  The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a block diagram schematically showing the structure of the display device 101. The display device 101 includes an input receiving unit 110 and a display control unit 140.

  The input reception unit 110 receives input from the user. The user uses the input device provided in the input reception unit 110 to input input information such as characters and figures into the input reception unit 110. In addition, the user inputs an instruction to the display device 101 using an input device provided in the input receiving unit 110.

  As an input device disposed in the input receiving unit 110, a keyboard, a mouse, a trackball, a trackpad, a pen tablet, a voice input device, a gesture detection device, or the like can be used. Further, the entire surface or a part of the individual display unit 121 may be used as a touch panel and used as the input receiving unit 110.

  The display control unit 140 includes an individual image output unit 120 and a public image output unit 130 as a first output unit and a second output unit. The individual image output unit 120 causes the individual display unit 121 to display an individual image. The individual display unit 121 is individually displayed for a user who inputs information or an instruction to the input receiving unit 110.

  The public image output unit 130 displays at least a part of the individual image displayed on the individual display unit 121 by the individual image output unit 120 in the public image display area 134 of the public display unit 131. The public display unit 131 displays a public image toward a person other than the user.

  The individual display unit 121 and the public display unit 131 can be formed using an LCD, a CRT, a plasma display, or the like, respectively. The individual display unit 121 and the public display unit 131 may be a direct view display device or a projection display device. Furthermore, the individual display unit 121 and the public display unit 131 may be formed by different devices. The individual display unit 121 and the public display unit 131 may have different sizes.

  FIG. 2 is a schematic diagram illustrating an example of a usage pattern of the display device 101. The display device 101 is used, for example, in a classroom where one lecturer and a plurality of students are present.

  The input reception unit 110 is arranged near the lecturer and is exclusively operated by the lecturer. The instructor inputs display information or a material thereof to the display device 101 by operating the input receiving unit 110. The instructor also inputs an instruction regarding the operation of the display device 101 from the input receiving unit 110.

  The individual display unit 121 is arranged near the lecturer and displays an image toward the lecturer. The individual image output unit 120 generates a display image to be displayed on the individual display unit 121 based on the display content input by the lecturer and the display content edited or processed by the instruction of the lecturer.

  Of the display images displayed by the individual image output unit 120 on the individual display unit 121, the public image output unit 130 displays a display image instructed by the lecturer to be displayed toward the student. It is displayed in the display area 134. For this reason, the display content of the public display unit 131 includes a part of the display content of the individual display unit 121. The display content of the public display unit 131 is observed by all students.

  When using the display device 101, the lecturer first operates the input receiving unit 110 to input input information such as characters and images to the display control unit 140. The input receiving unit 110 receives input information directly input by the instructor through operation of a keyboard, a tablet, a mouse, or the like, or may use information selected from prestored information as input information. The information stored in advance may be prepared by an instructor or may be transferred from an external library or the like.

  The input reception unit 110 transmits the individual image generated based on the input information received from the lecturer to the individual image output unit 120 and causes the individual display unit 121 to display the individual image. Thereby, the lecturer can confirm whether the input information is input to the display control unit 140 or how the input information looks.

  Next, the instructor operates the input reception unit 110 to instruct editing, processing, selection, and the like of the input information. The individual image output unit 120 deforms the image to be displayed on the individual display unit 121 according to the instruction received through the input reception unit 110. Thereby, the lecturer can confirm that the instruction input to the input receiving unit 110 is reflected in the individual display image.

  Further, the instructor operates the input receiving unit 110 to instruct the public display unit 131 to display the individual image. When the display control unit 140 receives an instruction to publish an image from the input receiving unit 110, the display control unit 140 transmits the image input and processed in the individual image output unit 120 to the published image output unit 130. The public image output unit 130 causes the public display unit 131 to display the acquired public image.

  With respect to the individual display unit 121 arranged in the vicinity of the lecturer, the public display unit 131 is arranged at a position that can be seen by all the students. Therefore, the public image displayed on the public display unit 131 is observed by all the students. In this way, the display device 101 can edit or process characters, images, and the like input by the instructor without showing them to the student, and can display the completed image to the student.

  When the display device 101 as described above is used, the instructor can display input information on the public display unit 131 while operating the input receiving unit 110 toward the individual display unit 121 different from the public display unit 131. it can. Information input in the input reception unit 110 may be performed by directly inputting display contents each time, or may be displayed by calling a file prepared in advance.

  FIG. 3 is a schematic view illustrating the display contents of the individual display unit 121 and the public display unit 131 in the display device 101. In FIG. 3, the same reference numerals are assigned to elements common to FIG. 1, and redundant description is omitted.

  The individual display unit 121 of the individual image output unit 120 displays a directory display area 122, a monitor image display area 124, an icon display area 126, a memo display area 128, an input process display area 129, and the like.

  The directory display area 122 displays a list of files stored in the display device 101 together with the directory. The monitor image display area 124 displays the display content displayed on the public display unit 131 in a reduced state.

  The icon display area 126 displays a plurality of operation icons 127. The operation icon 127 serves as an interface for instructing the operation of the display device 101 itself. The operation icon 127 also serves as an interface for processing or editing information input to the display device 101.

  In the memo display area 128, an image that the instructor refers but does not show to the student is displayed. In addition, the instructor can add or delete information in the memo display area 128 without displaying it in the public display unit 131.

  In the input process display area 129, information input by the instructor from the input receiving unit 110 is temporarily displayed. The input information displayed in the input process display area 129 displays an image whose state is not fixed, such as handwritten input before shaping, kana characters before kana-kanji conversion, or the like. In other words, the instructor performs an input operation while looking at the input process display area 129, and instructs shaping, conversion, and the like of input information. Note that the input receiving unit 110 may also execute spell check, grammar check, and the like of input information in the course of the above input operation.

  In the individual display section 121, the directory display area 122, the monitor image display area 124, and the icon display area 126 are displayed by dividing the display area of the individual display section 121 from each other. On the other hand, the memo display area 128 and the input process display area 129 are displayed as a floating window so as to overlap the monitor image display area 124.

  As a result, the monitor image display area 124 for displaying an annotation or the like can be displayed near the display to be annotated. In addition, the input process display area 129 can be displayed in the vicinity of the final display position to reduce the movement of the teacher's line of sight. Of course, the display method of each display area is not limited to the illustrated form.

  Note that each of the directory display area 122, the monitor image display area 124, the icon display area 126, the memo display area 128, and the input process display area 129 has a scroll bar 123. Thereby, each display area can display more contents than can be displayed in a physical area. Further, the distribution and display position in the individual display unit 121 of each display area may be changed.

  Further, it may be possible to select not to display a part of the display area. That is, when the content input to the input receiving unit 110 is displayed on the public image output unit 130 without being edited, the icon display area 126 may be hidden. Further, when an existing file is not called, the directory display area 122 may be hidden. Further, when the input operation is not performed, the input process display area 129 may be hidden. Thereby, the effective display area of the individual display part 121 can be expanded.

  The display content displayed in the monitor image display area 124 in the individual image output unit 120 as described above is displayed on the public display unit 131 by the instruction of the lecturer or automatically. However, the display contents of the directory display area 122, icon display area 126, memo display area 128, and input process display area 129 are not displayed on the public display unit 131.

  As described above, in the display device 101, the individual image output from the individual image output unit 120 and displayed on the individual display unit 121 and the public image output from the public image output unit 130 and displayed on the public display unit 131 are mutually connected. Is different.

  However, the individual image displayed on the individual display unit 121 includes all the contents of the public image displayed on the public display unit 131. In other words, the individual image output by the individual image output unit 120 is obtained by adding a unique image that is not displayed on the public display unit 131 such as a memo, an operation icon, and an editing process to the public image output by the public image output unit 130. Is formed.

  FIG. 4 is a schematic diagram illustrating a process in which the graphic input by the lecturer is displayed on the individual display unit 121 and the public display unit 131 on the display device 101. FIG. 4 shows a process in which a part of the individual display unit 121 having a touch panel function is used as the input receiving unit 110 and a graphic input by the instructor by handwriting input is shaped and displayed on the public display unit 131.

  First, an image in which characters and figures are mixed is input by handwriting input to the input receiving unit 110. As a result, for example, as shown in the figure with reference numeral A, when the tablet of the input receiving unit 110 is operated, the input locus by the instructor's handwriting is immediately displayed in the input process display area 129 of the individual display unit 121. Is displayed.

  Next, by selecting the operation icon 127 in the icon display area 126, the input receiving unit 110 receives an instruction to shape the input image. In the illustrated example, an operation icon 127 indicating an instruction such as “shape shaping”, “all shaping”, “shape shaping”, or the like is prepared as an instruction regarding “shaping”.

  The instructor can shape part or all of the input image by selecting one of these operation icons 127. The result of shaping the input image is displayed in the input process display area 129 of the individual display unit 121 as indicated by reference characters B, C, and D in the figure.

  Subsequently, an instruction of “public display” by the lecturer is input to the icon display area 126. As a result, the shaped figure and characters are displayed in the monitor image display area 124 of the individual display unit 121.

  Further, as shown in the figure by the symbol E, the shaped image is also displayed on the public display unit 131. In this way, the student can see the graphic input by the instructor on the public display unit 131 in a shaped state.

  In the icon display area 126, an operation icon 127 for instructing editing or deletion of an image once input may be further mounted and displayed after further processing the input image. Further, even the display content displayed on the public display unit 131 may be edited again when the instructor instructs. In such a case, the editing process may be hidden from the student and the display content after confirmation may be displayed on the public display unit 131.

  Further, in preparation for re-editing from the stage immediately after handwriting input, an image before shaping immediately after handwriting input may be continuously displayed after shaping. Further, the display control unit 140 may sequentially store images in the editing process in addition to the images before shaping in time series. Thereby, the input operation can be performed again from the shaping or recognition stage. Also in such a case, when the lecturer desires to display, the public image output unit 130 may display a shaping process, a conversion process, and the like in the re-editing.

  As described above, it is left to the instructor to determine whether to display what is displayed on the individual display unit 121 on the public display unit 131. However, the public image output unit 130 automatically restricts the display on the public display unit 131 for restrictions that are known in advance, such as limiting the display of unlearned kanji and terms, for example. May be.

  FIG. 5 is a diagram illustrating an example of a display process when the image showing the input process in FIG. 4 is displayed in the public image display area 134 of the public display unit 131. When displaying an image on the public display unit 131, the public image output unit 130 may display the image step by step, as indicated by reference characters P to Z in the figure.

  Thereby, the image in the public display part 131 can be shown to a student with the process in which the whole image is formed. In addition, the display speed in the public display unit 131 can be reduced to the same level as the speed at which the student takes notes, for example. Therefore, the student can deepen the understanding of the course contents by reading and writing the contents displayed on the public display unit 131 while following the process leading to the conclusion.

  Instructions such as “unshaped” used when intentionally maintaining the shape of handwritten input and “no conversion” used when displaying kana characters without converting them into kanji are implemented in the input receiving unit 110. May be. Thereby, it is possible to achieve both a delicate expression by handwriting and good visibility by the shaped character. In addition, when a Japanese sentence is included in the input image, a kana-kanji conversion operation may be added.

  Further, the input receiving unit 110 is instructed to add an underline, an enclosure, a blinking cursor mark, and the like for the purpose of partial emphasis on the public image already displayed on the public display unit 131. May be implemented. Still further, instructors' expression methods such as an instruction to enlarge or reduce a part or the whole of the public image displayed on the public display unit 131, an instruction to hide a part of the public image, an instruction to cut off a part of the public image, etc. Different instructions may be implemented together.

  FIG. 6 is a schematic diagram illustrating a process of displaying characters input by the lecturer on the individual display unit 121 and the public display unit 131. FIG. 6 shows a process in which a part of the individual display unit 121 having a touch panel function is used as the input receiving unit 110, and the character input by the instructor by handwriting input is shaped and converted and displayed on the public display unit 131.

  First, kana characters are input by handwriting input to the input receiving unit 110. As a result, as shown in the figure by reference symbol A, the input locus by the instructor's handwriting is immediately displayed in the input process display area 129 of the individual display unit 121.

  Next, at the boundary of the input character string, for example, at the boundary of a word, a phrase, etc., an instruction of “shaping” is made in the icon display area 126 forming the input receiving unit 110 by a gesture, key, button, icon, etc. Entered. As a result, as shown in the drawing by reference numeral B, the input process display area 129 displays a character string that has been shaped in a predesignated typeface. In addition, in the input reception part 110, you may enable it to select the display formats of characters, such as an underline, bold type, and italic type, besides a typeface.

  Subsequently, an instruction of “conversion” by the lecturer is input to the icon display area 126. As a result, a character string converted into Kanji in a font designated in advance is displayed in the input process display area 129 as shown in the figure by reference C.

  Next, an instruction of “display” by the lecturer is input to the icon display area 126. As a result, as shown in the figure by reference D, a character string expressed in Chinese characters in the designated font is displayed in the monitor image display area 124 in the individual display unit 121.

  In addition, the character string is displayed in Kanji notation in the designated font on the public display unit 131 as indicated by the symbol E in the drawing. In this way, the student can view the character string input to the input receiving unit 110 by the instructor on the public display unit 131 in a state of being shaped and converted.

  Note that an input buffer may be provided in the input receiving unit 110 so that input loss is prevented when the input speed on the instructor side exceeds the display speed. Further, in the input receiving unit 110, part of instruction inputs such as “shaping”, “conversion”, “display”, etc. may be automated to reduce the instructor's effort related to the instruction input.

  Moreover, even if it is the display content once displayed on the public display part 131, when the lecturer directs, the displayed display content may be edited again. In such a case, the editing process may be hidden from the student and the display content after confirmation may be displayed on the public display unit 131.

  Furthermore, an image before shaping immediately after handwriting input may be stored in the display control unit 140 after shaping in preparation for re-editing from the stage immediately after handwriting input. Thereby, the input operation can be performed again from the shaping or recognition stage. Also in such a case, when the lecturer desires to display, the public image output unit 130 may display a shaping process, a conversion process, and the like in the re-editing.

  As described above, it is left to the instructor to determine whether to display what is displayed on the individual display unit 121 on the public display unit 131. However, the public image output unit 130 automatically restricts the display on the public display unit 131 for restrictions that are known in advance, such as limiting the display of unlearned kanji and terms, for example. May be.

  FIG. 7 is a diagram illustrating an example of a display process when the character string indicating the input process in FIG. 6 is displayed in the public image display area 134 of the public display unit 131. When displaying a character string on the public display unit 131, the public image output unit 130 sets 1 for each of the characters forming the character string to be displayed in accordance with the stroke order of the character, as shown in FIG. The images may be displayed sequentially.

  Thereby, the display speed of the public display unit 131 can be reduced to the same level as the speed at which the student takes notes, for example. Therefore, the student can deepen the understanding of the course contents by reading and writing the contents displayed on the public display unit 131 while following the process leading to the conclusion.

  Instructions such as “unshaped” used when intentionally maintaining the shape of handwritten input and “no conversion” used when displaying kana characters without converting them into kanji are implemented in the input receiving unit 110. May be. Thereby, it is possible to achieve both a delicate expression by handwriting and good visibility by the shaped character. When a keyboard or the like is used for the character string for the input receiving unit 110, the steps up to the shaping instruction are omitted, and the input procedure is executed from the step indicated by the symbol B in FIG.

  In addition, the public display unit 131 notifies the student of the stroke order of the display characters together with the display contents. Therefore, in the training in the primary education, the display device 101 can automatically satisfy the educational guidance for the board writing.

  If it is determined that the input speed to the input receiving unit 110 by the lecturer exceeds the speed understood by the student or the writing speed, the display control unit 140 issues a warning to that effect through the individual image output unit 120. You may display on the display part 121. FIG. Thereby, even a lecturer who is not skilled in the course can carry out a highly effective course.

  As described above, the display device 101 has a function of controlling the display speed and the display method as well as displaying the display content as it is. Thereby, while reducing the burden of the lecturer who inputs a public image, the efficiency of the information transmission by a class and the depth of understanding can be improved.

  FIG. 8 is a block diagram of the display device 102. The display device 102 has the same structure as the display device 101 shown in FIG. Therefore, common elements are denoted by the same reference numerals, and redundant description is omitted.

  The display device 102 includes a communication line 152 and an imaging unit 154 connected to the input reception unit 110. Thereby, the input receiving unit 110 can acquire input information from the server 153 through the communication line 152. In addition, a lecturer who operates the input receiving unit 110 can refer to external information during the course without displaying it on the public image output unit 130. The communication line 152 may be a LAN, the Internet, a dedicated line, or the like, but is not limited thereto.

  Note that in the display device 102, the input receiving unit 110 also receives an instruction of an instructor regarding access to the communication line 152. That is, the input receiving unit 110 receives establishment and blocking of communication with the communication line 152, designation of a connection destination, designation of acquired information, and the like.

  Further, the input receiving unit 110 can capture an image such as an existing printed matter or a written matter through the imaging unit 154. In the display device 102, the input receiving unit 110 also receives an instruction from the lecturer regarding the operation of the imaging unit 154. In other words, the input reception unit 110 receives instructions regarding the imaging unit 154, for example, designation of an imaging target and an imaging range, and enlargement, reduction, and clipping of a captured image.

  As described above, by providing the input receiving unit 110 with a peripheral device that assists in obtaining the display information, a part of the trouble of obtaining and creating the display information can be saved. Also, information that changes constantly, such as weather and currency exchange, can be acquired and input in the latest state.

  FIG. 9 is a block diagram of the display device 103. The display device 103 has the same structure as the display device 101 shown in FIG. Therefore, common elements are denoted by the same reference numerals, and redundant description is omitted.

  In the display device 103, the display control unit 140 includes an individual image recording unit 142 and a public image recording unit 144. The individual image recording unit 142 records an individual image output from the individual image output unit 120 toward the individual display unit 121. By recording the individual images in this manner, it is possible to reproduce the input process to the display control unit 140 of the lecturer during the course time. As a result, it is possible to examine how to proceed with the training later and to improve the training technology.

  Also, the public image recording unit 144 records a public image output from the public image output unit 130 toward the public display unit 131. By recording the public image in this way, it is possible to reproduce the class from the viewpoint of the student. Therefore, it is possible to provide classes for absentees, reproduce classes through recording media, and the like.

  Further, the display device 103 may include a recording unit 146 and an imaging unit 148 connected to the input receiving unit 110. Thereby, the question and answer which a lecturer does not input into the input reception part 110, the mode of exercise, etc. can be recorded. This makes it possible to create a more detailed record of the course and to manage attendance by individual authentication of the student.

  FIG. 10 is a block diagram of another display device 104. The display device 104 has the same structure as the display device 101 shown in FIG. Therefore, common elements are denoted by the same reference numerals, and redundant description is omitted.

  The display device 104 includes a sub input receiving unit 112 in addition to the input receiving unit 110. The sub input receiving unit 112 is coupled to the individual image output unit 120 by wire or wireless. Thereby, in addition to the input receiving unit 110, information from the sub input receiving unit 112 can be input to the individual image output unit 120. Therefore, for example, one of the students can operate the auxiliary input receiving unit 112 and input information to the individual image output unit 120.

  Information input from the sub input receiving unit 112 is first displayed on the individual display unit 121 through the individual image output unit 120. The information displayed on the individual display unit 121 is displayed on the public display unit 131 according to the instruction of the lecturer input from the input receiving unit 110. In other words, when the instructor does not instruct to display, the content input from the sub input receiving unit 112 is not displayed on the public display unit 131.

  Thus, the sub input receiving unit 112 has the same function as the input receiving unit 110 in that information can be input. However, an instruction as to whether or not the received input is reflected on the display of the public display unit 131 is left to a lecturer who operates the input reception unit 110. By using such a function, it is possible to present the exercises, questions, etc. by the students to all the participants in the class and advance the class. Note that the auxiliary input receiving unit 112 may be reused by a plurality of students, or may be prepared in advance for the number of students.

  In the above example, a seminar is given as an example, but the use of the display device 101 is not limited to a lecture, a lecture, and the like. For example, the operator of the input reception unit 110 can be used as a class transmission device in a conference while using the display device 101. However, the display device 101 can be configured differently for a meeting or the like in which a plurality of speakers participate.

  FIG. 11 is a schematic diagram showing another display device 105 according to usage patterns. The display device 105 is used in a conference with a plurality of participants. The display device 105 includes a public display unit 131, a display control unit 140, and an individual device 160.

  One individual device 160 is assigned to each conference participant. Each of the individual devices 160 includes an input receiving unit 110 and an individual display unit 121 together.
