Description

Method for determining touch position and touch panel device applying the method

The present invention relates to a touch panel, and more particularly, to a touch position determining method and a touch panel device to which the method is applied.

In general, a touch panel device detects the location of a user's hand or an object by touching a character or a specific location on a screen (screen) without using a separate key input device (for example, a keyboard). It is an interactive system that can receive input data directly from the screen for specific processing.

That is, the touch panel is a device that provides an interface between a screen screen such as a PDP, an LCD, or another type of flat panel display (FDP), which is an image information output device, and a user. Specific application examples of such a touch panel include an automatic cash advance and withdrawal device of a bank. Basically, the touch panel is composed of a signal generator and a control unit (for example, a computer). The signal generating device on the screen screen in which the user's finger or the indicator bar touches the screen reads its position in abscissa, that is, coordinates (x, y) and transmits it to the computer that is the controller. The computer provides an interface between the user and the image by matching that position with the image at that position on the screen.

The touch panel device is classified into a resistive method, a capacitive method, and an infrared method. The resistance method has a disadvantage in that the screen is not clean by attaching a thin film to the glass plate. The capacitive method has a disadvantage in that it does not recognize any medium other than the operator's hand.

On the other hand, the infrared method is to add a device called a touch panel (panel) to the screen portion of the general monitor to perform a function, the touch panel to the left / right / up / down invisible infrared flows to the screen portion By creating a large number of square grids, they have the ability to locate their location when they touch the grid with a fingertip or other object.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a touch panel device for determining a touch position according to an embodiment of the present invention.

Referring to FIG. 1, the touch panel device 100 according to the present exemplary embodiment may include a controller 110, a display unit 120, a touch panel 130, a coordinate calculator 140, a touch position determiner 150, and storage. The unit 160 is included.

The controller 110 may include internal functional elements of the touch panel apparatus 100 according to the present invention (eg, the display unit 120, the touch panel 130, the coordinate calculator 140, and the touch position determiner 150). And the storage unit 160, etc.).

In addition, the controller 110 divides the touch panel 130 into n (n is a natural number of two or more) sub regions, and controls the storage unit 160 to store information about the divided sub regions. For example, the n sub-regions may be partitions formed by orthogonally crossing n-1 horizontal strokes and n-1 vertical strokes of the touch panel 130. Each sub area is given an address based on a constant origin as a coordinate value, and the coordinate value for the position of each sub area is stored in the storage unit 160 and configured.

The display unit 120 controls data corresponding to a command input by the user through the input unit under the control of the controller 110 (for example, an application execution screen executed by the user, a command input through the input unit, a selection command, etc.). ) Is displayed. The display unit 120 may be, for example, a PDP, an LCD, or another type of flat panel display (FPD) or LCD.

The touch panel 130 is a means for receiving a control command, a selection command, or the like for controlling an operation of the touch panel device 100 from a user. For example, the touch panel 130 is positioned on an upper surface of the display unit 120 such as an PDP, LCD, or FPD, which is an image information output device, and serves to provide an interface between the touch panel device 100 and a user.

In addition, the touch panel 130 generates a touch signal at the touched point. In the present embodiment, the touch area refers to an area including one or more sensing means for generating a touch signal. Here, the sensing means is a means for detecting a touch and generating a touch signal by using a resistance wire, a resistive film, a capacitance, and / or an infrared method.

For example, the touch panel 130 includes a glass plate and a film film coated with ITO, and a constant voltage is applied to the glass plate and the film film. At this time, if a touch or the like by applying a force on the surface of the touch panel 130 with a hand or an indicator bar, the film of the surface is pressed in and touches the glass plate coated with ITO. At this time, a contact occurs to generate a potential difference in the sensing means of the point, and converts it into a touch signal to provide the coordinate calculation unit 140.

The coordinate calculator 140 extracts the position coordinates of the reference point of the touched touch region and the position coordinates of each center point of k subregions including the touch region (k is a natural number of n or less). In the present exemplary embodiment, the reference point means one point (coordinate) of the touch area in which the touch panel 130 is touched, and may be, for example, a center point (center coordinate) of the touch area. In addition, the center point means one point (coordinate) in the sub area in the touch panel 130, and may be, for example, a center point (center coordinate) of the sub area.

For example, when a touch is applied, each of the sensing means included in the sub area generates a touch signal. At this time, the position coordinates of the touched sensing means, the touched time, and the touched pressure may be recognized using the touch signal generated. For example, the position coordinates of the touched sensing means calculate a voltage through an electrode connected to the film film and the glass plate to calculate X and Y coordinate values of the contact point. At this time, the calculation of the X, Y coordinate value further includes the step of converting the extracted coordinate value by using the analog voltage difference to convert to a digital value.

In the present embodiment, the position coordinates of each center point of k subregions including the touch region (k is a natural number of n or less) recognizes a subregion that generates a touch signal, and is a center coordinate preset in the subregion. It may be calculated by extracting from the storage 160.

If there are a plurality of touched sub-regions, the touch position determiner 150 determines one or more sub-regions as the touch positions intended by the user. In the present exemplary embodiment, the touch position determiner 150 may determine a distance between a reference point of the touch area and a center point of each of the sub areas of the sub areas including the touch areas (eg, k is a natural number of n or less). The at least one subregion of the k subregions is determined as a touch position according to the calculated distance.

In this case, the touch position determiner 150 may extract a center point located at the shortest distance of the distance between the reference point of the touch area and the center point of each of the k sub-regions, and determine the sub-region including the extracted center point as the touch position. .

In addition, when the center point located at the shortest distance from the reference point is two or more, the touch position determiner 150 may determine only one sub-area as the touch position in consideration of touch time or touch pressure. For example, when the touch point determining unit 150 has two or more center points located at the shortest distance between the reference point of the touch area and the center point of each of the k sub-areas, the touch time of the sub-region including the center point is faster. The sub area may be determined as a touch position. In addition, the touch position determiner 150 may recognize a sub-region in which the touch pressure is greater among the sub-regions including the extracted center point as a touch point intended by the user and determine the touch position.

According to another aspect of the present invention, the number of the sensing means of each of the k sub-regions (k is a natural number of n or less) including the touch area is measured, and the sub-region having the largest number of the sensing means measured The touch position can be determined. At this time, the number of sensing means initially included in the n sub-regions is the same.

The storage unit 160 may be accessed from a ROM (Read Only Memory), EPIROM (EEPROM: Electrically Erasable and Programmable Read Only Memory), and terminal operation operation in which unique data of a terminal, an operation program, and the like are stored. It consists of a random access memory (RAM) that stores the data input through. In addition, the storage unit 160 includes k algorithms including an algorithm for operating the touch panel apparatus 100 according to an exemplary embodiment of the present invention, n sub-region information, position coordinates of one or more touch regions, and a touch region. (k is a natural number less than or equal to n).

FIG. 2 is a diagram illustrating a touch panel divided into a plurality of sub areas according to an embodiment of the present invention, and FIG. 3 illustrates a touch position when a circular touch area is applied according to an embodiment of the present invention. 4 is an exemplary diagram illustrating a determining principle, and FIG. 4 is an exemplary diagram illustrating a principle of determining a touch position when an elliptic touch region is applied according to an embodiment of the present invention.

In the present invention, the touch panel device 100 divides the touch panel 130 into n sub-regions. Referring to FIG. 2, the touch panel device 100 is divided into 12 sub-areas divided into four vertical strokes and three horizontal strokes by orthogonal to (0, 0), which is the center of the touch panel 130. . As illustrated in FIG. 2, each sub-region may be recognized as a coordinate value, that is, an (x, y) value with respect to the origin.

When a user applies a touch to the divided touch panel 130 using a finger or an indicator bar, the touched region may overlap two or more sub-regions. In this case, the present invention is for determining which section the sub-region desired by the actual user is.

Referring to FIG. 3, when the shape of the touched area is a circle shape, a sub area which is the shortest distance from the center of the circle is determined as the touch position. In other words, when the touch area includes both the A area and the B area, the present invention determines which of the two areas is selected as the touch position.

To this end, in the present embodiment, a formula for obtaining the center coordinates of a circle may be used. The formula to find the center coordinates of a circle is as follows.

[Equation 1]

(x-x1) ^ 2 + (y-y1) ^ 2 = c ^ 2

Where c is the radius of the circle and (x1, y1) is the center coordinate value of the circle. c corresponds to half of the difference between the minimum and maximum values of x (the diameter of the circle). Therefore, by using the above equation, it is possible to calculate the center coordinate values (x1, y1) of the circle. For example, the touch region including the sensing means for generating the touch signal may be recognized, and the center coordinate value of the circle may be calculated using the coordinate values of the sensing means at the edge of the touch region. In the present embodiment, it is assumed that the center coordinate value of the circle thus calculated is the coordinate value of the reference point.

In addition, it is assumed that the coordinate value of the center point of the area A and the coordinate value of the center point of the area B are set in advance. In addition, the distance between the center point of the area A and the center point of the area B from the reference point is expressed as an absolute value, and is assumed to be L1 and L2 values, respectively.

At this time, the calculation method for calculating the distances L1 and L2 uses the Pythagorean theorem that the square of the length of the hypotenuse of the right triangle is equal to the sum of the squares of the lengths of the other two sides. That is, suppose that each distance L1 between the reference point of the touch area and the center point of the area A is obtained in FIG. 3, the square of the distance difference between the reference point and the center point of the area A and the distance of the y axis between the reference point and the center point of the A area. The square of the difference is equal to the square of the distance between L1. The same applies to finding the respective distance L2 between the reference point of the touch area and the center point of the A area.

Thus, L1 ² = (6-5.3) ² + (2-(-0.3)) ² is calculated as L1 ≒ 2.404, and L2 ² = (6-5.3) ² + (-2-(-0.3)) ² by L2 ≒ Computed to 1.838. At this time, since the touch panel device 100 corresponds to a distance shorter than L1, the touch panel device 100 determines the region B including L2 as a desired touch position.

FIG. 4 illustrates a process of determining a touch position when a touch area is an ellipse, assuming that a finger is generally recognized as an ellipse rather than a circle. 4 is different from the equation for calculating the reference point of FIG. 3 and the touch area, and the rest are the same.

Referring to FIG. 4, a parabolic equation is used to obtain an elliptic center coordinate (reference point). The parabolic equation is

[Equation 2]

x1 ^ 2 / a ^ 2 + y2 ^ 2 / b ^ 2 = 1

a and b are the long and short radius of the ellipse, respectively, and the center coordinate values (x1, y1) of the circle can be calculated in the above equation, and this embodiment assumes that the coordinate value of the reference point. In addition, the distance between the center point of the C region, the center point of the region D and the center point of the region E from the reference point is expressed as an absolute value, and is assumed to be L3, L4, and L5, respectively.

Using the Pythagorean theorem as in FIG. 3, L3 ² = (6-7) ² + (6- (2.2)) ² , L1 ≒ 3.8, and L4 ² = (6-7) ² + (2- (2.2 L2 ² 1.019 by ² ) and L5 ² = (6-7) ² + (-2- (2.2)) ² by L2 ≒ 4.2.

At this time, L4 is smaller than L3 and L5 to be the shortest distance. Therefore, although the user selects the touch area to overlap the C, D, and E areas, the D area may be determined as the touch position because the user actually tries to recognize the D area having a short distance.

5 is a flowchart illustrating a method of determining a touch position in a touch panel device according to an embodiment of the present invention. Each step described below is performed by each internal component of the touch panel device 100, but will be collectively described as the touch panel device 100 for convenience of understanding and explanation.

In operation 510, the touch panel apparatus 100 divides the touch panel 130 into n sub-regions where n is a natural number of two or more. For example, the n sub-regions may be partitions formed by orthogonally crossing n-1 horizontal strokes and n-1 vertical strokes of the touch panel 130.

In operation 520, the touch panel apparatus 100 calculates position coordinates of each center point of k displays (k is a natural number of n or less) including a touch area. In this case, the position coordinate of each center point may be a preset value.

In operation 530, when a touch is applied to the touch panel 130, the touch panel apparatus 100 calculates position coordinates of a reference point of the touched region. In order to calculate the position coordinates, the touch panel apparatus 100 calculates the X and Y coordinate values of a point where contact occurs by, for example, calculating a voltage through an electrode connected to the film film and the glass plate. In this case, the calculation of the X and Y coordinate values may further include converting the extracted coordinate values into digital values using analog voltage differences.

In operation 540, the touch panel apparatus 100 calculates a distance between a reference point of the touch area and a center point of each of the k sub-areas. In this case, the distance is calculated by substituting the position coordinates into the Pythagorean theorem when the position coordinates of the reference point and the position coordinates of the center point are the values of the X axis and the Y axis.

In operation 550, the touch panel apparatus 100 determines at least one of the k sub-areas as a touch position according to the calculated distance. In detail, the touch panel apparatus 100 extracts a center point located at the shortest distance between the reference point of the touch area and the center point of each of the k sub-areas, and determines the sub-region including the extracted center point as the touch position. do.

According to another embodiment of the present invention, the touch panel device 100 may occur when the extracted center point is 2 or more, that is, when the center point corresponding to the shortest distance is 2 or more. In this case, the touch panel apparatus 100 selects a sub area based on a preset criterion.

As an example, when the extracted center point is 2 or more, the touch panel device 100 may determine a touch area as a touch area with a quick touch time among the sub areas including the extracted center point. This may be determined by selecting a section in which the touch signal is first generated among the two or more sub-regions. In addition, when the extracted center point is 2 or more, the touch panel device 100 may determine a sub area in which the touch pressure is greater among the sub areas including the extracted center point as the touch position. Any method for calculating the touch pressure may be within the scope of the present invention as long as it is known in the art. In addition, when the extracted center point is 2 or more, the touch panel device 100 may determine all of the sub-regions including the 2 or more center points as the touch position.

The method for editing subtitles in the touch panel apparatus 100 according to the present invention may be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer readable medium. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination. Program instructions recorded on the media may be those specially designed and constructed for the purposes of the present invention, or they may be of the kind well-known and available to those having skill in the computer software arts. Examples of computer-readable recording media include magnetic media, such as hard disks, floppy disks, and magnetic tape, optical media such as CD-ROMs, DVDs, and magnetic disks, such as floppy disks. Magneto-optical media, and hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like. The medium may be a transmission medium such as an optical or metal wire, a waveguide, or the like including a carrier wave for transmitting a signal specifying a program command, a data structure, or the like. Examples of program instructions include not only machine code generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like. The hardware device described above may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.
