Since the acceleration sensor 15 is built in the information processing device 10, the acceleration sensor 15 detects the acceleration in three directions acting on the information processing device 10.

The angular velocity sensor 16 is a known angular velocity sensor, and detects the rotation angle of the information processing device 10 (particularly the display unit 12) around the reference axis.

Further, here, two angular velocity sensors 16 are provided, rotation of the information processing apparatus 10 in the horizontal direction H and the vertical direction V is detected, and the rotation angles of the directions H and V are indicated by the two angular velocity sensors 16.

Next, the reciprocating displacement detection device 30 of the present embodiment applied to the information processing device 10 will be described.

The reciprocating displacement detection device 30 of the present embodiment includes an acceleration sensor 15, two angular velocity sensors 16 and a determination unit 22 (see FIG. 2), and is based on the detection signals HS and VS of each angular velocity sensor 16 in FIG. 3 (A). ), (B), the information as shown in FIG. 4 is determined based on the reciprocating rotation (rotation operation) of the information processing apparatus 10 in the horizontal direction H and the vertical direction V, and based on the detection signal XS of the acceleration sensor 15. The reciprocating movement of the processing device 10 in the X-axis direction is determined (movement operation).

<Determination of reciprocating rotation of the information processing apparatus 10 in the horizontal direction H and the vertical direction V>
Each angular velocity sensor 16 detects the rotation of the information processing apparatus 10 in the horizontal direction H and the vertical direction V, and outputs a detection signal HS indicating each direction H and a rotation angle VS in the direction V. The determination unit 22 determines the lateral direction H of the information processing apparatus 10 based on the detection signal HS of each angular velocity sensor 16, and determines the reciprocating rotation of the vertical direction V based on the detection signal VS.

FIG. 5 shows a change in the detection signal HS of the angular velocity sensor 16 when the information processing apparatus 10 is reciprocated in the lateral direction H. The reciprocating rotation means an operation in which the information processing apparatus 10 rotates in one direction from the initial state, then rotates in the opposite direction to return to the initial state. When the information processing device 10 is reciprocated in the lateral direction H, as shown in FIG. 5, the detection signal HS (indicating the displacement amount of the information processing device 10) of the angular velocity sensor 16 is the reciprocating rotation of the information processing device 10. It increases in the positive direction on the outward route, exceeds the threshold value + A, decreases after reaching a positive peak, becomes a displacement amount of 0 at the time point T0, and further decreases in the negative direction on the return route of the reciprocating rotation and falls below the threshold value -A. Instead, it increases again after reaching a negative peak, and the value settles near 0 displacement.

Here, the time zone from the time point T1 to the time point T0 when the detection signal HS starts to increase in the positive direction is set as the previous period ΔS1, and the value is around 0 after the detection signal HS starts to decrease in the negative direction from the time point T0. The time zone until the time point T2 when the temperature is settled is defined as the later period ΔS2. In this case, the detection signal HS exceeds the positive threshold value + A in the previous period ΔS1, and the detection signal HS falls below the negative threshold value −A in the latter period ΔS2.

Further, since the positive waveform of the detection signal HS in the previous period ΔS1 (outward route of reciprocating rotation) and the negative waveform of the detection signal HS in the latter period ΔS2 (return route of reciprocating rotation) are substantially equal, the detection in the previous period ΔS1 The sum of the positive integral value of the signal HS and the negative integral value of the detection signal HS in the later period ΔS2 becomes smaller, and this sum falls within a predetermined range M centered on 0.

On the other hand, when the direction of the reciprocating rotation of the information processing apparatus 10 in the lateral direction H is opposite, the detection signal HS of the angular velocity sensor 16 changes as shown in FIG. In FIG. 6, the detection signal HS of the angular velocity sensor 16 decreases in the negative direction on the outward path of the reciprocating rotation of the information processing device 10, falls below the threshold value −A, reaches a negative peak, and then increases at time point T0. It becomes 0, further increases in the positive direction on the return path of the reciprocating rotation, exceeds the threshold value + A, reaches a positive peak, and then decreases again. Therefore, the detection signal HS falls below the negative threshold value −A in the previous period ΔS1, and the detection signal HS exceeds the positive threshold value + A in the latter period ΔS2. Further, the sum of the negative integral value of the detection signal HS in the previous period ΔS1 and the positive integral value of the detection signal HS in the latter period ΔS2 falls within a predetermined range M centered on 0.

Here, it is assumed that the threshold value + A consisting of a positive value is set to a value sufficiently larger than the boundary value + B on the positive side of the predetermined range M. Further, it is assumed that the threshold value −A consisting of negative values is set to a value sufficiently smaller than the boundary value −B on the negative side of the predetermined range M. In other words, the positive boundary value + B of the predetermined range M is made sufficiently smaller than the positive threshold value + A, and the negative boundary value −B of the predetermined range M is set to the negative threshold value −A. Set sufficiently larger than.

Then, for example, the determination unit 22 periodically samples the value of the detection signal HS and sequentially stores it in the RAM built in the control unit 11, while detecting the detection signal HS for the length of time from the time point T1 to the time point T2. When the detection signal HS becomes 0, the value of the detection signal HS sampled in the pre-period ΔS1 before the time point T0 and the post-period ΔS2 after the time point T0 are always stored in the RAM. The value of the detection signal HS sampled in On the other hand, the detection signal HS is below the predetermined negative threshold value −A, and the sum of the integrated value of the detected signal HS in the previous period ΔS1 and the integrated value of the detected signal HS in the latter period ΔS2 is a predetermined range M. When entering, it is determined that the information processing apparatus 10 has been reciprocated in the lateral direction H.

Further, the determination unit 22 determines whether the detection signal HS does not exceed the positive threshold value + A in one of (i) the pre-period ΔS1 and the post-period ΔS2, or (ii) the (i) of the pre-period ΔS1 and the post-period ΔS2. The detection signal HS does not fall below the negative threshold value −A in different periods, or (iii) the sum of the integral value of the detection signal HS in the previous period ΔS1 and the integral value of the detection signal HS in the latter period ΔS2 is predetermined. If it is determined that the information processing device 10 does not fall within the range M, it is not determined that the information processing apparatus 10 has been reciprocated in the lateral direction H.

Similarly, when the information processing apparatus 10 is reciprocated in the vertical direction V, the detection signal VS of the angular velocity sensor 16 increases in the positive direction in the outward rotation of the information processing apparatus 10 and exceeds the threshold value + A. It becomes 0 at the time point T0, and further decreases in the negative direction on the return path of the reciprocating rotation to fall below the threshold value −A, or decreases in the negative direction on the outward path of the reciprocating rotation of the information processing apparatus 10 and falls below the threshold value −A. It becomes 0 at the time point T0, further increases in the positive direction on the return path of the reciprocating rotation, and exceeds the threshold value + A.

Further, the sum of the integral value of the detection signal VS in the previous period ΔS1 and the integral value of the detection signal VS in the latter period ΔS2 falls within a predetermined range M centered on 0. Therefore, the determination unit 22 periodically samples the value of the detection signal VS, and always stores the value of the detection signal VS for the length of time from the time point T1 to the time point T2 in the RAM for detection. When the signal VS becomes 0, the value of the detection signal VS sampled in the pre-period ΔS1 before the time point T0 and the value of the detection signal VS sampled in the post-time point ΔS2 after the time point T0 are read from the RAM. The detection signal VS in one of the pre-period ΔS1 and the post-period ΔS2 exceeds a predetermined positive threshold value + A, and the detection signal VS in the other of the pre-period ΔS1 and the post-period ΔS2 has a predetermined negative threshold value-. When the value is less than A and the sum of the integrated value of the detection signal VS in the previous period ΔS1 and the integrated value of the detected signal VS in the latter period ΔS2 falls within the predetermined range M, the information processing apparatus 10 reciprocates in the vertical direction V. Judge that it has been rotated.

Although the integral value of the detection signal in the previous period ΔS1 and the integral value of the detection signal in the latter period ΔS2 are illustrated, the determination unit 22 describes the positive or negative effective value of the detection signal in the previous period ΔS1 and the latter period ΔS2. It may be determined whether or not the sum of the negative or positive effective value of the detection signal in is within the predetermined range M. Further, the determination unit 22 sets the sum of the positive or negative average value or peak value of the detection signal in the previous period ΔS1 and the negative or positive average value or peak value of the detection signal in the latter period ΔS2 in a predetermined range M. It may be determined whether or not to enter.

<Determination of reciprocating movement of the information processing device 10 in the X-axis direction>
The acceleration sensor 15 detects the acceleration in the X-axis direction of the information processing apparatus 10 and outputs a detection signal XS indicating the acceleration. The determination unit 22 determines the reciprocating movement of the information processing apparatus 10 in the X-axis direction based on the detection signal XS of the acceleration sensor 15.

Also in this case, the detection output XS of the acceleration sensor 15 changes in the same manner as the detection signal HS of the angular velocity sensor 16 shown in FIG. After reaching the positive peak, it decreases to 0 at the time point T0, further decreases in the negative direction on the return path of the reciprocating movement, falls below the threshold value -A, and increases again after reaching the negative peak.

When the direction of the reciprocating movement of the information processing device 10 is opposite, the detection output XS of the acceleration sensor 15 changes in the same manner as the detection signal HS of the angular velocity sensor 16 shown in FIG. It decreases in the negative direction on the outbound route of movement, falls below the threshold value -A, increases after reaching a negative peak, becomes 0 at time point T0, and further increases in the positive direction on the return route of reciprocating movement, exceeding the threshold value + A. It reaches a positive peak and then decreases again.

Therefore, the determination unit 22 periodically samples the value of the detection signal XS and always stores the value of the detection signal XS for the length of time from the time point T1 to the time point T2 in the RAM for detection. When the signal XS becomes 0, the value of the detection signal XS sampled in the pre-period ΔS1 before the time point T0 and the value of the detection signal XS sampled in the post-time point ΔS2 after the time point T0 are read from the above RAM. , The detection signal XS in one of the pre-period ΔS1 and the post-period ΔS2 exceeds a predetermined positive threshold value + A, and the detection signal XS in the other of the pre-period ΔS1 and the post-period ΔS2 has a predetermined negative threshold value. When the value is less than −A and the sum of the integrated value of the detection signal XS in the previous period ΔS1 and the integrated value of the detected signal XS in the latter period ΔS2 falls within the predetermined range M, the information processing apparatus 10 moves in the X-axis direction. It is determined that the vehicle has been moved back and forth.

Thereby, according to the above embodiment, it is possible to determine that the reciprocating movement (including the reciprocating rotation) has been performed by a simple calculation process based on the output from the sensor such as the angular velocity sensor 16 and the acceleration sensor 15.

Further, similarly to the determination of the reciprocating movement in the X-axis direction, the determination unit 22 reciprocates in the Y-axis direction and the reciprocating movement in the Z-axis direction of the information processing apparatus 10 based on the detection signals YS and ZS of the acceleration sensor 15. May be determined.

The determination unit 22 not only determines the reciprocating rotation and reciprocating movement of the information processing apparatus 10, but also based on the detection signals HS, VS, and the detection signals XS, YS, and ZS of each angular velocity sensor 16. As shown in FIGS. 7A and 7B, in the state where the display screen is displayed on the screen 12A of the display unit 12, which direction is the information processing apparatus 10 in the vertical forward direction U or the vertical reverse direction D? Is determined. As shown in FIG. 7A, when the information processing apparatus 10 is in the vertical forward direction U, the information processing apparatus 10 is hung from the user's neck by the strap ST. Further, as shown in FIG. 7B, when the information processing apparatus 10 is in the upside-down direction D, the user holds the information processing apparatus 10 in his hand and turns the information processing apparatus 10 upside down. be.

Next, the display control of the display unit 12 of the information processing apparatus 10 will be described.

In the information processing device 10, a plurality of contents are stored in advance in the storage unit 13 in association with the orientation and displacement of the information processing device 10. When the determination unit 22 determines the orientation or displacement of the information processing device 10, the control unit 21 reads the content associated with the determined orientation or displacement from the storage unit 13, and displays the read content in the display unit 12. To display. Therefore, the content displayed on the display unit 12 is switched according to the orientation and displacement of the information processing apparatus 10. 8 (A) to 8 (F) exemplify the respective contents C1 to C6 that are switched and displayed on the display unit 12 according to the orientation and displacement of the information processing apparatus 10.

Next, a processing procedure for switching the content displayed on the display unit 12 according to the orientation and displacement of the information processing device 10 will be described with reference to the flowchart shown in FIG.

For example, the user hangs the strap ST of the information processing apparatus 10 around his / her neck and hangs the information processing apparatus 10 in the vertical forward direction U. The user activates the information processing apparatus 10 in this state (S101) . When information processing apparatus 10 is started, the determination unit 22, the detection signal XS from the acceleration sensor 15, YS, ZS, and the detection signal HS from the two angular velocity sensors 16, based on the VS, the information processing apparatus 10 Is determined to be the vertical forward direction U, and the control unit 21 initially sets the direction of the information processing apparatus 10 as the vertical forward direction U (S102).

Here, the storage unit 13 stores the employee ID card (content) C1 as the content associated with the vertical forward direction U. The control unit 21 reads the employee ID card (content) C1 associated with the vertical forward direction U from the storage unit 13, and causes the display unit 12 to display the employee ID card C1 as shown in FIG. 8 (A) (S103). ..

In the state where the vertical forward direction U is determined as the direction of the information processing apparatus 10, the control unit 21 determines that the information processing apparatus 10 is reciprocated in the X-axis direction by the determination unit 22 and the information processing apparatus. Despite the determination that the 10 has been reciprocated in either the horizontal direction H or the vertical direction V, the employee ID card C1 is continuously displayed on the display unit 12 (S105). Therefore, even if the information processing device 10 hung by the strap ST is shaken by the movement of the user, the employee ID card C1 is displayed on the display unit 12 as long as the direction of the information processing device 10 is determined to be the vertical forward direction U. Continues to be displayed in.

In the state where the vertical forward direction U is determined as the direction of the information processing device 10, the control unit 21 is waiting for the determination unit 22 to determine that the direction of the information processing device 10 is the vertical reverse direction D (). S106). If the determination unit 22 does not determine the orientation of the upside down direction D (No in S106), the control unit 21 repeats S105.

For example, when the user holds the information processing device 10 in his / her hand and turns the information processing device 10 upside down, and the determination unit 22 determines the direction D in the upside down direction (Yes in S106), the control unit 21 is determined by the determination unit 22 that the information processing device 10 has been reciprocated in the X-axis direction, and that the information processing device 10 has been reciprocated in either the vertical direction V or the horizontal direction H. Wait for information processing (S107).

Then, when it is determined by the determination unit 22 that the information processing apparatus 10 has reciprocated in the lateral direction D as described above (“lateral direction” in S107), the control unit 21 associates with the lateral direction H. The created schedule (content) C2 is read from the storage unit 13, and as shown in FIG. 8B, the schedule C2 is turned upside down from the employee ID card C1 and displayed on the display unit 12. (S109).

Further, when the determination unit 22 determines that the information processing apparatus 10 has reciprocated in the vertical direction V as described above (“vertical direction” in S107), the control unit 21 associates with the vertical direction V. The comment (content) C3 is read from the storage unit 13, and as shown in FIG. 8C, the comment C3 is turned upside down from the employee ID card C1 and displayed on the display unit 12 (S110). ..

Further, when the determination unit 22 determines that the information processing apparatus 10 has reciprocated in the X-axis direction as described above (“X-axis direction” in S107), the control unit 21 informs the determination unit 22. Each time it is repeatedly determined that the processing device 10 has reciprocated in the X-axis direction, the number N of this determination is cyclically counted in the range of 1 to 3 times. When the count value becomes 1, the control unit 21 reads out the image C4 showing the first graph, which is stored in the storage unit 13 in association with the count value 1, from the storage unit 13, and is an example in FIG. 8 (D). 1 is displayed on the display unit 12 with the first graph C4 turned upside down from the employee ID card C1.

Then, when the count value becomes 2, the control unit 21 reads out the second graph (content) C5 stored in the storage unit 13 in association with the count value 2 from the storage unit 13, and FIG. 8E shows. As shown in the example, the second graph C5 is displayed on the display unit 12 with the direction upside down from the employee ID card C1.

Further, when the count value becomes 3, the control unit 21 reads out the third graph (content) C6 stored in the storage unit 13 in association with the count value 3 from the storage unit 13, and FIG. 8 (F) As shown in the above, the third graph C6 is displayed on the display unit 12 with the direction upside down from the employee ID card C1.

When the count value returns to 1 (counting as the count value 1 after the count value 3), the control unit 21 causes the display unit 12 to display the first graph C4 again (S111). That is, the control unit 21 causes the display unit 12 to cyclically display the first graph C4 to the third graph C6 according to the number of reciprocating movements in the X-axis direction of the information processing device 10.

As described above, according to the present embodiment, after the user holds the information processing device 10 in his / her hand and turns the information processing device 10 upside down so that the direction of the information processing device 10 is upside down D, the information processing device 10 is turned upside down. When the information processing apparatus 10 is reciprocated in the horizontal direction H in the upside down direction D, the schedule C2 is displayed on the display unit 12, and the information processing apparatus 10 is reciprocated in the vertical direction V in the upside down direction D. When the information processing device 10 is rotated, the comment C3 is displayed on the display unit 12, and when the information processing apparatus 10 is reciprocated in the X-axis direction in the upside-down direction D, the first graphs C4 to No. 1 correspond to the number of swings. 3 Graph C6 is displayed cyclically.

During such switching display of the schedule C2, the comment C3, and the first graph C4 to the third graph C6, the control unit 21 is waiting for the determination unit 22 to determine the direction of the U in the vertical forward direction (). S112). Then, the control unit 21 repeats the process from S107 while the determination unit 22 does not determine the direction of the vertical forward direction U (No in S112). Further, when the determination unit 22 determines the direction of the U in the vertical forward direction (Yes in S112), the control unit 21 starts timing the duration of this determination, and the continuation time is a specified time (for example, 5). It is determined whether or not the time (seconds) has been reached (S113), and if the duration does not reach the specified time (No in S113), the process from S107 is repeated.

Further, when the duration reaches the specified time (Yes in S113), the control unit 21 returns to the processing from S103 and causes the display unit 12 to display the employee ID card C1 shown in FIG. 8A again. As a result, when the user hangs the strap ST around his / her neck and the information processing apparatus 10 is hung, the employee ID card C1 is displayed again on the display unit 12.

Further, the control unit 21 determines that the information processing device 10 has reciprocated in the X-axis direction by the determination unit 22, and that the information processing device 10 has been reciprocated in either the vertical direction V or the horizontal direction H. If neither of the determinations is made (No in S107), the orientation of the vertical forward direction U is not determined by the determination unit 22 (No in S112), or the orientation of the vertical forward direction U is determined by the determination unit 22. (Yes in S112) If the duration of this determination does not reach the specified time (No in S113), the process from S107 is repeated. When the duration reaches the specified time (Yes in S113), the control unit 21 returns to the processing from S103 and displays the employee ID card C1 on the display unit 12.

As described above, in the information processing apparatus 10 of the present embodiment, when the user hangs the strap ST around his / her neck and the information processing apparatus 10 is hung, the employee ID card C1 is displayed on the display unit 12, and information is displayed according to the movement of the user. Even if the processing device 10 is shaken, the control unit 21 maintains the display of the employee ID card C1 on the display unit 12 as long as the direction of the information processing device 10 is determined to be the vertical forward direction U by the determination unit 22. Maintaining such a display is suitable for using the information processing apparatus 10 as an ID card. Further, in a state where the user holds the information processing apparatus 10 in his hand and turns the information processing apparatus 10 upside down, the information processing apparatus 10 is reciprocated in the horizontal direction H, reciprocated in the vertical direction V, and in the X-axis direction. The schedule C2, the comment C3, the first graph C4 to the third graph C6 are switched and displayed according to the round-trip movement and the number of round-trip movements. Therefore, the information processing device 10 can be used as an ID card to display an employee ID card and to switch and display various contents by a simple operation.

In the above embodiment, a plurality of contents stored in advance in the storage unit 13 are switched and displayed, but the contents transmitted from an external transmitter (beacon or the like) are transmitted by the communication unit 14 of the information processing device 10. Upon reception, the control unit 21 stores each received content in the storage unit 13 in association with each direction of the information processing device 10, and the orientation and displacement of the information processing device 10 determined by the determination unit 22. It may be displayed on the display unit 12 according to the above.

For example, when information (contents) of a cafeteria or a conference room is transmitted from a transmitter installed in a cafeteria or a conference room to the information processing apparatus 10, the information processing apparatus 10 receives the contents in the communication unit 14. The control unit 21 stores this content in the storage unit 13 in association with, for example, the reciprocating rotation in the vertical direction V. Then, when the information processing device 10 is reciprocated in the vertical direction V and the determination unit 22 determines the reciprocating rotation in the vertical direction V with the information processing device 10 turned upside down, the control unit 21 is in the vertical direction. The content associated with the reciprocating rotation of V is read from the storage unit 13 and displayed on the display unit 12.
