  Next, the configuration of the vibration generating unit 37 will be described with reference to FIG. FIG. 3 is a block diagram showing an example of the configuration of the vibration generating unit 37. As shown in FIG.

  In FIG. 3, the vibration generation unit 37 includes a codec unit 371, an amplification unit 372, and an actuator (vibrator) 373.

  The codec unit 371 obtains the vibration control signal output from the control unit 31, performs predetermined decoding processing, generates an analog vibration signal, and outputs the analog vibration signal to the amplification unit 372. For example, when the actuator 373 generates a vibration, a vibration control signal (for example, a vibration control signal CS) for controlling the vibration is output from the control unit 31. In this case, the codec unit 371 decodes the vibration control signal output from the control unit 31 to generate an analog vibration signal (for example, an analog vibration signal AS) for causing the actuator 373 to generate a vibration, and an amplification unit. Output to 372.

  The amplification unit 372 amplifies the analog vibration signal output from the codec unit 371 to generate a drive signal for driving the actuator 373, and outputs the drive signal to the actuator 373. For example, the amplification unit 372 increases the amplitude change of the current / voltage of the analog vibration signal (for example, the analog vibration signal AS) output from the codec unit 371, and generates a drive signal (for example, the drive signal DS). , To the actuator 373.

  The actuator 373 drives the main body of the information processing device 3 to vibrate according to the drive signal by driving according to the drive signal output from the amplification unit 372. For example, the actuator 373 is provided at the center of the display screen of the display unit 35, as shown in FIG. Here, any method may be used as a method of causing the actuator 373 to vibrate the main body of the information processing device 3. For example, the actuator 373 generates vibration by a method of generating vibration by an eccentric motor (ERM: Eccentric Rotating Mass), a method of generating a vibration by a linear vibrator (LRA: Linear Resonant Actuator), or a piezoelectric (piezoelectric) element. It may be a configuration using a method of As long as the drive signal output from the amplification unit 372 is generated according to the method of causing the actuator 373 to generate vibration, various types of vibration may be applied to the user of the information processing apparatus 3 regardless of the type of actuator.

  In the above description, the analog vibration signal generated by the codec unit 371 is amplified to generate a drive signal for driving the actuator 373. However, the codec unit 371 outputs the drive signal to the amplification unit 372 The signal may be a digital signal. For example, when the actuator 373 is driven by pulse width modulation (PWM) control, the codec unit 371 may generate a pulse signal for turning on / off the actuator 373. In this case, the signal output from the codec unit 371 to the amplification unit 372 is a digital vibration signal whose driving is controlled using a pulse wave, and the amplification unit 372 amplifies the digital vibration signal.

  Next, before describing the specific processing performed by the information processing device 3, an outline of the processing performed in the information processing device 3 will be described using FIGS. In the following description, processing when playing a game in which the virtual object OBJ moves in the display screen of the display unit 35 is used as an example of information processing performed in the information processing device 3. FIG. 4 is a diagram showing an example in which the main body of the information processing apparatus 3 vibrates and sound is output when the virtual object OBJ displayed on the display screen of the display unit 35 moves. FIG. 5 is a diagram for describing an example of a process of generating a vibration control signal based on the acquired vibration data. FIG. 6 is a diagram for describing an example of a process of generating a vibration control signal based on vibration data acquired for each frequency band.

  In the example shown in FIG. 4, a virtual object OBJ moving in the virtual space is displayed on the display screen of the display unit 35. The virtual object OBJ moves in the virtual space according to the user operation or automatically and is displayed on the display screen of the display unit 35. Specifically, the virtual object OBJ is a sphere that rolls and moves on a plate surface installed in the virtual space.

  In response to the virtual object OBJ rolling and moving on the plate surface in the virtual space, a sound is output from the information processing device 3 and the main body of the information processing device 3 vibrates. For example, a speaker (voice output unit 36) provided in the main body of the information processing device 3 outputs a voice in which a virtual object OBJ displayed on the display screen of the display unit 35 and moving is a sound source. Further, an actuator 373 provided in the main body of the information processing device 3 causes a vibration that occurs when the virtual object OBJ is rolled and moved. In the present embodiment, vibration data for generating a vibration control signal for generating the vibration is acquired from another device. Then, the information processing device 3 generates a vibration control signal for driving and controlling the actuator 373 based on the acquired vibration data.

  Next, an example of a process of generating a vibration control signal will be described with reference to FIG. As described above, the vibration control signal for controlling the vibration generated by the actuator 373 is generated based on the vibration data transferred from another device. In this embodiment, AMFM code data transferred from another device is received as vibration data, and an AMFM wave generated based on the AMFM code data is used as a vibration control signal. Here, AM code data indicates data representing amplitude modulation of vibration, FM code data indicates data representing frequency modulation of vibration, and AMFM code data indicates amplitude modulation and frequency modulation of vibration. Shows data representing both Also, the AMFM wave indicates a vibration waveform that is amplitude-modulated and frequency-modulated based on AMFM code data.

  As shown in FIG. 5, AMFM code data is transferred from another device every fixed update period that modulates the vibration, and functions as a vibration amplitude and frequency update command. Then, AMFM code data is decoded using a predetermined coding table to extract AM information and FM information. Here, AM information is information which shows the amplitude of the vibration after updating on the basis of the amplitude of the vibration before updating. By analyzing such AM information for each update period, it is possible to obtain information as shown in FIG. 5 that modulates vibration amplitude in time series on the basis of a predetermined amplitude. Moreover, FM information is information which shows the amplitude of the vibration after update on the basis of the frequency of the vibration before update. By analyzing such FM information at each update period, it is possible to obtain information as shown in FIG. 5 which modulates the vibration frequency in time series with reference to a predetermined frequency. An example of a coding table used for decoding processing and decoding of AMFM code data will be described later.

  Next, a frequency modulation sine wave (FM wave) is generated from the FM information. Here, the FM wave is a sine wave as shown in FIG. 5 which is displaced at a frequency corresponding to the FM information acquired at each update period.

  Then, an AMFM wave is generated by multiplying the AM information by the FM wave. Here, the AMFM wave has a waveform as shown in FIG. 5 which is displaced at a frequency corresponding to the FM information acquired at each update period and at an amplitude corresponding to the AM information acquired at each update period. . By generating a vibration control signal based on the AMFM wave thus generated, the actuator 373 can be vibrated at the frequency and amplitude indicated by the AMFM wave.

  By transmitting vibration data by such an AMFM transmission method, the following effects can be expected. As a first effect, when transmitting vibration data as compared with a method of transmitting vibration data as it is, a method of transmitting with a reduced sampling rate of vibration data, and a method of compressing vibration data by a predetermined method and transmitting Data communication volume can be reduced. As a second effect, since the processing load for decoding the transmitted AMFM code data is relatively low, decoding processing can be performed in real time to connect to vibration control of the actuator 373. As a third effect, since the parameters for controlling the vibration become the frequency and the amplitude, the work of generating the vibrating material can be simplified. As a fourth effect, by setting the vibration frequency controlled by the AMFM transmission method in the vicinity of the resonance frequency of the actuator 373, relatively strong (power efficient) vibration can be given to the user.

  Further, in the above-described AMFM transmission scheme, AMFM code data may be transmitted for each frequency band. Hereinafter, with reference to FIG. 6, a process of generating a vibration control signal based on vibration data acquired for each frequency band will be described.

  As shown in FIG. 6, AMFM code data in this embodiment is transferred from another device for each frequency band at a constant update cycle for modulating the vibration, and functions as an amplitude and frequency update command of the vibration for each frequency band. Do. For example, in the example shown in FIG. 6, the update cycle of AMFM code data for frequency band A, which is a low frequency band, and AMFM code data for frequency band B, which is a high frequency band, is the same or different. Every other device has sent it.

  The AMFM code data for the frequency band A is decoded using a predetermined coding table in the same manner as the processing described above, whereby AM information and FM information are extracted, and an FM wave is generated from the FM information. Ru. Then, by multiplying AM information for the frequency band A by the FM wave, an AMFM wave for the frequency band A is generated.

  On the other hand, AMFM code data for the frequency band B is also decoded using a predetermined coding table in the same manner as the above-described processing to extract AM information and FM information, and FM waves are extracted from the FM information. It is generated. Then, by multiplying the FM wave with AM information for the frequency band B, an AMFM wave for the frequency band B is generated.

  Then, a synthetic wave is generated by adding the AMFM wave intended for the frequency band A and the AMFM wave intended for the frequency band B. Since the combined wave has both AMFM information for frequency band A and AMFM information for frequency band B, it is displaced based on frequency information and amplitude information for a plurality of frequency bands as shown in FIG. It has a waveform as shown. By generating a vibration control signal based on the generated synthetic wave, the actuator 373 can be vibrated at the frequency and amplitude indicated by the synthetic wave.

  By transmitting vibration data by the AMFM transmission method for each of a plurality of such frequency bands, it is possible to transfer frequency changes and amplitude changes for each of the plurality of frequency bands, so that vibration can be transmitted more accurately from other devices. be able to. Therefore, it becomes possible to transmit vibration data without deteriorating the vibration feeling given to the user as compared with other transmission methods.

  Next, an example of frequency band division at the time of transferring AMFM code data for each of a plurality of frequency bands will be described. As an example, it is conceivable to set a plurality of frequency bands for transferring AMFM code data in accordance with the characteristics of human tactile sense to which vibration is given. Sensory receptors that receive human skin sensation are composed of Merkel's disc, Meissner's body, Pacini's body, Ruffini's terminal, etc., and respond to vibrations in their specific frequency bands. Also, the vibration that can be felt by humans is considered to be a vibration in the frequency band of 0 to 1000 Hz. Here, among the human sensory receptors, two are Meissner's body and Pachiny's body that alone produce vibration sensation, and the Meissner's body responds to low-frequency vibration (for example, 10 to 200 Hz), Pacinian bodies respond to high frequency vibrations (e.g. 70-1000 Hz). Therefore, it is conceivable to respectively transmit AMFM code data to the low frequency band (10-200 Hz) for the Meissner body and the high frequency band (70-1000 Hz) for the Pacinian body. .

  The frequency to be used as a reference (hereinafter referred to as the center frequency) for each frequency band is set, for example, such that the ratio of the center frequency is 1.5 or more, and the vibration device (the actuator 373 in the above embodiment) (E.g., around the resonance frequency of the vibrating device). As described above, by mainly using the frequency band in which the vibration device easily vibrates, the amount of feeling of the vibration felt by the user with respect to the power consumed when generating the vibration is increased. Can make you feel. In the case where the vibration device has ideal frequency characteristics (flat characteristics), only the characteristics of the human sensory receptor described above need to be considered, so the center frequency is, for example, 40 Hz in the low frequency band. It may be set near to 250 Hz in the high frequency band.

  In the above description, the frequency band for transferring AMFM code data is divided according to the response frequency band of the sensory receptor that receives human skin sensation, but the frequency is determined based on other characteristics. The bandwidth may be divided. For example, the frequency band for transferring AMFM code data may be divided according to the characteristic frequency of the actuator to be vibrated. As an example, when the actuator to be vibrated has a plurality of resonance frequencies, a plurality of frequency bands may be set to include at least one of the resonance frequencies, and AMFM code data may be transferred for each of the frequency bands. Good.

  Also, AMFM code data may be transferred every three or more frequency bands. As an example, when it is necessary to sequentially generate vibrations in different frequency bands at extremely short time intervals, it is conceivable that the update period can not catch up with the speed at which the frequency transitions if the number of frequency bands for transferring AMFM code data is small. Specifically, when vibrations having three frequencies of 50 Hz, 150 Hz, and 450 Hz are sequentially generated at 50 ms intervals, accurate vibration can be generated by transferring AMFM code data for each of three or more frequency bands. it can. As described above, the number of frequency bands may be two if the vibration is felt only by human touch, but if the auditory stimulus is added to the touch and the vibration is felt, the number of frequency bands is controlled to three or more. Can be effective. Further, in the case of giving vibrations of a plurality of constant frequencies without changing the vibration frequency, it is desirable that the ratio of each frequency (center frequency) be a simple integer ratio. Thus, by setting the frequency to be generated to an integer ratio, it is possible to prevent the occurrence of "beating" when vibrations of two frequencies are generated simultaneously. Here, “beat” is a phenomenon in which two vibration waves having slightly different vibration frequencies interfere with each other to generate a composite wave in which the vibration amplitude changes slowly and periodically.

  Also, AMFM code data may be transferred to a single frequency band. As a first example, it may be considered to transmit AMFM code data only to a single frequency band when there is no application to generate vibrations including multiple frequency band components. As a second example, in the case of vibrating a vibrating device which is extremely biased to a certain frequency band and does not vibrate at frequencies other than only one resonance frequency belonging to the frequency band, the frequency characteristics of the vibrating device to be vibrated Transfer of AMFM code data is considered. As a third example, when priority is given to data compression efficiency when transferring AMFM code data, it is conceivable to transfer AMFM code data only to a single frequency band.

  Next, an example of the decoding process of AMFM code data will be described with reference to FIGS. 7 and 8. FIG. 7 is a diagram showing an example of a coding table used to decode AMFM code data. FIG. 8 is a diagram showing an example of the k calculation table used when calculating the value k used in the coding table.

  FIG. 7 shows a 3-bit AMFM encoding table for performing an amplitude update instruction and a frequency update instruction using a 3-bit code. In the AMFM code data decoding process, an amplitude value and frequency to be set next are set based on the amplitude value and frequency shown immediately before the update process using such an AMFM encoding table, and a predetermined sampling rate ( For example, composite waveform data is calculated at 8000 Hz). Note that although the reproduction accuracy of the synthesized waveform calculated by raising the sampling rate in the decoding process is increased, the decoding processing load is increased, so the frequency of updating AMFM code data to be described later and the reproduction accuracy of the necessary synthesized waveform. The sampling rate may be set in consideration of the balance of In the AMFM code data decoding process described below, it is determined that the initial value of the vibration amplitude is 1/4096, the minimum value of the vibration amplitude is 1/4096, the maximum value of the vibration amplitude is 1, and the vibration amplitude is 0. The zero threshold is set to 1.5 / 4096. Furthermore, in the AMFM code data decoding process described below, the initial value of the vibration frequency is set to the center frequency (for example, around 160 Hz or 320 Hz, which is the resonance frequency of the vibration device) and vibration frequency set for each frequency band. The minimum value of is 100 Hz, and the maximum value of the frequency of vibration is 1000 Hz.

  The amplitude update instruction and the frequency update instruction shown in FIG. 7 respectively indicate an amplitude value and a frequency which are set next with reference to the amplitude value and the frequency shown immediately before the update processing. The device that receives the amplitude update command and the frequency update command receives the amplitude update command and the frequency update command of the vibration value and the vibration frequency of the period until the next amplitude update command and the frequency update command are received. Update based on and set. As a first example, the vibration amplitude value and vibration frequency set based on the received amplitude update command and frequency update command are set as values immediately after reception and the vibration amplitude value and vibration frequency are updated immediately You may As a second example, the amplitude value and frequency of vibration set based on the received amplitude update command and frequency update command are set as values immediately before the next amplitude update command and frequency update command are received, The amplitude value of the oscillation and the frequency of the oscillation may be updated incrementally and / or incrementally to reach the value during the period. As a third example, the amplitude value and frequency of vibration set based on the received amplitude update command and frequency update command are intermediate values of the period until the next amplitude update command and frequency update command are received. The amplitude value of the vibration and the frequency of the vibration may be updated incrementally and / or incrementally to reach the value at an intermediate point in the period.

For example, when AMFM code data indicates code 0 (000), the amplitude value of the vibration is reset to an initial value (for example, 1/4096) and updated, and the frequency of the vibration is set to an initial value (for example, 160 or 320) It is reset and updated. When AMFM code data indicates code 1 (001), the amplitude value of vibration is updated by 2 ^0.5 times (about 1.414 times) and updated, and the frequency of vibration is 2 ^0.2 times (about 1.149 times) ) Is updated. When AMFM code data indicates code 2 (010), the amplitude value of vibration is updated by 2 ^0.5 times (about 1.414 times) and updated, and the frequency of vibration is ^2-0.2 times (about 0.871) Times) and updated. If AMFM code data indicates a numeral 3 (011), the amplitude value of the vibration is updated by ^{2 -0.3} times (approximately 0.812 times), the frequency of vibration is ^{2 0.2} times (about 1.149 Times) and updated. If AMFM code data indicating code 4 (100), the amplitude value of the vibration is updated by ^{2 -0.3} times (approximately 0.812 times), ^{2 -0.2} times the frequency of the vibration (approximately 0. It is updated 871 times). When the AMFM code data indicates code 5 (101), the amplitude value of the vibration is multiplied by 2 ^k-2 and updated, and the frequency of the vibration is kept unchanged. If the AMFM code data indicates code 6 (110), the amplitude value of the vibration is multiplied by 2 ^k and updated, and the frequency of the vibration is kept unchanged. When the AMFM code data indicates code 7 (111), the amplitude value of the vibration is updated by 2 ^{k + 2} and updated, and the frequency of the vibration is kept unchanged.

Here, the value k is set according to the amplitude value shown immediately before the updating process. For example, as shown in FIG. 8, when the amplitude value shown immediately before the update is equal to or greater than the minimum amplitude (eg, 1/4096) and less than 2 ^0.5 times the minimum amplitude, k = 2 is set. If the amplitude value shown immediately before the update is not less than 2 ^0.5 times the minimum amplitude and less than 2 ^1.5 times (about 2.828 times) the minimum amplitude, k = 1 is set. If the amplitude value shown immediately before the update is 2 ^1.5 times or more of the minimum amplitude and ^2-1.5 times (about 0.354 times) or less of the maximum amplitude (for example, 1), k is set to 0 Be done. If the amplitude value indicates the update immediately before is not more than ^{2 -0.5} times the maximum amplitude greater than ^{2 -1.5} times the maximum amplitude (approximately 0.707) is set to k = -1. When the amplitude value shown immediately before the update is greater than ^2-0.5 times the maximum amplitude and less than the maximum amplitude, k is set to -2.

  In the above-described AMFM code data decoding process, an example using a 3-bit AMFM coding table for performing an amplitude update instruction and a frequency update instruction using a 3-bit code is used, but even if the decoding process is performed using another method. Good. For example, a decoding process using a 4-bit AMFM encoding table that performs an amplitude update instruction and a frequency update instruction using a 4-bit code, a decoding process using a 2-bit AM encoding table that performs an amplitude update instruction using a 2-bit code, A decoding process using a 3 bit AM coding table that performs an amplitude update instruction using a 3 bit code can be considered. The decoding process using the 4 bit AMFM encoding table can perform 15 kinds of amplitude update instructions and frequency update instructions, so AM information and FM information are more detailed compared to the decoding process using the 3 bit AMFM encoding table It is possible to control In addition, decoding processing using the above 3 bit AM encoding table and the above 2 bit AM encoding table can be performed only for the amplitude update instruction, and as an example, the vibration frequency is a predetermined frequency (for example, the center frequency and substantially the resonance frequency of the actuator). By modulating the amplitude of a simple sine wave at a frequency around the resonance frequency). Here, in the feeling of vibration given to the user, the influence of the amplitude is generally high and the influence of the frequency tends to be low. Therefore, in the decoding process using the 3-bit AM encoding table and the 2-bit AM encoding table, it is possible to perform detailed control on the amplitude update instruction by performing vibration control focused on the amplitude and It is possible to reduce the amount of communication.

  The fundamental wave used in the decoding process using the 3 bit AM coding table and the 2 bit AM coding table does not have to be a simple sine wave having a constant frequency, but may be positive or negative values such as rectangular wave, triangular wave, sawtooth wave, etc. It may be a fundamental wave having a waveform of a repeating shape or a waveform of another shape having a constant amplitude. Moreover, the noise which has a specific frequency band component may be the said fundamental wave. For example, the fundamental wave may be formed by white noise passing through a band pass filter that passes a specific frequency band component. Further, information indicating the frequency, shape, noise type, etc. of the fundamental wave is included in AMFM code data transferred in the decoding process using the 3 bit AM coding table and the 2 bit AM coding table, and based on the information The decoding process may be performed using the fundamental wave.

The fundamental wave may be a waveform having a shape that does not repeat positive and negative values. For example, it may be a waveform that repeats a larger value and a smaller value than the reference value, and a waveform having a shape in which a positive local maximum and a local minimum of 0 or more are alternately repeated, or a local maximum of 0 or lower and a negative local minimum It may be in the form of a waveform that repeats. As an example, the waveform of the fundamental wave is
(1-cos (2πft)) / 2
The waveform may alternately repeat the maximum value of +1 and the minimum value of 0 represented by Here, f is frequency and t is time. When an FM wave is generated using such a fundamental wave, a waveform is formed which alternately repeats the maximum value of +1 and the minimum value of 0 at the frequency indicated by the FM information. Then, when an AMFM wave is generated based on the FM wave, an amplitude value between 0 and +1 indicated by the AM information is taken as a maximum value, and the maximum value and a minimum value of 0 at the frequency indicated by the FM wave. Are alternately formed.

  By using the fundamental wave of such a shape, the following effects can be expected. For example, when the actuator 373 is configured by a linear vibration motor, a spring is provided to the linear vibration motor. When a positive voltage is applied to the linear vibration motor, the position of the internal weight moves in the direction opposite to the force of the spring, and the reaction force of the spring causes the weight to return to the original position. It will be in the state. Therefore, since the weight returns to the original position only by setting the applied voltage to 0 without applying a negative voltage, it is possible to generate a vibration with sufficient strength only by applying a positive voltage. It is possible to obtain an effect in terms of power efficiency when driving the linear vibration motor.

  In addition, when AMFM code data is acquired for each of a plurality of frequency bands and decoding processing is performed, AMFM code is generated with a lower update frequency than a mode in which AMFM code data is acquired for a single frequency band and decoding processing is performed Data may be acquired to generate vibration data. For example, when AMFM code data is acquired for a single frequency band and AMFM code data is acquired from another device and decoded at a cycle of 400 Hz in a mode of decoding processing, AMFM is generated for each of two frequency bands. In the aspect of acquiring code data and performing decoding processing, AMFM code data may be acquired and decoded from another device in a cycle of 200 Hz. When AMFM code data is acquired for each of a plurality of frequency bands and decoded, the AMFM code data may be acquired and decoded at an update frequency different for each frequency band. As an example, it is conceivable to set the update frequency for the high frequency band relatively less than the update frequency for the low frequency band. As another example, it is conceivable to transfer and decode AMFM code data at a different update frequency for each frequency band according to the magnitude of vibration amplitude occurring for each frequency band. For example, when the magnitude of the vibration amplitude occurring in the first frequency band is larger than the magnitude of the vibration amplitude occurring in the second frequency band, the update frequency relatively frequently from other devices in the first frequency band The AMFM code data is acquired and decoded at a cycle of, for example, 400 Hz, and AMFM code data is acquired at a relatively low update frequency (for example, a cycle of 200 Hz) from other devices in the second frequency band. It is conceivable to perform decoding processing. In addition, if the magnitude of the vibration amplitude occurring in the first frequency band is equal to the magnitude of the vibration amplitude occurring in the second frequency band, and both are larger than the predetermined threshold, the first frequency band and the first frequency band It is conceivable to acquire and decode AMFM code data from other devices in frequency bands of 2 with relatively high update frequency (for example, a cycle of 400 Hz). In addition, if the magnitude of the vibration amplitude occurring in the first frequency band is equal to the magnitude of the vibration amplitude occurring in the second frequency band, and both are smaller than the predetermined threshold, the first frequency band and the first frequency band It is conceivable to acquire and decode AMFM code data from other devices in frequency bands of 2 with relatively low update frequency (for example, a cycle of 200 Hz).

  Next, an example of processing for encoding AM code data in a device serving as a transfer source of AM code data (that is, code data for which only an amplitude update instruction is performed) and processing for receiving and decoding the AM code data will be described. Do. First, in the transfer source device, original vibration data (vibration waveform) to be transferred is prepared. Then, when the transfer source device transfers AM code data for each of a plurality of frequency bands in order to transmit the vibration data to another device, each frequency band is passed through a band pass filter for each of the frequency bands. Each component vibration data is generated. As an example, in the case of transferring AM code data corresponding to a first frequency band having a center frequency of 160 Hz and AM code data corresponding to a second frequency band having a center frequency of 320 Hz, the original vibration data is Processing is performed using a band pass filter that passes 1 frequency band component to generate vibration data of a first frequency band component, and a band pass filter that passes original vibration data to a second frequency band component Vibration processing of the second frequency band component is generated by processing. Then, using the envelope waveform of the vibration waveform indicating the vibration data of the first frequency band component, the AM code of the first frequency band component is encoded by encoding the envelope of the envelope using a predetermined coding table. Generate data. Also, using the envelope waveform of the vibration waveform indicating the vibration data of the second frequency band component, AM code data of the second frequency band component is encoded by encoding the outline of the envelope using the above encoding table. Generate Then, the device serving as the transfer source of the AM code data transmits the generated AM code data of the first frequency band component and the AM code data of the second frequency band component to another device at every update period. Note that the process of encoding the AM code data described above may be prepared in advance by analyzing in the off-line process in the transfer source device.

  On the other hand, in the apparatus that has received the AM code data for each frequency band, the AM information of the first frequency band component is extracted using the encoding table, and the AM information of the first frequency band component and the first frequency An AM wave corresponding to the first frequency band component is generated by multiplying the band component with the fundamental wave (for example, a sine wave of 160 Hz). In the above apparatus, the AM information of the second frequency band component is extracted using the encoding table, and the AM information of the second frequency band component and the fundamental wave of the second frequency band component (for example, 320 Hz) An AM wave corresponding to the second frequency band component is generated by multiplying with a sine wave). Then, in the above-described apparatus, a synthetic wave is generated by adding the AM wave corresponding to the first frequency band component and the AM wave corresponding to the second frequency band component, and the actuator is driven based on the synthetic wave. Generate a vibration control signal to control. The process of decoding the AM code data and controlling the vibration of the actuator may be performed in real time according to the acquisition of the AM code data from the transfer source device.

  Next, details of data output processing performed in a device that is a transfer source of AMFM code data (that is, code data for which an amplitude update instruction and a frequency update instruction are performed) will be described. In the following description, code data transmission processing is used as an example of data output processing. First, with reference to FIG. 9, main data used in the code data transmission process of the transfer source device will be described. FIG. 9 is a diagram showing an example of main data and a program stored in the storage unit of the transfer source device when performing code data transmission processing.

  As shown in FIG. 9, the original vibration data Da, frequency analysis processing data Db, envelope processing data Dc, coding processing data Dd, AMFM code data De, etc. are stored in the data storage area of the storage unit of the transfer source device. It is memorized. In addition to the data shown in FIG. 9, the storage unit of the transfer source device may store data required for processing, such as data used in an application to be executed. Further, various program groups Pa constituting a code data transmission program are stored in the program storage area of the storage unit of the transfer source device.

  The original vibration data Da is original vibration data (vibration waveform) prepared in advance in the transfer source device, and is vibration data as a source of processing for generating AMFM code data.

  The frequency analysis processing data Db is data indicating a frequency included in the vibration data obtained by frequency analysis of the original vibration data (vibration waveform).

  The envelope processing data Dc is data indicating an envelope waveform of a vibration waveform indicating original vibration data or vibration data of a predetermined frequency band component.

  The encoding processing data Dd is data used when encoding using AM information (envelope envelope shape) and / or FM information, and is data including, for example, encoding table data used for encoding processing, etc. .

  The AMFM code data De is data indicating AMFM code data obtained by encoding AM information (envelope envelope shape) and / or FM information.

  Next, with reference to FIG. 10, the details of the code data transmission process which is an example of the data output process performed in the transfer source device will be described. FIG. 10 is a flowchart showing an example of the code data transmission process performed in the transfer source device. Here, in the flowchart shown in FIG. 10, among the processes in the transfer source device, the process of generating and transmitting AMFM code data based on the original vibration data is mainly described, and it is not directly related to these processes. Detailed description of other processing is omitted. Further, in FIG. 10, each step executed by the control unit of the transfer source device is abbreviated as “S”.

  The CPU of the control unit of the transfer source device initializes the memory and the like of the storage unit of the transfer source device, and reads the code data transmission program from the program storage unit of the transfer source device into the memory. Then, execution of the code data transmission program is started by the CPU. The flowchart shown in FIG. 10 is a flowchart showing a process performed after the above process is completed.

  Note that the processing of each step in the flowchart shown in FIG. 10 is merely an example, and the processing order of each step may be switched if similar results can be obtained, and in addition to the processing of each step And / or alternatively, another process may be performed. Further, in the present embodiment, although the processing of each step of the flowchart is described as being executed by the control unit (CPU) of the transfer source device, the CPU executes the processing of some steps in the flowchart, The processing of the other steps may be executed by a processor or a dedicated circuit other than the CPU, and the processing of all the steps in the flowchart may be executed by a processor or a dedicated circuit other than the CPU.

  In FIG. 10, the control unit of the transfer source device performs transmission setting (step 61), and proceeds to the next step. For example, the control unit of the transfer source device performs initial setting for transmitting AMFM code data to another device (for example, the information processing device 3). As an example, the control unit of the transfer source apparatus encodes the number of frequency bands transmitting AMFM code data, the range of each frequency band, the cycle of transmitting AMFM code data, the encoding table used for encoding, etc. Set to Dd and initialize each parameter.

  Next, the control unit of the transfer source device acquires original vibration data for which AMFM code data is to be generated from the storage unit of the transfer source device (step 62), and proceeds to the next step. For example, the control unit of the transfer source device extracts vibration data to be generated as AMFM code data from a plurality of vibration data stored in advance in the storage unit of the transfer source device, and the extracted vibration data is Store as original vibration data Da.

  Next, the control unit of the transfer source device initializes a temporary variable N used in the process to 1 (step 63), and the process proceeds to the next step.

  Next, the control unit of the transfer source device performs band pass filter processing according to the Nth frequency band (step 64), and proceeds to the next step. For example, the control unit of the transfer source device sets a band pass filter for passing the Nth frequency band component, and uses the band pass filter to store vibration data (vibration waveform) stored as original vibration data Da. The processing generates vibration data from which frequency band components other than the Nth frequency band component have been removed.

  Next, the control unit of the transfer source device performs frequency analysis on the vibration data of the Nth frequency band component generated in step 64 (step 65), and the process proceeds to the next step. For example, the control unit of the transfer source device analyzes the frequency change of the vibration included in the vibration data by performing frequency analysis of the vibration data of the Nth frequency band component, and the data indicating the analysis result is It stores as analysis processing data Db.

  Next, the control unit of the transfer source device generates FM information in the Nth frequency band component based on the frequency analysis processing data Db corresponding to the Nth frequency band component (step 66), and the next step Proceed to For example, based on the frequency analysis result obtained in step 65, the control unit of the transfer source device may perform FM information (for example, as shown in FIGS. 5 and 6) indicating a frequency change in vibration data of the Nth frequency band component. FM information shown) is generated.

  Next, the control unit of the transfer source device generates the envelope waveform of the vibration data of the Nth frequency band component generated in step 64 (step 67), and the process proceeds to the next step. For example, the control unit of the transfer source device generates a signal taking the envelope of the vibration data (vibration waveform) of the Nth frequency band component generated in step 64, and processes the data indicating the signal as envelope processing data Store as Dc. In the envelope processing, the movement maximum value (maximum value in each moving section during movement) of vibration data of the Nth frequency band component (for example, waveform data in which the horizontal axis represents time and the vertical axis represents amplitude) The envelope may be calculated, the envelope of the section maximum value in each predetermined section of the vibration data may be calculated, or a curve passing the maximum value of the amplitude in the vibration data may be calculated.

  Next, the control unit of the transfer source device generates AMFM code data by encoding the envelope of the envelope waveform generated at step 67 and the FM information (step 68), and the processing is performed to the next step. Advance. For example, the control unit of the transfer source device calculates the amount of change in amplitude in the Nth frequency band component for each cycle of transmitting AMFM code data based on the outline of the envelope waveform generated in step 67. Further, the control unit of the transfer source device calculates the amount of change in frequency in the Nth frequency band component for each cycle of transmitting AMFM code data based on the FM information generated in step 66. Then, the control unit of the transfer source apparatus encodes the calculated variation amount of amplitude and variation amount of frequency based on the encoding table used for encoding, thereby transmitting AMFM code data in each cycle. AMFM code data corresponding to the Nth frequency band component is generated, and the AMFM code data is stored as AMFM code data De corresponding to the Nth frequency band component.

  Next, the control unit of the transfer source device determines whether or not the encoding process for each frequency band is completed for the original vibration data acquired in step 62 (step 69). Then, the control unit of the transfer source device advances the process to step 70 when there remains a frequency band for which the encoding process has not been completed. On the other hand, when there is no frequency band for which the encoding process has not ended, the control unit of the transfer source device advances the process to step 71.

  In step 70, the control unit of the transfer source device adds 1 to the temporary variable N to update the temporary variable N, and the process proceeds to step 64.

  On the other hand, in step 71, the control unit of the transfer source apparatus transmits AMFM code data corresponding to the cycle to the transfer destination apparatus (for example, the information processing apparatus 3) every cycle of transmitting AMFM code data, and the flowchart End processing by.

  The process of encoding AMFM code data described above (that is, the process of steps 61 to 69) may be processed in advance in the offline process in the transfer source device and stored as AMFM code data De. It may be performed in real time according to the request from the transfer destination device.

  Next, the details of vibration signal generation performed in the information processing device 3 which is the transfer destination of AMFM code data will be described. In the following description, code data reception processing is used as an example of the vibration signal generation processing. First, main data used in the code data reception process of the information processing device 3 will be described with reference to FIG. FIG. 11 is a diagram showing an example of main data and a program stored in the storage unit 32 of the information processing device 3 when code data reception processing is performed.

  As shown in FIG. 11, in the data storage area of the storage unit 32, received data Dm, AM information data Dn, FM information data Do, FM wave data Dp, AMFM wave data Dq, combined wave data Dr, and vibration control signal Data Ds and the like are stored. In addition to the data shown in FIG. 11, the storage unit 32 may store data necessary for processing, such as data used in an application to be executed. Further, in the program storage area of the storage unit 32, various program groups Pb constituting the code data receiving program are stored. For example, the various program groups Pb include a reception program for receiving AMFM code data, a decoding program for decoding AMFM code data, a vibration control signal generation program for generating a vibration control signal, and the like.

  The received data Dm is data received from another device (for example, the transfer source device described above).

  The AM information data Dn is data indicating AM information extracted from AMFM code data transferred from another device. The FM information data Do is data indicating FM information extracted from AMFM code data transferred from another device.

  The FM wave data Dp is data indicating a frequency modulation sine wave (FM wave) generated from the FM information. The AMFM wave data Dq is data indicating an AMFM wave generated by multiplying AM information by an FM wave.

  The combined wave data Dr is data indicating a combined wave generated by adding together AMFM waves generated for each frequency band. The vibration control signal data Ds is data for performing drive control of the actuator 373, which is generated based on the composite wave. For example, the vibration control signal data Ds is data indicating a vibration control signal (vibration control signal CS; see FIG. 3) to be output from the control unit 31 to the vibration generating unit 37.

  Next, with reference to FIG. 12, the details of the code data receiving process which is an example of the vibration signal generation process performed in the information processing device 3 will be described. FIG. 12 is a flowchart showing an example of the code data reception process performed by the information processing device 3. Here, in the flowchart shown in FIG. 12, among the processes in the information processing apparatus 3, the process of receiving AMFM code data from another apparatus and generating a vibration control signal will be mainly described, and these processes may be directly related. Detailed description of other processes that are not performed will be omitted. Moreover, in FIG. 12, each step which the control part 31 of the information processing apparatus 3 performs is abbreviated as "S".

  The CPU of the control unit 31 of the information processing device 3 initializes the memory and the like of the storage unit 32 and reads the code data receiving program from the program storage unit 33 of the information processing device 3 into the memory. Then, execution of the code data receiving program is started by the CPU. The flowchart shown in FIG. 12 is a flowchart showing a process performed after the above process is completed.

  Note that the processing of each step in the flowchart shown in FIG. 12 is merely an example, and if similar results can be obtained, the processing order of each step may be exchanged, and in addition to the processing of each step And / or alternatively, another process may be performed. Further, in the present embodiment, the processing of each step in the flowchart is described as being executed by the control unit 31 (CPU) of the information processing device 3, but the CPU executes the processing of some steps in the flowchart. The processing of the other steps may be executed by a processor or a dedicated circuit other than the CPU, and the processing of all the steps in the flowchart may be executed by a processor or a dedicated circuit other than the CPU.

  In FIG. 12, the control unit 31 performs reception setting (step 81), and proceeds to the next step. For example, the control unit 31 performs initial setting for receiving AMFM code data from another device (for example, the transfer source device). As an example, the control unit 31 sets the number of frequency bands for receiving AMFM code data, the range of each frequency band, the cycle for receiving AMFM code data, the coding table used for decoding processing, etc. Set The parameters to be set in the reception setting may be set based on the information described in the reception data received from another device.

  Next, the control unit 31 waits for reception of code data (for example, AMFM code data) from another device (step 82). When the control unit 31 receives code data from another device, the control unit 31 stores the received data as reception data Dm, and advances the process to step 83.

  In step 83, the control unit 31 decodes the AMFM code data received in step 82 to extract AM information, and the process proceeds to the next step. For example, the control unit 31 sets a frequency band to be processed, extracts AMFM code data corresponding to the frequency band from the data received in the above step 82, and based on the set coding table, The AM information of the frequency band component is taken out and stored as AM information data Dn. Here, the method of extracting AM information is the same as that described with reference to FIGS. 5 to 8. In addition, when the amplitude value calculated as AM information is smaller than the minimum value (for example, 1/4096) of the vibration amplitude currently preset, AM information is set to the said minimum value. In addition, when the amplitude value calculated as AM information is larger than the maximum value (for example, 1) of vibration amplitudes set in advance, the AM information is set to the maximum value.

  Next, the control unit 31 decodes the AMFM code data received in step 82 to extract FM information (step 84), and proceeds to the next step. For example, the control unit 31 extracts AMFM code data corresponding to the frequency band set as the processing target from the data received in the above step 82, and the FM of the frequency band component based on the set coding table. Information is taken out and stored as FM information data Do. In addition, about the extraction method of FM information, it is the same as that of the aspect demonstrated using FIGS. 5-8. If the frequency calculated as the FM information is smaller than the minimum value (for example, 100 Hz) of the preset vibration frequency, the FM information is set to the minimum value. When the frequency calculated as the FM information is larger than the maximum value (for example, 1000 Hz) of the vibration frequency set in advance, the FM information is set to the maximum value.

  Next, the control unit 31 generates a frequency modulation sine wave (FM wave) from the FM information extracted in step 84 (step 85), and proceeds to the next step. For example, as described with reference to FIGS. 5 and 6, the control unit 31 generates a sine wave displaced at a frequency according to the FM information as an FM wave corresponding to the frequency band, and indicates the data indicating the FM wave Are stored as the FM wave data Dp.

  Next, the control unit 31 multiplies the AM information extracted in step 83 by the FM wave generated in step 85 to generate an AMFM wave (step 86), and proceeds to the next step. For example, the control unit 31 generates, as an AMFM wave corresponding to the frequency band, a vibration waveform displaced at an amplitude corresponding to the AM information extracted at step 83 at a frequency corresponding to the FM wave generated at step 85. And data indicating the AMFM wave is stored as AMFM wave data Dq. When the amplitude value of the AMFM wave is converted to the value of the vibration amplitude used in the application generating the vibration, the amplitude value of the AMFM wave may be changed by the magnification necessary for the conversion in the step 86. For example, when the vibration sample is expressed in a signed 16-bit integer type (-32768 to +32767) in the above application, the amplitude value of the AMFM wave is multiplied by 32767 and conversion is performed, and the amplitude value of the AMFM wave is zero threshold If it is smaller than (for example, 1.5 / 4096), the value of the vibration amplitude used in the application is converted to 0.

  Next, in step 82, the control unit 31 determines whether code data in another frequency band is received (step 87). Then, when code data of another frequency band is received, the control unit 31 sets another frequency band as a processing target, and advances the process to step 83 described above. On the other hand, when the code data of another frequency band is not received (when the decoding process for the code data of all frequency bands is completed), the control unit 31 sets another frequency band as a processing target. Proceed to step 83.

  In step 88, the control unit 31 adds the AMFM waves for the respective frequency bands generated in step 86 to generate a composite wave, and the process proceeds to the next step. For example, the control unit 31 stores data as synthetic wave data Dr indicating a synthetic wave generated by adding AMFM waves for the frequency band.

  Next, the control unit 31 generates a vibration control signal based on the combined wave generated in step 88 (step 89), and proceeds to the next step. For example, the control unit 31 generates the combined wave generated in step 88 as a vibration control signal as it is, and stores it in the vibration control signal data Ds.

  Next, the control unit 31 outputs a vibration control signal (step 90), and proceeds to the next step. For example, the control unit 31 outputs the vibration control signal CS indicated by the vibration control signal data Ds to the vibration generation unit 37. Thus, the vibration generating unit 37 causes the actuator 373 to generate a vibration corresponding to the vibration control signal CS.

  Next, the control unit 31 determines whether to end the process (step 91). The conditions for ending the process include, for example, that the conditions for ending the process are satisfied, and that the user has performed an operation for ending the process. The control unit 31 returns to the above step 82 to repeat the process when the process is not ended, and ends the process according to the flowchart when the process is ended.

  As described above, in the process according to the above-described embodiment, vibration data can be generated in the transfer destination device (for example, the information processing device 3) using the code data transferred from the transfer source device. Here, in the device of the transfer destination, it is possible to change the vibration parameter (for example, vibration frequency, vibration amplitude) during vibration of the actuator according to the code data transferred every predetermined cycle, so that vibration is generated. The code data can be handled efficiently when changing the vibration parameter.

  In the above-described embodiment, an example is used in which the vibration signal is generated based on the code data in the device of the transfer destination by transferring the code data between the devices. However, the vibration signal is generated according to another aspect. May be For example, code data generated for each predetermined cycle is stored in advance in a device that generates vibration signals (in the above example, the information processing device 3), and a vibration signal based on the code data is required. When it becomes, the vibration signal may be generated by acquiring and decoding code data stored in the own machine. This makes it possible to reduce the amount of data to be stored in order to generate the vibration signal in the device that generates the vibration signal.

  Moreover, although the example in which one actuator 373 is provided in the information processing apparatus 3 is used in the above-described embodiment, a plurality of actuators which give vibration to the user may be provided. As an example, a pair of actuators may be provided on the left and right of the information processing device 3. In this case, the control unit 31 may generate vibration control signals for driving the respective actuators from one piece of code data, or different pieces of code data (for example, code data for one actuator and the other Vibration control signals for driving the respective actuators may be respectively generated from code data for the actuators of

  For example, when a plurality of actuators 373 are provided and each actuator 373 generates independent vibration, a vibration control signal for controlling the vibration is output from the control unit 31 for each actuator 373. In this case, the codec unit 371 decodes the vibration control signal output from the control unit 31 to generate an analog vibration signal for generating vibration for each of the actuators 373 and outputs the analog vibration signal to the amplification unit 372. Then, the amplification unit 372 increases the amplitude change of the current / voltage of the analog vibration signal output from the codec unit 371, generates a drive signal, and outputs the drive signal to each of the plurality of actuators 373. When a plurality of actuators are provided in the information processing apparatus 3, the simulation 1 is performed by applying stimuli to two different points on the user's skin (as an example, the user's left and right hands gripping the information processing apparatus 3 main body) The actuator causes the user of the information processing apparatus 3 to cause the user to artificially perceive the position of the predetermined image displayed on the display unit 35 as if it is a vibration source using phantom sensation that causes point stimulation to be perceived. It also becomes possible to give.

  In the embodiment described above, an example in which the code data is wirelessly transmitted from the device at the transfer source to which the code data is transferred to the information processing device 3 has been used, but the code at the transfer source device to the information processing device 3 Data may be transmitted by wire. Even when the transfer rate for wireless or wired communication is slow, it is possible to prevent the delay of vibration control by sending code data.

  Further, the device to which code data is transferred may be an operating device (so-called controller) which the user holds and operates. In this case, an actuator for generating vibration is provided in the operation device, and code data for generating vibration data from the transfer source device of the code data (for example, the game apparatus body) to the operation device (for example, controller) is wireless It is transferred by communication. Then, the code data is decoded in the operation device, and drive control of the built-in actuator is performed based on the decoded vibration data. As described above, even in the game system including the game apparatus body and the controller wirelessly connected to the body, code data is transmitted from the game apparatus body to the controller to drive and control the actuator in the controller. Thus, the same effect as described above can be obtained. The controller wirelessly connected to the game apparatus main body may be a plurality (for example, a plurality of controllers held by a plurality of users or a pair of controllers held by one user in both hands), the game It may be a game system configured of a plurality of controllers each incorporating an apparatus body and an actuator. In this case, the code data for generating vibration data from the game apparatus body to the plurality of controllers are respectively transferred by wireless communication, so that each controller can generate vibration according to the code data. It should be noted that the process of encoding vibration data is not performed in the game apparatus body, and a program installed in the game apparatus body may include data in which the vibration data is encoded in advance. In this case, the game apparatus body outputs code data encoded in advance to the controller as needed, and the controller decodes the code data. The communication between the game apparatus body and the single or plural controllers may be wireless or wired.
