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. Further, Patent Document 4 discloses an electronic pen that is provided with a proximity sensor and can specify that the electronic pen is approaching or in contact with the writing surface based on a detection signal of the proximity sensor. .

  Further, Patent Document 5 discloses a knock-type composite writing instrument that has a ballpoint pen and a mechanical pencil, and of which a pen tip that protrudes from a tip end can be switched by a knocking operation. Similarly, Patent Document 6 discloses a knock-type composite writing instrument.

  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.

Pushes the knock operation portion 129 in the direction of the slit portion 122. As a result, the end of the stopper 125 is detached from the groove 128. Therefore, in this case, due to the restoring force of the spring 120, the knock operation portion 129 is urged in the direction opposite to the pen tip direction and moves along the stopper 125, and the pen tip portion 103 is moved into the pen portion side casing 101A. Is stored (also simply referred to as “stored state”). Similarly, when an operation (knock operation) for pushing the protrusion 121 in the pen tip direction is performed when the pen tip portion 113 is in the protruding state, the raised portions 123 and 124 of the knock operation portion 129 cause the knock operation portion 139 to move. Extrusion in the direction of the slit portion 132. As a result, the end of the stopper 125 is detached from the groove 138. Therefore, in this case, the knock operation portion 139 is urged in the direction opposite to the pen tip direction by the restoring force of the spring 130 and moves along the stopper 125, and the pen tip portion 113 enters the retracted state.

  As described above, the electronic pen 1 is in a state in which the pen tip portion 103 of the electronic pen portion 104 is in a protruding state and the pen tip portion 113 of the touch panel pen portion 114 is in a retracted state (first state) by a knocking operation. A state in which the pen tip 103 is stored and the pen tip 113 is in a protruding state (second state), or a state in which the pen tip 103 is stored and the pen tip 113 is stored (third state). ) To switch to either state. The knock operation units 129 and 139, the springs 120 and 130, and the stopper 125 are examples of the “pen tip transition mechanism” in the present invention.

  Next, the electronic pen unit 104 will be specifically described. The tip of the electronic pen unit 104 is a pen point unit 103 formed of a material such as plastic or stainless steel, and the user brings the pen point unit 103 of the electronic pen unit 104 into contact with the entry sheet 4, Enter a stroke (handwritten stroke). Here, the first contact of the pen tip portion 103 with the entry sheet 4 is referred to as “pen down”, and the 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 pen tip portion 103 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes. Preferably, an ink cartridge is loaded inside the electronic pen unit 104. Thereby, the electronic pen unit 104 also functions as a ballpoint pen, and after writing on the entry sheet 4, the entry contents can be visually recognized on the entry sheet 4.

  Further, the electronic pen unit 104 is provided with a pressure sensor 107. The pressure sensor 107 is a pressure transmitted from the pen tip portion 103 when the user causes the pen tip portion 103 to protrude from the opening portion 102 and writes or taps characters or marks on the entry sheet 4 or the like, that is, writing pressure. Is detected and the value is transmitted to the processor 108 described later.

  Next, the touch panel pen unit 114 will be described. The pen point portion 113 of the touch panel pen portion 114 has a structure that can be detected by the touch panel. Specifically, when the touch panel laminated on the display device 3 is a capacitive type, the touch panel pen unit 114 is formed of a conductive material. On the other hand, when the touch panel is an electromagnetic induction system, a coil and a resonance circuit are built in the touch panel pen unit 114.

  Next, each element placed on the substrate 100 will be described with reference to FIG. The substrate unit 100 is mainly provided with a processor 108 constituted by an LED 105, a CMOS camera 106, a CPU, etc., a memory 109 such as ROM and RAM, a real time clock 110, a communication unit 111 constituted by an antenna and the like.

  The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information 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 user writes a character or the like on the entry sheet 4 with the pen tip portion 103 of the electronic pen portion 104 protruding, a pen pressure is applied to the pen tip portion 103 and the pressure sensor 107 applies a writing pressure of a predetermined value or more. When detected, the processor 108 determines that the user has begun entry and activates the LED 105 and the CMOS camera 106. 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 moves the pen tip portion 103 of the electronic pen unit 104 away from the entry sheet 4, the pressure sensor 107 detects pen-up because the writing pressure exceeding a predetermined value is not detected. To do. 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 in the vicinity of the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion facing the LED 105 and the CMOS camera 106 in the pen portion casing 101 </ b> A. The LED 105 illuminates infrared rays toward the vicinity of the pen tip portion 103 on the entry sheet 4. The region is slightly shifted from the position where the pen tip portion 103 contacts the entry sheet 4. 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 the ink material of the dots on the entry sheet 4 absorbs infrared rays, the infrared rays irradiated by the LED 105 are absorbed by 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 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. 3A, 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. 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”) on the entry sheet 4 of the stroke (handwriting) to be entered by the user from the dot pattern of the image data supplied by the CMOS camera 106 while the user performs the entry. Or “coordinate information”) is continuously calculated. That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 4 (a) supplied by the CMOS camera 106 into the data array shown in FIG. 4 (b). 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 on the entry sheet 4 does not overlap in the entry sheet 4, when the user enters characters or the like with the electronic pen 1, the entered position is any position in the entry sheet 4. Can be specified by coordinate calculation by the processor 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.

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. The computer device 2 may be configured by a PC (personal computer) including the display device 3 as a display unit, a tablet PC such as iPad (registered trademark), a PDA (Personal Data Assistance), or the like. Then, the computer device 2 performs a predetermined process based on the entry information received from the electronic pen 1 and the input information (also referred to as “touch panel input information”) received from the touch panel stacked on the display device 3.

[Operational effects of the input system of the first embodiment]
According to the input system of the first embodiment, the electronic pen 1 is configured so that the pen point portion 103 of the electronic pen unit 104 protrudes from the opening 102 and the pen point of the touch panel pen unit 114 based on a user's knocking operation. Switching between the state in which the portion 113 protrudes from the opening 102 is possible. Therefore, the user can appropriately execute both the touch panel input and the electronic pen input with one electronic pen 1.

[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.

And transition to the third state. As described above, even when the pen tip portions 103 and 113 protruding from the opening 102 are switched by the rotation operation of the pen unit side casing 101A, both the touch panel input and the electronic pen input are preferably performed by the electronic pen 1. Can be executed.

(Modification 2)
In the first embodiment, the method of electronic pen, coding pattern (dot pattern), and entry information is not limited to the Anoto method.

Second Embodiment
Next, a second embodiment will be described. FIG. 8 shows the configuration of the input system according to the second embodiment. In the input system according to the second embodiment, the electronic pen 1 mainly transmits a point where a layer on which a dot pattern is formed is stacked on the display device 3 and on / off of a touch panel function of the display device 3. The electronic pen unit 104 differs from the input system of the first embodiment in that the electronic pen unit 104 is switched based on a signal indicating the state of the pen point unit 103. In addition, about the part similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably.

  As shown in FIG. 8, the input system according to the second embodiment 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 computer device 2. And a connected display device 3. As will be described later, the input system performs predetermined processing according to electronic pen input and touch panel input.

(Display device)
FIG. 9 shows a configuration of the display device 3 according to the second embodiment. As shown in FIG. 9, 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, a 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. In this way, dots 32 of a dot pattern (coded pattern) are printed, and the layer structure is further protected by a protective layer 31 such as a transparent EB cured resin. Here, the dot pattern is printed with a material that reflects infrared rays. Even when visible light of various colors is radiated from the display panel 35 under the DOL 30, the dot pattern is formed with high contrast by the electronic pen 1. This is because it is desirable for recognition. The DOL 30 is an example of the “coded pattern layer” in the present invention.

  A touch panel 34 is bonded to the back surface of the DOL 30. The touch panel 34 detects a contact position on the DOL 30. The touch panel 34 is, for example, a resistive touch panel, an ultrasonic touch panel, an optical touch panel, a capacitive touch panel, or the like.

  The configuration of the display device 3 to which the present invention is applicable is not limited to the configuration of FIG. Instead of this, the display device 3 is provided with an infrared reflective layer between the dot pattern and the base film 33 or between the base film 33 and the touch panel 34, and the dot pattern further absorbs carbon that absorbs infrared rays. The configuration may be such that printing is performed with the contained ink.

  Further, when the touch panel 34 is a capacitive touch panel, the dots 32 of the DOL 30 are made of a material having no conductivity or a material having a low conductivity so as not to affect the capacitance detected by the touch panel 34. Composed. Thereby, the change of the electrostatic capacitance with respect to the touch panel input by the touch panel pen unit 114 of the electronic pen 1 can be easily captured.

(Electronic pen)
Next, the structure of the electronic pen 1 according to the second embodiment will be described. FIG. 10 is an example of a cross-sectional view of the electronic pen 1 according to the second embodiment corresponding to FIG.

  As shown in FIG. 10, the electronic pen 1 includes a knock detection unit 140. The knock detection unit 140 detects whether the pen tip portion 103 of the electronic pen unit 104 has changed to the protruding state or the stored state by a knock operation to the knock operation units 129 and 139. For example, when a knocking operation that changes the state of the pen tip unit 103 is performed, the knock detection unit 140 detects the movement of the pressure sensor 107, so that the pen tip unit 103 transitions to either the protruding state or the retracted state. Detect if you did. Then, knock detection unit 140 transmits a detection signal (also referred to as “pen-tip state detection signal Sd”) indicating whether or not pen-tip unit 103 is in the protruding state to processor 108. Then, the processor 108 transmits the pen tip state detection signal Sd to the computer apparatus 2 through the communication unit 111.

Preferably, when the CMOS camera 106 recognizes the dot pattern, the electronic pen 1 determines whether the dot pattern is formed of an infrared reflecting material or an infrared absorbing material, and based on the determination. The dot pattern reading program may be switched. 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 is recognized based on the obtained image, and when the negative / positive inversion process is not performed, the dot pattern is recognized based on the binarized image.
Thereby, it is possible to appropriately recognize both the dot pattern printed with the infrared absorbing ink and the dot pattern printed with the infrared reflective ink.

(Computer device)
Next, the computer apparatus 2 of the second embodiment will be described again with reference to FIG. As shown in FIG. 8, the computer apparatus 2 according to the second embodiment 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 touch panel input information received from the touch panel 34.

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 the coordinate system (also referred to as “DOL coordinate system”) related to the dot pattern formed on the DOL 30 to the coordinate system (also referred to as “display coordinate system”) related to the display panel 35. Calibration processing functions for obtaining the first coordinate conversion function and the second coordinate conversion function for converting the coordinate system (also referred to as “touch panel coordinate system”) applied to the touch panel 34 to the display coordinate system. ing. 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.

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 unit 24 recognizes that the position written by the electronic pen 1 is the dot pattern 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 touch panel 34, the second coordinate conversion unit 242 of the processing unit 24 uses the second coordinate conversion function to convert the coordinate data of the touch panel coordinate system indicated by the touch panel input information, using the second coordinate conversion function. Convert to display coordinate system data. Then, when an icon such as a folder or an application is displayed on the coordinate data after conversion in the image being displayed on the display panel 35, the processing means 24 performs processing such as selection of the icon.

  The touch panel function switching unit 243 of the processing unit 24 switches on / off of the input function of the touch panel 34 based on the pen tip state detection signal Sd received by the receiving unit 22 from the electronic pen 1. Specifically, the touch panel function switching unit 243 turns off the input function of the touch panel 34 when the pen tip state detection signal Sd indicates that the pen tip part 103 of the electronic pen unit 104 is in a protruding state. That is, in this case, the touch panel function switching unit 243 determines that the electronic pen input is highly likely to be performed, and gives priority to the electronic pen input to prevent erroneous input to the touch panel 34. At this time, the touch panel function switching unit 243 may transmit a control signal to the touch panel 34 so that the touch panel 34 is stopped, or from the touch panel 34 while the input function of the touch panel 34 is turned off. The touch panel input information to be transmitted may be discarded without being processed by the processing means 24.

  On the other hand, when the pen tip state detection signal Sd indicates that the pen tip portion 103 of the electronic pen unit 104 is stored in the pen unit casing 101A, the touch panel function switching unit 243 has an input function of the touch panel 34. Turn on. While the input function of the touch panel 34 is on, the processing unit 24 performs a predetermined process based on the touch panel input information received from the touch panel 34 when there is a touch panel input.

  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.

[Processing flow]
Next, a processing flow executed by the computer apparatus 2 in the input system according to the second embodiment will be described. FIG. 11 is a flowchart illustrating a processing flow executed by the computer apparatus 2 in the second embodiment. The processing flow shown in FIG. 11 is repeatedly executed according to a predetermined cycle, for example.

  When the user performs a knocking operation to change the state of the pen tip portion 103, the electronic pen 1 detects the movement of the pen tip portion 103 of the electronic pen portion 104 by the knock detection portion 140 (step S101). Then, the electronic pen 1 transmits the pen tip state detection signal Sd generated by the knock detection unit 140 to the computer device 2 (step S102).

  In the computer apparatus 2, when the receiving unit 22 receives the pen tip state detection signal Sd transmitted from the electronic pen 1 (step S201), the processing unit 24 uses the electronic pen unit based on the received pen tip state detection signal Sd. It is determined whether or not the pen point 103 of 104 has transitioned to a protruding state protruding from the opening 102 (step S202). When the pen point portion 103 of the electronic pen unit 104 is in the protruding state (step S202; Yes), the touch panel function switching unit 243 of the processing unit 24 turns off the input function of the touch panel 34 (step S203). Thereby, when it is estimated that the electronic pen input is likely to be performed, the computer apparatus 2 gives priority to the electronic pen input and prevents erroneous input to the touch panel 34.

  On the other hand, when the pen point portion 103 of the electronic pen unit 104 is not in the protruding state (step S202; No), the processing unit 24 stores the pen point portion 103 of the electronic pen unit 104 stored in the pen unit side housing 101A. (Step S204). Then, the touch panel function switching unit 243 of the processing unit 24 turns on the input function by the touch panel 34 (step S205). Then, when there is a touch panel input, the processing unit 24 performs a predetermined process based on the touch panel input information received from the touch panel 34.

[Operational effects of the input system of the second embodiment]

When the state change of the pen tip portion 103 of the electronic pen unit 104 based on the knock operation is detected, the electronic pen 1 A pen tip state detection signal Sd is transmitted. If the computer device 2 determines that the pen tip portion 103 of the electronic pen portion 104 is in the protruding state based on the received pen tip state detection signal Sd, the computer device 2 turns off the input function of the touch panel 34. In this way, the input system can prioritize electronic pen input and prevent erroneous input on the touch panel 34 when there is a high possibility that electronic pen input will be performed. Therefore, the input system detects erroneous touch panel input due to the pen tip portion 103 of the electronic pen unit 104 coming into contact with the DOL 30 during electronic pen input, or a hand that holds the electronic pen 1 during electronic pen input. It is possible to prevent erroneous detection of touch panel input and the like due to the side portion or the like touching the DOL 30.

[Modification of Second Embodiment]
Next, a modification of the second embodiment will be described. In the second embodiment, in addition to Modification 1 and Modification 2 of the first embodiment, the following Modification 3 and Modification 4 can be arbitrarily combined and applied.

The part 151 rotates together with the shaft part 150 in the direction of the arrow “Y1”. In this case, the knock detection unit 140 that is a rotary switch detects that the electronic pen unit 104 is in a protruding state based on the state (phase) of the shaft unit 150. On the other hand, when the touch panel pen unit 114 is moved in the pen tip direction by the knocking operation, the portion where the hole 153 of the 8-shaped rotating unit 151 is formed is pushed out by the nut-shaped member 156 in the pen-tip direction, The moving part 151 rotates together with the shaft part 150 in the direction of the arrow “Y2”. In this case, the knock detection unit 140 detects that the touch panel pen unit 114 is in the protruding state and the electronic pen unit 104 is in the retracted state based on the state (phase) of the shaft unit 150. When the electronic pen unit 104 and the touch panel pen unit 114 are both stored, the 8-shaped rotating unit 151 and the shaft unit 150 are in an equilibrium state in which neither the arrow Y1 nor the arrow Y2 is inclined. It becomes. In this case, the knock detection unit 140 detects that the pen tip portion 113 of the touch panel pen portion 114 and the pen tip portion 103 of the electronic pen portion 104 are both stored based on the phase of the shaft portion 150.

  In another example, knock detection unit 140 may be a strain gauge. In this case, knock detection unit 140 is provided on a conductor (not shown) that connects pressure sensor 107 and processor 108 of substrate 100. The knock detection unit 140 detects a change in the distortion (expansion / contraction) of the conductive wire based on the movement of the electronic pen unit 104 in the pen tip direction and the opposite direction, and the protruding state of the pen tip unit 103 of the electronic pen unit 104 and Detect the storage state.

(Modification 4)
In FIGS. 8 and 9, the DOL 30 and the 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. 13 is a system configuration diagram of an input system according to Modification 4 of the second embodiment. As illustrated in FIG. 13, the input system according to the fourth modification of the second embodiment includes a projector 6 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 touch panel 34 are stacked and disposed at a position away from the display of the computer apparatus 2. The touch panel 34 is connected to the computer device 2 and transmits touch panel input information to the computer device 2. The projector 6 shown in FIG. 13 is a front projector, but 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 when the DOL 30 and the touch panel 34 are not stacked on the display, the processing unit 24 of the computer apparatus 2 stores the coordinate information of the DOL coordinate system included in the entry information received from the electronic pen 1. Using the first coordinate conversion function stored by the means 25, it is converted into coordinate information of the display coordinate system, and input processing of the electronic pen 1 is performed. The processing unit 24 converts the touch panel coordinate system coordinate information indicated by the touch panel input information received from the touch panel 34 into coordinate information of the display coordinate system using the second coordinate conversion function stored by the entry unit 25, Input processing of the touch panel 34 is performed. Furthermore, the electronic pen 1 generates a pen tip state detection signal Sd based on the user's knocking operation and transmits it to the computer device 2. The processing unit 24 switches the input function of the touch panel 34 on and off based on the received pen tip state detection signal Sd.

  Also with this configuration, the input system preferably processes electronic pen input and touch panel input, restricts the input function of the touch panel 34 at any timing of the user, and prevents erroneous input of the touch panel 34. it can.

<Third Embodiment>
Next, a third embodiment will be described. FIG. 14 is a system configuration diagram of an input system according to the third embodiment. In the third embodiment, there are a plurality of electronic pens 1 that perform input to the display device 3, and instead of the touch panel function switching unit 243, a touch panel function limiting unit 244 that limits a period and a range in which the touch panel input is valid is provided. And while the pen point part 103 of the electronic pen part 104 is in the protruding state, the LED 105 and the CMOS camera 106 are always set to be on, which is different from the second embodiment. In addition, about the part similar to 2nd Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably.

  In the third embodiment, the processor 108 of the electronic pen 1 causes the pen tip portion 103 to protrude based on the pen tip state detection signal Sd transmitted from the knock detector 140 regardless of the writing pressure data supplied from the pressure sensor 107. When it is determined that the state is the state, the LED 105 and the CMOS camera 106 are always driven. Therefore, when the pen point portion 103 of the electronic pen unit 104 is close to the dot pattern and the processor 108 can calculate the X and Y coordinates of the dot pattern from the image data supplied by the CMOS camera 106, the processor 108 Even before the pen tip portion 103 comes into contact with the DOL 30, entry information with a writing pressure of 0 (zero) is generated. Then, the processor 108 transmits the generated entry information to the computer apparatus 2 via the communication unit 111.

  When the computer device 2 receives the pen tip state detection signal Sd, the touch panel function restriction unit 244 of the processing unit 24 determines the input function of the touch panel 34 based on the pen tip state detection signal Sd transmitted from each electronic pen 1. Switch. Specifically, the touch panel function restriction unit 244 always changes the state of the pen tip portion 103 of each electronic pen 1 registered in the computer device 2 in advance based on the pen tip state detection signal Sd transmitted from each electronic pen 1. Monitor. Then, the touch panel function restriction unit 244 sets the touch panel function to OFF when the pen tip portions 103 of all the electronic pens 1 registered in the computer apparatus 2 are in the protruding state, and otherwise, will be described later. Process touch panel input in restricted mode. This will be specifically described with reference to FIGS. 15 (a) and 15 (b).

  FIGS. 15A and 15B illustrate the state of the electronic pen unit 104 of each electronic pen 1 when the electronic pen 1 with the pen ID “001” to “003” is registered in the computer apparatus 2. FIG. In FIG. 15A, all pen tip portions 103 of the electronic pen 1 with the pen ID “001”, the electronic pen 1 with the pen ID “002”, and the electronic pen 1 with the pen ID “003” are in the protruding state. It has become. In this case, the touch panel function restriction unit 244 determines that all users of the electronic pen 1 perform electronic pen input, and turns off the touch panel function to suppress unintended touch panel input.

  On the other hand, in FIG. 15B, the electronic pen unit 104 of the electronic pen 1 whose pen ID is “002” is in the stored state. In this case, the touch panel function restriction unit 244 determines that the user of the electronic pen 1 whose pen ID is “002” may perform touch panel input, and sets the input function of the touch panel 34 to a restriction mode described later.

  Next, the touch panel input process in the restriction mode will be specifically described. The touch panel function restriction unit 244 of the processing unit 24 is configured so that the pen point position (“electronic pen input position”) of the electronic pen unit 104 indicated by the coordinate information of the entry information while the computer apparatus 2 receives the entry information from the electronic pen 1. The input function of the touch panel 34 within a predetermined range 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 touch panel 34 is turned off based on the changed electronic pen input position. Hereinafter, a range in which the input function of the touch panel 34 is turned off based on the electronic pen input position is also referred to as a “restricted range Wr”.

  The specific processing of the touch panel function restriction unit 244 when the input function of the touch panel 34 is in the restriction mode will be further described with reference to FIG. FIG. 16 is an example of a display screen of the display device 3 in the third embodiment.

  In FIG. 16, the user touches the pen tip 103 of the electronic pen unit 104 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 having a radius R centered on the electronic pen input position as the limit range Wr, turns off the input function of the touch panel 34 in the limit range Wr, and sets the area outside the limit range Wr. The input function of the touch panel 34 is turned on. The radius R described above is set to, for example, 10 cm to 15 cm. Specifically, when an input is performed by the electronic pen unit 104 on the DOL 30, the side portion of the hand that holds the electronic pen 1 from the electronic pen input position. A maximum distance to a position at which there is a possibility of contact on the DOL 30 is obtained in advance by experiments or the like, and the radius R is determined as the maximum distance.

  Further, 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 touch panel 34 in the range. Therefore, while the stroke is drawn by the electronic pen unit 104, 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, in the input system according to the third embodiment, a processing flow for switching the input function of the touch panel 34 by the computer device 2 and a processing flow based on electronic pen input in the restriction mode will be described.

(Touch panel input function switching)
FIG. 17 is a flowchart showing a processing flow for switching the input function of the touch panel 34. The processing flow shown in FIG. 17 is repeatedly executed every time the computer apparatus 2 receives the pen tip state detection signal Sd from the electronic pen 1 or at a predetermined cycle.

  First, the touch panel function restriction unit 244 of the processing unit 24 projects the pen tip portions 103 of all the electronic pen units 104 of the registered electronic pen 1 based on the pen tip state detection signal Sd transmitted from each electronic pen 1. It is determined whether it is in a state (step S301). When the pen tip portions 103 of all the electronic pen portions 104 of the registered electronic pen 1 are in the protruding state (step S301; Yes), the touch panel function restriction unit 244 is configured to register the electronic pen 1 registered in the computer device 2. It is determined that all the users are willing to perform electronic pen input, and the touch panel function is set to OFF (step S302). Accordingly, the touch panel function restriction unit 244 suppresses unintended touch panel input.

  On the other hand, when the pen tip portion 103 of the electronic pen unit 104 of any one of the electronic pens 1 is registered in the electronic pen 1 registered in the computer device 2 (step S301; No), the touch panel function restriction unit 244 is Then, the touch panel function is set to the restriction mode (step S302). Accordingly, the touch panel function restriction unit 244 accepts a touch panel input of a user who does not perform an electronic pen input, and even when a side portion of a hand holding the electronic pen 1 is in contact with the DOL 30 during the electronic pen input. , Suppress processing as touch panel input.

(Processing in restricted mode)
FIG. 18 is a flowchart illustrating a processing flow based on electronic pen input in the restriction mode. The processing flow shown in FIG. 18 is repeatedly executed every time the computer apparatus 2 receives the entry information of writing pressure 0 by the electronic pen 1. Note that the processing flow shown in FIG. 18 is executed in parallel for each pen ID of the electronic pen 1 when the entry information is generated by a plurality of electronic pens 1 at the same time.

  When the user brings the electronic pen 1 close to the DOL 30 to a position where the dot pattern can be read, the electronic pen 1 associates the coordinate attribute information including the coordinate information obtained by imaging the dot pattern with the pen ID. The writing information of writing pressure 0 is transmitted to the computer device 2. In the computer apparatus 2, when the receiving unit 22 receives the entry information of the writing pressure 0 transmitted from the electronic pen 1, the processing unit 24 starts counting and sets the variable t whose initial value is 0 for a predetermined time. Only 1 is added for each width (step S401). Then, the processing unit 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 unit 25 (step S402). ). Then, the processing means 24 determines the electronic pen input position based on the converted coordinate information, and restricts the input function of the touch panel 34 within a predetermined range from the electronic pen input position (step S403). Specifically, the processing unit 24 turns off the input function of the touch panel 34 in the circular region having the radius R from the electronic pen input position.

  Next, the processing means 24 determines whether or not entry information whose writing pressure (p) is greater than 0 has been received (step S404). Thereby, the processing unit 24 determines whether the electronic pen input is performed in a state where the electronic pen 1 is in contact with the DOL 30 or whether the electronic pen 1 is close to the DOL 30 without being in contact therewith. If entry information with a writing pressure greater than 0 is not received (step S404; No), the processing unit 24 determines whether the variable t is greater than a predetermined value T (step S405), and the variable t is predetermined. If the value is equal to or smaller than the value T (step S405; No), the processing unit 24 returns to the process of step S404 and continuously monitors whether or not entry information having a writing pressure greater than 0 is received. Then, when the variable t becomes larger than the predetermined value T (step S405; Yes), the processing unit 24 uses the touch panel 34 based on the electronic pen input position of the electronic pen 1 to be processed in the processing flow. The restriction on the input function is released (step S412).

  On the other hand, if it is determined that entry information having a writing pressure greater than 0 has been received (step S404; Yes), the processing unit 24 determines that the electronic pen input has been performed while the electronic pen 1 is in contact with the DOL 30, and stores the information. The entry information is stored in the means 25 for each pen ID (step S406). 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 S407). Then, the processing unit 24 determines the electronic pen input position based on the converted coordinate information, and turns off the input function of the touch panel 34 in the circular area with the radius R from the electronic pen input position (step S408). Then, the processing unit 24 performs an electronic pen input process (step S409). 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. Are updated and stored in the storage means 25.

  Next, the processing means 24 determines whether or not entry information with a writing pressure greater than 0 is received (step S410), and determines that entry information with a writing pressure greater than 0 is received (step S410). ; Yes), the process proceeds to step S406, and the process is performed based on the entry information. On the other hand, when it is determined that entry information with a writing pressure greater than 0 has not been received (step S410; No), the processing unit 24 determines that the electronic pen 1 has moved away from the DOL 30, and then entered the writing pressure 0. It is determined whether information has been received (step S411). If it is determined that the entry information of writing pressure 0 is received (step S411; Yes), the processing unit 24 determines that the electronic pen 1 is in a proximity state where the dot pattern can be read with respect to the DOL 30. Returning to the process of step S410, it is determined again whether or not the pen of the electronic pen 1 is to be lowered.

  On the other hand, when it is determined that the entry information of writing pressure 0 is not received (step S411; No), the processing unit 24 moves away to a position where the electronic pen 1 cannot read the dot pattern with respect to the DOL 30, and the electronic pen by the user It is determined that the input is completed, and the restriction on the input function of the touch panel 34 based on the electronic pen input position of the electronic pen 1 that is the processing target in the processing flow is released (step S412).

[Concrete example]
Next, a specific example of the processing of the flowchart in the restriction mode shown in FIG. 18 will be described in more detail with reference to FIG. FIG. 19 is a diagram illustrating the positional relationship between the electronic pen 1 and the DOL 30 and the contents of entry information transmitted to the computer apparatus 2 in the case of each positional relationship. In the entry information shown in FIG. 19, (Xa, Ya) to (Xd, Yd) indicate coordinate values in the DOL coordinate system, “PD” indicates pen-down, and “PU” indicates pen-up. Shall.

  First, in FIG. 19A, the user brings the pen tip portion 103 of the electronic pen portion 104 of the electronic pen 1 close to the DOL 30. Thereby, the electronic pen 1 reads the dot pattern, generates entry information including the coordinate value of the DOL coordinate system and the information of the writing pressure 0, and transmits the entry information to the computer apparatus 2. The computer apparatus 2 receives the entry information of the writing pressure 0, increases the variable t and starts counting (see step S401), and turns off the input function of the touch panel 34 in the circular area having the radius R from the electronic pen input position. (See step S403). Then, the computer device 2 monitors whether or not the variable t becomes larger than the predetermined value T while receiving the entry information of the writing pressure 0 (see step S404 and step S405).

  Next, in FIG. 19B, the user pens down the pen tip portion 103 of the electronic pen portion 104 onto the DOL 30. In this case, the electronic pen 1 generates entry information including pen down information and writing pressure information greater than 0, and transmits the entry information to the computer apparatus 2. Since the computer apparatus 2 has received the entry information whose writing pressure is greater than 0 (see step S404), the computer device 2 performs electronic pen input processing based on the entry information while turning off the input function of the touch panel 34 in the limited range Wr. (Refer to step S406 thru | or step S409). Thereafter, the electronic pen 1 includes an entry including the coordinate value of the DOL30 coordinate system and writing pressure information greater than 0, while the user continues the entry with the pen point portion 103 of the electronic pen unit 104 pen-down. Information is generated and transmitted to the computer apparatus 2. In this case, since the computer apparatus 2 has received entry information whose writing pressure is greater than 0 (see step S410), the computer apparatus 2 continues to perform electronic pen input processing and the like (see steps S406 to S409).

  Next, in FIG. 19C, the user pens up the pen tip portion 103 of the electronic pen portion 104 and brings it close to the DOL 30. In this case, the electronic pen 1 generates entry information including pen-up information and writing pressure 0 information, and transmits the entry information to the computer device 2. In this case, the computer apparatus 2 monitors whether or not entry information of writing pressure 0 is received (see step S411).

  In FIG. 19D, the user pens down the pen tip portion 103 of the electronic pen unit 104 onto the DOL 30 again from the state of FIG. 19C. In this case, the computer apparatus 2 again receives entry information whose writing pressure is greater than 0 from the electronic pen 1 (see step S410), and performs electronic pen input processing based on the entry information (see steps S406 to S409).

  On the other hand, in FIG. 19 (e), the user further moves the pen tip portion 103 of the electronic pen unit 104 away from the DOL 30 from the state of FIG. 19 (c). In this case, since the electronic pen 1 cannot read the dot pattern, it does not generate entry information. Therefore, in this case, since the computer apparatus 2 no longer receives the entry information of the writing pressure 0 (see step S411), the restriction on the touch panel function is released (see step S412).

[Operational effects of the input system of the third embodiment]
According to the input system of the third embodiment, the computer apparatus 2 is configured such that all the electronic pen units 104 of the registered electronic pen 1 are in a protruding state based on the pen tip state detection signal Sd transmitted from each electronic pen 1. If there is, set the touch panel function to OFF. Thereby, when it is estimated that all the users of the electronic pen 1 are willing to perform electronic pen input, the computer apparatus 2 can turn off the touch panel function and suppress unintended touch panel input.

  Further, when any one of the registered electronic pens 1 is in the storage state, the computer apparatus 2 performs touch panel input processing in the restriction mode. The LED 105 and the CMOS camera 106 are always set to ON while the power of the electronic pen 1 itself is on. When the computer device 2 receives the entry information in the restriction mode, the computer device 2 is in the predetermined range Wr from the electronic pen input position. The input function of the touch panel 34 is limited. Thus, when the user performs electronic pen input, if the electronic pen 1 can read the dot pattern, the side of the hand that holds the electronic pen 1 before the pen tip of the electronic pen 1 contacts the DOL 30. Even before touching the DOL 30, the input function of the touch panel 34 in the predetermined range Wr from the electronic pen input position can be turned off. Therefore, the input system according to the third embodiment can prevent erroneous detection of touch panel input accompanying electronic pen input.

  Further, in the restriction mode, the computer device 2 turns off the input function of the touch panel 34 only within a predetermined range from the electronic pen input position, so that the side portion of the hand holding the electronic pen 1 contacts the DOL 30. In addition, it is possible to effectively process touch panel input by another user while preventing erroneous input caused by the above. Therefore, the third embodiment is also suitably applied to the case where the display device 3 has a large screen and there is a possibility that a plurality of persons perform touch panel input and electronic pen input.

  Further, the computer device 2 starts counting with the variable t after receiving the entry information of the writing pressure 0, and after that, even if the entry information with the writing pressure greater than 0 is not received, the variable t is greater than the predetermined value T. Until it becomes larger, the restriction on the input function of the touch panel 34 is not released. Thereby, it can suppress that the setting and cancellation | release of a restriction | limiting of the input function of the touch panel 34 generate | occur | produce frequently.

[Modification of Third Embodiment]
Next, a modification of the third embodiment will be described. In 3rd Embodiment, in addition to the modification 1 and the modification 2 of 1st Embodiment, the modification 3 and the modification 4 of 2nd Embodiment, the following modifications 5-7 are arbitrarily combined and applicable. .

(Modification 5)
In the description of FIG. 16, the processing unit 24 determines 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 to this. 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.

(Modification 6)
In the processing flow of FIG. 17, the touch panel function restriction unit 244 restricts the touch panel function when the electronic pen unit 104 of at least one electronic pen 1 among the electronic pens 1 registered in the computer apparatus 2 is stored. Mode. Instead, the touch panel function restriction unit 244 restricts the touch panel function in the restriction mode when the touch panel pen part 114 of at least one of the electronic pens 1 registered in the computer apparatus 2 is in the protruding state. In other cases, the touch panel function may be turned off.

  In this case, the knock detection unit 140 of the electronic pen 1 is added to or in place of the pen point unit 103 of the electronic pen unit 104. It is detected whether it is in the state. For example, when the electronic pen 1 has the configuration shown in FIG. 12 described in Modification 3 of the second embodiment, the knock detection unit 140 includes the touch panel pen unit in addition to the pen point unit 103 of the electronic pen unit 104. It is possible to detect whether the pen tip 113 of the 114 is in a protruding state or a retracted state. And when the knock detection part 140 detects the state transition of the pen point part 113 of the pen part 114 for touchscreens based on knock operation, it shows whether the said pen point part 113 is a protrusion state or the accommodation state. The pen tip state detection signal Sd is transmitted to the computer apparatus 2. The computer device 2 constantly monitors the state of the pen tip portion 113 of the touch panel pen portion 114 of each electronic pen 1 registered in advance in the computer device 2 based on the pen tip state detection signal Sd transmitted from each electronic pen 1. To do. Then, when the pen tip 113 of the touch panel pen unit 114 of the at least one electronic pen 1 is in the protruding state, the computer device 2 sets the touch panel function to the restriction mode, and the touch panel pen units 114 of all the electronic pens 1. When the pen tip 113 is in the retracted state, the touch panel function is turned off.

  Thus, in the modification 6, when it is estimated that any user may perform touch panel input with the electronic pen 1, the computer apparatus 2 sets the touch panel function to the restriction mode. To do. Thereby, the computer apparatus 2 receives the touch panel input of the user who does not perform the electronic pen input, and even when the side portion of the hand holding the electronic pen 1 is in contact with the DOL 30 during the electronic pen input, Processing as input can be suppressed. Further, when it is estimated that all users of the electronic pen 1 do not intend to perform touch panel input with the electronic pen 1, the computer device 2 can turn off the touch panel function and suppress unintended touch panel input.

(Modification 7)
In addition to the description of the third embodiment described above, when the computer apparatus 2 receives the entry information from the electronic pen 1 that is not registered in advance, the pen tip portion 103 protrudes from the electronic pen 1 in step S301 in FIG. You may add to the object which determines whether it is in a state.

  In addition to this, or instead of this, the computer apparatus 2 is limited to the electronic pen 1 that has transmitted the entry information received within a predetermined time width (for example, one hour or one and a half hours) from the present, as shown in FIG. In step S301, it may be determined whether or not the pen tip portion 103 is in the protruding state. Thereby, the computer apparatus 2 can determine suitably whether only the electronic pen 1 actually used is made into the object in step S301, and a touch panel function should be turned off or should be in a restriction | limiting mode.
