As shown in the figure, the contact portion 202 may be formed in a conical shape taper away from the body portion 201.

As shown in FIG. 5A, the contact parts 220, 220 ′ and 220 ″ are formed of an elastic body and bent in a direction perpendicular to and corresponding to the direction of the body part 201 according to the direction and magnitude of the external force.

Thus, as shown in Figure 5b, the angle and distance between the surface of the touch sensor and the body portion 201, the stylus 200 is in a direction perpendicular to the surface of the touch sensor due to the reaction of the force pressing the surface of the touch sensor The shape of the contact portion 202 is changed according to the force and the friction force generated by the movement of the stylus 200 in contact with the surface of the touch sensor.

Accordingly, as shown in FIG. 5C, the size and shape of the contact surfaces 291 and 292 in contact with the surface of the touch sensor are changed as a result. 5D shows that the shape of the contact surfaces 293 and 294 is changed by the frictional force 295 generated by the movement of the stylus 200 in contact.

6 is a cross-sectional view of a contact portion 202 formed of a conductor, in accordance with one embodiment of the present invention.

As shown in FIG. 6A, the contact portion 202 may be formed of an elastic body which is a non-conductor, and the outer circumferential surface 221 may be coated with a conductive material. Alternatively, as shown in Figure 6b, it may be formed by injecting a flexible thin film 223 formed in a conical shape and a flexible conductor 224 therein.

In addition to the conductor, the body portion 201, the lid portion 230, and the contact portion 202 may use a dielectric having a high dielectric constant.

The dielectric is composed of a dielectric material such as liquid alcohol or water having a high dielectric constant in the sealed film 223. Alternatively, in order to further increase the dielectric constant, a solid (high dielectric) having a high dielectric constant such as barium titanate and lotel salt is dissolved in a solvent such as water or alcohol to make a dielectric material and put it in the membrane 223. Alternatively, materials such as barium titanate and lotel salt having a high dielectric constant may be dissolved and used in a predetermined form, or may be manufactured by mixing them with an elastic object such as silicon. As described above, when a dielectric having a constant dielectric constant is formed in a liquid form or a liquid in which a solid having a high dielectric constant is melted, the liquid may be discharged by adjusting the dissolved density using a sponge, pulp, or fiber material that may be infiltrated. The capacitive touch panel can match the most appropriate dielectric constant that can be reacted. The film 223 is made of an elastic material. For example, the film 223 is made of rubber, vinyl, silicon, and the like to accommodate a liquid dielectric material therein.

As shown in FIG. 7A, the contact portion 202 may be formed of several strands of conductive conductive fibers. The fiber may be a carbon fiber. Each of the fibers is bent in accordance with the external force, and when the external force is lost, it is elastic to return to its original shape. As shown in FIG. 7B, the coupling part 240 bundles and fixes several strands of fibers and electrically connects the fibers and the body portion 201.

8 is a flowchart illustrating a process of processing a touch input of the stylus 200 in the terminal 100 according to an embodiment of the present invention.

As described above, the terminal 100 includes a user input unit 130, a display unit 151, a memory 160, a controller 180, and the like. The display unit 151 may be a touch screen 151 having a layer structure with the touch sensor (hereinafter, the display unit 151 will be described as the touch screen 151).

The user sets the brush touch input mode through the user input unit 130 and the touch screen 151 of the terminal 100 (S110). The brush touch input mode refers to a state in which a font, a picture, or the like can be drawn by coloring according to the contact shape of the stylus 200 and the touch screen 151 (hereinafter, referred to as “butter touch”) according to the present invention. The brush touch input mode may be set by executing an application related to a picture, a game, a message, and the like.

When the brush touch input mode is set, the controller 180 displays an area 310 for inputting a brush touch on the touch screen 151 (hereinafter referred to as a canvas) (S120). Until the user input for ending the brush touch input mode is detected (S160), the touch screen 151 continuously detects a touch input to the canvas. When the brush touch is input to the canver (S130), the controller 180 analyzes a signal output from the touch screen 151 to identify the contact area 320 (S140). The contact area 320 refers to an area corresponding to a contact surface on which the surface of the touch screen 151 and the stylus 200 directly contact each other. The controller 180 analyzes a signal output to the touch screen 151 to identify a coordinate, an area, a shape, a direction, and the like of the contact area 320. The controller 180 displays the identified area by coloring the predetermined color and shades (S150).

The controller 180 repeats the processes S130 to S150 at predetermined intervals. That is, the brush touch input detects the brush touch input which is continuously (in contact with the contact maintained) or discontinuously (contact is stopped and then touches again) according to a predetermined sampling period, and the contact area 320 corresponding thereto is detected. ) And color it. The controller 180 calculates or identifies a contact time, a moving speed, a start point, an end point, etc. of the contact area 320 using the coordinates, the area, the shape, the direction, and the like of the identified contact area 320.

Areas other than the canvas 310 of the touch screen 151 may also receive a touch input, and a function corresponding thereto may be executed according to the touched position.

When the brush touch input mode ends according to the user input (S160), the colored image is stored in the memory 160 (S170). The colored image may be transmitted by being included in a message such as an MMS.

9 is a conceptual diagram illustrating a contact area 320 according to an embodiment of the present invention.

In general, a touch screen has a coordinate of n * m. For example, if there are a total of 128 * 128 coordinates, a total of 16384 coordinate points exist. Accordingly, the coordinate points located on the contact surface between the stylus 200 and the touch screen 151 recognize the contact, and the controller 180 analyzes the signal output from the touch screen 151 to identify the contacted coordinate points. . The controller 180 sets the contact area 320 by using the location, number, arrangement, etc. of the identified coordinate points. Thus, the contact area 320 may not exactly match the contact surface where the actual stylus 200 and the surface of the touch screen 151 contact.

The pattern of the actual contact surface of the stylus 200 in the memory 160 (for example, when the brush is pressed perpendicularly to the surface of the touch screen 151, when it is pressed at an angle, when it is pressed sideways, when it is moved in contact, etc. The contact surface shape), and apply it to the coordinate points to set the contact area 320. Each pattern may be stored for more than one stylus 200, and the controller 180 applies corresponding patterns according to the stylus 200 used (or according to user selection). The controller 180 analyzes the pattern by using the position, number, arrangement, and changes of the contacted coordinate points (changes in the movement speed and acceleration of the stylus 200, and changes in the shape of the contact surface), and sets the contact area into a set shape accordingly. 320).

9 shows an example of the above-described pattern or the contact area 320 set accordingly. Conical stylus 200 forms an elliptical contact surface with one end pointed, so that corresponding contact region 320 may also be set in such a shape. Therefore, the controller 180 analyzes a signal output from the touch screen 151 to obtain a length Δl, a width Δw, a center coordinate (x, y), a direction θ, and apply the same to a corresponding pattern. To set the contact area 320.

FIG. 10 is a diagram illustrating a display of a touch screen 151 in a brush touch input mode according to an embodiment of the present invention.

The touch screen 151 displays the canvas 310, the pallets 330 and 331, and the fly 340. As described above, the canvas 310 is an area for receiving a brush touch. The palette area is an area for selecting the color to be colored and its shade. When the user touches a portion where a desired color and a joke are displayed, the color of the selected joke is displayed on the craze 340.

The touch screen 151 may display the bristles 350. The shape of the brush may be displayed as corresponding to the shape of the stylus 200 used. The bristles display the selected color and color, and the remaining amount of ink and the location of the food. This is described in detail later.

In addition to the touch screen 151, other soft keys such as a menu may be displayed.

11 and 12 are conceptual views illustrating that the contact region 320 is colored differently according to contact time according to an embodiment of the present invention.

Referring to FIG. 11, each of the contact areas 401, 402, and 403 is colored differently according to the contact time. For example, the contact area 401 is 50% of the set shade when the contact is made for 0.1 second, the contact area 402 is 75% of the set shade when the contact is made for 0.2 seconds, and the contact region 403 is at least 0.3 second. In one case, it is painted at a concentration equal to 100% of the set shade.

When the contact area 320 moves, the coloring concentration may be adjusted according to the moving speed of the contact area 320. The controller 180 calculates the moving speed of the contact area 320 and displays it in dark colors when the moving speed is slow and blurred when it is fast (see reference numeral 404).

Referring to FIG. 12, even when the contact region 320 moves at the same speed, the concentration of the contact region 320 may be differently colored according to the location of the contact region 320 and the moving direction of the contact region 320. The point located at the arrow 411 in the contact area 320 is included in the contact area 320 for a longer time than the point located at the arrow 410 even if moving at the same speed, so that the color is darker (see reference numeral 412).

As described with reference to FIGS. 11 and 12, each pixel (or one point) of the canvas 310 may vary according to the time when the pixel contacts the stylus 200 or the time included in the contact area 320. Each color concentration can be determined. Therefore, the controller 180 calculates the time that the pixel is included in the contact region 320 and determines the color density accordingly.

FIG. 13 is a conceptual diagram illustrating that an area to be colored is expanded according to a contact time according to an embodiment of the present invention.

When the contact region 320 is stopped for a certain time, the colored region outside the contact region 320 is gradually diffused. The diffusion distance is determined by the contact time * diffusion rate. The diffusion rate may be determined according to a set material or a user's selection. For example, the color area is enlarged when the vehicle is stopped for 0.2 seconds (see reference numeral 420), and far when it is stopped for 1 second (see reference numeral 421).

The colored area denoted by reference numeral 424 indicates the diffusion when the contact area 320 moves. The contact area 320 gradually slows down while moving from left to right. Therefore, when moving slowly, the contact time increases relatively, so that the spreading distance increases.

As described above, according to the time when each pixel (one point) is in contact with the stylus 200, that is, the time included in the contact area 320, the colored area is enlarged from one point to a circle, and each circle ( In particular, an outline formed by overlapping a circle enlarged from a point located at the edge of the contact area 320 becomes the colored area 424.

14 is a conceptual diagram illustrating that the coloring concentration decreases as the area to be colored increases or as time passes, according to an embodiment of the present invention.

When the stylus 200 touches the craze 340, the color concentration decreases according to the increase of the area to be colored or the passage of time until the craze 340 is touched again. When the touch input corresponding to the point where the rice 340 is displayed is detected, the controller 180 initializes the color concentration. That is, the color density is set to 100% 430 of the set color and shade. As the stylus 200 moves in contact with the canvas 310, the controller 180 calculates and accumulates the areas of the colored areas (including the diffused and colored areas). The controller 180 gradually decreases the color density as the color area is increased, and sets the color density to 0% 431 when the color area reaches a predetermined value so that the color is no longer colored. The current color density may be displayed on the touch screen 151. If the touch area 340 is touched again, the color concentration is initialized and the process is repeated. In addition, the coloring concentration may be reduced according to the time that elapses after the touch of the craze 340 or the moving distance of the contact area 320.

FIG. 15 is a diagram illustrating that the reduction speed of the color density and the color pattern are set differently according to the time and the contact area of the stylus 200 touching the boom 340 according to one embodiment of the present invention.

The total area that can be colored may vary depending on the time and contact area at which the stylus 200 touches the craze 340. When the craze 340 is touched, the brushes 350, 441, 442, and 443 are displayed on the touch screen 151. For example, when the contact is made with the brush upright, the tip turns black and is displayed and spreads as the contact time elapses. Each region to be diffused may have a different concentration (442). After a predetermined time elapses, the whole color turns black and is displayed. The controller 180 sets the total area (or moving distance and time) that can be colored and the speed of decreasing the color density before reinitialization according to the contact time. For example, in the case of contact 441 for a short time, the entire coloring area is made smaller and the reduction speed of the color density is set larger than in the case of contact 444 or more for a predetermined time.

The method described above may be equally applied according to the contact area of the contact area 320 to which the cramped 340 is touched. For example, if only the tip of the stylus 200 is slightly touched, that is, if the contact area 320 is small, the brush 441 is displayed, and the wider contact area 320 is the brush 442, The contact area 320 over the predetermined area displays the brush 443. If the contact state is maintained, the portion displayed in black is diffused as described above. The shade of the diffused area may be different from the shade of the area due to direct contact (see brush 442).

Depending on the time when the stylus 200 touches the crest 340 and the contact area, the contact areas 320 of the same shape may be colored in different shapes 444, 445, and 446. The colored shapes 444, 445, and 556 inside the contact area 320 correspond to the brushes 441, 442, and 443, respectively.
