The touch recognition apparatus 200 according to the first embodiment of the present invention illustrated in FIG. 2A includes a touch signal input unit 210, a gesture detector 220, a color detector 230, and a controller 240. . In this case, the gesture detector 220 may include a trajectory detector 221 and a thickness detector 222, and the color detector 230 may include a photo detector 231 and a controller 240. May include a first control unit 241 and a second control unit 242. The touch pen 250 may further include a touch pen 250 for receiving a touch signal by the user.

According to the present embodiment, a touch signal is input by the user to the touch recognition apparatus 200 through the touch signal input unit 210.

When the user performs a touch operation through the touch pen 250, at the same time as the touch operation, the light emitting diode 251 included in the touch pen 250 emits light having various wavelength values according to a user's selection. The touch signal having a may be input to the touch signal input unit 210. The user may select a touch signal having specific color information to be input through the button 252 formed at one end of the touch pen 250. When the user presses the button 252 to select a specific color, light having a wavelength value of the color is emitted from the light emitting diode 251 formed at the other end of the touch pen 250.

In this way, when the touch signal is input to the touch signal input unit 210, the touch signal is output to the color detector 230 and the gesture detector 220, respectively.

The gesture detector 220 detects gesture information of a touch signal. When the user performs a touch operation through a hand or a touch pen on the touch screen, the gesture information includes trajectory information that the user draws to input a control command on the touch screen and thickness information of lines forming the trajectory. That is, the gesture information refers to information including a trajectory (path) of a touch operation performed on the touch screen and a thickness of a line for drawing the trajectory in order for a user to input a touch signal. Hereinafter, in the present specification, gesture information is used as the above meaning.

The gesture detector 220 detects gesture information of a touch signal, and includes a trajectory detector 221 for detecting trajectory information for detecting trajectory information of a touch signal and a thickness detector for detecting thickness information of a touch signal. 222.

The trajectory detecting unit 221 may detect the trajectory of the touch signal input by the user, and may detect the trajectory of the touch signal through the coordinate value of the touch signal. Also, when the touch signal input by the user is made of a line, the thickness detecting unit 222 recognizes the thickness of the line. Although the thickness detecting unit 222 may recognize the thickness of the touch signal input to the touch screen through coordinate values, the thickness information may be selected by the user through the button of the touch pen 250 together with the color information. It may be. The gesture information including the trajectory information and the thickness information of the touch signal detected by the trajectory detection unit 221 is input to the controller 240.

The color detector 230 detects color information of the touch signal, and according to the present embodiment, may include a photo detector 231. The photo detector 231 detects light and detects light and converts the light into an electronic signal, thereby reading the wavelength value of the light incident on the photo detector 231. Thus, as described above, the color detector 230 including the photo detector 231 may detect color information of the touch signal input as light having a specific wavelength value. A touch signal in the form of a light having a specific wavelength value is input to the touch signal input unit 210 through the touch pen 250, wherein light having a specific wavelength value includes color information of the touch signal. The light has various colors according to the wavelength value. By using this principle, the light wavelength value is calculated through the photo detector 231, so that color information of the touch signal can be detected.

The gesture information of the touch signal detected by the gesture detector 220 and the color information of the touch signal detected by the color detector 230 are input to the controller 240. The controller 240 generates a control command signal according to the input gesture information and color information, and outputs the control command signal to the terminal including the touch recognition apparatus 200 according to the present embodiment.

As shown in FIG. 2A, the controller 240 according to the present exemplary embodiment may include a first controller 241 and a second controller 242. The first control unit 241 generates a first control command signal corresponding to the gesture information of the touch signal, and the second control unit 242 generates a second control command signal corresponding to the color information of the touch signal.

The first controller 241 generates a first control command signal according to the gesture information detected by the gesture detector 220. For example, when a user inputs a touch signal having a red triangular shape (assuming that thickness information is not input separately), the gesture detector 220 has a triangular (△) trajectory. To detect that. When the gesture detecting unit 220 outputs such gesture information to the first control unit 241, the first control unit 241 may output a first control command signal corresponding to the gesture information of the triangle Δ, for example, playback ( Play) Generates a first control command signal for commanding an operation. The gesture information may vary according to the shape of the trajectory, and the first controller 241 according to each gesture information, each commanding a control operation to the terminal used by the touch recognition device 200 according to the present embodiment Generate a first control command signal.

The second controller 242 generates a second control command signal according to the color information detected by the color detector 230. For example, as described above, when the user inputs a touch signal having a red triangle (△) shape (assuming that thickness information is not input separately), the color information detector 230 may set the wavelength value of the touch signal. It reads and detects that the color information of the input touch signal is red. When the color sensor 230 outputs such color information to the second control unit 242, the second control unit commands a second control command signal corresponding to red color, for example, to operate at a speed of 2 times. Generate a second control command signal. The color information may vary according to the wavelength value, and the second control unit 241 controls the second control unit to instruct a control operation to the terminal in which the touch recognition apparatus 200 according to the present embodiment is used according to each color information. Generate a command signal.

In this case, the first control command signal and the second control command signal generated by the first control unit 241 and the second control unit 242 are included in one control command signal. As described above, the second control command signal is a control command signal embodying the first control command signal and may be a command signal embodying any one of speed, intensity, and range of the first control command signal. . That is, as described above, when a touch signal having a red triangular shape (△) is input, the first control command signal is configured to reproduce the operation, and the second control command signal specifies the speed of the first control command signal. Command the speed operation to the terminal. Therefore, when the control command signal including the first and second control command signal is output from the control unit 240 to the terminal, the terminal performs the double speed playback operation.

As such, the second control command signal is a command signal embodying the first control command signal and may represent any one of speed, intensity, and range of the first control command signal. When the first control command signal indicates an erase operation, the second control command signal commands the range of the file, and the control command signal including the first control command signal and the second control command signal is transmitted to the terminal. If input, the terminal deletes all files. As described above, the second control command signal generated corresponding to the color information can be used to input more specific and various control command signals to the terminal.

In addition, as described above, the gesture information may include trajectory information and thickness information of the touch signal, and thus, various first control command signals may be generated by various combinations of the trajectory information and the thickness information.

As described above, by sensing the color information of the touch signal, various control command signals can be generated using only the touch signal through the touch recognition apparatus according to the present invention, which can generate more various control command signals.

Therefore, duplicate descriptions are omitted and briefly review the differences.

According to the present exemplary embodiment, a touch signal having color information selected by the user is input to the touch recognition apparatus 300 through the touch signal input unit 310. Before the touch signal of the present embodiment is input to the touch signal input unit 310, color information of the touch signal is determined by the user in the touch palette unit 330. The touch palette unit 330 includes menus representing a plurality of color information. When a menu representing specific color information is selected by the user, the specific color information selected by the user is transferred to the touch recognition apparatus 300. Is entered.

The touch palette unit 330 will be described in more detail with reference to FIG. 7, but includes menus representing various color information such as red, yellow, green, blue, and purple. When the user selects a menu showing a specific color among the plurality of menus, color information of a touch signal to be input by the user later is determined by the user's selection. That is, instead of reading the wavelength value of the touch signal and detecting the color information as in the first embodiment described above, before the user inputs the touch signal to the touch signal input unit 310 through the touch screen, the touch palette is previously displayed. The color information of the touch signal to be input is determined by selecting color information of one of the menus representing the plurality of color information included in the unit 330. As such, the color information selected by the user, which is input to the touch palette unit 330, is input to the controller 240 later. In this case, the color information may be RGB color information including red information, green information, and blue information.

The touch signal input unit 310 receives a touch signal having color information selected by the user through the touch palette unit 330. The touch signal input to the touch signal input unit 310 is input to the gesture detector 320, and the gesture detector 320 detects gesture information of the touch signal. As described above, when the user performs a touch operation using a hand or a touch pen through a touch pen on the touch screen, the gesture information is a trace drawn by a user for inputting a control command on the touch screen, or the thickness of a line forming the trajectory. May contain information.

The gesture detector 320 may include a trajectory detector 321 for detecting the trace information of the touch signal and a thickness detector 322 for detecting the thickness information of the touch signal. The trajectory detection unit 321 detects information on the trajectory of the touch signal input by the user, and may detect the trajectory of the touch signal through the coordinate value of the touch signal. In addition, the thickness detector 322 detects the thickness of the touch signal input by the user. The thickness detector 322 may detect the thickness of the touch signal through coordinates of the touch signal or by receiving thickness information selected by the user from the touch palette. The gesture information including trajectory information and thickness information of the touch signal sensed by the trajectory detector 321 is input to the controller 340.

The gesture information of the touch signal detected by the gesture detector 320 and the color information of the touch signal detected by the color detector 330 are input to the controller 340. The controller 340 generates a control command signal according to the input gesture information and the color information, and outputs the control command signal to the terminal including the touch recognition device 300 according to the present embodiment.

As illustrated in FIG. 3, the controller 340 according to the present exemplary embodiment may include a first controller 341 and a second controller 342. The first control unit 341 generates a first control command signal corresponding to the gesture information of the touch signal, and the second control unit 342 generates a second control command signal corresponding to the color information of the touch signal.

The first control command signal and the second control command signal generated by the first control unit 341 and the second control unit 342 are included in one control command signal. As described above, the second control command signal is a control command signal that embodies the first control command signal and may be a command signal that embodies any one of speed, strength, and range of the first control command signal. That is, as described above, when a touch signal having a red triangular shape (△) is input, the first control command signal is configured to reproduce the operation, and the second control command signal specifies the speed of the first control command signal. Command the speed operation to the terminal. Therefore, when a control command signal including the first and second control command signals is output from the controller 340 to the terminal, the terminal performs the double speed reproduction operation.

Also, the gesture information may include trajectory information and thickness information of the touch signal, and thus, various first control command signals may be generated by various combinations of the trajectory information and the thickness information.

As such, through the touch recognition device according to the present invention, which receives the color information of the touch signal in advance through the touch palette unit 330 and generates various control command signals, various control command signals are transmitted to the terminal using only the touch signal. You can enter.

Hereinafter, a touch recognition method according to a third embodiment of the present invention will be described with reference to FIG. 4. 4 is a control flowchart illustrating a touch recognition method according to a third embodiment of the present invention.

The control flow diagram shown in FIG. 4 is a control flow chart that can be used in the touch recognition apparatus shown in FIG. 2A. Since the operation principle and the order are very similar, overlapping descriptions will be omitted and will be briefly described.

According to the touch recognition method according to the present embodiment, first, a touch signal is input to the touch recognition device by the user (S410). The touch signal may be input by the user to the touch recognition apparatus through the touch screen using the touch pen illustrated in FIG. 2B. In this case, the touch signal may be light having a specific wavelength value and may be light emitted from the light emitting diode included in the nib portion of the touch pen. This is based on the physical principle that the color information varies depending on the wavelength of light.

Next, gesture information of the input touch signal is detected (S420). According to the present exemplary embodiment, the detecting of the gesture information may include a step (S421) of detecting the track information of the touch signal and a step (S422) of detecting the thickness information of the touch signal.

In order to detect the information on the trajectory of the touch signal input by the user, the trajectory of the touch signal may be sensed through the coordinate value of the touch signal. In addition, when the touch signal is formed of a line, the thickness of the line is recognized. The thickness itself of the touch signal input to the touch screen may be recognized through coordinate values, but the thickness information is displayed together with color information from the beginning. It may be selected through a button of the touch pen.

After the gesture information of the touch signal is detected, the color information of the touch signal is detected (S430). In this case, the color information of the touch signal may be detected before the gesture information. The detection order of the color information and the gesture information of the touch signal is not limited by this drawing. Color information can be detected through the photo detector. The color information of the touch signal may be sensed by reading a wavelength value of light incident to the photo detector. A touch signal in the form of light having a specific wavelength value is input through the touch pen, and light having a specific wavelength value includes color information of the touch signal.

Next, a control command signal corresponding to the detected color information and gesture information is generated (S440). According to the present exemplary embodiment, the control signal generating step S440 is largely generated by generating a first control command signal corresponding to the gesture information (S441) and generating a second control command signal corresponding to the color information (S442). ) May be included.

A first control command signal is generated according to the gesture information in operation S441. For example, when the user inputs a touch signal having a red triangular shape (assuming that thickness information is not input separately), it detects that the touch signal has a triangular (Δ) trajectory (S420). . In operation S441, a first control command signal corresponding to the detected gesture information of the triangle (Δ) is generated, for example, a first control command signal for commanding a play operation.

Next, a second control command signal is generated according to the detected color information (S442). For example, as described above, when the user inputs a touch signal having a red triangle (△) shape (assuming that the thickness information is not input separately), the wavelength value of the touch signal is read and the input signal of the touch signal is read. The color information is detected to be red (S430). In operation S442, a second control command signal corresponding to the detected color information, that is, a red color, for example, a second control command signal for instructing operation at a double speed is generated (S442).

In this case, the first control command signal and the second control command signal are included in one control command signal. As described above, the second control command signal is a control command signal embodying the first control command signal and may be a command signal embodying any one of speed, intensity, and range of the first control command signal. . That is, as described above, when a touch signal having a red triangular shape (△) is input, the first control command signal is configured to reproduce the operation, and the second control command signal specifies the speed of the first control command signal. Command the speed operation to the terminal. Therefore, when the control command signal including the first and second control command signal is output from the control unit 240 to the terminal, the terminal performs the double speed playback operation.

As such, the second control command signal is a command signal embodying the first control command signal and may represent any one of speed, intensity, and range of the first control command signal. For example, when the first control command signal indicates a delete operation, the second control command signal commands the range of the check file, and includes a control including the first control command signal and the second control command signal. When the command signal is input to the terminal, the terminal deletes all of the check files. Therefore, more specific and various control command signals can be input to the terminal through the second control command signals generated corresponding to the color information.

In addition, as described above, the gesture information may include trajectory information and thickness information of the touch signal, and thus, various first control command signals may be generated by various combinations of the trajectory information and the thickness information.

As described above, by detecting the color information of the touch signal, various control command signals can be generated using only the touch signal through the touch recognition method according to the present invention, which can generate more various control command signals.

Hereinafter, a touch recognition method according to a fourth embodiment of the present invention will be described with reference to FIG. 5. 5 is a control flowchart illustrating a touch recognition method according to a fourth embodiment of the present invention.

The control flow chart shown in FIG. 5 is a control flow chart that can be used in the touch recognition apparatus shown in FIG. 3, and they are very similar in operation principle and sequence, and the control flow chart shown in FIG. Since it is also very similar, overlapping description will be omitted, and will be briefly described.

According to the touch recognition method according to the present embodiment, first, color information of a touch signal selected by a user is received (S510). The user may input color information through a touch palette including a plurality of color information menus as shown in FIG. 3, but the present invention is not limited thereto, and the user may input color information through various means within the scope of the present invention. It will be apparent to those skilled in the art. In this case, the color information may be RGB color information including red information, green information, and blue information.

Next, a touch signal having color information selected by the user is received (S520). In operation S530, gesture information of the input touch signal is detected. According to the present exemplary embodiment, the detecting of the gesture information may include a step (S531) of detecting the track information of the touch signal and a step (S532) of detecting the thickness information of the touch signal. The gesture information of the touch signal includes gesture information and thickness information of the touch signal.

Next, a control command signal corresponding to the detected color information and the gesture information is generated (S540). According to the present exemplary embodiment, the control signal generating step S540 may be largely performed by generating a first control command signal corresponding to the gesture information (S541) and generating a second control command signal corresponding to the color information (S542). ) May be included. In this case, the control command signal may include a first control command signal and a second control command signal.

A first control command signal based on the gesture information is generated (S541). For example, when a user inputs a touch signal having a red triangular shape (assuming that thickness information is not input separately), the first control command signal corresponding to the gesture information of the detected triangular shape (△) For example, a first control command signal for commanding a play operation is generated (S541).

In operation S542, a second control command signal is generated according to the color information selected by the user. For example, as described above, when a user inputs a touch signal having a red triangular (△) shape selected by the user (assuming that thickness information is not input separately), A second control command signal, for example, a second control command signal for commanding a double speed operation is generated (S542).

The second control command signal is a control command signal embodying the first control command signal and may be a command signal embodying any one of speed, strength, and range of the first control command signal. In addition, as described above, the gesture information may include trajectory information and thickness information of the touch signal, and thus, various first control command signals may be generated by various combinations of the trajectory information and the thickness information. According to the present exemplary embodiment, various control command signals may be recognized by sensing all of the thickness, trajectory, and color information of the touch signal through the above-described process.

Hereinafter, an example in which a touch signal is variously recognized by the touch recognition method and the touch recognition apparatus according to the present invention will be described with reference to FIG. 6. 6 is an exemplary diagram illustrating an example in which a touch signal is variously recognized in a touch recognition method and a touch recognition device according to an exemplary embodiment of the present invention.

Referring to the touch signals 611 and 612 having the same type of locus shown in FIG. 6, the touch signal 611 shown on the left side and the touch signal 612 shown on the right side have locus information of the same type. . However, the right touch signal 612 has a red color and the left touch signal 611 has black color information, so that control commands generated by the left and right touch signals are different from delete and delete. . That is, since the touch signal is recognized differently according to the color information, the control command signal generated according to the left touch signal 611 and the right touch signal 612 is different. In the same principle, the touch signal of 621 and the touch signal of 622 are the same type of touch signals or different colors, and thus generate different control command signals of reproduction and double speed reproduction, respectively. The 631 touch signal and the 6323 touch signal also generate different control commands such as' 3 seconds forward 'and '10 seconds forward' according to the color information. As described above, even the color information of the touch signal can be recognized, and various control command signals can be generated.

Hereinafter, the touch recognition method according to the present invention is used or the touch screen of the terminal including the touch recognition apparatus will be described with reference to FIG. 7. 7 is an exemplary diagram of a touch screen of a terminal using a touch recognition method according to the present invention or including a touch recognition device.
