  The operation icon 102G is for performing a search operation, and can perform a search according to the number of learning histories (number of taps) and the type of mask, as will be described later. The operation icon 102H displays, for example, a ratio of “completely understood”, “anxious place”, “don't remember”, and “unlearned” for the portion masked by the mask 102B. When this icon is tapped, the mode can be shifted to a mode for acquiring various statistical information. This will be described later.

  4 schematically shows a hardware configuration of the tablet computer 100 (FIG. 1). In this figure, the tablet computer 100 includes a CPU 10, a RAM 11, a ROM 12, a touch panel 13 (a position input unit 14 and a display unit). 15), an audio processing unit 16, a wireless transmission / reception unit 17 including an antenna, a microphone / speaker 18, a bus system 19 and the like.

  The position input unit 14 is used to input a position and a change thereof with a touch pen, a finger, and the like, and various operations are executed based on a position input event. The liquid crystal panel of the display unit 15 displays text, graphics, images, and the like. The CPU 10 executes a system program such as an operating system, a middleware program, and an application program (including a document browsing program) together with a RAM (main memory) 11. The ROM 12 is typically a flash memory, and stores a boot program, an operating system, a middleware program, an application program, and other various data.

  In this example, a document browsing program is executed on the tablet computer 100, and the content of the material layer is displayed with the marker layer masked as shown in FIG.

  FIG. 5 schematically shows a configuration of a document browsing apparatus realized by executing a document browsing program in the tablet computer 100 using functional blocks. Each functional block is a functional means realized by cooperating the hardware of the tablet computer 100 and the document browsing program. In FIG. 5, the document browsing apparatus includes a storage unit 210 and an operation unit 220. The storage unit 210 is typically configured to include the RAM 11 of FIG. The operation unit 220 is realized as a subroutine executed by the CPU 10.

  The storage unit 210 includes a material data storage area 211, a mask position information storage area 212, a mask display attribute storage area 213, a tap count storage area 214, and the like. The material data storage area 211 is material data, typically portable document format document data or EPUB format document data, but is not limited thereto. The material data can be obtained from the external server computer 200 or the like. A memory card may be mounted and the material data recorded on the memory card may be used. The mask position information storage area 212, the mask display attribute storage area 213, and the tap count storage area 214 are recorded in a format as shown in FIG. 6, for example. In this example, a mask ID is assigned to each mask, and the mask start position, end position, mask display attribute, and tap count are stored in association with each mask. The start position and end position of the mask are described according to the type of material data. In material data having the concept of a page, it may be defined by a page and coordinates in the page, but is not limited to this. In the case of material data having no page concept, it can be defined by the character position, but is not limited to this. The display attributes of the mask are “green”, “yellow”, “red”, and “white” corresponding to “completely understood”, “anxious part”, “don't remember”, and “unlearned”. The code is stored.

  The operation unit 220 includes a document operation unit 221, a mask operation unit 222, a search unit 223, and the like. The operation unit 220 receives an input from the position input unit 14, performs various processes based on the input, and displays on the display unit 15. The document operation unit 221 is used to specify browsing of a document. Select a document from the list of material data, and select the continuation (bookmark) from the previous time, bookmark selection, display from the beginning, and random page with the start option. When selecting the start option, the previous end page or the like may be displayed by default on the back of the option selection window.

  The mask operation unit 222 executes mask formation and correct answer display operations. The correct answer display operation is an operation for displaying a portion hidden by the mask. Typically, the mask area may be transparent or translucent. The part (correct answer) may be displayed by a balloon or the like. An example of the operation of the mask operation unit 222 will be described later. The search unit 223 searches and extracts a mask based on the display attribute of the mask and the number of taps. An operation example of the search unit 223 will also be described later.

FIG. 7 illustrates an example of the mask formation operation of the mask operation unit 222. The operation example is as follows.
[Step S11]: It is determined whether or not the marking icon has been tapped. When tapped, the process proceeds to step S12.
[Step S12]: It is determined whether the tap position is the pen tip of the marking icon. If it is a pen point, the process proceeds to step S13. If it is not a pen point, the process proceeds to step S15.
[Step S13]: A pen selection option is displayed as shown in FIG. 3B.
[Step S14]: When the pen tip option is selected, the marking pen mode is set to that option. When an empty area other than the nib option is specified, the marking pen mode is left as it is. Thereafter, the process proceeds to step S15.
[Step S15]: The position of the mask is determined in the current marking pen mode based on the input of the touch pen. For example, as shown in FIG. 8, in the thickness (height) designation mode, a mask is formed that fills between adjacent tap positions X at that height. In the case of free designation, a mask is formed that fills a rectangle whose diagonal points are successive tap positions X.
[Step S16]: A new mask ID is assigned, and the coordinates of the opposite diagonal points of the formed mask are stored as mask coordinates. Since the mask is a new mask, the initial value (white) ) To set the number of taps to zero.
[Step S17]: A mask is displayed using new mask data.

  When the material data is image data or the like and the coordinate position is directly handled, a mask is drawn on the marker layer based on the coordinate position of the mask. When the material data is described by a character code, the character at the start position and the character at the end position may be discriminated from the tap position information, and the black solid character may be rasterized at the corresponding position to draw the marker layer. . As described above, the mask may be overwritten on the display buffer of the material data being displayed without drawing on the marker layer.

  If it is desired to set various initial display attributes, a step of selecting display attributes may be added. Further, the number of taps may be displayed in or near the area of the mask as shown in FIG. In this example, the number of taps is 3 times.

FIG. 10 shows an operation example when the mask is tapped. An example of this operation is as follows.
[Step S21]: It is determined whether or not the mask has been tapped. If tapped, the process proceeds to step S22.
[Step S22]: A portion (correct answer) hidden in the tapped mask is displayed. For example, the mask color may be lightened so that the hidden portion is raised, or the mask may be displayed with inverted white.
[Step S23]: Display attribute options are displayed as shown in FIG. 11, for example. In this example, “green”, “yellow”, and “red” are displayed in correspondence with “completely understood”, “anxiety”, and “don't remember”, and green, yellow, and red are displayed. Can be selected. Since “white” is an initial value, there is no need to display it. However, when it is desired to select an initial value, “white” may be included in the option.
[Step S24]: It is determined whether an option or an area outside the option has been tapped. If an option is selected, the process proceeds to step S25. If an option outside is selected, the process proceeds to step S26.
[Step S25]: The value of the corresponding mask display attribute storage area is changed with the mask display attribute corresponding to the selected option. Proceed to step S26.
[Step S26]: The mask is restored to the original non-display.

  12 to 14 illustrate an example of a search operation. The search operation is started, for example, by tapping the search icon in FIG.

  FIG. 12 shows an example of a search operation, and this operation example is as follows. In this example, the number of taps and the display attribute are adopted as the search conditions. However, the date and time of mask formation, the last date and time of tap of the mask, etc. may be adopted. In this case, it is necessary to appropriately store and hold data such as the last date and time of tap and the date and time of mask formation.

[Step S31]: It is determined whether or not the search icon has been tapped. If tapped, the process proceeds to step S32.
[Step S32]: A search condition designation screen is displayed. In the search condition designation screen, for example, display attributes and the number of taps can be input as shown in FIG. In this figure, “green”, “yellow”, “red”, and “white” characters are displayed, but the characters themselves may not be present. The number of taps is not limited to, for example, although a desired value is input by tapping an upward icon and a downward icon. The condition that the number of taps is less than the specified number, exceeds the specified number, or equals the specified number is specified by an equal sign or an inequality sign. If the search execution is tapped, the process proceeds to step S33.
[Step S33]: A mask that matches the designated display attribute and the number of taps is selected, and strip-like regions including the mask are connected and displayed as shown in FIG. The strip-shaped windows 101w may be connected and displayed, and the material data portions corresponding to these windows may be displayed in a mask state.

  When the mask is tapped in the display state of FIG. 14, the portion hidden by the mask is displayed, and the display attribute option of FIG. 11 is also displayed, but is not limited thereto.

  A publisher or the like may prepare a masked document in a manner such as a problem collection. In this case, user operations for existing masks may be collectively managed by a server computer, and a search based on the statistical data may be performed. For example, 60% of people may search for a part that is “completely understood” or 70% of people may search for a part that has been tapped once or more. The search result may be displayed as shown in FIG. A user may form a unique mark in a document in which an existing mask is set and manage it individually. Although not limited to this, when the document is described in PDF, XML, HTML, etc., the existing mask information (position and position (perfect / anxiety / mistake) of the masked portion, information on the number of taps) Including, but not limited to) may be marked with a tag such as XLM held in the data as an attribute of the character information and embedded in the material data itself. In this case, the portion designated by the mask tag in the document performs a desired operation such as option selection shown in FIG. 11 or the like according to the tap, and further updates the display attribute and the number of taps. ). In the initial state, the display attribute is, for example, “white” and the number of taps is zero. However, the display attribute is updated to a selection attribute (for example, “green”, “yellow”, “red”) according to the tap, and the number of taps is also Increment. In addition, the browsing software prepared exclusively for this embodiment extracts mask information contained in a document such as PDF, XML, HTML, etc., displays the mask, manages the attribute / tap count, and masks at the end of browsing. Information may be back-filled in a document. The mask information embedded in the document can be sent as it is in the document state or extracted from the document to the server computer, and can be used as statistical information on the server computer or the like.

  Further, when the operation icon 102H of FIG. 1 is tapped, the details of the statistical information as shown in FIG. 1 may be displayed. FIG. 15A is an example of a document masked by each user, and FIG. 15B is an example in which a plurality of users use a masked problem collection. In the case of FIG. 15B, the server computer can be accessed via the network.

  This is the end of the description of the embodiment.

  In addition, this invention is determined based on description of a claim, and is not limited to the specific structure of the Example, a subject, and an effect. The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. In the above-described embodiments, description has been made with reference to an example using a tablet computer, but a personal computer, a portable game machine, a video game machine, an electronic dictionary, a portable information device, an electronic camera, a digital photo frame, a television receiver, The same applies to other electronic devices.

  In the above example, the marker layer can be turned on / off by tapping the operation icon 102C. Although we wanted to explain in the above example, the marker layer was turned on, similar to the conventional learning method of masking the marking part using the marker pen and the specific underlay (color of the color of the marker pen and the complementary color). In this case, the material data may be colored with a light color. For example, the background color of the material data may be changed to a light color, and then the mask area of the marker layer may be overwritten with the mask color. Of course, it may be the same color as the display of only the material data (display when the marker layer is off).

  In addition, the part hidden by the mask is transparent as it is (the frame is displayed in attribute color, or only the underline is displayed instead of the mask rectangle, and the underline color is changed to the attribute color), translucent, white, etc. The mode displayed with may be set. In this way, it is possible to continue reading the answer while being aware of the certainty of the correct answer, and to learn in a short time.
