Description

How to Control Character Behavior on Touch Input Devices

The present invention relates to a method of controlling the behavior of a character in a touch input device, and more particularly, to a method of controlling the behavior of a predetermined character according to a pressure touch on the touch input device.

Various types of input devices for operating computing systems, such as buttons, keys, joysticks, and touch screens, have been developed and used. Among them, the touch screen has attracted the most attention because it has various advantages such as ease of operation, miniaturization of a product, and simplification of a manufacturing process.

The touch screen may constitute a touch surface of a touch input device including a touch sensor panel. The touch sensor panel may be attached to the front of the touch screen to cover the touch screen. The user may operate the corresponding device by touching the touch screen with a finger or the like. The device detects the touch and the position by the user and performs an operation corresponding to the user's operation.

Most devices (eg, mobile terminals, PDAs, etc.) employing a touch screen determine a user's touch and position and perform a specific operation. In detail, when a user touches a region where an application is displayed, the corresponding device detects a location where a touch is made and executes, drives, or terminates the application. Each device may run an application based on touch time, frequency, or pattern. For example, an object displayed by long touch, double touch, multi touch, or the like may be operated in various ways.

However, since the above-described conventional touch control method performs a specific operation based on the touch position, the pattern, and the time, an operation that can be controlled is limited. At the present time, the functions of various devices are integrated, and the functions thereof are also becoming more diverse, and there is a need for a new touch method that can escape from the conventional touch control method.

However, while reproducing a conventional touch control method as it is, it is not easy to simultaneously implement a new touch method, and there is a problem that it is difficult to detect both simultaneously without time division.

An object of the present invention is to provide a method for controlling the behavior of a character used in various applications in response to a pressure touch input by a user to a touch input device.

In addition, the present invention provides a method for controlling the behavior of the character according to the amount of pressure input.

In addition, the present invention provides a method for controlling the behavior of the character according to the touch type according to the magnitude of the input pressure.

In addition, the present invention provides a method of controlling a character's behavior according to an input touch time.

However, the object of the present invention is not limited to the above objects, and may be variously expanded within a range without departing from the spirit and scope of the present invention.

Here, the touch type determination step, if the magnitude of the pressure of the object is less than the first reference pressure is determined as a simple touch, if the first reference pressure or more is determined as a pressure touch, the behavior control step, the touch type If the simple touch, the character may be controlled to perform the first action, and if the touch type is the pressure touch, the character may be controlled to perform a second action different from the first action.

Here, in the touch type determination step, if the magnitude of the pressure of the object is greater than or equal to the first reference pressure and less than the second reference pressure, it is determined as a weak pressure touch, and if it is greater than or equal to the second reference pressure, a strong pressure touch is determined. In the behavior control step, if the touch type is the weak pressure touch, the character performs the second action; if the touch type is the strong pressure touch, the character performs a third action different from the second action. Can be controlled.

Here, in the detecting step, the controller detects a touch time of the object input to the touch input unit, and in the behavior control step, the character performs the action when the touch time is within a preset reference time range. The controller may control to perform an action different from the action when the reference time range is exceeded.

Here, in the detecting step, the controller detects a touch position of the object input to the touch input unit, and in the behavior control step, the action performed by the character may be controlled according to the touch position. .

According to the present invention, by using a new touch method based on touch pressure, there is an advantage that can control the behavior of the character applicable to various applications.

The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively referred to as "graphics").

The touch input unit 100 functions as an input means. To this end, the touch input unit 100 includes a touch sensor module 110. Here, the function as the input means detects the touch information input to the touch input unit 100.

The touch information includes 2D touch information and 3D touch information. That is, it includes 2D touch information about whether a touch is input (touch or not) and at which position on the surface of the touch input unit 100 (touch position). Furthermore, the touch information may further include information about whether the touch is a 2D touch or a 3D touch having a pressure of a predetermined size or more. In this case, the 3D touch may refer to a touch having a pressure enough to cause warpage on the surface of the touch input unit 100.

The touch input unit 100 may be called a “touch and pressure sensitive touch screen”.

The term 'strength' of the touch on the surface of the touch input unit 100 refers to the force or pressure (force per unit area) of the contact (eg, finger contact) on the surface of the touch input unit 100. The intensity of the contact has various values, including at least four distinct values and more typically including hundreds (eg, at least 256) distinct values.

In addition, the touch sensor module 110 may be embedded in the display module 150. Specific embodiments of the touch input unit 100 will be described later with reference to the accompanying drawings.

Hereinafter, the structure of the touch input unit 100 will be described with reference to FIGS. 2 to 13.

As shown in FIG. 2, the

pressure electrodes

450 and 460 according to the first embodiment of the present invention may be formed on the substrate 300 as the spacer layer 420.

The

pressure electrodes

450 and 460 for detecting pressure may include a first electrode 450 and a second electrode 460. At this time, any one of the first electrode 450 and the second electrode 460 may be a driving electrode and the other may be a receiving electrode. The driving signal may be applied to the driving electrode and the sensing signal may be obtained through the receiving electrode. When a voltage is applied, mutual capacitance may be generated between the first electrode 450 and the second electrode 460.

The lower surface of the display module 150 may have a ground potential for noise shielding. When pressure is applied to the surface of the touch sensor module 110 of FIG. 1 through the object h, the touch sensor module 110 and the display module 150 may be bent. Accordingly, the distance d between the ground potential surface and the

pressure electrode patterns

450 and 460 may be reduced to (d ′). In this case, since the fringe capacitance is absorbed by the lower surface of the display module 150 as the distance d decreases, the mutual capacitance between the first electrode 450 and the second electrode 460 may decrease. have. Therefore, the magnitude of the touch pressure may be calculated by obtaining a reduction amount of mutual capacitance from the sensing signal obtained through the receiving electrode.

The display module 150 may be bent in response to a touch applying a pressure. The display module 150 may be bent to show the largest deformation in the position of the touch. According to an exemplary embodiment, the position showing the greatest deformation when the display module 150 is bent may not coincide with the touch position, but the display module 150 may be at least bent at the touch position. For example, when the touch position is close to the edge and the edge of the display module 150, the position where the display module 150 is bent the most may be different from the touch position, but the display module 150 is at least bent at the touch position. Can be represented.

The upper surface of the substrate 30 may also have a ground potential for noise shielding. Accordingly, the

pressure electrodes

450 and 460 may be formed on an insulating layer (not shown) in order to prevent the substrate 30 and the

pressure electrodes

450 and 460 from being short circuited. According to an exemplary embodiment, an insulating layer (not shown) on which the

pressure electrodes

450 and 460 are formed may be attached to the substrate 30. In addition, according to the exemplary embodiment, the

pressure electrodes

450 and 460 may include a mask having a through hole corresponding to the pressure electrode pattern on the substrate 30 or an insulating layer (not shown) on the substrate 30. It can be formed by spraying a conductive spray.

When the lower surface of the display module 150 has a ground potential, the

pressure electrodes

450 and 460 positioned on the substrate 30 and the display modules 150 are disposed on the

pressure electrodes

450 and 460 to prevent the display module 150 from being shorted. An insulating layer (not shown) may be disposed.

An insulating layer may be disposed above and below the

pressure electrodes

450 and 460 with the

pressure electrodes

450 and 460 interposed therebetween. The two insulating layers and the

pressure electrodes

450 and 460 may form one pressure sheet.

According to the type and / or implementation manner of the touch input unit 100 of FIG. 1, the substrate 30 or the display module 150 to which the

pressure electrodes

450 and 460 are attached may not exhibit ground potential or may exhibit weak ground potential. have. In this case, the touch input unit 100 illustrated in FIG. 1 may further include a ground electrode (not shown) between the substrate 30 or the display module 150 and an insulating layer (not shown). In some embodiments, the semiconductor device may further include another insulating layer (not shown) disposed between the ground electrode and the substrate 30 or the display module 150. In this case, the ground electrode (not shown) may prevent the size of the capacitance generated between the first electrode 450 and the second electrode 460, which are pressure electrodes, from becoming too large.

In order to hold the spacer layer 420, an adhesive tape 440 having a predetermined thickness may be formed along an edge of the upper portion of the substrate 30. The adhesive tape 440 may be a double-sided adhesive tape. The adhesive tape 440 may be made of a material having no elasticity. In the exemplary embodiment of the present invention, when the pressure is applied to the display module 150, the display module 150 may be bent, so that the size of the touch pressure may be detected even if the adhesive tape 440 does not have deformation of the shape according to the pressure. have.

Although not illustrated in a separate drawing, the

pressure electrodes

450 and 460 may be disposed on the lower surface of the display module 150. In this case, the substrate 30 may have a ground potential. Accordingly, as the touch surface of the touch sensor module 110 of FIG. 1 is touched, the distance d between the substrate 30 and the

pressure electrodes

450 and 460 is reduced, and as a result, the first electrode 450 and the first electrode are reduced. This may cause a change in mutual capacitance between the two electrodes 460. Through this, the magnitude of the touch pressure can be calculated. In addition, the magnetic capacitances of the

pressure electrodes

450 and 460 change according to the distance change between the

pressure electrodes

450 and 460 and the substrate 30 as the reference potential layer. The magnitude of the pressure can be calculated.

Although not illustrated in a separate drawing, any one of the first electrode 450 and the second electrode 460 may be formed on the substrate 30, and the other may be formed under the display module 150. . The distance between the first electrode 450 and the second electrode 460 decreases due to the force of the object h, and as the distance decreases, the distance between the first electrode 450 and the second electrode 460 decreases. Capacitance changes. The magnitude of the touch pressure may be calculated by obtaining a reduction amount of mutual capacitance from a sensing signal acquired through any one of the first electrode 450 and the second electrode 460.

The touch input unit 100 illustrated in FIG. 3 has a structure in which a pressure electrode P is disposed in the display module 150 illustrated in FIG. 1.

As shown in FIG. 3, the

OLED display modules

160, 161, and 162 include an organic material layer 160 between the first substrate layer 161 and the second substrate layer 162. The pressure electrode P for detecting the touch pressure may be formed on the upper surface of the second substrate layer 162. The pressure electrode P may use a light shield (LS) for blocking light inflow, a gate electrode, a source electrode, a drain electrode, a pixel electrode, or the like. In some cases, a separate metal may be deposited to be used for pressure detection. It may be. Furthermore, the separate structure which consists of metal materials is provided and can also be used for pressure detection.

Although not illustrated in the drawings, the pressure electrode P may be formed on the top or bottom surface of the first substrate layer 161 or on the bottom surface of the second substrate layer 160.

The reference potential layer GND shown in FIG. 3 may be replaced with a pressure electrode for pressure detection. For convenience of description, the pressure electrode P shown in FIG. 3 is used as the first pressure electrode, and the pressure electrode replacing the reference potential layer GND is called a second pressure electrode. The amount of change in mutual capacitance according to a change in distance between the first pressure electrode P and the second pressure electrode may be received through one of the first pressure electrode P and the second pressure electrode to detect the touch pressure. have.

Meanwhile, although not illustrated in a separate drawing, the touch input unit 100 illustrated in FIG. 1 does not have a separate pressure electrode, and a driving electrode for driving the display module 150 or a touch of the touch sensor module 110. The touch pressure may be detected using a touch electrode for position sensing.

For example, the pressure electrode P of FIG. 3 may be a touch electrode of the touch input unit 100 of FIG. 1. A position of a touch input to the touch input unit 100 may be detected through the touch electrode P, and a change in mutual or magnetic capacitance due to a change in distance between the touch electrode P and the reference potential layer GND may be detected. To detect the touch pressure. Here, in order to detect the touch position and the touch pressure with one touch electrode P, two or more driving signals input to one touch electrode P (detecting the drive signal / touch pressure for detecting the touch position) Driving signals) may be applied separately from each other at different times.

The 42 and the third electrode 43 may be arranged such that the respective third electrodes 43 may be connected in a direction crossing the direction in which the second electrodes 42 extend, without intersecting with each other. have.

Since the first electrode 41 and the second electrode 42 or the first electrode 41 and the third electrode 43 are located on different layers, they may be implemented to overlap each other. For example, as illustrated in FIG. 5, the first electrode 41 and the second electrode 42 or the first electrode 41 and the third electrode 43 are each of the plurality of first axis electrodes 510 and the plurality of electrodes. The second axis electrode 520 of the, may be arranged to cross each other. Alternatively, as shown in FIG. 4, the rhombic first axis electrode 510 and the second axis electrode 520 may be located on different layers.

The first electrode 41 may be formed directly on the bottom surface of the cover 10. Similarly, the second electrode 42 and the third electrode 43 may be directly formed on the upper surface of the display module 150. In detail, the second electrode 42 and the third electrode 43 may be directly formed on the upper surfaces of the first substrate layers 151 and 161 of the display module 150 to be described later. In this case, the first electrode 41, the second electrode 42, and the third electrode 43 may be formed of a transparent conductive material (eg, indium tin oxide (ITO) or antimony tin oxide (ATO)). Can be. In addition, between the cover 10 and the first electrode 41, between the first electrode 41 and the compression layer 30, between the compression layer 30 and the second electrode 42 and the third electrode 43 or An insulating film (not shown) made of a thin transparent film made of plastic such as polyethylene terephthalate (PET) may be disposed between the second electrode 42 and the third electrode 43 and the display module 150. In this case, the insulating layer may serve to maintain the touch input operation by protecting the electrodes disposed under the cover 10 even if the cover 10 is damaged by an external impact. In this case, an optical clear adhesive (OCA) may be disposed between the insulating layer and the electrode or between the electrode and the compression layer 30 to be bonded to each other.

The compression layer 30 is composed of a material that is pressed when the pressure is applied to the cover 10 but returns to its original state when the applied pressure is released. The faster the recovery force, the higher the pressure detection accuracy can be. The compression layer 30 may be made of silicone, acrylic, or other compressible elastic body. Since the compression layer 30 is disposed on the display module 150, the compression layer 30 may be made of a transparent material so that the screen output from the display module 150 may be seen from the outside. have.

The first substrate layer 151 may be a color filter glass, and the second substrate layer 152 may be a TFT glass.

In this case, the display module 150A including the LCD panel may include a backlight unit (not shown) disposed under the second polarization layer 154. The display module 150A, which is an LCD panel, does not emit light by itself, but performs a function of blocking or transmitting light. Accordingly, a light source is positioned below the display module 150A to shine light on the display module 150A to express information having various colors as well as light and dark on the screen. Since the display module 150A, which is an LCD panel, does not emit light as a passive element, a light source having a uniform luminance distribution on the rear surface is required.

Hereinafter, a method of controlling the behavior of a character in a touch input device according to an embodiment of the present invention will be described with reference to the drawings subsequent to FIG. 16.

FIG. 16 shows the first behavior of the character ch when the object f touches a portion of the character ch being displayed on the display screen 101 at a pressure less than the first reference pressure Pth1. Drawing.

FIG. 17 shows a character when the object f touches a part of the character ch displayed on the display screen 101 at a pressure less than or equal to the first reference pressure Pth1 and less than the second reference pressure Pth2. The figure which shows the 2nd action of (ch).

FIG. 18 illustrates a third behavior of the character ch when the object f touches a portion of the character ch displayed on the display screen 101 at a pressure equal to or greater than the second reference pressure Pth2. Drawing.

16 and 18, the touch input device according to the embodiment of the present invention controls the behavior of the character ch displayed on the display screen 101 differently according to the magnitude of the pressure applied by the object f. can do. The behavior control of the character ch may be processed by the controller 500 of FIG. 1.

The controller 500 detects the touch position and the pressure magnitude of the object f input to the surface of the touch input unit 100.

The controller 500 determines whether the touch position of the detected object f is included in the position of the character ch being displayed.

When the detected touch position of the object f is included in the position of the character ch, the controller 500 determines a touch type according to the pressure magnitude of the object f. The touch type may be determined by using one or a plurality of predetermined reference pressures.

For example, as shown in FIGS. 16 to 18, when two reference pressures Pth1 and Pth2 are set in advance, the controller 500 determines that the pressure magnitude of the object f is less than the first reference pressure Pth1. The touch of the object f is determined as a light touch, and if the pressure of the object f is greater than or equal to the first reference pressure Pth1, the touch of the object f is determined as a force touch. can do.

Furthermore, the controller 500 determines that the touch of the object f is a soft force touch when the magnitude of the pressure of the object f is greater than or equal to the first reference pressure Pth1 and less than the second reference pressure Pth2. When the magnitude of the pressure of the object f is greater than or equal to the second reference pressure Pth2, the touch of the object f may be determined as a hard force touch.

The controller 500 may determine the behavior of the character ch according to the touch type of the determined object f.

For example, when the touch type of the determined object f is a simple touch, the controller 500 may control the character ch to perform a preset first action on the display screen 101. Here, the first action may be, for example, an action in which the character ch rides tickling.

When the touch type of the determined object f is a weak pressure touch, the controller 500 may control the character ch to perform a preset second action on the display screen 101. Here, the second action may be a different action from the first action, for example, an action in which the character ch seems to be loved.

When the touch type of the determined object f is a strong pressure touch, the controller 500 may control the character ch to perform a preset third action on the display screen 101. Here, the third action may be a different action from the first action and the second action, and may be, for example, an action in which the character ch is stuck or hit.

As described above, using the method of controlling the behavior of the character in the touch input device according to the embodiment of the present invention has an advantage of displaying various behaviors of the character according to the amount of pressure applied to the object f.

Referring to FIG. 19, different actions appear according to the light touch, the soft force touch, and the hard force touch described with reference to FIGS. 16 to 18. Specifically, in the case of a simple touch, the tickling behavior is expressed in the character, in the case of a weak pressure touch, the beloved behavior is expressed in the character, and in the case of a strong pressure touch, the stabbed or hit behavior may be expressed in the character.

As described above with reference to FIGS. 16 to 18, the controller 500 illustrated in FIG. 1 may control the behavior of the character ch according to the touch type. Here, the controller 500 may control the behavior of the character ch according to the touch time of the object f as well as the touch type of the object f. Specifically, an example will be described with reference to FIG. 19.

Referring to FIG. 19, when the touch of the object f is a weak pressure touch, the controller 500 controls the character ch to perform a second action (lovely). However, the controller 500 may control the second action to appear when the touch time Ta-Tb of the object f is within a preset first reference time range. To this end, the controller 500 may detect the touch time together with the touch position and the magnitude of the pressure of the object f.

If the touch time of the object f exceeds the first reference time range, the controller 500 may control the character ch to perform an action different from the second action lovely. For example, the character ch may be controlled to be in a default state where no action is performed, or the character ch may be controlled to perform annoying behavior.

Also, the touch time may be considered even when the touch of the object f is a strong pressure touch. As illustrated in FIG. 19, when the touch time Tc-Td of the object f is within a preset second reference time range, the controller 500 determines that the character ch has a third action (poke or punch). Control to be performed. However, if the touch time of the object f exceeds the second reference time range, the controller 500 may control the character ch to perform an action different from the third action. For example, the character ch may be controlled to be in a basic state in which no action is performed or the puncture and punching actions applied to the character ch may be continuously performed.

As described above, according to the method of controlling the behavior of the character in the touch input device of the present invention, the behavior of the character ch can be controlled not only according to the touch type of the object f but also by the touch time of the object f. There is an advantage.

Furthermore, the method of controlling the behavior of the character in the touch input device of the present invention may control the behavior of the character ch according to the touch position of the object f. 16 to 19, the method of controlling the behavior of the character ch by the touch type of the object f or the behavior of the character ch by the touch type and the touch time has been described. In the above two methods, the action of the character ch may be controlled by further considering the touch position of the object f.

The control unit 500 determines the touch position of the object f, and by using the control unit 500, the touch position of the object f differs depending on a predetermined position of the character ch. Can be controlled to be performed. For example, as illustrated in FIGS. 16 to 18, when the touch position of the object f is the face of the character ch, the controller 500 may determine the character according to the above-described touch type and / or touch time. control the behavior of (ch) However, when the touch position of the object f is the body of the character ch, the controller 500 may display a different action than the case of touching the face described above even if the touch type and the touch time are the same. ch) can be controlled. As a specific example, when the object f touches the body of the character ch with a weak pressure touch, the controller 500 may control the character ch to perform a tickling behavior more than the simple touch. Can be.

As described above, using the method of controlling the behavior of the character in the touch input device according to the embodiment of the present invention, in addition to the touch type and / or touch time, the behavior of the character ch can be controlled according to the touch position. There is this.
