Description

  The present invention relates to a terminal device that receives and processes information from an electronic pen.

  In recent years, electronic pens that digitize written information have been developed, and “Anoto pen” developed by Swedish company Anoto is known as a representative example. Anotopen is used with dedicated paper on which a predetermined dot pattern is printed. In addition to the usual ink cartridge for writing characters, etc., the anotopen has a small camera for capturing the dot pattern printed on the dedicated paper and the position coordinates on the dedicated paper from the captured dot pattern. A processor for calculating and a data communication unit for transmitting the calculated position coordinates and the like to an external device are mounted. When a user writes characters, etc. on the special paper with an annotated pen, or puts a check mark on the image designed on the special paper, the small camera prints a dot pattern printed on the special paper as the pen moves. Information such as characters and images written by the user is recognized from continuous position coordinates obtained by imaging and calculated by the processor. Then, this entry information is transmitted from the Anotopen by the data communication unit to a nearby terminal device such as a personal computer or a mobile phone (for example, see Patent Document 1).

  So far, a document management system has been proposed that records and updates the entered information when a plurality of sheets are filled with the electronic pen using such a system using the electronic pen. (Patent Document 2). It has also been proposed to print a dot pattern on a map book and display a map of a page pointed to by an electronic pen on a terminal device (Patent Document 3). Also, a presentation system has been proposed as a system using a stylus pen and a digitizer (Patent Document 4).

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

<First Embodiment>
[System configuration of presentation system]
As shown in FIG. 1, a presentation system (information providing system) 1A according to the first embodiment provides a presentation sheet 2, a palette sheet 3 for designating a color to be displayed on the display screen, and a listener 4. The electronic pen 7 used by the presenter 6 presenting, the terminal device 8A (8) for receiving the entry information from the electronic pen 7 and displaying the entry content on the display (display means), and the display information from the terminal device 8A And a projector 11 that displays the image on the screen 9.

[Presentation paper]
As shown in FIG. 2, the presentation sheet (also simply referred to as “presentation sheet”) 2 is a document in which sheets 2A, 2B, 2C, and 2D (2) are bound, and each sheet 2 has the same pattern. A dot pattern (encoded pattern) is printed on the entire surface, and further, a date entry column 13 for entering a date, a page number entry column 14 for entering a page number (identification information), and a content entry column for entering announcement contents. 16 is printed. The dot pattern is printed with ink containing carbon that absorbs infrared rays, and the design such as the frame lines of the entry fields 13, 14, and 16 is printed with ink that does not absorb in the infrared region. In each of the entry fields 13, 14, and 16, an entry area (user area) that includes the entry field is set, for example, as an area indicated by reference numeral 14a in FIG.

[Pallet paper]
As shown in FIG. 3, the pallet sheet 3 is a sheet for designating a color when the handwriting written on the sheet 2 with the electronic pen 7 is displayed on the display screen of the terminal device 8 </ b> A or the screen 9. A different dot pattern (coded pattern) is printed on the entire surface with ink containing carbon. Further, the pallet paper 3 designates a color designation area 18 for designating the color of a handwriting line, a fluorescent color designation area 19 for designating a color emitting a fluorescent color, and a thickness (width) of the handwriting line. A line width designation region 20. In the color designation area 18, various colors such as black, white, yellow, gray, blue, red, green, orange, etc. have an N shape (reference numeral in FIG. 3) in an area (user area) 18a for designating each color. 18b) and printed with ink that is aligned in 3 columns and 5 rows and has no absorption in the infrared region. The fluorescent color designation area 19 has an N-shaped design (indicated by reference numeral 19b in FIG. 3) in an area (user area) 19a in which three colors of fluorescent colors blue, yellow, and red designate each color. It is printed with ink that is aligned in three rows and has no absorption in the infrared region. Further, the line width designation area 20 has an N-shaped design (indicated by reference numeral 20b in FIG. 3) in an area (user area) 20a in which lines having different line widths are designated in stages. It is printed with ink that is aligned in 3 columns and 2 rows and has no absorptivity in the infrared region.

[Dot pattern]
Next, the dot pattern (coded pattern) printed on the presentation paper 2 and the pallet paper 3 will be described. FIG. 4 is a diagram illustrating the relationship between the dots of the dot pattern printed on the papers 2 and 3 and the values to which the dots are converted. As shown in FIG. 4, each dot of the dot pattern is associated with a predetermined value depending on its position. That is, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, or right is shifted from the reference position of the grid (intersection of the vertical and horizontal lines). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the sheets 2 and 3 are determined by the combination of the information thus associated.

  FIG. 5A shows an arrangement of a certain dot pattern. As shown in FIG. 5A, 6 × 6 dots are arranged within a range of about 2 mm in length and width so that a unique pattern can be obtained no matter where 6 × 6 dots are taken from any part of paper 2 or 3. Has been. The dot pattern formed by these 36 dots holds position coordinates (for example, where the dot pattern is located on the paper 2 and 3) and a dot pattern address (coded pattern address). FIG. 5B is a diagram in which each dot shown in FIG. 5A is converted into a value associated with the regularity shown in FIG. 4 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 7 that captures an image of a dot pattern.

[Electronic pen]
Next, the electronic pen 7 will be described. As shown in FIG. 6, the electronic pen 7 includes a processor 23 constituted by a CPU, a memory 24 such as a ROM and a RAM, a data communication unit 26 constituted by an antenna, a battery 27, etc. An LED 28, a CMOS camera 29, a clock 31, a pressure sensor 32, and an ink cartridge 33 are provided. The tip of the ink cartridge 33 is a pen tip portion 34, and the presenter 6 brings the pen tip portion 34 of the electronic pen 7 into contact with the presentation paper 2 (refer to FIG. 2) to identify the date and page number (identification). Information) is entered in the entry fields 13 and 14, the contents of the presentation are entered in the content entry field 16, or the pen tip 34 is used to designate the color to be displayed on the screen display of the terminal device 8A. Then, a mark is written on the pallet paper 3 (see FIG. 3) or tapped (tapping the pallet paper 3 by the pen tip 34).

  The battery 27 is for supplying electric power to each component in the electronic pen 7, and is configured to turn on / off the power of the electronic pen 7 itself by, for example, detaching a cap (not shown) of the electronic pen 7. May be. The clock 31 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 23. The pressure sensor 32 measures the pressure applied through the ink cartridge 33 from the pen tip 34 when the presenter 6 writes or taps characters or marks on the presentation paper 2 or the pallet paper 3 with the electronic pen 7, that is, the writing pressure. The detected value is transmitted to the processor 23.

  The processor 23 switches on / off the switches of the LED 28 and the CMOS camera 29 based on the writing pressure data supplied from the pressure sensor 32. That is, when the presenter 6 writes characters or the like on the presentation paper 2 or the like with the electronic pen 7, writing pressure is applied to the pen tip 34, and when the pressure sensor 32 detects a writing pressure exceeding a predetermined value, the processor 23. Determines that the presenter 6 has started the entry, and activates the LED 28 and the CMOS camera 29.

  The LED 28 and the CMOS camera 29 are attached in the vicinity of the pen tip portion 34 of the electronic pen 7, and an opening 36 is formed in a portion of the housing 22 facing the LED 28 and the CMOS camera 29. The LED 28 illuminates infrared rays toward the vicinity of the pen tip 34 on the presentation paper 2 or the pallet paper 3. That region is slightly shifted from the position where the pen tip 34 contacts the paper 2, 3. The CMOS camera 29 captures a dot pattern in the area illuminated by the LED 28 and supplies image data of the dot pattern to the processor 23. Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 28 are absorbed by the carbon contained in the dots. Therefore, the dot portion has a small amount of infrared reflection, and the portion other than the dot has a large amount of infrared reflection. By photographing with the CMOS camera 29, a threshold value is provided based on the difference in the amount of reflected infrared light, so that a dot region containing carbon can be distinguished from other regions. Therefore, the ink printed on the ruled lines in the columns 13, 14, and 16 on the presentation paper 2 and the designated areas 18 to 20 on the pallet paper 3 does not absorb in the infrared region, so the processor 23 recognizes the dot pattern. can do. Note that the shooting area by the CMOS camera 29 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 5A, and the shooting by the CMOS camera 29 is performed at a fixed interval of about 50 to 100 times per second. Is called.

  While the presenter 6 is writing, the processor 23 uses the dot pattern of the image data supplied by the CMOS camera 29 to write the stroke (handwriting) written by the presenter 6 on the papers 2 and 3 on the X and Y coordinates ( Simply referred to as “coordinate data”) and dot pattern addresses (coded pattern addresses) specific to the sheets 2 and 3 are continuously calculated. That is, the processor 23 converts the image data of the dot pattern as shown in FIG. 5A supplied by the camera 29 into the data array shown in FIG. 5B, and further converts the X coordinate bit value · Y The data is converted into a coordinate bit value, and X, Y coordinate data and a dot pattern address are calculated from the data array by a predetermined calculation method. Then, the processor 23 associates the current time (time stamp: entered time information) transmitted from the clock 31, the writing pressure data, the dot pattern address, and the X and Y coordinate data. The 6 × 6 dot pattern on the sheets 2 and 3 does not overlap in the sheets 2 and 3, so when the presenter 6 enters the contents of the presentation with the electronic pen 7, the entered position is on the sheet. It is possible to specify the position of 2 or 3 by coordinate calculation by the processor 23.

  The memory 24 stores property information such as an electronic pen ID such as “pen01” for identifying the electronic pen 7, a pen manufacturer number, and a pen software version. Then, the data communication unit 26 associates the pen ID (electronic pen identification information), time information (time stamp), writing pressure data, dot pattern address, and X, Y coordinate data as terminal information. Transmit to device 8A. Transmission to the terminal device 8A by the data communication unit 26 is performed immediately and sequentially by wireless transmission of Bluetooth (registered trademark).

[Terminal device]
Next, the terminal device 8A will be described. The terminal device 8A includes, as hardware, an antenna device capable of data communication with the electronic pen 7, a processor such as a CPU, a memory such as ROM and RAM, a display, a mouse, a keyboard, and the like, and a personal computer. The FIG. 7 is a functional block diagram of the terminal device 8A. Functionally, the terminal device 8A includes transmission / reception means 41, storage means 42, processing means 43, display means 44, and input means 46 such as a mouse and a keyboard. Then, the terminal device 8A performs a predetermined process by executing the dedicated application 70 based on the entry information received from the electronic pen 7.

  The transmission / reception means 41 includes an antenna or the like, and receives entry information from the electronic pen 7 or transmits display data of the display means (display) 44 to the projector 11. A data transmission method to the projector 11 is as follows. It may be wired or wireless.

  The storage means 42 is configured by a memory such as a ROM or a RAM. As shown in FIGS. 8A and 8B, the storage means 42 is identified by the page number entered in the page number entry column 14 of the presentation sheet 2 for each pen ID of the electronic pen 7 included in the entry information. For each sheet 2A, 2B,..., The entry information is stored, and the line color and line width settings designated by the mark entry or tap on the pallet sheet 3 are stored. Further, as shown in FIG. 8C, the storage means 42 stores the dot pattern address of the dot pattern printed on the presentation sheet 2 and the design data of the entire sheet of the presentation sheet 2 in association with each other.

  Further, as shown in FIG. 8D, the storage means 42 stores each color 18b, 19b printed with an N-shaped design printed in the color designation area 18 and the fluorescent color designation area 19 of the pallet paper 3. Color designation area numbers (area IDs) are assigned to the designated areas (user areas) 18a and 19a, and “black” and “purple” are selected according to the colors printed on the pallet paper 3 in correspondence with the color designation area numbers. The designated color and color data are stored in association with each other such as “yellow”. As shown in FIG. 8E, the storage means 42 is an area (user area) for designating a line 20b printed with an N-shaped design printed in the line width designation area 20 of the pallet paper 3. 20a is assigned a line width designation area number (area ID), and is displayed on the display screen of the terminal device 8A according to the width of the line printed on the pallet paper 3 in correspondence with each line width designation area number. The widths of the lines are stored in association with each other such as 0.5 mm, 1 mm, 2 mm,... (Line width when the presentation sheet 2 is displayed at the same magnification).

  Further, as shown in FIG. 9A, the storage means 42 includes the entire sheet and each entry area (user area) (for example, 14a) on the presentation sheet 2, and each color designation area (user area) 18a on the pallet sheet 3. 19a and the area ID of the designated area (user area) 20a of each line width, the user area name, the dot pattern address, the paper type, and the coordinate area occupied by the area (user area) are stored as definition information in association with each other. ing. Also for the pallet paper 3, the storage means 42 stores the color designation area number (area ID) of each color designation area 18 (user area), the color designation area number (area ID) of each fluorescent color designation area 19 (user area), and each line. Line width designation area number (area ID) of the width designation area 20 (user area), user area name, dot pattern address, paper type (palette paper), and coordinate area occupied by each area (user area) Are stored as definition information. Here, as shown in FIG. 9B, the coordinate area of the user area is defined by a coordinate point (Xn, Yn) of a specific corner, a width Wn in the X direction, and a height Hn in the Y direction. It has been. The storage means 42 is constituted by a memory such as a ROM or a RAM.

  The display unit 44 is configured by a display or the like, and displays the contents instructed by the processing unit 43. The processing means 43 is constituted by a processor such as a CPU, and performs predetermined processing such as displaying entry contents in various forms on the display means 44 based on the entry information received from the electronic pen 7 by the transmission / reception means 41. Execute. Hereinafter, each display form displayed on the display unit 44 according to an instruction from the processing unit 43 will be described.

  FIG. 10 shows a window 50 in which the processing means 43 displays the design of the presentation sheet 2 and the entry contents with the electronic pen 7 on the display means (display) 44 as they are. A window area 51 for displaying contents and a function button area 52 for operating display of the window area 51 are provided. FIG. 10 shows a state in which the entire presentation sheet 2 is displayed.

  When the processing means 43 recognizes that a number has been entered in the page number entry area 14a of the presentation sheet 2 based on the dot pattern address and coordinate data of the entry information received by the transmission / reception means 41, the processing means 43 enters the entry. This number is identified as a “page number” (see FIG. 8A) and is identified from other presentation sheets 2. Then, the processing unit 43 stores the entry information received by the transmission / reception unit 41 in the storage unit 42 for each “page number”. Therefore, when the presenter 6 enters “1” in the page number entry column 14 of the presentation sheet 2A and then enters the date entry column 13 and the content entry column 16 of the presentation sheet 2A, the entry information is stored in the electronic pen. 7 is transmitted to the terminal device 8A, and the processing means 43 of the terminal device 8A recognizes the number “1” entered in the page number entry column 14 by character recognition and stores it as “page number” of the presentation sheet 2A. The area for storing the entry information in the date entry column 13 and the content entry column 16 of the presentation sheet 2A is secured, and the entry information in each entry column is stored.

  Further, when the presenter 6 enters “2” in the page number entry field 14 of the presentation sheet 2B and then enters the date entry field 13 and the content entry field 16 of the presentation sheet 2B, the entry information is sent from the electronic pen 7. Transmitted to the terminal device 8A, the processing means 43 of the terminal device 8A recognizes the number “2” entered in the page number entry field 14 by character recognition and stores it in the storage means 42 as “page number” of the presentation sheet 2B. Thus, an area for storing the entry information in the date entry column 13 and the content entry column 16 of the presentation sheet 2B is secured, and the entry information in each entry column is stored. Similarly, the contents entered on each of the presentation sheets 2C and 2D (2) are stored in the storage means 42 for each “page number”. Here, it is assumed that the presenter 6 always enters a page number in the page number entry column 14 of the present presentation sheet before filling in another presentation sheet 2. For example, when the entry on the presentation sheet 2A is once completed and the presentation sheet 2B is filled in, then the presentation sheet 2A is filled in again. After entering "1", it will be filled in each entry field.

  Further, the processing means 43 stores the entry information in the storage means 42 and simultaneously displays the handwriting entered on the presentation sheet 2 as it is in the window area 51 of the display means 44 based on the coordinate data of the entry information. Here, the electronic pen 7 continuously calculates the coordinate data and the dot pattern address while the presentation sheet 2 is filled in, and transmits the filling information immediately and sequentially to the terminal device 8A. The handwriting display of the window area 51 in the apparatus 8A is realized in real time almost simultaneously with the entry on the presentation sheet 2 by the electronic pen 7.

  Furthermore, when the processing means 43 recognizes that the filled presentation sheet 2 has been changed from the information entered in the page number entry area 14a received by the transmission / reception means 41, the contents entered on the changed presentation sheet 2 The display contents in the window area 51 are switched so as to be displayed. At this time, if there is information that has already been entered in the changed presentation sheet 2 and stored in the storage unit 42, the processing unit 43 reads out the information from the storage unit 42 and has already entered in the presentation sheet 2. After the handwriting is displayed, the handwriting to be newly entered is displayed in the window area 51 based on the entry information transmitted from the electronic pen 7.

  Therefore, for example, when the presenter 6 finishes filling in the presentation sheet 2A and starts to fill in the presentation sheet 2B, the processing means 43 switches the display of the window area 51 from the presentation sheet 2A to the presentation sheet 2B, and the electronic pen On the basis of the entry information transmitted from 7, the entry content (handwriting) on the presentation sheet 2 </ b> B is displayed in the window area 51. When the presenter 6 finishes filling in the presentation sheet 2B and begins to fill in the presentation sheet 2A again, the processing means 43 reads the information already written in the presentation sheet 2A from the storage means 42 and displays the window area 51. Is switched from the presentation sheet 2B to the presentation sheet 2A to display the handwriting written on the presentation sheet 2A so far, and based on the entry information transmitted from the electronic pen 7, the presentation sheet 2A is displayed. A new entry content (handwriting) is added and displayed in the window area 51.

  The color and line width of the handwriting displayed in the window area 51 can be arbitrarily set using the pallet paper 3. That is, the presenter 6 marks or taps designated areas (user areas) 18a and 19a of arbitrary colors from the color designation area 18 and the fluorescent color designation area 19 of the pallet paper 3 with the electronic pen 7, and the pallet paper 3 The designated area (user area) 20a having an arbitrary line width is marked or tapped with the electronic pen 7 from the line width designation area 20 of the above. The electronic pen 7 transmits the entry information including the dot pattern address of the pallet paper 3 and the coordinate data of the marked or tapped user area to the terminal device 8A. In the terminal device 8A, the processing means 43 determines the correspondence between the dot pattern address and coordinate area stored in the storage means 42 and the user area from the information entered on the pallet paper 3 received by the transmission / reception means 41 (see FIG. 9). (A)), the paper type and area ID of the user area are specified, and the correspondence between the color designation area number (area ID), the designated color and the color data (see FIG. 8D), By referring to the correspondence relationship between the line width designation area number (area ID) and the line width (see FIG. 8E), the designated color and the designated line width are recognized, and the presentation paper 2 received thereafter is displayed. The entry information is displayed in the window area 51 with the specified color and the specified line width. The designation of color and line width can be changed at any time by marking or tapping on the pallet paper 3 of the electronic pen 7, and when it is not designated, it is displayed in black and 0.5 mm width by default.

  Next, the function button area 52 for operating the display of the window area 51 will be described. When the processing means 43 recognizes that the “previous paper” button 53 has been clicked with the mouse (input means 46), the processing means 43 immediately before the “page number” of the presentation paper 2 displayed in the window area 51 at that time.

<Processing flow by the presentation system>
Next, a processing flow by the presentation system 1A of the first embodiment will be described with reference to FIG.

  The presenter 6 prepares a plurality of presentation (presentation) sheets 2. First, the pen tip portion 34 of the electronic pen 7 is pen-down (contacted) with respect to the page number entry column 14 of the presentation sheet 2 </ b> A. Start filling page number “1”. At this time, the electronic pen 7 detects a contact with the presentation paper 2A when the pressure sensor 32 detects a writing pressure of a predetermined value or more (step S101), and irradiates infrared rays with the LED 28 and creates a handwriting with the camera 29. The dot pattern is imaged along with the coordinate data (coordinate data within the range of “(X2, Y2), W2, H2”) and the dot pattern address from the image data of the captured dot pattern by the processor 23. ("108.201.1.1") is calculated and associated with the time stamp, writing pressure data, and pen ID ("pen01"), and is immediately and sequentially transmitted to the terminal device 8A as entry information (step S102). ).

  When the presenter 6 finishes writing the page number “1” and the pen tip portion 34 of the electronic pen 7 is pen-up (detached), the electronic pen 7 does not detect a writing pressure of a predetermined value or more by the pressure sensor 32. As a result, separation from the presentation sheet 2A is detected, and transmission of entry information to the terminal device 8A is interrupted (step S103). Subsequently, the presenter 6 enters the pen tip portion 34 of the electronic pen 7 in order to fill in the date entry column 13 and the content entry column 16 of the presentation sheet 2A, the other presentation sheets 2B, 2C,. When the electronic pen 7 is down (Step S104: Yes), the electronic pen 7 repeats the processing of Steps S101 to S104, and does not detect the next pen down for a predetermined time (for example, 15 seconds) in Step S104 (Step S104: No), the transmission of the entry information to the terminal device 8A is terminated.

  On the other hand, when the terminal device 8A receives the entry information on the presentation sheet 2A from the electronic pen 7 by the transmission / reception means 41, the processing means 43 stores the entry information in the storage means 42 (step S201), From the included pen ID, it is specified that the entry information is entered by the electronic pen 7 with the pen ID “pen01”, and the dot pattern address (“108.201.1.1”) contained in the entry information is further specified. Referring to the definition information (see FIG. 9A) stored by the storage means 42 based on the above, the paper type (“presentation paper”) corresponding to the entry information is specified (step S202: presentation), and then The definition information is referred to based on the coordinate data included in the entry information (coordinate data within the range of “(X2, Y2), W2, H2”), and the entry information Corresponding user area is identified as a page number entry column 14 (step S203: Yes). Then, the processing unit 43 recognizes the entered page number by character recognition, and whether the recognized number “1” is stored in the storage unit 42 as the “page number” of the presentation sheet 2A related to the pen ID “pen01”. If it has not been stored, it is determined that the page is a new page (step S204: YES), and an area for storing the entry information of the presentation sheet 2A is secured in the storage means 42 (step S205). The processing means 43 temporarily stores the entry information in the temporary storage area of the storage means 42, and stores the entry information in the storage area when the area for storing the entry information in the storage means 42 is specified.
