Title: Information processing device and information processing terminal

Description:
FIELD 
     The present disclosure relates to an information processing device and an information processing terminal. 
     BACKGROUND 
     In recent years, consumers&#39; consumption activities have shifted from “material consumption”, which is mere purchase of goods, to “experiential consumption” in which consumers pay for value-added experiences. For example, in the field of entertainment such as music and animations, consumers are demanding higher value-added experiences that are real-time and interactive, such as interactions between artists and fans, in addition to unidirectional experiences such as watching live performances by artists and so on. 
     Examples of this kind of experience include transmission of data such as illustrations and text to an artist or the like who distributes content on the Internet from viewers of the content, and “social tipping” of sending money along with the data transmission. The artist and the viewers communicate with each other via such “social tipping”, which provides higher value-added experiences to the viewers. This increases the viewers&#39; satisfaction with the content and increases their appetite for purchasing such “experiences”.

     1. Outline of Embodiment of Present Disclosure 
     First, before the embodiments of the present disclosure are detailed, the outline of the embodiments of the present disclosure created by the present inventors are described with reference to  FIGS.  1  and  2   .  FIGS.  1  and  2    are explanatory diagrams for explaining the outline of the embodiments of the present disclosure. 
     As described earlier, consumers&#39; consumption activities have recently shifted from “material consumption” to “experiential consumption”. In particular, in the field of entertainment, consumers are demanding higher value-added experiences that are real-time and interactive, such as interactions with artists, in addition to unidirectional experiences such as watching live performances by artists and so on. 
     Therefore, in light of such a situation, the inventors have been diligently studying the possibility of providing viewers with higher value-added experiences, and came up with the idea of using a tactile presentation device (haptic device) that presents tactile stimuli such as vibrations to a person who wears the device. According to the inventors&#39; consideration, the use of such a tactile presentation device enables the viewers to obtain higher value-added experiences. 
     In embodiments of the present disclosure created on the basis of such an idea, as illustrated in  FIG.  1   , an artist  602  whose performance or content is to be watched or distributed wears, for example, a vest-type tactile presentation device  100 . The tactile presentation device  100  includes a plurality of tactile stimulus units (for example, actuators or the like) therein. Furthermore, in response to a predetermined signal received, the tactile stimulus units can present tactile stimuli to the wearer. Then, as illustrated in  FIG.  2   , a viewer  600  selects one stamp  700  with tactile stimulus effect from the stamps  700  with tactile stimulus effect displayed on a display unit  302  of the user terminal  300  to send the selected stamp  700  with tactile stimulus effect; thereby, a predetermined tactile control signal corresponding to the tactile stimulus given to the stamp  700  is sent to the tactile stimulus unit (so-called “social tipping” with the tactile stimulus effect is made). Furthermore, the tactile stimulus unit presents, to the wearer, the tactile stimulus corresponding to the selected stamp  700  with tactile stimulus effect on the basis of the predetermined tactile control signal received. Therefore, if the artist  602  perceives the presented tactile stimulus and takes action, the viewer  600  can confirm, in real time, the action induced by the tactile stimulus presented by the stamp  700  that the viewer  600  has sent. Then, if the viewer  600  can confirm, in real time, the action induced by the tactile stimulus related to the stamp  700  that he/she has sent, then the viewer  600  can feel as if he/she directly interacts with the artist  602 , that is, the viewer  600  can obtain a higher value-added experience. 
     As described above, in the embodiments of the present disclosure created by the inventors, the viewer  600  can send, to the artist  602 , not only visual information such as illustrations, animations, and text and auditory information such as music, but also tactile information. Therefore, according to the embodiments of the present disclosure, it is possible to provide the viewer  600  with a real-time, interactive, and value-added experience, which increases his/her satisfaction with the performance and the content, and increases his/her appetite for purchasing such “experiences”. The details of the embodiments of the present disclosure created by the inventors are sequentially described below. 
     2. First Embodiment 
     2.1 Outline of Information Processing System  10   
     First, the outline of the information processing system  10  according to the first embodiment of the present disclosure is described with reference to  FIG.  3   .  FIG.  3    is a system diagram illustrating an example of a schematic configuration of an information processing system  10  according to the first embodiment of the present disclosure. In the following description, it is assumed that an artist (second user)  602  and a viewer (first user)  600  are present in different spaces or the same space. Specifically, in the information processing system  10 , the viewer  600  may, for example, directly views the artist  602 , or may view video of the artist  602  distributed. 
     Specifically, as illustrated in  FIG.  3   , the information processing system  10  according to the embodiment can include, for example, a tactile presentation device  100 , a monitor  110 , a camera  120 , a server (information processing device)  200 , and a smartphone  300   a  and a tablet terminal  300   b  as an example of the user terminal (information processing terminal)  300 . The server  200  and other devices can send and receive data via various communication networks, such as a wired/wireless local area network (LAN), Wi-Fi (registered trademark), Bluetooth (registered trademark), a mobile communication network (long term evolution (LTE), and 5G (5th generation mobile communication system). Note that the number of devices included in the information processing system  10  is not limited to the number illustrated in  FIG.  3   , and may be further greater. Furthermore, the information processing system  10  may include a device that is not illustrated in  FIG.  3   . For example, the information processing system  10  may include a general-purpose personal computer (PC), a game machine, a cell phone, a portable media player, a speaker, a projector, a display (digital signage, etc.), a wearable device such as headphones, smart glasses, or a smart watch. The outline of the individual devices included in the information processing system  10  according to the embodiment is described below. 
     (Tactile Presentation Device  100 ) 
     The tactile presentation device  100  is implemented by, for example, a device that can be worn on the body. In the embodiment, the tactile presentation device  100  is assumed to be of a vest-type (sleeveless outwear shape) worn by the artist  602 , for example. As described early, the vest-type tactile presentation device  100  includes a plurality of tactile stimulus units therein. For example, a predetermined number (for example, six) of tactile stimulus units may be arranged, inside the tactile presentation device  100 , on each of the front side and the back side of the artist  602 . As an example, the individual tactile stimulus units arranged on the front side and the individual tactile stimulus units arranged on the back side are arranged in a facing positional relationship. 
     In the embodiment, the shape of the tactile presentation device  100  is not limited to the vest-type, and may have an outwear shape with sleeves. In such a case, one or more tactile stimulus units may be placed not only on the chest and abdomen of the artist  602  but also at positions corresponding to both arms of the artist  602 . Furthermore, in the embodiment, the tactile presentation device  100  is not limited to the outerwear shape, and may be trousers, shoes, a belt, a hat, gloves, a mask, or the like. 
     Furthermore, one microphone (hereinafter, referred to as a “microphone”) (not illustrated) may be placed on each side of the shoulder part of the tactile presentation device  100 , or one microphone may be placed on one of the left and right sides thereof, or three or more microphones may be placed. Furthermore, the microphone may be placed around the artist  602  as another device independent of the tactile presentation device  100 . Furthermore, the tactile presentation device  100  may include a worn state detection sensor (for example, a zipper-type sensor, a pressure sensor, etc.) (not illustrated) for detecting the worn state of the tactile presentation device  100 , an inertial sensor (inertial measurement unit (IMU)) (not illustrated) for detecting action and posture of the artist  602 , a biometric information sensor for detecting biometric information of the artist  602  (for example, sensor for sensing heartbeat, pulse, brain waves, respiration, sweating, myoelectric potential, skin temperature, skin electrical resistance, eye movement, or pupil diameter, etc.) (not illustrated). The detailed configuration of the tactile presentation device  100  is described later. 
     (Monitor  110 ) 
     The monitor  110  can display, for the artist  602 , an image of the artist  602  captured by the camera  120  described later for example, and the monitor  110  further can superimpose text, an icon, an animation, or the like on the image of the artist  602 . The monitor  110  is implemented by, for example, a liquid crystal display (LCD) device and an organic light emitting diode (OLED) device. Furthermore, in the embodiment, a display unit (not illustrated) of the monitor  110  may be provided as a unit integrated with an input unit (not illustrated), and in such a case, the input unit is implemented by a touch panel superimposed on the display unit. Furthermore, in the embodiment, the monitor  110  may be provided with a speaker (not illustrated) for outputting a sound to the artist  602 . 
     (Camera  120 ) 
     The camera  120  is one or more visible light cameras that capture images of the artist  602  from one or multiple viewpoints, and an image captured is sent to the user terminal  300  or the monitor  110  of the viewer  600  via the server  200 . The camera  120  may capture an image of the surroundings of the artist  602  or a real object that is present around the artist  602 . Specifically, the camera  120  includes a lens system having an image pickup lens, a diaphragm, a zoom lens, and a focus lens, and a drive system that causes the lens system to perform a focus operation and a zoom operation. The camera  120  also includes a solid-state imaging element array that photoelectrically converts imaging light captured by the lens system to generate an imaging signal. The solid-state imaging element array may be implemented by, for example, a charge coupled device (CCD) sensor array or a complementary metal oxide semiconductor (CMOS) sensor array. 
     (Server  200 ) 
     The server  200  can receive a stamp (control command)  700  with tactile stimulus effect inputted by the viewer  600 , generate a tactile control signal in accordance with the stamp  700 , and send the generated tactile control signal to the tactile presentation device  100 . Each stamp  700  with tactile stimulus effect is correlated with each predetermined control command, and each control command includes information for designating a perceptual location where a vibration stimulus is to be presented (positional information), and information for designating a waveform type and intensity of the vibration stimulus for example (mode information). Specifically, the server  200  generates a tactile control signal (waveform data) to be inputted to the individual tactile stimulus units of the tactile presentation device  100  so as to present a vibration stimulus with the intensity and waveform designated in the control command at the perceptual location designated therein, and sends the tactile control signal to the tactile presentation device  100 . Note that, in the specification, the “perceptual location” includes a movement path of the perceptual location and a perceptual range having a predetermined size. 
     Furthermore, in the embodiment, the server  200  may be implemented by a single device as illustrated in  FIG.  3    or a plurality of devices, and the present disclosure is not particularly limited to this example. For example, the server  200  may be implemented by a server (not illustrated) dedicated for the tactile presentation device  100  and a distribution server (not illustrated) for distributing content. In such a case, the server dedicated for the tactile presentation device  100  authenticates via a web application programming interface (web API), monitors the stamp  700  with tactile stimulus effect sent by the viewer  600  and the like, and controls the tactile presentation device  100 . On the other hand, the distribution server distributes, to the user terminal  300 , an image of the artist  602  or the like, an image for selecting the stamp  700  with tactile stimulus effect, or the like. Furthermore, the server  200  may include, for example, a settlement server (not illustrated) that performs payment for the use of the information processing system  10 . Detailed configuration of the server  200  is described later. 
     (User Terminal  300 ) 
     The user terminal  300  is a terminal that is used by the viewer  600  or installed in the vicinity of the viewer  600 , and is used for the viewer  600  to input the stamp  700  with tactile stimulus effect or the like. The user terminal  300  receives the stamp (control command)  700  with tactile stimulus effect inputted by the viewer  600 , and sends the received stamp  700  to the server  200 . For example, the user terminal  300  can be the smartphone  300   a , the tablet personal computer (PC)  300   b , a cell phone, a laptop PC, or a wearable device such as a head mounted display (HMD). Detailed configuration of the user terminal  300  is described later. 
     2.2 Detailed Configuration of Tactile Presentation Device  100   
     Next, the detailed configuration of the tactile presentation device  100  is described with reference to  FIGS.  4  and  5   .

As described above, the tactile presentation device  100  is a device that is attached to a part of the body of the artist  602  and vibrates in accordance with a control command to give a tactile stimulus to the artist  602 . 
     As illustrated in  FIG.  4   , for example, the vest-type tactile presentation device  100  includes a plurality of tactile stimulus units  106  therein as described early. The tactile stimulus unit  106  includes, for example, an actuator, is driven by a tactile control signal generated by the server  200  to generate vibrations, and presents such vibrations as a tactile stimulus. Examples of the actuator include an eccentric motor, a linear vibrator, a piezoelectric element, and the like. 
     As illustrated in  FIG.  5   , the tactile presentation device  100  includes a communication unit  102 , a control unit  104 , and the tactile stimulus unit  106 . The communication unit  102  is connected to the server  200  by wire or wirelessly, and sends/receives information to/from the server  200 . The control unit  104  is a controller, and drives the tactile stimulus unit  106  on the basis of a tactile control signal inputted via the communication unit  102 . The control unit  104  is implemented, for example, in response to various programs, stored in read only memory (ROM) or the like of the tactile presentation device  100 , executed by a central processing unit (CPU), a micro processing unit (MPU), or the like using random access memory (RAM) as a work area. Alternatively, the control unit  104  can be implemented, for example, by an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). 
     Although the detailed configuration of the tactile presentation device  100  according to the embodiment has been specifically described above, the detailed configuration of the tactile presentation device  100  according to the embodiment is not limited to the examples illustrated in  FIGS.  4  and  5   . 
     Furthermore, the tactile presentation device  100  is not limited to the wearable type device as described above, and may also be configured as an on-hand type device that is mounted on a device held by the artist  602 , for example, a smartphone, a game controller, a portable music player, or the like. Alternatively, the tactile presentation device  100  is not limited to the wearable type device and the on-hand type device, and may also be configured as a slate/floor type device that is mounted on furniture such as a bed or a chair or various facilities. 
     2.3 Detailed Configuration of Server  200   
     Next, the detailed configuration of the server  200  according to the embodiment of the present disclosure is described with reference to  FIG.  6   .  FIG.  6    is a diagram illustrating an example of the functional configuration of the server  200  according to the embodiment. As illustrated in  FIG.  6   , the server  200  mainly includes a communication unit  202 , a control unit  210 , and a storage unit  240 . Hereinafter, the functional blocks of the server  200  are described sequentially. 
     (Communication Unit  202 ) 
     The communication unit  202  can send and receive information to and from the tactile presentation device  100 , the monitor  110 , the camera  120 , and the user terminal (information processing terminal)  300 . The communication unit  202  is a communication interface having a function to send and receive data, and is implemented by a communication device (not illustrated) such as a communication antenna, a transmission/reception circuit, and a port. 
     (Control Unit  210 ) 
     The control unit  210  is a controller, and is implemented, for example, in response to various programs, stored in ROM or the like of the server  200 , executed by a CPU, an MPU, or the like using RAM as a work area. Specifically, as illustrated in  FIG.  6   , the control unit  210  may include a GUI control unit  212 , a viewer side input unit (first acquisition unit)  214 , a distributor side input unit  216 , a generation unit  218 , a determination unit  220 , and an output control unit (first distribution unit)  222 . 
     The graphical user interface (GUI) control unit  212  controls the user terminal  300  of the viewer  600  to display a screen to which the stamp (control command)  700  with tactile stimulus effect is inputted. Specifically, the GUI control unit  212  causes the display unit  302  of the user terminal  300  to display the screen as illustrated in  FIG.  2    as a screen on which to select the stamp  700  with tactile stimulus effect. A large number of stamps  700  with tactile stimulus effect are displayed on the selection screen (stamp selection screen). Each stamp  700  with tactile stimulus effect is correlated with a control command for the tactile presentation device  100 , and the viewer  600  can select the stamp  700  displayed on the selection screen to input a control command. In the embodiment, it is preferable that an image of the stamp  700  with tactile stimulus effect intuitively evokes the tactile stimuli, thoughts (message), and so on that the viewer  600  wishes to send to the artist  602 . 
     The viewer side input unit  214  acquires a control command including positional information for designating a presentation position at which to present the tactile stimulus by the tactile presentation device  100  and mode information for designating a mode of the tactile stimulus, the control command being correlated with the stamp  700  with tactile stimulus effect inputted by the viewer  600 , and outputs the control command to the generation unit  218  described later. 
     The distributor side input unit  216  acquires, for example, sensing data or the like acquired by a worn state detection sensor (not illustrated) for detecting a worn state of the tactile presentation device  100 , and outputs the sensing data or the like to the generation unit  218  described later. 
     The generation unit  218  generates a tactile control signal for controlling the tactile presentation device  100  on the basis of the control command correlated with the stamp  700  with tactile stimulus effect inputted by the viewer  600 , and outputs the tactile control signal to the determination unit  220  described later. Specifically, the generation unit  218  generates, on the basis of the control command including a perceptual location of a vibration stimulus (positional information), a waveform type of the vibration stimulus, and intensity information on the vibration stimulus (mode information), waveform data to be inputted to the individual tactile stimulus units of the tactile presentation device  100  so as to present a vibration stimulus with the intensity and waveform designated in the control command at the perceptual location designated therein. Note that the tactile control signal may include information for giving a command to present the vibration stimulus at a presentation timing, frequency, interval, and presentation time of a tactile stimulus based on the control command. If the frequency and intensity of the vibration stimulus designated in the control command has a wide band (e.g., 50 to 500 Hz), then the generation unit  218  may compress it to a narrow band (e.g., 100 Hz) according to the function of the tactile presentation device  100 , and generate waveform data. 
     The generation unit  218  may also adjust the tactile control signal according to the worn state of the tactile presentation device  100  of the artist  602 . For example, the generation unit  218  adjusts the tactile control signal according to a contact rate between the tactile presentation device  100  and the body of the artist  602 . More specifically, the generation unit  218  adjusts the tactile control signal so that the tactile vibration is not presented for the tactile stimulus unit  106  at a location where the contact rate is low. The generation unit  218  may also adjust the tactile control signal according to attribute information (age, gender, height, weight, physique, and so on, for example) and biometric information of the artist  602 . For example, the generation unit  218  may adjust the perceptual location, intensity, and the like according to the age of the artist  602 . More specifically, in a case where the artist  602  is six years old, the generation unit  218  may adjust the tactile control signal so that the intensity of the tactile stimulus to be presented is a half of the intensity for a case where the artist  602  is an adult. 
     Furthermore, the generation unit  218  may generate, together with the tactile control signal, a presentation control signal (for example, a control signal when not worn or the like) for presenting a predetermined image or a predetermined sound to the viewer  600  or the artist  602 . For example, the predetermined image can be a virtual object such as an icon, an animation, or text that is superimposed on an image of the artist  602  or an image of the real space around the artist  602 , or is projected onto the artist  602 ; and more specifically, the predetermined image can be a trajectory of a social tip moving from the viewer  600  to the artist  602 , an animation that looks like a bomb exploding, which is displayed at the same time as the tactile stimulus is presented, or an icon corresponding to the stamp  700  with tactile stimulus effect inputted by the viewer  600 . Furthermore, the predetermined image or the predetermined sound can be, for example, an image or sound that is outputted to the viewer  600  instead of a tactile stimulus in a case where the tactile stimulus cannot be presented to the artist  602  because the tactile presentation device  100  is not worn on the body of the artist  602 . 
     The determination unit  220  determines whether or not to send a tactile control signal to the tactile presentation device  100  on the basis of the content of the control command and the tactile control signal, the attribute information of the viewer  600  or the artist  602 , and so on. For example, in a case where the control command inputted by the viewer  600  designates the presentation position and intensity restricted by the artist  602  in advance, the determination unit  220  determines that a tactile control signal generated on the basis of the control command is not sent to the tactile presentation device  100 . Furthermore, in a case where different viewers  600  designate the same presentation position consecutively, or in a case where the same viewer  600  inputs control commands continuously, the determination unit  220  may determine that the tactile control signal generated is not sent to the tactile presentation device  100 . Furthermore, in such a case, the generation unit  218  may change the presentation position of the tactile stimulus. 
     The output control unit  222  sends the generated tactile control signal to the tactile presentation device  100  worn on the body of the artist  602  via the communication unit  202 . 
     (Storage Unit  240 ) 
     The storage unit  240  is implemented by a storage device such as ROM that stores programs and operation parameters used for processing of the control unit  210 , RAM that temporarily stores parameters changing as appropriate, and a hard disk drive (HDD) that stores various databases (DBs). As illustrated in  FIG.  6   , for example, the storage unit  240  can include a viewer profile  242 , a distributor profile  244 , and a distribution data DB  246 . The viewer profile  242  and the distributor profile  244  store attribute information of the viewer  600  and the artist  602 , respectively. Furthermore, the viewer profile  242  may store, in correlation with the identification information of the viewer  600 , information on control commands that the viewer  600  has acquired or used in the past, and the distributor profile  244  may store, in correlation with the identification information of the artist  602 , information on control commands that the artist  602  has received in the past. Furthermore, the distribution data DB  246  stores a tactile data library (vibration waveform pattern, and so on) generated in advance in correlation with the identification information of each stamp  700 , and the generation unit  218  uses the tactile data library to generate a tactile control signal. Furthermore, the distribution data DB  246  may store, as the profile information of the tactile presentation device  100 , for example, information such as the number of tactile stimulus units  106  of the tactile presentation device  100 , the locations thereof, frequency characteristics, and maximum input voltage. The generation unit  218  can adjust the tactile control signal with reference to the profile information. 
     Although the detailed configuration of the server  200  according to the embodiment has been specifically described above, the detailed configuration of the server  200  according to the embodiment is not limited to the example illustrated in  FIG.  6   . For example, the server  200  may further include a recommendation unit (not illustrated) that refers to the viewer profile  242  and the distributor profile  244  to select a control command that the viewer  600  or the artist  602  uses frequently, or conversely, a control command that the viewer  600  or the artist  602  uses less frequently, and recommends, to the viewer  600 , a stamp  700  with tactile stimulus effect that is correlated with the selected control command. Furthermore, the recommendation unit may recommend, to the viewer  600 , a stamp  700  with tactile stimulus effect recommended by the artist  602 . 
     2.3 Detailed Configuration of User Terminal  300   
     Next, the detailed configuration of the user terminal  300  according to the embodiment of the present disclosure is described with reference to  FIG.  7   .  FIG.  7    is a diagram illustrating an example of the functional configuration of the user terminal  300  according to the embodiment. As illustrated in  FIG.  7   , the user terminal  300  mainly includes the display unit  302 , an operation input unit  304 , a speaker  306 , a communication unit (transmission unit) (price acquisition unit)  308 , a control unit  310 , a storage unit  312 , and a sensor unit  320 . Hereinafter, the functional blocks of the user terminal  300  are described sequentially. 
     (Display Unit  302 ) 
     The display unit  302  can display, for the viewer  600 , a selection screen for selecting a stamp (control command)  700  with tactile stimulus effect, an image of the artist  602 , and so on for example. The display unit  302  can also superimpose text, an icon, an animation, or the like on the image of the artist  602 . The display unit  302  is implemented by a liquid crystal display device, an OLED device, or the like. 
     (Operation Input Unit  304 ) 
     The operation input unit  304  receives, from the viewer  600 , a selection result of the stamp  700  with tactile stimulus effect that is correlated with a control command including positional information for designating a presentation position at which to present a tactile stimulus and mode information for designating a mode of the tactile stimulus. Alternatively, the operation input unit  304  may directly receive an input of the control command. For example, the operation input unit  304  is implemented by a switch, a button, a touch panel, a lever, or the like. Furthermore, the content of the operation inputted by the operation input unit  304  may be displayed on the display unit  302 . Furthermore, the operation input unit  304  can receive information on input operation (e.g., positional information) that the viewer  600  enters on a position selection screen that is provided so as to be superimposed on the display unit  302  and is to designate a presentation position displayed on the display unit  302 . 
     (Speaker  306 ) 
     The speaker  306  reproduces an audio signal or the like under the control of the control unit  310  described later. Note that the speaker  306  may be provided in the user terminal  300 , or may be a device separated from the user terminal  300 , such as a pair of earphone speakers (not illustrated). 
     (Communication Unit  308 ) 
     The communication unit  308  can send and receive information to and from the server  200 , and specifically, can send, to the server  200 , information on a stamp (control command)  700  with tactile stimulus effect inputted by the viewer  600 . Furthermore, the communication unit  308  can receive information (for example, information such as a price of the stamp (control command)  700  with tactile stimulus effect) sent from the server  200 . For example, the communication unit  308  is a communication interface having a function to send and receive data, and is implemented by a communication device (not illustrated) such as a communication antenna, a transmission and reception circuit, and a port. 
     (Control Unit  310 ) 
     The control unit  310  is a controller of the user terminal  300 , and is implemented, for example, in response to various programs, stored in ROM or the like of the user terminal  300 , executed by a CPU, an MPU, or the like using RAM as a work area. 
     (Storage Unit  312 ) 
     The storage unit  312  is implemented by a storage device such as ROM that stores programs, operation parameters, and the like used for the processing of the control unit  310 , and RAM that temporarily stores parameters and the like changing as appropriate. 
     (Sensor Unit  320 ) 
     The sensor unit  320  can acquire sensing data on operation (vibrations or the like given to the user terminal) from the viewer  600 . For example, as illustrated in  FIG.  7   , the sensor unit  320  mainly includes a camera  322 , a microphone  324 , a gyro sensor  326 , and an acceleration sensor  328 . Note that the sensors are examples, and the embodiment is not limited thereto. 
     For example, the camera  322  captures an image of motion or the like of the viewer  600  to output the captured image to the control unit  310 . The control unit  310  can then extract predetermined motion of the viewer  600  from the image captured by the camera  322  and acquire a control command related to the extracted motion. Specifically, the camera  322  includes a lens system having an image pickup lens, a diaphragm, a zoom lens, and a focus lens, and a drive system that causes the lens system to perform a focus operation and a zoom operation. The camera  322  also includes a solid-state imaging element array that photoelectrically converts imaging light captured by the lens system to generate an imaging signal. Note that the solid-state imaging element array may be implemented by, for example, a CCD sensor array or a CMOS sensor array. Furthermore, the camera  322  may include a time of flight (ToF) sensor (not illustrated). The ToF sensor, for example, irradiates an object with irradiation light having a predetermined cycle, detects reflected light reflected from the object, and detects a phase difference and a time difference between the irradiation light and the reflected light, thereby acquiring depth information of the object. Here, the depth information of the object is depth information which is one piece of the information of the distance from the ToF sensor to each point on the surface of the object. Then, by aggregating the depth information on the plurality of points on the surface of the object, shape information on the unevenness of the surface of the object, i.e., the outer shape information on the object can be obtained. 
     The microphone  324  collects a sound of the viewer  600  to output the collected sound information to the control unit  310 . The control unit  310  can then extract a predetermined sound pattern of the viewer  600  from the sound collected by the microphone  324  and acquire a control command related to the extracted sound pattern. 
     The gyro sensor  326  is implemented by, for example, a three-axis gyro sensor, and detects an angular velocity (rotation speed) of the movement of the user terminal  300  by the viewer  600 . Furthermore, the acceleration sensor  328  is implemented by, for example, a three-axis acceleration sensor (also called a G sensor), and detects the acceleration of the movement of the user terminal  300  by the viewer  600 . In the embodiment, the sensing data from these sensors can be used to recognize the operation performed by the viewer  600  on the user terminal  300 , leading to the acquisition of a control command related to the recognized operation. 
     Although the detailed configuration of the user terminal  300  according to the embodiment has been specifically described above, the detailed configuration of the user terminal  300  according to the embodiment is not limited to the example illustrated in  FIG.  7   , and may further include, for example, a vibration device (not illustrated) for making a notification to the viewer  600  through vibration. 
     2.4 Information Processing Method 
     The devices of the information processing system  10  according to the embodiment has been detailed above. Next, an example of the information processing method according to the embodiment is described with reference to  FIGS.  8  to  12   .  FIG.  8    is a flowchart depicting an example of the information processing method according to the embodiment.  FIGS.  9  to  12    are explanatory diagrams for explaining a display example according to the embodiment. As illustrated in  FIG.  8   , an example of the information processing method according to the embodiment includes a plurality of steps from Step S 101  to Step S 106 . The details of the steps included in the example of the information processing method according to the embodiment are described below. 
     First, the viewer  600  selects one stamp  700  with tactile stimulus effect from the stamps  700  with tactile stimulus effect displayed on the display unit  302  of the user terminal  300 , and sends the selected stamp  700  to the server  200 . In the embodiment, before sending, the viewer  600  may tap the displayed stamp  700  to reproduce a tactile stimulus corresponding to the control command correlated with the stamp  700  for example, and in such a case, the user terminal  300  vibrates so as to correspond to the tactile stimulus, for example. 
     The server  200  then acquires information on the stamp  700  with tactile stimulus effect that is sent from the user terminal  300 , selected by the viewer  600 , and is correlated with the control command (Step S 101 ). 
     Next, the server  200  acquires, with reference to the distribution data DB  246  and the like, positional information for designating a presentation position at which to present the tactile stimulus included in the control command correlated with the acquired stamp  700  (Step S 102 ). 
     Furthermore, the server  200  acquires, with reference to the distribution data DB  246  and the like, mode information for designating a mode of the tactile stimulus included in the control command correlated with the acquired stamp  700  (Step S 103 ). 
     The server  200  then generates waveform data as a tactile control signal for controlling the tactile presentation device  100  on the basis of the positional information and the mode information acquired in Step S 102  and Step  3103  (Step S 104 ). 
     Next, the server  200  determines whether or not to send the generated tactile control signal to the tactile presentation device  100 , for example, on the basis of the attribute information of the artist  602  (NG determination) (Step S 105 ). 
     In a case where it is determined, in Step S 105 , that the tactile control signal is to be sent to the tactile presentation device  100 , the server  200  sends the generated tactile control signal to the tactile presentation device  100  worn on the body of the artist  602  (Step S 106 ), and the processing ends. On the other hand, in a case where it is determined, in Step S 105 , that the tactile control signal is not to be sent to the tactile presentation device  100 , the server  200  may notify the viewer  600  via the user terminal  300  that the tactile control signal is not to be sent. 
     The artist  602  then perceives the tactile stimulus presented via the tactile presentation device  100  and takes action. The viewer  600  can check, in real time, the action of the artist  602  induced by the tactile stimulus presented by the stamp  700  that the viewer  600  has sent. If the viewer  600  can confirm, in real time, the action induced by the tactile stimulus related to the stamp  700  that he/she has sent, then the viewer  600  can feel as if he/she is in direct contact with the artist  602 , and can feel a sense of unity with the artist  602 . 
     Note that, in the embodiment, not only the tactile stimulus is presented by the tactile presentation device  100  worn on the body of the artist  602 , but also, for example, as illustrated in  FIG.  9   , a display  800  or the like may be superimposed on the image of the artist  602  or the like on the display unit  302  of the user terminal  300 . At this time, the display  800  is preferably superimposed at a position where the tactile stimulus is presented. Furthermore, in the embodiment, the display  800  may have a design corresponding to the design of the stamp  700  with tactile stimulus effect selected by the viewer  600 . For example, if the stamp  700  is designed to arrow through heart, then the display  800  can also be designed to arrow through heart. Furthermore, in the embodiment, at the time of presentation of a tactile stimulus, an image displayed on the display unit  302  of the user terminal  300  may move up, down, left, and right in accordance with the tactile stimulus. Furthermore, in the embodiment, at the time of presentation of a tactile stimulus by the tactile presentation device  100  worn on the body of the artist  602 , the user terminal  300  of the viewer  600  who has sent the corresponding tactile stimulus may be vibrated, or the user terminals  300  of the artist  602  or other viewers  600  who are present around that viewer  600  may also be vibrated. 
     Furthermore, in the embodiment, in a case where the generated tactile control signal is sent to the tactile presentation device  100 , as illustrated in  FIG.  10   , an icon (predetermined icon)  806  such as a coin and a trajectory  808  of the icon  806  moving from the viewer  600  side to the artist  602  may be displayed on the display unit  302  of the user terminal  300 , a display unit (not illustrated) of the monitor  110 , or the like. Display of such a trajectory  808  allows the viewer  600  to realize that the stamp  700  sent by himself/herself is being sent to the artist  602 . 
     Furthermore, in the embodiment, as illustrated in  FIG.  11   , the artist  602  who has perceived the tactile stimulus may display a comment  810  inputted via a distributor terminal (not illustrated) on the display unit  302  of the user terminal  300  or the like, for example. 
     Furthermore, in the embodiment, in a case where the artist  602  does not wear the tactile presentation device  100 , the server  200  may stop sending a tactile control signal, and in such a case, the server  200  may send the tactile control signal in a case where the attachment of the tactile presentation device  100  to the artist  602  wears is newly detected. Furthermore, in a case where the transmission of the tactile control signal is stopped, as illustrated in  FIG.  12   , a notification  804  indicating the stop may be displayed on, for example, the display unit  302  of the user terminal  300  or the like, or the user terminal  300  may be vibrated for the notification. 
     Furthermore, in the embodiment, in a case where the artist  602  does not wear the tactile presentation device  100 , as illustrated in  FIG.  12   , an animation showing that a tactile stimulus is presented to avatar  802  as a substitute for the artist  602  may be displayed on the display unit  302  of the user terminal  300  or the like by an in-wearing control signal. At this time, the display  800  is preferably superimposed at a position on the avatar  802  corresponding to the position where the tactile stimulus is presented. 
     As described above, according to the embodiment, the tactile stimulus corresponding to the stamp  700  with tactile stimulus effect selected by the viewer  600  can be presented to the artist  602 . Therefore, in the embodiment, if the artist  602  perceives the presented tactile stimulus and takes action, then the viewer  600  can confirm, in real time, the action induced by the tactile stimulus presented by the stamp  700  that the viewer  600  has sent. Then, according to the embodiment, if the viewer  600  can confirm, in real time, the action induced by the tactile stimulus related to the stamp  700  that he/she has sent, then the viewer can feel as if he/she directly interacts with the artist  602 , that is, the viewer  600  can obtain a real-time, interactive, and value-added experience. 
     2.5 Modification Example 
     Furthermore, in the embodiment, in a case where the tactile presentation device  100  is worn on the body of the viewer  600 , “throwback” by the artist  602 , in other words, a tactile stimulus corresponding to a stamp  700  with tactile stimulus effect selected by the artist  602  may be presented to the viewer  600 . According to the modification example, in a case where the tactile stimulus presented by the stamp  700  sent by the viewer  600  serves as a start point and the artist  602  returns the tactile stimulus to the viewer  600 , the viewer  600  can feel as if he/she directly communicates with the artist  602 . 
     In the modification example, for example, as with the first embodiment, when the artist  602  selects and sends the stamp  700  with tactile stimulus effect, the tactile presentation device  100  of the viewer  600  presents the tactile stimulus also to the viewer  600 . Specifically, in the modification example, the server  200  acquires the stamp  700  with tactile stimulus effect inputted by the artist  602 , generates a tactile control signal according to a control command correlated with the acquired stamp  700 , and sends the generated tactile control signal to the tactile presentation device  100  worn on the body of the viewer  600 . 
     Furthermore, in the modification example, in a case where the tactile presentation device  100  is not worn on the body of the viewer  600  at the time of “throwback” by the artist  602 , the user terminal  300  may be used instead of the tactile presentation device  100 . 
     In the modification example, for example, the server  200  controls the user terminal  300  to output a sound, vibrate, blink, or the like in response to the control command correlated with the stamp  700  with tactile stimulus effect inputted by the artist  602 . Specifically, in the modification example, in such a case, the server  200  acquires the stamp  700  with tactile stimulus effect inputted by the artist  602 , generates a control signal for user terminal on the basis of the control command correlated with the acquired stamp  700  and the functional information (attribute information) of the user terminal  300 , and sends the generated control signal for user terminal to the user terminal  300 . 
     3. Second Embodiment 
     In the first embodiment, the viewer  600  inputs a control command by selecting a stamp  700  correlated with a control command determined in advance; however, the embodiment of the present disclosure is not limited to such a form, and for example, the viewer  600  can freely edit a tactile stimulus (control command) itself. In this way, if the viewer  600  can freely edit the tactile stimulus, for example, the viewer  600  can confirm, in real time, the action of the artist  602  induced by the tactile stimulus that the viewer  600  has edited, and can feel as if he/she is in direct contact with the artist  602 . In view of this, an embodiment according to such an editing method is described below as the second embodiment with reference to  FIGS.  13  and  14   .  FIGS.  13  and  14    are explanatory diagrams for explaining a display example according to the second embodiment of the present disclosure. 
     First, the viewer  600  can perform operation on a position selection screen displayed on the display unit  302  of the user terminal  300  as illustrated in  FIG.  13    to input positional information for designating a perceptual location at which to present a tactile stimulus. 
     Specifically, as illustrated in  FIG.  13   , a human body model display  812  is shown in the position selection screen, and a plurality of regions  814  is further shown, on the human body model display  812 , at positions corresponding to the tactile stimulus units  106  of the tactile presentation device  100 . The viewer  600  can move a marker  816  over a region  814  corresponding to the perceptual location to be selected to set and input the perceptual location. Note that, the embodiment is not limited to pinpointing the perceptual location and setting and inputting the same, and for example, a movement path of the perceptual location may be set and inputted by tracing the human body model display  812 , or a perceptual range having a predetermined size may be set and inputted. Then, the viewer side input unit  214  of the server  200  acquires the positional information inputted on the position selection screen. 
     In the embodiment, even if the installation location and the number of the tactile stimulus units  106  are limited, a tactile stimulus can be presented at a perceptual location desired by the viewer  600  according to the following principle. Specifically, an illusory phenomenon called phantom sensation is medically known. Phantom sensation is an illusory phenomenon in which, when stimuli are presented simultaneously at different locations on the skin, a human perceives only one stimulus between the presented stimulus locations. Therefore, in the embodiment, by using such phantom sensation, for example, when tactile stimuli are simultaneously presented to the two tactile stimulus units  106 , the location at which the tactile stimulus is perceived can be a location between the two tactile stimulus units  106 . Furthermore, in the embodiment, by changing the output intensity of the plurality of tactile stimulus units  106 , the range of the tactile stimulus that can be presented by the plurality of tactile stimulus units  106  can be expanded without changing the arrangement interval between the tactile stimulus units  106 . 
     In addition, the embodiment is not limited to the setting and inputting on the position selection screen as illustrated in  FIG.  13   . For example, in a case where a vest-type sensor (first sensor) similar to the tactile presentation device  100  is worn on the body of the viewer  600  and the sensor can detect a touch operation by the viewer  600 , the viewer  600  may perform an operation on the sensor to set and input a perceptual location. The viewer side input unit  214  of the server  200  acquires positional information inputted to the sensor. Furthermore, the sensor is not limited to being worn on the body of the viewer  600 , and may be worn on, for example, a doll (not illustrated). 
     Furthermore, in the embodiment, it is possible to edit and set also a waveform type, intensity, presentation timing, frequency, interval, presentation time, and the like of the vibration stimulus. For example, it is possible to edit the waveform type, intensity, presentation timing, frequency, interval, presentation time, and the like of the tactile stimulus by performing an operation on an edit screen (mode selection screen) displayed on the display unit  302  of the user terminal  300  as illustrated in  FIG.  14   . Specifically, as illustrated in  FIG.  14   , a waveform  826  is displayed on the time axis in the edit screen, and the viewer  600  can edit the waveform  826  by performing an operation on the waveform  826 . Furthermore, a cursor or the like is displayed in the edit screen, and the viewer  600  can set the intensity, frequency, and the like of the tactile stimulus by moving a cursor  824  ( FIG.  14    illustrates, for example, an edit screen where the velocity (speed) of throwing the stamp  700  with tactile stimulus effect and the frequency of the tactile stimulus can be set). The viewer side input unit  214  of the server  200  acquires mode information inputted into the mode selection screen. 
     In the embodiment, a range of values or the like that the viewer  600  can edit may be set in advance on the basis of the attribute information of the artist  602 . For example, for a male artist  602 , the intensity can be set in a wide range of values, and for a female artist  602 , the intensity can be set in a narrow range of values. 
     Furthermore, perceptual sensitivity varies depending on the position of the body, and in addition, the perceptual sensitivity varies from person to person. In view of this, in the embodiment, data (for example, a sensitivity coefficient) or the like indicating the perceptual sensitivity for each position of the body of the artist  602  is stored as the distributor profile  244 , and the generation unit  218  refers to the information on the distributor profile  244  and appropriately adjusts the intensity or the like set by the viewer  600  as appropriate for the artist  602 . In this way, it is possible to avoid causing discomfort to the artist  602  due to the tactile stimulus edited by the viewer  600 . 
     Furthermore, in the embodiment, the viewer  600  can also set the control command so as to present a tactile stimulus in a case where a predetermined condition is satisfied. For example, in a case where a predetermined condition is satisfied, such as a case where a predetermined time designated in the control command is reached, a case where the artist  602  utters a predetermined keyword designated in the control command (for example, the utterance of the artist  602  is detected by a microphone of the tactile presentation device  100 ), or a case where the artist  602  performs a predetermined operation designated in the control command (for example, the movement of the artist  602  is detected by the camera  120 ), the server  200  may distribute a tactile control signal related to the control command to the tactile presentation device  100 . The predetermined conditions can be set by the viewer  600 , for example. Furthermore, in the embodiment, the viewer  600  can also set the form, size, display speed, animation display speed, and the like of a virtual object displayed at the time of the presentation of the tactile stimulus. 
     Furthermore, in the embodiment, not only the tactile stimulus is edited and set by the operation on the position selection screen, the edit screen, or the like as described above, but also, various sensors (second sensors) or other devices built in the user terminal  300  may be used, for example. 
     In the embodiment, for example, the viewer  600  may edit the waveform, intensity change, or the like of the tactile stimulus by performing a touch operation such as vibrating the user terminal  300  or a motion operation such as changing the held angle of the user terminal  300 . Specifically, in the embodiment, the gyro sensor  326  and the acceleration sensor  328  built in the user terminal  300  detects the motion operation, and the viewer side input unit  214  of the server  200  acquires the detected sensing data. Furthermore, the generation unit  218  of the server  200  generates a waveform or the like on the basis of the acquired sensing data. 
     More specifically, for example, the viewer  600  causes the gyro sensor  326  and the acceleration sensor  328  built in the user terminal  300  to detect motion having predetermined rhythm. The server  200  then sets the frequency of the tactile stimulus on the basis of the rhythm extracted from the sensing data detected by the gyro sensor  326  and the acceleration sensor  328 . Furthermore, for example, the viewer  600  utters a voice with predetermined rhythm to the user terminal  300 , and causes the microphone (sound sensor)  324  built in the user terminal  300  to detect the utterance. The server  200  then uses the sensing data detected by the microphone  324  to set the frequency of the tactile stimulus. Furthermore, for example, the viewer  600  causes the camera (imaging device)  322  built in the user terminal  300  to capture an image of his/her motion. The server  200  may analyze the image captured by the camera  322 , extract predetermined motion, and generate waveform data of the tactile stimulus by using the extracted motion. 
     Furthermore, in the embodiment, the camera  322  built in the user terminal  300  captures an image of a part of the body, and the server  200  may set a perceptual location according to a location contained in the captured image, and, in such case, the location of the body may be identified on the basis of the outer shape information by the ToF sensor (not illustrated) included in the camera  322 . Furthermore, at this time, the intensity of the tactile stimulus may be set according to the angle of view of the captured image. For example, the intensity is set high for a narrow angle of view, and the intensity is set low for a wide angle of view. Furthermore, in a case where, for example, the camera  322  captures an image of a hand of the viewer  600  moving on a part (e.g., arm) of the body of the viewer  600 , the arm may be set as the perceptual location. 
     Furthermore, in the embodiment, the setting terminal is not limited to the user terminal  300 , and the setting terminal may be an electronic musical instrument having a musical instrument digital interface (MIDI), a turntable, a game interface (stick type or the like), for example. 
     In a case where a plurality of viewers  600  intends to simultaneously perform editing and inputting, the server  200  may restrict the plurality of viewers  600  to sequentially perform editing and inputting, or may restrict the plurality of viewers  600  to sequentially perform editing and inputting according to the order in which the viewers  600  have started editing or the order of the amount the viewers  600  have paid. Furthermore, the server  200  may notify the viewers  600  waiting for their turn to perform editing and inputting about how long it will take for the corresponding viewer  600  to have his/her turn (see  FIG.  16   ). 
     Furthermore, in a case where the server  200  refers to the information of the distributor profile  244  and determines that the tactile stimulus edited by the viewer  600  is a tactile stimulus that the artist  602  refuses to receive or is close thereto (NG determination), the server  200  may stop sending the tactile control signal. In such a case, the server  200  can notify the corresponding viewer  600 , an operator of the information processing system  10 , or the like that the tactile stimulus edited by the viewer  600  corresponds to the tactile stimulus that the artist  602  refuses to receive, or can give money back to the corresponding viewer  600 . Alternatively, in such a case, the server  200  may adjust the perceptual location, intensity, and the like such that the tactile stimulus edited by the viewer  600  no longer corresponds to the tactile stimulus that the artist  602  refuses to receive. 
     Furthermore, in the embodiment, in a case where the viewer  600  intends to check the tactile stimulus edited by himself/herself, the viewer  600  may check the tactile stimulus before transmission to the tactile presentation device  100  worn by the artist  602 . 
     For example, in a case where the tactile presentation device  100  is worn on the body of the viewer  600 , the server  200  sends, to the tactile presentation device  100 , a tactile control signal that is identical to the tactile control signal related to the edited tactile stimulus, which enables the viewer  600  to check the tactile stimulus edited by himself/herself via the tactile presentation device  100  worn by the viewer  600 . 
     Furthermore, in a case where the tactile presentation device  100  is not worn on the body of the viewer  600 , the user terminal  300  may be used for the check. In such a case, the server  200  generates a control signal (user terminal control signal) corresponding to the tactile control signal related to the edited tactile stimulus on the basis of the functional information (attribute information) of the user terminal  300 , and sends the control signal to the user terminal  300 . The user terminal  300  can then, according to the control signal received, output a sound from the speaker (sound output device)  306 , cause light to blink in the display unit (blinking device)  302 , or cause a vibration device (not illustrated) to vibrate, which enables checking by the viewer  600 . 
     Furthermore, in the embodiment, the tactile stimulus edited by the viewer  600  may be exchanged between the plurality of viewers  600  as the stamp  700  with tactile stimulus effect. 
     4. Third Embodiment 
     Meanwhile, as illustrated in  FIG.  15    which is an explanatory diagram for explaining the third embodiment of the present disclosure, a plurality of viewers  600  sometimes sends, to one artist  602 , stamps  700  with tactile stimulus effect simultaneously. In such a case, in a case where a plurality of tactile stimuli is simultaneously presented to the artist  602  according to the stamps  700  sent simultaneously, the artist  602  may experience discomfort due to the plurality of tactile stimuli. Furthermore, if tactile stimuli are given at the same time, the artist  602  cannot perceive the tactile stimuli individually and cannot take action for each tactile stimulus. This makes it difficult for the viewer  600  to feel as if he/she directly interacts with the artist  602  via the tactile stimulus by the stamp  700  that the viewer  600  has sent. 
     In view of this, in the third embodiment of the present disclosure, in order to avoid the discomfort and the situation where the individual tactile stimuli cannot be perceived, in a case where a plurality of viewers  600  simultaneously sends a plurality of stamps  700  with tactile stimulus effect, processing as described below is performed. The processing according to the embodiment is described with reference to  FIGS.  16  to  20   .  FIG.  16    is an explanatory diagram for explaining a display example according to the third embodiment of the present disclosure, and  FIGS.  17  to  20    are explanatory diagrams for explaining the third embodiment of the present disclosure. 
     For example, in the embodiment, as illustrated in  FIG.  17   , in a case where a plurality of viewers  600  sends a plurality of control commands  702  (or, stamps  700 ), the server  200  temporarily stores the control commands  702 , sequentially performs processing in the order that the control commands  702  have been inputted (predetermined rule), generates a tactile control signal, and sends the tactile control signal to the tactile presentation device  100 . In the embodiment, in a case where the plurality of viewers  600  sends the plurality of control commands  702 , the server  200  may temporarily stop acquiring the plurality of control commands  702  and sequentially acquire the control commands  702  in the order that the control commands  702  have been inputted. In such a case, as illustrated in  FIG.  16   , the server  200  may display, for the viewer  600  waiting for his/her turn, a display  818  for notifying the viewer  600  about how long it will take for the viewer  600  to have his/her turn via the display unit  302  of the user terminal  300 . 
     As described above, in the embodiment, since the tactile stimuli are sequentially presented to the artist  602 , the artist  602  can avoid experiencing discomfort, and since the tactile stimuli can be individually perceived, action can be taken for each tactile stimulus. 
     Furthermore, in the embodiment, as illustrated in  FIG.  18   , in a case where a plurality of control commands  702  (or, stamps  700 ) is acquired within a predetermined time, the server  200  may adjust, for example, the intensity of the tactile stimulus or the like according to the number of control commands  702  acquired, generate a tactile control signal as one tactile stimulus, and send the tactile control signal to the tactile presentation device  100 . For example, the server  200  increases the intensity of the tactile stimulus as the number of identical control commands  702  acquired (for example, identical in perceptual location, waveform type, and so on) increases. In addition to simply increasing the intensity in accordance with the number of control commands  702  acquired, an upper limit of the intensity may be set or the intensity may be processed by subtraction in consideration of the burden on the artist  602  or the like. 
     Furthermore, in the embodiment, the server  200  may change the waveform of the tactile stimulus, may adjust the presentation time, or may adjust the perceptual location according to the number of acquired control commands  702 , and the present disclosure is not particularly limited to this example. Furthermore, in the embodiment, on the basis of the perceptual locations designated in the control commands  702  continuously acquired for example, the perceptual location may be adjusted to one perceptual location and a tactile control signal as one tactile stimulus may be generated. More specifically, in a case where the right shoulder and the left shoulder are designated as the perceptual locations in the control commands  702  continuously acquired, the server  200  sets a neck line between the right shoulder and the left shoulder as the perceptual location in the generated tactile control signal. 
     Furthermore, in the embodiment, as illustrated in  FIG.  19   , the server  200  may perform the processing in the order according to the amount paid by the viewer  600  at the time of input of the control command  702  (or, stamp  700 ) (predetermined rule). For example, the server  200  prioritizes a control command  702  with a high amount paid at the time of input of the control command  702 . That is, since the viewer  600  purchases priority of interaction with the artist  602 , the viewer  600  who intends to early interact with the artist  602  pays more money. In other words, this order of processing can motivate the viewer  600  to pay more money. 
     Furthermore, in the embodiment, as illustrated in  FIG.  20   , in a case where a plurality of identical control commands  702  (or, stamps  700 ) is acquired within a predetermined time, the server  200  may increase, for example, the intensity of presentation of the tactile stimulus sequentially according to the order of the control commands  702  acquired. In this way, collaboration, or interaction, between the plurality of viewers  600  can be encouraged, resulting in acquiring higher value-added experiences. 
     Furthermore, in the embodiment, the server  200  may adjust the tactile stimulus according to the synchronicity of the transmission of the plurality of control commands  702  (or, stamps  700 ) of the plurality of viewers  600 . More specifically, in a case where the control commands  702  having the same content are synchronously sent from different viewers  600  (so-called execution of “mission” by the plurality of viewers  600 ), the server  200  may adjust the intensity of the tactile stimulus according to the degree of synchronicity. Furthermore, in the embodiment, the server  200  may generate and send the tactile control signal only in a case where the number of control commands  702  having the same content acquired from different viewers  600  exceeds a predetermined number (predetermined condition). Alternatively, the server  200  may generate and send the tactile control signal only in a case where the type of the plurality of control commands  702  acquired from different viewers  600  is of a predetermined type. 
     Furthermore, in the embodiment, in a case where control commands  702  (or, stamps  700 ) for designating a plurality of identical perceptual locations are continuously acquired within a predetermined time, and where the control commands  702  are directly presented as-is to the artist  602  as a plurality of tactile stimuli, the artist  602  may experience discomfort due to the plurality of tactile stimuli. In view of this, in the embodiment, the server  200  (specifically, the viewer side input unit  214 ) may receive and process only a control command  702  that designates a perceptual location away, by a predetermined distance, from the perceptual location presented immediately before. 
     Furthermore, in the embodiment, for example, in a case where a plurality of viewers  600  sends a plurality of control commands  702  (or, stamps  700 ), the server  200  basically acquires the control commands  702  sequentially in the order that the control commands  702  have been inputted; however, in a case where the amount of the control command  702  to be acquired next (amount paid at the time of input of the control command  702 ) is equal to or more than a predetermined amount, the server  200  may stop the processing on the control command  702  acquired before on the way, and preferentially process the next control command  702  that is equal to or more than the predetermined amount. Alternatively, in the embodiment, in a case where a plurality of viewers  600  sends a plurality of control commands  702  (or, stamps  700 ), the server  200  basically acquires the control commands  702  sequentially in the order that the control commands  702  have been inputted; however, the server  200  may compare the amount of the previous control command  702  with the amount of the next control command  702 , and, in a case where the amount of the next control command  702  is equal to or lower than the amount of the previous control command  702 , the server  200  may proceed with the processing of the previous control command  702 . 
     Furthermore, in the embodiment, in a case where the amount of the next control command  702  is higher than that of the previous control command  702 , the server  200  may stop the processing of the control command  702  previously obtained on the way, and preferentially process the next control command  702 . In addition, in the embodiment, in a case where, during the processing of the next control command  702 , a control command  702  that is more expensive than the next control command  702  (control command  702  after the next control command  702 ) is sent, the server  200  may stop the processing of the next control command  702  on the way, and preferentially process the control command  702  after the next control command  702 . 
     5. Fourth Embodiment 
     Furthermore, in the fourth embodiment of the present disclosure, the price of the stamp  700  with tactile stimulus effect may be dynamically determined according to the contact rate between the tactile presentation device  100  and the body of the artist  602 , the perceptual location, the attribute information of the viewer  600  or the artist  602 , and the like. In the embodiment, the price of the stamp  700  is determined according to the value of the experience felt by the viewer  600  due to the determination of the price of the stamp  700  in accordance with such conditions, which can convince and satisfy the viewer  600  of the purchase of the stamp  700 . 
     5.1 Detailed Configuration of Server  200   a    
     First, an example of the detailed configuration of the server  200   a  according to the embodiment is described with reference to  FIG.  21   .  FIG.  21    is a diagram illustrating an example of the functional configuration of the server  200   a  according to the embodiment. As illustrated in  FIG.  21   , the server  200   a  mainly includes the communication unit  202 , a control unit  210   a , and a storage unit  240   a  as with the first embodiment. The individual functional blocks of the server  200   a  are sequentially described below; however, since the communication unit  202  is common to that of the first embodiment, the description thereof is omitted here. 
     (Control Unit  210   a ) 
     The control unit  210   a  is a controller, and as illustrated in  FIG.  21   , the control unit  210   a  includes the GUI control unit  212 , the viewer side input unit  214 , the distributor side input unit  216  (not illustrated in  FIG.  21   ), the generation unit  218 , and the output control unit (first distribution unit)  222  as with the first embodiment, and further includes a price determination unit  224  and a settlement unit  226 . Note that, since the GUI control unit  212 , the viewer side input unit  214 , the distributor side input unit  216 , the generation unit  218 , and the output control unit  222  are common to those of the first embodiment, the description thereof is omitted here, and only the price determination unit  224  and the settlement unit  226  are described. 
     Price Determination Unit  224   
     The price determination unit  224  determines a price of the stamp  700  (or, for the input of the control command  702 ) on the basis of the positional information and the mode information included in the control command  702  correlated with the stamp  700  acquired, the contact rate between the body of the artist  602  and the tactile presentation device  100  acquired from the distributor side input unit  216  (not illustrated in  FIG.  21   ), or the attribute information of the viewer  600  or the artist  602  acquired from the storage unit  240   a . At this time, the price determination unit  224  may determine the price with reference to information in a price data DB  248  stored in the storage unit  240   a  described later. 
     Settlement Unit  226   
     For example, in a case where the settlement unit  226  receives a settlement command from the user terminal  300  via the communication unit  202 , the settlement unit  226  makes a settlement related to the purchase of the stamp  700  (or, for the input of the control command  702 ) on the basis of the price determined by the price determination unit  224 . 
     (Storage Unit  240   a ) 
     As illustrated in  FIG.  21   , the storage unit  240   a  includes the viewer profile  242 , the distributor profile  244 , and the distribution data DB  246  as with the first embodiment, and further includes the price data DB  248  for storing information used to determine a price of the stamp  700  (or, for the input of the control command  702 ). 
     Although the example of the detailed configuration of the server  200   a  according to the embodiment has been specifically described above, the detailed configuration of the server  200   a  according to the embodiment is not limited to the example illustrated in  FIG.  21   , and, for example, the server  200   a  may further include the determination unit  220  as with the first embodiment. 
     5.2 Information Processing Method 
     The server  200   a  according to the embodiment is described above. Next, an example of the information processing method according to the embodiment is described with reference to  FIG.  22   .  FIG.  22    is a flowchart of an example of an information processing method according to the embodiment. As illustrated in  FIG.  22   , the information processing method according to the embodiment includes a plurality of steps from Step S 201  to Step S 208 . The details of the steps included in the information processing method according to the embodiment are described below. 
     First, the viewer  600  selects one stamp  700  with tactile stimulus effect from the stamps  700  with tactile stimulus effect displayed on the display unit  302  of the user terminal  300 , and sends the selected stamp  700  to the server  200   a . The server  200   a  then acquires information on the stamp  700  with tactile stimulus effect that is sent from the user terminal  300 , selected by the viewer  600 , and is correlated with the control command  702  (Step S 201 ) as with Step S 101  of the first embodiment. 
     Next, the server  200   a  refers to the information of the price data DB  248 , and determines the price of the stamp  700  in accordance with the positional information and the mode information included in the control command  702  acquired, the contact rate between the tactile presentation device  100  and the body of the artist  602 , or the attribute information of the viewer  600  or the artist  602  (Step S 202 ). Details of the determination of the price are described later as an example. 
     Then, in a case where a settlement command is received from the user terminal  300 , the server  200   a  makes a settlement related to the purchase of the stamp  700  on the basis of the price determined in Step S 202  (Step S 203 ). At this time, the server  200   a  preferably notifies the viewer  600  of the availability of the settlement processing. 
     Next, the server  200   a  performs the processing from Step S 204  to Step S 208 , which is similar to Step S 102  to Step S 106  in the first embodiment illustrated in  FIG.  8   , and thus the description thereof is omitted here. Note that, in the embodiment, the settlement processing in Step S 203  may be performed only in a case where Step S 207  (NG determination) of  FIG.  22    is performed and it is determined that the generated tactile control signal is to be sent to the tactile presentation device  100 , that is, the steps may not be performed in the order illustrated in  FIG.  22   . 
     5.3 Example 
     The embodiment is described above. Next, an example of the embodiment is described more specifically with reference to  FIGS.  23  to  25   , illustrating specific examples.  FIGS.  23  to  25    are explanatory diagrams for explaining a display example according to an example of the embodiment. Note that the following examples are merely examples of the embodiment, and the embodiment is not limited to the following examples. 
     Example 1 
     Meanwhile, depending on the body shape of the artist  602 , contact between the tactile stimulus unit  106  of the tactile presentation device  100  and the body of the artist  602  may be poor, and the tactile stimulus may not be presented as intended by the viewer  600 . Then, in a case where a tactile stimulus that is presented as intended and a tactile stimulus that is not presented as intended are set at a uniform price, it may cause a feeling of unfairness to the viewer  600 . In view of this, in the example, in order to avoid such unfairness, a tactile stimulus that is presented as intended and a tactile stimulus that is not presented as intended are set at different prices. Specifically, in the example, the server  200   a  determines the price of the stamp  700  (or, for the input of the control command  702 ) on the basis of sensing data of a worn state detection sensor for detecting a worn state (for example, a zipper-type sensor, a pressure sensor, or the like) (not illustrated) of the tactile presentation device  100 . For example, in a case where the control command  702  correlated with the selected stamp  700  includes a command to use the tactile stimulus unit  106  having a high contact rate with the body of the artist  602 , the server  200   a  sets the price of the stamp  700  higher. On the other hand, in a case where the control command  702  includes a command to use the tactile stimulus unit  106  having a low contact rate with the body of the artist  602 , the server  200   a  sets the price of the stamp  700  lower. It is assumed that, in the example, the sensing data of the worn state detection sensor can be imported into the server  200   a , for example, with detection that the artist  602  has worn the tactile presentation device  100  used as a trigger. 
     Example 2 
     In the example, since each artist  602  has a perceptual location with high perceptual sensitivity to a tactile stimulus and a perceptual location with low perceptual sensitivity to a tactile stimulus, the server  200   a  determines the price of the stamp  700  for the tactile stimulus presented at each perceptual location according to the difference in perceptual sensitivity for each perceptual location. For example, in a case where the control command  702  correlated with the selected stamp  700  includes a command to use the tactile stimulus unit  106  that is present at a perceptual location with high perceptual sensitivity, the server  200   a  sets the price of the stamp  700  higher. On the other hand, in a case where the control command  702  includes a command to use the tactile stimulus unit  106  that is present at a perceptual location with low perceptual sensitivity, the server  200   a  sets the price of the stamp  700  lower. In view of this, in the example, the server  200   a  stores an index or the like indicating the perceptual sensitivity for each perceptual location of the artist  602  as the distributor profile  244 , and determines the price of the stamp  700  (or, for the input of the control command  702 ) on the basis of the index stored. Furthermore, the example is not limited to the determination of the price according to the perceptual sensitivity, and for example, the price may be determined according to popularity (which can be estimated on the basis of the frequency of selection or the like) among the viewer  600  or the artist  602  for the stamp  700  or the tactile stimulus (waveform, perceptual location, etc.), and the present disclosure is not particularly limited to this example. 
     Example 3 
     In the example, the server  200   a  determines the price of the stamp  700  (or, for the input of the control command  702 ) according to the attribute information (for example, a purchase record, a membership rank, a membership course, and the like) of the viewer  600 . For example, in the example, the server  200   a  stores, as the viewer profile  242 , the amount of money that the viewer  600  has paid so far for the purchase of the stamp  700  in correlation with the identification information of the viewer  600 , and determines the price of the stamp  700  (or, for the input of the control command  702 ) newly purchased by the viewer  600  on the basis of the total amount stored. In the example, the server  200   a  may, for example, set the purchase price of the stamp  700  lower the more money the viewer  600  has paid so far, or alternatively, may set the purchase price of the stamp  700  higher the more money the viewer  600  has paid so far. Furthermore, the example is not limited to the determination of the price according to the amount purchased so far, and for example, the price may be determined according to a membership rank that is set according to the amount purchased so far, or a membership course (e.g., trial course, new membership course, advanced course, and the like) to which the viewer  600  subscribes before purchasing the stamp, and the present disclosure is not particularly limited to this example. At this time, the server  200   a  may display, on the display unit  302  of the user terminal  300 , a screen as illustrated in  FIG.  23    as the selection screen of the stamp  700 . The screen shows, for example, the price of the stamp  700 , the membership rank of the viewer  600 , and purchase points given to the viewer  600  according to his/her purchase record. 
     Furthermore, in the example, the range of the waveform type, intensity, perceptual location, and the like of the tactile stimulus selectable by the viewer  600  may be determined according to not only the price but also the attribute information (e.g., purchase record, membership rank, membership course, and the like) of the viewer  600 . For example, the server  200   a  sets the upper limit of selectable tactile stimulus larger the more money the viewer  600  has paid so far. Furthermore, in the example, the server  200   a  may set to give priority to the order in which the stamp  700  can be sent according to not only the selectable range but also the attribute information of the viewer  600 . For example, the server  200   a  gives priority to the order in which the stamp  700  can be sent as the amount of money paid by the viewer  600  so far is larger. At this time, the server  200   a  may display, on the display unit  302  of the user terminal  300 , a screen as illustrated in  FIG.  24    as the selection screen of the stamp  700 . On the screen, for example, buttons for upgrading the position and the order are displayed, and for example, in a case where the viewer  600  performs an operation on the button for upgrading the position, the screen transitions to a position selection screen as illustrated in  FIG.  25   . On the position selection screen, the human body model display  812  is shown, and on the human body model display  812 , a region  814  corresponding to the tactile stimulus unit  106  selectable by the viewer  600  is shown, and the price thereof is also displayed. The viewer  600  can select a desired tactile location by performing an operation on the region  814  while checking the price on the position selection screen. In the example described above, it is possible to provide a mechanism for preferentially treating the viewer  600  who has purchased a large amount of stamps  700  or has paid a large amount of money for example, which can further motivate the viewer  600  to purchase the stamp  700 . 
     6. Fifth Embodiment 
     Furthermore, in the embodiment, the stamp  700  with tactile stimulus effect can be exchanged among the plurality of viewers  600  or collected by the viewer  600 , which can further motivate the viewer  600  to purchase the stamp  700 . 
     Specifically, in the embodiment, for example, during streaming of performance video of the artist  602 , the selection screen for the stamp  700  with tactile stimulus effect or the stamp  700  itself is automatically distributed to the user terminal  300  of the viewer  600 . The viewer  600  is then encouraged to send the stamp  700  to the artist  602  during streaming. Furthermore, it is possible to distribute, to the viewer  600 , a valuable stamp  700  with tactile stimulus effect which is not normally distributed (so-called “rare stamp”), which means limiting the location and the date and time of the distribution (e.g., limiting to the date and time when the artist is performing at a live concert venue). In this way, the viewers  600  visit a live concert venue, for example, in order to obtain rare and valuable stamps  700 , which improves the ability of the live concert venue to attract customers. Note that, only during streaming, the viewer  600  may be able to automatically acquire the rare stamp by communication connection or may be able to acquire the rare stamp by performing processing such as purchase procedure, and the present disclosure is not particularly limited to this example. 
     Furthermore, the stamps  700  with tactile stimulus effect acquired via such a stamp selection screen may be exchanged among the plurality of viewers  600  via a social networking service (SNS), or the number and types of collected stamps  700  may be published as ranking. For example, in the embodiment, the server  200  stores, as the viewer profile  242 , information on the stamps  700  acquired by the viewer  600  so far in correlation with the identification information of the viewer  600 . Furthermore, in the embodiment, in a case where a predetermined type of stamp  700  with tactile stimulus effect can be collected (in a case where a predetermined condition is satisfied), the server  200  may give a new stamp  700  with tactile stimulus effect (e.g., “rare stamp”) to the viewer  600 . In this way, the viewer  600  collects and purchases a predetermined type of stamp in order to obtain a valuable stamp  700 , which can further motivate the viewer  600  to purchase the stamp  700 . 
     7. Sixth Embodiment 
     Furthermore, in the embodiment, it is possible to further motivate the viewer  600  to purchase a stamp  700  with tactile stimulus effect by adding a game element. 
     7.1 Detailed Configuration of Server  200   b    
     First, the detailed configuration of the server  200   b  according to the embodiment is described with reference to  FIG.  26   .  FIG.  26    is a diagram illustrating an example of the functional configuration of the server  200   b  according to the embodiment. As illustrated in  FIG.  26   , the server  200   b  mainly includes the communication unit  202 , a control unit  210   b , and the storage unit  240   a  as with the first and fourth embodiments. The individual functional blocks of the server  200   b  are sequentially described below; however, since the communication unit  202  and the storage unit  240   a  are common to those of the first and fourth embodiments, the description thereof is omitted here. 
     (Control Unit  210   b ) 
     The control unit  210   b  is a controller, and as illustrated in  FIG.  26   , the control unit  210   b  includes the GUI control unit  212 , the viewer side input unit  214 , the distributor side input unit  216 , the generation unit  218 , and the output control unit (first distribution unit)  222  as with the first embodiment, and further includes a point giving unit  228 . Note that, since the GUI control unit  212 , the viewer side input unit  214 , the distributor side input unit  216 , the generation unit  218 , and the output control unit  222  are common to those of the first embodiment, the description thereof is omitted, and only the point giving unit  228  is described below. 
     Point Giving Unit  228   
     The point giving unit  228  acquires an evaluation for the tactile stimulus that is inputted by the artist  602  who has perceived the tactile stimulus via the distributor side input unit  216 , and grants a point to the viewer  600  according to the acquired evaluation. Note that the granted point is stored in the viewer profile  242  of the storage unit  240   a  in correlation with the identification information of the viewer  600 . 
     7.2 Embodiment 
     The server  200   b  according to the embodiment is described above. Next, the embodiment is described with reference to  FIGS.  27  and  28   .  FIGS.  27  and  28    are explanatory diagrams for explaining a display example according to the embodiment. 
     Here, a game is assumed, for example, in which two viewers  600  throw (send) stamps  700  with tactile stimulus effect to one artist  602  and compete with each other for evaluation. First, the artist  602  evaluates tactile stimuli by the stamps  700  thrown, and the server  200   b  gives a point to each viewer  600  in accordance with the evaluation. The server  200   b  then may determine the win or lose of the two viewers  600  according to the number of points granted, and display, on the display unit  302  of the user terminal  300 , a screen as illustrated in  FIG.  27    as a screen indicating the win or lose result. Furthermore, as illustrated in  FIG.  28   , the server  200   b  may show, after a series of such matches, a ranking based on the total number of points granted to each viewer  600 . 
     Furthermore, in the embodiment, the evaluation by the artist  602  is not limited to the one manually entered by the artist  602 , and for example, may be an evaluation based on sensing data of a biometric information sensor (not illustrated) attached to the body of the artist  602 . For example, the larger the increase in heart rate of the artist  602  caused by the tactile stimulus is, the higher evaluation is given. Note that, in the embodiment, the sensing data by the biometric information sensor of the artist  602  may be displayed on the user terminal  300 , for example. 
     As described above, in the embodiment, it is possible to further motivate to purchase a stamp  700  with tactile stimulus effect by adding a game element. 
     7.3 Modification Example 1 
     Furthermore, in the embodiment, a game including the artist  602  can be so configured that, not only in a case where the viewer  600  throws the stamp  700  with tactile stimulus effect, but also in a case where the artist  602  performs a predetermined operation in response to the stamp  700  thrown, a tactile stimulus related to the stamp  700  is not presented. Hereinafter, a modification example related to such a game is described. 
     (Detailed Configuration of Server  200   c ) 
     First, the detailed configuration of the server  200   c  according to the modification example is described with reference to  FIG.  29   .  FIG.  29    is a diagram illustrating an example of the functional configuration of the server  200   c  according to the modification example. As illustrated in  FIG.  29   , the server  200   c  mainly includes the communication unit  202 , a control unit  210   c , and the storage unit  240  as with the first embodiment. The individual functional blocks of the server  200   c  are sequentially described below; however, since the communication unit  202  and the storage unit  240  are common to those of the first embodiment, the description thereof is omitted and only the control unit  210   c  is described. 
     The control unit  210   c  is a controller, and as illustrated in  FIG.  29   , the control unit  210   c  includes the GUI control unit  212 , the viewer side input unit  214 , the distributor side input unit  216 , the generation unit  218 , the determination unit  220 , and the output control unit (first distribution unit)  222  as with the first embodiment. Furthermore, in the modification example, the distributor side input unit  216  acquires, for example, sensing data and the like of various sensors of the tactile presentation device  100 , and outputs the sensing data and the like to the determination unit  220 . 
     (Information Processing Method) 
     The server  200   c  according to the modification example is described above. Next, an information processing method according to the modification example is described with reference to  FIGS.  30  and  31   .  FIG.  30    is a flowchart of an example of an information processing method according to a modification example to the embodiment, and  FIG.  31    is an explanatory diagram for explaining a display example according to the modification example to the embodiment. As illustrated in  FIG.  30   , the information processing method according to the modification example includes a plurality of steps from Step S 301  to Step S 308 . The details of the steps included in the information processing method according to the modification example are described below. 
     First, the server  200   c  performs the processing from Step S 301  to Step S 304 , which is similar to Step S 101  to Step S 104  in the first embodiment illustrated in  FIG.  8   , and thus the description thereof is omitted here. 
     Next, the server  200   c  displays, on the display unit  302  of the user terminal  300  and the display unit (not illustrated) of the monitor  110 , an icon of a coin and the trajectory  808  along which the icon moves from the viewer  600  side to the artist  602  as illustrated in  FIG.  31   , for example, in augmented reality (AR) (Step S 305 ). Note that, in the modification example, the viewer  600  can set the trajectory  808  and a speed at which the trajectory  808  is displayed before throwing the stamp  700  with tactile stimulus effect, or can modify the same after the display. Furthermore, in the modification example, a predetermined sound may be outputted from a speaker (not illustrated) or the like of the user terminal  300  or the monitor  110  at the time of AR display. 
     Then, the artist  602  visually recognizes the trajectory  808  displayed on the display unit (not illustrated) or the like of the monitor  110  and acts in response thereto (e.g., escaping from the fall position of the icon estimated from the trajectory  808 , performing a touch operation on a predetermined terminal (e.g., the monitor  110 ), uttering a keyword, and so on). Next, the server  200   c  acquires sensing data regarding the action of the artist  602  (Step S 306 ). For example, the escaping motion of the artist  602  can be detected by the camera  120 , the touch operation can be detected by a touch panel (not illustrated) of the monitor  110 , and the utterance of the artist  602  can be detected by a microphone (not illustrated) of the tactile presentation device  100 . 
     Next, the server  200   c  determines whether or not to present a tactile stimulus in the tactile presentation device  100  on the basis of the sensing data acquired in Step S 306  (Step S 307 ). For example, the server  200   c  determines not to present the tactile stimulus in a case where the artist  602  performs an escaping operation at predetermined timing, in a case where the timing of the touch operation of the artist  602  is predetermined timing, or in a case where the utterance of the artist  602  is a predetermined keyword (e.g., get out of here, as illustrated in  FIG.  31   ). Furthermore, in the modification example, in a case where a predetermined number of stamps  700  or more (or, control command  702 ) are simultaneously sent, a tactile stimulus may be presented even in a case where a predetermined motion of the artist  602  is detected. Furthermore, in the modification example, when the viewer  600  throws the stamp  700  with tactile stimulus effect, a desired keyword can be inputted or selected, and the keyword may be displayed on the monitor  110 . In such a case, in a case where it is detected that the artist  602  has correctly uttered the keyword displayed on the monitor  110 , the server  200   c  may determine not to present or to present the tactile stimulus. In this way, according to the modification example, the viewer  600  can not only have a unidirectional experience such as watching the performance of the artist  602 , but can also have a real-time, interactive, and higher value-added experience such as interacting with the artist  602 . 
     Then, the server  200   c  performs the processing of Step S 308 , which is similar to Step S 106  in the first embodiment illustrated in  FIG.  8   , and thus the description thereof is omitted here. 
     In the modification example, not only viewers  600  but also the artist  602  can play a kind of virtual game such as a dodgeball-like game, throwing the stamps  700  each other and avoiding the thrown stamps  700 . As a result, the viewer  600  can feel as if he/she directly interacts with the artist  602  in a thrilling manner, and can obtain a higher value-added experience. 
     Note that the modification example is not limited to not presenting the tactile stimulus in a case where the predetermined motion of the artist  602  is detected, and the intensity or the like of the tactile stimulus may be changed in a case where the predetermined motion of the artist  602  is detected. Furthermore, in a case where no tactile stimulus is presented, a predetermined sound (e.g., an extinction sound or the like) may be outputted via the user terminal  300 , or the user terminal  300  may be vibrated. Furthermore, in the modification example, the server  200   c  may determine whether or not to present a tactile stimulus according to a combination of the type of the stamp  700 , the attribute information of the artist  602 , the attribute information of the viewer  600 , and the like. 
     7.4 Modification Example 2 
     Furthermore, the game element may be further enhanced by a configuration in which when the viewer  600  throws the stamp  700  with tactile stimulus effect, the content of the stamp  700  to be thrown may be determined in consideration of chance and skill. Such a modification example is described with reference to  FIG.  32   .  FIG.  32    is an explanatory diagram for explaining a display example according to the modification example to the embodiment. 
     In the modification example, for example, it is assumed that the intensity of the tactile stimulus is determined by a value of a level meter when the stamp  700  with tactile stimulus effect is thrown. Specifically, as illustrated in  FIG.  32   , an animation of a cursor  820  for designating the intensity of the tactile stimulus is displayed on the display unit  302  of the user terminal  300 . In the animation, it is assumed that the cursor  820  always moves left and right. Furthermore, an icon  822  such as a bow and arrow is displayed on the display unit  302 , for example. The viewer  600  can throw the stamp  700  by swiping the icon  822  and releasing the fingertip from the screen. The viewer side input unit  214  of the server  200   c  then acquires the intensity corresponding to the position of the cursor  820  when the release operation is performed as the intensity of the tactile stimulus related to the thrown stamp  700 . 
     In the modification example, the intensity to be set is determined by chance because the cursor  820  is always moving left and right. In addition, in order to set the intensity to a desired level, the viewer  600  needs to carefully perform operation on the icon  822  based on the movement of the cursor  820 , which requires skill. Therefore, in a case where the viewer  600  cannot set the intensity to the desired level, for example, the viewer  600  throws the stamp  700  over and over again until the desired intensity can be set. That is, since the modification example provides a game with both skill and chance, it is possible to provide the viewer  600  with a more entertaining experience. 
     Note that the modification example is not limited to the operation on the icon  822 , and for example, the intensity of the tactile stimulus or the like may be set according to the speed of the motion operation, by the viewer  600 , for changing the held angle of the user terminal  300 , and the present disclosure is not particularly limited to this example. Furthermore, in the modification example, the cursor  820  is not limited to an animation, and may be a cursor  820  that can be moved in response to the operation by the viewer  600 . In such a case, the viewer side input unit  214  of the server  200   c  acquires the intensity corresponding to the position to which the cursor  820  has been moved in response to the operation of the viewer  600  as the intensity of the tactile stimulus related to the thrown stamp  700 . 
     7.5 Modification Example 3 
     In the embodiments and modification examples of the present disclosure, there is sometimes a noise due to vibrations of the tactile stimulus unit  106  of the tactile presentation device  100  in a microphone (not illustrated) provided on a shoulder part of the tactile presentation device  100 . In view of this, a modification example for canceling a noise due to vibrations of the tactile stimulus unit  106  in the microphone is described below. 
     Specifically, the server  200  predicts a noise according to a waveform given to the tactile stimulus unit  106 . For example, the server  200  can predict a noise by referring to a database (DB) (not illustrated) obtained by applying various waveforms to the tactile stimulus unit  106  in advance and machine learning the generated noise. The server  200  then can avoid deterioration of a sound due to the noise by canceling the predicted noise from the sound collected by the microphone (not illustrated) provided on the shoulder part of the tactile presentation device  100 . 
     Note that, in the modification example, the server  200  may adjust a waveform to be canceled in accordance with a distance between the microphone (not illustrated) provided on the shoulder part of the tactile presentation device  100  and the tactile stimulus unit  106 . Furthermore, in a case where the artist  602  is performing in a studio for example, the microphone may collect a noise that is reflected on a wall of the studio. In such a case, the server  200  may adjust the waveform to be canceled in accordance with a distance between the wall and the microphone provided on the shoulder part of the tactile presentation device  100 . 
     Furthermore, in the modification example, as a means for canceling the noise caused by vibrations of the tactile stimulus unit  106 , the microphone (not illustrated) may be made directional so that the microphone intensively collects the sound of the artist  602 , or a frequency region where the microphone can collect a sound may be limited to avoid collecting the noise caused by vibrations of the tactile stimulus unit  106 . 
     8. Modification Example to Information Processing System  10  of Present Disclosure 
     Furthermore, a modification example to the information processing system  10  according to the embodiment of the present disclosure is described with reference to  FIGS.  33  to  38   .  FIGS.  33  to  38    are system diagrams illustrating an example of the schematic configuration of the information processing system  10  according to a modification example to the embodiment of the present disclosure. 
     First, in the information processing system  10  illustrated in  FIG.  33   , the server  200  illustrated in  FIG.  3    is implemented by a haptic server  250   a , a distribution data editing server  250   b , a live streaming server  250   c , and a haptic server  250   d.    
     Specifically, as illustrated in  FIG.  33   , in the information processing system  10  according to the embodiment, for example, the tactile presentation device (haptic vest)  100 , a drive amplifier/interface  140 , a speaker  116 , the monitor  110 , a microphone  124 , and the camera  120  are arranged on the artist  602  side. Furthermore, in the information processing system  10 , for example, the haptic server (information processing device)  250   a , the distribution data editing server  250   b , the live streaming server (another information processing device)  250   c , and the haptic server  250   d  are placed between the artist  602  side and the viewer  600  side. Furthermore, in the information processing system  10 , a smartphone or a tablet terminal as an example of the user terminal  300  is placed on the viewer  600  side. The individual devices included in the information processing system  10  can send and receive data via various communication networks, such as a wired/wireless local area network (LAN), Wi-Fi (registered trademark), Bluetooth (registered trademark), a mobile communication network (long term evolution (LTE), and 5G (5th generation mobile communication system). Note that the number of devices included in the information processing system  10  is not limited to the number illustrated in  FIG.  33   , and may be further greater. Furthermore, the information processing system  10  may include a device that is not illustrated in  FIG.  33   . For example, the information processing system  10  may include a general-purpose personal computer (PC), a game machine, a cell phone, a portable media player, a speaker, a projector, a display (digital signage, etc.), a wearable device such as headphones, smart glasses, or a smart watch. 
     Note that, in the information processing system  10  illustrated in  FIG.  33   , for example, the haptic server  250   a  that manages presentation of a tactile stimulus may be operated by a business operator different from a business operator of the distribution data editing server  250   b  with a built-in application for editing video and sound to be distributed to the viewer  600  and the live streaming server  250   c  that manages distribution to the viewer  600 . The following is a brief description of the drive amplifier/interface  140 , the monitor  110 , the camera  120 , the haptic server  250   a , the distribution data editing server  250   b , the live streaming server  250   c , and the haptic server  250   d  included in the information processing system  10  according to the embodiment. 
     (Drive Amplifier/Interface  140 ) 
     The drive amplifier/interface  140  is an interface that sends and receives a tactile control signal between the tactile presentation device  100  and the haptic server  250   a . For example, the drive amplifier/interface  140  acquires the profile information (functional information or the like) of the tactile presentation device  100  from the tactile presentation device  100 , or converts and amplifies a tactile control signal generated by the haptic server  250   a , and sends the signal to the tactile presentation device  100 . 
     (Monitor  110 ) 
     The monitor  110  can display, for the artist  602 , video of the artist  602  captured by the camera  120  described later for example, and the monitor  110  further can superimpose text, an icon, an animation, or the like on the image of the artist  602 .

     9. Summary 
     As described above, in the embodiment of the present disclosure, a tactile stimulus corresponding to the stamp  700  with tactile stimulus effect selected by the viewer  600  can be presented to the artist  602 . Therefore, in the embodiment, if the artist  602  perceives the presented tactile stimulus and takes action, then the viewer  600  can confirm, in real time, the action induced by the tactile stimulus presented by the stamp  700  that the viewer  600  has sent. Then, according to the embodiment, if the viewer  600  can confirm, in real time, the action induced by the tactile stimulus related to the stamp  700  that he/she has sent, then the viewer can feel as if he/she directly interacts with the artist  602 , that is, the viewer  600  can obtain a real-time, interactive, and value-added experience. 
     The embodiment of the present disclosure is applicable not only to the live streaming or the like but also to, for example, the stamp  700  or the like exchanged on the SNS. In such a case, for example, instead of the tactile presentation device  100 , the user terminal  300  can vibrate to provide a tactile stimulus to a person to whom the stamp  700  has been sent.
