[Embodiment]
FIG. 1 is a front view of a terminal device 10 according to an embodiment of the present invention. The terminal device 10 is a mobile terminal used by a user. The terminal device 10 is a smartphone here. The terminal device 10 is formed in a rectangular parallelepiped shape so that the horizontal direction when viewed from the front is the short direction and the vertical direction is the long direction. The terminal device 10 has a right-handed XYZ orthogonal coordinate system composed of an X axis, a Y axis, and a Z axis. The X axis extends in the right direction from the left of the terminal device 10. The Y axis extends upward from below the terminal device 10. For the Z-axis, a direction toward the outside from the display area 121 provided in front of the terminal device 10 is a positive direction, and the opposite direction is a negative direction. The display area 121 is a rectangular area in which various images are displayed.

  The terminal device 10 performs voice transmission and reception for a call. The terminal device 10 includes a microphone 15 and a speaker 16 on the front. The microphone 15 is a device for inputting transmission voice. The speaker 16 is a device for outputting a received voice.

  When receiving an incoming call, the terminal device 10 first displays the caller's telephone number in the display area 121. At this time, the name of the caller corresponding to the caller's telephone number (hereinafter referred to as “caller name”) is not displayed in the display area 121. The reason is to prevent the sender name from being seen by a third party other than the user. The sender name is, for example, the name of the sender or the information of the affiliation, and is managed by the telephone book function of the terminal device 10. When the terminal device 10 is moved by the user and the movement satisfies a predetermined condition, the terminal device 10 displays the source name in the display area 121. The display process performed when an incoming call is received is hereinafter referred to as “incoming call display process”.

2 and 3 are diagrams showing how the terminal apparatus 10 moves when a call is received. FIG. 2 shows a state in which the terminal device 10 is lifted by the user U. As shown in FIG. 2A, it is assumed that the terminal device 10 receives an incoming call when the terminal device 10 is placed on the desk T. When there is an incoming call, the telephone number of the caller is displayed in the display area 121. The user U who notices this incoming call holds the terminal device 10. Next, as shown in FIG. 2B, the user U lifts the terminal device 10 upward (here, in the direction of the arrow R1). By this lifting, at least the acceleration in the Z-axis direction changes in the terminal device 10. As shown in FIG. 2B, when the terminal apparatus 10 is lifted so that the display area 121 faces upward, the terminal apparatus 10 increases in acceleration in the positive direction of the Z axis and the display area 121 faces downward. When 10 is lifted, acceleration increases in the negative Z-axis direction. Next, as shown in FIG. 2C, the user U looks at the display area 121 with the front of the terminal device 10 facing himself / herself. At this time, it is assumed that the caller name is displayed in the display area 121 by the incoming call display process. The user U performs an operation of responding to an incoming call after confirming the caller name.
Note that “upper” means a direction having at least a component opposite to the direction of gravity, and “lower” means a direction having at least a component in the direction of gravity. Further, even when the terminal device 10 is in a posture different from that of FIG. 2, such as when the terminal device 10 is installed on the holder, the Z-axis direction acceleration acts on the terminal device 10 by lifting.

FIG. 3 shows a state in which the terminal device 10 is slid on the desk T by the user U. As shown in FIG. 3A, it is assumed that an incoming call is received when the terminal device 10 is placed on the desk T. When there is an incoming call, the telephone number of the caller is displayed in the display area 121. The user U who notices the incoming call touches the terminal device 10. Next, as shown in FIG. 3B, the user U slides on the desk T and moves the terminal device 10 in a direction approaching itself (in this case, in the direction of the arrow R <b> 2). Due to this sliding, the terminal device 10 causes a change in acceleration in at least the X-axis direction, the Y-axis direction, or both of these directions. Next, the user U sees the display of the display area 121 as shown in FIG. At this time, it is assumed that the caller name is displayed in the display area 121 by the incoming call display process. After confirming the sender name, the user U lifts the terminal device 10 as shown in FIG. 3D and performs an operation to respond to the incoming call.
In addition, when the terminal device 10 is placed on a surface with no inclination or a surface with little inclination, the terminal device 10 can slide on the surface.

FIG. 4 is a block diagram illustrating a hardware configuration of the terminal device 10.
The terminal device 10 includes a control unit 11, a display unit 12, an operation unit 13, a wireless communication unit 14, a microphone 15, a speaker 16, an acceleration sensor 17, and a storage unit 18.
The control unit 11 is a processor including a CPU (Central Processing Unit) 11A as an arithmetic processing device, a ROM (Read Only Memory) 11B, and a RAM (Random Access Memory) 11C as a work area. CPU11A controls each part of the terminal device 10 by reading the program memorize | stored in ROM11B or the memory | storage part 18 to RAM11C, and running it.

  The display unit 12 displays an image in the display area 121. The display unit 12 includes, for example, a liquid crystal display. The operation unit 13 receives an operation performed by the user. The operation unit 13 includes, for example, a touch screen and a physical button provided so as to overlap the display area 121. The wireless communication unit 14 performs wireless communication by connecting to a network such as a mobile communication network. This wireless communication includes at least communication for a call. The wireless communication unit 14 includes, for example, a wireless communication circuit and an antenna. The microphone 15 converts voice input by the user into a voice signal and supplies the voice signal to the control unit 11. The speaker 16 converts the sound signal supplied from the control unit 11 into sound and outputs the sound.

  The acceleration sensor 17 is a triaxial acceleration sensor that measures acceleration acting on the terminal device 10. The three axes refer to the X axis, the Y axis, and the Z axis. The acceleration sensor 17 samples (that is, measures) acceleration in the X-axis, Y-axis, and Z-axis directions at a predetermined sampling interval. The sampling interval is approximately 66 milliseconds, for example. Hereinafter, the acceleration acting in the positive direction of each axis is represented by a positive value, and the acceleration acting in the negative direction is represented by a negative value.

  The storage unit 18 stores a program executed by the control unit 11 and phone book data 181. The program includes an algorithm for executing an incoming call display process. The storage unit 18 includes, for example, an EEPROM (Electronically Erasable and Programmable ROM) or a flash memory.

FIG. 5 is a diagram showing the configuration of the phone book data 181. As shown in FIG.
The telephone book data 181 is data in which a telephone number and a name corresponding to the telephone number are registered in association with each telephone number. This name is registered by the user as, for example, a name or an organization name. In the example of FIG. 5, the telephone number “090-1111-****” is associated with the name “Ichiro Yamada”, the telephone number “090-2222-****”, and the name “Hiroshi Suzuki”. Are associated with each other.

FIG. 6 is a block diagram illustrating a functional configuration related to display processing at the time of incoming call of the control unit 11 of the terminal device 10.
The control part 11 implement | achieves the function corresponded to the 1st determination process part 111, the 2nd determination process part 112, and the process part 113 by running a program.
The first determination processing unit 111 performs a process for determining whether or not the terminal device 10 has been lifted. The first determination processing unit 111 includes an acquisition unit 1111 and a determination unit 1112.
The acquisition unit 1111 acquires the acceleration in the triaxial direction that has acted on the terminal device 10 from the acceleration sensor 17.

  Based on the acceleration acquired by the acquisition unit 1111, the determination unit 1112 satisfies a predetermined condition for a change in acceleration in the first period and a change in acceleration in the second period including the first period as a part. If it is determined that the terminal device 10 has been lifted. Specifically, the predetermined condition indicates that the magnitude of the acceleration change in the second period exceeds the second threshold when the magnitude of the acceleration change in the first period is less than the first threshold. .

The second determination processing unit 112 performs processing for determining whether the terminal device 10 has slid on the surface. The second determination processing unit 112 includes a first acquisition unit 1121, a second acquisition unit 1122, and a determination unit 1123.
The first acquisition unit 1121 acquires the inclination of the terminal device 10 with respect to the horizontal direction. The first acquisition unit 1121 acquires the acceleration in the Z-axis direction from the acceleration sensor 17 as a physical quantity indicating this inclination. When the terminal device 10 is placed on a complete horizontal plane, theoretically, the absolute value of acceleration in the Z-axis direction indicates the magnitude of gravity acceleration (9.8 m / s ² ). The absolute value of the acceleration in the Z-axis direction decreases as the inclination of the terminal device 10 with respect to the horizontal direction increases.

  The second acquisition unit 1122 acquires acceleration in a direction having a horizontal component that acts on the terminal device 10. Specifically, the second acquisition unit 1122 acquires the acceleration in the X-axis direction and the acceleration in the Y-axis direction from the acceleration sensor 17.

  Based on the inclination acquired by the first acquisition unit 1121 and the acceleration acquired by the second acquisition unit 1122, the determination unit 1123 determines the horizontal component when the inclination of the terminal device 10 is less than the first threshold. It is determined that the terminal device 10 has slid when the magnitude of the acceleration in the direction in which the terminal device 10 has reached becomes the second threshold value or more.

  The processing unit 113 performs predetermined processing when the determination unit 1112 determines that the terminal device 10 is lifted or when the determination unit 1123 determines that the terminal device 10 has slid. Here, the predetermined process refers to a process of displaying a caller name in the incoming call display process. When receiving an incoming call via the wireless communication unit 14, the processing unit 113 first displays the telephone number of the caller. When it is determined that the terminal device 10 is lifted or the terminal device 10 is slid, the processing unit 113 displays a transmission source name associated with the telephone number of the transmission source in the phone book data 181 in the display area. 121 is displayed.

FIG. 7 is a flowchart showing the flow of the incoming call display process performed by the terminal device 10. The terminal device 10 repeatedly executes the processing steps shown in FIG. 7 at predetermined intervals.
First, the control unit 11 of the terminal apparatus 10 determines whether or not an incoming call has been accepted via the wireless communication unit 14 (step S1). When it is determined that the incoming call is not received (step S1; NO), the control unit 11 ends the process of FIG. When it is determined that the incoming call has been received (step S1; YES), the control unit 11 controls the display unit 12 to display the telephone number of the caller in the display area 121 (step S2). When the transmission source number is “090-1111-xxxx”, “090-1111-xxxx” is displayed in the display area 121 as shown in FIG. In step S2, the sender name is not displayed.

  Next, the control unit 11 performs processing for determining whether or not the terminal device 10 is lifted during the period in which an incoming call is received (processing in steps S3 to S6, which will be described later), and slide of the terminal device 10 A process for determining the presence / absence (the process of steps S7 to S11 described later) is executed in parallel. These processes are repeatedly executed at the same interval as the acceleration sampling interval of the acceleration sensor 17, for example.

<Processing for determining whether the terminal device 10 is lifted>
First, a process for determining whether or not the terminal device 10 is lifted will be described.
FIG. 8 is a timing chart showing temporal changes in acceleration acting on the terminal device 10. FIG. 8 shows temporal changes in the acceleration AX in the X-axis direction, the acceleration AY in the Y-axis direction, and the acceleration AZ in the Z-axis direction as the acceleration acting on the terminal device 10. “O” (white circles) shown in FIG. 8 and other drawings indicate the time at which acceleration is sampled. ΔVa1 indicates the magnitude (absolute value) of the change in acceleration in the period Tsam (corresponding to the first period of the present invention) with the time of each sampling as a reference. Here, the period Tsam corresponds to one sampling period. The threshold value Th1 is a threshold value for ΔVa1, and is an example of the first threshold value of the present invention. ΔVa2 indicates the magnitude (absolute value) of the change in acceleration during the period Tmov (corresponding to the second period of the present invention) with reference to the time of each sampling. The period Tmov is a period longer than at least the period Tsam, and corresponds to three sampling periods here. The threshold value Th2 is a threshold value for ΔVa2, and is an example of the second threshold value of the present invention. The threshold Th1 and the threshold Th2 are set at the design stage or the manufacturing stage according to the model of the terminal device 10.
In the following description, a time from a certain time “T” to i (i is a natural number) before the sampling period is represented as “T−i”, and a time after the i sampling period is represented as “T + i”.

  The controller 11 acquires the triaxial accelerations AX, AY, and AZ sampled by the acceleration sensor 17 (step S3). The control unit 11 stores the acquired accelerations AX, AY, and AZ in the RAM 11C.

Next, the control unit 11 calculates ΔVa1 based on the accelerations AX, AY, and AZ acquired in step S3 (step S4).
FIG. 9A is a diagram illustrating a method for calculating ΔVa1. FIG. 9A shows a method of calculating ΔVa1 based on the acceleration sampled at time Tn shown in FIG.
That is, the control unit 11 obtains the difference between the accelerations AX, AY, AZ sampled at time Tn and the accelerations AX, AY, AZ sampled at time Tn-1, respectively, and calculates the absolute value of the obtained difference, It is calculated as | ΔX1 |, | ΔY1 |, and | ΔZ1 |. Further, the control unit 11 adds | ΔX1 |, | ΔY1 |, and | ΔZ1 | to calculate ΔVa1 (that is, ΔVa1 = | ΔX1 | + | ΔY1 | + | ΔZ1 |). A larger ΔVa1 means that a relatively large change has occurred in the acceleration acting on the terminal device 10 in a very short period (for example, instantaneously) of the period Tsam.

Next, the control unit 11 calculates ΔVa2 based on the accelerations AX, AY, and AZ acquired in step S3 (step S5).
FIG. 9B is a diagram illustrating a method for calculating ΔVa2. FIG. 9B shows a method of calculating ΔVa2 based on the acceleration sampled at time Tn. In this period Tmov, as shown in FIG. 8, it is assumed that the relationship ΔVa1 <Th1 is satisfied.
That is, the control unit 11 determines the maximum and minimum acceleration values for the X axis, the Y axis, and the Z axis based on the accelerations AX, AY, and AZ sampled from the time Tn-3 to the time Tn. Calculate the absolute value of the difference. In the example of FIG. 9B, the absolute value | ΔX2 | of the difference between the acceleration AX sampled at the time Tn and the time Tn−2 is calculated for the X axis. For the Y axis, the absolute value | ΔY2 | of the difference between the accelerations AY sampled at time Tn and time Tn−2 is calculated. For the Z axis, the absolute value | ΔZ2 | of the difference between the acceleration AZ sampled at time Tn and time Tn−1 is calculated. Further, the control unit 11 adds | ΔX2 |, | ΔY2 |, and | ΔZ2 | to calculate ΔVa2 (that is, ΔVa2 = | ΔX2 | + | ΔY2 | + | ΔZ2 |). A larger ΔVa2 means that a relatively large change has occurred in the acceleration acting on the terminal device 10 in a period longer than the period Tsam, which is the period Tmov.

By the way, when ΔVa1 becomes equal to or greater than the threshold Th1 in at least a part of the period Tmov as at time Tm shown in FIG. 8, ΔVa2 is calculated by the calculation method described in FIG. 9C.
That is, the control unit 11 excludes the acceleration sampled before the period in which ΔVa1 is equal to or greater than the threshold Th1 in the period Tmov, and calculates the absolute value of the difference between the maximum value and the minimum value of the acceleration in the period Tmov. To do. In the case illustrated in FIG. 9C, ΔVa1 is equal to or greater than the threshold Th1 at time Tm−2. Therefore, the control unit 11 excludes the acceleration sampled at times Tm-3 and Tm-2, and calculates ΔVa2 based on the acceleration sampled at times Tm−1 and Tm.
Although not shown, at time Tm + 1, the control unit 11 excludes the acceleration sampled at time Tm-2 and calculates ΔVa2 based on the acceleration sampled at times Tm−1, Tm, and Tm + 1. Will be.

  Returning to FIG. 7, the control unit 11 determines whether or not ΔVa2 is equal to or greater than the threshold Th2 (step S6). When it is determined that ΔVa2 is less than the threshold Th2 (step S6; NO), the control unit 11 returns to the process of step S3. In this case, the control unit 11 determines that the terminal device 10 is not lifted.

On the other hand, when it is determined that ΔVa2 is equal to or greater than the threshold Th2 (step S6; YES), the control unit 11 displays the name registered in the phone book data 181 in association with the telephone number of the caller as the caller name. It is displayed in the area 121 (step S12). In the example of FIG. 8, at the time Tp, ΔVa2 increases and becomes equal to or greater than the threshold Th2. Therefore, the control unit 11 displays the sender name in the display area 121 at time Tp. When the transmission source number is “090-1111-xxxx”, the control unit 11 displays “Ichiro Yamada” in the display area 121 as shown in FIG. Thus, the sender name is displayed in the display area 121 by lifting the terminal device 10 described with reference to FIG.
In step S12, the caller name may be displayed instead of the telephone number.

The basis for determining whether or not the terminal device 10 is lifted by the above method will be specifically described.
If a relatively large change in acceleration occurs such that ΔVa2 is greater than or equal to the threshold Th2 in the terminal device 10, the terminal device 10 may have been lifted. However, in all cases where such a change in acceleration occurs, the terminal device 10 is not necessarily lifted. For example, at time Tm-2 shown in FIG. 8 or FIG. 9C, ΔVa1 increases rapidly in a very short period of time Tsam and is equal to or greater than the threshold Th1. The inventor of the present application has obtained the knowledge that this is caused by, for example, the behavior of the component parts of the terminal device 10 when receiving an incoming call or the surrounding environment of the terminal device 10. The inventors of the present application have also confirmed that such a rapid change in acceleration does not always occur at every incoming call. At least a sudden change in acceleration such that ΔVa1 is equal to or greater than the threshold Th1 is different from an acceleration change that occurs when the terminal device 10 is artificially lifted.
In the examples of FIGS. 8 and 9C, abrupt changes occur in the accelerations AY and AZ in the Y-axis and Z-axis directions, but there is a possibility that a sudden change occurs in the acceleration AX in the X-axis direction. There is also.

  For this reason, the control unit 11 defines ΔVa1 to be processed as an abnormal value by the threshold Th1. Then, the control unit 11 calculates ΔVa2 by excluding the acceleration sampled before ΔVa1 is equal to or greater than the threshold value Th1 in the period Tmov. According to this calculation method, at time Tm−2, ΔVa2 is equal to or greater than the threshold Th2, but since ΔVa1 is equal to or greater than the threshold Th1, the control unit 11 does not display the source name. In this case, the control unit 11 regards the value of ΔVa2 calculated at time Tm−2 as an abnormal value, and sets the value of ΔVa2 to zero.

On the other hand, at time Tp, ΔVa1 is less than the threshold value Th1, and ΔVa2 is equal to or greater than the threshold value Th2. In such a case, it is estimated that the terminal device 10 has been lifted artificially because the acceleration change in the terminal device 10 is large to some extent, even though a very short period of rapid acceleration has not occurred. Therefore, the control part 11 displays a sender name.
The threshold value Th2 is set according to the magnitude of the change in acceleration that occurs when the terminal device 10 is artificially moved. The threshold value Th2 is, for example, the magnitude of acceleration that is an abnormal value for each model of the terminal device 10 or the vibration caused by the vibration function so that a change in acceleration due to the activation of the vibration function is not mistaken as lifting the terminal device 10. It is set in consideration of the size and the like. Here, the threshold Th1 and the threshold Th2 satisfy the relationship Th1> Th2.

<Processing for determining presence / absence of slide of terminal device 10>
Next, a process for determining whether or not the terminal device 10 has a slide will be described.
FIG. 10 is a timing chart showing temporal changes in acceleration acting on the terminal device 10. FIG. 10 shows temporal changes in the acceleration AX in the X-axis direction, the acceleration AY in the Y-axis direction, and the acceleration AZ in the Z-axis direction as the acceleration acting on the terminal device 10. “◯” (white circles) shown in FIG. 10 indicates the time at which acceleration is sampled. The threshold values + ThZ and -ThZ are threshold values for the acceleration AZ. | ΔX | is an absolute value of a change in acceleration in the X-axis direction in the period Tsam with respect to each sampling time. Here, the period Tsam corresponds to one sampling period. The threshold value ThX is a threshold value for | ΔX |. | ΔY | is an absolute value of a change in acceleration in the Y-axis direction in the period Tsam with respect to each sampling time. The threshold value ThY is a threshold value for | ΔY |. The threshold values ThX and ThY are set at the design stage or the manufacturing stage according to the model of the terminal device 10.

  The control unit 11 acquires the acceleration AZ in the Z-axis direction sampled by the acceleration sensor 17 (step S7). The control unit 11 stores the acquired acceleration AZ in the RAM 11C. The acceleration AZ is used to specify the inclination of the terminal device 10 with respect to the horizontal direction.

  The controller 11 acquires the accelerations AX and AY sampled by the acceleration sensor 17 (step S8). The control unit 11 stores the acquired accelerations AX and AY in the RAM 11C. The accelerations AX and AY are used to detect movement of the terminal device 10 due to sliding in a direction having a horizontal component.

  Next, the control unit 11 determines whether or not the acceleration AZ acquired in step S7 is greater than or equal to a threshold value + ThZ or less than -ThZ (step S9). That is, the control unit 11 determines whether or not | AZ | ≧ | ThZ | When the relationship | AZ | ≧ | ThZ | is satisfied, the inclination of the terminal device 10 is less than the threshold, and the terminal device 10 is in a posture that can be regarded as a horizontal state. The posture that can be regarded as a horizontal state refers to a posture when the terminal device 10 is placed on a complete horizontal surface, or a posture when the terminal device 10 is placed on a surface with a small inclination that can be regarded as a substantially horizontal surface.

  When it determines with "NO" at step S9, the control part 11 returns to the process of step S7. In this case, the control unit 11 determines that the terminal device 10 is not sliding. In the example of FIG. 10, the acceleration AZ is substantially zero during the period up to the time “Tr” on the time axis. In this case, since the terminal apparatus 10 is not in a posture that can be regarded as a horizontal state, it is determined that the terminal apparatus 10 is not moved by sliding as described with reference to FIG. Therefore, at time Tq in FIG. 10, | ΔX | is equal to or greater than the threshold ThX, but it is not determined that the terminal device 10 has slid.

  On the other hand, after time Tr, since the acceleration AZ is equal to or greater than the threshold value + ThZ, the control unit 11 determines “YES” in step S9. In this case, the control unit 11 calculates | ΔX | and | ΔY |, which are magnitudes of changes in acceleration from the period Tsam before, for the accelerations AX and AY acquired in step S7 (step S10). Here, the control unit 11 calculates the absolute value | ΔX | of the change in acceleration in the X-axis direction and the absolute value | ΔY | of the change in acceleration in the Y-axis direction by the same method as the calculation method described in FIG. 9A. Each will be calculated.

Next, the control unit 11 determines whether | ΔX | is equal to or greater than the threshold ThX or whether | ΔY | is equal to or greater than the threshold ThY (step S11).
For example, at time Ts, | ΔX | and | ΔY | increase, but are less than the threshold values ThX and ThY, respectively. Therefore, the control unit 11 determines “NO” in Step S11. In this case, the control unit 11 determines that the terminal device 10 is not sliding. In this case, the control part 11 returns to the process of step S7.

  On the other hand, at time Tt, | ΔY | increases and is equal to or greater than the threshold ThY. Therefore, the control unit 11 determines “YES” in Step S11. Then, the control unit 11 displays the name registered in the phone book data 181 in association with the telephone number of the caller in the display area 121 as the caller name (step S12). When the transmission source number is “090-1111-xxxx”, the control unit 11 displays “Ichiro Yamada” in the display area 121 as shown in FIG. Accordingly, the sender name is displayed in the display area 121 by the sliding of the terminal device 10 as described with reference to FIG.

  According to the embodiment described above, when the terminal device 10 receives an incoming call, the terminal device 10 determines that the terminal device 10 has been lifted or moved by sliding based on the change in acceleration applied to the terminal device 10. If you do, the sender name is displayed. The determination of whether or not the terminal device 10 is lifted is performed based on the sampling result of the acceleration in the period Tmov corresponding to the three sampling periods, and the determination of the presence or absence of the slide of the terminal apparatus 10 is performed based on the acceleration in the period Tsam corresponding to one sampling period. Since it is performed based on the sampling result, an increase in processing time required for these determinations can be suppressed. As a result, the display delay of the sender name in the terminal device 10 is suppressed. The terminal device 10 also displays the name of the caller when it is determined that there has been movement due to sliding on the surface. For this reason, even before the terminal device 10 is actually held by the user as described with reference to FIG.

  Further, in determining whether or not the terminal device 10 is lifted, even when the acceleration change during the period Tmov is large, the acceleration at the time when the acceleration change during the period Tsam is large is excluded as an abnormal value. For this reason, generation | occurrence | production of the malfunction that it is determined with the lifting of the terminal device 10 based on the change of the acceleration other than the lifting of the terminal device 10 is suppressed.

  Further, the determination that the terminal device 10 has slid is based on the condition that acceleration in a direction having a component in the horizontal direction is applied when the terminal device 10 is in a posture that can be regarded as a horizontal state. For this reason, compared with the case where the attitude | position of the terminal device 10 is not considered, possibility that a sender name will be displayed at an incorrect timing becomes low.

[Modification]
The present invention may be implemented in a form different from the above-described embodiment. Moreover, you may combine each of the modification shown below.
(Modification 1)
Regarding the determination of whether or not the terminal device is lifted, the terminal device may change one or both of the length of the period Tmov and the threshold Th2.

FIG. 12 is a block diagram illustrating a functional configuration related to the incoming call display process of the control unit 11 of the terminal device 10A according to this modification. The control unit 11 implements functions corresponding to the first determination processing unit 111A, the second determination processing unit 112, and the processing unit 113 by executing a program. The second determination processing unit 112 and the processing unit 113 have the same functional configuration as the above-described embodiment.
111 A of 1st determination process parts implement | achieve the function corresponded to the 1st setting part 1113 and the 2nd setting part 1114 in addition to the acquisition part 1111 and the determination part 1112. The first setting unit 1113 sets the length of the period Tmov while changing the length of the period Tmov. The second setting unit 1114 sets the threshold value Th2 while changing the threshold value Th2.

FIG. 13 is a flowchart showing the flow of the incoming call display process performed by the terminal device 10A. The control unit 11 of the terminal device 10A sets the length of the period Tmov at an arbitrary timing before receiving a call (step S21), and further sets a threshold Th2 (step S22). For example, the control unit 11 sets the length of the period Tmov specified by the user or the threshold value Th <b> 2 according to the operation of the operation unit 13.
Thereafter, the control unit 11 executes the processes of steps S1 to S12 according to the settings of steps S21 and S22.

FIG. 14 is an explanatory diagram of a method of calculating a change in acceleration during the period Tmov in step S5. FIG. 14 shows a method of calculating ΔVa2 when the acceleration sampled at time Tk is acquired and the period Tmov is set to 5 sampling periods.
As can be seen from FIG. 14, | ΔX2 |, | ΔY2 |, | ΔZ2 |, which are absolute values of the difference between the maximum value and the minimum value of the acceleration in the period from time Tk-5 to time Tk, are expressed as time Tk-3. To the absolute value of the difference between the maximum value and the minimum value of the acceleration in the period from the time Tk to the time Tk, or should be larger than that. That is, ΔVa2 tends to increase as the period Tmov increases. For this reason, even if the terminal device 10A moves slowly or smallly, the control unit 11 can easily determine that the terminal device 10A is lifted (that is, the sensitivity increases). On the other hand, as the period Tmov is shortened, the control unit 11 does not determine that the terminal device 10A has been lifted (that is, the sensitivity decreases) unless the terminal device 10A moves rapidly or significantly. Further, as the period Tmov is shortened, the time required to calculate ΔVa2 is shortened, so that the immediate response of the terminal device 10A is improved.
Therefore, the user of the terminal device 10A may adjust one or both of the threshold Th2 and the period Tmov so that the sensitivity is suitable for his / her preference and the usage of the terminal device 10A.

FIG. 15 is a timing chart showing temporal changes in acceleration acting on the terminal device 10A when the threshold value Th2 is set to be smaller than in the case shown in FIG.
As can be seen from FIG. 15, the smaller the threshold Th2, the more likely that ΔVa2 becomes equal to or greater than the threshold Th2 even with a slow or small movement of the terminal device 10A. That is, it becomes easy for the control unit 11 to determine that the terminal device 10A has been lifted (that is, sensitivity is increased). Conversely, as the threshold value Th2 is increased, ΔVa2 does not become equal to or greater than the threshold value Th2 if there is no rapid movement of the terminal device 10A or no significant movement. That is, it becomes difficult for the control unit 11 to determine that the terminal device 10A has been lifted (that is, the sensitivity decreases).
Therefore, the user of the terminal device 10A may set the threshold Th2 so that the sensitivity is suitable for his / her preference and the use of the terminal device 10A. In the example of FIG. 15, since the sender name is displayed at time Tu, the timing is earlier than in the case shown in FIG.
According to this modification, 10 A of terminal devices can determine the presence or absence of the own terminal device with the sensitivity suitable for use of each user, and can display a sender name.

(Modification 2)
Regarding the determination of the presence / absence of the slide of the terminal device, the terminal device may change one or both of the threshold values ThX and ThY.
FIG. 16 is a block diagram showing a functional configuration related to the incoming call display process of the control unit 11 of the terminal device 10B according to this modification. The control part 11 implement | achieves the function corresponded to the 1st determination process part 111, the 2nd determination process part 112B, and the process part 113 by running a program. The first determination processing unit 111 and the processing unit 113 have the same functional configuration as the above-described embodiment.
The second determination processing unit 112B implements a function corresponding to the setting unit 1124 in addition to the first acquisition unit 1121, the second acquisition unit 1122, and the determination unit 1123. The setting unit 1124 sets one of the threshold values ThX and ThY, or both, and sets the threshold values ThX and ThY.

FIG. 17 is a flowchart showing the flow of the incoming call display process performed by the terminal device 10B. The control unit 11 of the terminal device 10B sets the threshold values ThX and ThY at an arbitrary timing before accepting an incoming call (step S31). For example, the control unit 11 sets the thresholds ThX and ThY specified by the user in accordance with the operation of the operation unit 13.
Thereafter, the control unit 11 executes the processes of steps S1 to S12 according to the setting of step S31.

FIG. 18 is a timing chart showing temporal changes in acceleration acting on the terminal device 10B when the threshold values ThX and ThY are made smaller than in the case shown in FIG. As can be seen from FIG. 18, as the threshold values ThX and ThY are reduced, | ΔX | and | ΔY | are more likely to be greater than or equal to the threshold values ThX and ThY even with a slow or small movement of the terminal device 10B. That is, the control unit 11 can easily determine that the terminal device 10B has slid (that is, sensitivity is increased). On the other hand, as the threshold values ThX and ThY are increased, | ΔX | and | ΔY | are not equal to or greater than the threshold values ThX and ThY unless there is a sudden movement or a large movement. That is, it becomes difficult for the control unit 11 to determine that the terminal device 10B has slid (that is, the sensitivity decreases). Therefore, the user of the terminal device 10B may set the threshold Th2 so that the sensitivity is suitable for his / her preference and the use of the terminal device 10B. In the example of FIG. 18, the sender name is displayed at time Ts.
According to this modified example, the terminal device 10B can display the sender name with a sensitivity suitable for the use of each user.

(Modification 3)
The terminal device may change the incoming call display process according to the direction in which the display area faces.
FIG. 19 is a flowchart showing the flow of the incoming call display process performed by the terminal device 10C according to this modification. FIG. 20 is a diagram for explaining an incoming call display process performed by the terminal device 10C.
When it is determined that the incoming call has been received via the wireless communication unit 14 (step S1; YES), the control unit 11 of the terminal device 10C acquires the acceleration AZ in the Z-axis direction from the acceleration sensor 17 (step S41). ). Next, the control unit 11 determines whether or not the terminal device 10C is face down (step S42). The terminal device 10C facing backward means a posture in which the terminal device 10C can be regarded as a horizontal state, and a posture in which the display area 121 faces downward. If it is determined as “NO” in step S42, that is, if the terminal device 10C is not face down (for example, face up), the control unit 11 performs the processes of steps S2 to S12 in the same procedure as in the above-described embodiment. Display phone number and caller name. The term “terminal device 10C is face up” refers to a posture in which the terminal device 10C can be regarded as a horizontal state and the display region 121 faces upward. The state in which the terminal device 10C is face up is an example of a state in which the display area 121 faces in a direction that is visible from the outside. In this case, the display area 121 is facing in a direction that is visible from the position of the user or a third party. Therefore, as shown in FIG. 20A, the control unit 11 displays the caller name when the terminal device 10C is lifted or slides after the caller phone number is displayed.
Note that the state in which the display area 121 faces in a direction that can be viewed from the outside is a concept that includes a state in which the display area 121 is not completely visible from the outside, or a state that can be regarded as visible.

  On the other hand, when the control unit 11 determines that the terminal device 10C is face down (step S42; YES), the control unit 11 proceeds to step S12 and displays the source name. That is, as shown in FIG. 20B, the control unit 11 displays the sender name even if the terminal device 10C is not lifted or slides. When the terminal device 10C is face down, the display area 121 is facing in a direction that is not visible from the outside. For this reason, even if the sender name is displayed in the display area 121 immediately after an incoming call, it is unlikely that it will be seen by a third party.

  When it is determined that the terminal device 10C is face down (step S42; YES), the control unit 11 may stop displaying an image on the display unit 12 as illustrated in FIG. If the control unit 11 determines that the terminal device 10 </ b> C has been lifted or slid, the control unit 11 may display the source name in the display area 121. In this case, the power consumption of the terminal device 10C is reduced by the amount that the display on the display unit 12 is not performed when the terminal device 10C is face down.

(Modification 4)
The terminal device may change the process related to the display of the caller name according to the magnitude or direction of the acceleration applied when the terminal device slides. FIG. 21 and FIG. 22 are diagrams for explaining an incoming call display process performed by the terminal device 10D according to this modification.
For example, when | ΔX | or | ΔY | is equal to or greater than the threshold value, the terminal device 10D displays a telephone number and a source name as shown in FIG. On the other hand, when both | ΔX | and | ΔY | are less than the threshold, the terminal device 10D keeps the display of the telephone number as shown in FIG.

  Further, for example, when acceleration is applied in the X-axis direction, the terminal device 10D displays a telephone number and a caller name as shown in FIG. On the other hand, when acceleration in the Y-axis direction other than the X-axis direction is applied, for example, the terminal device 10D keeps the display of the telephone number as shown in FIG.

According to the terminal device 10D of this modified example, only the user who knows the slide condition for starting the display of the sender name displays the sender name by sliding the terminal device 10D by the method. It can also be started. The configuration of this modification may be applied to a process of displaying a sender name when the terminal device 10D is lifted.
Note that the acceleration direction and magnitude conditions described in this modification are merely examples. For example, the terminal device 10D may further subdivide the direction and magnitude of acceleration and perform a plurality of processes according to the direction and magnitude of acceleration.

(Modification 5)
The incoming call display process may be a display process when a message is received, such as an electronic mail or SNS (Social Networking Service). The incoming call display process in this case can be explained by replacing the telephone number of the caller in the above-described embodiment with a character string such as the e-mail address or ID of the caller.

Moreover, in this invention, you may perform processes other than a display process at the time of an incoming call as a process when a terminal device is lifted or slid.
For example, when the terminal device 10 accepts an incoming call, the terminal device 10 outputs a ring tone through the speaker 16. When the terminal device 10 is lifted, the terminal device 10 stops the ringtone or lowers the volume. Thereby, while allowing the user to recognize the incoming call to the terminal device 10, the possibility of causing trouble due to the output of the ringtone to a third party other than the user is reduced. In addition, the terminal device 10 may activate the vibration function when receiving an incoming call, and stop the vibration function when the terminal device 10 is lifted.

  Furthermore, when receiving an incoming call, the terminal device 10 outputs a ring tone through the speaker 16, and when the terminal device 10 slides, the terminal device 10 stops the ringtone or lowers its volume. Thereby, while allowing the user to recognize the incoming call to the terminal device 10, the possibility of causing trouble due to the output of the ringtone to a third party other than the user is reduced. In addition, the terminal device 10 may activate the vibration function when receiving an incoming call, and stop the vibration function when the terminal device 10 slides.

  Further, when the terminal device 10 determines that the terminal device 10 slides in the mode of reducing power consumption of the terminal device 10 by stopping the display on the display unit 12 or the like, the terminal device 10 may return to the normal mode. Good. Also in this case, the possibility that wasteful power consumption occurs is reduced by returning at a timing other than the timing at which the terminal device 10 is moved by the slide.

(Modification 6)
A part of the configuration or operation described in the above-described embodiment may be omitted. The incoming call display process may be, for example, a process of displaying a sender name in accordance with either lifting or sliding of the terminal device 10.
Regarding the determination of whether or not the terminal device 10 is lifted, the terminal device 10 lifts regardless of the acceleration in the remaining period of the period Tmov when ΔVa1 is equal to or greater than the threshold Th1 at least at some time in the period Tmov. It may be determined that the movement is not performed.
The period Tsam is not limited to one sampling period, and may be longer than one sampling period, for example. The period Tmov is not limited to three sampling periods, and may be shorter than, for example, three sampling periods or longer than three sampling periods.
Further, a relationship of Th1 ≦ Th2 may be used.

  Moreover, the order of the processes performed by the terminal device 10 described in the above-described embodiment may be changed. For example, the order of the process of step S8 and the process of step S9 may be reversed. In this case, when the control unit 11 acquires the acceleration AZ in step S7, whether the acceleration AZ is greater than or equal to a threshold value + ThZ or less than -ThZ (that is, whether | AZ | ≧ | ThZ |). ) Is determined (step S9). When it determines with "YES" at step S9, the control part 11 acquires acceleration AX, AY (step S8), and performs the process of step S10, S11. On the other hand, if “NO” is determined in the step S9, the control unit 11 returns to the process of the step S7 without proceeding to the step S8, that is, without acquiring the accelerations AX and AY. In this case, since unnecessary sampling of the accelerations AX and AY is not performed, an effect of improving the processing speed of the control unit 11 can be expected.

The hardware configuration of the terminal device 10 is not limited to the configuration described in the above-described embodiment. The terminal device 10 may have any hardware configuration as long as the required function can be realized.
For example, the inclination of the terminal device 10 with respect to the horizontal direction may be measured by a sensor other than an acceleration sensor such as a gyro sensor. The terminal device 10 may be a terminal device other than a smartphone, such as a feature phone or a tablet computer. Further, the coordinate system including the X axis, the Y axis, and the Z axis in the terminal device 10 is not limited to the coordinate system described with reference to FIG. Further, the direction and number in which the acceleration sensor 17 measures acceleration is not limited to the example described in the above-described embodiment.

  The function realized by the control unit 11 of the terminal device 10 according to the above-described embodiment may be realized by a combination of a plurality of programs, or may be realized by linking a plurality of hardware resources. When the function of the control unit 11 is realized using a program, the program includes a magnetic recording medium (magnetic tape, magnetic disk (HDD (Hard Disk Drive), FD (Flexible Disk)), etc.), optical recording medium (optical disk). Etc.), may be provided in a state stored in a computer-readable recording medium such as a magneto-optical recording medium or a semiconductor memory, or distributed via a network. The present invention can also be understood as a method for controlling a terminal device.
