2. Description of the Related Art In recent years, information processing apparatuses capable of handwriting input for inputting characters and pictures by tracing a display unit with a finger or a stylus pen in a PC (Personal Computer), a PDA (Portable Digital Assistant), and the like have been provided. Normally, in handwriting input to the display unit, an input information display area in which information input in the display unit is displayed and a handwritten region in which handwriting input is performed exist in separate locations.

When the handwritten area and the input information display area are thus separated, the input information display area must be displayed, and the handwritten area in the display unit is reduced. Then, the user has to write in a narrow handwritten area, and complicated input may be difficult. In addition, the handwriting area becomes smaller due to the recent downsizing of information processing apparatuses and the adoption of touch panels for mobile phones, and this problem is expected to increase in the future.

In view of the above problems, in an information processing apparatus that recognizes handwritten characters, converts them, and inputs them as normal text data, it is possible to perform handwriting in the input information display area, and handwriting input is performed. In addition, a handwritten character input device has been proposed in which the input information display in the rectangular area surrounding the handwritten stroke is made translucent so that the input information display can be easily written in a wide area (Patent Document 1). reference).

  FIG. 4 is a diagram showing an example of display on the LCD 26 when executing the handwriting application in the present embodiment. FIG. 4 shows a handwriting application window 41, an input stroke information display area 42, a locus stroke 43, an input stroke 44, and a drawing size setting display 45.

  Handwriting input on the PC 10 in the present embodiment can be performed when the handwriting application is executed. A program for the handwriting application is stored in the HDD 24. The CPU 21 extracts the program according to a user instruction and executes a handwriting application, thereby enabling handwriting input.

  As a user input method for handwriting input, an input method using a stylus pen is also conceivable. In this embodiment, handwriting with a finger in contact will be described as an example.

  The handwriting application window 41 is a window displayed on the LCD 26 when the handwriting application is executed, and handwriting stroke information is input to the PC 10 by the user performing handwriting with a finger in this window area. In this embodiment, although it illustrates as what can be handwritten in the handwriting window 41, it is not limited to this, You may be able to handwritten on the display part 11 whole. Also in this embodiment, it is possible to perform handwriting on the entire display unit 11 by maximizing the handwriting application window 41.

  The input stroke information display area 42 is an area where an input stroke is displayed. When the user performs handwriting input, an input stroke drawn in a predetermined size is displayed in this area.

  The trajectory stroke 43 is a stroke for displaying a trajectory that the user has handwritten on the display unit 11 (traced with a finger). In this embodiment, the locus stroke 43 is translucent and is drawn and displayed with a thick line and a color different from the input stroke 44. In FIG. 4, translucency is expressed by a broken line.

  The input stroke 44 is a stroke input to the PC 10 from handwritten stroke information. In the present embodiment, the input stroke 44 can change the drawing size setting for the handwritten stroke.

  The drawing size setting display 45 is displayed in the handwriting application window 41 and can be set by using the touch panel function to set the drawing size ratio of the input stroke 44 to the handwriting stroke. The drawing size ratio here is not simply a ratio relating to the display size of the input stroke, but a ratio of the drawing size of the input stroke to the input stroke information display area 42. FIG. 4 illustrates an example in which the drawing size ratio of the input stroke 44 to the handwritten stroke is 20%. In the present embodiment, the size setting reference of the input stroke 44 is illustrated as being displayed as a size ratio with respect to the handwritten stroke. However, the present invention is not limited to this, and it is possible to change the size of the input stroke. It is not limited to this standard. The drawing size ratio that can be set in the drawing size setting display 45 is exemplified as 0% to 100% (exactly 0% does not exist), but is not limited to this. It is also possible to display the input stroke 44 enlarged from the handwritten stroke such as 0% to 200%. When the input stroke reduced from the handwritten stroke is displayed as in the present embodiment, it is possible to input a small input stroke in a large amount by handwriting.

In the present embodiment, when the user contacts the display unit 11 with a finger, the touch detection unit 28 detects the contact. Based on the detection information from the touch detection unit 28, the input control unit 27 outputs the touched coordinate value information to the CPU 21. The CPU 21 determines whether or not the area touched by the user is within the drawing size setting display area 45, and if it is within the drawing size setting display area 45, changes the drawing size setting when drawing the input stroke. If the area touched by the user is not within the drawing size setting display 45 area, the CPU 21 recognizes it as a handwritten stroke, and instructs the GPU 25 to draw an input stroke and a locus stroke. The GPU 25 draws the input stroke and the trajectory stroke according to the drawing instruction from the CPU 21, superimposes the image information, and displays the image information on the LCD 26.
At this time, in this embodiment, the trajectory stroke is translucent as described above, and is displayed in a thick line and a color different from the input stroke. In this case, when the trajectory stroke and the input stroke overlap, it is possible to recognize both the trajectory stroke and the input stroke character by being translucent. Even if the line type of the trajectory stroke line is changed, for example, drawing with a broken line or the like is performed, the same effect as described above can be obtained. Further, by displaying the trajectory stroke with a bold line, it is possible to avoid the danger of recognizing the input stroke and the trajectory stroke in a mixed manner. Displaying the input stroke and the trajectory stroke in different colors can similarly avoid a mixture of recognition. In this embodiment, the locus stroke is exemplified as a thick line. However, since it is only necessary to avoid a mixture of recognition, if the locus stroke is different from the input stroke and the line thickness (the locus stroke is represented by a thin line). Yes) Also, these settings of semi-transparency, thick line, color, etc. may be changeable. When the setting can be changed, when the user inputs a setting change with the touch panel function, the keyboard 12, the touch pad 13, etc., the input control unit 27 transmits the setting change input information to the CPU 21, and the CPU 21 changes the setting to the GPU 25. Instructs drawing of the stroke. The GPU 25 draws a locus stroke corresponding to the instruction and displays it on the LCD 26 together with the input stroke.

  FIG. 5 is a diagram showing an example of display on the LCD 26 when the handwriting application is executed in the present embodiment. FIG. 5 shows a handwriting application window 41, an input stroke information display area 42, a trajectory stroke 43, an input stroke 51, and a drawing size setting display 52. FIG. 5 is a diagram in a case where the drawing size setting is changed and handwriting writing similar to that in FIG. 4 is performed.

  In FIG. 5, the drawing size setting of the drawing size setting display 52 is set to 40%, and the input stroke 51 with respect to the handwritten stroke is drawn and displayed with a size of 40%. In this way, the drawing size of the input stroke 51 can be changed by changing the drawing size setting. In the present embodiment, the drawing size setting on the drawing size setting display 52 using the touch panel function is illustrated, but the present invention is not limited to this, and the drawing size setting is changed by other input means. Good. Examples of other input means include a keyboard 12 and a touch pad 13.

At that time, the input control unit 27 receives a setting change instruction by the user from the keyboard 12 and the touch pad 13 and transmits it to the CPU 21, whereby the CPU 21 changes the drawing size setting of the input stroke 51.

  FIG. 6 is a diagram illustrating an example of a method for moving an inputtable area in the present embodiment. FIG. 6 shows a handwriting application window 41, an input stroke information display area 42, a locus stroke 43, an input stroke 44, a drawing size setting display 45, a locus stroke 61, and an area 62.

FIG. 6A shows the same display as FIG. 4, and FIG. 6B shows the display after the input available area is moved using the multi-touch function from the display of FIG. 6A. . The input enabled area here is an area in the input stroke information display area 42 where the user can input an input stroke, and corresponds to an area in the handwriting application window 41 where handwriting input is possible. In the handwriting application in the present embodiment, the drawing area can be moved using the multi-touch function of the touch panel. As shown in FIG. 6A, when the user touches the display unit 11 with two fingers (at two contact points) and moves the finger on the display unit 11 as it is, the trajectory stroke 43 becomes the handwriting application window 41. It moves by the amount of movement in the finger moving direction, and becomes the position of the locus stroke 61 in FIG. As a result, the input stroke input area of the input stroke information display area 42 is moved, and the input stroke can be input to the area 62 in FIG. 6B. In the present embodiment, the area 62 is shown for explanation and is not actually displayed on the LCD 26. However, the present invention is not limited to this, and the area 62 may be displayed on the LCD 26.

When the touch detection unit 28 detects a finger touch on two points on the display unit 11 at the same time, the input control unit 27 inputs the contact information to the CPU 21. Based on the input information from the input control unit 27, the CPU 21 determines that the touch is a multi-touch in which two points are touched. The GPU 25 is instructed to move and draw by the amount of movement, and the input position of the input stroke is relatively changed.

By performing the above processing, the position of the trajectory stroke moves and the position where the input stroke can be input in the input stroke information display area 42 is changed. Therefore, the user can use the screen widely and continuously with handwritten input so far. It is possible to perform handwriting. In this embodiment, the input stroke input area in the input stroke information display area 42 is changed by the multi-touch function. However, the present invention is not limited to this, and other input methods such as a user using the keyboard 12 or the touch pad 13 are used. The input stroke input area may be changed by an operation.

  Further, the input area of the input stroke and the drawing size of the input stroke may be changed using the multi-touch function. For example, when the user moves the two fingers away while performing multi-touch while displaying the area 62, the locus stroke is enlarged and displayed, and the area 62 is reduced correspondingly. Accordingly, the drawing size of the input stroke is reduced accordingly. Conversely, when the fingers are brought closer to each other, the trajectory stroke is reduced and the area 62 is enlarged correspondingly. Accordingly, the drawing size of the input stroke increases. In this way, the user can perform an input operation intuitively. Further, the enlargement / reduction function by multi-touch and the movement of the locus stroke and the region 62 by multi-touch may be performed simultaneously.

  Further, the display / non-display of the trajectory stroke may be switched. If it is possible to switch the display / non-display of the trajectory stroke, it becomes easier for the user to confirm the display of the input stroke. When the display / non-display of the locus stroke is switched to make it non-display, the display of the input stroke and the correspondence of the input to the user operation event may be different from the display state. For example, when the user performs a double touch in which the same location on the display unit 11 is touched twice at intervals of a predetermined time or less, or when the finger is not slid in a multi-touch state, the trajectory stroke is displayed / hidden. It is good. When the locus stroke is not displayed, the input stroke and the area 62 are enlarged by performing an operation of spreading the finger in multi-touch. Conversely, when an operation of bringing a finger closer is performed, the input stroke and the area 62 may be reduced. After performing these operations, when the trajectory stroke is displayed again by double touch etc., the display size of the trajectory stroke is not changed, and if the user performs handwriting, the input stroke information display area The input stroke may be input at the same size ratio as the ratio at which the input stroke displayed on the screen is enlarged / reduced. With this function, the user can change the drawing ratio of the input stroke.

  When the locus stroke is not displayed, the user touches and slides the display portion of the area 62 of the display unit 11, so that the area 62 corresponds to the movement direction and movement amount of the finger at that time. You may move. Further, regarding the movement of the area 62, it may be moved to a place touched by the user in the input stroke display area 42. If the locus stroke is displayed again at this time, the locus stroke corresponds to the input stroke existing in the area 62. The movement of the area 62 and the switching from the non-display of the trajectory stroke to the display may be performed by multi-touch without sliding. When the area 62 is moved by multi-touch, the size of the area 62 is determined according to the interval between two fingers that have performed multi-touch. Since the ratio of the vertical and horizontal lengths of the rectangular region 62 is determined by the shape of the handwritten application window 41 in the handwritten application window 41, when the user performs multi-touch with the finger substantially horizontal, The distance between the right edge and the left edge is the distance between the fingers, or the distance corresponding to that distance (for example, the distance between the right edge and the left edge of the region 62 is a length that is 80% of the finger sensation. ). When the user performs multi-touch with the finger substantially vertical, the distance between the upper and lower ends of the area 62 is the distance between the fingers, and when the finger is inclined, the distance between the diagonals of the area 62 is the distance between the fingers. It may be. If comprised in this way, the user can change the position which draws an input stroke intuitively.

  FIG. 7 is a flowchart showing an example of a processing flow of handwriting input processing in the present embodiment.

  When handwriting input is performed in the present embodiment, a handwriting application is first activated. When the handwriting application is activated, the CPU 21 determines whether or not an instruction to change the drawing size of the user's input stroke has been made based on the input information from the input control unit 27 detected by the touch detection unit 28 (S701). . If the user gives an instruction to change the drawing size (Yes), the drawing size is changed according to the instruction (S702). When S702 ends, the processing flow returns to S701 again. If the drawing size setting change instruction is not issued in S701 (No), the CPU 21 determines whether or not the user has moved the finger by multi-touch (S703). If there is a multi-touch finger movement (Yes), the GPU 25 is instructed to draw the locus stroke by moving it in the movement direction of the finger, and the input stroke information in the input stroke information display area 42 is displayed. The input possible area is changed (S704). When S704 ends, the process returns to S701 again. If the CPU 21 determines that there is no finger movement due to multi-touch in S703 (No), the CPU 21 then determines whether or not a handwritten stroke has been input (S705). When the input of the handwritten stroke is detected (Yes), the CPU 21 instructs the GPU 25 to draw a locus stroke (S706), and also instructs the GPU 25 to draw an input stroke with the set size ratio (S707). When the GPU 25 draws the locus stroke and the input stroke, it superimposes the image information (S708) and outputs the image information to the LCD. Next, the LCD displays image information from the GPU 25 (S709). When the process in S709 ends, the process flow returns to S701. If the CPU 21 does not detect a handwriting stroke in S705 (No), the CPU 21 waits for a handwriting application termination instruction from the user (S710). If the handwriting application end instruction is not accepted (No), the processing flow returns to S701. When the handwriting application end instruction is accepted in S710 (Yes), the CPU 21 ends the handwriting application (S711), and the series of processing flow ends.

If the information processing apparatus in this embodiment is used, the user can perform handwriting input with a desired size on the display unit while visually recognizing the input stroke. In addition, by making the drawing size of the input stroke smaller than the handwriting stroke, it is possible to perform large handwriting input even when making a small input. By using the information processing apparatus in this embodiment, both the input stroke and the locus stroke Is displayed, the user can view both of them at the same time, and can input an input stroke with a suitable size intuitively. Further, it is possible to input an input stroke while confirming the positional relationship with the input stroke input so far.

Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
