Please refer to FIG. 1 , which is a schematic diagram of the indicator input device of the present invention. The pointer input device 100 of this embodiment can be a mouse, and the user can operate an electronic device 180 by operating the pointer input device 100 to generate a corresponding pointer input signal. The electronic device 180 includes, for example, a desktop computer, a notebook computer, and the like.

The index input device 100 includes a camera unit 110 , a first control unit 120 , a sensing unit 130 , a second control unit 140 , an enabling unit 150 and a signal transmission unit 160 . The camera unit 110 is used for generating image signals. Wherein, the photographing unit 110 is, for example, a Charge Coupled Device (CCD) photographing lens or a Complementary Metal-Oxide-Semiconductor (CMOS) photographing lens, for capturing an image to generate an image signal. Further, the camera unit 110 may include an image lens and an image sensor. That is, the image is formed, for example, by an image lens, and the imaged image is converted into an image signal by an image sensor to generate an image signal. In addition, the camera unit 110 can further scan a two-dimensional barcode, such as a QR code, and convert the two-dimensional barcode into an image signal for output.

The first control unit 120 is coupled to the camera unit 110 for receiving an image signal and outputting the image signal according to the enable signal. For example, when the enable signal is at a high logic level, the first control unit 120 outputs the received image signal. When the enabling signal is at a low logic level, the first control unit 120 will not output the received image signal.

The sensing unit 130 is used for sensing the displacement operation of the indicator input device 100 to generate a displacement operation signal. Further, the sensing unit 130, for example, senses the relative displacement between the indicator input device 100 and the desktop 210 (as shown in FIG. 2A and FIG. 2B ), provides corresponding path coordinate data, and converts the path coordinate data into Shift operation signal and output.

The second control unit 140 is coupled to the sensing unit 130 for receiving the displacement operation signal and outputting the displacement operation signal according to the enabling signal. For example, when the enable signal is at a high logic level (potential), the second control unit 140 will not output the received shift operation signal. When the enable signal is at a low logic level, the second control unit 140 outputs the received shift operation signal.

The enabling unit 150 is coupled to the first control unit 120 and the second control unit 140 for generating an enabling signal according to the lifting operation of the index input device 100 . For example, when the indicator input device 100 is not lifted, that is, the indicator input device 100 is placed on the desktop 210, the enabling unit 150 is not enabled, and the enabling unit 150 generates, for example, a low logic level accordingly. The enable signal of the pointer input device 100 is in a pointer input mode (such as a mouse mode), as shown in FIG. 2A .

When the indicator input device 100 is lifted, that is, the indicator input device 100 is not placed on the desktop 210, the enabling unit 150 is enabled, and the enabling unit 150 generates an enabling signal such as a high logic level accordingly, Make the indicator input device 100 be in an image capture mode (such as photography or photographing mode), as shown in FIG. 2B . In this embodiment, the enabling unit 150 is, for example, a ball switch, but the present invention is not limited thereto, and the enabling unit 150 can also be other similar elements to generate the enabling signal.

The signal transmission unit 160 is coupled to the first control unit 120 and the second control unit 140, and is used to receive an image signal or an index input signal, so as to transmit the image signal or a displacement operation signal to the electronic device 180, so that the electronic device 180 Or displacement operation signal, and perform subsequent related processing. In this embodiment, the signal transmission unit 160 is, for example, a universal serial bus hub (UniversalSeries Bus Hub, USB Hub), and the signal transmission unit 160 transmits the image signal or the displacement operation signal to the electronic device 180, for example, in a wired or wireless manner. . In this way, the indicator input device 100 can have both the functions of indicator input and image capture, so as to increase the convenience of use.

In addition, the index input device 100 of this embodiment further includes a trigger unit 170 . The trigger unit 170 is coupled to the first control unit 120 and the second control unit 140 for generating a trigger signal. Wherein, the trigger unit 170 is, for example, a button or a scroll wheel, and the user can operate the trigger unit 170 by pressing a button, or sliding or pressing a scroll wheel, so that the trigger unit 170 generates a corresponding trigger signal.

Moreover, the aforementioned trigger signal will be transmitted to the first control unit 120 and the second control unit 140 . In this embodiment, the first control unit 120 can further output the image signal according to the trigger signal generated by the trigger unit 170 and the enable signal generated by the enable unit 150 . For example, when the enable signal is at a high logic level and the trigger unit 170 generates a trigger signal, the first control unit 120 outputs an image signal. When the enable signal is at a low logic level and the trigger unit 170 generates a trigger signal, the first control unit 120 will not output an image signal. That is to say, when the pointer input device 100 is in the image capturing mode (such as shooting or photographing mode), the user can perform image capturing (photography or photographing) by operating the trigger unit 170, and then through the first control unit The 120 processing and signal transmitting unit 160 transmits the image signal to the electronic device 180, so that the electronic device 180 performs subsequent processing and operation accordingly.

On the other hand, when the enable signal is at a high logic level and the trigger unit 170 generates the trigger signal, the second control unit 140 will not output the trigger signal. When the enable signal is at a low logic level and the trigger unit 170 generates a trigger signal, the first control unit 120 outputs the trigger signal. That is to say, when the pointer input device 100 is in the pointer input mode (such as the mouse mode), the user can generate a corresponding trigger signal by operating the trigger unit 170, and then process it through the first control unit 120 and send it to the signal transmission unit 160. , so as to send the trigger signal to the electronic device 180, so that the electronic device 180 performs subsequent processing and operations according to the trigger signal.

In this embodiment, one trigger unit 170 is taken as an example, but the present invention is not limited thereto, and the trigger unit 170 may also be two or more than two. For example, when there are two trigger units 170, the trigger units 170 are, for example, two buttons, or one button and one scroll wheel. When there are three trigger units 170, the trigger units 170 are, for example, two buttons and one scroll wheel.

In the foregoing embodiments, the enabling unit 150 is exemplified by a ball switch to generate the enabling signal, but the present invention is not limited thereto. Another example will be given below to illustrate.

Please refer to FIG. 2C and FIG. 2D , which are respectively another schematic diagram of operation and another schematic diagram of operation of the indicator input device of the present invention. Wherein, the sensing unit 130 can, for example, emit a light 221 and generate a corresponding displacement operation signal according to whether the refracted light 222 corresponding to the light 221 refracted by the desktop 210 is received or not.

For example, when the indicator input device 100 is placed on the desktop 210 (as shown in FIG. 2C ), the light 221 emitted by the sensing unit 130 can be refracted by the desktop 210 to generate a refracted light 222 , and the sensing unit 130 receives After the light 222 is refracted, a displacement operation signal can be generated accordingly, and the displacement operation signal will be sent to the second control unit 140 .

When the indicator input device 100 is not placed on the desktop 210 (as shown in FIG. 2D ), the light 221 emitted by the sensing unit 130 will not be refracted by the desktop 210, and the sensing unit 130 will not receive the refracted light and Shift operation signals are not generated.

Next, in one embodiment, the enabling unit 150 can further read the displacement operation signal received by the second control unit 140, and compare the generation time of the displacement operation signal with the preset time, so as to serve as a judgment index input device 100 based on the lifting operation, so as to generate the enabling signal. Wherein, the aforementioned preset time is, for example, 1 second (S).

For example, when the enabling unit 150 compares that the aforementioned generation time is greater than the preset time, it means that the sensing unit 130 has received the refracted light 222 refracted by the desktop 210, and the enabling unit 150 will determine that the indicator input device If the lifting operation of 100 is not lifted, the enabling unit 150 will generate an enabling signal such as a low logic level, so that the pointing input device 100 is in a pointing input mode (such as a mouse mode).

In addition, when the enabling unit 150 compares that the aforementioned generation time is less than the preset time, it means that the sensing unit 130 has not received the refracted light 222 refracted by the desktop 210 , and the enabling unit 150 will determine that the index input device 100 is When the lifting operation is lifted, the enabling unit 150 will generate an enabling signal such as a high logic level, so that the indicator input device 100 is in an image capturing mode (such as a photographing or photographing mode).

In another embodiment, the enabling unit 150 can further read the displacement operation signal received by the second control unit 140, and compare the surface characteristic value of the displacement operation signal with a preset value as a judgment index input device 100 based on the lifting operation, so as to generate the enabling signal. Wherein, the surface characteristic value is, for example, an image result captured by the sensing unit 130 .

That is to say, when the indicator input device 100 is placed on the desktop 210 , the surface characteristic value of the displacement operation signal generated by the sensing unit 130 is larger, that is, the image quality is better. When the indicator input device 100 is farther away from the desktop 210 , the surface characteristic value of the displacement operation signal generated by the sensing unit 130 is smaller, that is, the image quality is poorer. The surface feature value is, for example, between 0 and 255, wherein "255" indicates that the sensing unit 130 of the indicator input device 100 has completely received the reflected light 222 (as shown in FIG. 2C ), and "0" indicates that the sensor of the indicator input device 100 The measuring unit 130 does not receive the reflected light (as shown in FIG. 2D ). Wherein, the aforementioned preset value is, for example, 240, but it is not limited thereto, and users can adjust it according to their needs.

For example, when the surface feature value of the displacement operation signal obtained by the enabling unit 150 is greater than the preset value, it means that the quality of the image captured by the sensing unit 130 is better, and the enabling unit 150 will determine that the pointer input device The lifting operation of 100 is not lifted (that is, the indicator input device 100 is placed on the desktop 210), then the enabling unit 150 will generate, for example, an enabling signal of a low logic level, so that the indicator input device 100 is in an indicator input mode (for example, mouse mode).

In addition, when the surface characteristic value of the displacement operation signal compared by the enabling unit 150 is less than the preset time, the quality of the image captured by the sensing unit 130 is poor, and the enabling unit 150 will determine that the pointer input device 100 is lifted. When the operation is lifted, the enabling unit 150 will generate an enabling signal such as a high logic level, so that the pointer input device 100 is in an image capture mode (such as a photographing or photographing mode).

Please refer to FIG. 3A and FIG. 3B , which are respectively a perspective view and another perspective view of the indicator input device of the present invention. The index input device 100 has a casing 310 , and the casing 310 has a first surface 311 and a second surface 312 opposite to the first surface 311 . Wherein, the trigger unit 170 is, for example, disposed on the first surface 311 of the casing. In this embodiment, the number of trigger units 170 is 3 as an example, and they are 2 buttons and 1 scroll wheel respectively, but this embodiment is not limited thereto, and the number of trigger units 170 can also be 1, 2 or More than 3, can be configured by the user according to the needs.

The photographing unit 110 and the sensing unit 130 are respectively disposed on the second surface 312 of the casing 310 , and the photographing unit 110 is disposed adjacent to the sensing unit 130 . However, the illustrated positions of the photographing unit 110 and the sensing unit 130 are only an implementation manner of this embodiment, and users can also adjust the positions of the photographing unit 110 and the sensing unit 130 according to their needs. The first control unit 120 , the second control unit 140 , the enabling unit 150 and the signal transmission unit 160 are, for example, disposed in the casing 310 .

The indicator input device 100 proposed by the embodiment of the present utility model generates an enabling signal through the enabling unit 150 to switch the image signal generated by the imaging unit 110 output by the first control unit 120, or to switch the image signal generated by the second control unit 120. The control unit 140 outputs the displacement operation signal generated by the sensing unit 130 , and transmits the image signal or the displacement operation signal to the electronic device 180 through the signal transmission unit 160 for subsequent processing and operation. In addition, the trigger unit 170 can also be used to generate a trigger signal, so that when the pointer input device 100 is in the image capture mode, the first control unit 120 controls the camera unit 110 to take pictures, or the pointer input device 100 is in the pointer In the input mode, the second control unit 140 is caused to output a trigger signal, and then the image signal or the trigger signal is transmitted to the electronic device through the signal transmission unit 160 for subsequent processing and operation.
