Description

  The present invention relates to an information processing apparatus that performs connection authentication for data communication and a control method thereof.

  In recent years, it is often the case that data is stored in a small portable terminal and carried and exchanged with another portable terminal. In particular, mobile phones, digital cameras, and the like store a large amount of content that is frequently exchanged, such as image data captured by the terminal and address information.

  In order to transfer data between information devices, a method of data communication by connecting information devices with a USB or the like, or a cellular phone having an infrared communication function may exchange data using infrared communication. it can.

  However, in the method of connecting data devices to each other and performing data communication with each other, it is necessary to enter a password set for each device before data transfer, or to enter a one-time password or authentication code for communication connection. Work for connection authentication such as work to do was necessary.

  On the other hand, in communication between mobile phones using infrared communication, it is necessary to place the mobile phone on the data receiving side in a communication standby state and the side on which data is sent into a transmission state. In order to exchange data with each other, it was necessary to once terminate data communication and switch between a reception state and a transmission state again. In addition, since a terminal that performs data communication cannot be clearly specified, communication with the intended counterpart terminal may not be established.

In order to solve these problems, Patent Documents 1 and 2 propose a method including a mechanism for automatically recognizing a connection destination in a device to be connected in order to simplify the connection authentication work.

Also in Patent Document 2 described above, connection authentication for communication is simplified by reading electronic information written in a non-contact IC card or a non-contact IC tag in a non-contact manner by an RFID reader / writer. However, it is necessary to write electronic information in an information device connected in advance.

  As described above, in Patent Document 1 and Patent Document 2, in order to simplify the connection authentication work, it is necessary to prepare a mechanism for automatically recognizing a connection destination in a device to be connected. This is effective when data communication is performed between the two. However, there is a problem that a setting for simplifying the connection authentication work is required even when the connection is desired only once.

  In view of the above-described conventional problems, the object of the present invention is to clearly specify an information device that performs data communication while eliminating the need for setting for connection preparation, and to perform connection authentication for data communication between devices. A method is provided that simplifies and enables connection between intended information devices.

  In order to achieve the above object, a content display device according to an aspect of the present invention has the following arrangement. That is, a communication unit that transmits / receives data to / from another device, an input unit that inputs a first gesture, and an input reception unit that receives the second gesture input to the other device by the communication unit; Comparison means for comparing the first gesture input by the input means with the second gesture received by the input reception means, and authentication for authenticating the connection of the communication means based on the comparison result by the comparison means Means.

  Moreover, the control method of the content display apparatus by one aspect | mode of this invention for achieving said objective is provided with the following structures. That is, a communication step in which the communication unit performs data transmission / reception with another device, an input step in which the input unit inputs the first gesture, and a second gesture input to the other device is received by the communication unit.

  According to the present invention, it is possible to realize a reliable and simple information processing apparatus that can clearly specify an information apparatus that performs data communication and can simplify connection authentication between information apparatuses.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[First Embodiment]
Hereinafter, an information processing apparatus according to an embodiment of the present invention will be described with reference to the drawings. Hereinafter, the gesture input information is the trajectory information input to the coordinate input surface by handwriting, a stylus pen or the like according to the input gesture type in each embodiment, or the vibration detected and input by a vibration detection means such as an acceleration sensor. Indicates information.

  In the following description and drawings, the gesture input receiving means receives the above-described trajectory information and vibration information. In the following description and drawings, the gesture input receiving means receives and receives the trajectory information and vibration information described above. In the following description and drawings, the gesture comparison unit compares the above-described trajectory information and vibration information.

  FIG. 1 is a block diagram showing a configuration example of an information processing apparatus according to the present invention. The information processing apparatus 101 includes a communication unit 102, a gesture input receiving unit 103, a gesture input receiving unit 105, a gesture comparison unit 107, and a connection authentication unit 108. The communication unit 102 is a data communication unit that transmits and receives data to and from the external information processing apparatus 109. 103 gesture input reception means receives a user's gesture input input from the input device 110 as a gesture input 104 (first gesture). The gesture input receiving unit 105 receives a user gesture input from the outside to the information processing apparatus 109 as a gesture input 106 (second gesture) via the communication unit 102. Gesture comparison means The gesture comparison means 107 compares the gesture input 104 and the gesture input 106. The connection authentication unit 108 performs communication connection authentication for the external information processing device 109 based on the comparison result by the gesture comparison unit gesture comparison unit 107.

  In the present embodiment, by providing the header of gesture information with data indicating authentication data, it is identified as gesture information, and communication by the communication unit 102 is performed even for data before authentication. However, other methods may be used as long as gesture information can be communicated before authentication.

  FIG. 2 is a block diagram illustrating an example of a hardware configuration of the information processing apparatus according to the present invention.

  Reference numeral 202 denotes a CPU, which performs calculations and logic determinations for various processes, and controls each component connected to the bus 201. The apparatus includes a memory including a program memory and a data memory. The program memory stores a program for control by the CPU including a processing procedure described later with reference to the flowchart. The memory may be the ROM 203 or the RAM 204 into which a program is loaded from an external storage device. Reference numeral 205 denotes a storage device such as a nonvolatile memory or a hard disk for storing data and programs. Reference numeral 206 denotes an input device for inputting information from the user. Examples of this device include a mouse, a touch panel, and a keyboard. In the case of the present invention, an input device using a digitizer for inputting a handwritten locus or an acceleration sensor for inputting vibration information also corresponds to the input device. An output device 208 outputs the analyzed data output information, and is a display device such as a CRT or a liquid crystal display. Reference numeral 207 denotes a network I / F, which exchanges with other storage media and devices connected via the network. In the present invention, particularly, an I / F for wireless communication is included, and communication can be performed with an external device according to a standard such as IEEE 802.1X.

  In the present embodiment, the gesture input determination criterion for connection authentication is the same between the gesture input data, and the two information processing devices can simultaneously input by hand using two fingers for connection. An example is shown in which two devices can be authenticated at the same time. The gesture input data here is trajectory data, and the gesture input information 104 and the gesture input information 106 in FIG. 1 are trajectory information (first trajectory, second trajectory). In the following description, the identity is not completely the same, but a predetermined standard may be provided, and it may be determined that there is identity when it is considered that there is identity. Also, the term “simultaneous” may be regarded as simultaneous if a predetermined time difference is given with a predetermined time width.

  FIG. 3 is a flowchart showing an example of the overall processing flow for connection authentication of the information processing apparatus according to the first embodiment of the present invention. In the figure, S301 to S316 represent each step.

  In the present invention, the apparatus switches processing according to an event. In S301, an event is acquired in the event acquisition process. The type of event acquired in S302 is determined, and the process is switched. If it is determined in S302 that the event type is data communication start, the flow of processing proceeds to S305. If the determination result in S302 is other processing, other processing is performed in S304, and the process returns to the event acquisition processing in S301. If the determination result in S302 is the end of the process, the entire process ends.

  If the flow of processing proceeds from S302 to S305, communication is started in S305. Here, the communication link is established by searching for another information processing apparatus that can communicate with the apparatus. At this time, when a plurality of other information processing devices capable of communication are found, first, a device in a state where a communication start trigger is transmitted may be preferentially selected as a communication partner. Thereafter, the gesture input receiving unit 103 performs a gesture input initialization process in S306, a gesture input information reception process in S307, and a gesture input information transmission process in S308. On the other hand, the communication unit 102 and the gesture input receiving unit 105 perform communication data initialization processing in S309 and gesture input information reception processing in S310. In this embodiment, an example in which each process is performed in parallel is shown, but each process may be performed in the order of S306, S307, S308, S309, and S310.

  In step S306, the gesture input receiving unit 103 performs a gesture input initialization process. Here, for example, when the gesture input is handwritten input, the apparatus is in a state where handwriting input is possible. Subsequently, in the gesture input information reception process of S307, a gesture input from the user is received. An example of the gesture input information accepted here is as shown in FIG. 5, for example. FIG. 5 will be described later. In step S308, the communication unit 102 is requested to transmit the gesture input information to the communication destination.

  On the other hand, the communication unit 102 performs communication data reception initialization processing in S309. Then, in a state in which data can be received, the gesture input receiving unit 105 receives the user's gesture input information to the other information processing apparatus 109 from the outside in the gesture input information receiving process in S310.

  When the gesture input information receiving process (S307) and the gesture input information receiving process (S310) are completed, it is determined in step S311 whether or not the gesture input information can be compared as a result of each process.

  If it is possible to compare the gesture input information in the determination in S311, the process flow proceeds to the gesture input determination process in S312. If it is difficult to compare the gesture input information and it is necessary to acquire the gesture input information again, the process returns to S306 and S309. Here, when it is difficult to compare the gesture input information, for example, when the distance between two pieces of input information is calculated by DP matching or the like, this distance exceeds a predetermined value. Further, there are cases where the gesture input in the own apparatus has failed, or when a gesture error has occurred during the reception of the gesture input data received from another information processing apparatus 109.

  In the gesture input determination process in S311, the two pieces of gesture input information acquired in the gesture input information reception process in S307 and the gesture input information reception process in S310 are compared, and the result is passed to the data communication connection authentication process in S312. . The S312 gesture input determination process will be described in detail with reference to FIG.

  In the data communication connection authentication process of S313, based on the result of the S312 gesture input determination process, a data communication authentication to another information processing apparatus 109 corresponding to the gesture input information received in the gesture input information reception process of S310 is issued. Decide whether you want to do it. The result of the data communication connection authentication process in S313 is determined in S314. If it is determined to notify communication authentication in S314, communication authentication is notified in the data communication processing of S315, and data communication is permitted to the other information processing apparatus 109 to perform actual data communication. When the data communication process ends in S315, the process flow proceeds to S316. On the other hand, if it is determined in step S314 that communication authentication is not notified, the process flow proceeds to step S316. Finally, communication is terminated in S316, the flow of processing returns to S301, and an event wait state is entered.

  FIG. 4 is a diagram illustrating an example of user input to the information processing apparatus according to the present embodiment.

  Reference numerals 401 and 402 described with reference to FIGS. 1 and 2 denote information processing apparatuses according to the present invention. Here, it is assumed that the information processing apparatuses 401 and 402 include areas such as 403 and 404 that can be input by handwriting. In this embodiment, a user arranges 401 and 402 information processing devices side by side, and inputs handwritten gesture input information having a handwriting locus such as 405 and 406 to each information processing device 401 and 402 using two fingers. . Here, in order to simplify the description in FIG. 4, handwritten trajectories such as 405 and 406 are displayed in an area where 403 and 404 handwritten input is possible. However, in an actual apparatus, the trajectory is not displayed. Any configuration may be used.

  In this embodiment, it is assumed that an actual handwriting input is performed after generating a trigger event for starting communication between both of the information processing apparatuses 401 and 402. A communication start trigger event may be set for each information processing apparatus. For example, a communication start button may be prepared, or a communication start gesture may be registered. Due to this trigger event of communication start, in the entire processing in each information processing apparatus, the determination in S302 proceeds to S305, and communication is started in S305.

  Thereafter, in each of the information processing apparatuses 401 and 402, the gesture input receiving unit 103 performs the processes of S306, S307, and S308, while the communication unit 102 and the gesture input receiving unit 105 perform the processes of S309 and S310. That is, processing for communication connection authentication is simultaneously performed in each of the information processing apparatuses 401 and 402. FIG. 5 is a diagram showing an example of gesture input information according to the present invention. The gesture input information received by the apparatus in this embodiment includes apparatus information 501, gesture type information 502, and gesture input data 503. In the present embodiment, the gesture input information is composed of three pieces of information, but an actual apparatus may be configured not to include either the apparatus information 501 or the gesture type information 502 or both. In this case, different information can be used as the information corresponding to the device information 501 and the gesture type information 502.

  Gesture input information input by the user as shown in FIG. 4 is created in the information processing apparatuses 401 and 402, respectively.

  FIG. 6 is a diagram showing an example of the gesture input determination process in S312 in the embodiment according to the present invention. In the figure, S601 to S610 represent each step.

  In S601, the result of the gesture input information reception process obtained in S307 is acquired. The information acquired here is referred to as gesture input information A for the following description.

  In step S602, the result of the gesture input information reception process obtained in step S310 is acquired. The information acquired here is referred to as gesture input information B for the following description.

  In step S603, a gesture input comparison determination criterion is acquired. Here, the gesture input comparison judgment criterion represents how the gesture input information A and the gesture input information B are compared. This reference may be set in advance for each apparatus, or may be set in the gesture input initialization process in S306. In this embodiment, it is assumed that the gesture input comparison determination criterion is set to “identity between gesture input data”.

  In step S604, the gesture type is acquired. Here, when the gesture input information A and the gesture input information B are configured as shown in FIG. 5, the gesture type may be acquired from each gesture input information, and may be used when they match. When the gesture input information does not include the gesture type, the gesture type may be set according to how and in which processing unit the device receives the gesture input from the user in the S307 gesture input information reception process. In the latter case, in this embodiment, handwritten gesture input is accepted from an area where handwriting input is possible, such as 403 and 404, so that the gesture type can be set as handwritten.

  Subsequently, using the gesture input information A and the gesture input information B as a result of the processing in S601 and S602, each gesture input data is acquired in S605. Subsequently, in the determination in S606, the process is divided according to the gesture input comparison determination criterion acquired in S603.

  If the gesture input comparison determination is the identity of the gesture input data, the process proceeds to the gesture input data identity determination process in S607 as a result of the determination in S606. Details of the gesture input data identity determination processing in S607 will be described later in detail with reference to FIG. If the gesture input comparison determination is the relevance between the gesture input data, the determination in S606 proceeds to the S608 gesture input data relevance determination process. Details of the gesture input data relevance determination processing in S608 will be described later in detail with reference to the drawings. If the gesture input comparison determination is another criterion, the determination in S606 proceeds to S609 other gesture input data determination base processing. When each process ends, the determination result is output in S610, and the S312 gesture input determination process ends.

  FIG. 7 is a diagram showing an example of the data communication connection authentication process of S313 in the embodiment according to the present invention. In the figure, steps S701 to S703 represent each step. First, in step S701, the result of the gesture input determination process is acquired.

  The result acquired in S702 is determined. If the determination by the gesture input comparison is OK, the communication unit 102 is requested to issue a communication connection authentication in S703, and the data communication connection authentication process in S313 is terminated. In the case of NG, the process ends as it is.

  FIG. 8 is a diagram showing an example of the gesture input data identity determination process in S607 according to the first embodiment of the present invention. In the figure, steps S801 to S807 represent each step.

  First, in S801, the process is divided according to the gesture type acquired in S604. If the gesture type is handwritten, the flow of processing proceeds from the determination in S801 to the handwritten data identity determination processing in S802. If the gesture type is vibration, the flow of processing proceeds from the determination in S801 to the vibration data identity determination processing in S803. If the gesture type is other, the flow of processing proceeds from the determination in S801 to other identity determination processing in S804. In the present embodiment, since the gesture type is handwritten, the process proceeds to the handwritten data identity determination process in S802.

  In S802, in this embodiment, the identity is determined by determining the similarity between the gesture input data acquired from the gesture input information A and the gesture input information B. Here, general techniques such as handwriting recognition can be used. In this embodiment, since handwriting is simultaneously performed with two fingers, the similarity is considered to be very high. For example, even if another device that has established a communication link as being communicable in S305 and performs handwriting input in the same manner by imitating a handwritten gesture, the similarity is likely to be lower than in this embodiment.

  When the identity determination process ends, the identity of the gesture input data is determined in S805. If the identity of the data is determined as a result of the determination in S805, the identity determination of the gesture input data is OK in S806. If the identity of the data is not judged as a result of the judgment in S805, the identity judgment of the gesture input data is set to NG in S807. In determining the identity, the similarity of only the shapes of the gesture input data may be determined, or the time information may be further used to determine the identity based on the input data input at the same time. With the above processing, the gesture input data identity determination processing ends.

  In this embodiment, when handwritten with two fingers at the same time, the similarity becomes high, and the determination in S805 results in the recognition of the identity of the data. In S806, the determination of the identity of the gesture input data is OK. . The result of this identity determination process is output in S610 in FIG. 6, and is passed to S313 as the result of the gesture input determination process in S312 in FIG. 3. In the data communication process in S315, communication authentication is notified, and other devices The data communication is permitted to the actual data communication. In the present embodiment, communication authentication is performed in such a flow in the information processing apparatus 401, and communication authentication is notified to the information processing apparatus 402 that has performed handwriting input at the same time. Similarly, communication authentication is performed on the information processing apparatus 401 as a result of the same processing in the information processing apparatus 402.

  As described above, according to the present embodiment, handwriting input is performed on two devices simultaneously with two fingers, so that an information device for performing data communication can be clearly specified. Further, connection authentication between information devices can be simplified without setting connection preparation or the like.

  In addition, according to the present embodiment, each of the information processing apparatuses 401 and 402 can perform processing for communication connection authentication at the same time. Data communication authentication can be performed.

(Second Embodiment)
In the above-described embodiment, an example in which the gesture input comparison determination criterion for connection authentication is the same between the gesture input data has been shown. However, in this embodiment, the gesture input comparison determination criterion for connection authentication is An example of the relationship between gesture input data is shown. FIG. 9 is a diagram for explaining user input in the second embodiment of the present invention.

  Reference numerals 901 and 902 denote information processing apparatuses according to the present invention. Since the configuration of the information processing apparatus and the hardware configuration are the same as those described in the first embodiment, they are omitted here. Here, it is assumed that the information processing apparatuses 901 and 902 have the same size handwritten input areas as 903 and 904. In the present embodiment, the user places the information processing apparatuses 901 and 902 side by side and touches them, and inputs a handwriting input gesture that spans two apparatuses. Thereby, handwritten gesture input information having a handwriting locus such as 905 is input to the information processing device 903, and handwriting gesture input information having a handwriting locus such as 906 is input to the information processing device 904. . Here, in order to simplify the description in FIG. 9, handwritten trajectories such as 905 and 906 are displayed in the areas where 903 and 904 handwritten input is possible, but the actual apparatus does not display the trajectories. Any configuration may be used.

  Here, the two information processing devices are in contact with each other so that the upper part of each handwritten input area is aligned, and the handwriting gesture input of the two devices is as if it were input on one coordinate input surface. Become.

  Also in the present embodiment, as in the first embodiment described above, it is assumed that an actual handwriting input is performed after a trigger event for starting communication is generated in both the information processing apparatuses 901 and 902. A communication start trigger event may be set for each apparatus. For example, a communication start button may be prepared, or a communication start gesture may be registered. With this trigger event for starting communication, in the overall processing in each apparatus, the process proceeds to S305 in the determination of S302 in FIG. 3, and communication is started in S305. Thereafter, in each of the information processing apparatuses 901 and 902, the gesture input receiving unit 103 performs the processes of S306, S307, and S308, while the communication unit 102 and the gesture input receiving unit 105 perform the processes of S309 and S310. That is, processing for communication connection authentication is performed simultaneously in each of the information processing apparatuses 901 and 902.

  In the second embodiment, the flow of the entire process for connection authentication is the same as the entire process of FIG.

  The gesture input determination process in S312 described with reference to FIG. 6 is the same as that in the first embodiment, but in this example, the gesture input comparison determination criterion for connection authentication is “relationship between gesture input data”. Is set. Then, the determination in S606 proceeds to S608 gesture input data relevance determination processing.

  FIG. 10 is a diagram showing an example of the gesture input data relevance determination process according to the second embodiment of the present invention. In the figure, steps S1001 to S1010 represent each step.

  First, in S1001, a gesture type is acquired. If the gesture type is handwritten, the determination in S1001 proceeds to the handwritten data discontinuity acquisition processing in S1002. If the gesture type is other than that, the determination in S1001 proceeds to S1003, and other relevance determination processing is performed. In the present embodiment, since the gesture type is handwritten, handwritten data discontinuous point acquisition processing is performed in S1002. The discontinuous points to be acquired are points corresponding to 907 to 911 in FIG. 9 where the input by the handwriting input gesture touches each of the handwritten input possible areas 903 and 904. Here, in the information processing device 903, (X1, A1), (X1, B1), (X1, C1) are used as the coordinates of the discontinuous points 907 to 911 from the handwritten gesture input information having a handwritten locus such as 905. ), (X1, D1), (X1, E1). Then, the information processing apparatus 904 receives (0, A2), (0, B2), (0, C2), (0, A2) as coordinates of discontinuous points 907 to 911 from handwritten gesture input information having a handwriting locus such as 906. Assume that (0, D2) and (0, E2) are acquired. Here, in each of the handwritten input possible areas 903 and 904, the upper left coordinate is (X, Y) = (0, 0), and the lower right coordinate is (X, Y) = (X, Y) (handwritten input is possible). Area size). In the present embodiment, it is assumed that the time information when each coordinate is input is included in the handwritten gesture input information.

  Subsequently, a discontinuous point comparison process is performed in S1004. In the present embodiment, when the coordinates of the respective gesture input data are compared based on the coordinate input time information, (X1, A1) and (0, A2), (X1, B1) and (0, B2), The input time information of (X1, C1) and (0, C2), (X1, D1) and (0, D2), (X1, E1) and (0, E2) is almost the same. Therefore, since the coordinate changing with time is the Y coordinate, the change in the Y coordinate is compared. As a result of comparison, in this embodiment, A1 = A2, B1 = B2, C1 = C2, D1 = D2, and E1 = E2. Therefore, it can be determined that each handwritten input enable area 903 and 904 can be joined by two handwritten gesture inputs at the interface X = X in the handwritten input enable area 903 and the interface x = 0 in the handwritten input enable area 904.

  Based on this result, the determination in S1005 proceeds to S1006, and it is assumed that the two gesture input data are related. If connection cannot be established at the interface between the two gesture input data, the determination in S1005 proceeds to S1007, and it is assumed that the two gesture input data are not related.

  Subsequently, in S1008, the relevance of the gesture input data is determined based on the results of the processing so far. If there is a relevance of the gesture input data, the determination of the relevance of the gesture input data is OK in S1009. If there is no relevance of the gesture input data, the gesture input data relevance determination is set to NG in S1010. When each process ends, the determination result is output in S610, and the S312 gesture input determination process ends.

  In the present embodiment, the devices are installed next to each other, and handwriting input is performed across the two devices. Therefore, it is considered that the similarity of the coordinate points at the boundary is very high. Therefore, the determination in S1005 is data relevance, and the relevance determination of the gesture input data is OK in S1006. This result is passed to S313 as a result of the S312 gesture input determination process in S610 of FIG. 6, and in S315 data communication process, communication authentication is notified, and data communication is permitted to other devices and actual data communication is performed. As described above, in the present embodiment, communication authentication is performed in this manner in the information processing apparatus 901, and at the same time, communication authentication is notified to the information processing apparatus 902 that has performed handwritten input across the apparatuses. Similarly, as a result of the same processing in the information processing apparatus 902, communication authentication is performed for the 901 information processing apparatus.

  According to the present embodiment, since handwritten gesture input that spans two devices at the same time is performed, an information device that performs data communication can be clearly specified. Further, connection authentication between information devices can be simplified without setting connection preparation or the like.

  In addition, according to the present embodiment, since the processing for communication connection authentication can be simultaneously performed in each of the information processing devices 901 and 902, for the user, mutual information processing between the information processing devices 901 and 902 can be performed with a single operation. Data communication authentication can be performed.

  In this embodiment, the relevance is determined by comparing the coordinates of the discontinuous points with reference to the input time information. However, based on the coordinates of the input handwritten input data, an input function related to the time information is obtained. You may make it produce | generate and compare them. With such a configuration, it is possible to determine the relevance even when the coordinate systems of the devices are different.

(Third embodiment)
In each of the above-described embodiments, the handwriting gesture input of the two devices is input using the same coordinate interval, and each information processing device is in contact with the upper part of each handwritten input area. An example is shown. In the present embodiment, an example is shown in which two devices are in contact with each other while being vertically displaced. In the present embodiment, the gesture input comparison determination criterion for connection authentication is the relationship between the gesture input data.

  FIG. 11 is a diagram for explaining a user input in the third embodiment according to the present invention.

  Reference numerals 1101 and 1102 denote information processing apparatuses according to the present invention. Since the configuration and hardware configuration of the information processing apparatuses 1101 and 1102 are the same as those described in the first embodiment, they are omitted here. Here, it is assumed that the information processing apparatuses 1101 and 1102 have handwritten input areas of the same size, such as 1103 and 1104. In this embodiment, the user puts the information processing apparatuses 1101 and 1102 side by side and touches them, and inputs a handwriting input gesture that spans two apparatuses. As a result, handwritten gesture input information having a handwriting locus such as 1105 is input to the information processing apparatus 1103, and handwriting gesture input information having a handwriting locus such as 1106 is input to the information processing apparatus 1104. . Here, in order to simplify the description in FIG. 11, handwritten trajectories such as 1105 and 1106 are displayed in areas where 1103 and 1104 handwritten input is possible, but the actual apparatus does not display the trajectories. Any configuration may be used. It is assumed that the two information processing devices are in contact with each other in a state where each handwriting input area is shifted by Δy. In addition, the handwritten gesture input of the two devices is input as if it were one coordinate input surface.

  Also in the present embodiment, as in the first embodiment described above, actual handwriting input is performed after generating a trigger event for starting communication in both information processing apparatuses 1101 and 1102. A communication start trigger event may be set for each apparatus. For example, a communication start button may be prepared, or a communication start gesture may be registered. By this communication start trigger event, in the entire processing in each apparatus, the process proceeds to S305 in the determination of S302, and communication is started in S305.

  Thereafter, in each of the information processing apparatuses 1101 and 1102, the gesture input receiving unit 103 performs the processes of S306 and S307, while the communication unit 102 and the gesture input receiving unit 105 perform the processes of S308 and S309. That is, processing for communication connection authentication is performed simultaneously in each of the information processing apparatuses 1101 and 1102.

  In the present embodiment, the flow of the entire process for connection authentication is the same as the overall process of FIG. 3 described in the first embodiment, and details thereof are omitted. The same applies to the S312 gesture input determination process described with reference to FIG. However, in this embodiment, the gesture input comparison determination criterion for connection authentication is set as “relevance between gesture input data”. For this reason, the determination in S606 proceeds to S608 gesture input data relevance determination processing.

  FIG. 12 is a diagram showing an example of the gesture input data relevance determination process in the third embodiment according to the present invention. In the figure, S1001 to S1010 and S1201 to S1203 represent each step. In FIG. 12, steps from S1201 to S1203 are added compared to FIG. 10 in the second embodiment. Since the other processing flow from S1001 to S1010 is the same as that of FIG. 10 in the second embodiment, the description thereof is omitted here.

  In the present embodiment, the discontinuous points acquired in S1002 are points corresponding to 1107 to 1111 in FIG. 11 where the input by the handwriting input gesture touches each of the handwritten input possible areas 1103 and 1104. Here, in the information processing apparatus 1103, (X1, E1), (X1, F1), (X1, G1) are used as the coordinates of the discontinuous points 1107 to 1111 from handwritten gesture input information having a handwriting locus such as 1105. ), (X1, H1), (X1, I1) are acquired. Then, the information processing apparatus 1104 uses (0, E2), (0, F2), (0, G2), (0, E2) as coordinates of discontinuous points 1107 to 1111 from handwritten gesture input information having a handwriting locus such as 1106. Assume that (0, H2) and (0, I2) are acquired. Here, in each handwritten input enable area 903, 904, the upper left coordinate is (x, y) = (0, 0), and the lower right coordinate is (x, y) = (X, Y) (handwritten input is possible). Area size). In the present embodiment, it is assumed that the time information when each coordinate is input is included in the handwritten gesture input information.

  Subsequently, in S1201, discontinuous point partial comparison processing is performed. Here, as a preparation for the S1004 discontinuous point comparison process, some of the discontinuous points are compared. In the present embodiment, only the coordinates of the first two points of the gesture input data are compared as a part of the discontinuous points. In the present embodiment, the coordinates of each gesture input data are compared based on the coordinate input time information. Then, (X1, E1) and (0, E2), (X1, F1) and (0, F2), (X1, G1) and (0, G2), (X1, H1) and (0, H2), The input time information of (X1, I1) and (0, I2) is almost the same. Therefore, since the coordinate changing with time is the y coordinate, the change of the y coordinate is compared. When the first two points are compared, in the present embodiment, when E1 and E2 and F1 and F2 are compared, it can be seen that they do not match, and it is determined that correction is necessary. Here, in this embodiment, the judgment criteria that need to be corrected are determined to be inconsistent as a result of partial comparison. However, in the actual configuration, even if the necessity for correction is judged using another criterion. good.

  If there is a need for correction in S1202, the process proceeds to the gesture input data correction process in S1203. The gesture input data correction process in S1203 will be described in detail with reference to FIG. If there is no need for correction, the process proceeds to S1004 discontinuous point comparison process as it is, and the process proceeds in the same manner as in the second embodiment.

  FIG. 13 is a diagram showing an example of the gesture input correction process in the third embodiment according to the present invention. In the figure, S1301 to S1303 represent each step.

  First, in S1301, a coordinate axis whose value is changing is obtained from the handwritten data discontinuous point coordinates. In this embodiment, as described above, (X1, E1) and (0, E2), (X1, F1) and (0, F2), (X1, G1) and (0, G2), (X1, H1) ) And (0, H2), and (X1, I1) and (0, I2) have substantially the same input time information. Therefore, the coordinate changing with time is the y coordinate. Subsequently, in S1302, a deviation of the two handwritten data discontinuous points with respect to the y-axis is calculated. Each coordinate (X1, E1) and (0, E2), (X1, F1) and (0, F2), (X1, G1) and (0, G2), (X1, H1) and (0, H2), The change of the y coordinate of (X1, I1) and (0, I2) will be compared. Then, since E1 = E2 + Δy, F1 = F2 + Δy..., It can be calculated that there is a deviation of Δy in the grounding of each handwritten input possible region 903, 904. Here, in this embodiment, when calculating the deviation, the same deviation can be calculated in the result of the comparison of each coordinate point. However, in the actual configuration, the deviation is calculated by calculating the average of the deviations of each coordinate point. It is also good. Alternatively, each handwritten data discontinuity may be expressed as a function of time and y-coordinate, and calculation may be performed such that the phases of each function are matched.

  In S1303, the deviation Δy calculated in S1302 is set to the coordinates of the discontinuous points 1107 to 1111 (0, E2), (0, F2), (0, G2), (0, H2), (0, I2). ) Is corrected in addition to the y coordinate. That is, the gesture input data used in S1004 discontinuous point comparison processing includes the coordinates of discontinuous points 1107 to 1111, (X1, E1), (X1, F1), (X1, G1), (X1, H1), (X1, I1) and coordinates corrected as the coordinates of the discontinuous points 1107 to 1111, (0, E2 + Δy), (0, F2 + Δy), (0, G2 + Δy), (0, H2 + Δy), (0, I2 + Δy) It becomes.

  After completion of the S1203 gesture input correction process, the process proceeds to S1004 discontinuous point comparison process, and the process proceeds in the same manner as in the second embodiment. Also in this embodiment, the determination in S1005 is data relevance, and the relevance determination of the gesture input data is OK in S1006. This result is output in S610 in FIG. 6, and is passed to the data communication connection authentication process in S313 as a result of the S312 gesture input determination process in FIG. 3. In the data communication process in S315, the communication authentication is notified, and the other apparatus is notified. Allow data communication and perform actual data communication. As described above, in the present embodiment, communication authentication is performed in such a flow in the information processing apparatus 1101, and at the same time, communication authentication is notified to the information processing apparatus 1102 that has performed handwritten input across each apparatus. Similarly, communication authentication is performed on the information processing apparatus 1101 as a result of the same processing in the information processing apparatus 1102.

  As described above, according to the present embodiment, when performing handwriting gesture input that simultaneously spans two devices, even if the handwriting input area is shifted, correction is performed between information devices. Connection authentication can be performed accurately.

(Fourth embodiment)
In each of the above-described embodiments, an example in which the gesture type input by the user is handwritten is shown. However, in this embodiment, an example in which the gesture type input by the user is vibration is shown. Since the configuration of the information processing apparatus and the hardware configuration are the same as those described in the first embodiment, they are omitted here.

  FIG. 14 is a diagram for explaining a user input in the fourth embodiment according to the present invention. A user holds two information processing apparatuses 1401 and 1402 to be connected at once, and inputs a vibration gesture by shaking up and down. In this embodiment, the gesture input comparison criteria for connection authentication are the same between the gesture input data.

  Also in the present embodiment, as in the first embodiment described above, actual handwriting input is performed after generating a trigger event for starting communication in both information processing apparatuses 1101 and 1102. A communication start trigger event may be set for each apparatus. For example, a communication start button may be prepared, or a communication start gesture may be registered. With the trigger event for starting communication, in the overall processing in each apparatus, the determination in S302 of FIG. 3 proceeds to S305, and communication is started in S305.

  Thereafter, in each of the information processing apparatuses 1101 and 1102, the gesture input receiving unit 103 performs the processes of S306, S307, and S308, while the communication unit 102 and the gesture input receiving unit 105 perform the processes of S309 and S310. That is, processing for communication connection authentication is performed simultaneously in each of the information processing apparatuses 1101 and 1102.

  In the present embodiment, the overall process flow for connection authentication is the same as the overall process of FIG. 3 described in the first embodiment, and the details are omitted.

  Further, since the gesture input determination process (S312) in the present embodiment is the same as the gesture input determination process described with reference to FIG. 6 in the first embodiment, the details are omitted.

  In the present embodiment, “vibration” is acquired as the gesture type in S604 of FIG. Furthermore, in the determination in S606, the gesture input comparison determination criterion for connection authentication is set as “identity between gesture input data”, so the determination in S606 proceeds to the S607 gesture input data identity determination process.

  The gesture input data identity determination process of S607 in the present embodiment is the same as the gesture input data identity determination process described with reference to FIG.

  In the present embodiment, as a result of the determination in S801, the process proceeds to S803, and vibration information identity processing is performed. In this process, the identity of the gesture input data is determined. In this embodiment, since two information processing devices are stacked and shaken at the same time, the similarity of the vibration information is very high. Therefore, the determination is that the data is identical, and the gesture input data is the same. A result with the sex judgment OK is output. This result is passed to S313, and in S315 data communication processing, communication authentication is notified, data communication is permitted to other devices, and actual data communication is performed. In the present embodiment, communication authentication is performed in such a flow in the information processing apparatus 1401, and the communication authentication is notified to the information processing apparatus 1402 that has performed handwriting input at the same time. Similarly, as a result of the same processing in the information processing apparatus 1402, communication authentication is performed on the information processing apparatus 1401.

  As described above, according to the present embodiment, it is possible to authenticate connection between two information processing devices by simultaneously shaking the two information processing devices and applying vibration as a gesture input.

  In this embodiment, the vibration gesture is given by simultaneously shaking the two information processing devices. However, the same vibration information may be given to each other by hitting the two information processing devices.
