Abstract

PROBLEM TO BE SOLVED: To enable, with a simple constitution, pen input on an arbitrary area on a panel surface allowing a hand to touch the panel and to enable both pen input and finger input. SOLUTION: On the top surface of a liquid crystal display part 10, a depression coordinate detection layer 30 is arranged which has detection unit areas which have a width smaller than that of a finger and are arrayed in xy directions and detects a coordinate position pressed with a pen, the hand holding the pen, or a finger. An ineffective area setting part 41 sets the area of a coordinate position pressed with the hand holding the pen as an ineffective area whose positions are determined relative to the pen coordinate values. A discrimination part 40 decides the pen coordinate values from the depression coordinate values calculated by a depression coordinate calculation part 38, calculates the ineffective area for the foregoing pen coordinate values, and decides that the coordinate values in the ineffective area other than the pen coordinate values indicate the coordinate position inputted by the depression by the hand holding the pen and coordinate values outside the calculated ineffective area indicate the coordinate position pressed with the finger for operation input.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coordinate input device for detecting a coordinate position designated by a pen (pen-shaped writing instrument) or a finger, which is used in portable information equipment and the like.

[0002]

2. Description of the Related Art Conventionally, as a coordinate input device as described above, a resistive film system, an electromagnetic induction system, an electrostatic coupling system, an ultrasonic system, an infrared system and the like have been considered.

In the resistive film system, two resistive films are overlapped with a slight gap, and the two resistive films are brought into contact and energized at a point depressed by a pen or a finger. Is detected to detect the coordinate position of a point pressed by a pen or a finger.

The electromagnetic induction system uses a dedicated electronic pen having an LC circuit consisting of an inductance and a capacitor embedded at the tip, forms a line-shaped or loop-shaped electrode pattern on the panel side, and moves the pen close to the electrode pattern. The coordinate position of the point pointed by the pen is detected by utilizing the fact that the induced voltage is obtained when the point is touched.

In the electrostatic coupling method, electrodes are provided at four corners of a panel, and an alternating voltage is applied to a conductive thin film coated on the panel surface. A current proportional to the distance to the finger is caused to flow, and by measuring the ratio of the current, the coordinate position of the point where the pen or the finger touches is detected.

In the ultrasonic system, ultrasonic waves transmitted from an ultrasonic transmitter provided at a corner of a panel are scanned as surface acoustic waves throughout the input area of the panel, and the ultrasonic waves are provided on a pen. The coordinate position of the point designated by the pen is detected from the time required until the sound wave is received by the sound wave receiver and the propagation speed of the ultrasonic wave.

[0007] In the infrared method, an infrared beam is spread over a panel surface like a mesh, and when the infrared beam is blocked by a pen or a finger, it is detected where the infrared beam is blocked. Or to detect the coordinate position of a point designated by a finger.

[0008]

However, in the conventional resistive film system, the electrostatic coupling system, the ultrasonic system and the infrared system described above, when a pen is held in contact with the panel surface when inputting a pen, it is not possible to use such a system. Is also determined to be an input, so that the hand holding the pen cannot be brought into contact with the panel surface, resulting in poor operability when inputting with the pen.

However, Japanese Patent Application Laid-Open No. 9-44304 discloses that
In the resistive film method, the density of the spacer inserted between the two resistive films is increased in the area where the hand holding the pen touches the panel surface when inputting the pen, and the hand holding the pen touches the area. It is also disclosed that the hand holding the pen can be brought into contact with the panel surface by preventing the two resistive films from contacting and energizing.

However, in this method, pen input becomes difficult in an area where the spacer density is high, and the area where the spacer density is high is fixed. Therefore, the same device is used for both right-handed and left-handed persons. There is a drawback that you can not.

On the other hand, in the electromagnetic induction method, the hand holding the pen can be brought into contact with the panel surface, and although the pen input is easy, only the special pen can be used and the input by the finger cannot be performed. In addition, all operations such as window operations and scroll operations, such as those performed with a mouse on a personal computer, must be performed with the pen, which increases the load on the hand holding the pen, which also results in poor operability. is there.

Further, in both of the conventional methods, even if both pen input and finger input are possible, they cannot be distinguished from each other. In such a case, it is not possible to perform automatic division between pen input and finger input, such as operation such as window operation or scroll operation, while at the same time handwriting input of characters and figures with a pen, The problem is that separate operations or inputs cannot be performed at the same time with a pen and a finger, such as performing a window operation or scroll operation with a finger, and the operation input speed cannot be increased in a portable information device or the like. There is.

Japanese Patent Application Laid-Open No. 6-67788 discloses that, in a resistive film system, one of two resistive films is constituted by a plurality of belt-like resistive films divided in one direction, and a plurality of belt-like resistive films are formed. When the film is in contact with and energized with the other resistive film, for example, when a pen is input with the pen in the right hand, the left resistive film is depressed by the pen and the right resistive film is It is shown that the hand holding the pen can be brought into contact with the panel surface by making it invalid when pressed by the hand holding the pen. However, this method also cannot perform pen input and finger input simultaneously.

In Japanese Patent Application Laid-Open No. 9-44293, in the electrostatic coupling method, an invalid input area is set in accordance with the setting of a handwriting input frame, and a hand holding a pen is brought into contact with the invalid input area. However, this method also has a problem that it is impossible to make a hand in the handwriting input frame, and it is impossible to simultaneously perform the pen input and the finger input.

Therefore, according to the present invention, with a simple configuration, it is possible to input a pen by touching an arbitrary area on the panel surface with a hand, thereby performing pen input with good operability and without fatigue of the hand. In this case, pen input and finger input can be performed simultaneously.

[0016]

According to the present invention, as a coordinate input device, a detection unit area that is stacked on a display unit and that is smaller than the width of a finger is arranged in one direction along a display surface of the display unit.
And a pressed coordinate detection layer arranged in a direction intersecting with this, and a pressed coordinate value obtained by the pressed coordinate detection layer, a coordinate position pressed by a pen, a coordinate position pressed by a hand holding the pen, And identification determining means for identifying and determining coordinate positions pressed by a finger for operation or input.

[0017]

In the coordinate input device according to the present invention, the coordinate position pressed by the pen, the coordinate position pressed by the hand holding the pen, and the operation input are provided by the pressed coordinate detection layer. The coordinate position pressed by the finger, that is, the coordinate position pressed by the pen, hand or finger touching the panel surface is all detected as the pressed coordinate value.

In the identification determining means, the coordinate position pressed by the pen, the coordinate position pressed by the hand holding the pen, and the finger for operation input are determined from the pressed coordinate value obtained by the pressed coordinate detection layer. The coordinate position depressed is identified and determined.

More specifically, the detection unit area of the pressed coordinate detection layer is smaller than the width of the finger, and at a certain moment, what is pressed by the pen is an isolated detection unit area. A plurality of adjacent detection unit areas are pressed by a finger for operation input, and a plurality of adjacent detection unit areas are pressed by a hand holding a pen. When the pressed coordinate value obtained by the layer is an isolated coordinate value for one detection unit area, the pressed coordinate value is determined to be the coordinate position pressed by the pen, and is determined by the pressed coordinate detection layer. When the pressed coordinate value is composed of coordinate values of a plurality of adjacent detection unit areas, the pressed coordinate value is determined by a coordinate position pressed by a hand holding a pen or by a finger for operation input. It is determined that please coordinate position.

Further, a right-handed person holds the pen with his right hand,
When making a pen input by touching the right hand with the panel surface, the side of the little finger side of the right hand contacts the panel surface within a certain area located at the lower right with respect to the pen tip, a left-handed person holds the pen with his left hand, When inputting a pen with the left hand in contact with the panel surface, the side of the left finger on the little finger side contacts the panel surface in a certain area located at the lower left with respect to the tip of the pen. For each pen coordinate value that is the coordinate value determined as the coordinate position, the area of the coordinate position pressed by the hand holding the pen is calculated as an invalid area whose position is determined relative to the pen coordinate value. The pressed coordinate value obtained by the pressed coordinate detection layer is
When the coordinate value is within the calculated invalid area, the pressed coordinate value is determined as the coordinate position pressed by the hand holding the pen, and the pressed coordinate value obtained by the pressed coordinate detection layer is calculated as the calculated invalid value. If the coordinate value is outside the area, the pressed coordinate value is determined to be the coordinate position pressed by the finger for the operation input.

Alternatively, as described above, the area of contact between the hand and the panel surface when a pen holding hand is in contact with the panel surface and a pen input is performed is determined when the finger is brought into contact with the panel surface for operation input. Since the pressed coordinate value obtained by the pressed coordinate detection layer is considerably larger than the contact area between the finger and the panel surface, if the pressed coordinate value obtained by the pressed coordinate detection layer is more than a predetermined number of adjacent detection unit areas, the pressed coordinate value is Is determined as the coordinate position pressed by the hand holding the pen, and when the pressed coordinate value obtained by the pressed coordinate detection layer includes the coordinate values of the predetermined number of adjacent detection unit areas or less, the pressed coordinate value is Is determined as the coordinate position pressed by the finger for the operation input.

As described above, when a hand holding the pen is brought into contact with the panel surface and a pen input is made, the coordinate position pressed by the hand holding the pen is identified, and the coordinate value is excluded from the processing target. The pen input can be performed by touching the hand to an arbitrary area on the panel surface, and the pen input can be performed with good operability and without tired hands.

Further, since the coordinate position pressed by the pen and the coordinate position pressed by the finger for operation input are distinguished from each other, pen input and finger input can be performed simultaneously. It is possible to perform automatic classification of pen input and finger input, such as handwriting input such as characters and figures when using pen input, and window operation or scrolling operation when using finger input. The pen and finger can simultaneously perform separate operations or input, such as performing handwriting input of characters and figures with a pen while simultaneously performing window operations and scrolling operations with a finger on the other hand. The operation input speed can be increased in information devices and the like.

Moreover, since only the pressed coordinate detection layer needs to be laminated on the display unit, the configuration of the coordinate input device is simplified.

A protective insulating layer is provided thereover.

The pressed coordinate detection layer 30 contacts the coordinate position pressed by the pen 1, the coordinate position pressed by the hand holding the pen 1, and the coordinate position pressed by the finger for operation input, ie, the panel surface. In order to detect all coordinate positions depressed by the pen 1, hand and finger, transparent line-shaped conductors 31a, 31b... 31j are arranged in the y direction as shown in FIG. And transparent linear conductors 32a, 32b ... 3
2j are arranged in the x direction. The pen 1 may be any pen as long as it has a pointed tip.

As shown in FIG. 3, conductors 31a to 31j
Is overlapped with one of the conductors 32a to 32j as a unit area for detecting the pressed coordinates. This unit area 3 is smaller than the width of the finger, and at a certain moment,
The unit pressed by the pen 1 is an isolated unit area, but the unit pressed by a finger for operation input is a plurality of adjacent unit areas as shown by a finger pressed area 4. To do. Specifically, the conductors 31a-3
The widths of 1j and 32a to 32j are 0.3 to 3 respectively.

Conductors 31a-31j and 32a-32
j are formed on the insulating substrate by printing, vapor deposition, or the like, and are overlapped with a slight gap so that when the pressed coordinate detection layer 30 is not pressed by any of the pen 1, hand or finger, the two are insulated from each other. Match.

FIG. 4 shows the overall configuration of the coordinate input device of this embodiment, in which the switch circuits 33 are sequentially switched.
A predetermined voltage Vo from the power supply 35 is sequentially applied to the conductors 31a, 31b,.
During the period in which the predetermined voltage Vo is being applied to the conductor 31a, the switch circuit 34 is sequentially switched to sequentially connect the conductors 32a, 32b... 32j arranged in the x direction to the detection resistor 36, and so on. A predetermined voltage V on the conductor 31b
During the period during which the voltage o is applied, the switch circuit 34 is sequentially switched to sequentially connect the conductors 32a, 32b,.
The conductors 31a to 31j scan the intersections of the conductors 31a to 31j in the x and y directions.
A predetermined voltage Vo is applied to j, and the conductors 32a to 32j are connected to the detection resistor 36.

Thus, for example, when the intersection of the conductors 31a, 31b and the conductors 32a, 32b and the intersection of the conductor 31i and the conductor 32i are pressed by the pen 1, the hand or the finger, , Conductor 31
The conductors 31a, 31b and the conductors 32a, 32b come into contact with each other and conduct electricity at the intersections of the conductors 31a, 32b with the conductors 31i, 32i at the intersections of the conductors 31i, 32i. Is in contact with
When a predetermined voltage Vo is applied to the conductor 31a and the conductor 32a is connected to the detection resistor 36, the predetermined voltage Vo is applied to the conductor 31a, and the conductor 32b is connected to the detection resistor 36. , The predetermined voltage Vo is applied to the conductor 31b, and the conductor 32b
a is connected to the detection resistor 36, the conductor 3
The timing at which a predetermined voltage Vo is applied to 1b and the conductor 32b is connected to the detection resistor 36,
At the timing when the predetermined voltage Vo is applied to the detection resistor 36 and the conductor 32i is connected to the detection resistor 36, a predetermined current flows through the detection resistor 36 and reaches a predetermined voltage Vo between both ends of the detection resistor 36. Is obtained.

Therefore, by detecting the timing when the voltage Vr obtained between both ends of the detection resistor 36 reaches the predetermined voltage Vo, the coordinate position pressed by the pen 1, hand or finger is detected. be able to.

Contrary to the method described above, the conductors 31a, 31
.. 31j are sequentially connected to a detection resistor.
During the period in which the conductor 31a is connected to the detection resistor, a predetermined voltage is sequentially applied to the conductors 32a, 32b... 32j, and in the period in which the conductor 31b is similarly connected to the detection resistor, 32j are sequentially applied to the conductors 32a, 32b,.
The conductors 31a to 31j may be connected to a detection resistor and a predetermined voltage may be applied to the conductors 32a to 32j so that the intersection of the conductor 32a and the conductors 31a to 31j is scanned in the x and y directions. Good.

The voltage measuring section 37 compares the voltage Vr obtained between both ends of the detection resistor 36 with a threshold voltage slightly lower than the predetermined voltage Vo, and determines whether the voltage Vr exceeds the threshold voltage and reaches the predetermined voltage Vo. The pressed coordinate calculation unit 38 calculates the coordinate position pressed by the pen 1, the hand, or the finger from the timing when the voltage Vr reaches the predetermined voltage Vo.

Further, in this embodiment,
In the invalid area setting unit 41, the area of the coordinate position pressed by the hand holding the pen 1 is set as an invalid area in which the position relative to the coordinate position pressed by the pen 1 is determined.

That is, when a right-handed person holds the pen 1 with his right hand and touches the panel with the right hand to make a pen input, as shown in FIG. Coordinate value Pd = (Xa + Xd, Ya-Y) located at the lower right with respect to Pa = (Xa, Ya)
d) is the point at the upper left corner, and the coordinate value Pe = (Xa + Xd + X
w, Ya-Yd) is the point at the upper right corner, and the coordinate value Pf = (X
a + Xd, Ya-Yd-Yw) is defined as a point at the lower left corner, and a coordinate value Pg = (Xa + Xd + Xw, Ya-Yd-Yw) is defined as a point at the lower right corner. Contact.

A left-handed person holds the pen 1 with his left hand,
When pen input is performed by touching the left hand with the panel surface, coordinate values Pd ′ = (Xa−Xd, Y) located at the lower left with respect to pen coordinate values Pa = (Xa, Ya), as shown in FIG.
a−Yd) is defined as a point at the upper right corner, and the coordinate value Pe ′ = (Xa−
Xd-Xw, Ya-Yd) is the point at the upper left corner, and the coordinate value P
f ′ = (Xa−Xd, Ya−Yd−Yw) is set as the lower right corner point, and the coordinate value Pg ′ = (Xa−Xd−Xw, Ya−Yd)
In a region 2L having −Yw) as a point at the lower left corner, the side surface on the little finger side of the left hand contacts the panel surface.

Therefore, the invalid area setting section 41 sets the pen coordinates Pa = (Xa,
Distances Xd and Yd in the x and y directions with respect to Ya) and area 2
The widths Xw and Yw in the x and y directions of R and 2L are set.

In this case, when uniformly defining the size of the invalid area, the widths Xw and Yw are set to be large because the size of human hands varies. However, even in this case, the user of the device specifies whether the user is right-handed or left-handed as the initial setting of the device, and the invalid area setting unit 41 determines whether the pen input by the right hand or the left hand is performed according to the specification. Are represented by the distances Xd and Yd and the widths Xw and Yw.
It can be configured to be set together with.

As an initial setting of the apparatus, the user of the apparatus actually touches the pen 1 and the hand holding the pen 1 on the panel surface, and the identification determining section 4 described later of the apparatus.
0 is the coordinate position pressed by the pen 1 at that time,
And the coordinate position pressed by the hand holding the pen 1 is determined, and the area 2R or 2L is determined therefrom to calculate the distances Xd and Yd and the widths Xw and Yw. May be configured to be set to.

The discrimination determination section 40 determines the pen 1 based on the pressed coordinate value calculated by the pressed coordinate calculation section 38 and the result set by the invalid area setting section 41 by a determination processing routine 50 as shown in FIG. The coordinate position pressed by the user, the coordinate position pressed by the hand holding the pen 1, and the coordinate position pressed by the finger for operation input are identified and determined. The identification determining unit 40 includes a CPU,
It has a ROM in which a program such as the above-described determination processing routine 50 to be executed by the CPU is written, a RAM functioning as a work area of the CPU, and the like.

First, in step 51, an isolated coordinate value for one detection unit area is searched from the pressed coordinate value calculated by the pressed coordinate calculation unit 38, and then in step 5
In step 2, the retrieved coordinate value is determined as the coordinate position pressed by the pen 1.

Next, in step 53, the pen 1
The pen coordinate value Pa = (Xa, Ya) which is the coordinate value determined as the coordinate position pressed by the invalid area setting unit 41
From the distance Xd, Yd and the width Xw, Yw, the pen coordinate value Pa = (Xa, Y
As an invalid area for a), the coordinate value Pd = (Xa + Xd, Ya-Yd) as shown in FIG.
The coordinate value Pe = (Xa + Xd + Xw, Ya-Yd) is the point at the upper right corner, and the coordinate value Pf = (Xa + Xd, Ya-Yd-Y)
w) is the point at the lower left corner, coordinate value Pg = (Xa + Xd + Xw,
A region 2R having the lower right corner as a point at Ya-Yd-Yw) or a coordinate value Pd '= (Xa-Xd, Ya-Yd) at a point at the upper right corner, and a coordinate value Pe' = (Xa-Xd-Xw, Ya-Y
d) is the point at the upper left corner, coordinate value Pf ′ = (Xa−Xd, Ya)
−Yd−Yw) at the lower right corner, coordinate value Pg ′ = (Xa−
Xd-Xw, Ya-Yd-Yw) is calculated as a region 2L having a point at the lower left corner.

Next, at step 54, one of the pressed coordinate values other than the pen coordinate value Pa is selected.
In 5, it is determined whether the selected pressed coordinate value is within the area 2R or 2L calculated in step 53.

When the selected pressed coordinate value is Pb = (Xb, Y
b), (Xa + Xd) ≦ Xb ≦ (Xa + Xd + Xw) or (Xa−Xd−Xw) ≦ Xb ≦ (Xa−Xd), and (Ya−Yd−Yw) ≦ Yb ≦ (Ya−Yd) , The pressed coordinate value Pb = (Xb, Yb)
Within the region 2R or 2L.

If the selected pressed coordinate value is within the area 2R or 2L, the process proceeds from step 55 to step 56, where the selected pressed coordinate value is the coordinate position pressed by the hand holding the pen 1. After that, the process further proceeds to step 57, where the pen coordinate value P
It is determined whether or not there is a pressed coordinate value other than a, and if there is no other pressed coordinate value other than the pen coordinate value Pa, the determination process ends, but there is another pressed coordinate value other than the pen coordinate value Pa. For example, the process returns to step 54, and another one of the pressed coordinate values other than the pen coordinate value Pa is selected.

When it is determined in step 55 that the pressed coordinate value selected in step 54 is not within the area 2R or 2L, the process proceeds from step 56 to step 58, where the selected pressed coordinate value is pressed by the pen 1. It is determined that the coordinate position is neither the coordinate position that was pressed nor the coordinate position pressed by the hand holding the pen 1, nor the coordinate position that was pressed by the finger for the operation input. It is determined whether or not there is a pressed coordinate value other than the coordinate value Pa. If there is no other pressed coordinate value other than the pen coordinate value Pa, the determination process is terminated. If there is, step 5
Returning to step 4, another pressed coordinate value other than the pen coordinate value Pa is selected.

As described above, for all of the pressed coordinate values obtained at a certain moment, whether the coordinate position is pressed by the pen 1 or the coordinate position pressed by the hand holding the pen 1 Therefore, it is determined whether or not the coordinate position is pressed by a finger.

The discrimination determining section 40 determines the pressed coordinate value determined as the coordinate position pressed by the pen 1, that is, the pen coordinate value Pa, on the liquid crystal display section 10 at the position of the coordinate value Pa. Is displayed on the liquid crystal display unit 10 at the position of the coordinate value Pa by displaying a line, a point, or the like that constitutes a part of the character, and performing a handwriting pen input of a character or a figure. And input processing.

The discrimination determination unit 40 invalidates the coordinate value of the pressed coordinate determined as the coordinate position pressed by the hand holding the pen 1 and does not perform any special processing.

Further, the discrimination determining section 40 determines, for the pressed coordinate value determined as the coordinate position pressed by the finger for the operation input, the liquid crystal display section 1 at the position of the coordinate value.
An operation or input of an item displayed as an icon or the like is performed at 0.

As described above, the contact area between the hand and the panel surface when the hand holding the pen 1 is brought into contact with the panel surface to perform pen input is determined by the finger when the finger is brought into contact with the panel surface for operation input. It is considerably larger than the contact area between the panel and the panel surface.

Therefore, as in the embodiment shown in FIGS. 4 to 6 and described above, by setting and calculating the invalid area, the coordinate position pressed by the hand holding the pen 1 and the finger for the operation input are set. When the pressed coordinate value calculated by the pressed coordinate calculation unit 38 consists of coordinate values of adjacent detection unit areas exceeding a predetermined number instead of identifying the coordinate position pressed by the When the pressed coordinate value calculated by the pressed coordinate calculation unit 38 is determined to be the coordinate position of the adjacent detection unit area of a predetermined number or less, the pressed coordinate value is determined as: It may be determined that the coordinate position has been pressed by a finger for an operation input. In this case, it is possible to identify and determine that the input is a finger input even when a finger input is performed without a pen input.

As described above, according to the present invention, with a simple configuration, a pen can be input by touching an arbitrary area on the panel surface with a hand, thereby improving operability and avoiding tired hands. Input can be performed, and pen input and finger input can be performed simultaneously.
