Description

  The present invention relates to a technique using a coding pattern readable by an electronic pen.

  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 Documents 2 and 3 disclose a system in which a dot pattern is stacked on an optical touch panel, and input using an electronic pen and touch panel input using a finger are possible. Non-Patent Document 1 has a configuration in which a liquid crystal is inserted and an electromagnetic induction type tablet is arranged at the bottom and a resistive film type touch panel is arranged at the top, allowing both input with an electronic pen and input with a finger. A touch panel is disclosed.

  Hereinafter, first to third embodiments, which are embodiments of the present invention, will be described in order with reference to the drawings.

<First Embodiment>
First, a first embodiment according to the present invention will be described.

[Configuration of input system]
FIG. 1 shows a configuration of an input system according to the first embodiment. As shown in FIG. 1, the input system includes an electronic pen 1 used by a user, a computer device 2 that receives and processes information from the electronic pen 1 and the display device 3, and a display device 3 connected to the computer device 2. And comprising. As will be described later, the input system is predetermined according to input based on the electronic pen 1 (also referred to as “electronic pen input”) and input based on the capacitive touch panel 34 (also referred to as “touch panel input”). Perform the process.

(Display device)
FIG. 2 shows a configuration of the display device 3 according to the first embodiment. As shown in FIG. 2, the display device 3 has a multilayer structure, and in order from the upper layer, a dot pattern overlayer (dot pattern forming layer) (also simply referred to as “DOL”) 30 and a capacitive touch panel 34. And a display panel 35.

  The DOL 30 is disposed on the uppermost layer of the display device 3. The DOL 30 is an ink containing a material (titanium oxide, cholesteric liquid crystal, infrared reflective pigment, etc.) that reflects infrared rays so that it can be read by the electronic pen 1 on a base film 33 that is a transparent resin substrate such as polyethylene terephthalate. Thus, a dot pattern (coded pattern) 32 is printed, and the layer structure is further protected by a protective layer 31 such as a transparent EB cured resin. Here, the dot pattern 32 is printed with a material that reflects infrared rays. Even when visible light of various colors is emitted from the display panel 35 below the DOL 30, the dot pattern 32 is printed with good contrast by the electronic pen 1. This is because it is desirable to recognize 32. The DOL 30 is an example of the “coded pattern layer” in the present invention.

  A capacitive touch panel 34 is bonded to the back surface of the DOL 30. The capacitive touch panel 34 detects a position by capturing a change in capacitance caused by pressing a finger on the DOL 30. The pen tip portion 103 of the electronic pen 1 is made of a material such as plastic or stainless steel, and the capacitance of the capacitive touch panel 34 does not change when the electronic pen 1 is touched or pressed on the DOL 30. Therefore, the capacitive touch panel 34 does not detect contact and pressing on the DOL 30 with the electronic pen 1.

  The configuration of the display device 3 to which the present invention is applicable is not limited to the configuration of FIG. Instead, the display device 2 is provided with an infrared reflective layer between the dot pattern 32 and the base film 33 or between the base film 33 and the capacitive touch panel 34, and the dot pattern 32 further includes It may be configured to print with ink containing carbon that absorbs infrared rays.

(Dot pattern)
Next, the dot pattern (coded pattern) 32 will be described with reference to FIGS. The dot pattern is based on the system of Anoto. FIG. 3 is a diagram for explaining the relationship between the dots of the dot pattern 32 and the values to which the dots are converted. As shown in FIG. 3, each dot of the dot pattern 32 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 virtual grid (the 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 DOL 30 are determined by the combination of the information thus associated.

  FIG. 4A shows an arrangement of a certain dot pattern 32. As shown in FIG. 4A, 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 where 6 × 6 dots are taken on DOL 30. . The dot pattern 32 formed by these 36 dots holds the position coordinates (for example, the position on the DOL 30 where the dot pattern 32 is located). FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a value associated with the regularity shown in FIG. 3 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 the dot pattern 32.

(Electronic pen)
Next, the electronic pen 1 will be described with reference to FIG. FIG. 5 is a schematic view showing the structure of the electronic pen 1. As shown in FIG. 5, the electronic pen 1 includes a pen unit 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 pen unit 104 is a pen point unit 103, and the user touches the pen point unit 103 of the electronic pen 1 on the DOL 30 and enters a stroke (handwritten stroke). Here, the pen tip portion 103 of the electronic pen 1 that first contacts the DOL 30 is referred to as pen-down, and the pen tip portion 103 leaving the contacted (contacted) 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 power to each component in the electronic pen 1, and is configured to turn on / off the power of the electronic pen 1 itself by, for example, detaching a cap (not shown) of the electronic pen 1. You may let them. 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 pen unit 104 from the pen point unit 103 when the user writes or taps a character or mark on the DOL 30 with the electronic pen 1, that is, the writing pressure, and the value is detected by the processor. To 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 a user writes a character or the like on the DOL 30 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 entry has started, and the LED 105 and the CMOS camera 106 are operated. Then, the communication unit 111 associates pen-down information detected by the pressure sensor 107 with identification information (hereinafter referred to as “pen ID”) of the electronic pen 1 described later, and transmits the information to the computer apparatus 2 as entry information. To do. When the user finishes entering one stroke and releases the electronic pen 1 from the DOL 30, 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 to the computer apparatus 2 as entry information.

  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 DOL 30. The region is slightly deviated from the position where the pen tip 103 contacts the DOL 30. The CMOS camera 106 is provided with an infrared filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 images a dot pattern 32 in an area illuminated by the LED 105, and image data of the dot pattern 32 is captured. Is supplied to the processor 108. Here, since the ink material of dots reflects infrared rays, the infrared rays irradiated by the LED 105 are reflected by the dots. Therefore, the dot portion has a relatively large amount of infrared reflection, and the portion other than the dot has a relatively small amount of infrared reflection. By photographing with the CMOS camera 106, a dot area and other areas can be distinguished by providing a threshold value based on the difference in the amount of reflected infrared light. 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. 4A, 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 performs X and Y coordinates (hereinafter simply referred to as “coordinate data”) in the DOL 30 of the stroke (handwriting) to be entered by the user from the dot pattern 32 of the image data supplied by the CMOS camera 106 during the user's entry. Or, it is also called “coordinate information”). That is, the processor 108 converts the image data of the dot pattern 32 as shown in FIG. 4A supplied by the CMOS camera 106 into the data array shown in FIG. Convert to Y coordinate bit value and calculate X, Y coordinate data from the data array by a predetermined calculation method. The processor 108 has a rotation correction processing function for correcting the arrangement of dots caused by the inclination of the electronic pen 1 facing the dot pattern. 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 32 in the DOL 30 does not overlap in the DOL 30, when the user enters characters or the like with the electronic pen 1, the processor determines which position in the DOL 30 the entered position corresponds to. It can be specified by coordinate calculation by 108.

  The memory 109 stores property information such as a pen ID such as “pen01” for identifying the electronic pen 1, a pen manufacturer number, and a pen software version. 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 computer apparatus 2 as entry information. Transmission to the computer apparatus 2 by the communication unit 111 is performed immediately 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 computer device 2 is stored as stroke information by the computer device 2. In other words, one stroke is made up of one or a plurality of X, Y coordinates (coordinate points), and the computer apparatus 2 can use one or a plurality of pieces constituting one stroke based on the pen-down information and the pen-up information. Recognize coordinate attribute information. As described above, a set of coordinate attribute information generated by the electronic pen 1 when the user enters one stroke is referred to as “stroke information”. The pen tip 103 is made of a material such as plastic or stainless steel. The pen tip portion 103 does not have ink, and transmits pen pressure to the pressure sensor 107 via the pen portion 104.

  The electronic pen 1 may be used as a ballpoint pen by loading an ink cartridge in the pen unit 104. In addition, the electronic pen 1 transmits entry information to the computer apparatus 2 by wireless transmission. However, the electronic pen 1 is not limited thereto, and may be connected to the computer apparatus 2 by wire and transmit entry information to the computer apparatus 2 by wire transmission. .

  In addition, preferably, when the CMOS camera 106 recognizes the dot pattern 32, the electronic pen 1 determines whether the dot pattern 32 is formed of an infrared reflecting material or an infrared absorbing material, and the determination is made. The dot pattern 32 reading program may be switched based on the above. Specifically, the electronic pen 1 first performs a binarization process on the image captured by the CMOS camera 106 using a predetermined threshold, and the infrared reflection region and the infrared absorption from the binarized image. The area is discriminated, and the magnitude relation between the area of the infrared reflection area and the area of the infrared absorption area is compared. The electronic pen 1 performs a negative / positive inversion process on the binarized image when the infrared absorption area is larger than the infrared reflection area, and performs a negative / positive inversion process when the negative / positive inversion process is performed. The dot pattern 32 is recognized based on the obtained image, and when the negative / positive inversion process is not performed, the dot pattern 32 is recognized based on the binarized image. Accordingly, it is possible to appropriately recognize both the dot pattern 32 printed with the infrared absorbing ink and the dot pattern 32 printed with the infrared reflective ink.

The computer device 2 includes, as hardware, an antenna device capable of data communication with the electronic pen 1, a processor such as a CPU, a memory such as a ROM and a RAM, a mouse and a keyboard.

As shown in FIG. 1, the computer device 2 functionally includes an input unit 21 such as a mouse and a keyboard, a reception unit 22, a processing unit 24, and a storage unit 25. The computer device 2 performs predetermined processing based on the entry information received from the electronic pen 1 and the input information received from the capacitive touch panel 34 (also referred to as “touch panel input information”).

  The receiving means 22 is constituted by an antenna receiving circuit or the like, receives entry information from the electronic pen 1 and transmits it to the processing means 24. Further, the computer apparatus 2 converts a coordinate system (also referred to as “DOL coordinate system”) related to the dot pattern 32 formed on the DOL 30 into a coordinate system (also referred to as “display coordinate system”) related to the display panel 35. Calibration for obtaining a first coordinate conversion function for converting the coordinate system (also referred to as “touch panel coordinate system”) applied to the capacitive touch panel 34 to a display coordinate system. It has a processing function. Furthermore, when the computer apparatus 2 receives the data of the DOL coordinate system using the first coordinate conversion function obtained by the calibration process, the computer apparatus 2 converts the data into the data of the display coordinate system and draws a stroke. When touch panel coordinate system data is received using a function for performing a predetermined process and the second coordinate conversion function, the data is converted into display coordinate system data, and predetermined processes such as icon selection are performed. It has a function.

  The processing means 24 is constituted by a processor such as a CPU and controls the entire computer apparatus 2. Specifically, the processing unit 24 transmits the image signal generated by the computer apparatus 2 to the display panel 35 and displays an image corresponding to the image signal. The processing unit 24 stores the first coordinate conversion function and the second coordinate conversion function obtained by the calibration processing function in the storage unit 25.

  When the computer device 2 receives the entry information from the electronic pen 1, the first coordinate conversion means 241 of the processing means 24 converts the coordinate data included in the entry information, which is DOL coordinate system data, into a first coordinate conversion function. To convert to display coordinate system data. Then, the processing means 24 recognizes that the position written by the electronic pen 1 is the dot pattern 32 of the DOL 30 based on the converted coordinate data. The processing unit 24 stores the converted coordinate data in the storage unit 25, displays a stroke based on the converted coordinate data or the like on the display panel 35, or displays a folder or application at a position corresponding to the stroke. If the icon is displayed, processing such as selection of the icon is performed.

  When the computer apparatus 2 receives touch panel input information from the capacitive touch panel 34, the second coordinate conversion unit 242 of the processing unit 24 converts the coordinate data of the touch panel coordinate system included in the touch panel input information to the second coordinate conversion. Use functions to convert to display coordinate system data. Then, when an icon such as a folder or an application is displayed in the coordinate data after conversion, the processing unit 24 performs processing such as selection of the icon. When the second coordinate conversion unit 242 determines that the entry information has been received by determining whether the entry information has been received from the electronic pen 1 for a predetermined time width after receiving the touch panel input information. In this case, the touch panel input information is discarded without being converted into display coordinate system data. The predetermined time width is determined, for example, by previously obtaining a time difference (time lag) until detection of each input when the input with the electronic pen 1 and the touch panel input are simultaneously performed by an experiment or the like.

  The storage unit 25 is configured by a memory such as a ROM or a RAM. The storage means 25 stores the first coordinate conversion function and the second coordinate conversion function. In addition, the storage unit 25 stores the entry information received from the electronic pen 1 for each pen ID or the predetermined data generated by the execution of the program according to the processing instruction of the processing unit 24.

[Operational effects of the input system of the first embodiment]
According to the input system of the first embodiment, the display device 3 includes the DOL 30 and the capacitive touch panel 34, and even when the pen tip portion 103 of the electronic pen 1 is in contact with the display, the display device 3 has a capacitance. Since there is no influence, the capacitive touch panel 34 does not detect touch panel input. Therefore, the display device 3 can distinguish input from the electronic pen 1 from input to the capacitive touch panel by a finger. Therefore, the input system can appropriately recognize the electronic pen input and the touch panel input by the user's finger.

[Modification of First Embodiment]
Next, a modification of the first embodiment will be described. The following modifications may be applied in any combination to the first embodiment described above.

(Modification 1)
1 and 2, the DOL 30 and the capacitive touch panel 34 are stacked on the display panel 35. However, the configuration of the input system to which the present invention is applicable is not limited to this.

  FIG. 6 is a system configuration diagram of an input system according to the first modification of the first embodiment. As shown in FIG. 6, the input system according to the first modification of the first embodiment includes a projector 4 that projects the same image as the display screen of the display of the computer device 2 onto the DOL 30. Further, the DOL 30 and the capacitive touch panel 34 are stacked and disposed at a position away from the display of the computer device 2. Further, the capacitive touch panel 34 is connected to the computer device 2 and transmits touch panel input information to the computer device 2. Although the projector 4 shown in FIG. 6 is a front projector, it may be a rear projector. In addition, an imaging diffusion layer for imaging and diffusing the projected light may be adopted as a layer constituting the DOL 30 or the touch panel 34, or an imaging diffusion layer may be laminated separately from the DOL 30 and the touch panel 34.

  As described above, even if the DOL 30 and the capacitive touch panel 34 are not stacked on the display, the processing unit 24 of the computer apparatus 2 may use the coordinates of the DOL coordinate system included in the entry information received from the electronic pen 1. The information is converted into coordinate information of the display coordinate system using the first coordinate conversion function stored in the storage unit 25. Further, the processing unit 24 uses the second coordinate transformation function stored by the entry unit 25 to convert the coordinate information of the touch panel coordinate system included in the touch panel input information received from the capacitive touch panel 34 into the display coordinate system. Convert to coordinate information. By doing in this way, the input system can receive electronic pen input and touch panel input by a user's finger suitably, and can recognize each appropriately.

(Modification 2)
In the first embodiment, the Anoto coding pattern (dot pattern) is used. However, any coding pattern indicating position coordinates may be used, and the Anoto coding is not limited.

Second Embodiment
Next, a second embodiment will be described. FIG. 7 is a system configuration diagram of an input system according to the second embodiment. In the second embodiment, the processing unit 24 is different from the first embodiment in that the processing unit 24 further includes a touch panel function switching unit 243 that switches on and off an input function of the capacitive touch panel 34. In addition, about the part similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably.

  The touch panel function switching unit 243 of the processing unit 24 turns off the input function by the capacitive touch panel 34 while the computer apparatus 2 receives the entry information from the electronic pen 1. In this case, the touch panel function switching unit 243 transmits a control signal to the capacitive touch panel 34 so that the capacitive touch panel 34 is stopped while receiving the entry information from the electronic pen 1. Alternatively, the touch panel input information transmitted from the capacitive touch panel 34 may be discarded without being processed by the processing means 24 during the period. On the other hand, when the computer apparatus 2 has not received entry information from the electronic pen 1, the touch panel function switching unit 243 turns on the input function of the capacitive touch panel 34. That is, in this case, the processing unit 24 performs the same processing as in the first embodiment.

[Processing flow]
Next, a processing flow based on input by the electronic pen 1 in the input system according to the second embodiment will be described. The processing flow shown in FIG. 8 is repeatedly executed every time entry information is generated by the electronic pen 1.

  When the user enters characters or the like on the DOL 30 with the electronic pen 1, the electronic pen 1 transmits the entry information associated with the pen down information and the pen ID to the computer device 2 at the time of the pen down. In addition, during the entry of the stroke, the electronic pen 1 transmits to the computer device 2 entry information in which the coordinate attribute information including the coordinate information calculated by imaging the dot pattern 32 along the stroke and the pen ID is associated. To do. Then, at the time of pen-up, the electronic pen 1 transmits entry information associated with pen-up information and a pen ID to the computer device 2 (step S101).

  In the computer apparatus 2, when the receiving unit 22 receives the entry information transmitted from the electronic pen 1, the processing unit 24 causes the storage unit 25 to store the entry information for each pen ID (step S201). Next, the processing means 24 determines whether or not the input function of the capacitive touch panel 34 has already been turned off (step S202). If it is determined that the input function of the capacitive touch panel 34 is on (step S202; No), the input function of the capacitive touch panel 34 is turned off (step S203). On the other hand, when it is determined that the input function of the capacitive touch panel 34 is already off (step S202; Yes), the processing unit 24 does not perform the process of step S203 and maintains the off state, step S204. Proceed to the process.

  Next, the processing means 24 converts the coordinate information of the DOL coordinate system included in the received entry information into the coordinate information of the display coordinate system using the first coordinate conversion function stored in the storage means 25 (step S204). Then, the processing means 24 performs electronic pen input processing (step S205). For example, based on the converted coordinate information, the processing unit 24 draws the stroke that has been entered on the image that is currently displayed by the display panel 35, and updates the display on the display panel 35. The image is updated and stored in the storage means 25.

  Next, the processing means 24 determines whether or not entry information has been received from the electronic pen 1 (step S206). If it is determined that the entry information has been received (step S206; Yes), the processing unit 24 continues the process of step S201 and performs the process based on the entry information. On the other hand, if it is determined that the entry information has not been received (step S206; No), the processing unit 24 turns the input function of the capacitive touch panel 34 back on (step S207). And the process means 24 complete | finishes the process of a flowchart.

[Operational effects of the input system of the second embodiment]
According to the input system of the second embodiment, the computer device 2 turns off the input function of the capacitive touch panel 34 while the input with the electronic pen 1 is being performed. Thereby, the computer apparatus 2 can prevent erroneous detection of touch panel input even when a finger or a palm touches the display unintentionally during input with the electronic pen 1. Further, the computer device 2 switches on / off the input function of the capacitive touch panel 34 based on whether or not the entry information of the electronic pen 1 is received. Thereby, the input system can prevent erroneous input of touch panel input while minimizing the period during which touch panel input is disabled.

[Modification of Second Embodiment]
Next, a modification of the second embodiment will be described. In the second embodiment, the modified example of the first embodiment can be applied in any combination.

<Third Embodiment>
Next, a third embodiment will be described. FIG. 9 is a system configuration diagram of an input system according to the third embodiment. In the third embodiment, the processing unit 24 is different from the first embodiment in that the processing unit 24 further includes a touch panel function limiting unit 244 that limits the period and range of invalidating the touch panel input. In addition, about the part similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably.

  The touch panel function restriction unit 244 of the processing unit 24 is within a predetermined range from the pen tip position (also referred to as “electronic pen input position”) of the electronic pen 1 while the computer apparatus 2 receives the entry information from the electronic pen 1. The input function of the capacitive touch panel 34 is turned off. Then, when the electronic pen input position changes, the processing unit 24 determines a range in which the input function of the capacitive touch panel 34 is turned off based on the changed electronic pen input position. Hereinafter, the range in which the input function of the capacitive touch panel 34 is turned off based on the input position of the electronic pen is also referred to as a “restricted range Wr”.

  Specific processing of the touch panel function limiting unit 244 will be further described with reference to FIG. FIG. 10 is an example of a display screen of the display device 3 in the third embodiment.

  In FIG. 10, the user touches the pen tip portion 103 of the electronic pen 1 on the DOL 30. In this case, the processing unit 24 converts the coordinate data included in the entry information received from the electronic pen 1 into coordinate data in the display coordinate system using the first coordinate conversion function, and the position of the coordinate data is converted to the electronic pen. Determine the input position. Then, the processing unit 24 determines a circular area with a radius R centered on the electronic pen input position as the limit range Wr, turns off the input function of the capacitive touch panel 34 in the limit range Wr, and other than the limit range Wr The input function of the capacitive touch panel 34 in the area is turned on. Specifically, while receiving the entry information from the electronic pen 1, the processing unit 24 converts the coordinate data of the touch panel coordinate system included in the touch panel input information transmitted from the capacitive touch panel 34 to the second coordinate. When the converting means 242 converts the data into the display coordinate system using the second coordinate conversion function, it is determined whether or not the converted coordinate data is included in the limit range Wr. If it is determined that the coordinate data is included in the limited range Wr, the processing unit 24 discards the coordinate data without performing touch panel input processing. On the other hand, when it is determined that the coordinate data is not included in the restriction range Wr, the processing unit 24 performs touch panel input processing. In addition, the above-mentioned radius R is good to set to 10-15 cm, for example. Specifically, when performing input with the electronic pen 1 on the DOL 30, the maximum distance from the electronic pen input position to a position where the side portion of the hand holding the electronic pen 1 may contact on the DOL 30 Is determined in advance through experiments or the like, and the radius R is determined as the maximum distance.

  In addition, when the electronic pen input position changes, the processing unit 24 newly sets a limit range Wr based on the changed electronic pen input position, and turns off the input function of the capacitive touch panel 34 in the range. To. Therefore, while the stroke is drawn by the electronic pen 1, the limit range Wr also moves as the electronic pen input position moves. Further, when receiving the entry information from the plurality of electronic pens 1, the processing unit 24 provides a limit range Wr corresponding to each electronic pen 1. Specifically, in this case, the processing unit 24 specifies each electronic pen input position based on the entry information of each electronic pen 1 and determines the limit range Wr based on the electronic pen input position. In this case, the limited range Wr is an area on the DOL 30 that is a combination of circular areas with a radius R centered on each electronic pen input position.

[Processing flow]
Next, a processing flow based on input by the electronic pen 1 in the input system according to the third embodiment will be described. The processing flow shown in FIG. 11 is repeatedly executed each time entry information is generated by the electronic pen 1. The process flow shown in FIG. 11 is executed in parallel for each electronic pen 1 when entry information is generated by a plurality of electronic pens 1 at the same time.

  When the user enters characters or the like on the DOL 30 with the electronic pen 1, the electronic pen 1 transmits the entry information associated with the pen down information and the pen ID to the computer device 2 at the time of the pen down. In addition, during the entry of the stroke, the electronic pen 1 transmits to the computer device 2 entry information in which the coordinate attribute information including the coordinate information calculated by imaging the dot pattern 32 along the stroke and the pen ID is associated. To do. Then, at the time of pen-up, the electronic pen 1 transmits entry information associated with pen-up information and a pen ID to the computer device 2 (step S301).

  In the computer apparatus 2, when the receiving unit 22 receives the entry information transmitted from the electronic pen 1, the processing unit 24 causes the storage unit 25 to store the entry information for each pen ID (step S401). Next, the processing means 24 converts the coordinate information of the DOL coordinate system included in the received entry information into the coordinate information of the display coordinate system using the first coordinate conversion function stored in the storage means 25 (step S402). Then, the processing means 24 determines the electronic pen input position based on the converted coordinate information, and turns off the input function of the capacitive touch panel 34 within a predetermined range from the electronic pen input position (step S403). Specifically, the processing unit 24 determines a circular area having a radius R from the electronic pen input position as the limit range Wr. Then, the processing means 24 performs electronic pen input processing (step S404).

  Next, the processing means 24 determines whether or not entry information is continuously received from the same electronic pen 1 as the electronic pen 1 subjected to the electronic pen input processing in step S404 (step S405). If it is determined that entry information has been received from the same electronic pen 1 as the target electronic pen 1 (step S405; Yes), the processing unit 24 proceeds to the process of step S401, and based on the entry information. Process. On the other hand, when it is determined that the entry information has not been received from the same electronic pen 1 as the target electronic pen 1 (step S405; No), the processing unit 24 performs static based on the electronic pen input position of the target electronic pen 1. The restriction on the input function of the capacitive touch panel 34 is released (step S406). Note that when there is another electronic pen 1 that has received the entry information, the processing unit 24 continues from the electronic pen input position of the other electronic pen 1 to a circular area having a radius R (restriction range Wr). The input function of the capacitive touch panel 34 is turned off. And the process means 24 complete | finishes the process of a flowchart.

[Operational effects of the input system of the third embodiment]
According to the input system of the third embodiment, the computer device 2 turns off the input function of the capacitive touch panel 34 in a predetermined range from the electronic pen input position while the input with the electronic pen 1 is being performed. Thereby, the input system can prevent an erroneous input caused by an unintentional contact of the side of the hand holding the electronic pen 1 with the display while the electronic pen 1 is inputting. Further, the computer device 2 turns off the input function of the capacitive touch panel 34 only within a predetermined range based on the input position of the electronic pen, so that the side portion of the hand holding the electronic pen 1 contacts the display. In addition, it is possible to effectively process an intended touch panel input by a finger of one hand or another user's hand while preventing erroneous input due to the above. Therefore, the third embodiment is also suitably applied when the display device 3 has a large screen and a touch panel input is performed by a plurality of people.

[Modification of Third Embodiment]
Next, a modification of the third embodiment will be described. In the third embodiment, the modification example of the first embodiment and the modification examples described below can be applied in any combination.

(Modification 3)
In the description of FIG. 10, the processing unit 24 defines the circular area having the radius R from the electronic pen input position as the limited range Wr, but the setting method of the limited range Wr is not limited thereto. Instead of this, for example, the processing means 24 may determine an area of a predetermined shape other than an ellipse or other circles as the limit range Wr based on the electronic pen input position. At this time, it is preferable that the area opposite to the dominant hand of the user who uses the electronic pen 1 is not limited. The dominant hand of the user may be stored in the storage unit 25 in association with the pen ID of the electronic pen 1 used in advance, or the electronic pen 1 is provided with an angle sensor or the distortion of the dot pattern 32 taken by the electronic pen 1. You may make it determine by calculating | requiring the inclination of the electronic pen 1 from a shape, and including inclination information in entry information (the side where the electronic pen 1 inclines is dominant).
