Description

  The present invention relates to an information processing system that performs information processing in response to a touch of an input device on a multi-touch pad, the input device, and an information processing program that causes an electronic device to perform the information processing.

  A touch panel is a device in which a display such as a liquid crystal or an organic EL, and a multi-touch pad that detects the position of an object such as a pen or a finger by pressing, touching, or approaching them are stacked in layers. According to the touch panel, the user can touch the displayed button to cause the computer to perform a process corresponding to the button, or to draw a line or a figure at the touched position. Input operation can be performed.

  In recent years, multi-touch pads capable of detecting multi-point touches are becoming popular. According to the multi-touch pad, for example, while the first finger and the second finger are touched simultaneously on the panel, the image displayed at the touched position is enlarged by moving the fingers in the opening direction. Various input operations such as rotating an image displayed at a touched position by an operation of moving these fingers so as to rotate them on the panel can be performed.

  For example, in Patent Document 1, when a user performs a specific operation such as an operation of sliding on the panel in the shape of a hand holding a pen, the multi-touch panel is input to the multi-touch panel by the specific operation. There has been proposed an apparatus that specifies what operation the user is performing from the positional relationship between multiple points and the relationship between the magnitudes of the pressing forces and performs processing according to the specified operation.

  However, since the multi-touch pad is basically a flat surface and has no clues, the operation feeling is poor compared to a state in which an actual object is operated. In addition, there is a large separation such as a difference in dimensions between the real space where the user is operating and the virtual space displayed on the touch panel. The reality is poor.

  Therefore, a touch tool technique has been proposed in which a plurality of contact portions project from a block-shaped input device, a positional relationship between the contact portions is detected by a multi-touch pad, and information processing is executed according to the positional relationship ( For example, see Patent Document 2). The input device is a real object that a user actually touches and operates. This input device mediates the real space where the user is operating and the virtual space displayed on the touch panel, and integrates the real space and the virtual space.

Japanese Patent Laid-Open No. 2007-242035 JP 2012-090993 A

  The touch tool technology makes it difficult for the user to be confused even if various activities in the real space are replaced with the virtual space. Therefore, various applications for performing various activities in the real space in the virtual space on the computer can be expected.

  For example, the present inventor assumes that a stamp given to a customer by a store for payment of consideration for goods or services is achieved by an electronic device. When stamp card data is stored in the electronic device and the multi-touch pad is touched with the input device, the number of stamps pressed on the virtual stamp card is increased. For example, a usage form as a stamp rally can be assumed.

  Further, when an electronic device is touched with an input device, data such as electronic money and characters may be purchased. A card of a battle type card game may be used as an input device. The input device may be used for user authentication as a user seal.

  However, when the multi-touch pad is touched with the input device, a certain value may be generated. In each of the above examples, not only electronic money but also a certain number of stamps can be exchanged for services, and data such as characters and cards for competitive card games also have merchandise value and are subject to purchase and sale. Become. Further, when the input device is used as a user seal, it may be possible to purchase a product or borrow money using the input device.

  Then, in the service using the touch tool technology, if the authenticity of the input device cannot be ensured, the reliability of the service may be lost, and the service may not be realized. For example, it is possible to increase the number of stamps even though the product or service has not been purchased by disguising the positional relationship of the contact portion by hand and touching the multi-touch pad.

  The present invention has been proposed in order to solve the above-described problems of the prior art.

(First embodiment)
(Constitution)
An embodiment of an information processing system according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the information processing system 1 includes an input device 2 and an electronic device 3. An interface with the input device 2 included in the electronic apparatus 3 is a multi-touch pad 31. The electronic device 3 has a multi-touch pad 31 that can detect multiple points, such as a capacitance type or a resistance pressure-sensitive type. Hereinafter, the term “touch” refers to pressing according to the type of the multi-touch pad 31, pressing in the case of the resistance pressure type, and contact or proximity in the case of the capacitance type.

  When the electronic device 3 touches the multi-touch pad 31, the electronic device 3 determines whether the object is authentic. That is, the electronic device 3 determines whether the object touched on the multi-touch pad 31 is the input device 2 of the information processing system 1. As an authentic determination material, the input device 2 interferes with the instrument of the electronic device 3. When the electronic device 3 receives appropriate interference with the instrument, the electronic device 3 determines that the touched object is the input device 2 of the information processing system 1 and executes unique information processing for each touched input device 2.

  As shown in FIG. 2, the input device 2 has a block shape such as a rectangular parallelepiped as a whole, and the detailed shape varies depending on each individual. A plurality of contact portions 22 project from one surface of the block main body 21, and the plurality of contact portions 22 are changed in number, arrangement position, etc. by the input device 2 as shown in FIGS. 2 (a) and 2 (b). The positional relationship is different individually. The input device 2 gives a unique multi-point touch position to the multi-touch pad 31 through a plurality of contact portions 22. The electronic device 3 identifies the input device 2 from the positional relationship between the multiple touch positions, and executes information processing according to the input device 2.

  In the case where the multi-touch pad 31 included in the electronic device 3 is a capacitance type, the surface of the input device 2 may be formed of a conductive material. The conductive material is, for example, a conductive plastic such as metal or polyacetylene, a plastic mixed with metal fibers, or the like.

  Further, as shown in FIGS. 2C and 2D, a magnetic body 23 is embedded in the input device 2. The magnetic body 23 is a member that interferes with the magnetic sensor, such as a permanent magnet or a metal such as a ferrite core or iron oxide. When the input device 2 approaches the electronic device 3, the magnetic body 23 interferes with a magnetic sensor that is one of the instruments of the electronic device 3. In response to this interference, the electronic device 3 determines the authenticity of the object. The embedded position, orientation, and magnetic force of the magnetic body 23 may be common to each input device 2. However, the magnetic force of the magnetic body 23 is at least larger than the magnetic force of the human body. This is because at least the object touching the electronic device 3 can be identified as not being a human body.

  Next, the electronic device 3 shown in FIG. 3 is a so-called computer, stores an information processing program, executes the information processing program as appropriate, outputs an execution result, and controls peripheral devices according to the execution result. To do. In this information processing program, authenticity determination of an object, identification of the input device 2, and information processing code associated with the identified input device 2 are described.

  In addition to the multi-touch pad 31, the electronic device 3 includes at least a display 32, a magnetic sensor 33, a controller 34, and a storage 35. For example, the electronic device 3 is a smartphone, a tablet terminal, a PDA, a notebook PC, or the like. When the electronic device 3 is a smartphone, it has a touch panel in which the multi-touch pad 31 and the display 32 are overlapped, a transmission / reception unit 36a that transmits and receives call data and communication data, a speaker 36b that outputs a call sound, and a utterance sound. A sound microphone 36c, a rotation detection sensor 36d for the electronic device 3, and an acceleration sensor 36e are provided.

  The controller 34 is mainly composed of a CPU, appropriately executes an information processing program stored in the storage 35, and controls peripheral devices such as the display 32 and the magnetic sensor 33 according to the execution result. The storage 35 is a nonvolatile memory. FIG. 4 shows a functional configuration of the controller 34 realized by executing the information processing program by the controller 34. As shown in FIG. 4, the controller 34 includes a magnetic analysis unit 341, a touch data analysis unit 342, an information processing unit 343, and a display control unit 344.

  The magnetic analysis unit 341 is a determination unit that determines whether an object that has touched the multi-touch pad 31 for a predetermined time T is authentic. The magnetic analysis unit 341 receives an input of a magnetic force signal such as a numerical value indicating the magnitude of the magnetic force from the magnetic sensor 33 and analyzes whether a magnetic force change derived from the magnetic body 23 included in the input device 2 has occurred. As shown in FIG. 5, the magnetic analysis unit 341 stores in advance a magnetic force temporal change threshold Th. Then, the magnetic force change Var1 detected before and after the proximity of the object to the electronic device 3 is compared with the threshold Th. If the detected magnetic force change Var <b> 1 exceeds the threshold Th, the object touching the multi-touch pad 31 can be determined as the input device 2 of the information processing system 1.

  The touch data analysis unit 342 receives a touch position signal indicating a touch position from the multi-touch pad 31 and analyzes the positional relationship between the multi-point touch positions. The touch position signal is data such as coordinates indicating the touch position on the multi-touch pad 31. The multi-touch pad 31 corresponds to multi-point detection, and sequentially inputs the touch position signal of each touch position to the touch data analysis unit 342.

  For example, as shown in FIG. 6, a total of three contact portions 22 are projected from the input device 2. As shown in FIGS. 6A and 6B, when the contact portion 22 connects the three contact portions 22 with a single bend line L, the angles θ 1 and θ 2 of the bend lines L are determined by the input device 2. They are arranged differently. At this time, the positional relationship between the multi-point touch positions can be the bending angle θ of the bending line L. The touch data analysis unit 342 calculates the bending angle θ from the touch positions of the three contact portions 22. That is, to identify the input device 2 can be paraphrased as detecting the positional relationship of the contact portion 22.

  The information processing unit 343 performs information processing according to the input device 2, in other words, information processing according to the positional relationship between the multi-point touch positions. The execution of the information processing is premised on that the magnetic analysis unit 341 determines that the information is authentic. The storage 35 stores a processing content database 351 that shows information processing contents. The information processing unit 343 performs information processing according to the processing content indicated in the processing content database 351. This processing content database 351 is stored in the storage as part of the information processing program installation.

  FIG. 7 is a schematic diagram showing the processing content database 351. The processing content database 351 is associated with positional relationship information 352 indicating the positional relationship of multi-point touch positions and processing content information 353 indicating the content of information processing. The information processing unit 343 searches the positional relationship information 352 that matches the positional relationship of the multi-point touch positions analyzed by the touch data analysis unit 342, and follows the processing content information 353 associated with the corresponding positional relationship information 352. Execute the process. The processing content database 351 also stores processing content information 353 that sets the processing content as error processing when there is no matching positional relationship information 352.

  The display control unit 344 generates a display screen and causes the display 32 to display the display screen. The display screen can be classified into a stamping screen that receives a touch of the input device 2, an error screen when it is determined that the touched object is not authentic, and a result notification screen that notifies a result of information processing by the information processing unit 343.

(Function)
The operation of the information processing system 1 will be described taking application to a stamp service as an example. The stamp service is a system in which a customer is given a stamp for payment of goods and services at a store, and benefits such as discounts on goods and services are provided in exchange for a certain number of stamps. Generally, there is a stamp for each store.

  As shown in FIG. 8, each store has an input device 2 for increasing the stamp of its own store and an input device 2 for erasing all the stamps of its own store. The input device 2 for erasing all the stamps of the own store is used when a certain number of stamps of the own store are accumulated and the number of stamps is reset due to circumstances such as exchange for benefits. Therefore, the input device 2 has a plurality of contact portions 22 with a unique arrangement relationship according to a difference in function between increasing the store and the stamp or deleting all the stamps.

  A customer who receives a product or service owns the electronic device 3 in which an information processing program is installed. As shown in FIG. 7, the processing content database 351 of the electronic device 3 stores positional relationship information 352 that matches the contact portion 22 of the input device 2 owned by each store, and further processes the positional relationship information 352. Content information 353 is associated. In each processing content information 353, the store-specific stamp variable 353a indicating the number of stamps of the store, the change value 353b that increments the value indicated by the store-specific stamp variable 353a, or the value indicated by the store-specific stamp variable 353a is set to zero. A change value 353b is included.

  FIG. 9 is a flowchart showing the operation of the information processing system 1. When the customer pays for goods or services at a stamp service participating store and then receives the stamp service, the customer presses an activation icon displayed on the display of the electronic device 3 to activate the information processing program (step S01). . The information processing program is executed by pressing this activation icon. In the execution of the information processing program, the magnetic analysis unit 341 first starts monitoring the magnetic sensor 33 (step S02), and the display control unit 344 displays the stamping screen on the display 32 (step S03).

  If the predetermined time T has not elapsed since the stamping screen is displayed (No at Step S04), the magnetic analysis unit 341 continues to monitor the change in the magnetic force signal output from the magnetic sensor 33. The start of the fixed time T is not particularly limited as long as it is before the stamping screen is displayed. For example, the monitoring of the magnetic sensor 33 may be started. During the monitoring, the magnetic analysis unit 341 sequentially calculates the magnetic force change Var1 from the magnetic signals at two points at different times (Step S05), and compares the magnetic force change Var1 with the threshold Th (Step S06).

  If the magnetic force change Var1 does not exceed the threshold value Th (step S06, No) and the fixed time T has elapsed (step S04, Yes), the display control unit 344 displays an error screen on the display 32 (step S07). ). If the magnetic force change Var1 exceeds the threshold Th during the certain time T (step S06, Yes), the process proceeds to the process of the information processing unit 343, or the process of the information processing unit 343 is confirmed in parallel. That is, in this case, the determination that the magnetic analysis unit 341 is authentic can be rephrased as a determination of the magnitude of the magnetic force change Var1 with respect to the threshold Th.

  Here, when the staff of the store touches the multi-touch pad of the electronic device 3 owned by the customer for a certain time T, the magnet of the input device 2 is displayed as shown in FIG. The magnetic change Var1 analyzed by the magnetic analysis unit 341 by the body 23 exceeds the threshold Th. On the other hand, as shown in FIG. 10, even if the multi-touch pad 31 is touched by simulating the positional relationship of the contact portion 22 of the input device 2 as shown in FIG. Magnetic force change detected when approaching the electronic device 3 does not appear. Therefore, even if the input device 2 of the information processing system 1 is imitated by hand, an error screen is displayed on the display 32. That is, the number of stamps cannot be increased by disguising the input device 2 by hand.

  After the analysis by the magnetic analysis unit 341 or in parallel with the analysis, the touch data analysis unit 342 receives a touch position signal from the multi-touch pad 31 until a predetermined time T elapses after the stamping screen is displayed. . When the touch position signal is input (step S08), the touch data analysis unit 342 analyzes the positional relationship of the contact portion 22 from the multipoint touch positions indicated by the touch position signal (step S09). For example, the bending angle θ of the bending line L connecting the three contact portions 22 is calculated by coordinate calculation.

  When it is determined by the magnetic analysis unit 341 that the magnetic force change Var1 has exceeded the threshold Th (step S06, Yes), the information processing unit 343 matches the positional relationship of the multipoint touch positions analyzed by the touch data analysis unit 342. The positional relationship information 352 is searched from the processing content database 351 (step S10), and if the corresponding positional relationship information 352 exists (step S11, Yes), the processing is executed according to the processing content information 353 associated with the positional relationship information 352. (Step S12). On the other hand, if there is no corresponding positional relationship information 352 (step S11, No), the display control unit 344 displays an error screen (step S07).

  FIG. 12 is a diagram illustrating the value of the store-specific stamp variable 353 a that is updated and stored in the storage 35 as a result of the processing by the information processing unit 343. For example, when the input device 2 for increasing the stamps possessed by XX stores is touched to the electronic device 3, as shown in FIG. The value of the variable 353a is incremented by 1. Further, as shown in FIG. 12B, when the input device 2 for erasing all stamps of the XX store is touched to the electronic device 3, the information processing unit The value of the variable 353a is set to zero.

  Further, when the input device 2 for increasing the stamp of the XX store is touched to the electronic device 3, as shown in FIG. 12C, the information processing unit 343 displays the stamp for each store of the XX store. The value of the variable 353a is incremented by 1. Also, as shown in FIG. 12D, when the input device 2 for erasing all stamps of the XX store is touched to the electronic device 3, the information processing unit 343 displays the XX store by store. The value of the stamp variable 353a is set to zero.

  Then, when the processing by the information processing unit 343 is completed, the display control unit 344 displays a result notification screen (step S13). For example, when the number of stamps increases, the display 31 displays an effect in which the stamp is stamped on the stamp card. When the number of stamps reaches a certain number, it is possible to display the service contents that can be received in exchange for the stamp, along with the effect that the ball is broken. In addition, when the number of stamps is completely deleted for exchange with the service, an effect such as the appearance of a new stamp card can be displayed.

(Modification)
The information processing system 1 described above executes information processing in accordance with the input device 2, but is applicable not only to the stamp service as long as the authenticity of the input device 2 is required. For example, when the electronic device 3 is touched with the input device 2, data such as electronic money or a character may be purchased. Alternatively, a card of a battle type card game may be used as the input device 2 to ensure the fairness of the battle. Alternatively, the input device 2 may be used as a user seal for personal authentication.

  That is, processing content information 353 containing the type and amount of electronic money may be stored in the processing content database 351 according to the positional relationship of the contact portion 22 of the input device 2, or the contact portion of the input device 2 may be stored. Processing content information 353 containing the type of character according to the positional relationship of 22 may be stored in the processing content database 351. Further, only when it is determined that the input device 2 is authentic, the electronic document may be stamped. Further, only when it is determined that the input device 2 is authentic, the positional relationship of the contact portion 22 of the input device 2 is transmitted to the server, and personal authentication such as login is performed based on the positional relationship of the contact portion 22. Good.

  Further, the contact portion 22 may be capable of advancing and retracting with respect to the block main body 21 according to switching of the switch. There are two types of combinations of contact portions 22 that protrude from the block main body 21 in accordance with switching of the switches. Thereby, the input device 2 for increasing the number of stamps and the input device 2 for setting the stamp to zero can be covered by a single individual.

  Further, although the magnetic body 23 is embedded in the input device 2, the magnetic body 23 may interfere with the magnetic sensor 33 of the electronic apparatus 3 at the same time as the touch of the input device 2 or without any time difference. 21 and the magnetic body 23 can also be separated, and the input device 2 and the magnetic body 23 are not necessarily integrated. For example, the magnetic body 23 can be loaded into a glove, a ring, a work table or the like worn by a legitimate person. This is because if the authenticity of the person who handles the input device 2 can be determined, the input device 2 can be regarded as authentic.

  Furthermore, in the information processing system 1, the magnetic analysis unit 341 analyzes the magnetic force change in order to eliminate the influence of the magnetic environment around the electronic device 3. Therefore, when the magnetic body 23 having a magnetic force that can ignore the magnetic environment around the electronic device 3 is embedded in the input device 2, the magnetic analysis unit 341 stores a magnetic force threshold value in advance and stores the magnetic force signal. You may compare with the value which shows.

  In addition, the determination of authenticity may be performed with increased strictness according to the required degree of confirmation. As shown in FIG. 13, the magnetic sensor 33 of the electronic apparatus 3 includes X-axis, Y-axis, and Z-axis magnetic sensors 33a, 33b, and 33c that are orthogonal to each other. This magnetic sensor 33 has a multiplexer 33d, amplifies the signal by an amplifier 33e, digitally converts it by an A / D converter 33f, and then outputs it from the serial data interface 33g to the controller 34.

  The electronic device 3 incorporating the magnetic sensor 33 of the three-axis electronic compass can detect the magnitude of the magnetic force and the magnetic force change separately for each of the three axes. Therefore, the embedding position, orientation, and magnetic force of the magnetic body 23 with respect to the input device 2 are defined to be constant so that the magnetic force changes of the X axis, the Y axis, and the Z axis are different. That is, the direction and size of the magnetic field lines are defined.

  On the other hand, as shown in FIG. 14, the magnetic analysis unit 341 previously stores threshold values ThX, ThY, and ThZ for the X axis, the Y axis, and the Z axis. Further, as shown in FIG. 15, the magnetic analysis unit 341 stores a condition for determining whether the change in the magnetic force of any axis exceeds the threshold value, and when the change in the magnetic force of any axis falls below the threshold value. .

  The magnetic analysis unit 341 compares the magnetic force variations VarX, VarY, and VarZ of the X axis, the Y axis, and the Z axis with the threshold values ThX, ThY, and ThZ of each axis, and determines whether the condition is satisfied. As a result, if the condition is satisfied, the magnetic analysis unit 341 determines that the object touching the electronic device 3 is the input device 2 of the information processing system 1.

  As illustrated in FIG. 16, the magnetic analysis unit 341 stores the upper limit threshold UpL and the lower limit threshold LoL, and the magnetic force or change in magnetic force derived from the magnetic body 23 of the input device 2 does not fall between the upper limit threshold UpL and the lower limit threshold LoL. In some cases, the input device 2 can be made unauthentic.

  According to these authenticity determination methods, in addition to the camouflaging of the input device 2 by hand, even if the magnetic body 23 is simply brought close, or even if the user makes an improper input device 2, the accuracy of detecting the camouflaging of the input device 2 Can be increased.

  In this embodiment, the bending angle θ of one bending line L passing through the three contact portions 22 is analyzed as the positional relationship. However, the input device 2 is identified, that is, the positional relationship of the contact portion 22 is analyzed. Needless to say, the method is not limited to this method. For example, as shown in FIG. 17, the surface on which the contact portion 22 of the input device 2 protrudes is divided into a plurality of regions, the presence or absence of the contact portion 22 is detected for each region, and the region with or without the contact portion 22 is present. You may make it recognize positional relationship with the combination of an area | region.

  Depending on the number of matrices in the divided area, the recognized positional relationship may change depending on the orientation of the input device 2. In this case, a message that prompts the user to make the direction of the input device 2 appropriate may be displayed. Alternatively, the contact portions 22 are always protruded at the three corners of the matrix of the region, the contact portions 22 at the three corners are used for determining the orientation of the input device 2, and the other contact portions 22 are touched at multiple points. You may make it utilize as a positional relationship of a position.

  When the bending angle θ of one bending line L passing through the three contact points 22 is analyzed as a positional relationship, three types of bending angles θ are generated depending on how the three contact points 22 are connected. Each input device 2 may have three kinds of bending angles θ, but the bending angle θ can be determined as one as follows.

  That is, three contact portions 22 are separately provided at three corners of the surface on which the contact portion 22 is projected. The direction of the input device 2 is determined by the three contact portions 22 provided separately. Then, one kind of bending angle θ is derived corresponding to the direction of the input device. For example, the vertical direction of the input device 2 is detected. Then, a bending line L is drawn so as to be bent at the contact portion 22 located in the middle in the vertical direction of the input device 2. When there is a contact portion 22 having the same height in the vertical direction, a bending line L is drawn so as to be bent at the contact portion 22 located on the left side.

(effect)
As described above, in the information processing system 1, the input device 2 includes the plurality of contact portions 22 and the magnetic body 23. The plurality of contact portions 22 are arranged on one surface of the block main body 21 held by the user so that the multi-touch pad 31 of the electronic device 3 can be detected. The magnetic body 23 interferes with the magnetic sensor 33 of the electronic device 3. On the other hand, the electronic device 3 includes a magnetic analysis unit 341, and based on the magnetic sensor 33, the touch on the multi-touch pad 31 of the input device 2 having the magnetic body 23 is determined. That is, it is determined whether the object touched on the multi-touch pad 31 is the input device 2 of the information processing system 1. When the magnetic analysis unit 341 determines that the input device 2 is touched, the touch data analysis unit 342 analyzes the positional relationship of the contact portion 22 detected by the multi-touch pad 31, and the information processing unit 343 detects the touch data. The processing according to the positional relationship of the contact portion 22 analyzed by the analysis unit 342 is executed.

  As processing executed by the information processing unit 343, for example, a processing content database 351 that associates the positional relationship of the contact portion 22 with processing content is provided, and processing is executed according to the processing content information 353 of the processing content database 351. For example, using the stamp service as an application example, the processing content database 351 is referred to, and the number of store stamps corresponding to the positional relationship of the contact portion 22 is increased and stored.

  As a result, even if the input device 2 is disguised with a hand or other object and the multi-touch pad 31 is touched, the probability that the disguise of the impersonation will be detected on the electronic device 3 side increases, and fraud is not allowed. The reliability of the system 1 can be improved.

(Second Embodiment)
FIG. 18 is a configuration diagram of the controller 34 included in the electronic apparatus 3 according to the second embodiment. As shown in FIG. 18, the magnetic signal output from the magnetic sensor 33 is input to the information processing unit 343 in addition to the magnetic analysis unit 341 that determines the authenticity of the touched object. The information processing unit 343 uses the information of the magnetic signal in addition to the positional relationship of the multiple touch positions to search for the processing content information 353.

  That is, as shown in FIG. 19, processing content information 353 is associated with the processing content database 351 in accordance with the combination of the positional relationship information 352 and the magnetic force information 354. The magnetic force information 354 is a range of the magnetic force with respect to a single axis of the X axis, the Y axis, or the Z axis, or a range of the magnetic force for each of the X axis, the Y axis, and the Z axis, or a magnetic force with respect to the composition of the X axis, the Y axis, and the Z axis. Indicates the range.

  The information processing unit 343 searches for a combination of the positional relationship information 352 and the magnetic force information 354 that match the positional relationship of the multi-point touch positions and the magnetic signal information, and processes associated with the combination. Processing according to the content information 353 is executed.

  When the input to the electronic device 3 is a combination of the positional relationship between multiple touch positions and the information of the magnetic force signal, the input pattern is dramatically increased. By associating the processing content information 353 only with a part of the enormous input pattern, it is possible to further reduce the spoofing success rate of the input device 2. Or more various processing content information 353 can be linked | related, and the function of the information processing system 1 improves.

  The above embodiments are not intended to limit the scope of the present invention. Various omissions, replacements, and modifications may be made without departing from the spirit of the invention, and the present invention is not limited to this embodiment, and can be implemented in various other forms. And this embodiment and its deformation | transformation are included in the range and the summary of invention, and are included in the invention described in the claim, and its equivalent range.

  For example, the processing content database 351 may be stored not in the storage 35 of the electronic device 3 but in a server on the network. When storing in the server, processing may be performed on the server side in accordance with the processing content information 353 and the processing result may be transmitted to the electronic device 3 as the client, or the processing content information 353 may be transmitted to the electronic device 3 and the electronic device The third information processing unit 343 may perform processing. When the server is used, the electronic device 3 includes a transmission / reception unit 36a that can be connected to a network.
