Embodiment 1
Hereinafter, embodiments of the present invention will be described in detail. In one embodiment of the present invention, an example in which the information processing apparatus of the present invention is applied to a mobile device such as a smartphone having a call function as a mobile terminal will be described.

(Mobile device)
FIG. 1 is a block diagram illustrating a schematic configuration of a mobile device (mobile terminal) 101 according to the present embodiment. The mobile device 101 is a mobile terminal having a call function such as a smartphone, and includes a display unit 1, a gyro sensor (angular velocity sensor) 2, and a control unit 3. In the present embodiment, since the call function of the mobile device 101 is not the essence of the invention, detailed description thereof is omitted.

  The display unit 1 displays various information such as images such as telephone numbers and photographs, and is composed of an LCD (Liquid Crystal Display). The display unit 1 is not limited to the LCD, and may be another display panel such as an organic EL (Electroluminescence).

  The gyro sensor 2 is an angular velocity sensor that detects an angular velocity around the axis of the portable device (housing) 101 that is an angular velocity generated in the portable device (housing) 101. For example, as shown in FIG. 2A, the display surface of the display unit 1 of the portable device 101 is the front surface, the horizontal axis is the X axis, the vertical axis is the Y axis, and the direction perpendicular to the display surface is When the axis is the Z axis, the gyro sensor 2 detects the angular velocity around the X axis, the angular velocity around the Y axis, and the angular velocity around the Z axis in the portable device 101 as shown in FIG. It is. Then, the gyro sensor 2 converts the detected angular velocity around each axis into an electrical signal (angular velocity information) and sends it to the control unit 3.

  The control unit 3 includes a function execution control unit (information processing device) 10, a function execution unit 20, and a timer unit 30. The function execution control unit 10 includes an angular velocity information acquisition unit 11, a function execution determination unit 12, and a rotation angle calculation unit 13.

  The angular velocity information acquisition unit 11 acquires an electrical signal (angular velocity information) from the gyro sensor 2 and passes the electrical signal (angular velocity information) to each of the function execution determination unit 12 and the rotation angle calculation unit 13.

  The rotation angle calculation unit 13 includes a first polarity rotation angle (first rotation angle) that is a time integral of the angular velocity of the first polarity indicated by the angular velocity information acquired by the angular velocity information acquisition unit 11, and the above-described first value indicated by the angular velocity information. A second polarity rotation angle (second rotation angle), which is the time integral of the angular velocity of the second polarity, which is opposite to the first polarity, is calculated and passed to the function execution determination unit 12.

  The first polarity rotation angle (first rotation angle) is the moment when the portable device 101 starts to rotate to the second polarity around the Y-axis (in this case, strictly stops temporarily). Is calculated by integrating the angular velocity of the first polarity. On the other hand, the second polarity rotation angle (second rotation angle) is calculated by integrating the angular velocity of the second polarity with respect to the time from when the portable device 101 starts rotating around the Y axis until it stops. The angular velocity information acquired by the angular velocity information acquisition unit 11, the first polarity rotation angle (first rotation angle) calculated by the rotation angle calculation unit 13, and the second polarity rotation angle (second rotation angle) are illustrated in the drawing. May be temporarily recorded in a memory that does not.

  The function execution determination unit 12 includes the angular velocity information acquired by the angular velocity information acquisition unit 11 and the first polarity rotation angle (first rotation angle) and the second polarity rotation angle (second rotation angle) calculated by the rotation angle calculation unit 13. ), And whether or not to execute a preset function based on the time measured by the timer unit 30 is determined. Details of the determination processing by the function execution determination unit 12 will be described later.

  The function execution unit 20 receives the result determined by the function execution determination unit 12 to execute the preset function and executes the preset function. In the present embodiment, a preset function will be described as a function for turning pages of an electronic book displayed on the display unit 1. Accordingly, the function execution unit 20 instructs the display unit 1 to execute page turning of the electronic book, which is a preset function. Here, the preset function is associated with, for example, a twist having the Y axis of the mobile device 101 as the central axis. This twist is an operation in which a user holding the mobile device 101 rotates the mobile device 101 in one direction around the Y axis and then rotates it in the opposite direction.

  Thus, by twisting the mobile device 101, the page of the electronic book displayed on the display unit 1 of the mobile device 101 is turned. When the twist of the mobile device 101 starts clockwise, the page of the electronic book is turned right, and when the twist starts counterclockwise, the page turning function is set so that the page of the electronic book is turned left. Is preferred. Thereby, the operation | movement which turns the page of an electronic book can be performed intuitively. Hereinafter, detection of twist associated with the portable device 101 in order to execute a preset function will be described.

(Determination of twist)
FIG. 5 shows a waveform diagram of the angular velocity detected by the gyro sensor 2 when the mobile device 101 performs twisting. FIG. 6 is a diagram illustrating an image in which the mobile device 101 is twisted around the Y axis. Here, the polarity of the angular velocity obtained when the mobile device 101 rotates clockwise around the Y axis is positive (first polarity), and the polarity of the angular velocity obtained by rotating counterclockwise is negative (second polarity). ).

  The twist of the portable device 101 is determined by the function execution determination unit 12 described above. That is, when the twist of the mobile device 101 starts clockwise, as shown in FIG. 5A, the absolute value of the angular velocity of the first polarity indicated by the angular velocity information acquired by the angular velocity information acquisition unit 11 is set in advance. After the upper waveform detection threshold value S1a, which is the first threshold value, is exceeded, the absolute value of the angular velocity of the second polarity opposite to the first polarity indicated by the angular velocity information is the second threshold value set in advance. If the waveform detection threshold value S1b is exceeded, it is determined that the mobile device 101 has been twisted.

  On the other hand, when the twist of the mobile device 101 starts counterclockwise, as shown in FIG. 5B, the absolute value of the angular velocity of the second polarity indicated by the angular velocity information acquired by the angular velocity information acquisition unit 11 is set in advance. After the lower waveform detection threshold value S1b, which is the second threshold value, is exceeded, the absolute value of the angular velocity of the first polarity opposite to the second polarity indicated by the angular velocity information is the first threshold value set in advance. If the waveform detection threshold S1a is exceeded, it is determined that the mobile device 101 has been twisted.

  Here, it is preferable that the above condition is satisfied within a preset time (twist determination time t1) regardless of whether the twist of the mobile device 101 starts clockwise or starts counterclockwise. That is, after the absolute value of the angular velocity of the first polarity exceeds a preset first threshold (upper waveform detection threshold S1a or lower waveform detection threshold S1b), the absolute value of the angular velocity of the second polarity is set in advance. If the time (waveform detection time t) required to exceed the second threshold (lower waveform detection threshold S1b or upper waveform detection threshold S1a) is within a preset time (twist determination time t1), the portable device 101 It is determined that twisting has been performed.

  According to the above configuration, after the absolute value of the angular velocity of the first polarity detected by the gyro sensor 2 exceeds the first threshold value, the function execution determining unit 12 determines that the absolute value of the angular velocity of the second polarity is the second threshold value. In order to execute the function set in advance by the operation of the mobile device 101, the condition whether or not the time required to exceed the time is within the time set in advance is added to the condition for executing the function set in advance. It is possible to more appropriately determine whether or not the operation is.

  By the way, depending on the operation of the mobile device 101, a function that is determined as a twist and is not intended by the user may be executed. For example, even when the user throws the portable device 101 onto the bed or shakes the portable device 101, the gyro sensor 2 detects the angular velocity around the Y axis, and (a) and ( The waveform shown in b) is obtained, and it is determined as a twist, and there is a possibility that a function not intended by the user is executed.

(Rotation angle judgment)
In the present embodiment, a twist operation of the mobile device 101 for executing a preset function is distinguished from a twist of the mobile device 101 when the mobile device 101 is thrown on the bed or the mobile device 101 is shaken. Therefore, at least one of the absolute value of the first polarity rotation angle that is the time integration of the angular velocity of the first polarity and the absolute value of the second polarity rotation angle that is the time integration of the angular velocity of the second polarity is It is determined whether or not a preset rotation angle threshold is exceeded. Here, both the first polarity rotation angle (first rotation angle) and the second polarity rotation angle (second rotation angle) are both predetermined rotation angle thresholds (first rotation angle detection threshold S2a or second rotation angle detection). If the threshold value S2b) is not exceeded, it is determined that the operation is such that the portable device 101 is thrown on the bed or the portable device 101 is shaken.

  FIG. 3 is a waveform diagram of the angular velocity and rotation angle around the Y axis of the mobile device 101. FIG. 3A shows a waveform diagram of the angular velocity around the Y axis of the portable device 101 when the portable device 101 is thrown on the bed or when the portable device 101 is shaken. At this time, after the absolute value of the clockwise angular velocity of the first polarity exceeds the preset first threshold value (upper waveform detection threshold S1a), the absolute value of the counterclockwise second polarity angular velocity is set in advance. The time (waveform detection time t) required to exceed the second threshold (lower waveform detection threshold S1b) is shorter than that shown in FIG. 3C. Therefore, as shown in FIG. 3B, the absolute value of the first polarity rotation angle, which is the time integral of the angular velocity of the first polarity, is set to a preset rotation angle threshold (first rotation angle detection threshold S2a). The absolute value of the second polarity rotation angle that is the time integral of the angular velocity of the second polarity does not exceed a preset rotation angle threshold (second rotation angle detection threshold S2b).

  The value of the first polarity rotation angle corresponds to the difference between the value of the flat portion and the value of the top portion in the waveform diagram of the rotation angle. On the other hand, the value of the second polarity rotation angle corresponds to the difference between the value of the top portion and the value of the flat portion in the waveform diagram of the rotation angle.

  On the other hand, FIG. 3C shows a waveform diagram of the angular velocity around the Y axis of the portable device 101 when the portable device 101 is twisted. At this time, the waveform detection time t is longer than the case shown in FIG. For this reason, as shown in FIG. 3D, the absolute value of the first polarity rotation angle exceeds the preset rotation angle threshold (first rotation angle detection threshold S2a), and further, the second polarity rotation angle The absolute value also exceeds a preset rotation angle threshold (second rotation angle detection threshold S2b) (waveform detection time t = twist determination time t1).

  That is, the portable device 101 according to the present embodiment is configured so that at least one of the first polarity rotation angle and the second polarity rotation angle (rotation angle) when twisted is somewhat large and exceeds a preset rotation angle threshold. It is determined that the mobile device 101 has performed the twist operation.

(Twist detection process)
The flow of the twist operation detection process of the mobile device 101 will be described below with reference to the flowchart shown in FIG. The twisting operation of the portable device 101 detected in this process is a twisting operation for executing a preset function, that is, a function for turning pages of an electronic book. In the following description, the terminal indicates the mobile device 101, and the gyro indicates the angular velocity detected by the gyro sensor 2.

  First, the angular velocity information acquisition unit 11 acquires the gyro (Y axis) of the terminal at regular intervals (step S11). Specifically, the angular velocity information acquisition unit 11 acquires angular velocity information indicating the angular velocity around the Y axis of the mobile device 101 from the gyro sensor 2 at regular intervals.

  Next, the function execution determination unit 12 determines whether or not the value of the gyro (Y axis) satisfies the first waveform detection condition (step S12). Specifically, the function execution determination unit 12 satisfies the first waveform detection condition from the angular velocity value obtained from the angular velocity information acquired by the angular velocity information acquisition unit 11 and the waveform diagram showing the passage of time, that is, in FIG. It is determined whether or not the absolute value of the angular velocity of the first polarity shown exceeds the upper waveform detection threshold value S1a. If it is determined that the value of the gyro (Y axis) satisfies the first waveform detection condition (YES), the process proceeds to step S13. On the other hand, if it is determined (NO) that the value of the gyro (Y axis) does not satisfy the first waveform detection condition, the process returns to S12.

  In step S13, the function execution determination unit 12 determines whether or not a predetermined time (t) has elapsed. Specifically, the function execution determination unit 12 determines whether or not a fixed time (t) has elapsed since it was determined as YES in step S12 measured by the timer unit 30. Here, if it is determined (YES) that the predetermined time (t) has elapsed, the process proceeds to step S12 again, and if it is determined (NO) that the predetermined time (t) has not elapsed, the process proceeds to step S14.

  In step S14, the rotation angle calculation unit 13 calculates the rotation angle (first polarity rotation angle) of the first waveform, stores it in the memory, and proceeds to S15.

  In step S15, the function execution determination unit 12 determines whether or not the gyro (Y axis) value satisfies the second waveform detection condition. Specifically, the function execution determination unit 12 determines that the second waveform detection condition is satisfied from the angular velocity value obtained from the angular velocity information acquired by the angular velocity information acquisition unit 11 and the waveform diagram showing the passage of time, that is, in FIG. It is determined whether or not the absolute value of the angular velocity of the second polarity shown exceeds the lower waveform detection threshold S1b. If it is determined that the value of the gyro (Y axis) satisfies the second waveform detection condition (YES), the process proceeds to step S16. On the other hand, if it is determined (NO) that the value of the gyro (Y axis) does not satisfy the second waveform detection condition, the process returns to S13.

  In step S16, the rotation angle calculation unit 13 calculates the rotation angle (second polarity rotation angle) of the second waveform, stores it in the memory, and proceeds to S17.

  In step S17, the function execution determination unit 12 reads the rotation angle (first polarity rotation angle) of the first waveform and the rotation angle (second polarity rotation angle) of the second waveform from the memory, and any of these rotation angles. Is over a predetermined threshold (first rotation angle detection threshold S2a or second rotation angle detection threshold S2b). If it is determined (YES) that either the rotation angle of the first waveform (first polarity rotation angle) or the rotation angle of the second waveform (second polarity rotation angle) exceeds a predetermined threshold (YES), the process proceeds to S18. On the other hand, if it is determined that both the rotation angle of the first waveform (first polarity rotation angle) and the rotation angle of the second waveform (second polarity rotation angle) do not exceed the predetermined threshold (NO), the process proceeds to S12. Return.

  In step 18, the function execution determination unit 12 determines that the portable device 101 has performed the twist operation, determines that the preset function is to be executed, and ends.

  As described above, in the portable device 101, the function execution determination unit 12 determines that the absolute value of the angular velocity of the second polarity is the second threshold value after the absolute value of the angular velocity of the first polarity exceeds the preset first threshold value. And the absolute value of the first polarity rotation angle that is the time integration of the angular velocity of the first polarity and the absolute value of the second polarity rotation angle that is the time integration of the angular velocity of the second polarity. If one exceeds a preset rotation angle threshold, a preset function is executed. That is, the function execution determination unit 12 performs the first polarity rotation even when the angular velocity of the second polarity exceeds the second threshold after the angular velocity of the first polarity exceeds the preset first threshold. If both the absolute value of the angle and the absolute value of the second polarity rotation angle are equal to or less than the preset rotation angle threshold, the preset function is not executed.

  Thereby, the function execution determination unit 12 has three conditions, (1) the absolute value of the angular velocity of the first polarity exceeds the first threshold value, and (2) the absolute value of the angular velocity of the second polarity sets the second threshold value. Exceeded, and (3) at least one of the absolute value of the first polarity rotation angle and the absolute value of the second polarity rotation angle exceeds a preset rotation angle threshold, and is preset. Since it is determined to execute the function, it is possible to appropriately determine whether or not the operation of the mobile device 101 is an operation for executing a preset function.

  After the fourth condition, step S13 in FIG. 4, that is, after the absolute value of the angular velocity of the first polarity exceeds the preset first threshold value (upper waveform detection threshold value S1a or lower waveform detection threshold value S1b). The time (waveform detection time t) required until the absolute value of the angular velocity of the second polarity exceeds the preset second threshold (lower waveform detection threshold S1b or upper waveform detection threshold S1a) is a preset time ( If it is within the twist determination time t1), it is determined whether the operation of the mobile device 101 is an operation for executing a preset function even if the determination that the mobile device 101 has performed the twist is omitted. Can be performed with high accuracy.

[Embodiment 3: Implementation by software]

Alternatively, it may be realized by software using a CPU (Central Processing Unit).
