Description

Technical Field [0001] The present invention relates to an information input device for three-dimensional shape design and a three-dimensional image generation method using the same,

The present invention relates to an information input device for three-dimensional shape design and a method for generating a three-dimensional image using the same. More particularly, the present invention relates to a three- And a method for generating a three-dimensional image using the apparatus.

Various tools have been developed to produce desired images using a computer, and these tools usually provide a way to produce three-dimensional images. Similar to the method of producing a two-dimensional image, a keyboard and a mouse are used as a main input device in producing a three-dimensional image. The method of inputting through the keyboard and the mouse is to designate a specific position of the original image using a mouse and then draw a line using the keyboard with respect to that position to create a desired image.

However, this method has a disadvantage in that a large number of operations are required to process a part of the image, and the workload of the user is very large. Furthermore, this method is suitable for creating an accurate image after a certain level of design is completed by a hand draft or the like. For example, it is suitable for a method of finishing an artwork which is not stereotyped, not.

In order to solve such a problem, an information input device in the form of a three-dimensional structure equipped with a touch sensor or a pressure sensor is provided to press a specific part of the structure so that a desired part of the original image can be depressed There is a suggestion.

Japanese Patent Laying-Open No. 2002-032173 (Information Input Device) discloses an information input device in which a basic structure is made of a gel-like material and a pressure applied to the basic structure and a sensing means for sensing a point and a time at which the pressure acts . When a user inputs a command for a desired operation in a manner such as pressing a basic structure by hand, the three-dimensional shape is deformed with respect to the corresponding point in the current image displayed on the screen.

U.S. Patent Application Publication No. US2015-0067560 discloses a technology for removing a graphic object or controlling the appearance of a graphic object according to the intensity when a preset contact intensity is generated in a virtual input device capable of sensing touch and pressure .

Korean Patent Laid-Open Publication No. 2002-0073890 (a three-dimensional modeling system using a casting of a hand and a method thereof) forms a virtual hand or a finger having the same movement and shape as a user's hand or finger in a virtual space, And a spatial region in which a virtual object and a virtual hand or a finger are in contact with each other according to the movement and shape of the finger are calculated and transformed as much as the calculated virtual object.

Korean Patent Publication No. 2010-0119940 (an apparatus and method for generating three-dimensional content in a portable terminal) provides a authoring tool for creating three-dimensional content in a portable terminal. When the pressure for deforming the three-dimensional object is applied to the touch pad on the screen, the conversion value according to the pressure intensity is confirmed and applied to the three-dimensional object.

Such conventional techniques have the following problems.

Conventional techniques suggest a method of shaping a shape by manually manipulating an information input device by a user. However, this method merely suggests a manipulation method for depressing any direction, and does not provide a manipulation method for protruding. Therefore, it is impossible to perform a process of protruding a part in the shape of the original image, or it must be executed through a very complicated manner of operation.

In addition, the prior art uses a touch sensor alone or only a touch sensor and a pressure sensor to determine a touched position and a position and degree of a strain through pressure at the touched position. Therefore, it is not possible to provide a variety of input manipulation methods that are convenient for the user for the same one transformation operation.

In addition, the prior art fails to provide an effective input method of various control commands when the user intends to execute any control command on the original image. For example, when the user wishes to change the direction in which the current original image is displayed on the screen, rotates the original image to be displayed, or enlarges / reduces the displayed original image, the user can input additional additional input devices Keyboard, mouse, etc.).

In addition, the prior art is not free to switch the operation mode. For example, when a user continues work to depress various parts of an original image, and then switches to an operation of projecting another part, a separate additional input device should be used.

FIG. 1 is a diagram showing a state in which an information input apparatus 100 for a 3D shape recognizer according to the present invention is used for transformation processing of an original image 210 displayed on a screen.

The information input apparatus 100 according to the present invention is connected to a computer so as to be capable of data communication in a wired or wireless manner and displays an original image 210 on a screen of a monitor 200 of a computer, . When the information input apparatus 100 is deformed by the user's manipulation by hand, a deformation corresponding to the deformation applied to the information input apparatus 100 is applied to the original image 210, . The original original image 210 may be, for example, a shape of a spherical object or a shape of a cylindrical object.

FIG. 2 is a block diagram showing the detailed configuration of the information input apparatus 100 of FIG. 1, and FIG. 3 is a diagram schematically showing the physical configuration of the information input apparatus of FIG.

The information input apparatus 100 according to the present invention includes a structure 160, a touch sensor 110, a pressure sensor 120, an inertial sensor 130, a tension sensor 140, and an interface 150.

The structure 160 is made in a predetermined size suitable for grasping by a user. The shape of the structure 160 may be any shape, but it is preferable that the structure 160 is formed in a spherical shape or an egg shape so that the outer surface of the structure 160 has an even shape. The structure 160 may be made of, for example, a soft material such as silicon or another material, and may have a restoring force that is restored to a circular shape within a short period of time after the user presses the outer surface of the structure 160.

The touch sensor 110 detects the touch position, which is the point where the structure 160 is touched by being installed on the outer surface of the structure 160. An object to be sensed by the touch sensor 110 is a touch of a user's hand or a finger, or an auxiliary tool such as a stylus pen. The touch sensor 110 may be configured to include a hovering sensor. In addition to the direct contact of the sensor surface, the hovering sensor senses the approach of an external object in a noncontact state by sensing an object approaching the sensor surface within a certain distance.

The pressure sensor 120 is installed on the outer surface of the structure 160 to sense the pressure applied to the structure 160. The pressure sensor 120 senses the pressure that the user presses on any part of the structure 160 and generates a signal therefor.

The inertial sensor 130 is installed in the structure 160 to sense the movement of the structure 160 in space. The inertial sensor 150 may comprise, for example, a gyroscope. The inertial sensor 130 preferably includes a sensor capable of detecting the movement of the structure 160 in the vertical and horizontal directions as well as the rotational direction.

The tensile force sensor 140 is installed on the structure 160 and senses the tension in the plane direction applied to the outer surface of the structure 160. 4 is a view for explaining an object to be sensed by the tension sensor. When a user grasps and pulls one part of the surface of the structure 160 with two fingers, Lt; / RTI > The tension sensor 140 senses the magnitude of the force pulled in the surface direction.

The interface 150 provides a path for transmitting signals sensed by the touch sensor 110, the pressure sensor 120, the inertial sensor 130, and the tension sensor 140 to a computer. The interface 150 is connected to the communication interface of the computer so as to be capable of data communication, and both wired and wireless connections are possible, but a wireless connection is more preferable.

Hereinafter, a method of generating a three-dimensional image by processing an original image 210 using the information input apparatus 100 having such a configuration will be described. FIG. 5 is a flowchart illustrating a method for generating a three-dimensional image according to the present invention performed by the configuration of FIG.

The computer receives signals of the various sensors 110, 120, 130 and 140 from the interface 150 and various sensors 110, 120, 130, and 140 sensed by the user operating the information input apparatus 100, Several patterns (first to third input patterns) are predefined for the signals of the sensors 110, 120, 130, and 140 (S310). Signal or a combination of signals from two or more signals.

The computer receives a signal from the information input apparatus 100 in a state where such a pattern is defined and stored (S320). The computer analyzes the received signal to determine whether it is a signal corresponding to a predefined pattern (S330). If the pattern is a predefined pattern, the original image 210 is processed according to a command defined for the pattern, or a direct control operation on the original image 210 or a processing operation on the original image 210 And performs various control operations required additionally (S340)

By repeating this process until the desired image is completed, the user can generate a three-dimensional image of a desired shape.

In the present invention, a user's operation pattern for the information input apparatus 100 is defined as a first input pattern to a third input pattern.

The first input pattern is a pattern defining a depression command for one part of the original image 210 with respect to a signal including one or two or more of the signals from the touch sensor 110 and the pressure sensor 120. The second input pattern is a pattern that defines a protrusion command for one part of the original image 210 with respect to a signal including one or two or more of signals from the touch sensor 110 and the pressure sensor 120. [ The third input pattern is a pattern defined by a predetermined control command related to the control of the machining operation of the original image 210 with respect to the signal including the signal from the inertia sensor 130. Here, the control command may be a command for the original image 210 itself, such as movement on the screen of the original image 210, rotation or enlargement / reduction, and the like, And a switching instruction for an operation mode for recognizing the operation mode. 5, when a first input pattern or a second input pattern is input, the computer determines whether a specific portion of the original image 210 formed in a predetermined three-dimensional shape is depressed The shape of the original image 210 is modified so as to protrude, and when the third input pattern is input, a control operation conforming to the third input pattern is performed.

Hereinafter, various command input methods input through the information input apparatus 100 of FIG. 1 will be described with reference to FIGS.

6 is a diagram illustrating a method of inputting a first input pattern for inputting a depression command. When the user presses a specific part of the information input device 100 using the finger, the touch sensor 110 and the pressure sensor 120 generate a sensing signal as the structure 160 of the information input device 100 is depressed and deformed . Accordingly, the pushing pressure is sensed by the position touched by the touch sensor 110 and the pressure sensor, and the two sensors 110 and 120 generate a signal. That is, the touch sensor 110 defines a depression point and the pressure sensor 120 defines a depression degree. The signals generated by the two sensors 110 and 120 are transmitted to the computer via the interface 150 so that a corresponding depression of the original image 210 is applied at a corresponding position.

7 is a view showing a state in which the information input apparatus 100 is operated so that two points are concurrently depressed. When the information input apparatus 100 is operated so that two points are concurrently depressed, a line connecting two points is defined to be recessed. Therefore, the user can designate the depression area with respect to the area determined by the connecting line segments of the two points and process the depression shape on the line by one operation.

8 shows a state in which the information input apparatus 100 is operated so that three points are concurrently depressed. When three or more points are concurrently recessed, a surface having a width on the outer surface of the information input apparatus 100 is defined by lines connecting depressed points. When three points are depressed as shown in FIG. 8, a triangular region as shown in FIG. 9 is defined. Accordingly, the original image 210 is subjected to the depression transformation for the region defined by the triangle. 8 and 9, it is also possible to define the desired area by continuously dragging the outer surface of the information input apparatus 100 in the form of a desired graphic. That is, the user can define the depression area by continuously drawing the shape of the triangle as shown in FIG. 9 using the single finger, without removing the finger from the outer surface of the information input apparatus 100. According to this method, the depression region can be freely defined in a desired size and shape.

On the other hand, the touch point sensed by the touch sensor 110 can be computed as one point in theory, but in reality, a region having a predetermined size including the touched point is touched. The touch region itself may be defined as a recessed region. For example, when the user touches the information input device 100 with a sharp stylus pen, a very small area is detected as a touch area when the information input device 100 is touched with a finger. Therefore, when the actual touched area is defined as a depression area, the user can vary the touch area by changing the touching tool or the touching method at the time of touching the information input apparatus 100, It is possible to input a depression command for an area having a desired extent.

As described above, the second input pattern is defined as a pattern for inputting the protrusion command. At this time, the protrusion command can be defined in the same manner as in the above-described first input pattern. 6 to 9 and the modified examples thereof are for the depression command, but the depression point is defined as the protrusion point with respect to the signal from the touch sensor 110 and the protrusion point is protruded from the signal from the pressure sensor 120 , It is possible to define that the manipulation of the same type is recognized as a protrusion command. Similarly, a protruding region can be defined for a touch region sensed by the touch sensor 110 or an area determined by a plurality of points.

In this case, since the same method is applied to the point or area to be deformed and the extent of deformation, a separate command for switching the operation mode is required for whether it is a depression command or a protrusion command. The operation mode can be switched by using a separate additional input device (for example, a keyboard or a mouse), or by defining a different mode of operation for the information input device 100 itself as a mode switching command, (100). Various examples of the operation of the information input apparatus 100 for switching the operation mode will be described later.

FIG. 10 shows an example of a second input pattern defined for inputting a protrusion command in a manner different from a depression command. In Fig. 10, the second input pattern is defined as a protrusion command at this specific point for a drag signal converging to a specific point at a plurality of spaced points sensed by the touch sensor 110. [ That is, the user touches the two fingers on the surface of the information input device 100 and then simultaneously drags the two fingers in a direction approaching each other from the initial touch point. 10, the index finger is dragged by S1 length and the thumb is dragged by S2 length in a state where the index finger and the thumb are in contact with the information input device 100 at the same time, . For such an operation, it is defined as a protrusion command which causes the section of the length defined by d1 to protrude outward. At this time, the length of S1 and the length of S2 may be respectively detected and defined as an input to the degree of protrusion. For example, when the length of S2 is longer than the length of S1, the original image 210 is deformed so that the degree of protrusion in a section closer to the thumb is larger than a section near the index finger in the section d1.

Fig. 11 shows an example in which a scheme similar to Fig. 10 is applied to a triangular area determined by three points. When three points are dragged to converge inward with three fingers in contact, they are defined as protruding regions for the triangular region defined by the drag end point of the drag signal. At this time, the degree of protrusion can be defined with respect to the drag length of the drag signal, and the magnitude of the extrusion degree can be defined to be different with respect to the refresh of each drag length.

Fig. 12 shows an example in which a hovering sensor is employed as the touch sensor 110. Fig. The hovering sensor may be integrally formed so that the touch sensor 110 is included as a part of the function, or may be additionally provided as a separate sensor in addition to the touch sensor 110. In the case where the hovering sensor is provided, it is possible to correspond to a second input pattern defining the protrusion command in a more various manner of operation than the protrusion command.

As shown in FIG. 12, the user performs an operation similar to that shown in FIG. 10 at a position spaced from the surface of the information input apparatus 100 by a predetermined distance. This movement is sensed by the hovering sensor, and the hovering signal generated by the hovering sensor is defined as an overhang command. 12, the application of the definition of the protruding area, the definition of the degree of protrusion, and the like to this operation can be similarly applied to all of the modifications described with reference to Figs. 10 and 11. Fig. In other words, if the hovering signal is a drag signal that converges to a specific point at a plurality of spaced points, it can be defined as a protrusion command at a specific point. Also, as a result of the operation shown in FIG. 12, a section between the two points at which the final drag ends is defined as a protruding area. At this time, the drag length of the drag signal can define the degree of protrusion, and when the drag length of each drag line is different, the degree of protrusion can be defined to be different for each part in the protrusion area.

13 is a diagram showing an example in which a second input pattern can be defined in a different manner when a hovering sensor is employed. That is, the second input pattern is a pattern defined as a protrusion command for the case where the hovering signal is a separation signal away from the surface of the hovering sensor. The user places the two fingers in a position very close to the surface of the information input apparatus 100 and then separates the two fingers from the surface of the information input apparatus 100. [ The hovering sensor generates a separation signal by this separation operation, wherein the interval (d2) between the positions of two fingers at first defines a protrusion area. Also in this case, similarly, the protruding area using three or more fingers can be defined as a plane area having a predetermined shape. In addition, the user may initially make two or more fingers touch the surface of the information input device 100 and then perform the spacing operation. In this case, two or more fingers may be defined as protruding areas have. As described above, in this embodiment, a hovering region sensed before the generation of the separation signal or sensed by the starting point of the separation signal or an area determined by a plurality of points is defined as the projection region.

FIGS. 14 and 15 illustrate how the user first inputs the protrusion command using the hovering sensor after defining the protrusion area.

As shown in FIG. 14, the user draws a desired figure (triangle in FIG. 14) on the surface of the information input apparatus 100 using one finger. Accordingly, the protruding area is first defined according to the signal sensed by the touch sensor 110. [ Then, the user performs a separation operation to move the entire palm to the surface of the information input apparatus 100, as shown in Fig. This separation operation is detected by the hovering sensor, and is recognized as a protrusion command for the previously selected protrusion area as shown in Fig.

Meanwhile, as described above, the information input apparatus according to the present invention may further include a tension sensor 140. As shown in FIG. 16, when the user grasps the surface of the structure 160 of the information input apparatus 100 using two or more fingers and pulls inward to approach each other, the surface of the structure 160 is pulled And the tension sensor 140 senses such a tension. At this time, the protruding region can be defined by a plurality of points sensed by the touch sensor 110 or a convergence point of the tension direction sensed by the tension sensor 140. In Fig. 16, A3 is a protruding region defined by an area between two fingers sensed by the touch sensor 110. [ In this case also, in a manner similar to the above-described embodiments, the magnitude d3 of the tension shown in Fig. 16 can define the degree of protrusion. Further, in this embodiment, the signal from the pressure sensor 120 can be defined as the degree of protrusion. In this case, the tension sensor 140 detects that the tension is applied only to the input of the protrusion command The magnitude of the tension itself is treated as irrelevant to the degree of extrusion.

As described above, the third input pattern defines various control commands, and in the present invention, the control command is defined with respect to the signal including the signal from the inertial sensor 130. [ The inertial sensor 130 can detect the movement itself in the space of the information input apparatus 100 so that the rotation of the information input apparatus 100 or the movement in the horizontal / It can be defined as a movement command in the same way on the screen.

When the information input apparatus 100 itself is moved to the left as shown in FIG. 17, the original image 210 moves to the left on the display screen of the monitor 200.

As an example of the movement command, the rotation command may be included. As shown in FIG. 18, when the information input apparatus 100 itself is rotated, the rotation is detected by the inertial sensor 130, and the original image 210 is rotated at a corresponding angle on the display screen. Accordingly, the user can rotate the original image 210 in a desired direction, and then perform a desired deformation processing operation on the original image 210 again.

Meanwhile, the third input pattern defined using the inertial sensor 130 may include a magnitude change command on the display screen of the original image 210. For example, as shown in FIG. 19, an operation of moving the information input apparatus 100 to the right and then moving it to the left is defined as a command to increase the size of the original image 210, The size of the original image 210 may be defined as a size reduction command. As a result, the display state of the original image 210 is enlarged or reduced, and the user can enlarge the local region to perform precise processing or reduce the size again so as to view the entire image.

Meanwhile, the third input pattern may include a pattern defined by a mode switching command between the first input pattern and the second input pattern with respect to the signal from the inertial sensor 130. As an example, the operation as shown in FIGS. 19 and 20 can be defined as a depression command input mode and a protrusion command input mode, respectively, without defining them as an enlargement / reduction command. According to this method, for example, the first input pattern for the depression command and the second input pattern for the protrusion command are defined in the same pattern, and only the depression or protrusion can be determined through mode switching. In this case, it is defined in the same manner as the depression / protrusion area and the depression / protrusion degree, and whether or not the machining order corresponding to the corresponding area is the depression command or the protrusion command is determined by the inertia sensor 130 of the information input apparatus 100, Lt; / RTI > signal. Therefore, the user can perform depression or protrusion deformation processing in a simplified operation mode.

On the other hand, while the user is using the information input apparatus 100, the information input apparatus 100 has to move its position in the space itself little by little. In consideration of this point, the inertial sensor 130 recognizes the motion command, the magnitude change command, the mode change command, or the like because the inertial sensor 130 simply defines the motion detection of the information input apparatus 100 It is preferable to define the condition that the size sensed by the inertial sensor 130 becomes a predetermined value or more as an additional condition.

According to a preferred embodiment of the present invention, in addition to the first to third input patterns, a fourth input pattern may be additionally provided. Here, the fourth input pattern is preferably defined by a combination of signals including signals from at least one of the touch sensor 110 and the pressure sensor 120.

The fourth input pattern may be a mode switching command between the first input pattern and the second input pattern. The mode change command is the same as the command for determining whether the mode is the protrusion command input mode or the depression command input mode as described above. The difference from the above case is that the mode change command is only for the signal from the inertial sensor 130 Or a signal from the touch sensor 110 or the pressure sensor 120 together with a signal from the inertial sensor 130 or a combination signal thereof is defined.

In addition, the fourth input pattern may be a movement command or a magnitude change command for the original image 210 as described above. In this case, the difference may be determined by additionally using the touch sensor 110 and / or the pressure sensor 120 .

At this time, the additional signal for defining the fourth input pattern may be a sensing signal for a specific point from the touch sensor 110 or a sensing signal for a predetermined width or more, or may be a predetermined signal from the pressure sensor 120 May be a detection signal for

Fig. 21 shows an example of this case. When the user holds the whole of the information input apparatus 100 using the entire palm of both hands, the touch sensor 110 senses a touch on a very wide area. This state may be defined as a fourth input pattern. In this state, as shown in FIG. 19, a fourth input pattern may be defined for an operation of swinging the information input apparatus 100 to the left and right as shown in FIG. In a similar manner, for the operation of pressing a not-shown but predetermined one specific point over a predefined specific intensity, or in conjunction with such operation, the information input device 100 For a fast rocking motion, it may be defined as a fourth input pattern.

In the above embodiment, the depression / protrusion position or the area where the original image 210 is processed depends mainly on the signal from the touch sensor 110 in accordance with the depression command and the protrusion command. Alternatively, or in parallel thereto It may be configured to receive the depression / protrusion position or area from a separate auxiliary input device.

For example, when a cursor or a cursor on the screen is moved using a mouse to designate a specific point or a specific area is set, a position or an area is designated. In this way, when a position / area is designated by a mouse, And only the degree of depression / protrusion is determined without separately determining the depression / protrusion position. According to this method, for example, since a user can precisely designate a detailed area while viewing the screen, it is easy to finely finish the roughly finished image.

As described above, according to the present invention, the user can easily perform the depression work and the protrusion work for the original image by various manipulation methods in the work of producing the three-dimensional stereoscopic image. Further, in the three-dimensional image generation operation, it is possible to detect various deformation operations using various sensors, and various control commands to the original image itself can be easily input.
