For example, the medium 11 has a special dot pattern printed thereon. The medium 11 is usually made of paper, but characters and the like can be described with the electronic pen 12. For example, as long as a special dot pattern is printed, any material such as plastic may be used. The teaching material elements are characters, character strings, figures, images, and the like. “Trace” means that the electronic pen 12 is run on the teaching material element printed on the medium 11 (described as the electronic pen 12).
That is. The “instruction” is an action of checking, pressing, or adding a dot to the teaching material element with the electronic pen 12. The teaching material element printed on the medium 11 may be a solid line, a broken line, or a light gray character or figure. In addition, information other than the teaching material element may be printed on the medium 11.

The above coordinate information is acquired from the coordinate information group which comprises 1st teaching material element information. Then, the acquired one or more pieces of coordinate information are additionally written on the memory.

  (Step S605) The first teaching material element information acquisition unit 1332 increments the counter i by one. The process returns to step S602.

  In the flowchart of FIG. 6, the counter i is incremented. In step S603, the first teaching material element information acquisition unit 1332 acquires coordinate information that is closest to the last coordinate information, and in step S604. One or more pieces of coordinate information from the first coordinate information of the first learning material element information to the acquired coordinate information may be acquired from the coordinate information group constituting the first learning material element information. In such a case, loop processing does not occur.

  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.

  FIG. 7 is an example of the medium 11. FIG. 7 is a teacher's sheet used in a science lecture.

  Further, the learning material element information storage unit 131 of the information output device 13 holds a learning material element information management table shown in FIG. The learning material element information management table is a table for managing learning material element information. The learning material element information management table of FIG. 8 is information obtained by digitizing the learning material elements constituting the medium 11 of FIG. The learning material element information management table stores one or more records having attributes of “ID”, “coordinate information group”, “data”, and “learning material element classification information”. “ID” is information for identifying a record and exists for record management in the table. The “coordinate information group” is one or more pieces of coordinate information (X, Y) constituting the teaching material element information. The coordinate information (X, Y) is information indicating a position on the medium 11. “Data” is data that can be configured from a coordinate information group and is output data. “Teaching material element classification information” is information for classifying the type of teaching material element information, “0” being first learning material element information to be traced, and “1” being second learning material element information to be instructed. It is.

  In such a situation, suppose that the teacher conducts a science class for the students. In addition, the teacher holds the electronic pen 12 and uses the electronic pen 12 to trace or instruct (check or mark) the figure or character string on the medium 11 in FIG. Suppose, however, that science classes are to be promoted.

  Now, at the beginning of the science class, the teacher says "Let's study about making angiosperm flowers today." Specify one of the areas (check, etc.). Then, the description information acquisition unit 121 of the electronic pen 12 displays a coordinate information group “(x1, y1) (x2, y2)... (Xa, ya)... (Xn, yn)” indicating the checked locus. And placed on the memory of the electronic pen 12. Then, for example, in accordance with a teacher's instruction (checking the transmission area of the medium 11, pressing the transmission button in the electronic pen 12, etc.), the written information transmission unit 122 causes the coordinate information group “(x1, y1) ( x2, y2)... (xa, ya)... (xn, yn) ”is transmitted to the information output device 13. Here, the coordinate information group “(x1, y1) (x2, y2)... (Xa, ya)... (Xn, yn)” is the description information. Without the teacher's instruction, the written information transmission unit 122 reads the coordinate information group “(x1, y1) (x2, y2)... (Xa, ya)... (Xn, yn)” on the memory. The information may be transmitted to the information output device 13 one after another.

  Next, the description information receiving unit 132 of the information output device 13 receives the coordinate information group “(x1, y1) (x2, y2)... (Xa, ya)... (Xn, yn)”.

  Next, the teaching material element type judging means 1331 uses the coordinate information ““ x1, y1) (x2, y2)... (Xa, ya)... (Xn, yn) ”in the middle. (Xa, ya) "is acquired. Then, the learning material element type determination means 1331 reads the first learning material element information “(10, 10) (10, 11)...” From the learning material element information management table of FIG. Next, the teaching material element type determination unit 1331 acquires the acquired coordinate information in the coordinate information group “(10, 10) (10, 11)... It is determined whether or not “(xa, ya)” is included. Here, it is assumed that “(xa, ya)” is included in the coordinate information group “(10, 10) (10, 11).

  Then, the learning material element type determination unit 1331 acquires learning material element classification information “1” corresponding to the first learning material element information. The learning material element classification information “1” indicates that the learning material element information is second learning material element information.

  Next, the second learning material element information acquisition means 1333 obtains the first learning material element information “(10, 10) (10, 11)...” Corresponding to the received description information as the learning material element information of FIG. Obtain from the management table. Here, the second teaching material element information acquisition unit 1333 may acquire the data “production of angiosperm flowers”.

  Next, the second output means 1342 outputs the acquired teaching material element information. That is, the second output means 1342 normally constructs the character string “Angiosperm Flower Production” from “(10, 10) (10, 11)... , 11)... "Is output at the position indicated by the character string“ Angiosperm Flower Production ”. The output mode is shown in FIG. In FIG. 9, “Making angiosperms” is transmitted from the electronic pen 12 to the information output device 13 and output by the projector. Many students are taking classes.

  Next, the teacher instructs “angiosperms” and “...” Of the medium 11 in FIG. And the information output device 13 outputs "Angiosperm ..." similarly.

  Then, the teacher traces with the electronic pen 12 the character string “ovule is in the ovary ...” on the medium 11 in FIG. Then, the description information acquisition unit 121 of the electronic pen 12 obtains the coordinate information group indicating the traced trajectory and arranges it on the memory of the electronic pen 12. Then, the written information transmitting unit 122 transmits the coordinate information groups on the memory to the information output device 13 one after another.

  Next, the description information receiving unit 132 of the information output device 13 receives the coordinate information group “(xa, ya)... (Xb, yb). ... (Xc, yc) ”.

  Next, the teaching material element type determination means 1331 uses the coordinate information “(xb, yc)” in the middle of the coordinate information group “(xa, ya)... (Xb, yb). yb) ". The learning material element type determination means 1331 reads from the learning material element information management table of FIG. 8 from the first learning material element information “(10, 10) (10, 11). It is checked whether or not the information includes coordinate information that matches the coordinate information “(xb, yb)”. If the coordinate information does not match, the coordinate information “(xb1, yb1)” closest to the coordinate information “(xb, yb)” is acquired, and the point “(xb, yb)” and the point “(xb1, yb1) "distance d1 is calculated. Then, “1, d1” is stored.

  Then, the teaching material element type judging means 1331 includes coordinate information in the teaching material element information “(60, 30) (60, 31)...” Of “ID = 4” in the teaching material element information management table of FIG. The presence of “(xb, yb)” is detected.

  Then, the learning material element type determination means 1331 acquires learning material element classification information “0” corresponding to the fourth learning material element information. The learning material element classification information “0” indicates that the learning material element information is first learning material element information.

  Next, the first teaching material element information acquisition unit 1332 acquires “(xa, ya)” of the acquired coordinate information “(xa, ya)... (Xb, yb)... (Xc, yc)”. The coordinate information closest to “)” is acquired from the coordinate information group “(60, 30) (60, 31)...” Of “ID = 4” in the teaching material element information management table of FIG. Here, it is assumed that the first teaching material element information acquisition unit 1332 has acquired “(60, 31)”. Then, the first teaching material element information acquisition unit 1332 acquires the coordinate information “(60, 30) (60, 30)” from the first coordinate information “(60, 30)” of the coordinate information group “(60, 30). 60, 31) "is obtained from the coordinate information group of" ID = 4 "in the teaching material element information management table of FIG. 8 and stored in the memory. Append.

  And the process which acquires the coordinate information in the teaching material element information corresponding to each point of acquired coordinate information "(xa, ya) ...... (xb, yb) ...... (xc, yc)", Continue to point (xc, yc). Then, it is assumed that the first teaching material element information acquisition unit 1332 has obtained coordinate information “(60, 30) (60, 31)... (88, 37)”. “(88, 37)” is “Chong” of the final image of “ka” that constitutes hiragana “ga”.

  Next, the first output means 1341 outputs a point or a line corresponding to the acquired coordinate information “(60, 30) (60, 31)... (88, 37)”. In other words, the first output means 1341 constitutes and outputs an “ovule” from the acquired coordinate information “(60, 30) (60, 31)... (88, 37)”. Such an output mode is shown in FIG. The “ka” here is the stage before “ga” is completed.

  Then, the teacher describes the stamen, the pistil, the stigma and the like by tracing the medium 11 with the electronic pen 12 while the class is progressing. Then, by tracing or instructing all the character strings or pictures printed on the medium 11 with the electronic pen 12, the traced character strings or pictures, the instructed character strings or pictures, etc. are displayed on the display. The

  As described above, according to the present embodiment, a high-quality class can be performed regardless of the teacher's ability. In addition, classes can be conducted efficiently. In addition, the class said here is not limited to the class at school, but is a broad concept including lectures inside and outside the school and guidance. The class may be a distance class.

In addition, according to the present embodiment, the teaching material element information corresponding to the teaching material element on the medium 11 is output only by pointing the teaching material element on the medium 11 with the electronic pen 12. Therefore, the teacher does not need to write troublesome character strings or pictures during the lesson, and the lesson progresses efficiently.
Further, according to the present embodiment, since the medium is the teacher's own sub-note material, the teacher's own ability increases as the class is repeated.

  Further, according to the present embodiment, by tracing the teaching material elements on the medium 11 with the electronic pen 12, a traced character string or picture is output at the tracing speed. Therefore, the student can see the contents described by the teacher at a timing that matches the remarks of the teacher. In other words, you can create a situation where the teacher is writing on the blackboard. In addition, the teaching material elements that can be considered in the time when the teacher traces characters or pictures can be considered. On the other hand, the teaching material elements that do not need to be considered can be output only by checking by the teacher. Therefore, it is possible to conduct a class with an instinct.

  Further, according to the present embodiment, there are two types of teaching material element information: “0” of the first teaching material element information to be traced and “1” of the second teaching material element information to be instructed. There may be other types, and it may be divided into three or more types. The other type is, for example, a type of mode in which a handwritten one is output as it is when being traced. In such a case, the learning material element that outputs the stored learning material element when traced, the learning material element that is output by handwriting as traced, and the teaching material element stored when instructed are output There are three types of teaching material elements to do.

  Furthermore, according to the present embodiment, a particularly beautiful picture or character string that has been prepared is displayed simply by tracing the electronic pen 12 with a picture or character string that is difficult to describe. Therefore, the teacher's picture is not difficult to understand and the characters are difficult to read, and high-quality classes can be conducted regardless of the teacher's ability.

  According to the present embodiment, the teaching material element information storage unit 131 instructs the first teaching material element information output by tracing the medium 11 with the electronic pen 12 and the medium 11 with the electronic pen 12. Was mixed with the second teaching material element information output by. However, all of the teaching material element information existing in the learning material element information storage unit 131 may be the first learning material element information or all of the second learning material element information.

(Embodiment 2)

  In this embodiment, when a character string or figure written on a medium with an electronic pen is traced, an information processing system in which a traced character string is output will be described for different users. In this information processing system, for example, when a teacher is teaching a kanji, the kanji traced by the teacher is beautiful and the prepared electronic data is output, and the kanji traced by the student is output as traced. Process. In addition, for example, the teacher performs only the instruction, and the instructed character string or the like is output, but the student does not output the character string or the like unless the user traces.

  FIG. 1 is a conceptual diagram of an information processing system in the present embodiment. FIG. 11 is a block diagram of the information processing system in the present embodiment.

  The information processing system 2 includes a medium 11, an electronic pen 22, and an information output device 23.

  The electronic pen identifier storage unit 221 stores an electronic pen identifier that identifies the electronic pen 22. The electronic pen identifier may be anything such as a numeric string, alphabet string, or a mixture thereof. The electronic pen identifier storage unit 221 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium.

  The description information transmission unit 222 transmits the description information acquired by the description information acquisition unit 121 and the electronic pen identifier of the electronic pen identifier storage unit 221 to the information output device 23. The written information transmitting unit 222 is usually realized by a wireless or wired communication unit, but may be realized by a broadcasting unit.

  The determination unit 231 determines whether the electronic pen identifier received by the written information reception unit 132 is the first type for outputting the learning material element information stored in the learning material element information storage unit 131, or outputs the second as traced. Determine if it is a type. For example, the determination unit 231 stores one or more sets of electronic pen identifiers and types. Then, the determination unit 231 acquires a type that is paired with the electronic pen identifier received by the written information reception unit 132, and determines whether the type is the first type or the second type. Further, the determination unit 231 stores, for example, one or more electronic pen identifiers, determines whether the electronic pen identifier received by the description information reception unit 132 is stored, and stores the received electronic pen identifier. The first type may be determined. Conversely, the determination unit 231 may determine that the received electronic pen identifier is the second type. The first type is, for example, a teacher's electronic pen type. The second type is, for example, a student's electronic pen type. The determination unit 231 can usually be realized by an MPU, a memory, or the like. The processing procedure of the determination unit 231 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  When the determination unit 231 determines that the electronic pen identifier is the first type, the output unit 234 outputs the learning material element information acquired by the learning material element information acquisition unit 133, and the electronic pen identifier is the second type. If it is determined, the description information acquired by the description information receiving unit 132 is output as it is (as it is handwritten). Here, the output is mainly a display on a display or a projection using a projector, but a sound output, transmission to an external device, storage in a recording medium, other processing device or other program, etc. It is a concept including delivery of processing results. The output unit 234 may be considered as including or not including an output device such as a display. The output unit 234 can be realized by output device driver software, or output device driver software and an output device.

  When the determination unit 231 determines that the electronic pen identifier is the first type, the first output unit 2341 outputs a point or a line corresponding to the coordinate information acquired by the first teaching material element information acquisition unit 1332. When the electronic pen 12 traces the medium 11, the first output unit 2341 outputs educational material element information corresponding to the traced educational material element.

  When the determination unit 231 determines that the electronic pen identifier is the first type, the second output unit 2342 outputs the teaching material element information acquired by the second teaching material element information acquisition unit 1333. When the medium 11 is instructed with the electronic pen 12, the second output unit 2342 outputs educational material element information corresponding to the instructed educational material element.

  The third output unit 2343 outputs the description information acquired by the description information reception unit 132 when the determination unit 231 determines that the electronic pen identifier is the second type. The 3rd output means 2343 outputs as it is handwritten.

  Next, the operation of the information processing system will be described. First, the operation of the electronic pen 22 will be described. The description information acquisition unit 121 of the electronic pen 22 acquires an image of the electronic pen 12 scanned on the medium 11. And the description information acquisition part 121 comprises description information from the acquired image | video, and stores it temporarily on a storage medium. Then, the written information transmission unit 222 reads the electronic pen identifier from the electronic pen identifier storage unit 221. Next, the description information transmission unit 222 transmits the description information configured by the description information acquisition unit 121 and the read electronic pen identifier to the information output device 23. In addition, the description information transmission unit 222 may transmit the description information on the storage medium according to a user instruction, or may transmit the description information or the like as soon as the description information is stored in the storage medium. In addition, the user instruction includes a check of “send button” on the medium 11 and a press of a predetermined button of the electronic pen 22.

  Next, operation | movement of the information output device 23 is demonstrated using the flowchart of FIG. In the flowchart of FIG. 12, the description of the same steps as those of the flowchart of FIG. 4 is omitted.

  (Step S1201) The description information receiving unit 132 determines whether description information and an electronic pen identifier have been received. If description information etc. are received, it will go to step S1202, and if description information etc. are not received, it will return to step S1201. Note that the reception of the description information and the reception of the electronic pen identifier may not be performed simultaneously.

  (Step S1202) The determination unit 231 acquires the electronic pen identifier received in step S1201.

  (Step S1203) The determination unit 231 determines the type from the electronic pen identifier acquired in Step S1202, and arranges information indicating the type on the memory. Here, the type may be the first type or the second type. Further, the type is the type of the electronic pen 22, but it can be said that it is indirectly the type of the user of the electronic pen 22.

  (Step S1204) The output unit 234 determines whether or not the type determined in step S1203 is the first type. If it is the first type, go to Step S402, and if it is not the first type, go to Step S1205.

  (Step S1205) The third output unit 2343 acquires a coordinate information group from the description information received in Step S1201.

  (Step S1206) The third output means 2343 outputs the coordinate information group acquired in Step S1205. It can be said that the output of this coordinate information group is the output of the description information. This coordinate information group is information indicating the trajectory of the electronic pen 22 when handwritten with the electronic pen 22. The process returns to step S1201.

  In the flowchart of FIG. 12, the learning material element information is divided into the first learning material element information and the second learning material element information. In such a case, for example, teaching material element information corresponding to a character string or a graphic traced on the medium 11 by the teacher is output neatly. In addition, for example, the teaching material element information corresponding to the character string or graphic instructed on the medium 11 by the teacher is output neatly.

  Next, the description information receiving unit 132 of the information output device 23 receives the description information and the electronic pen identifier. Then, the determination unit 231 acquires the received electronic pen identifier “12345”. Then, the determination unit 231 determines that the acquired electronic pen identifier “12345” is a pre-held electronic pen identifier (teacher's electronic pen identifier), determines the type as “first type”, and “ The “first type” is arranged on the memory.

  Next, the teaching material element type determination means 1331 acquires the coordinate information “(xa, ya)” in the middle of the coordinate information group “(x1, y1) (x2, y2)... (Xn, yn)”. To do. Then, the learning material element type determination means 1331 reads the first learning material element information “(30, 45) (31, 45) (32, 45)...” From the learning material element information management table of FIG. . Next, the teaching material element type determining means 1331 includes the coordinate information group “(30, 45) (31, 45) (32, 45)... Then, it is determined whether or not the acquired coordinate information “(xa, ya)” is included. Here, “(xa, ya)” is assumed to be included in the coordinate information group “(30, 45) (31, 45) (32, 45).

  Then, the learning material element type determination unit 1331 acquires learning material element classification information “0” corresponding to the first learning material element information. The learning material element classification information “0” indicates that the learning material element information is first learning material element information.

  Next, the first teaching material element information acquisition unit 1332 is the distance closest to “(x1, y1)” of the acquired coordinate information “(x1, y1) (x2, y2)... (Xn, yn)”. Is obtained from the coordinate information group “(30, 45) (31, 45) (32, 45)...” Of “ID = 1” in the teaching material element information management table of FIG. Here, it is assumed that the first teaching material element information acquisition unit 1332 has acquired “(32, 45)”. Then, the first teaching material element information acquisition unit 1332 starts from the first coordinate information “(30, 45)” of the coordinate information group “(30, 45) (31, 45) (32, 45). , The three pieces of coordinate information “(30, 45) (31, 45) (32, 45)” up to the acquired coordinate information “(32, 45)” are stored in “ID = 1” in the teaching material element information management table of FIG. ”And add it to the memory.

  Then, the process of acquiring the coordinate information in the teaching material element information corresponding to each point of the acquired coordinate information “(x1, y1) (x2, y2)... (Xn, yn)” is performed using the point (xn, yn). ) Continue until. Then, it is assumed that the first teaching material element information acquisition unit 1332 obtains coordinate information “(30, 45) (31, 45) (32, 45). “(52, 45)” is “-” in the first stroke of the Chinese character “red”.

  Next, the first output means 1341 outputs a point or a line corresponding to the acquired coordinate information “(30, 45) (31, 45) (32, 45)... (52, 45)”. That is, the first output means 1341 uses “−” of the first stroke of the Chinese character “red” from the acquired coordinate information “(30, 45) (31, 45) (32, 45)... (52, 45)”.
