1. Embodiment 1-1. Configuration FIG. 1 is a diagram showing an appearance of a wristwatch type information processing apparatus 1 according to the present embodiment. The information processing apparatus 1 has a feature that a screen can be displayed according to the movement of the user's arm. As shown in FIG. 1, the information processing apparatus 1 includes a housing 2 and a belt 3. The housing 2 stores electronic components constituting the information processing apparatus 1 described later. The belt 3 is a member for fixing the information processing apparatus 1 to the user's wrist. A touch panel 13 to be described later is exposed on the surface of the housing 2 (the surface opposite to the surface facing the wrist).

  FIG. 2 is a block diagram illustrating a hardware configuration of the information processing apparatus 1. As illustrated in FIG. 2, the information processing apparatus 1 includes a CPU (Central Processing Unit) 11, a memory 12, a touch panel 13, and an acceleration sensor 14.

  The CPU 11 controls each component of the information processing apparatus 1 by executing a program stored in the memory 12. The memory 12 is a flash memory, for example, and stores a program executed by the CPU 11. The touch panel 13 includes a liquid crystal display and a touch pad arranged on the liquid crystal display, displays a screen, and accepts an input operation from a user. The touch panel 13 displays a screen showing the current time, for example. The acceleration sensor 14 is a triaxial acceleration sensor, for example, and measures the acceleration of the information processing apparatus 1.

  FIG. 3 is a diagram illustrating a configuration of functions realized by the CPU 11 of the information processing apparatus 1. When the CPU 11 executes the program stored in the memory 12, as shown in FIG. 3, the locus specifying unit 111, the process executing unit 112, the instruction receiving unit 113, the first correction unit 114, and the second correction unit 114 are executed. The function of the correction unit 115 is realized. These functions relate to screen display processing described later.

  The locus specifying unit 111 specifies a movement locus of the information processing apparatus 1. Specifically, the locus specifying unit 111 specifies the waveform of acceleration measured by the acceleration sensor 14. FIG. 4 is a diagram illustrating an example of a change in acceleration measured by the acceleration sensor 14 as a waveform. The horizontal axis indicates time, and the vertical axis indicates acceleration. The locus specifying unit 111 specifies a waveform such as W1 shown in FIG. In addition, when the acceleration sensor 14 can measure acceleration with two or more axes, the trajectory specifying unit 111 specifies an acceleration waveform for each axis.

  The process executing unit 112 executes a predetermined process when the trajectory specified by the trajectory specifying unit 111 is included in a predetermined range with reference to the first reference trajectory. Specifically, the process execution unit 112 executes a predetermined process when the acceleration waveform identified by the trajectory identification unit 111 is included in a predetermined range centered on the first reference waveform. To do. Here, the predetermined process is a process of displaying a screen on the touch panel 13, for example.

  FIG. 5 is a diagram illustrating an example of the first reference waveform and a predetermined range centered on the first reference waveform. The horizontal axis indicates time, and the vertical axis indicates acceleration. In FIG. 5, R1 represents the first reference waveform, L1 represents the upper limit of the range centered on the first reference waveform R1, and L2 represents the lower limit of the range centered on the first reference waveform R1. W2 represents an example of an acceleration waveform measured by the acceleration sensor 14.

  In the example shown in FIG. 5, each acceleration value constituting the waveform W <b> 2 is associated with the same time as the value and falls between the upper limit value and the lower limit value indicated by the lines L <b> 1 and L <b> 2. That is, the waveform W2 is included in a predetermined range centered on the first reference waveform R1. Therefore, when the waveform W2 is specified by the trajectory specifying unit 111 and collated with a predetermined range centered on the first reference waveform R1, the process executing unit 112 executes a predetermined process. Note that the width of the predetermined range in the vertical axis direction may be set arbitrarily.

  When the acceleration sensor 14 can measure acceleration with two or more axes, a first reference waveform is prepared for each axis. Then, in all axes, when the acceleration waveform specified by the trajectory specifying unit 111 is included in a predetermined range based on the first reference waveform, the process executing unit 112 performs a predetermined process. Run.

  In addition, the process execution unit 112 also includes the second reference trajectory even when the trajectory specified by the trajectory specifying unit 111 is included in a predetermined range based on the first reference trajectory. If it is included in a predetermined range with reference to, the predetermined processing is not executed. Specifically, even when the processing execution unit 112 includes the acceleration waveform specified by the locus specifying unit 111 within a predetermined range centered on the first reference waveform, When it falls within a predetermined range centered on the second reference waveform, the predetermined process is not executed. Here, the predetermined process is a process of displaying a screen on the touch panel 13, for example.

  FIG. 6 is a diagram illustrating an example of the second reference waveform and a predetermined range centered on the second reference waveform. The horizontal axis indicates time, and the vertical axis indicates acceleration. In FIG. 6, R2 represents the second reference waveform, L3 represents the upper limit of the range centered on the second reference waveform R2, and L4 represents the lower limit of the range centered on the second reference waveform R2. W3 represents an example of an acceleration waveform measured by the acceleration sensor 14.

  In the example shown in FIG. 6, each acceleration value constituting the waveform W <b> 3 is associated with the same time as the value and falls between the upper limit value and the lower limit value indicated by the lines L <b> 3 and L <b> 4. That is, the waveform W3 is included in a predetermined range centered on the second reference waveform R2. Therefore, when the waveform specifying unit 111 specifies the waveform W3 and collates it with a predetermined range centered on the second reference waveform R2, the waveform W3 is temporarily determined centering on the first reference waveform R1. Even if included in the range, the process execution unit 112 does not execute the predetermined process. Note that the width of the predetermined range in the vertical axis direction may be set arbitrarily.

  When the acceleration sensor 14 can measure acceleration with two or more axes, a second reference waveform is prepared for each axis. When the acceleration waveform specified by the locus specifying unit 111 is included in a predetermined range centered on the second reference waveform for all axes, the process executing unit 112 performs a predetermined process. Do not execute.

  The instruction receiving unit 113 receives an instruction from the user. Specifically, the instruction receiving unit 113 receives an instruction from a user input via the touch panel 13. For example, the instruction receiving unit 113 receives an instruction for processing by the first correction unit. Specifically, the instruction receiving unit 113 is a process for allowing a trajectory of movement of the information processing apparatus that is not permitted as a trigger for execution of a predetermined process by the current process executing unit 112 as the trigger. Accept the instructions.

  The instruction receiving unit 113 receives an instruction for processing by the second correction unit 115. Specifically, the instruction receiving unit 113 performs a process for preventing the movement trajectory of the information processing apparatus that is currently permitted as a trigger for execution of the predetermined process by the process execution unit 112 from being permitted as the trigger. Accept instructions.

  The first correction unit 114 corrects the first reference trajectory based on the trajectory specified by the trajectory specifying unit 111. For example, the first correcting unit 114 receives the predetermined instruction from the user when the instruction receiving unit 113 receives the predetermined instruction when the process executing unit 112 is not executing the predetermined process. The first reference trajectory is corrected based on the trajectory that has been specified by the trajectory specifying unit 111 until then.

  Specifically, the first correction unit 114 corrects the first reference waveform based on the acceleration waveform specified by the locus specifying unit 111. More specifically, the first correction unit 114 determines the acceleration specified by the trajectory specifying unit 111 within a predetermined time (for example, 2 seconds) immediately before the instruction receiving unit 113 receives a predetermined instruction from the user. A waveform is added to a group of acceleration waveforms instructed to be registered as a trigger for execution of a predetermined process by the process execution unit 112 in the past, and a weighted average waveform of these waveforms is specified.

  The second correction unit 115 corrects the second reference trajectory based on the trajectory specified by the trajectory specifying unit 111. For example, the second correction unit 115 may be configured by the trajectory specifying unit 111 when a predetermined instruction from the user is received by the instruction receiving unit 113 within a predetermined period after the processing execution unit 112 executes a predetermined process. The second reference trajectory is corrected based on the identified trajectory.

  Specifically, the second correction unit 115 corrects the second reference waveform based on the acceleration waveform specified by the locus specifying unit 111. More specifically, the second correction unit 115 has been instructed to exclude the acceleration waveform identified by the trajectory identification unit 111 as a trigger for executing a predetermined process by the process execution unit 112 in the past. In addition, the weighted average waveform of these waveforms is specified.

1-2. Operation Next, the operation of the information processing apparatus 1 will be described. Specifically, registration processing and screen display processing will be described. Here, the registration process is a process for registering, as a trigger, a movement trajectory of the information processing apparatus that has not been allowed as a conventional screen display trigger. The screen display process is a process of displaying a screen on the touch panel 13 according to the movement path of the information processing apparatus 1.

1-2-1. Registration Processing When a predetermined input operation is performed on the touch panel 13 by the user, the CPU 11 of the information processing apparatus 1 displays an acceleration waveform measured by the acceleration sensor 14 within a predetermined time immediately before the input operation is performed. Register as a screen display trigger. For example, when a double-tap operation is performed on the touch panel 13, the CPU 11 registers the acceleration waveform measured by the acceleration sensor 14 during the two seconds immediately before the operation is performed as a screen display trigger. The user of the information processing apparatus 1 performs a certain operation while carrying the information processing apparatus 1 and then performs a double tap operation on the touch panel 13, thereby registering the locus of the operation as a trigger for screen display. be able to.

  When the registration process is the first registration process (that is, when the first reference waveform data is not stored in the memory 12), the CPU 11 determines the acceleration measured by the acceleration sensor 14. Data indicating the waveform is stored in the memory 12 as data of the first reference waveform. On the other hand, when the registration process is not the first registration process (that is, when the data of the first reference waveform is already stored in the memory 12), the CPU 11 determines the acceleration measured by the acceleration sensor 14. A waveform is added to a group of acceleration waveforms that have been registered in the past as screen display triggers, a weighted average waveform of these waveforms is specified, and data indicating the specified waveform is data of the first reference waveform. Is stored in the memory 12.

1-2-2. Screen Display Processing FIG. 7 is a flowchart showing screen display processing. In the following description, it is assumed that the screen of the touch panel 13 is not displayed due to the shift to the power saving mode at the start of this process.

  In this screen display process, the CPU 11 of the information processing apparatus 1 continues to determine whether or not the acceleration waveform measured by the acceleration sensor 14 is included in a predetermined range centered on the first reference waveform. (Step Sa1). As a result of this determination, when a waveform included in a predetermined range centered on the first reference waveform is detected (step Sa1; YES), the CPU 11 executes the process of step Sa2.

  In step Sa2, the CPU 11 determines whether or not the waveform determined to be included in the predetermined range centered on the first reference waveform in step Sa1 is included in the predetermined range centered on the second reference waveform. Determine whether or not. As a result of this determination, when the waveform is included in a predetermined range centered on the second reference waveform (step Sa2; YES), the CPU 11 executes the process of step Sa1 again. On the other hand, as a result of the determination, if the waveform is not included in a predetermined range centered on the second reference waveform (step Sa2; NO), the CPU 11 displays a screen on the touch panel 13 (step Sa3). .

  After displaying the screen on the touch panel 13, the CPU 11 determines whether or not a predetermined input operation has been performed on the touch panel 13 for a predetermined period (step Sa4). For example, the CPU 11 determines whether or not a double tap operation has been performed on the touch panel 13 for 2 seconds after the screen is displayed on the touch panel 13. If the screen display in step Sa3 is not intended, the user of the information processing apparatus 1 performs a double tap operation on the touch panel 13 at this timing.

  As a result of the determination, when a predetermined input operation is not performed on the touch panel 13 (step Sa4; NO), the CPU 11 ends the screen display process. On the other hand, as a result of the determination, when a predetermined input operation is performed on the touch panel 13 (step Sa4; YES), the CPU 11 hides the screen of the touch panel 13 (step Sa5).

Next, the CPU 11 corrects the second reference waveform based on the waveform determined to be included in the predetermined range centered on the first reference waveform in Step Sa1 (Step Sa6). Specifically, the CPU 11 determines the acceleration having been instructed to be excluded as a screen display trigger in the past as a waveform determined to be included in a predetermined range centered on the first reference waveform in step Sa1. In addition to the waveform group, a weighted average waveform of these waveforms is specified, and data indicating the specified waveform is stored in the memory 12 as second reference waveform data. After executing the process of step Sa6, the CPU 11 executes the process of step Sa1 again.
The above is the content of this screen display process.

  According to the information processing apparatus 1 according to the present embodiment described above, the user can cause the information processing apparatus 1 to display a screen using the operation as a trigger by registering the user's own operation in advance. Further, when an unintended screen display is performed as a result of some operation, the operation can be excluded from the screen display trigger. Conversely, if the screen is not displayed even though the user has performed an operation recognized as a screen display trigger, the operation can be additionally registered as a screen display trigger.

2. Modifications The above embodiment may be modified as follows. The following modifications may be combined with each other.

2-1. Modification 1
In the above embodiment, when an acceleration waveform is additionally registered as a screen display trigger, the waveform is added to the acceleration waveform group previously registered as a screen display trigger, and then the waveforms are displayed. The weighted average waveform is specified, and data indicating the specified waveform is stored in the memory 12 as data of the first reference waveform. However, instead of this process, a process of expanding a predetermined range of the first reference waveform may be performed. Specifically, a process of increasing the upper limit defining a predetermined range of the first reference waveform and decreasing the lower limit may be performed.

  FIG. 8 is a diagram illustrating an example of this processing. In FIG. 8, the horizontal axis indicates time, and the vertical axis indicates acceleration. R3 represents the first reference waveform, L5 represents the upper limit of the range centered on the first reference waveform R3, and L6 represents the lower limit of the range centered on the first reference waveform R3. W4 represents an example of an acceleration waveform measured by the acceleration sensor 14.

  In the example shown in FIG. 8A, the waveform W4 is not included in the range centered on the first reference waveform R3, but in the example shown in FIG. 8B, the first reference waveform R3. By raising the upper limit L5 of the range centered on the waveform W4, the waveform W4 is included in the range centered on the first reference waveform R3.

  When this modification is adopted, the first correction unit realized by the CPU 11 corrects a predetermined range based on the first reference locus based on the locus specified by the locus specifying unit 111. . For example, the first correcting unit 114 receives the predetermined instruction from the user when the instruction receiving unit 113 receives the predetermined instruction when the process executing unit 112 is not executing the predetermined process. The predetermined range based on the first reference trajectory is corrected based on the trajectory that has been specified by the trajectory specifying unit 111.

  In the above-described embodiment, the same processing may be performed when the acceleration waveform is excluded from the screen display trigger. Specifically, in step Sa6 of the screen display process described above, a process of expanding a predetermined range of the second reference waveform may be performed. However, in this case, processing is performed to lower the upper limit that defines the predetermined range of the second reference waveform and raise the lower limit.

  When this modification is adopted, the second correction unit 115 realized by the CPU 11 corrects a predetermined range based on the second reference trajectory based on the trajectory specified by the trajectory specifying unit 111. To do. For example, the second correction unit 115 may be configured by the trajectory specifying unit 111 when a predetermined instruction from the user is received by the instruction receiving unit 113 within a predetermined period after the processing execution unit 112 executes a predetermined process. Based on the identified trajectory, a predetermined range based on the second reference trajectory is corrected.

2-2. Modification 2
In the above-described embodiment, the length of the first reference waveform and the length of the acceleration waveform measured by the acceleration sensor 14 compared with the first reference waveform may be corrected. For example, in the above registration process, when an acceleration waveform is additionally registered, the length of the first reference waveform and the first reference waveform are set in order to facilitate screen display using the waveform as a trigger. You may make it shorten the length of the waveform of the acceleration compared with a waveform.

  FIG. 9 is a diagram illustrating an example of this processing. In FIG. 9, the horizontal axis indicates time, and the vertical axis indicates acceleration. W5 represents an example of an acceleration waveform measured by the acceleration sensor 14. As shown in FIG. 9, the length of the acceleration waveform measured by the acceleration sensor 14 may be shortened from 2.0 seconds to 1.5 seconds, for example. With this correction, the length of the first reference waveform may be shortened as well.

  When this modification is adopted, the first correction unit realized by the CPU 11 described above is such that the trajectory specifying unit 111 specifies the trajectory of movement of the information processing apparatus 1 for a predetermined time, and the process executing unit 112 is When the trajectory specified by the specifying unit 111 is included in a first range based on the first reference trajectory for the predetermined time, when the predetermined process is executed, the predetermined time is The predetermined time is corrected so as to be shorter.

  Further, in the above screen display processing, when a screen is displayed at a timing not intended by the user (that is, when a predetermined input operation is performed on the touch panel 13 in step Sa4), step Sa1 is performed. In order to make the determination process stricter, the length of the first reference waveform and the length of the acceleration waveform compared with the first reference waveform may be increased.

  When this modification is adopted, the second correction unit 115 realized by the CPU 11 described above is such that the locus specifying unit 111 specifies a movement locus of the information processing apparatus 1 for a predetermined time, and the process execution unit 112 is When the trajectory specified by the trajectory specifying unit 111 is included in a first range based on the first reference trajectory for the predetermined time, when the predetermined process is executed, the predetermined time The predetermined time is corrected so as to be longer.

2-3. Modification 3
The information processing apparatus 1 according to the above embodiment may be a mobile phone, a smartphone, a PDA (Personal Digital Assistant), or a tablet terminal. Further, the information processing apparatus 1 may be a remote controller of a device such as a television or an air conditioner. Further, the information processing apparatus 1 may be other wearable information processing apparatuses such as a glasses type other than the wristwatch type. In the above embodiment, the means for accepting an input operation by the user is not limited to the touch pad according to the above embodiment, but may be a button (hard button).

2-4. Modification 4
The process executed by the CPU 11 in step Sa3 of the screen display process is not limited to the process of displaying a screen on the touch panel 13. For example, if it is assumed that the screen is displayed on the touch panel 13 at the start of the screen display process, the CPU 11 may execute the process of hiding the screen of the touch panel 13 in step Sa3. Good. Alternatively, the CPU 11 may execute processing for switching to a predetermined screen. In addition to the screen display process, for example, when the information processing apparatus 1 has a music reproduction function, reproduction of music may be started in step Sa3. Conversely, the reproduction of music may be stopped.

2-5. Modification 5
In the above embodiment, the first reference waveform may be changed according to the moving method of the user carrying the information processing apparatus 1. Here, the moving method is, for example, walking, running, bicycle, motorcycle, automobile, train or the like.

  FIG. 10 is a diagram illustrating a configuration example of the reference waveform information database (DB) 121 stored in the memory 12 of the information processing apparatus 1 when this modification is employed. The reference waveform information DB 121 is a database that stores the acceleration waveform measured by the acceleration sensor 14 and the first reference waveform in association with each movement method.

  When this modification is adopted, a process for specifying the first reference waveform is executed before the process of step Sa1 is executed in the screen display process described above. Specifically, the CPU 11 of the information processing apparatus 1 determines which waveform stored in the reference waveform information DB 121 is approximate to the waveform of acceleration measured by the acceleration sensor 14, and corresponds to the waveform that is most approximated. The first reference waveform to be attached is specified. In step Sa1, the CPU 11 determines whether or not the acceleration waveform measured by the acceleration sensor 14 is included in a predetermined range centered on the identified first reference waveform.

  When this modification is adopted, the function realized by the CPU 11 is specified by the trajectory specifying unit 111 when the moving method is adopted for each moving method of the user carrying the information processing apparatus 1. The reference trajectory corresponding to the first trajectory identified by the trajectory identifying unit 111 with reference to a database that stores information indicating the trajectory of movement of the information processing apparatus 1 to be associated with information indicating the reference trajectory Is further included. In addition, the processing execution unit 112 realized by the CPU 11 uses the reference locus specified by the reference locus specifying unit as the second locus specified by the locus specifying unit 111 after the first locus is specified. When it is included in a predetermined range as a reference, a predetermined process is executed.

  In the above-described embodiment, a predetermined range based on the first reference waveform may be corrected according to the moving method of the user carrying the information processing apparatus 1. Specifically, in the reference waveform information DB 121 described above, information defining the range of the first reference waveform is stored instead of the first reference waveform, and the process of step Sa1 is executed in the screen display process described above. Before processing, a process for specifying the range of the first reference waveform may be executed.

  When this modification is adopted, the function realized by the CPU 11 includes a first reference based on the second trajectory specified before the first trajectory is specified by the trajectory specifying unit 111. A third correction unit that corrects a predetermined range based on the trajectory is further included. Further, the processing execution unit 112 realized by the CPU 11 includes the trajectory specified by the trajectory specifying unit 111 within a predetermined range based on the first reference trajectory corrected by the third correcting unit. If so, a predetermined process is executed.

  Specifically, among the error between the acceleration waveform measured by the acceleration sensor 14 and the first reference waveform and the error between the acceleration waveform and the second reference waveform, the former is smaller than the latter. In such a case, the screen may be displayed on the touch panel 13, and the screen may not be displayed on the touch panel 13 when the former is greater than or equal to the latter. Here, the error between the acceleration waveform and the reference waveform may be a weighted error obtained by dividing the square error between the two by the variance value.

  Also, a well-known method described in Shinichiro Sada, “Research for Motion Instruction to Robot Using Free Gesture”, Graduate School of Information Systems, University of Electro-Communications (unpublished) may be used.

  When this modification is adopted, the processing execution unit 112 realized by the CPU 11 includes the first error between the first locus specified by the locus specifying unit 111 and the first reference locus, and the first A predetermined process is executed when the first error is smaller than the second error among the second errors between the second trajectory and the second reference trajectory. Further, the process execution unit 112 does not execute the predetermined process when the first error is equal to or greater than the second error.
