  The techniques described in Patent Document 1 and Patent Document 2 can highlight a predetermined part of a sentence according to a user's operation. For example, even when reading another part, the highlighting is performed. There is a problem that it is not possible to concentrate on the part to be read because the done part remains as it is. In general, when all the characters on a page are displayed at the same time, it is difficult to feel the inflection of a sentence caused by the speed at which words are read.

  On the other hand, as described in Patent Document 3, when the text is read out by voice, it is impossible to match the speed of individual reading of the user, and further, the part where the user wants to read can be advanced or returned to the front. It is difficult to read.

  Moreover, in the subtitle display as described in Patent Document 4, since the text is displayed by dividing it by one line or several lines at a time, it is possible to concentrate on only the information of the displayed line. Since the display contents are arbitrarily switched at time intervals, it is impossible to meet the user's demand for reading speed and reading specific portions slowly.

  In view of such problems, the object of the present invention is to respond to the user's natural reading speed and reading catch (request to read a specific part slowly) and to concentrate only on the part where the user is reading. An object of the present invention is to provide a document display device and a document display method that can be used.

  According to the invention of claim 1, the document display device includes an image display unit having a display screen, a document input unit to which a document is input, an analysis unit input unit to which an analysis unit is input, and an input from the document input unit. Set the display position on the display screen for each sentence element of the document analyzed by the analysis unit, and the analysis unit that analyzes the analyzed document with the sentence element input as the analysis unit from the analysis unit input unit. And a position setting storage unit that stores document image data, a finger position detection unit that is disposed on the display screen and detects a finger touch position, and a display control unit, the display control unit is a position setting storage unit When the document is displayed on the display screen with low contrast based on the image data of the document stored in the screen and the finger position detection unit detects the touch position of the finger, the presence or absence of a sentence element at the display position corresponding to the touch position Search the position setting storage unit to determine , If there is text elements of a display position corresponding to the touch position, to emphasize the contrast of the sentence elements, after a predetermined time has elapsed, is intended to perform the highlight display control to return to the original weak contrast.

  In the invention of claim 2, in the invention of claim 1, when the touch position is at the end of the line and the sentence element at the display position corresponding to the touch position does not extend over the next line, the display control unit starts the next line. At the same time, the sentence element is controlled to be highlighted.

  In the invention of claim 3, in the invention of claim 1, when the touch position is the beginning of a line and the sentence element of the display position corresponding to the touch position starts from the beginning of the line, the display control unit Increase the time to restore the original weak contrast of the sentence element.

  In the invention of claim 4, in the invention of claim 1, the finger position detector detects the touch position of the finger at predetermined time intervals, the touch position does not change, and the sentence element of the display position corresponding to the touch position is detected. If it exists, the display control unit continues the contrast enhancement display of the sentence element.

  According to the invention of claim 5, the document display method includes a document input process in which a document is input, an analysis unit input process in which an analysis unit is input, and an analysis in which the document is analyzed with a sentence element input as an analysis unit. A position setting storage process for setting a display position for each sentence element of the analyzed document on the display screen of the image display unit, and storing the position and image data of the document in the position setting storage unit; , A process of displaying a document on a display screen with weak contrast based on image data of the document, a finger position detection process of detecting a finger touch position by a finger position detection unit arranged on the display screen, and a finger touch position Is detected by searching the position setting storage unit for the presence or absence of the sentence element at the display position corresponding to the touch position. If there is a sentence element at the display position corresponding to the touch position, the contrast of the sentence element is detected. Emphasize After the constant time, and a process of performing emphasis display control to return to the original weak contrast.

  In the invention of claim 6, in the invention of claim 5, when the touch position is the end of the line and the sentence element at the display position corresponding to the touch position does not extend over the next line, the sentence element at the beginning of the next line is also At the same time, highlighting control is performed.

  In the invention of claim 7, in the invention of claim 5, when the touch position is the beginning of a line and the sentence element of the display position corresponding to the touch position starts from the beginning of the line, the element of the sentence element at the end of the previous line Increase the time to return to low contrast.

  In the invention of claim 8, in the invention of claim 5, when the touch position of the finger is detected at a predetermined time interval, the touch position does not change, and there is a sentence element of the display position corresponding to the touch position. Contrast highlighting of the sentence element is continued.

  According to this invention, according to the user's natural reading speed and reading catch (request to read a specific part slowly), only the part that the user is paying attention to can be displayed with the contrast enhanced. The user can concentrate on the part he / she wants to read and speak the sentences that are highlighted in order, for each sentence group, ie for each sentence element (for example, for each character, word, phrase, sentence). It is possible to understand as if you were listening to the words.

  The whole document is not displayed in contrast-enhanced form, but the entire document is displayed in low contrast in advance. Only the point of interest is displayed in contrast-enhanced form, which motivates people to continue reading. Can be provided. Unlike the underline of a highlighter pen or the like, the appearance of characters in the present invention becomes weaker in contrast over time. As a result, the user can concentrate on the place he / she wants to read without being distracted, and the sentences are processed in memory one after another and are also conscious during that time, so they are likely to remain in memory. Also, compared to text that is displayed line by line regardless of the recognition unit, such as a telop, the present invention makes it easy to understand the sentence because the sentence is clearly visible or almost invisible in the recognition unit of the sentence. Become.

  Pointing is one of the most natural ways to specify the target and place to draw attention, and the action of tracing the part that you read with your finger during reading can also be performed naturally on printed matter. In the present invention, such a natural operation is used as an index for detecting a portion that the user wants to read and its speed. This reduces user stress.

  Reading a sentence with your own active action of moving your finger is not only because the place where you read and the fingertips are spatially aligned, but it is not easy to turn your attention, but to understand the sentence with a rhythm There is an optimal rhythm, and it will be realized through its own body.

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

  FIG. 1 shows a functional configuration of an embodiment of a document display apparatus according to the present invention. The document display apparatus includes a document input unit 11, an analysis unit input unit 12, a display mode input unit 13, an analysis unit 14, and a position setting. A storage unit 15, an image display unit 16, a finger position detection unit 17, a display control unit 18, and a time measurement unit 19 are provided, and further, in this example, a vibration presentation unit 21 and a voice presentation unit 22 are provided.

  The image display unit 16 includes a display having a screen for displaying characters.

  A document is input from the document input unit 11. The document is, for example, an electronic book acquired using a network or the like, and the input document is sent to the analysis unit 14. Note that the document may be input from a keyboard, for example.

  A unit for analyzing a document is input from the analysis unit input unit 12. The analysis unit is a character, a word, a clause, and a sentence, and one of these is input as an analysis unit. Here, these characters, words, clauses, and sentences are referred to as sentence elements. The input sentence element is sent to the analysis unit 14.

  The analysis unit 14 analyzes the document input from the document input unit 11 with the sentence element input from the analysis unit input unit 12 as an analysis unit.

  The position setting storage unit 15 sets the display position on the display screen of the image display unit 16 for each sentence element of the document analyzed by the analysis unit 14, and displays the display position of each sentence element and the image data of the document. Remember. In this example, a display flag is associated with each sentence element of the document stored in the position setting storage unit 15, and the initial value of the display flag is OFF.

  The finger position detection unit 17 detects the user's finger position (finger touch position) on the display screen of the image display unit 16 at predetermined time intervals. The finger position detection unit 17 is configured by a touch panel or the like, and is disposed on the display screen of the image display unit 16.

  The display control unit 18 controls display of the display screen of the image display unit 16 in accordance with the finger touch position detected by the finger position detection unit 17. In this example, the display control unit 18 includes a hit determination unit 18a, a line end / line start determination unit 18b, a finger position stop determination unit 18c, and a mode setting unit 18d.

  Hereinafter, the operation of the display control unit 18 will be described in detail.

  The display control unit 18 displays the document on the display screen based on the document image data stored in the position setting storage unit 15. Since the display flag of each sentence element of the document is set to an initial value and is OFF, it is displayed with a weak contrast. Here, the weak contrast means that the display density of characters is low. FIG. 2A schematically shows an example in which characters are displayed lightly, and all the characters are indicated by X. In FIG. 2A, 10 indicates a document display device, and 16 a indicates a display screen of the image display unit 16.

  When the finger position detection unit 17 detects the touch position of the finger, the touch position is input to the display control unit 18. The hit determination unit 18a of the display control unit 18 searches the position setting storage unit 15 to determine whether there is a sentence element at the display position corresponding to the input touch position, and there is a sentence element at the display position corresponding to the touch position. If it is, it is determined that it is a hit, and the display flag of the sentence element is turned ON.

  When determining whether or not the touch position matches the display position of the sentence element, the display area of the sentence element is enlarged by a predetermined range to set a hit area. In other words, even if the touch position is slightly away from the display position of the sentence element, it is determined that it is a hit if it is within a predetermined hit area. The setting of the hit area for the display position of the sentence element is set in advance in the display control unit 18.

  The display control unit 18 emphasizes the contrast for the sentence element that is determined to be a hit and the display flag is turned on, and performs a highlight display control that restores the original weak contrast after a predetermined time. The display flag of the sentence element is turned OFF by executing this highlight display control. In this case, contrast enhancement means increasing the display density of characters.

  FIG. 2B schematically shows an example in which the hit determination is made and the display flag is turned on and the sentence element is displayed darkly. The display state is changed by the touch of the finger 31 on the display screen 16a. As shown in The portion touched by the finger 31 is darkly displayed, and the portion touched in the past is gradually dimmed in this example. FIG. 3 is an enlarged view of this situation.

  FIG. 4 shows differences in highlighting due to differences in analysis units (sentence elements) input from the analysis unit input unit 12.

FIG. 5A shows an example of how the density of the display of sentence elements is changed when the display flag is turned on and highlighting control is performed. T ₀ indicates the time determined to be a win. T _{1 to} T ₄ indicate the time when the density starts to increase, the time when the maximum density is reached, the time when the density starts decreasing, and the time when the density returns to the original low state.

As shown in FIG. 5A, in this example, after the hit determination, the display gradually darkens after a short time, and after the maximum density is maintained for a predetermined time, the display gradually lightens. The time T ₂ -T ₀ from the hit determination to the maximum concentration is desirably within 0.5 seconds, for example, and the maximum concentration duration T ₃ -T ₂ is desirably 1 second or more. Further, the time T ₄ -T ₂ from when the maximum density is reached until the original thin state is restored is preferably within 2 seconds. The time is measured by the time measuring unit 19.

  As described above, in this example, characters are initially displayed lightly on the display screen, and when the user traces them with a finger (touches), the traced characters are the sentence elements entered as analysis units. The display is gradually darkened, and the display gradually becomes lighter after a predetermined time. When reading a document, the user can naturally perform the operation of tracing the reading portion with his / her finger. Therefore, according to the document display device described above, it is possible to cope with the user's natural reading speed and reading catch. Also, the user can concentrate only on the part being read.

  When the touch position of the user's finger is continuously moving, the sentence elements are sequentially highlighted in contrast (displayed darkly) according to the touch position of the finger, and then return to the original weak contrast (it is difficult to see). However, when the finger touch position does not change and the finger is stopped, the contrast emphasis display is continued.

  The finger position stop determination unit 18 c of the display control unit 18 determines finger stop from the touch position detected by the finger position detection unit 17 at a predetermined time interval and input from the finger position detection unit 17. If the finger touch position does not change and there is a sentence element at the display position corresponding to the touch position, the display control unit 18 continues the contrast-enhanced display of the sentence element. The finger stop state is determined based on the fact that the touch position does not change at all. Instead, a predetermined threshold value is set in advance, and if the change in the touch position is within the threshold value, it is determined that the touch position is stopped. Also good.

  Note that when the stop state of a finger is determined and contrast highlighting of the sentence element at that position is continued, the display flag of the sentence element located before the sentence element is turned ON in the line where the sentence element is located. All sentence elements up to the position of may be displayed with contrast emphasis.

  Next, display control when the touch position of the finger corresponds to the end of a line or the beginning of a line will be described.

  The line end / line start determination unit 18b of the display control unit 18 determines whether the finger touch position detected by the finger position detection unit 17 is the line end or the line start. When the touch position is at the end of the line and the sentence element at the display position corresponding to the touch position does not extend over the next line, the display control unit 18 simultaneously turns on the display flag for the sentence element at the beginning of the next line, and the contrast. And emphasis display control for restoring the original weak contrast after a predetermined time.

  FIG. 6B shows this state. In addition to the sentence element e2 positioned at the touch position of the finger, the contrast of the sentence element e3 at the beginning of the next line is also emphasized. By doing in this way, it can avoid that a user loses sight of a line. As shown in FIG. 6A, when the sentence element e1 extends over the next line, there is no fear of losing the line.

On the other hand, when the touch position is the beginning of a line and the sentence element at the display position corresponding to the touch position starts from the beginning of the line, the display control unit 18 controls the display of the sentence element at the end of the previous line, Make the time to return to weak contrast longer than usual. That is, the time T ₄ -T ₂ in FIG. 5A is lengthened. By doing in this way, the operational feeling at the beginning of a line can be improved, for example.

In the example described above, the density change of the display by contrast emphasis display control is assumed to be gradually darker and gradually lighter as shown in FIG. 5A. Instead, this is shown in FIGS. 5B and 5C. It may be controlled so as to change the density. In FIG. 5B, the concentration suddenly increases after a short time after the hit determination time T _{0, and} after maintaining the maximum concentration for a predetermined time, the concentration is decreased rapidly. Further, FIG. 5C does not take a little time after the hit determination time T ₀ as shown in FIG. Such a change in density can also be adopted.

  Next, the display mode input unit 13 and the mode setting unit 18d will be described.

  In this example, as shown in FIG. 1, a vibration presentation unit 21 and a voice presentation unit 22 are provided. The vibration presenting unit 21 and the voice presenting unit 22 convey the fact to the user by vibration or voice when the hit determining unit 18a determines that the hit is true. Voice presentation can be performed.

  Whether or not to present vibration or voice is set in the mode setting unit 18d by an input from the display mode input unit 13.

  In the above-described example, when the finger touch position does not change and the stop determination is made, the contrast-enhanced display of the sentence element at the position is continued. It can be set by an input from the display mode input unit 13.

  Furthermore, the method of changing the density of the display as shown in FIGS. 5A to 5C, the time of highlighting time (time for maintaining the maximum density), and the type of sentence element at the time of increasing or decreasing the density are changed. This can also be input and set from the display mode input unit 13.

  The document display device and the document display method described above can be realized by a computer and a program installed in the computer. The program installed in the computer is decrypted by the CPU of the computer and causes the computer to execute the above-described document display method. The computer may be a so-called electronic book terminal.
