And a display device 103 having a display screen 104
And a control device 105 for controlling a screen displayed on the display screen 104 based on a signal input from the touch panel 101, and for controlling detection of a touch on the touch panel 101.

In the touch panel 101, the touch surface 102, which is a range in which a touch can be detected, is the display screen 10.
Display screen 1
A touched point on 04 (touch point) is detected. Further, the configuration for detecting the touch on the touch panel 101 includes a configuration for detecting the presence or absence of the touch and a configuration for detecting the time when the display screen 104 is touched.
A method for detecting touch points on the touch panel 101 will be described later.

In the present specification, touch means that the finger or pen touches the touch surface 102 once without touching the touch surface 102, and the finger or pen has already touched the touch surface 10.
It is distinguished from dragging moving on the touch surface 102 from the state of being touched by 2 and double-clicking making two touches within a predetermined time.

The control device 105 is a coordinate input device I / F which is an input / output interface with the touch panel 101.
112 (RS232C (Recommended Standard 232-
C), USB (Universal Serial Bus), etc. are connected to the touch panel 101), image output I / F 113,
An image RAM 114 in which R, G, B images displayed on the display screen 104 are expanded, a hard disk (HD) for storing data (font data, etc.) necessary for processing
HD for controlling data input / output of 117 and HD 117
I / F 115, CPU 106 that processes detection signals of the above-described configuration and an optical unit described later, ROM 107 that stores a program of processing performed by CPU 106, and the like.
RAM that temporarily stores data and programs required for processing
It is equipped with 109.

Further, the timer 111 of the control device 105 is
The time is constantly measured, and the measured time is periodically output to the CPU 106. The CPU 106 measures the time when the display screen 104 is touched by the time output by the timer 111.

FIG. 2 is a diagram for explaining the touch panel 101 in more detail. The touch panel 101 has a rectangular touch surface 102 with a horizontal length W and a vertical length H shown in the drawing. Side 2 which is one side of the touch surface 102 (overlaps the display screen 104) in the horizontal direction.
Optical coordinate detection devices 203a and 203b are provided at both ends of 04.
Is provided. A retroreflective member 201 is provided along the three sides of the touch surface 102 where the optical coordinate detection devices 203a and 203b are not provided.

The optical coordinate detecting devices 203a and 203b are provided with a light source (not shown) and a light receiving section composed of, for example, a plurality of light receiving elements. The light emitted from the light source spreads in a fan shape that requires the light source over the entire touch surface 102. And
The light is reflected by the retroreflective member 201 through the same optical axis as when it is incident, and is received by the light receiving unit.

When there is nothing such as a finger for blocking light on the touch surface 102, the light emitted from the light source is received by all the light receiving portions. However, the touch point t on the touch surface 102
When (X, Y) is touched, only the light receiving element corresponding to the optical axis of the reflected light passing through the touch point t in the light receiving section does not receive light. Therefore, from the position of the light receiving element that does not receive light, the angle θL formed by the optical axis of the light emitted from the optical coordinate detection device 203a and passing through the touch point t and the side 204.
I understand. Further, the angle θR formed by the optical axis of the light emitted from the optical coordinate detecting device 203b and passing through the touch point t and the side 204 can be known. Further, the coordinates (X, Y) of the touch point t can be found from the θL, θR, the length W, and the length H using the following formula. X = W × tan θR / (tan θL + tan θR) Y = H−W × tan θL × tan θR / (tan θL + ta
nθR)

The optical coordinate detecting device 203a and the optical coordinate detecting device 203b detect a light shield on the touch surface 102 about every 20 ms, and the coordinate input device I / O every 20 ms.
Input to the control device 105 via F112. The CPU 106 of the control device 105 converts the input coordinate data into signals such as touch, stop, drag, detach, and double click. Then, the CPU 106 controls each component of the control device 105 to control the image displayed on the display screen 104 according to the converted input signal and its coordinates.

The relationship between the above signals and the detection state of the optical coordinate detecting device is as follows. Touch The state where the light shield was not detected in the previous detection and the light shield was detected in this detection. Stopped The light block detected previously is in the same coordinates as the previous one even in this detection. Drag The light shield detected last time is in a different coordinate from the last time in this detection. Detached A state in which a light shield was detected in the previous detection, but no light shield was detected in this detection. Double-click A state in which two touches and two detachments are detected within a predetermined time within a predetermined range.

The display device with a touch panel according to the present embodiment described above operates as follows to select the display control mode. That is, the optical coordinate detection device 203
a, 203b and the control device 105 causes one point on the display screen 104 to have a predetermined time (stop touch time).
When the continuous touch (stop touch) is detected, the control device 105 activates the stop touch switching mode.

The display screen 104 has a plurality of display control modes (display control modes) such as drawing, image enlargement / reduction, and screen scrolling. When the stop touch switching mode is activated, the control device 105 sequentially displays a plurality of icons, each corresponding to the display control mode, in a predetermined range including one stop-touched point on the display screen 104. When the touch panel 101 detects the release (detach) of one touch point that is continuously touched, the display operation of the display is switched to the display control mode indicated by the icon displayed at this time.

The display device with a touch panel according to the present embodiment as described above can display the icon indicating the display control mode relatively close to the point where the operator is inputting the touch point. Therefore, the operator can change the display control mode by operating the icon without moving in front of the display screen 104 regardless of the standing position.

Further, the display device with a touch panel according to the present embodiment can register at least one of a display control mode indicated by a plurality of icons sequentially displayed or a display order of the plurality of icons.

FIGS. 3A and 3B are views for explaining a screen (stop touch mode registration screen) for registering the display control mode indicated by the icons sequentially displayed by the stop touch. The illustrated stop touch mode registration screen may be displayed on the display screen 104. If a general-purpose personal computer is used as the control device 105, it may be displayed on the screen of the personal computer.

The method of registering the display control mode displayed by the stop touch will be specifically described below using the stop touch mode registration screens shown in FIGS. 3 (a) and 3 (b). In the stop touch mode registration screen, as shown in (a), a display control mode selection field 301 for selecting a display control mode from a pull-down menu, a selection mode display field 302 for displaying all display control modes selectable as a stop touch mode, Stop touch mode column 30 for selecting the display control mode used as the stop touch mode in the display control mode displayed in the display control mode selection column 301
3. Add key 305 for displaying the display control mode in the stop touch mode column 303, delete key 306, up key 307 for setting the display order of the display control mode, down key 308, until it is determined to be a stop touch. And a stop touch time setting field 304 for setting a time for switching the icon display when it is determined that the touch is stopped.

The stop touch time setting field 304 is displayed on the key 30
By moving 9 in the direction of arrow a, the stop touch time and the time until the icon is switched are increased (the switching of the icons is slow), and by moving in the direction of arrow b, the stop touch time and the icons are switched. Set a shorter time (quickly switch icons) before being pressed. According to the inventor of the present invention, the time set by the stop touch time setting field 304 is preferably about 100 ms.

In this embodiment, as the display control modes selectable from the display control mode selection field 301, character drawing, graphic drawing, ruled line drawing, stamp drawing, enlarged display, reduced display, same-size display, scroll, Eleven items of eraser, color setting, and thickness setting are listed. The general operation performed by each display control mode is as follows.

Character Drawing A character is drawn by drawing a dragged trajectory as a line having a preset thickness and color. Drawing a circle by dragging,
Draw figures such as rectangles and lines. Ruled line drawing A horizontal line is drawn by dragging in the horizontal direction. Also, a vertical line is drawn by a drag operation in the vertical direction. Stamp drawing Draw specific image data at the touch point. Magnified display Enlarges and displays the specified area of the displayed image. Reduced display Reduces and displays the specified area of the displayed image. Same-size display Enlarges or reduces the displayed image to the original magnification. Scroll Drag to move the screen and display the part of the image that cannot be displayed because it was enlarged. Eraser Erases touched parts of drawn characters, figures, ruled lines, stamps, etc. Color setting Specify the color of drawn characters, figures, and ruled lines. Thickness setting Specify the thickness of drawn characters, figures, and ruled lines.

When registering the stop touch mode, the operator, as shown in FIG.
Select the display control mode from the 01 pull-down menu. By this operation, the content set on the screen is registered as the display control mode (stop touch mode of the character drawing mode) that can be switched by the stop touch switching mode in the selected display control mode (character drawing). .

Next, the operator selects the selection mode display field 3
Select one of the display control modes displayed in 02,
By clicking the add key 305, the stop touch mode at the time of character drawing is added. The added display control mode is displayed in the stop touch mode column 303. Further, among the display control modes once displayed in the stop touch mode column 303, those for which registration of the stop touch mode is desired to be canceled can be deleted from the stop touch mode column 303 by clicking the delete key 306.

The display control modes displayed in the stop touch mode column 303 can be changed in display order by clicking the up key 307 or the down key 308 after selection. In the present embodiment, the order of the display control modes displayed in the stop touch mode column 303 is directly used as the display order in the stop touch switching mode. Therefore, by operating the up key 307 and the down key 308, it is possible to set the display order of the display control mode at the time of stop touch.

The display order of the display control mode will be illustrated below. Note that the display order described below also changes depending on the relationship with the upper display control setting. The current mode (display control mode set using the toolbar just before the start of stop touch switching mode) draws characters. Character drawing → Eraser → Scroll → Character drawing Current mode Eraser Eraser → Eraser → Character drawing → Scroll → Eraser Current mode is scroll Scroll → Character drawing → Eraser → Scroll

In such a display device with a touch panel according to the present embodiment, the operator can set the display control mode that can be set in the stop touch switching mode and the switching order of the display control modes. For this reason,
The stop touch switching mode can be set according to the preference of each operator to enhance the operability of the display device with a touch panel.

Further, the display device with a touch panel according to the present embodiment has a setting for preventing a display not intended by the operator due to an erroneous recognition of an operation. Hereinafter, regarding this setting, FIG.
This will be specifically described with reference to (f).

As shown in FIG. 4A, in the display device with a touch panel according to the present embodiment, for example, when the display control of the display screen is character drawing, a stop touch is performed to move the pen on the display screen. The icon 401 is displayed. Then, when the stop touch is continued, the displayed pen icon 401 is sequentially switched to the eraser icon 402 and the scroll icon 403. Although the icons 401, 402, and 403 are shown at different positions in the figure, in reality, the icons 401, 40
2. The icon 403 is overwritten in the same place.

Further, as shown in FIG. 4A, in the display device with a touch panel according to the present embodiment, the icons that are sequentially displayed have different shapes such as a pen and an eraser defined for each display control mode. Have For example, when the operator wants to switch the display control mode to scroll, as shown in FIG. 4B, the operator detaches at the timing when the icon 403 is displayed.

At this time, the operator can easily understand the timing of switching to the desired display control mode while looking at the icons that are sequentially displayed, and it is less likely that the timing of detachment will be incorrect. Therefore, it is possible to prevent the operator from switching the display control mode of the display device with a touch panel to an unintended one, and to smoothly proceed with the presentation.

Further, as shown in FIG. 4C, in the display device with a touch panel according to the present embodiment, when a double click is detected by the touch panel 101,
The display operation of the display screen 104 is switched to the display control mode (current mode) set using the toolbar or the like immediately before entering the stop touch switching mode.

With the configuration described above, the display device with a touch panel according to the present embodiment can return the display control mode to the original state by a simple double-click operation. Therefore, even if the display control mode is unintentionally switched by the stop touch, it is possible to easily return to the original mode, and prevent an erroneous operation of the stop touch from hindering the smooth flow of the presentation. it can.

Further, in the present embodiment, as described above, the touch is defined as being touched once from the state where the touch surface 102 is not touched by the pen or the like, and is distinguished from the drag. Therefore, as shown in FIG. 4D, the display device with a touch panel has a pen icon 40.
When 1 stops in the process of drawing a line by a drag operation, even if the stop time is longer than the stop touch time, it is not judged as a stop touch and the stop touch switching mode is not activated. Such a display device with a touch panel according to the present embodiment can prevent unintentional activation of the stop touch switching mode when the operator stops the pen while drawing a character.

Further, in the display device with a touch panel according to the present embodiment, when the touch panel 101 detects a drag operation on the display screen 104 during activation of the stop touch switching mode, the dragged finger or pen releases the drag. The touch on the display screen 104 is disabled until it is detected (detached).

That is, in the display device with a touch panel according to the present embodiment, as shown in FIG. 4E, for example, the touch panel 101 detects a drag indicated by an arrow d during activation of the stop touch switching mode. In this case, the control device 105 performs processing to invalidate the input touch until the dragging finger or pen detaches (releases) from the display screen 104 (idle processing).
To do.

By the above idle processing, the display device with a touch panel according to the present embodiment does not switch the display control mode even if the operator stops the pen or finger during drawing. Therefore, it is possible to prevent the smooth progress of the presentation from being hindered by switching the display control mode without the operator's intention.

Further, in the display device with a touch panel according to the present embodiment, as shown in FIG. 4 (f), the shape of the pen is changed to the display control mode for character drawing by the stop touch switching mode, for example. The holding cursor 404 is displayed. While the stop touch switching mode is activated, the operator can intuitively understand the selected display control mode by reflecting the display control mode not only on the icon but also on the shape of the cursor. Unnecessary operations due to are reduced.

Further, in the display device with a touch panel according to the present embodiment, when the current mode is the drawing mode for drawing a line drawing, 1 on the display screen 104 is displayed.
When it is detected that the point is continuously touched for the stop time or longer, the stop touch switching mode is activated. Also,
When the stop touch switching mode is activated, the line drawing drawn at one point touched continuously for the stop touch time or longer is deleted.

That is, in the present embodiment in which the stop touch switching mode is activated by the stop touch, if the current mode is to draw a line drawing like the character drawing mode, the line drawing is drawn at the point where the stop touch is made. Will be. The line drawing drawn at the touch point is not drawn by the operator with the intention of drawing, and is deleted after the stop touch switching mode is activated. The present embodiment further simplifies the operation of the display device with a touch panel by automatically deleting the line drawing drawn at the touch point at the same time as the start of the stop touch switching mode (at the same time as the detection of the detachment). You can

FIGS. 5 and 6 are flowcharts for explaining the display control method performed by the display device with a touch panel according to the present embodiment described above. After the display device with a touch panel is activated, first,
The cursor in the currently set display control mode is displayed (step S501). Next, it is determined whether or not coordinates have been input (step S502), and when it is not determined that the coordinates have been input (step S502: No),
Wait until coordinates are entered.

When the display device with a touch panel determines that the coordinates have been input in step S502 (step S502: Yes), it determines whether the input coordinates are touch coordinates input by touch (step S503). ). As a result of this determination, if it is determined that the coordinates are touch coordinates (step S503: Ye
s), control (touch drawing control) assigned to a touch point such as changing the button display is executed (step S504).

Subsequently, the control device 105 starts the time counting by the timer 111 in order to time the stop touch time of the stop touch (step S505). Then, it is determined whether or not the input of coordinates is detected by the next detection by the touch panel 101 (step S501).

When it is determined in step S503 that the input coordinates are not the touch coordinates input by touch (step S503: No), the control device 10
Step 5 determines whether or not the input coordinates correspond to a stop (step S506). As a result, when it is determined that the stop is performed (step S506: Yes), it is determined whether or not the stop is in the stop touch (step S507), and subsequently, it is determined whether or not the stop touch time has elapsed (step S508). ).

In step S507, the stop touch is not in progress (step S507: No), or step S508.
When it is determined that the stop touch time has not elapsed (step S508: No), the control device 105 determines whether or not the input of coordinates is detected by the next detection by the touch panel 101 (step S501).

In step S507, the stop touch is in progress (step S507: Yes), or in step S507.
When it is determined in 508 that the stop touch time has elapsed (step S508: Yes), the control device 105 sets a predetermined range (relatively close) including the stop touch point according to the display of the stop touch mode registered in advance. An icon indicating the display control mode is displayed (step S509).
Furthermore, in order to measure the time for switching the displayed icon to another icon indicating another display control, the timer 111 starts counting (step S510).

If it is determined in step S506 that the input coordinates are not in the stopped state (step S506: No), it is determined whether or not the coordinates indicate dragging (step S511). Then, when it is determined that the dragging is performed (step S511: Yes), it is determined whether the dragging is performed during the stop touch (step S512). When it is determined that the drag is performed during the stop touch (step S512: Yes),
Idle processing is executed to invalidate the touch operation until the drag is detached (step S51).
3). Then, returning to step S501, it is determined whether or not the input of coordinates is detected in the next detection.

If it is determined in step S512 that the drag has not been performed during the stop touch (step S512: No), it is determined whether or not idle processing is in progress (step S514). If the result of determination is that idle processing is in progress (step S514: Yes),
Returning to step S501, it is determined whether or not the input of coordinates is detected in the next detection.

For example, the control assigned to double-clicking (double-click drawing control) such as displaying a dialog box is executed (step S519). When it is determined in step S516 that the input is not a double click (step S516: No), the touch panel 101 determines whether the input indicates detach (step S520). If it is not detached (step S520: No), the process returns to step S501 to determine whether or not the input of coordinates is detected in the next detection.

If it is determined in step S520 that the input indicates detachment (step S52).
0: Yes), the control device 105 determines whether or not the stop touch is in progress (step S521). As a result, when the stop touch is being performed (step S521: Yes),
The display screen 104 is switched to the display control mode indicated by the icon displayed at the time of detaching (step S522). Then, the cursor corresponding to the switched display control mode is displayed (step S523) and the status is cleared (step S524).

When it is determined in step S521 that the stop touch is not in progress (step S521: N
o), it is determined whether or not the idle process is being performed (step S525). As a result, when it is determined that the idle process is being performed (step S525: Yes), the status is cleared and the process returns to step S501. If it is determined that the idle processing is not in progress (step S525: N
o), the control assigned to the detachment (detach drawing control) is executed, such as confirming the range selected by the drag operation (step S527).
