  An embodiment of the present invention will be described with reference to the drawings. In the following description, the size, the ratio, the arrangement, and the like of each unit are merely examples, and the example of the present embodiment is not limited to the illustrated size, ratio, and arrangement.

  A control system 1 according to an example of an embodiment of the present invention includes a control device 10 and a plurality of vibration devices 20. Specifically, the control system 1 according to the present embodiment includes two vibration devices 20, a first vibration device 20a and a second vibration device 20b.

  The vibration device 20 is as illustrated in FIG. In one example of the present embodiment, the vibration device 20 includes a device main body 21 and a fixture 22 that is one of accessories.

  The vibrating device 20 is used by passing the user's index finger to little finger through the fixing tool 22 and fixing the device body 21 at a position where the device main body 21 is in contact with the base of the user's thumb. In the example of FIG. 1, the right side of the vibration device 20 is pressed against the right palm of the user to fix the vibration device 20. The size of the vibrating device 20 is such that when the user naturally grasps the device main body 21, the terminal end of the user's thumb reaches the operation unit 23 on the front side of the vibrating device 20. The user can use the vibration device 20 by holding the lower half of the device body 21 with the palm, the middle finger, the ring finger, and the little finger. However, even if the user opens his / her hand from this state, the vibrating device 20 is fixed to the user's hand by the fixture 22, so that the vibrating device 20 does not fall.

The vibration mechanism 25 operates by consuming power supplied from the rechargeable battery 24. Note that a plurality of vibration mechanisms 25 may be built in the device body 21.

  Here, FIG. 1 shows an example of the first vibration device 20a fixed to the right hand of the user. In the second vibrating device 20b, the fixture 22 and the rechargeable battery 24 are fixed to the device main body 21 left and right opposite to the first vibrating device 20a, but the device main body 21 itself may be the same type as the first vibrating device 20a. .

  The control device 10 is an information processing device that is communicatively connected to the vibration device 20, and may be, for example, a home game machine, a personal computer, or the like. Further, in the present embodiment, the control device 10 is also communicatively connected to the display device 14. As illustrated in FIG. 2, the control device 10 includes a control unit 11, a storage unit 12, and a communication unit 13.

  The control unit 11 includes a program control device such as a CPU, and executes various types of information processing according to a program stored in the storage unit 12. The specific processing contents of the control unit 11 will be described later in detail.

  The storage unit 12 is a memory device or the like, and stores a program executed by the control unit 11. This program may be provided stored in a non-transitory computer-readable non-transitory storage medium, and may be copied to the storage unit 12. The storage unit 12 also operates as a work memory of the control unit 11.

  The communication unit 13 includes a serial interface such as a USB (Universal Serial Bus) or a wireless communication interface such as Bluetooth (registered trademark). The control device 10 is communicably connected to each vibration device 20 via the communication unit 13. In particular, in the present embodiment, the communication unit 13 receives, from each of the vibration devices 20, information indicating the content of the operation performed by the user. In addition, the communication unit 13 transmits a control signal for operating the vibration mechanism 25 of each vibration device 20 according to an instruction from the control unit 11.

  Further, the communication unit 13 includes a communication interface for communicating with the display device 14 in a wired or wireless manner. The control device 10 transmits video data to be displayed by the display device 14 to the display device 14 via the communication unit 13.

  The display device 14 displays an image based on the image signal transmitted from the control device 10. For example, the display device 14 may be a device such as a head-mounted display, which is used by a user while being worn on the head.

  Hereinafter, the operation of the control unit 11 of the control device 10 will be described. In the present embodiment, the control unit 11 functionally includes an application execution unit 31, a vibration data acquisition unit 32, and a vibration control unit 33, as illustrated in FIG. These functions are realized by the control unit 11 operating according to the program stored in the storage unit 12. This program may be provided to the control device 10 via a communication network such as the Internet, or may be provided by being stored in a computer-readable information storage medium such as an optical disk.

  The application execution unit 31 is realized by the control unit 11 executing an application program such as a game. The application execution unit 31 executes various processes according to the user's operation on the vibration device 20 and the like, and displays the processing results on the screen of the display device 14. For example, the application execution unit 31 may construct a virtual space in which various virtual objects are arranged, and may present an image showing the inside to the user.

  Further, the application execution unit 31 outputs vibration data for vibrating each of the first vibration device 20a and the second vibration device 20b according to the content of the processing. This vibration data is data for instructing how to vibrate the vibration mechanism 25 built in each vibration device 20, and here is data encoding a waveform of vibration to be generated by the vibration mechanism 25. Shall be. That is, the amplitude of the waveform included in the vibration data indicates the strength of the vibration, and the frequency indicates the period of the vibration. Such vibration data may be described in a format similar to audio data. In addition, it is assumed that the vibration data includes a waveform in which vibrations of a plurality of frequencies overlap, similarly to the audio data. The vibration data output by the application execution unit 31 is stored in a buffer area secured in the storage unit 12 together with information designating which of the first vibration device 20a and the second vibration device 20b is to be instructed. Hereinafter, data for vibrating the first vibration device 20a is referred to as first vibration data, and data for vibrating the second vibration device 20b is referred to as second vibration data. FIG. 4 shows an example of a waveform represented by the first vibration data and the second vibration data.

  The vibration data acquisition unit 32 sequentially reads and acquires the vibration data stored in the buffer area by the application execution unit 31.

  The vibration control unit 33 transmits the contents of the vibration data acquired by the vibration data acquisition unit 32 to each vibration device 20. Each of the vibration devices 20 generates a vibration corresponding to a waveform represented by the vibration data by operating the vibration mechanism 25 based on the vibration data. Thereby, the vibration device 20 can be vibrated according to the situation of the game or the like executed by the application execution unit 31, and the vibration can be presented to the left and right hands of the user.

  Further, in the present embodiment, the vibration control unit 33 executes a correction process for correcting the intensity of vibration on at least one of the first vibration data and the second vibration data as necessary. This correction process is performed when the vibration of the other vibration device 20 is started while the vibration of the other vibration device 20 is present. This is a correction process for weakening to. This is because when one of the vibrating devices 20 is vibrating while the other vibrating device 20 also vibrates, it is difficult for the user to notice the occurrence of a new vibration as it is.

  Hereinafter, of the two vibrations, the vibration started first is referred to as a first vibration, and another vibration generated later in the middle of the first vibration is referred to as a second vibration. That is, the second vibration is a vibration started after the start of the first vibration and before the end of the first vibration. In the following, for convenience of description, the first vibration is a vibration presented by the first vibration device 20a based on the first vibration data, and the second vibration is a second vibration device based on the second vibration data. It is assumed that the vibration is presented by 20b. However, conversely, the preceding first vibration may be the vibration of the second vibration device 20b, and the second vibration generated later may be the vibration of the first vibration device 20a.

  The vibration control unit 33 performs a correction to relatively weaken the intensity of the vibration in the correction target period among the first vibrations represented by the first vibration data. Specifically, this correction may be a correction for reducing the amplitude of the waveform of the vibration included in the correction target period. Here, the correction target period is a part of the entire period in which the first vibration is presented, including a period overlapping with the period in which the second vibration is presented. Subsequently, the vibration control unit 33 transmits the corrected vibration data (hereinafter, referred to as corrected vibration data) to the first vibration device 20a, and causes the vibration mechanism 25 of the first vibration device 20a to execute the corrected first vibration. . In addition, the second vibration data is transmitted to the second vibration device 20b, and the vibration mechanism 25 of the second vibration device 20b executes the second vibration.

  In the example of FIG. 4, the application execution unit 31 outputs vibration data instructing to start the first vibration from time t0 and to start the second vibration from time t1. After time t1, both the first vibration device 20a and the second vibration device 20b vibrate. In the example of this figure, the period T is determined as the correction target period, and the corrected vibration data is generated such that the first vibration during that period is weakened. Thereby, it is possible for the user to easily recognize the second vibration generated within the correction target period.

  In the above description, the vibration control unit 33 performs the correction process on the first vibration data to reduce the amplitude of the first vibration included in the correction target period. The correction process may be performed on the two vibration data. In this case, the vibration control unit 33 corrects the second vibration data so as to increase the amplitude of the second vibration included in the correction target period, and generates corrected vibration data. Even with such correction, the intensity of the first vibration in the correction target period can be made relatively weaker than that of the second vibration. Further, the vibration control unit 33 may execute the correction processing for reducing the amplitude of the first vibration and the correction processing for increasing the amplitude of the second vibration together.

  Here, a specific example of a method in which the vibration control unit 33 determines the correction target period will be described. For example, the vibration control unit 33 may set the period from the start timing of the second vibration until a predetermined time elapses as the correction target period.

  Alternatively, the vibration control unit 33 may analyze the waveform of the second vibration included in the second vibration data and determine the correction target period. Specifically, the vibration control unit 33 specifies, among the waveforms of the second vibration, an impact period in which the amplitude is particularly larger than a predetermined value, and determines a correction target period so as to include the period. The vibration control unit 33 divides, for example, the generation period of the second vibration into short unit times, and calculates the root mean square of the amplitude included in each unit time. Then, when the calculated root-mean-square is continuous for a unit time exceeding a given threshold, the continuous period is specified as an impact period. In FIG. 4, the correction target period is determined so as to include the impact period specified as described above. The impact period is a period after the start of the second vibration until the amplitude of the waveform becomes smaller than a given threshold (that is, a period until the first unit time when the root mean square of the unit time becomes smaller than the threshold). It may be. As described above, by including the period in which the amplitude of the second vibration is large in the correction target period, the user can more easily recognize that the second vibration is occurring.

  Alternatively, the vibration control unit 33 may extract only a waveform of a specific frequency from the second vibration data, and determine the correction target period based on the magnitude of the amplitude. For example, the vibration control unit 33 extracts a waveform in a predetermined frequency band including a resonance frequency of the vibration mechanism 25 (a frequency at which the vibration mechanism 25 vibrates most efficiently), and impacts a period in which the amplitude exceeds a given threshold. Specify as a period. In addition, the vibration control unit 33 extracts only a waveform having a frequency equal to or lower than a predetermined frequency from the second vibration data by low-pass filtering, and specifies a period in which the amplitude of the extracted waveform exceeds a given threshold as an impact period. May be. Also in these examples, the vibration control unit 33 may evaluate whether or not the magnitude of the amplitude exceeds a given threshold using the root mean square per unit time.

  In the above description, the impact period is specified by the vibration control unit 33 analyzing the waveform included in the vibration data output from the application execution unit 31 in real time. However, when the waveform of the vibration data specified by the application execution unit 31 is known in advance, the vibration control unit 33 stores in the storage unit 12 the information of the impact period obtained by analyzing the waveform in advance. It may be.

  As a specific example, each of a plurality of types of vibration patterns is prepared in advance as candidate vibration data, and information on an impact period obtained by analyzing a waveform included in each candidate vibration data is also stored in the storage unit 12 in advance. Shall be When it is desired to vibrate each of the vibration devices 20 in accordance with the progress of the process, the application execution unit 31 outputs, as vibration data, information specifying any of the plurality of candidate vibration data, together with information specifying the target vibration device 20. . The vibration control unit 33 determines the correction target period with reference to the information on the impact period associated with the candidate vibration data designated as the second vibration. Then, correction is performed on the candidate vibration data designated as the first vibration to weaken the vibration during the determined correction target period. Thus, the intensity of the first vibration during the impact period of the second vibration can be reduced without executing the process of specifying the impact period in real time.

  According to the control system 1 according to the embodiment of the present invention described above, when vibrations are presented to both the left and right hands of the user at the same time, the user can easily recognize the respective vibrations.

  In the above description, the user wears the vibrating devices 20 one by one on the left and right hands, and the left and right vibrating devices 20 present the vibration at the same time. However, embodiments of the present invention are not limited to this. For example, when one vibration device 20 has a plurality of built-in vibration mechanisms 25 and the vibration data obtaining unit 32 obtains vibration data for causing each of these vibration mechanisms 25 to vibrate at the same time, the vibration control is also performed. The unit 33 may similarly perform the correction of the vibration data.

  Further, even when a plurality of pieces of vibration data for vibrating the same vibration mechanism 25 are obtained, the vibration control unit 33 may perform the same correction. Specifically, the application execution unit 31 may continuously output a plurality of pieces of vibration data for vibrating the same vibration mechanism 25 depending on the processing content. Further, even when a plurality of different application programs are executed in parallel, these application programs may output vibration data for vibrating the same vibration mechanism 25 independently of each other at the same time. In such a case, the vibration control unit 33 combines waveforms included in a plurality of pieces of vibration data specifying the same vibration mechanism 25 and generates combined vibration data for causing the vibration mechanism 25 to vibrate. At this time, the vibration control unit 33 sets the period in which the preceding first vibration overlaps with the subsequent second vibration as the correction target period, and sets the first vibration in the correction target period to be relatively similar to the processing described above. The correction is made to make it weaker. Then, combined vibration data obtained by correcting the waveform of the first vibration and vibration data representing the waveform of the second vibration are combined to generate combined vibration data for causing the vibration mechanism 25 to vibrate. Accordingly, even when instructions for generating a plurality of vibrations compete with one vibration mechanism 25, the user can easily recognize each of the plurality of vibrations.

  In the above description, the vibration data is data obtained by encoding the waveform of the vibration. However, the vibration data may be data specifying the content of the vibration by the vibration mechanism 25 in another data format. As an example, the vibration data may be data that specifies the strength and length of the vibration by numerical values or the like. Also in this case, the vibration control unit 33 may specify the correction target period so as to include a period in which the intensity of the second vibration exceeds a given threshold. Further, by performing a correction process of changing a numerical value designating the vibration intensity, the intensity of the first vibration in the correction target period may be relatively weakened.

  Further, in the above description, the vibration device 20 is a device of a type that is attached to the palm of a user's hand using the fixture 22, but is not limited to this, and is a device of a type that is gripped and used by the user's hand. It may be a device that can be attached to a place other than the palm. Further, here, the vibration device 20 is an operation device that accepts a user's operation input. However, the vibration device 20 is not limited to such a device, and is used only for presenting vibration to the user. Or a device used for other purposes.

  In the above description, the control device 10 independent of the vibration device 20 performs the correction for relatively weakening one of the plurality of vibrations. However, the present invention is not limited to this. When one vibration device 20 receives an instruction to generate a plurality of vibrations from the outside, a microcomputer or the like built in the vibration device 20 performs one of the operations for a period in which the plurality of vibrations compete. It is also possible to make a correction to relatively weaken the vibration of. In this case, the vibration device 20 itself functions as the control device according to the embodiment of the present invention.
