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, there is known a display device including an input device such as an electrostatic capacitance touch panel that enables input by touch operation.

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

  In such a display device, a user generally uses an active pen having a built-in battery to perform input, and for example, by pressing a button provided on the pen, the color of the writing and the line type are written. It is known that a plurality of pen IDs are distinguished by changing the attributes such as the above and changing the resonance frequency.

  On the other hand, in the display device of the electrostatic capacity method, since the change of the electrostatic capacity is detected, it is not always necessary to use the active pen as described above, and for example, a passive pen having a conductive tip embedded in the pen tip also draws. It is possible.

  However, in the former case, a battery is always required when using the active pen, and the shape of the pen itself is also limited. In addition, when a plurality of pens are used separately, there is a problem that not only the pens but also the main body of the display device that receives the pens need to be supported, which complicates the system.

  Also, in the latter case, since it is a passive pen, it is not possible to specify the user to use, and when changing the attributes of color and line type, it is necessary to change the setting each time each user fills in, There is a problem in that when the users of the above are writing at the same time, the change of the attribute is reflected to all the users.

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

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

JP, 2013-8317, A

  However, in the technique proposed in Patent Document 1, although it is described that an area that is touch-input by the user is detected, there is no description that the user is specified from the area.

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

In order to solve the above-mentioned problems, the input display device of the present invention is
An input display device comprising a display screen for displaying information and a sensor for detecting a user's input to the display screen,
An input area determination unit that determines whether the pen tip input area by the pen tip or the hand input area by the hand holding the pen is based on the input information detected by the sensor,
A user specifying unit that specifies a user based on a distance between the center points of the pen tip input area and the touch input area;

The center of each area is obtained and at least one of them is used to identify the user.

  The drawing information control unit (display switching unit, drawing unit) 8 includes a storage unit (not shown) inside, and the storage unit temporarily stores drawing information such as handwritten information and graph information. The menu information that is displayed by overlapping is stored in a separate layer.

  Further, the drawing information control unit 8 changes the drawing attribute based on the menu processing or the drawing processing from the touch recognition processing unit 5 and the user information from the user specifying unit 6, and stores the content 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 the information on the display unit 11.

It is explanatory drawing which shows an example of the input area detected by the electrostatic capacitance sensor when pen input is performed in the state in which the user B is touching the display screen in the input display device.

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

Specifically, 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 two users A and B perform pen input in a touched state are as follows. As shown in FIGS. 4 and 5.
Note that FIGS. 4 and 5 show a case where the input area is binarized with the threshold value A and the other remaining areas with the threshold value B, respectively.

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
Becomes Accordingly, 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.

From this, the distance between the first input area and the second input area is obtained and set as a 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 of.
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 of.

At least one is registered, and when the input by the user is performed, the data of the characteristic amount is collated, and if it is within ±10%, for example, the user is specified as the registered user. As a result, the user setting information (drawing attribute information) can be automatically set.
Even when the user's feature amount is not registered, it is possible to distinguish each user when inputting by a plurality of users, so that different drawing attributes can be set for each user. ..

Next, a procedure of processing for identifying a user who performs pen input in the input display device 1 of the first embodiment will be described with reference to a flowchart.
FIG. 6 is a flowchart showing a processing flow of the user specifying unit that specifies a user who inputs a display screen of the input display device according to the first embodiment.

  As shown in FIG. 6, when the user inputs an object (drawing information) to the display screen 10 with the pen in the input display device 1, the area determined as the pen input is determined from the determination result by the input area shape determination unit 4. It is extracted as the first input area (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 touched area of the hand holding the pen of the user 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, the distance D between the area center of the first input area for pen input calculated in step S102 and the area center of the second input area calculated in step S105 is calculated.

Then, the process proceeds to step S106 to calculate the X/Y direction length (LX/LY) of the second input region, and in step S107, the shape of the second input region is calculated as the feature amount.
In the first embodiment, the ratio of 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, in the second input regions 102A and 102B, the threshold value A is binarized, and “1 The average value of the electrostatic capacitances at the points "" is obtained.

  Then, the distance between the center points 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 staticity of the second input area calculated in step S108. Whether or not the input user is a registered user is determined based on at least one result of the average value of the electric capacities (step S109).

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

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

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

  When it is determined in step S121 that the input user is a registered user, the process proceeds to step S122, the user setting information is loaded by the drawing information control unit 8 and the user setting information of the input user is set. The user setting information is 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, when it is determined in step S121 that the input user is not the registered user, the process proceeds to step S123, and a representative color that is not used is set.

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

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

  In this way, after the user ID (information) corresponding to the input user and the attribute information are stored (registered), the processing flow of the user ID (information) is ended.

  As the 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 the user ID (information).

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

According to the conversion tables shown in FIGS. 8 and 9, when the user ID is 0x00, the line width is 0x2.
At 0.75pt, black, if the user ID is 0x01, the linewidth is 0x7 and the linewidth is 2pt, and if the user ID is 0x02, the linewidth is 0x2 and the linewidth is 0.75pt, and the linewidth is 0.75pt. become.

Based on the results of the user identification unit 6 that identifies the touch recognition processing unit 5 that determines the position of the pen tip based on the input information detected by the capacitance sensor, and the results of the user identification unit 6 and the touch recognition processing unit 5. And a drawing information control unit 8 for setting a drawing attribute for specifying a user, in the case where a touch input is made by a plurality of users, an input is made by a passive pen without using an active pen. However, the user ID can be set for each user, and the line width and line color can be easily set as the drawing attribute according to the user.

Processing is performed, and the “separation degree” of the second input areas 102A and 102B is set as a “feature amount”.

  For example, the second input area 102A of the user A is divided into two areas, a first area 102A1 and a second area 102A2, as shown in FIG.

  As shown in FIG. 11, the second input area 102B of the user B is divided into three areas, that is, a first area 102B1, a second area 102B2, and a third area 102B3, so that the degree of separation is 3.

  In the third embodiment, before the user actually uses the input display device 300, a message and sample characters are displayed in an arbitrary area of the display screen 310 as shown in FIGS. 12(a) and 12(b). By displaying and prompting the user to trace the sample character, the touch information is collated.

  The input display device 300 according to the third embodiment has the same configuration as the input display device 1 according to the first embodiment, and further has a collation screen that displays a message and sample characters as a function of displaying a screen on the display screen 10. The input area shape determination unit 4 has a display function, a function of detecting a touched area input when the user traces a sample character, and a function of the user identification unit 6 when the user traces a sample character. It is provided with a function of collating the touched area input to the user information (feature amount) of the registered user.

The screen 310 is instructed to display an attribute information selection screen (not shown).

  Then, it is determined from the result of the touch recognition processing unit 5 whether or not an input is made by the user (step S304).

  When it is determined in step S304 that the input is performed by the user, the color information set this time is stored (registered) as the attribute information of the input user in association with the user ID (information) specified by the user specifying unit 6. Then (step S305), the process ends.

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

  In this way, after the user ID (information) corresponding to the input user and the attribute information are stored (registered), the processing flow of the user ID (information) is ended.

  With the above-described configuration, according to the third embodiment, as the configuration of the input display device 300, the collation screen that displays the messages 321a and 321b and the sample characters 322a and 322b as a function of performing screen display on the display screen 310. The input area shape determining unit 4 has a display function, a function of detecting a touched area input when the user traces a sample character, and a function of the user specifying unit 6 is that the user sample characters 322a and 322b. The attribute information is registered in advance by collating the hand gesture information before the user inputs by providing the function to collate the hand gesture area input when tracing the user information (feature amount) of the registered user. Therefore, only the registered users can be used at the time of actual use. That is, at the time of actual use, it is possible to easily set the drawing attribute corresponding to the user only by loading/setting the user setting information based on the user information from the user specifying unit 6.

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

  As described above, according to the first to third embodiments, when a single user inputs, it is possible not only to automatically set the user setting information (drawing attribute information), but 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.

  Further, according to the above-described embodiment, it is possible to set the drawing color information, the line type information, and the like as the drawing attribute information for the user who inputs the pen. Functions can be realized with a passive pen.

  According to the input display device described above, the input display device includes a display screen that displays information and a sensor that detects a user's input on the display screen, and is capable of 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 shape of the second input area by the hand holding the pen are determined. An input area shape determination unit for determining, and a shape of the first input area and the second input area, a capacitance (capacitance value), and the first input area based on the determination result by the input area shape determination unit. A user identification unit that identifies the user by obtaining the center of each of the second input regions, a touch recognition processing unit that determines the position of the pen tip based on the input information detected by the sensor, and the user identification Section and a drawing information control section for setting a drawing attribute for specifying the user based on the result of the touch recognition processing section, so that the active pen can be used when touch input is performed by a plurality of users. It is possible to provide an input display device in which drawing attributes can be easily set according to each user even when input is performed with the passive pen without using it.

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