Description

  The present invention relates to a mobile communication terminal such as a mobile phone that can communicate via a communication network.

  Conventionally, light and sound are generally used as a medium for notification of incoming calls for notifying a user of an incoming voice call or mail in a mobile communication terminal such as a mobile phone. For example, when a voice call or mail is received, an LED or the like is emitted, a preset music or synthesized sound is output, or an incoming notification image is displayed on the display.

  However, depending on the situation where the mobile communication terminal is placed on a desk or the like, there is a case where the incoming notification by the light or the sound cannot be reliably performed.

  FIG. 4 is an explanatory diagram showing coordinates X, Y, and Z defined on the mobile phone 10 and directions of accelerations αX, αY, and αZ detected by the sensor unit 22. The sensor unit 22 can detect the direction of gravity acting on the mobile phone 10 by detecting the acceleration of the mobile phone 10 that occurs in the directions along mutually orthogonal coordinates X, Y, and Z. Each coordinate X, Y, Z is defined by being fixed to the casing of the mobile phone 10. In the example of FIG. 4, the X axis is defined along the width direction (short direction) of the mobile phone 10, and the right direction in the figure is the plus direction. The Y axis is defined along the length direction (longitudinal direction) of the mobile phone 10, and the lower left direction in the figure is the plus direction. The Z coordinate is defined along the thickness direction of the mobile phone 10, and the upward direction in the figure is the plus direction.

This acceleration sensor is mounted on a circuit board (not shown) provided inside the mobile phone 20, and a known sensor that can detect the accelerations αX, αY, αZ can be used. In addition to the triaxial acceleration sensor, the sensor unit 22 may additionally include another sensor such as a geomagnetic sensor so that the posture of the mobile phone 10 can be detected with higher accuracy.

FIGS. 5A to 5C are explanatory views schematically showing an example of the relationship between the tilt of the mobile phone 10 and the output direction of the LED light.
FIG. 5A shows a case where the front surface 10A (see FIG. 3) on which the key operation unit 21 is provided is parallel to a horizontal direction orthogonal to gravity. In this case, the sensor unit 22 outputs a value corresponding to −1 g (g: gravitational acceleration) as an output value of the acceleration αZ in the Z-axis direction. Then, the LED light is output in the direction A facing upward from the front surface 10A to the outside.
FIG. 5B shows a case where the mobile phone is slightly tilted so that the side surface 10E side (see FIG. 3) is on the upper side. In this case, the sensor unit 22 outputs a value corresponding to the acceleration within a range between −1 g and − (sin 45 ° × g) as the output value of the acceleration αZ in the Z-axis direction, and the acceleration in the X-axis direction. As an output value of αX, a value corresponding to an acceleration within a range between 0 g and (sin 45 ° × g) is output. And although it inclines a little from the direction which faced upwards, LED light is output to the direction of A which goes to the outer side from 10 A of front surfaces.
FIG. 5C shows a case where the mobile phone is further tilted so that the side surface 10E is on the upper side. In this case, the sensor unit 22 outputs a value corresponding to the acceleration within the range between 0 g and − (sin 45 ° × g) as the output value of the acceleration αZ in the Z-axis direction, and the acceleration αX in the X-axis direction. As the output value, a value corresponding to an acceleration within a range between 1 g and (sin 45 ° × g) is output. And although it inclines a little from the direction which turned upwards, LED light is output to the E direction which goes outside from the side surface 10E.

  As described above, in the example of FIGS. 5A to 5C, 45 ° is set as the threshold value of the tilt angle of the front surface of the mobile phone 10, and the output of the LED light is set with this threshold value as a boundary. The direction changes. Note that the threshold of the tilt angle is not limited to 45 °. For example, 30 ° and 60 ° may be set as the threshold of the tilt angle. In this case, LED light may be output in both directions A and E when the tilt angle is in the range of 30 ° to 60 °.

  FIG. 6 is an explanatory diagram schematically illustrating an example of the relationship between the values of accelerations αX and αY detected when the mobile phone 10 is further tilted in various directions and the output directions A to F of the LED light. The hatched area in FIG. 6 indicates a case where the front surface 10A or the back surface 10F (see FIG. 3) of the mobile phone 10 is parallel to the horizontal plane or inclined within a range of 45 ° from the horizontal plane. Yes. In this case, the LED light is output in the outward A direction from the front surface 10A or in the outward F direction from the back surface 10F regardless of the acceleration values in the X-axis direction and the Y-axis direction.

  On the other hand, when the front surface 10A or the back surface 10F of the mobile phone 10 is inclined within a range of 45 ° to 90 ° with respect to the horizontal plane, the acceleration αX and αY values in the X axis direction and the Y axis direction are further set. Accordingly, the output direction of the LED light is switched. Specifically, as shown in an annular white area located around the hatched area in FIG. 6, the output direction of the LED light is the B direction, the C direction, and the D direction according to the values of the accelerations αX and αY. And E direction. The possible ranges of the values of the accelerations αX and αY are a range of −1 g to − (sin 45 ° × g) and a range of (sin 45 ° × g) to 1 g.

  Table 1 is a list summarizing the relationship between the output directions A to F of the LED light and the detection value conditions of the sensor unit 22 used for determining the switching. In the example of Table 1, the case where the threshold of the tilt angle is 45 ° is shown, but the threshold of the tilt angle is not limited to 45 ° as described above. For example, 30 ° and 60 ° may be set as the threshold of the tilt angle. Also, as shown in Table 2, LED light is not output from the direction of gravity or the direction closest to that direction, but LED light is output from all or a part of the other five surfaces from the outward direction. May be.

  FIG. 7 is a flowchart showing an example of processing for checking the tilt of the mobile phone based on the conditions shown in Table 1 and selecting the LED light output directions A to F. In this example, the sensor unit 22 detects triaxial accelerations αX, αY, αZ corresponding to the gravitational acceleration acting on the mobile phone 10 (S11). Next, the control unit 13 selects the LED light output directions A to F based on the output values of the accelerations αX, αY, and αZ detected and output by the sensor unit 22 as follows. First, the control unit 13 determines whether or not the output value of the acceleration αZ in the Z-axis direction is within a range R1 defined by −g <αZ <− (sin 45 ° × g) (S12). Here, “g” is a gravitational acceleration. When the output value of the acceleration αZ is in the predetermined range R1 (Yes in S12), it is determined that the surface 10A on which the display unit 20 of the mobile phone 10 is provided is in a normal posture facing upward, and the LED The A direction (front direction) is selected as the light output direction (S13). In the case of No in S12, the control unit 13 further determines whether or not the output value of the acceleration αZ is in a range R2 defined by (sin 45 ° × g) <αZ <1g (S14). Here, when the output value of the acceleration αZ is in the predetermined range R2 (Yes in S14), it is determined that the surface 10A of the mobile phone 10 is in an upside down posture, and the output direction of the LED light is The F direction (back direction) is selected (S15).

  In the case of No in S14, the control unit 13 determines that the mobile phone 10 is inclined obliquely, and selects the LED light output direction based on the output values of the accelerations αX and αY. Specifically, as illustrated in FIG. 7, the control unit 13 determines whether or not the output values of the accelerations αX and αY are in the relationship R3 defined by | αX | ≧ | αY | (S16). . When the output values of the accelerations αX and αY are in the predetermined relationship R3, that is, when the acceleration αX is equal to or higher than the acceleration αY (Yes in S16), the control unit 13 further determines whether the output value of the acceleration αX is a positive value. It is determined whether or not (S17). Here, when the output value of the acceleration αX is positive (Yes in S17), the E direction from the side surface is selected as the output direction of the LED light (S18), and the output value of the acceleration αX is zero or negative (S17). No), the B direction from the side is selected as the output direction of the LED light (S19).

  If No in S16, that is, if the acceleration αX is smaller than the acceleration αY, the control unit 13 further determines whether or not the output value of the acceleration αY is a positive value (S20). Here, when the output value of the acceleration αY is positive (Yes in S20), the direction D from the side surface is selected as the output direction of the LED light (S21), and the output value of the acceleration αY is zero or negative (S20). No), the C direction from the side surface is selected as the output direction of the LED light (S22).

  FIG. 8 is a flowchart showing another example of processing for checking the tilt of the mobile phone based on the conditions shown in Table 2 above and selecting the LED light output directions A to F. In this example, when the output direction is selected for a certain surface, the output direction is also selected for four surfaces adjacent to the surface. For example, as shown in steps S32 and S33 of FIG. 8, when selecting the outward output direction A from the surface 10A, the outward output directions B, C, from the four adjacent surfaces 10B, 10C, 10D, and 10E. D and E are also selected. The process of confirming the tilt of the mobile phone 10 based on the output values of the accelerations αX, αY, αZ detected and output by the sensor unit 22 is the same as the process of FIG. Is omitted.

  7 and 8, the inclination of the mobile phone 10 is confirmed based on the output values of the accelerations αX, αY, αZ output from the sensor unit 22, but the outputs of the accelerations αX, αY, αZ. The tilt angle of the mobile phone 10 may be calculated from the value, and the tilt of the mobile phone 10 may be confirmed based on the calculated angle.

  FIG. 9 and FIG. 10 are flowcharts showing yet another processing example for checking the inclination of the mobile phone 10 based on the calculation result of the inclination angle of the mobile phone and selecting the LED light output directions A to F. In this example, the sensor unit 22 detects biaxial accelerations αX and αY corresponding to the gravitational acceleration acting on the mobile phone 10 (S51). Next, using the output values of the accelerations αX and αY detected and output by the sensor unit 22, the control unit 13 uses the two angles shown in FIG. 4, that is, the gravity direction G and the X-axis direction. And an angle θY between the gravity direction G and the Y-axis direction are calculated (S52).

  Next, the control unit 13 selects the LED light output directions A to F based on these angles θX and θY as follows. First, the control unit 13 determines whether or not the angle θY is within a range R11 defined by 45 ° ≦ θY ≦ 135 ° (S53). Here, when the angle θY is in the predetermined range R11 (Yes in S53), the control unit 13 further determines whether or not the angle θX is in the range R12 defined by 0 ° ≦ θY <45 °. (S54). When the angle θX is within the predetermined range R12 (Yes in S54), the E direction is selected as the LED light output direction (S55). Further, the control unit 13 determines whether or not the angle θX is in a range R13 defined by 45 ° ≦ θY <135 ° (S56). If Yes, the A direction is selected as the LED light output direction. (S57). Further, the control unit 13 determines whether or not the angle θX is within a range R14 defined by 135 ° ≦ θY <225 ° (S58). If Yes, the B direction is selected as the LED light output direction. (S59). Further, the control unit 13 determines whether or not the angle θX is within a range R15 defined by 225 ° ≦ θY <315 ° (S60). If Yes, the F direction is selected as the LED light output direction. (S61). When the angle θX is not in any of the above ranges R12, 13, 14, and 15 (No in S60), the E direction is selected as the LED light output direction (S62).

  In the case of No in S53, as shown in FIG. 10, the control unit 13 determines whether or not the angle θY is in a range R16 defined by 135 ° ≦ θY <225 ° (S71). The C direction is selected as the LED light output direction (S72). Further, the control unit 13 determines whether or not the angle θY is within a range R17 defined by −45 ° ≦ θY <45 ° (S73). If Yes, the D direction is the LED light output direction. Selected (S74). If the angle θY is not in any of the ranges R16 and R17 (No in S73), the F direction is selected as the LED light output direction (S75).

  FIG. 11 is a flowchart showing an operation example when the light emitting unit 16 emits LED light when a trigger event such as an incoming call when a voice call or mail is received or an alarm time arrives in the mobile phone 10 having the above configuration. It is. In this operation example, when the control unit 13 recognizes that an event that triggers an incoming voice call or mail or an alarm occurs (S101), the control unit 13 shows the above-described FIG. 7 to FIG. The process confirms the inclination of the mobile phone 10 and selects the output direction, and selects the light emitting unit 16 that emits light (S102). Next, the control unit 13 controls the selected light emitting unit 16 to output a predetermined LED light set in advance for incoming call notification (S103). Thereby, LED light can be output from the predetermined outer wall surface selected based on the inclination of the mobile phone 10 in response to a trigger event such as an incoming voice call or mail or an alarm (S104).

As mentioned above, according to this embodiment, based on the detection result of the sensor part 22, the output direction of LED light suitable for notification of incoming calls can be selected from a plurality of outer wall surfaces that can output LED light. . By outputting LED light in the direction selected in this way, from the outer wall surface that allows the user to reliably recognize the output regardless of the orientation when the mobile phone 10 is placed on a desk or the like, It is possible to output LED light used for notification that there is an incoming call. Therefore, regardless of the direction when the mobile phone 10 is placed on a desk or the like, the user can be surely recognized that LED light or sound is being output.
Further, according to the present embodiment, based on the detection results of the accelerations αX, αY, αZ of the sensor unit 22, it is adjacent to the upward outer wall surface located on the side opposite to the direction of gravity or the upward outer wall surface thereof. LED light is output in the direction from the lateral outer wall surface toward the outside. Since the direction from the outer wall surface facing upward or the outer wall surface to the outside toward the outside is lower than the direction from the outer wall surface facing downward to the outside, there is a low probability of an obstacle blocking the output of the LED light. It is possible to more reliably recognize the LED light used for notification that there has been an incoming call.

  FIG. 12 shows that a sound such as a synthesized sound is output from the speaker unit 18 when a trigger event occurs such as when an incoming call is received or when an alarm time is reached in the mobile phone 10 according to another embodiment. It is a flowchart which shows the operation example at the time. In this operation example, the speaker unit 18 is provided on each of a plurality of different outer wall surfaces of the mobile phone 10. Then, when the control unit 13 recognizes that an event that triggers an incoming voice call or e-mail or an alarm occurs (S201), the control unit 13 performs the same processing as shown in FIGS. By confirming the inclination of the mobile phone 10, the output direction is selected, and the speaker unit 18 that performs the sound output operation is selected (S202). Next, the control unit 13 controls the selected speaker unit 18 to output a predetermined synthesized sound or the like preset for incoming call notification or alarm notification (S203). Accordingly, a predetermined synthesized sound or the like can be output from a predetermined outer wall surface selected based on the inclination of the mobile phone 10 in response to a trigger event such as an incoming voice call or mail or an alarm occurrence.

  FIG. 13 is a flowchart illustrating an operation example of selecting the display unit 20 that outputs an image such as an incoming call notification image or an alarm notification image when there is a change in posture in the mobile phone 10 of still another embodiment. In this operation example, the display unit 20 is provided on each of a plurality of different outer wall surfaces of the mobile phone 10. When the control unit 13 recognizes that the posture of the mobile phone 10 has changed based on the detection result of the sensor unit 22 (S301), the control unit 13 performs the same processing as shown in FIGS. The inclination of 10 is confirmed, the output direction is selected, and the display unit 20 that performs the image display operation is selected (S302). Next, the control unit 13 controls to output various images such as an incoming call notification image and an alarm notification image from the selected display unit 20 (S303). As a result, various images can be output to the display unit 20 on the predetermined outer wall surface that is selected so that the user can easily visually recognize the mobile phone 10 based on the tilt.

In addition, when the display unit 20 is provided on only one surface (for example, the front surface 10A), the display unit 20 may be ON / OFF controlled according to the inclination of the mobile phone 10. For example, as shown in Table 3, control is performed so that the display of the display unit (display) 20 is turned on only when the display unit 20 of the mobile phone 10 is facing upward. In this case, useless power consumption can be prevented by turning off the display of the display unit 20 when the display unit 20 is in a position that is not visible or difficult to see by the user.

  In the embodiment, the selection of the LED light output direction (selection of the light emitting unit), the selection of the sound output direction (selection of the speaker unit), and the selection of the output direction of the image (selection of the display unit) are performed. Any combination may be controlled.

  14A and 14B show a combination of selection of the LED light output direction (selection of the light emitting unit 16) and selection of the output direction of the image (selection of the display unit 20) in accordance with the change in the attitude of the mobile phone. 2 is a perspective view showing an external appearance of a mobile phone 10 in the case of control. In this example, light emitting units 10A, 16B, 16C,... 16F that output LED light are provided on each surface of the mobile phone 10. In the cellular phone 10, as shown in FIG. 14A, when the front surface on which the display unit 20 is provided is in a normal posture, the display of the display unit 20 is turned on. The light emitting unit 16A on the front surface is selected as the light emitting unit that outputs LED light. Then, when the mobile phone 10 is rotated as indicated by R in the figure and turned upside down as shown in FIG. 14B, the display of the display unit 20 invisible to the user is turned off and LED light is output. As the light emitting unit, the light emitting unit 16F on the back surface thereof is selected.

  In each of the above embodiments, the case of a mobile phone has been described. However, the present invention can also be applied to the case of other mobile communication terminals such as a PHS and a car phone, and similar effects can be obtained.
