However, any device can be used as long as the terminal device 200 can be operated and the play can input characters, numbers, and the like. For example, a keyboard, mouse, touch pad, or the like may be used.

  The touch panel includes a substantially rectangular detection surface having a shape and size corresponding to the screen of the display unit 234. When an object comes in contact with the detection surface, the touch position of the object is detected. In the present embodiment, the touch panel sequentially detects the contact position of the object at a predetermined time interval. The detection surface of the touch panel is arranged so as to overlap the screen of the display unit 234. In addition, the touch panel does not necessarily detect the position of the object only when the object touches the detection surface, but detects the position of the object with respect to the detection surface when the object is close to the detectable range on the detection surface. You may do it. The touch panel may be of any type as long as it is a device that can detect the position of an object on the detection surface, such as a capacitance type, a pressure-sensitive type, or an optical type.

  The learner performs operation input by bringing an object such as his / her finger or stylus (pen-type device) into contact with the touch panel. When the operation unit 233 is operated by the learner, the operation unit 233 generates a signal corresponding to the operation and supplies the signal to the terminal processing unit 235.

  The terminal processing unit 235 includes at least a browsing execution unit 2351 and a handwritten character display unit 2352 as functional modules that are realized by the various programs described above or are implemented in the terminal device 200 as firmware.

  The browsing execution unit 2351 acquires and displays display data related to the progress of learning described above. That is, the browsing execution unit 2351 transmits a display data acquisition request related to learning, such as a model image and various screens, to the server device 100 via the terminal communication unit 231 in accordance with an instruction from the learner, Corresponding display data is received from the server device 100 via the terminal communication unit 231. Furthermore, the browsing execution unit 2351 creates drawing data based on the received display data. That is, the browsing execution unit 2351 analyzes the received display data, specifies the control data and the content data, and reconstructs the drawing data by laying out the content data specified in accordance with the specified control data. The drawing data is output to the display unit 234.

Data is output to the display unit 234.

  More specifically, the browsing execution unit 2351 functions as a model display unit, a handwriting area display unit, a handwritten character display unit, and a deviation presentation unit. The model display unit displays a model image of the character on the display unit 234 for the character to be written by the learner. The model display means can read the model image temporarily stored in the terminal storage unit 232 from the terminal storage unit 233 and display it. The handwriting area display means displays a handwriting area, which is an area for the learner to write characters, on the display unit 234. The deviation presenting means visually presents the deviation between the handwritten image and the model image to the learner by continuously changing at least one of the shape and the position of the handwritten image on the display unit 234. For example, the deviation presentation unit can superimpose and display the intermediate image model image from the handwritten image generated by morphing to the model image. Details of these functions of the browsing execution unit 2351 will be described later.

  The handwritten character display unit 2352 displays a handwritten image written by the learner in the handwriting area. For example, when the display unit 234 is a touch screen display, the handwritten character display unit 2352 detects an object such as a user's finger or stylus on or near the touch screen display, and a position or movement of the detected finger or stylus or the like. The handwritten image written in the area by the learner is drawn in the handwriting area in accordance with the locus. Also, depending on the setting, when the touch panel is touched with a stylus pen or the like, a check mark can be written or a predetermined illustration image can be inserted at the touch position instead of drawing a line.

  In the learning support system 1 configured as described above, a preferred embodiment of the learning support process executed in accordance with the learning support program according to the present invention will be described below.

  FIG. 5 is a schematic flowchart showing a part of the processing procedure executed by the embodiment of the present invention. Here, a case will be described in which a learner learns how to write hiragana characters “ho” using a stylus on a tablet terminal (terminal device 200). As shown in the figure, when the learner turns on the tablet terminal, the home screen is displayed on the display unit 234 of the tablet terminal (S51). For example, the home screen may display the progress of learning so far, the target of this month, and the like.

  Next, when the learner taps the learning start button displayed on the display unit 234 to instruct the start of learning, the learning start instruction data is transmitted from the tablet terminal to the server apparatus 100 together with the learner ID. (S52).

  When the server device 100 receives the learning start instruction data, the server device 100 searches the learner master from the received learner ID and refers to the learner's learning history. And the learner's learned handwritten image is acquired and a character table screen presentation process is performed. FIG. 6 shows an example of a character table screen. The character table displays a list of characters that can be learned. In the example of FIG. 6, hiragana with 50 sounds is displayed in a list, and it is possible to switch to a list of katakana by pressing the katakana button. The subject of writing learning is not limited to hiragana and katakana, but may be kanji, hangul, alphabet, numbers, figures, symbols, and the like. It is also possible to practice painting. Preferably, in the list of characters in the character table, a learner's handwritten image is displayed in the learned character column, and a model image is displayed in the unlearned character column.

  When the learner taps and selects a character to learn from the character table, the character ID is transmitted from the tablet terminal to the server device 100. When the server device 100 receives the character ID, the screen presentation processing unit 1331 preferably searches for a model master from the received character ID, and performs a learning screen presentation process including a model image (S53). Data relating to the model image and the learning screen is transmitted from the server device 100 to the tablet terminal (S54). When the tablet terminal receives the model image, the terminal storage unit 232 stores the received model image at least temporarily. The model image stored in the terminal storage unit 232 is read by the browsing execution unit 2351 and displayed on the learning screen.

  FIG. 7 is a diagram illustrating an example of a learning screen according to the present embodiment. The learning screen is displayed by the browsing execution unit 2351. The learning screen includes a handwriting area 301 in which a learner can write a character, and a model display area 302 in which a character writing model image is displayed. In this example, the handwriting area 301 and the model display area 302 are displayed side by side, and the learner uses the stylus to write the character “ho” in the handwriting area 301 while viewing the model image 402 of “ho”. Can be handwritten. When the learner brings the stylus into contact with or close to the operation unit 233 of the tablet terminal, the handwritten character display unit 2352 detects the stylus. According to the detected stylus position or movement trajectory, the handwritten character display unit 2352 displays the handwritten character in the handwritten area 301 (S55).

  When the handwritten character display unit 2352 determines that the character has been written by the learner, the handwritten image is at least temporarily stored in the terminal storage unit 232 and transmitted to the server device 100 (S56). When the server apparatus 100 receives the handwritten image 401, the intermediate image generating unit 1332 generates an image (intermediate image) whose shape is changing from the handwritten image 401 to the model image 402 (S57).

  Specifically, the intermediate image generation unit 1332 uses the movement trajectory of the stylus (hereinafter referred to as stroke data) when the learner performs writing and the model stroke data stored in the server storage unit 132 in advance. To generate an intermediate image. Specifically, the stroke data is treated as time-series continuous feature points (coordinates), and correspondence is given to the stroke data of the model and the stroke data of the learner based on the elapsed time and distance from the writing. Based on this correspondence, the intermediate image generation unit 1332 generates an intermediate image so that each feature point of the stroke data of the handwritten image gradually approaches the feature point of the stroke data of the model. For this intermediate image generation processing, existing techniques such as morphing and cross dissolve can be used.

  By making the interval at which the intermediate image is generated fine, it becomes possible to change smoothly. The generated intermediate images are arranged in time series in the order of change, and transmitted to the tablet terminal (S58). At this time, the received handwritten image 401 and the generated intermediate image are registered in the learning master (S59).

  On the other hand, when the writing of the learner's characters is completed, the tablet terminal displays the handwritten image 401 written in the handwriting area 301 and the model image 402 so as to be superimposed (S60). For example, a model image may be superimposed and displayed on a handwritten image, such as a model image 403 shown in FIG. The model image 403 is displayed in a well-balanced position with a well-balanced size with respect to the handwriting area.

  When the tablet terminal receives the intermediate image from the server device 100, the browsing execution unit 2351 continuously changes the shape and position of the handwritten image, so that the user can visually recognize the difference between the handwritten image and the model image. Present (S61). Specifically, a plurality of intermediate images that interpolate the pixel difference between the handwritten image 401 superimposed on the handwriting area 301 and the model image 403 are displayed in the order of display of the plurality of intermediate images. Displayed sequentially in the handwriting area 301 so as to be in chronological order following the change in shape. Thereby, the shape of the handwritten image 401 can be displayed as if it gradually changed to the shape of the model image 403.

  On the learning screen, a slide bar is displayed as an interface that allows the user to adjust the degree of change when continuously changing at least one of the shape and position of the image of the handwritten character in the browsing execution unit 2351. Yes. The display unit 234 of the tablet terminal 200 switches the intermediate image to be displayed according to the direction or speed of the operation from the learner with respect to the slider of the slide bar. More specifically, the terminal processing unit 235 determines an intermediate image to be displayed on the display unit 234 according to the position of the slider, and determines a speed for switching the intermediate image according to a speed at which the learner moves the slider. be able to. For example, in the example of FIG. 8, when the learner moves the slider 501 of the slide bar 500 from right to left, the handwritten image gradually changes to a model image.

  FIG. 9 is a diagram schematically showing the state of this change. 9A is an image (handwritten image) displayed when the slider 501 is at the position 601 that is the position of the right end of the slide bar 500 in FIG. FIG. 9B shows an intermediate image displayed when the slider 501 is at the position 602, and FIG. 9C shows an intermediate image displayed when the slider 501 is at the position 603. . FIG. 9D shows an image (example image) displayed when the slider 501 is at the position 604 that is the position of the left end of the slide bar 500. In this way, as the slider 501 is moved from right to left, the handwritten image gradually changes from (A) to (D) in FIG. 9 so as to approach the model image.

  On the other hand, when the slider 501 of the slide bar 500 is moved from the left to the right in FIG. 8, the shape can be changed from (D) to (A) in FIG. Furthermore, the speed of change may be controlled according to the speed at which the slider 501 is moved. As described above, the slide bar 500 can control the direction or speed of change in the shape of the handwritten image 401 in accordance with an operation from the learner.

  This allows the learner to intuitively recognize what shape should be corrected because the difference between the model image displayed as a model and the handwritten image that is the character he / she wrote can be seen at a glance. Can do.

[Other Embodiments]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.

  For example, in the above-described embodiment, the tablet terminal is configured to communicate with the server apparatus 100 and transmit / receive data necessary for writing learning. However, the present invention is not limited to this. For example, the tablet terminal downloads data necessary for writing learning from the server apparatus 100 as a writing learning application, and does not communicate with the server apparatus 100 when the writing learning application is executed. Also good.

  In the above-described embodiment, the configuration for changing the shape of the handwritten image has been described. However, as shown in FIG. 10, the model display area 302 and the handwritten area 301 are displayed side by side, and the slider 501 of the slide bar 500 is displayed. It is good also as a structure which superimposes a sample image and a handwritten image according to a motion. For example, when the slider 501 in FIG. 10 is dragged to the left, the handwritten image 401 moves to the left of the screen together with the handwritten area 301 ((A) in FIG. 10). At this time, for example, when the slider 501 is not on the rightmost side, the handwritten image 401 can be displayed in an easy-to-view manner when the handwritten image 401 is superimposed, for example, by reducing the color of the model image 402. When the slider 501 moves to the leftmost position, the model display area 302 and the handwriting area 301 overlap each other, and a deviation between the model image 402 and the handwritten image 401 can be confirmed.

  In the above-described embodiment, when the learner performs the writing method learning using FIG. 7, the character writing is performed while looking at the model image 402 in the model display area 302 displayed side by side with the handwriting area 301. However, the model display area may not be displayed on the learning screen. In this case, the model image is not displayed on the learning screen until the learner's character has been written and the model image 403 is displayed in the handwriting area.

  In addition, although the slide bar has been described as an interface for switching the intermediate image, the present invention is not limited to this, and for example, a button or the like on which left and right arrows are displayed may be used. In this case, the display unit 234 can switch the intermediate image according to the number of times the learner has pressed the button.

  Further, in the above-described embodiment, the configuration in which the intermediate image is generated in the server device 100 has been described.
