a stationary state. It can avoid becoming large. Furthermore, by setting the switching delay time for increasing the volume longer than the switching delay time for decreasing the volume, the volume can be decreased relatively quickly when stationary, which is annoying to the surroundings. You can give priority to not applying.

  In this embodiment, the switching delay time for increasing the volume is set longer than the switching delay time for decreasing the volume, but the present invention is not limited to this. When the switching delay time for increasing the volume is made shorter than the switching delay time for decreasing the volume, the volume of the speaker unit 1014 increases immediately after the owner starts traveling, and therefore the owner starts the traveling. It is possible to prevent the conversation from becoming difficult to hear and not being aware of the ringtone. In this embodiment, the switching delay time t3 for setting the volume of the speaker unit 1014 to “low” is 10 seconds, and the switching delay time t4 for setting the volume “medium” or “high” is 20 seconds. However, it is not limited to this. For example, the switching delay time when the volume is changed from “large” to “medium”, “large” to “small”, “medium” to “small”, that is, from the currently set volume to 10 seconds, On the other hand, when the volume is changed from “small” to “medium”, “small” to “large”, “medium” to “large”, that is, when the current set volume is increased, the switching delay time is set to 20 seconds. Etc.

  As described above, the cellular phone 1 according to the present invention uses the acceleration measured by the acceleration sensor unit 1011 for the manner mode ON / OFF control and the volume control of the speaker unit 1014. When applied to the automatic manner mode function, the manner mode is automatically turned on when the measurement pattern of "still" or "riding the vehicle" is measured, and the measurement pattern of "walking" or "running" is set. When measuring, the manner mode is automatically turned off. Since the automatic manner mode function operates only with the measurement result of the acceleration sensor unit 1011, the measurement result of acceleration can be used effectively, and the owner of the mobile phone 1 can use the automatic manner mode function without performing various settings. It becomes possible. Here, the manner mode is turned on after the switching delay time t1 elapses, and the manner mode is turned off after the switching delay time t2 elapses, so that the manner mode can be easily turned on / off, for example, when standing still while waiting for a signal or moving a seat during a meeting. It is possible to avoid being turned off. Further, by setting the switching delay time t1 <the switching delay time t2, the manner mode is quickly turned on, but once the manner mode is turned on, the manner mode is not easily turned off. You can give priority to not disturbing others.

  In addition, when the measurement result of the acceleration sensor unit 1011 is applied to the control of the volume of the speaker unit 1014, the volume changes according to the measurement pattern, and when the owner starts running and it becomes difficult to hear the sound, it is automatic. If the owner is stationary and it is easy to hear the sound of the speaker unit 1014, the volume is automatically set to “low”. By utilizing the measurement result of the acceleration sensor unit 1011 also for the volume control of the speaker unit 1014, the measurement result can be used more effectively, and the setting of the mobile phone 1 can be changed to a setting according to the behavior form of the owner. it can. In the above-described embodiments, the cellular phone 1 has been described. However, any device having a timer function that rings a ringtone or an alarm sound can be applied to a PDA or the like.
