Description

  The present invention relates to a terminal device that gives an instruction to print an image relating to a handwritten stroke, an electronic pen system including the terminal device, and a program executed by the terminal device.

  In recent years, electronic pens that digitize written information have been developed, and “Anot pen” developed by Swedish company Anoto is known as a representative one. 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 the user writes characters on the special paper with an anotopen or puts a check mark on the image designed on the special paper, the small camera captures the dot pattern printed on the special paper as the pen moves. The entry information such as characters and images written by the user is recognized from the continuous position coordinates 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).

  Patent Document 2 describes a rotation correction processing function that corrects an arrangement of dots on an image caused by an angle of an electronic pen facing a dot pattern. Japanese Patent Application Laid-Open No. 2004-228688 discloses a technique for displaying a list of the same ranges in each answer sheet in a collaborative learning system using an electronic pen when an arbitrary position / size range is designated on a display screen. Patent Document 4 discloses a technique for specifying a stroke to be displayed by inputting a writing start time and a writing end time in paper control in a class support system.

[System configuration of electronic pen system]
FIG. 1 is a system configuration diagram of an electronic pen system 10 according to the present embodiment. As shown in FIG. 1, the electronic pen system 10 provides answer sheets (entry sheets) 5A, 5B,... (5) distributed to each student (entrant) and answer sheets (handwriting) on the answer sheet 5. The electronic pens 1A, 1B,... (1) for transmitting the entered information to the outside by a wireless communication method such as Bluetooth (registered trademark) and the entry information transmitted from each electronic pen 1 are received. An aggregating device (terminal device) 2 for displaying entry contents and the like on a display (display means), and a printer 7 for printing answer printing paper 9 (see FIG. 16), which will be described later, in accordance with a print instruction (output command) from the aggregating device 2 .

  In FIG. 1, the aggregation device 2 receives the entry information directly from the electronic pens 1 </ b> A to 1 </ b> C. However, since there are many answer sheets 5 to be filled in, the number of electronic pens 1 that transmit the entry information is large. If the location where the student answers is out of the range of the wireless communication due to the remote location, etc., the entry information transmitted from the other electronic pens 1D, 1E,. A transfer device 3 for transferring is provided. At this time, transmission of data from the transfer device 3 to the aggregation device 2 may be performed by a TCP / IP communication method via a LAN, for example. Each electronic pen 1 can use an anotopen, the aggregation device 2 can use a laptop personal computer, etc., and the transfer device 3 can use a laptop personal computer or a data transfer dedicated computer. can do. The projector 4 is a device that receives display information from the aggregation device 2 and projects and displays the screen of the aggregation device 2 on the screen 6.

[Answer sheet]
The answer sheet (entry form) 5 will be described with reference to FIG. As shown in FIG. 2, a set of a plurality of answer sheets 5 is prepared for each student, and dot patterns (coded patterns) in different coordinate ranges are printed on the same answer sheet 5. Further, squares are printed on the answer sheet 5. The dot pattern is printed with ink containing carbon that absorbs infrared rays, and the squares are printed with ink that does not absorb in the infrared region. The answer sheet 5 may be printed with an entry field, a question, an answer field, and the like.

[Answer sheet, correspondence between electronic pen and students]
As for the correspondence between the answer sheet, the electronic pen and the student (entrant), in this embodiment, as shown in FIG. 3, the student “Taro” answers the answer sheet 5A using the electronic pen 1A, The student “Jiro” answers the answer sheet 5B using the electronic pen 1B, the student “Saburo” answers the answer sheet 5C using the electronic pen 1C, and the student “Shiro” uses the electronic pen 1D. It is assumed that the student “Goro” answers the answer sheet 5E using the electronic pen 1E. Further, it is assumed that a lecturer (operator) “Hanako” operates the aggregation device 2.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) printed on the answer sheet 5 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram for explaining the relationship between the dots of the dot pattern printed on the answer sheet 5 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. In other words, 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 line and horizontal line). 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 paper are determined by the combination of the information thus associated.

  FIG. 5A shows an arrangement of a certain dot pattern. As shown in FIG. 5 (a), 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern can be obtained no matter which part of the paper is taken 6 × 6 dots. Yes. The dot pattern formed by these 36 dots holds the position coordinates (for example, where the dot pattern is on the answer sheet 5). FIG. 5B is a diagram in which each dot shown in FIG. 5A is converted into a corresponding value based on 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 1 that captures an image of a dot pattern.

[Electronic pen]
Next, the electronic pen 1 will be described with reference to FIG. FIG. 6 is a schematic view showing the structure of the electronic pen 1. As shown in FIG. 6, the electronic pen 1 includes an ink cartridge 104, an LED 105, a CMOS camera 106, a pressure sensor 107, a processor 108 including a CPU, a memory 109 such as a ROM and a RAM, A communication unit 111 including a real time clock 110, an antenna, and the like, and a battery 112 are provided. The tip of the ink cartridge 104 is a pen tip portion 103, and each student touches the answer tip 5 with the pen tip portion 103 of the electronic pen 1 and enters a stroke (handwritten stroke). The ink of the ink cartridge 104 does not include a material that absorbs infrared rays (for example, carbon). Here, contact of the pen tip portion 103 of the electronic pen 1 with the paper is referred to as “pen down”, and removal of the pen tip portion 103 from the contact (contact) state is referred to as “pen up”. . A trajectory written between the pen-down and pen-up of the electronic pen 1 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes.

  The battery 112 is for supplying electric power to each component in the electronic pen 1. For example, the battery 112 is configured to turn on / off the electronic pen 1 itself by attaching and detaching a cap (not shown) of the electronic pen 1. May be. The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 108. The pressure sensor 107 detects the pressure applied through the ink cartridge 104 from the pen tip portion 103 when the student writes or taps letters or marks on the answer sheet 5 with the electronic pen 1, that is, the writing pressure. Is transmitted to the processor 108.

  The processor 108 switches on / off the switches of the LED 105 and the CMOS camera 106 based on the writing pressure data supplied from the pressure sensor 107. That is, when the student writes characters or the like on the answer sheet 5 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and when the pressure sensor 107 detects a writing pressure higher than a predetermined value, the processor 108 It is determined that the student has started entry, and the LED 105 and the CMOS camera 106 are operated. When the student finishes entering one stroke and releases the electronic pen 1 from the answer sheet 5, the pressure sensor 107 detects pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID and transmits it as entry information to the aggregation device 2.

  The LED 105 and the CMOS camera 106 are attached near the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion of the housing 101 that faces the LED 105 and the CMOS camera 106. The LED 105 illuminates infrared rays toward the vicinity of the pen tip portion 103 on the answer sheet 5. The region is slightly shifted from the position where the pen tip portion 103 contacts the answer sheet 5. The CMOS camera 106 is provided with an infrared transmission filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 captures a dot pattern in an area illuminated by the LED 105, and the image data of the dot pattern is captured. This is supplied to the processor 108. Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 105 are absorbed by the carbon contained in the dots. Therefore, the dot portion has a relatively small amount of infrared reflection, and the portion other than the dot has a relatively large amount of infrared reflection. By photographing with the CMOS camera 106, 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, even when an entry column or the like is printed on the answer sheet 5, the printed ink does not have an absorptivity in the infrared region, and thus the processor 108 can recognize the dot pattern. Note that the shooting area by the CMOS camera 106 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 106 is performed at regular intervals of about 50 to 100 times per second. Is called. Further, the CMOS camera 106 has a sufficient depth of field in order to photograph dots clearly.

  The processor 108 uses the dot pattern of the image data supplied by the CMOS camera 106 while the student's entry is performed, and the X and Y coordinates (hereinafter simply referred to as “X” and “Y” coordinates on the answer sheet 5 of the stroke (handwriting) to be entered by the student. (Also called “coordinate data” or “coordinate information”) is continuously calculated. That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 5A supplied by the CMOS camera 106 into the data array shown in FIG. The data is converted into a Y coordinate bit value, and X and Y coordinate data are calculated from the data array by a predetermined calculation method. The processor 108 has a rotation correction processing function for correcting the arrangement of dots on the image due to the angle of the electronic pen 1 facing the dot pattern, and is used for coordinate calculation. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, and X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. Since the 6 × 6 dot pattern in the answer sheet 5 does not overlap in the answer sheet 5, when the student enters characters or the like with the electronic pen 1, the entered position is any position on the answer sheet 5. Can be specified by coordinate calculation by the processor 108.

  The memory 109 stores property information such as pen IDs “pen01” to “pen05”, pen manufacturer numbers, and pen software versions for identifying the electronic pens 1A to 1E. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the aggregation device 2 as entry information. Transmission to the aggregation device 2 by the communication unit 111 is performed instantaneously and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the aggregation device 2 is stored as stroke information by the aggregation device 2. In other words, one stroke is composed of one or a plurality of X and Y coordinates (coordinate points), and the aggregation device 2 uses one or more of the pen-down information and the pen-up information to constitute one or a plurality of strokes. Recognize coordinate attribute information.

  As described above, each time the student enters the answer sheet 5, the electronic pens 1 </ b> A to 1 </ b> E generate entry information and transmit it to the aggregation device 2. In other words, the electronic pens 1 </ b> A to 1 </ b> E continue to generate entry information and transmit it to the aggregation device 2 while the student continues to fill in the answer sheet 5. When the student removes the electronic pen 1 from the answer sheet 5 (pens up), the electronic pen 1 does not detect a writing pressure exceeding a predetermined value by the pressure sensor 107, so that the student fills in. Determined to have stopped. In this case, the pen-up electronic pen 1 stops the LED 105 and the CMOS camera 106 and stops sending the entry information to the aggregation device 2.

  When the aggregation processing means 24 determines that the selected user display button 53 has been selected (step S105: selected user display), one student (operator is in the user selection list) in the upper area of the user stroke information display area 50. The stroke image entered by the student selected from 69) is enlarged and displayed in the lower area of the user stroke information display area 50 by the other student (the student not selected by the operator). The images are thumbnailed and displayed side by side (step S106). In this case, the aggregation processing unit 24 displays the stroke image generated in step S103 or S104.

  On the other hand, when the aggregation processing means 24 determines that the comparison list display button 54 has been selected (step S105: comparison list display), the stroke images entered by each student are displayed side by side at the same scale ( Step S107). In this case, the handwritten stroke image generation unit 241 of the aggregation processing unit 24 displays the stroke image generated in step S103 or S104.

  In the above description, the example in which the entry information generated in the cut-out time zone is extracted based on the time information (time stamp) included in the entry information has been described. However, the present invention is not limited to this. In another example, instead of the time information (time stamp), the entry information generated in the cut-out time zone based on the time when the aggregation device 2 and / or the transfer device 3 received the entry information from the electronic pen 1 is used. Can be extracted. In this example, the clock time in the aggregation device 2 and / or the transfer device 3 is used as the time at which entry information is received from the electronic pen 1, and such time is associated with the entry information received from the electronic pen 1. Thus, it is possible to determine whether the entry information is generated within the cut-out time zone.

  FIG. 18 is a flowchart showing processing performed in the selected user display. First, the aggregation processing unit 24 detects that any one of the thumbnails 201 displayed in the lower area is selected by an operator's mouse operation or the like (step S201). Then, the handwritten stroke image generation unit 241 of the aggregation processing unit 24 reduces the enlarged image 200 that is already displayed in the upper area, and enlarges the thumbnail 201 selected by the operator in the upper area (step S202). ). That is, the handwritten stroke image generation unit 241 of the aggregation processing unit 24 displays a list of the enlarged images 200 that have already been enlarged and displayed as thumbnails 201 and displays the thumbnail 201 selected by the operator as the enlarged image 200. In other words, the enlarged image 200 that has already been enlarged and the thumbnail 201 selected by the operator are exchanged.
