Description

  The present invention relates to an information processing apparatus that receives information from an electronic pen, a method for scoring a test answer written with the electronic pen, and the like.

  Conventionally, as an electronic pen that can transmit the described information to the outside, there is an electronic pen manufactured by Anoto (see Non-Patent Document 1). This electronic pen is an ordinary pen equipped with an ultra-small camera, an image recognition device, and Bluetooth (Bluetooth is a registered trademark of “Telephonon Acty Boraget L. Ericsson”) transceiver device. It can read and analyze written handwritten content, and can immediately send and receive it to information communication devices such as personal computers, mobile phones, and fax machines.

  Note that Bluetooth is a wireless communication standard, and the transmission distance is about 10 m when the transmission power is 1 mW, and is a wireless standard that is conscious of power saving and short distance. Moreover, by increasing the transmission power, the transmission distance can be extended up to 100 m at present.

There are also systems for sending test information and automatic scoring using a computer network.

  However, the conventional automatic scoring system such as a test calculates the score of the test from the received student responses and the stored test responses. In other words, the conventional system calculates the score based only on the result of the student's answer. Specifically, flexible scoring was not possible considering the time and behavior of students to answer.

  Therefore, the present invention provides a pen identifier that is information for identifying the electronic pen from the electronic pen, a pen information receiving unit that receives one or more pen information having coordinate information indicating the locus of the electronic pen, and one or more pen information. The description information acquisition unit that acquires description information that is information described with an electronic pen, the time acquisition unit that acquires the time when the pen information reception unit received the pen information, and the description information acquisition unit Information including a score calculation unit for calculating the score of the description information based on the written information and the time acquired by the time acquisition unit, and a score storage unit for storing the score calculated by the score calculation unit in association with the pen information It is a processing device, and with this information processing device, flexible scoring is possible in consideration of the time and behavior of student responses.

  According to the present invention, flexible scoring using the characteristics of the electronic pen is achieved by a scoring method that receives information from the electronic pen and calculates a score based on the received information and the time when the information is received. Is possible.

Embodiments of the present invention will be described below in detail with reference to the drawings. Note that in this embodiment, components using the same reference numerals and steps in the flowcharts perform the same function, and thus description of what has been described once may be omitted.
(Embodiment 1)

  FIG. 1 is a conceptual diagram of an information processing system in the present embodiment. The information processing system includes electronic pens 12 and information processing devices 13 that are media 11 and 2 or more. The medium 11 is a medium on which a special dot pattern is printed, and is made of paper, for example.

  FIG. 2 is a block diagram of the information processing system in the present embodiment. The electronic pen 12 includes a pen identifier storage unit 1201, a coordinate information acquisition unit 1202, a pen information configuration unit 1203, and a pen information transmission unit 1204.

  The information processing apparatus 13 includes a pen information receiving unit 1301, a written information acquisition unit 1302, a time acquisition unit 1303, a score calculation unit 1304, a score accumulation unit 1305, an input reception unit 1306, and a score output unit 1307.

  The pen identifier storage unit 1201 stores a pen identifier that is information for identifying an electronic pen. The data structure and content of the pen identifier are not limited. The pen identifier storage unit 1201 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium.

  The coordinate information acquisition unit 1202 acquires coordinate information that is information on relative coordinates in the medium 11. For example, the coordinate information acquisition unit 1202 acquires the coordinate information as follows. When the special dot pattern shown in FIG. 18 is printed on the medium 11, the coordinate information acquisition unit 1202 can be realized by a coordinate detection technique using a special dot pattern. Specifically, for example, the configuration is as shown in FIG. 18 includes a CCD camera 1801 and a processor 1802 that performs pattern recognition and analysis. The special dot pattern represents dots along a grid with a pitch of 0.3 mm, and coding is performed by distributing the arrangement of the dots by four patterns of Right / Left / Up / Down. Then, a special dot pattern is photographed at 60 frames / second from the CCD camera and input. Then, by analyzing the captured image information, it is possible to detect the movement of the CCD camera as the input device (that is, the change in the captured dot pattern). By detecting the movement of the CCD camera, relative coordinate information in the static object can be acquired. As another means of the coordinate information acquisition unit 1202, the following can be considered. A barcode indicating coordinate information is printed on the surface of the medium 11, and the coordinate information acquisition unit 1202 is realized by a barcode reader that reads the barcode and obtains the coordinate information.

  The pen information configuration unit 1203 configures pen information having the pen identifier in the pen identifier storage unit 1201 and the coordinate information acquired by the coordinate information acquisition unit 1202. The pen information is not limited to the pen identifier and the coordinate information. The pen information configuration unit 1203 can usually be realized by an MPU, a memory, or the like. The processing procedure for the pen information configuration unit 1203 to configure the pen information is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The pen information transmission unit 1204 transmits the pen information configured by the pen information configuration unit 1203 to the information processing apparatus 13. The pen information transmission unit 1204 can be realized by wireless or wired communication means. In particular, it is preferable to implement with wireless communication means. However, it may be realized by broadcasting means.

  The pen information receiving unit 1301 receives pen information from the electronic pen 12. The pen information receiving unit 1301 may receive pen information indirectly from the electronic pen 12. Indirect pen information is received when there is a communication device or the like that transfers pen information between the electronic pen 12 and the information processing device 13. The pen information receiving unit 1301 can be realized by a wireless or wired communication unit. In particular, it is preferable to implement with wireless communication means. However, you may implement | achieve by the means to receive broadcast.

  The description information acquisition unit 1302 acquires description information, which is information described with an electronic pen, from coordinate information included in one or more pieces of pen information. The description information is composed of, for example, a character code. The description information may be bitmap data or the like. The description information acquisition unit 1302 can usually be realized by an MPU, a memory, or the like. The processing procedure for the written information acquisition unit 1302 to acquire information is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The time acquisition unit 1303 acquires the time when the pen information reception unit 1301 receives the pen information. The time acquisition unit 1303 holds a clock and acquires time from the clock. The time acquisition unit 1303 can usually be realized by an MPU, a memory, or the like. The processing procedure for the time acquisition unit 1303 to acquire the time is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The score calculation unit 1304 calculates the score of the description information based on the description information acquired by the description information acquisition unit 1302 and the time acquired by the time acquisition unit 1303. A specific example of the method for calculating the score will be described later. The score calculation unit 1304 normally determines whether or not the held answer matches the description information acquired by the description information acquisition unit 1302, and calculates the score. At that time, the score calculation unit 1304 performs processing such as not calculating the pen information received after a certain period of time after receiving the pen information for the first time. The score calculation unit 1304 can be usually realized by an MPU, a memory, or the like. The processing procedure for the score calculation unit 1304 to calculate the score is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The score accumulation unit 1305 accumulates the score calculated by the score calculation unit 1304 in association with the pen identifier included in the pen information. The recording medium in which the score accumulation unit 1305 accumulates information may be built-in or may be externally attached. The process in which the score accumulation unit 1305 accumulates information is usually realized by software, but may be realized by hardware (dedicated circuit).

  The input receiving unit 1306 receives an output instruction that is an instruction to output score information. The output instruction usually has a pen identifier. The input means may be anything such as a numeric keypad, keyboard, mouse or menu screen. The input receiving unit 1306 can be realized by a device driver for input means such as a numeric keypad and a keyboard, control software for a menu screen, and the like.

  The score output unit 1307 outputs the score information accumulated by the score accumulation unit 1305 based on the output instruction received by the input reception unit 1303. The score output unit 1307 normally outputs a score corresponding to the pen identifier included in the output instruction. The output is a concept including display on a display, printing on a printer, sound output, transmission to an external device, and the like. The score output unit 1307 may be considered as including or not including an output device such as a display or a speaker. The score output unit 1307 can be implemented by output device driver software, or output device driver software and an output device.

  Hereinafter, the operation of the information processing system will be described. The operation of the electronic pen 12 will be described with reference to the flowchart of FIG.

  (Step S301) The coordinate information acquisition unit 1202 determines whether an image has been acquired. The video is, for example, video acquired by the camera of the electronic pen 12 in FIG. If the video is acquired, the process goes to step S302. If the video is not acquired, the process returns to step S301.

  (Step S302) The coordinate information acquisition unit 1202 configures coordinate information from the video acquired in step S301 and / or the video acquired previously.

  (Step S303) The pen information configuration unit 1203 acquires the pen identifier in the pen identifier storage unit 1201.

  (Step S304) The pen information configuration unit 1203 configures pen information from the coordinate information configured in step S302 and the pen identifier acquired in step S303.

  (Step S305) The pen information transmission unit 1204 transmits the pen information configured in step S304 to the information processing apparatus 13. Note that the pen information transmission unit 1204 holds the IP address of the information processing apparatus 13 and the like. The process returns to step S301.

  In the flowchart of FIG. 3, the process is terminated by an interruption such as power off or process termination.

  In the flowchart of FIG. 3, information described with the electronic pen 12 may be a character or a graphic. Further, the process of constructing the coordinate information from the video acquired by the camera is possible using, for example, the above-mentioned special paper (dedicated paper) manufactured by Anoto Co., Ltd., and is a known technique, and thus detailed description thereof is omitted.

  Further, in the flowchart of FIG. 3, the electronic pen 12 transmits pen information having coordinate information to the information processing apparatus 13. In such a case, the information processing apparatus 13 recognizes characters and figures from the coordinate information. However, the electronic pen 12 may recognize characters and figures from the coordinate information and transmit the recognized character data and the like to the information processing device 13. In addition, since the process which determines a character code from several coordinate information is the existing technique of character recognition, detailed description is abbreviate | omitted.

  Next, the operation of the information processing apparatus 13 will be described with reference to the flowcharts of FIGS. First, the operation of the information processing apparatus 13 will be described using the flowchart of FIG.

  (Step S401) The pen information receiving unit 1301 determines whether pen information has been received. If the pen information is received, the process proceeds to step S402. If the pen information is not received, the process jumps to step S404.

  (Step S402) The time acquisition unit 1303 acquires the current time.

  (Step S403) The pen information acquired in step S401 and the time acquired in step S402 are paired and stored. This accumulation may be a temporary accumulation. The process returns to step S401. In the process of looping from step S401 to step S403, one or more pairs of pen information and time to be accumulated are accumulated in the data structure such as an array while shifting the array counter.

  (Step S404) The input reception unit 1306 determines whether an instruction to output a score has been received. If an instruction to output a score is received, the process goes to step S405. If an instruction to output a score is not received, the process returns to step S401. Usually, this input includes a pen identifier (information for identifying a respondent such as a test or a correction question).

  (Step S405) A description information acquisition routine is executed. In the description information acquisition routine, the description information acquisition unit 1302 acquires description information from the one or more pen information accumulated in step S403. The description information acquisition routine will be described with reference to the flowchart of FIG.

  (Step S406) A score calculation routine is executed. In the score calculation routine, the score calculation unit 1304 calculates the score, and the score storage unit 1305 stores the score. The score calculation routine will be described with reference to the flowchart of FIG.

  (Step S407) The score output unit 1307 outputs the score calculated in step S406.

  Next, the operation of the description information acquisition routine of the information processing apparatus 13 will be described using the flowchart of FIG. Note that the description information acquisition routine 1302 performs all processing of the description information acquisition routine.

  (Step S501) 1 is substituted into the counter i.

  (Step S502) 0 is substituted for the start time. The start time is a variable.

  (Step S503) It is determined whether or not the i-th data is stored. If the i-th data is stored, the process goes to step S504. If the i-th data is not stored, the written information acquisition routine is terminated. Return. Data is data having pen information (pen identifier, coordinate information) and time.

  (Step S504) The coordinate information which i-th data has is acquired.

  (Step S505) The pen identifier included in the i-th data is acquired.

  (Step S506) The time which i-th data has is acquired.

  (Step S507) It is determined whether or not the start time is zero. If the start time is 0, the process goes to step S508, and if the start time is not 0, the process jumps to step S509.

  (Step S508) The time acquired in Step S506 is substituted for the start time.

  (Step S509) From the coordinate information acquired in step S504 and the coordinate information temporarily stored in step S518, it is determined whether or not the character is a delimiter. Since a technique for determining whether or not a character or the like is separated from the coordinate information of the locus of the electronic pen 12 is a known technique, a description thereof is omitted here. If it is a character delimiter, the process goes to step S510, and if it is not a character delimiter, the process jumps to step S518.

  (Step S510) A character code or the like is constructed from the set of coordinate information acquired in Step S504 and the coordinate information temporarily stored in Step S518.

  (Step S511) The character code and the like constructed in Step S510 are temporarily stored in the buffer.

  (Step S512) It is determined whether or not the answer is a delimiter. If it is an answer delimiter, the process goes to step S513, and if it is not an answer delimiter, the process jumps to step S517. There are various algorithms for determining whether or not the answer is delimited. For example, when the answer candidate data is determined by “O” and “X”, or in the alternative, the delimiter of the character or the like becomes the delimiter of the answer. When the answer is a sentence, it is possible to determine that the previous character code string was the answer after reading the next coordinate information.

  (Step S513) An answer number is determined from the coordinate information before conversion into a character code or the like. Note that the information processing apparatus 13 holds in advance information regarding correspondence between coordinate information (region) where an answer can be written and an answer number. Then, the information processing device 13 determines a response number from the information and the received coordinate information.

  (Step S514) The time acquired in step S506 is substituted for the end time. Note that the end time is a variable.

  (Step S515) The pen identifier acquired in Step S506, the answer number determined in Step S513, the answer, the start time, and the end time are temporarily stored as a pair.

  (Step S516) 0 is substituted for the start time of the variable.

  (Step S517) The counter i is incremented. The process returns to step S501.

  (Step S518) The coordinate information is temporarily stored. Go to step S517.

  Next, the operation of the score calculation routine of the information processing apparatus 13 will be described using the flowchart of FIG.

  (Step S601) 0 is substituted for a score which is a variable.

  (Step S602) A pen identifier is acquired from the data temporarily stored in the description information acquisition routine. This data is data in which the pen identifier, answer number, start time, and end time temporarily stored in step S515 in the flowchart of FIG. 5 are paired.

  (Step S603) 1 is substituted into the counter i.

  (Step S604) The start time of the first data is acquired. This data is also a paired data of the pen identifier, answer number, answer, start time, and end time temporarily stored in step S515 of the flowchart of FIG. Here, it is assumed that the start time of the first data is the start time of the test. Note that another method may be used for determining the start time.

  (Step S605) It is determined whether or not the i-th data exists. If the i-th data exists, the process goes to step S606, and if the i-th data does not exist, the score calculation routine ends. Return.

  (Step S606) Information on the end time of the i-th data is acquired.

  (Step S607) Based on the start time acquired in step S604 and the end time acquired in step S606, it is determined whether or not the answer is described within the test time (answer time). If it is described within the answer test time, the process goes to step S608, and if not described within the test time, the process jumps to step S613.

  (Step S608) The answer number of the i-th data is acquired.

  (Step S609) An answer corresponding to the answer number acquired in step S608, which is stored in a means (not shown), is acquired. In the means not shown, one or more answer numbers and answer information are stored in pairs.

  (Step S610) An i-th data answer is acquired.

  (Step S611) It is determined whether or not the answer acquired in Step S609 matches the answer acquired in Step S610. If they match, the process goes to step S612, and if they do not match, the process jumps to step S613.

  (Step S612) A fixed score is added to the score. Here, it is assumed that the score given to the correct answer is a fixed score. However, other methods may be used for the score addition method.

  (Step S613) The counter i is incremented.

  In the flowchart of FIG. 6, the pen identifier and the score are returned upon return. The operation for calculating the score by the information processing apparatus 13 has been described above using the flowcharts of FIGS. 4 to 6. In the above score calculation method, only the answers within a certain time from the test start time are validated, and the score is calculated. However, other score calculation methods may be used. For example, normally, a score of 10 points is given for each correct answer, but an answer that takes time may be processed so that even if the answer is correct, a point deducted according to the time is given.

  Hereinafter, a specific operation of the information processing system in the present embodiment will be described. A conceptual diagram of the information processing system is shown in FIG.

  Assume that a test taker starts answering the test shown in FIG. 7 with an electronic pen. This test is a test taken at home. This test is a test with a time limit of 15 minutes. The answer to this test is “◯” or “×”.

  The examination student's examination number is “123456”. The examination number of the student is held by the electronic pen as a pen identifier.

  In such a case, the electronic pen configures pen information having a structure as shown in FIG. 8, and constantly transmits the information to the information processing apparatus regularly. The pen information includes a pen identifier and coordinate information. The coordinate information is information indicating the position of the electronic pen on the test sheet.

  Then, the electronic pen sequentially transmits information on the locus moved on the test sheet (one or more pieces of information having the structure of FIG. 8) to the information processing apparatus. Then, the information processing apparatus receives pen information transmitted from the electronic pen. Then, the information processing apparatus temporarily stores the pen information and the time when the pen information is received as a pair. FIG. 9 shows an example of a set of pen information and time pair information received from the electronic pen by the information processing apparatus. FIG. 9 includes “ID”, “pen identifier”, “coordinate information”, and “time”. “ID” is information necessary for record management.

  Next, the information processing apparatus converts the coordinate information group included in the data set illustrated in FIG. 9 into a character code (answer). Then, an answer (“◯” or “×”) described by the student is obtained. Then, the answer number of the answer is determined from the coordinate information group included in the data set shown in FIG.

  Next, the response start time and end time are acquired from the time information of the data set shown in FIG. Then, the answer information of the students having “ID”, “pen identifier”, “answer number”, “answer”, “start time”, and “end time” is temporarily stored.

  Further, it is assumed that the information processing apparatus holds information on the test answer shown in FIG. The test answer information stores at least one record having “answer number” and “answer”.

  Next, the information processing apparatus calculates a test score from the data in FIG. 10 and the test answer information in FIG. In this case, since the time limit is 15 minutes, 15 minutes after the start time “2/11 14:02:01” of the record of “ID = 1” in the table of FIG. 10, that is, “2/11 14:17”. “Answer” included in a record having a value of “end time” greater than 0:00 is not calculated as a score. Therefore, the information processing apparatus considers the “answer” from “ID = 1” to “ID = 7” of the data in FIG. 10 in the score calculation process.

  Then, the information processing apparatus determines that the number of correct answers is “6” (“ID = 1”) from the “answer” of “ID = 1” to “ID = 7” in the data of FIG. 10 and the answer of the test shown in FIG. To “ID = 7” and “ID = 4” answers are excluded). Further, it is assumed that the information processing apparatus holds “10 points” for each correct answer. Then, the information processing apparatus calculates a score “60 points”.

  Next, the information processing apparatus outputs an examination number and a score as shown in FIG.

  As described above, according to the present embodiment, information is received from an electronic pen, and a score is calculated based on the received information and time information that is information related to the time at which the information is received or the time at which the information is described with the electronic pen. Is possible. With this information processing system and scoring method, it is possible to score in consideration of time, as in a test performed at a test site, in correspondence education and correction at home. Thus, important tests can be performed at home. In distance learning, it is possible to score in consideration of the test time. Furthermore, it is possible to score in consideration of the speed and time of answers, which has been difficult until now.

  According to the specific example in the present embodiment, the start time of the test was the time when the first answer was described, but the name and the examination number were described, and the time when the description of the name and the like was started It may be the start time of the test. The same applies to other embodiments.

  Further, according to the present embodiment, the information processing apparatus acquires the time. However, even if the electronic pen or another information processing apparatus transmits pen information to which the time information that is time information is added to the information processing apparatus. good. This also applies to other embodiments.

  Moreover, according to this Embodiment, after receiving information first from an electronic pen, the information received after progress for a fixed time was a form which is not considered in scoring. However, as long as it is a scoring method that receives information from an electronic pen and calculates a score based on the received information and time information that is information on the time at which the information is received or the time at which the information is described with the electronic pen, good. For example, each time, the score may be calculated by processing such as giving a low score even if the answer is correct. This also applies to other embodiments.

  In the present embodiment, the electronic pen transmits coordinate information to the information processing apparatus, and the information processing apparatus configures a character code or the like from the coordinate information. It may be performed by a pen or other information processing apparatus. In such a case, the information processing apparatus receives information such as a test answer from the electronic pen or another information processing apparatus using a character code or the like.

  Further, in the present embodiment, it is assumed that the test answers are answered in the order of the questions, but the order of the answers is not limited. That is, in the present embodiment, for the sake of simplification of explanation, the explanation is merely based on the assumption that answers are made in the order of the problems. The same applies to other embodiments.

  In this embodiment, when the information processing apparatus determines that the answer is correct, the condition is that the answer matches the held answer, but other conditions may be used. The same applies to other embodiments.

Furthermore, the processing in the present embodiment may be realized by software. Then, this software may be distributed by software download or the like. Further, this software may be recorded and distributed on a recording medium such as a CD-ROM. This also applies to other embodiments in this specification. Note that the software that implements the information processing apparatus according to the present embodiment is the following program. In other words, the program includes a pen information receiving step for receiving one or more pen information having a pen identifier, which is information for identifying the electronic pen from the electronic pen, and coordinate information indicating the locus of the electronic pen, and one or more A description information acquisition step for acquiring description information that is information described with an electronic pen from the coordinate information of the pen information, a time acquisition step for acquiring time, a description information acquired in the description information acquisition step, and a time acquisition step This is a program for executing a score calculation step for calculating the score of written information based on the time acquired in step (1) and a score accumulation step for accumulating the score calculated in the score calculation step in association with a pen identifier.

Specifically, the score calculation unit 13304 determines the score depending on the correct / incorrect answer of the test, the time required for the answer, whether the answer has been erased many times, or whether the answer has been answered correctly once, etc. Is calculated. The score calculation unit 13304 can be usually realized by an MPU, a memory, or the like. The processing procedure for the score calculation unit 13304 to calculate the score is usually realized by software, and the software is recorded in a recording medium such as a ROM.

In addition, the start time determination method may be other methods as in the first embodiment.

  (Step S1406) It is determined whether i-th data exists. If the i-th data exists, the process proceeds to step S1407, and if the i-th data does not exist, the process jumps to step S1421.

  (Step S1407) The information of the end time which i-th data has is acquired.

  (Step S1408) The information of the end time closest to the end time information included in the i-th data is acquired. This end time is the time when the answer made immediately before is ended.

  (Step S1409) The answer time for this question is calculated from the end time of step S1407 and the end time of step S1408.

  (Step S1410) Based on the test start time acquired in step S1405 and the end time acquired in step S1407, it is determined whether or not the test time (answer time) is entered. If it is described within the test time, the process goes to step S1411. If not described within the test time, the process jumps to step S1420.

  (Step S1411) The answer number of the i-th data is acquired.

  (Step S1412) An answer corresponding to the answer number acquired in step S1411, which is stored in a means not shown, is acquired. The means not shown stores at least one answer number, answer, and score (scoring for the problem) in pairs.

  (Step S1413) An i-th data answer is acquired.

  (Step S1414) It is determined whether or not the answer acquired in step S1412 matches the answer acquired in step S1413. If they match, the process goes to step S1415, and if they do not match, the process jumps to step S1421.

  (Step S1415) A score corresponding to the answer number acquired in step S1411 is acquired.

  (Step S1416) The number of answers corresponding to the answer number acquired in step S1411 is acquired. The number of responses is the number of times incremented in step S1419.

  (Step S1417) A score for the problem is calculated based on the answer time, the number of answers, and the score. If the score is calculated using the answer time, the number of answers, and the score as parameters, the method for calculating the score is not limited. That is, “score = f (scoring, number of responses, response time)”.

  In the flowchart of FIG. 14, the pen identifier and the total score are returned upon return.

  Hereinafter, a specific operation of the information processing system in the present embodiment will be described. A conceptual diagram of the information processing system is shown in FIG.

  Now, as in the first embodiment, it is assumed that a test taker starts answering the test shown in FIG. 7 with an electronic pen. This test is a test taken at home. This test is a test with a time limit of 30 minutes. The answer to this test is “◯” or “×”. The examination student's examination number is “123456”. The examination number of the student is held by the electronic pen as a pen identifier. In such a case, the electronic pen configures the pen information shown in FIG. 8 and regularly transmits it to the information processing apparatus. Then, the information processing apparatus receives pen information transmitted from the electronic pen. FIG. 15 shows data composed of pen information received by the information processing apparatus. The process of configuring the data in FIG. 15 is the same as the process described in the first embodiment except for “answer time”.

  The “answer time” is calculated as follows. First, it is assumed that the test start time is “2/11 14:00”. The information processing device holds the start time of this test in advance. Then, the “answer time” of the record of “ID = 1” is “2:10” (2 minutes 10 seconds) from the test start time held in advance and the “end time” of the record of “ID = 1”. Can be calculated. Further, the “answer time” of the records after “ID = 2” can be calculated from the difference between the “end end time” of the immediately preceding record and the “end end time” of the record. That is, the “answer time” of the “ID = 2” record can be calculated from “14: 05: 03-14: 02: 10” to “2:53”. The data in FIG. 15 is obtained by the above processing.

  Next, it is assumed that the information processing apparatus holds information on answers and scoring for the answer numbers shown in FIG. According to FIG. 16, the answer to the question “1” is “◯” and the score is “10”.

  Next, processing in which the information processing device scores based on the data in FIGS. 15 and 16 will be described. In the scoring process, the information processing apparatus forms the scoring process intermediate table of FIG. The scoring processing interim table holds records having “answer number”, “correct / wrong”, “answer time”, “number of answers”, “scoring”, and “score” for the number of the problem. “Answer number” corresponds to the number in question. “Correct” is information indicating whether the answer is correct or incorrect. “Answer time” is the total time spent working on the problem. “Number of answers” indicates the number of times the question was answered. “Scoring” is the problem scoring and is obtained from the table of FIG. “Score” is a score given by “score = f (scoring, number of responses, response time)”.

  Now, the “answer” in FIG. 15 and the “answer” in FIG. 16 are added together to obtain “correct” for each question. “Correct” is determined by determining whether or not the answer of “until 2:30 14:30” within the time period is valid, and whether the final “answer” matches the “answer” in FIG. obtain. That is, in the table of FIG. 15, the information of “ID = 14” answered after the test time (30 minutes) is ignored. The “answer time” is the total answer time corresponding to the answer number of valid information. This information is also acquired from FIG. Specifically, for example, “answer time” of “answer number = 4” is a total of answer times “2:42” and “3:09” included in the records of “ID = 4” and “ID = 13”. “5:51”. The “answer count” is the number of records with one answer number. The “answer count” of “answer number = 4” is “2”.

  Further, the “score” is calculated by the following calculation formula, for example. The calculation formula is “score = scoring / (number of responses * g (response time))”. “G (answer time)” is an integer obtained by truncating information of “1” when the answer time is “0 to 1:59”, and otherwise “second”. Specifically, the “score” of “answer number = 4” is “10 / (2 * 5) = 1”. As described above, the information processing apparatus can calculate a score for each problem.

  Next, the information processing apparatus adds up all the scores for each problem, calculates “73 points”, and outputs the result.

  As described above, according to the present embodiment, it is possible to calculate the score in consideration of the behavior of the electronic pen and the time for describing the information based on the information transmitted from the electronic pen. With this information processing system and scoring method, scoring in consideration of the speed of answers and the behavior of students is possible.

  That is, the scoring method in the present embodiment is a scoring method for test answers written with an electronic pen, which receives information from the electronic pen, receives the received information, behavior obtained from the information, and information Is a scoring method for calculating a score based on the information of the time at which is received.

  In the present embodiment, the number of answers is given as an example of the behavior obtained from the received information, but other information may be used. For example, the behavior may be the order in which the problem is solved. Further, the behavior may be to determine whether extra information other than the test answer is described. In other words, the scoring method described in the present embodiment is a scoring method for a test answer written with an electronic pen, and is a behavior that is information about an answer and behavior received from the electronic pen. This is a scoring method that obtains information and calculates a score based on the answer and behavior information.

Further, the plurality of processes of the information processing apparatus described in the first embodiment and the second embodiment may be shared by two or more apparatuses. The same applies to the following embodiments.

  The information processing apparatus 193 includes a pen information receiving unit 1301, a description information acquiring unit 19302, a score calculating unit 19304, a score accumulating unit 1305, an input receiving unit 1306, and a score output unit 1307.

  The description information acquisition unit 19302 acquires information described with the electronic pen and the description order from the coordinate information of one or more pieces of pen information, and configures behavior information from the information. The behavior information here is information having information written with an electronic pen and a stroke order (writing order), and the data structure or the like is not limited. The description information acquisition unit 19302 can be usually realized by an MPU, a memory, or the like. The processing procedure for the description information acquisition unit 19302 to configure information is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The score calculation unit 19304 calculates a score based on the behavior information acquired by the written information acquisition unit 19302. Specifically, the score calculation unit 19304 determines whether or not the stroke order indicated by the behavior information is correct, and calculates the score based on the determination. In addition, although the score calculation part 19304 normally stores the information regarding the stroke order used as a correct answer previously, you may make an inquiry to other apparatuses. The score calculation unit 19304 can be usually realized by an MPU, a memory, or the like. The processing procedure for the score calculation unit 19304 to calculate the score is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  Hereinafter, the operation of the information processing system will be described. The operation of the electronic pen 12 has been described. The operation in which the information processing device 193 acquires stroke order information from the pen information and calculates the score will be mainly described with reference to the flowchart of FIG. Other operations of the information processing device 193 are the same as those in the first embodiment.

  (Step S2001) 1 is substituted into the counter i.

  (Step S2002) 0 is substituted into the flag.

  (Step S2003) It is determined whether the pen information receiving unit 1301 has received pen information. If the pen information is received, the process goes to step S2004. If the pen information is not received, the process returns to step S2003.

  (Step S2004) The written information acquisition unit 19302 determines whether or not a stroke is started from the pen information (coordinate information) received in step S2003 and / or the stored pen information (coordinate information). If it is the start of a stroke, it will go to step S2005, and if it is not the start of a stroke, it will fly to step S2007. There are various algorithms for determining whether or not the stroke is started from the pen information (coordinate information). The first coordinate information (coordinate information when the flag is 0) is the start of a stroke. If the vector (direction) obtained from the (i-1) th end point and the point before the end point differs from the vector (direction) obtained from the (i-1) th end point and the coordinate information received in step S2003. If (or if not approximated), the coordinate information received in step S2003 may be determined to be the start of a stroke. There are various other methods for determining the coordinates of the start of the stroke. Note that the start of a stroke refers to the start of the description of one side of a character such as kanji or hiragana.

  (Step S2005) The coordinate information of the pen information received in step S2003 is accumulated as the i-th starting point.

  (Step S2006) 1 is substituted into the flag. A flag of 1 indicates that characters are being written. The process returns to step S2003.

  (Step S2007) The written information acquisition unit 19302 determines whether or not the stroke is ended from the pen information (coordinate information) received in step S2003 and the stored pen information (coordinate information). If the stroke ends, the process goes to step S2008, and if not, the process jumps to step S2011. There are various algorithms for determining whether or not the stroke is finished from the pen information (coordinate information). First, if the vectors (directions) obtained from three points (three coordinate values) including the preceding and following points are different (or not approximated), it is determined that the coordinate information of the midpoint is the end of the stroke. obtain. There are various other methods for determining the coordinates of the end of the stroke. Note that the end of the stroke refers to the end of the description of one side of a character such as kanji or hiragana.

  (Step S2008) The coordinate information of the pen information received in step S2003 is stored as the i-th end point.

  (Step S2009) i is incremented by one.

  (Step S2010) The i-th starting point is accumulated. The i-th start point is, for example, the next point (coordinates) after the (i−1) -th end point. The process returns to step S2003.

  (Step S2011) The written information acquisition unit 19302 determines whether or not it is the end of the character. For example, when pen information is not received for a certain time or more, it is determined that the character is finished. In addition, when the user knows the final coordinates of the character and receives pen information including information on the coordinates, it is determined that the character has ended. In addition, there are various methods for determining whether or not the character is finished.

  (Step S2012) Coordinate information is temporarily stored. The process returns to step S2003.

  (Step S2013) The i-th end point is accumulated.

  (Step S2014) 1 is substituted into the counter i.

  (Step S2015) It is determined whether or not the i-th stroke data exists. If the i-th data exists, the process goes to step S2016, and if the i-th data does not exist, the process jumps to step S2020.

  (Step S2016) Information (coordinate information) of the i-th start point and end point of the response acquired from the received pen information is acquired.

  (Step S2017) The i-th start point and end point information (coordinate information) is acquired from the stored answer information.

  (Step S2018) It is determined whether or not the coordinate information group (start point and end point information) acquired in step S2016 matches or approximates the coordinate information group (start point and end point information) acquired in step S2017. If they match or approximate, the process goes to step S2019. If they do not match and do not approximate, the process jumps to step S2021.

  (Step S2019) The counter i is incremented by one.

  (Step S2020) 10 is substituted into the score.

  (Step S2020) 0 is substituted into the score.

  In the flowchart of FIG. 20, the operation for scoring the stroke order of one character has been described. Therefore, no score is output in the flowchart of FIG. Usually, in a test, whether or not a plurality of strokes are correct is determined and output, but such processing is possible by repeating the operation of the flowchart of FIG. 20 and outputting the added score. In the flowchart of FIG. 20, it is preferable to return the flag to 0 before the end. This is for determining whether the next character is in the correct stroke order.

  Hereinafter, a specific operation of the information processing system in the present embodiment will be described. A conceptual diagram of the information processing system is shown in FIG. The information processing system includes the medium 11, the electronic pen 12, and the information processing device 193. In this specific example, the test of the writing order is performed using the paper of the medium 11 (the above-described paper on which special dots are printed). This test is a test for judging the correctness of the stroke order of the Chinese character “mouth”.

  Now, after writing the examination number using the electronic pen 12, the user traces the “mouth” indicated by the broken line and writes the “mouth” in the order written in accordance with the instruction written on the test paper 11.

  Then, the electronic pen 12 continuously transmits the pen information having the coordinate information and the pen identifier “2345” to the information processing device 193. An example of pen information transmitted by the electronic pen 12 is shown in FIG. In FIG. 22, “ID” is an identifier of a record attached for convenience of explanation.

  The information processing device 193 that has received the pen information group in FIG. 22 acquires the four strokes constituting the mouth by the above-described stroke detection method. The starting point of the first stroke is (10, 50). The starting point of the first stroke is coordinate information included in the pen information received first. The end point of the first stroke is (11,100). The end point of the first stroke can be extracted from the coordinate information before and after the two vectors are completely different. By such processing, the coordinate information of the start point and end point of the second to fourth strokes can be acquired.

  In addition, FIG. 24 shows a coordinate information group indicating the answer of the stroke order of “mouth” held by the information processing device 193.

  Then, the information processing device 193 compares the coordinate information group in FIG. 23 and the coordinate information group in FIG. 24 and, if they match or approximate, the writing order written by the test respondent is Judge that it is correct. Since the coordinate information group in FIG. 23 and the coordinate information group in FIG. 24 are very close now, the information processing apparatus 193 determines that the writing order written by the test respondent is correct. The determination of whether or not they are approximate is performed, for example, as follows. All start points and end points are compared, and if the distance between the two points is less than a certain value, it is assumed that they are approximate. It should be noted that other methods may be used as a method for determining whether or not they are approximate.

  Then, the information processing device 193 adds the score from the comparison result and outputs the result. The output mode of the score is not limited.

  As described above, according to the present embodiment, by the scoring method of receiving information from the electronic pen, acquiring behavior information that is information related to behavior such as the stroke order from the received information, and calculating a score based on the behavior information , Flexible scoring using the characteristics of electronic pens.

  In the present embodiment, the behavior information is mainly described in the stroke order, but other information may be used. The behavior information may be information indicating the number of answers and the order in which the problems are solved. Further, the behavior information may be information generated by determining whether extra information is not described in the test.

  According to the present invention, flexible scoring using the characteristics of the electronic pen is achieved by a scoring method that receives information from the electronic pen and calculates a score based on the received information and the time when the information is received. This is effective as an information processing system using an electronic pen.
