Description

  The present invention relates to an input display device, and more particularly to an input display device and the like capable of handwriting input with a pen provided with an input device such as a touch panel.

  2. Description of the Related Art Conventionally, a display device including an input device capable of inputting by a touch operation such as a capacitive touch panel is known.

  Display devices with input devices are used as electronic whiteboards / IWBs (interactive whiteboards) in classrooms and offices.

  In such a display device, the user generally inputs data using an active pen with a built-in battery. For example, by pressing a button provided on the pen, the color or line type of the writing is used. There are known ones in which a plurality of pen IDs are distinguished by changing the attribute or changing the resonance frequency.

  On the other hand, in a display device using a capacitance method, it is not always necessary to use an active pen as described above in order to detect a change in capacitance. For example, drawing is also performed with a passive pen in which a conductive tip is embedded in a pen tip. It is possible.

  However, in the former case, when the active pen is used, a battery is always required, and the shape of the pen itself is limited. Further, when a plurality of pens are used separately, not only the pens but also the display device main body side that receives them needs to be handled, and there is a problem that the system becomes complicated.

  In the latter case, since it is a passive pen, the user to be used cannot be specified, and when changing the color or line type attribute, it is necessary to change the setting every time each user fills in. When the users are simultaneously writing, there is a problem that the change of the attribute is reflected to all users.

  Therefore, in order to solve the above problem, as a conventional technique, for example, in a touch sensor system used in a display device, a two-dimensional region including one or more partial regions and a remaining region other than the partial region A first processing means for executing a first process based on a partial area touch signal corresponding to a touch on the partial area, and a residual area touch signal corresponding to a touch on the residual area. There has been proposed one including a second processing means for executing a second type of processing different from the first processing (see Patent Document 1).

  According to this, it is possible to perform a process for separately treating a signal based on an unintended touch input input to the partial area and a signal based on the intended touch input input to the remaining area. There is no possibility of misrecognizing a signal based on an unintended touch input that is input to the signal as a signal based on an intended pen input that is input to the remaining area.

JP 2013-8317 A

  However, the technique proposed in Patent Document 1 describes that an area detected by a user's touch input is detected, but does not describe that a user is specified from the area.

  The present invention has been made in view of the above-described conventional problems, and when touch input is performed by a plurality of users on the display screen of the input display device, input is performed by a passive pen without using an active pen. Even if it is performed, it is an object to provide an input display device or the like that can easily set drawing attributes according to each user.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram showing an example of pen input by a user in the input display device according to the first embodiment of the present invention, which is an example of an embodiment of the invention.

  As shown in FIG. 1, the input display device 1 according to the first embodiment includes a display screen 10 that displays information and a touch panel (sensor) 2 that detects user input to the display screen 10, and uses a pen 100. The input display device 1 capable of performing the input operation is characterized by having the characteristic input display device configuration according to the present invention.

  In FIG. 1, the display screen 10 in the input display device 1 shows a state where the user has started pen input.

First, a characteristic configuration of the input display device 1 will be described with reference to a block diagram.
FIG. 2 is a block diagram illustrating the configuration of the input display device according to the first embodiment, and FIG. 3 is an explanatory diagram illustrating an example of an input region detected by a capacitance sensor included in the input display device.

  As shown in FIG. 2, the input display device 1 includes a display screen 10 including a touch panel 2 and a display unit 11, a sensor driving unit / capacitance value receiving unit 3, a display driving unit 9, and a control unit 12. .

  The touch panel 2 includes a capacitance sensor and has a function capable of detecting a plurality of inputs.

  The control unit 12 includes a CPU, a ROM, and a RAM (not shown), and constructs an input area shape determination unit 4, a touch recognition processing unit 5, a user identification unit 6, and a drawing information control unit 8.

  The capacitance sensor that constitutes the touch panel 2 is a sensor that can detect the shape of an object by detecting the capacitance between adjacent objects from a plurality of lines arranged in a matrix. is there. The capacitance sensor can detect the capacitance at each position of 4096 × 2160, for example.

  Here, as shown in FIG. 1, the coordinates are set with the upper left corner of the display screen 10 as (0, 0) and the lower right corner as (4095, 2159). Is detected.

  The sensor driving unit / capacitance value receiving unit 3 drives the touch panel (capacitance sensor) 2 and detects the capacitance based on the result. The sensor driving unit / capacitance value receiving unit 3 sends the detected capacitance value to the control unit 12.

  The input region shape determination unit 4 in the control unit 12 determines the shape based on the capacitance detected by the sensor driving unit / capacitance value receiving unit 3, and the size of the detected shape (input region). Thus, as shown in FIG. 3, it is determined whether the detected object is the first input area 101 by the pen tip or the second input area 102 by the hand holding the pen.

  For example, when the area of the detected input area is smaller than a predetermined value, it is determined as the first input area 101 by the pen tip, and when the area of the detected input area is larger than the predetermined value, the hand holding the pen The second input area 102 is determined.

  In the first embodiment, “hand-held” refers to a state in which the hand of a hand holding a pen touches the display screen 10 when performing pen input.

  Moreover, although the pen 100 uses the passive pen, if it has electroconductivity and has a pen function, it will not limit to this.

  In the first embodiment, as shown in FIG. 3, when the user performs pen input in the input display device 1, the second input area 102 due to the hand holding the pen is determined depending on the state of the user's pen input. The shape, electrostatic capacity, and the distance D (103) between the area centers (area centroids) C (101) and C (102) of the first input area 101 and the second input area 102 are characteristically specified. It becomes possible.

  The separation of the first input area 101 by the pen tip and the second input area 102 by the hand holding the pen is performed as a pen input signal (drawing signal) even if the hand touches the display screen 10 as described in Patent Document 1. This is possible by defining an input area with a handle that is not handled and only handling a signal that touches the remaining area other than the input area with the handle as a pen input signal.

  Then, the input area shape determination unit 4 sends the determination result to the touch recognition processing unit 5 and the user identification unit 6.

  The touch recognition processing unit 5 determines the position of the pen tip based on the determination result of the input region shape determination unit 4, performs menu processing if the pen tip position is the menu position, and performs drawing processing if the pen position is not the menu position. Do.

  Based on the determination result of the input region shape determination unit 4, the user specifying unit 6 determines the shape and capacitance of the first input region 101 and the second input region 102, and the first input region 101 and the second input region 102. The center of each region is obtained, and the user is specified using at least one of them.

  The drawing information control unit (display switching unit, drawing unit) 8 includes a storage unit (not shown) therein, and the storage unit temporarily stores drawing information such as handwritten information and graph information and drawing information. Menu information that overlaps and is displayed in a separate layer.

  Further, the drawing information control unit 8 changes the drawing attribute based on the menu process or drawing process from the touch recognition processing unit 5 and the user information from the user specifying unit 6 and stores the contents to be displayed on the display unit 11. The contents of the storage unit are controlled to be updated.

  The display drive unit 9 drives the display unit 11 based on the information stored in the storage unit provided in the drawing information control unit 8 and displays information on the display unit 11.

  The display unit 11 is for giving information to the user by displaying it on the display screen 10, and has a planar shape such as a liquid crystal display or an EL display, for example. A touch panel 2 composed of a capacitance sensor is provided on the upper surface of the display unit 11 so as to overlap.

Here, the input area in the display screen 10 of the input display device 1 of the first embodiment will be described.
FIG. 4 is an explanatory diagram illustrating an example of an input area detected by a capacitance sensor when a pen input is performed in a state where the user A touches the display screen in the input display device of the first embodiment, and FIG. It is explanatory drawing which shows an example of the input area | region detected by the electrostatic capacitance sensor when pen input is performed in the said input display apparatus in the state which touched the display screen by the user B.

  As shown in FIG. 3, the input areas detected by the touch panel 2 of the display screen 10 of the input display device 1 are a first input area 101 by a pen tip and a second input area 102 by a hand holding a pen. .

Specifically, when comparing the input areas in the pen input by the two users A and B, the shapes of the second input areas 102A and 102B when the pen input is performed with the two users A and B touching, As shown in FIGS.
4 and 5 show cases where the input area is binarized with the threshold value A and the other remaining areas as the threshold value B, respectively.

  In the case of the user A, as shown in FIG. 4, the first input area 101 </ b> A by the pen tip has three sensors (LX = 3) in the X direction from X14 to X16 and four sensors in the Y direction from Y1 to Y4. Minute (LY = 4). The second input area 102A by the hand holding the pen is equivalent to 7 sensors (LX = 7) in the X direction from X2 to X8 and 15 sensors (LY = 15) in the Y direction from Y7 to Y21. Yes.

  In the case of the user B, as shown in FIG. 5, the first input area 101B by the pen tip has three sensors (LX = 3) in the X direction from X12 to X14, and four sensors in the Y direction from Y1 to Y4. Minute (LY = 4). The second input area 102B by the hand holding the pen is for six sensors (LX = 6) in the X direction from X3 to X8, and for 15 sensors (LY = 15) in the Y direction from Y5 to Y19. Yes.

In the first embodiment, in order to represent the shape of the second input areas 102A and 102B by the hand holding the pen in the users A and B as the feature amount, for example, the ratio of the vertical and horizontal lengths of the second input area, that is, A method represented by LX / LY is used.
In this case, if LX / LY of user A is LX (A) / LY (A) and LX / LY of user B is LX (B) / LY (B),
User A: LX (A) / LY (A) ≈0.47
User B: LX (B) / LY (B) ≈0.40
It becomes. Thereby, the user A and the user B can be identified by using the ratio of the vertical and horizontal lengths of the second input area as the feature amount.

  Next, the capacitance (capacitance value) of the input area in the input display device 1 of the first embodiment will be described.

In the input display device 1 of the first embodiment, in the second input areas 102A and 102B shown in FIG. 4 and FIG. Is obtained and set as a feature value.
For example, in the first embodiment, in the case of the second input area 102A of the user A shown in FIG. 4, it is about 5060, and in the case of the second input area 102B of the user B shown in FIG. .

  Next, the distance between the area centers of the first input area by the pen tip and the second input area by the hand holding the pen in the first embodiment will be described.

When the positions of the capacitance sensors X1, Y1 of the touch panel 2 are (X, Y) = (1, 1), and the area centers of the first input area and the second input area of the users A and B are obtained,
In the case of the user A, as shown in FIG. 4, the area center C (101A) of the first input area 101A is (15, 2.5), and the area center C (102A) of the second input area 102A is (5, 5). 14).
In the case of the user B, as shown in FIG. 5, the area center C (101B) of the first input area 101B is (13, 2.5), and the area center C (102B) of the second input area 102B is (5. 5, 12).

Thus, the distance between the first input area and the second input area is obtained and set as the feature amount.
In the case of the user A, as shown in FIG. 4, the distance D (103A) between the area center C (101A) of the first input area 101A and the area center C (102A) of the second input area 102A is 15.24 sensors. It becomes the distance.
In the case of the user B, as shown in FIG. 5, the distance D (103B) between the area center C (101B) of the first input area 101B and the area center C (102B) of the second input area 102B is 12.10 sensors. It becomes the distance.

As described above, among the feature quantities of the shape of the second input area when the user performs a pen input, the capacitance of the second input area, and the distance between the first input area and the center of the second input area At least one is registered, and when there is an input by the user, this feature amount data is collated, and if it is within a range of ± 10%, for example, the user is specified as a registered user Thus, the user setting information (drawing attribute information) can be automatically set.
Moreover, even when there is no registration of the user's feature value, since it is possible to distinguish each user when inputting by a plurality of users, it becomes possible to set different drawing attributes for each. .

Next, the procedure of the process which specifies the user who performs pen input in the input display apparatus 1 of 1st Embodiment is demonstrated along a flowchart.
FIG. 6 is a flowchart illustrating a processing flow of a user specifying unit that specifies a user to be input to the display screen of the input display device of the first embodiment.

  As shown in FIG. 6, in the input display device 1, when an object (drawing information) is pen-input by the user to the display screen 10, an area determined as pen input is determined based on a determination result by the input area shape determination unit 4. The first input area is extracted (step S101), and the area center of the first input area is calculated (step S102).

  In parallel with this, the second input area determined as the hand-held area of the hand holding the user's pen is extracted from the determination result by the input area shape determination unit 4 (step S104), and the area center of the second input area is extracted. Is calculated (step S105).

  In step S103, a distance D between the area center of the first input area where the pen input calculated in step S102 is performed and the area center of the second input area calculated in step S105 is calculated.

In step S106, the length (LX / LY) of the second input area in the X / Y direction is calculated. In step S107, the shape of the second input area is calculated as a feature amount.
In the first embodiment, the ratio between the lengths of LX and LY is calculated as the feature amount.

  Further, following step S104, the process proceeds to step S108 in parallel with step S105. For example, as shown in FIGS. 4 and 5, the second input areas 102A and 102B are binarized with the threshold A, and “1 ”Is determined.

  Then, the distance between the center of the first input area and the second input area calculated in step S103, the shape of the second input area calculated in step S107, and the static of the second input area calculated in step S108. It is determined whether or not the input user is a registered user based on the average value of the electric capacity and the result of at least one of them (step S109).

  If it is determined in step S109 that the input user is a registered user, the process proceeds to step S110, and a user ID (information) is output.

  On the other hand, if it is determined in step S109 that the input user is not a registered user, the process proceeds to step S111, and a new user ID (information) is output.

  In this manner, in the input display device 1, when the user inputs with the passive pen, the shape of the second input area due to the hand holding the user's pen, the capacitance, the first input area by the pen tip and the second The user can be specified from at least one piece of information of the distance between the center of each input area.

  If it is determined in step S121 that the input user is a registered user, the process proceeds to step S122, in which user setting information is loaded by the drawing information control unit 8, and user setting information of the input user is set. The user setting information includes drawing attribute information such as drawing color information and line type information.

  Then, after setting the user setting information of the input user, the processing flow of the user ID (information) is ended.

  On the other hand, if it is determined in step S121 that the input user is not a registered user, the process advances to step S123 to set a representative color that is not used.

  Then, the color information set this time is stored (registered) as attribute information of the input user in association with the user ID (information) specified by the user specifying unit 6 (step S124).

  Thus, if the same user inputs again after pen-up, the next time, the user is treated as a registered user, and drawing information is generated with the set attribute information.

  In this way, after storing (registering) the user ID (information) and attribute information corresponding to the input user, the processing flow of the user ID (information) is terminated.

  As user attribute information, for example, as shown in FIG. 8, line type information such as drawing color information and line width is stored in association with a user ID (information).

  In the first embodiment, as shown in FIG. 9, as shown in FIG. 9, a conversion table having line widths of 0.25 pt to 2 pt is prepared corresponding to the line widths of 0x0 to 0x7. The configuration refers to line width information. As for color information, 8 bits each of R, G, and B are stored, and thereby the drawing color of the user is determined.

  According to the conversion tables shown in FIGS. 8 and 9, when the user ID is 0x00, the line width 0x2 is 0.75 pt, black, and when the user ID is 0x01, the line width 0x7 is the line width 2 pt, blue, user When the ID is 0x02, the line width is 0x2, the line width is 0.75 pt, and the red color is drawn.

  Since it comprised as mentioned above, according to 1st Embodiment, the input display apparatus 1 is equipped with the function which can detect a some input in the touch panel 2 comprised by a capacitance sensor, and a capacitance sensor An input area shape determination unit 4 that determines the shape of the first input area 101 by the pen tip and the second input area 102 by the hand holding the pen based on the input information (capacity change) detected by 4, the user obtains the shapes, capacitances (capacitance values) of the first input region 101 and the second input region 102, and the center of each of the first input region 101 and the second input region 102 based on the determination result of 4. A user identifying unit 6 that identifies the touch, a touch recognition processing unit 5 that determines the position of the pen tip based on input information detected by the capacitance sensor, and a user identifying unit 6 and a touch By providing a drawing information control unit 8 that sets a drawing attribute that identifies a user based on the result of the recognition processing unit 5, when touch input is performed by a plurality of users, an active pen is not used. Even when input is performed with a passive pen, a user ID can be set for each user, and the line width and line color can be easily set as drawing attributes according to the user.

(Step S305), and the process ends.

  If it is determined in step S304 that there is no user input, the determination is repeated until there is a user input.

  In this way, after storing (registering) the user ID (information) and attribute information corresponding to the input user, the processing flow of the user ID (information) is terminated.

  Since it comprised as mentioned above, according to 3rd Embodiment, the collation screen which displays the message 321a, 321b and the sample character 322a, 322b as a function to perform a screen display on the display screen 310 as a structure of the input display apparatus 300 It has a display function, and as a function of the input area shape determination unit 4, it has a function of detecting a hand area that is input when the user traces a sample character. As a function of the user specifying unit 6, the user can use the sample characters 322 a and 322 b. Attribute information is registered in advance by checking the handle information before the user inputs it by providing a function that matches the handle area input when tracing Therefore, at the time of actual use, only registered users can be used. That is, at the time of actual use, the drawing attribute corresponding to the user can be easily set only by loading / setting the user setting information based on the user information from the user specifying unit 6.

  In the third embodiment, since attribute information can be set in advance for a plurality of users, each user can set each color without setting an unused color as in the first embodiment. Can use different attributes.

  As described above, according to the first to third embodiments, not only can user setting information (drawing attribute information) be automatically set when a single user inputs, but also a plurality of user setting information (drawing attribute information) can be set. Even when a human user inputs with a passive pen, if there is no user setting information, different drawing attributes can be set for each.

  In addition, according to the above-described embodiment, drawing color information, line type information, and the like can be set as drawing attribute information for a user who performs pen input. The function can be realized with a passive pen.

  Further, according to the above-described input display device, the input display device includes a display screen for displaying information and a sensor for detecting a user input to the display screen, and is capable of an input operation using a pen, The sensor has a function capable of detecting a plurality of inputs, and based on the input information (capacity change) detected by the sensor, the shape of the first input area by the pen tip and the second input area by the hand holding the pen is used. Based on the determination result by the input region shape determination unit and the input region shape determination unit to determine, the shape, capacitance (capacitance value) of the first input region and the second input region, and the first input region and Touch identification for determining the position of the pen tip based on input information detected by the sensor and a user identification unit that identifies a user by determining the center of each of the second input areas. When a touch input is performed by a plurality of users by including a processing unit, and a drawing information control unit that sets a drawing attribute for specifying a user based on the results of the user specifying unit and the touch recognition processing unit In addition, even when input is performed using a passive pen without using an active pen, it is possible to provide an input display device that can easily set drawing attributes according to each user.

  As described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the claims, that is, changes are made as appropriate without departing from the scope of the present invention.
