Various embodiments are presented below for detailed description. However, the embodiments are only used as examples and do not limit the scope of the invention. In addition, some elements are omitted in the drawings in the embodiments to clearly show the technical features of the invention. The same reference numerals will be used to represent the same or similar elements in all drawings.

FIG1 is a schematic diagram of an optical article according to a first embodiment of the present invention. Referring to FIG1 , an embodiment of the present invention provides an optical article 10, which includes a plurality of foot pads 12 and a detection system 100. The detection system 100 is used to detect the degree of wear of the foot pads 12, and includes a light source module 110, a light source information generation module 120, a light source information judgment module 130, and a message generation module 140. Among them, the optical article 10 may be a mobile device, such as an optical mouse, but the present invention is not limited thereto. The foot pads 12 may be soft and sticky plastic sheets, and the number may be, for example, 4, but the present invention is not limited thereto. The optical article 10 may have a housing, and the detection system 100 is disposed in the housing.

Specifically, the light source module 110 of this embodiment can be a light emitting diode, a laser diode or other suitable light source modules. The light source module 110 is used to emit detection light L toward the placement surface S, wherein the optical article 10 is suitable for being placed on the placement surface S so that the foot pad 12 contacts the placement surface S.

In this embodiment, the light source information generating module 120 may be an image sensor. The light source information generation module 120 is used to receive the reflected light R reflected by the detection light L on the placement surface S, and generate the image quality IQ based on the reflected light R.

In this embodiment, the light source information judgment module 130 is electrically connected to the light source information generation module 120 and receives the image quality IQ. The message generation module 140 is electrically connected to the light source information judgment module 130 . When the difference between the image quality IQ value and the correction value is greater than the critical value, the light source information judgment module 130 sends the judgment result JR to the message generation module 140 . The message generation module 140 sends a signal (signal SI as shown in Figure 2, 3 or 4). After the signal is received, a reminder signal (reminder signal RS as shown in Figure 2 or 4) is generated to remind the replacement of the foot pad 12 of the optical article 10.

In this embodiment, the above-mentioned correction value corresponds to the original height of the foot pad 12, and the difference between the value of the image quality IQ and the correction value corresponds to the degree of wear of the foot pad 12 when the user uses the optical article 10. In other words, the value of the image quality IQ may correspond to the height of the foot pad when the optical article 10 is used, and the difference between the value of the image quality IQ and the correction value at this time corresponds to the degree of wear of the foot pad 12.

For example, the smoothness of movement of the optical article 10 on the placing surface S is related to the image quality IQ. The lower the image quality IQ value (image quality compliment), the smoother the movement of optical items. On the contrary, the higher the value of the image quality IQ, the worse the movement smoothness of the optical object 10 . Before the optical article 10 leaves the factory, a calibration is performed on the placement surface S (such as a common smooth plane) to obtain the pre-factory image quality IQ, and the value of the pre-factory image quality IQ is set as the correction value. The correction value reflects the original height of the foot pad 12 of the optical article 10, and the critical value of the optical article 10 can be set based on the correction value. Different optical articles 10 may have different correction values but may be set to have the same or different threshold values. The aforementioned correction value or threshold value is, for example, stored in the memory of the light source information judgment module 140 . When the optical article 10 is continuously used, the foot pads 12 are gradually worn, so that the distance between the light source module 110 and the placement surface S and the distance between the light source information generation module 120 and the placement surface S gradually become the original distance before leaving the factory. different. Therefore, the value of the image quality IQ generated by the light source information generation module 120 gradually becomes higher. When the difference between the image quality IQ value and the correction value is greater than the critical value, the user is reminded to replace the foot pad 12 . For example, the correction value is 127 and the threshold is set to 75. When the detection system 100 detects that the value of the image quality IQ is greater than 202, the user is reminded to replace the foot pad 12 .

In another embodiment, the light source information determination module 130 and the information generation module 140 can be integrated into an operation unit. The operation unit includes, for example, a microcontroller unit (MCU), a central processing unit (CPU), a microprocessor (microprocessor), a digital signal processor (DSP), a programmable controller, a programmable logic device (PLD) or other similar devices or a combination of these devices, and the present invention is not limited thereto. In addition, in one embodiment, each function of the operation unit can be implemented as a plurality of program codes. These program codes are stored in a memory and executed by the operation unit. Alternatively, in one embodiment, each function of the operation unit can be implemented as one or more circuits. The present invention does not limit the implementation of the functions of the computing unit by software or hardware.

FIG2 is a schematic diagram of the connection between the optical article and the host according to the first embodiment of the present invention. Please refer to FIG1 and FIG2 at the same time. In this embodiment, the above-mentioned reminder signal RS may include a sound signal, an image or a reminder message. The signal SI sent by the message generation module 140 is transmitted to the host 20 connected to the optical article 10 (wirelessly or wired) (that is, the host 20 receives the signal SI), so that the host 20 sends a sound signal (for example, a warning sound, voice or other sound signal), or the display 30 connected to the host 20 outputs an image or reminder message M. Among them, the host 20 can be a personal computer. In another embodiment, the host 20 can also be a tablet computer or a laptop computer including a display, but the present invention is not limited to this.

Based on the above, in one embodiment of the present invention, the detection system 100 of the optical article 10 uses the received reflected light R to generate the image quality IQ, and prompts for replacement when the difference between the image quality value and the correction value is greater than the critical value. Foot pads 12 of the optical article 10 . Therefore, the optical article 10 can maintain high sensitivity, provide a good user experience, and ensure a long service life of the optical article 10 .

In this embodiment, the indicator light 200 may be a light emitting diode or other suitable light source. The above reminder signal RS may include a light signal or a vibration signal. The indicator light 200 or the vibration module 300 is electrically connected to the message generation module 140 . The signal SI sent by the message generation module 140 is sent to the indicator light 200 or the vibration module 300 (that is, the indicator light 200 or the vibration module 300 receives the signal SI), causing the indicator light 200 to emit a light signal (for example, continuously flashing and lighting) or causing The vibration module 300 generates vibration signals. That is to say, the optical article 10' uses its own indicator light 200 or vibration module 300 to remind the replacement of the foot pad 12. However, in another embodiment, the message generation module 140 can also transmit the signal SI to the host (such as the host 20 shown in FIG. 2 ) at the same time, so that the host also sends the reminder signal RS. The remaining advantages of the optical article 10' of this embodiment are similar to the advantages of the optical article 10, and will not be described again here.

An embodiment of the present invention provides an optical system 1, which includes an optical article 10'', a light source information judgment module 130 and a message generation module 140. Among them, the optical article 10'' is similar to the optical article 10 of FIG. 1 or the optical article 10' of FIG. 3.

However, in another embodiment, the optical article 10'' may further include an indicator light 200 or a vibration module 300. The indicator light 200 or the vibration module 300 is signal-connected to the message generation module 140 (wirelessly or wired). The signal generating module 140 sends out a signal SI, which is then transmitted to the indicator light 200 or the vibration module 300, so that the indicator light 200 emits a light signal or the vibration module 300 emits or generates a vibration signal.

FIG. 5 is a flow chart of a method for detecting the wear degree of a foot pad of an optical article according to the first embodiment of the present invention. FIG. 6 is a flow chart for determining the wear degree of the foot pad of the optical article in FIG. 5 . In order to clearly explain the operation of each component in the aforementioned FIGS. 1 to 4 and the method of detecting the wear degree of the foot pad of an optical article according to the embodiment of the present invention, a detailed description will be given below with reference to the flowcharts in FIGS. 5 and 6 . However, those with ordinary knowledge in the technical field to which the present invention belongs can understand that the method for detecting the wear degree of the foot pad of an optical article according to the embodiment of the present invention is not limited to the optical article 10 and the optical article 10 shown in FIGS. 1 to 4 ' or the optical article 10 '' is not limited to the sequence of steps in the flow charts of Figures 5 and 6.

Please refer to Figures 5 and 6. An embodiment of the present invention provides a method for detecting the degree of wear of the foot pad 12 of the optical article 10, which includes the following steps. Step S300: Determine the degree of wear of the foot pad 12 of the optical article 10. Step S400: Receive the signal SI from the message generation module 140 and then generate a reminder signal RS to remind to replace the foot pad 12 of the optical article 10. In step S300, determining the degree of wear of the foot pad 12 of the optical article 10 includes the following steps S320, S340 and S360. Step S320: Use the light source module 110 to emit a detection light L toward the placement surface S. Step S340: Utilize the light source information generating module 120 to receive the reflected light R reflected by the placement surface S of the detection light L, and utilize the light source information generating module 120 to generate multiple image quality IQs at multiple different times. The generation of multiple image quality IQs at multiple different times is, for example, obtaining images of reflected light 10 times in sequence within 1 second, and generating 10 sets of image quality IQs. However, the present invention is not limited thereto, and the system can obtain multiple image quality IQs according to the sampling rate. Step S360: Utilize the light source information judging module 130 to receive the image quality IQ, and judge whether the difference between the average value of the image quality IQ (for example, the average value of 10 sets of image quality IQs obtained within 1 second) and the calibration value is greater than the critical value. When the difference between the average value of the image quality IQ value and the calibration value is greater than the critical value, it means that the wear degree of the pad 12 is abnormal, and the judgment result JR is transmitted to the message generation module 140, and the message generation module 140 then sends the signal SI (step S362). Then, the aforementioned step S400 is executed. In addition, step S300 is executed to determine the wear degree of the pad 12 of the optical article 10. When the difference between the average value of the image quality IQ value and the calibration value is less than or equal to the critical value, it means that the wear degree of the pad 12 is normal, and step S600 is executed to jump out of the process, and then execute other functions designed for the optical article 10.

In this embodiment, the above-mentioned method for detecting the wear of the foot pad 12 of the optical article 10 further includes the following steps. After the optical item 10 is powered on or wakes up from sleep (for example, the mouse is moved and wakes up from sleep) (step S100 ), it is determined whether the optical item 10 is moving (step S200 ). If yes (the optical article 10 is moving), the wear degree of the foot pad 12 of the optical article 10 is determined (step S300 ). If not (the optical object 10 has not moved), jump out of the process (step S600). The optical article 10 may be awakened from sleep, for example, by starting to be moved.

In addition, in this embodiment, the above-mentioned step of generating a reminder signal RS to remind the user to replace the foot pad 12 of the optical article 10 after receiving the signal SI from the message generating module 140 (step S400) includes the following steps. The signal SI from the message generating module 140 is transmitted to the indicator light 200 (i.e., the indicator light 200 receives the signal SI), so that the indicator light 200 emits a light signal. Alternatively, the signal SI from the message generating module 140 is transmitted to the vibration module 300 (i.e., the vibration module 300 receives the signal SI), so that the vibration module 300 generates a vibration signal. Alternatively, the signal SI from the message generating module 140 is transmitted to the host 20 connected to the optical article 10 (ie, the host 20 receives the signal SI), so that the host 20 emits a sound signal, or the display 30 connected to the host 20 outputs an image or a reminder message M.

FIG7 is a flow chart for determining whether the optical article in FIG5 is moving. Referring to FIG5 and FIG7, in one embodiment, the above step S200 may include step S220 and step S240. Step S220: Use the light source information generation module 120 to generate a position movement signal to determine whether the optical article 10 is moving. If yes, proceed to step S300 (shown in FIG5). If no, determine whether it exceeds a specific time (step S240). If it exceeds the specific time (the determination result of step S240 is yes), execute step S600 and exit the process. If it does not exceed the specific time (the determination result of step S240 is no), execute step S220 again. For example, after the light source information generating module 120 receives the reflected light R reflected by the detection light L from the placement surface S, it can obtain the light spot diagram of the detection light L irradiated on the placement surface S. If the light spot diagram changes with time, the system can determine that the optical article 10 is in a moving state, and the system can further generate a position movement signal. On the contrary, if the light spot diagram does not change with time, the system can determine that the optical article 10 is not in a moving state. The system continues to execute step S220 within a specific time. The specific time is, for example, 3 seconds. If it exceeds the specific time, the process is jumped out (step S600).

FIG8 is a flow chart of a method for detecting the degree of wear of the foot pad of an optical article according to the second embodiment of the present invention, wherein steps S100, S200, S300, S362, S400 and S600 of FIG8 are the same or similar to steps S100, S200, S300, S362, S400 and S600 of FIG5 , and thus will not be repeated. The method for detecting the degree of wear of the foot pad of an optical article of this embodiment is similar to the method of FIG5 , and the main differences are as follows. The method for detecting the degree of wear of the foot pad of an optical article further includes step S700: determining whether the value of the image quality IQ is within a specific range. If yes, proceed to step S200. If not, then the process is exited (step S600). In one embodiment, step S700 may include steps S320 and S340 in step S300. That is, in step S700, the light source module 110 is used to emit detection light L. Then, the light source information generation module 120 is used to receive the reflected light R, and the light source information generation module 120 is used to generate the image quality IQ, and then it is determined whether the value of the image quality IQ is within a specific range. In another embodiment, after the light source module 110 emits the detection light L, the light source information generation module 120 does not receive the reflected light R. In this case, the image quality IQ value will be much greater than the critical value. For example, the value range of the image quality IQ falls between 0 and 255, but the value of the image quality IQ will not appear near the minimum or maximum value of 0 or 255 in normal use of the optical article 10. When the value of the image quality IQ appears near the minimum or maximum value of 0 or 255, the optical article 10 may not be used on the normal surface, or the optical article 10 may be reversed. Among them, the specific range is set to 10 to 245, for example, but the present invention is not limited thereto. Therefore, setting step S700 helps to exclude the situation that the optical article 10 is not in normal use, and avoids entering step S300 to cause the system to misjudge and generate the reminder signal RS.

FIG. 9 is a flow chart of a method for detecting the wear degree of a foot pad of an optical article according to a third embodiment of the present invention. The method of detecting the wear degree of the foot pad of an optical article according to the embodiment of the present invention is not limited to the optical article 10, the optical article 10' or the optical article 10'' and the host 20 or the host 20" in Figures 1 to 4. In In this embodiment, the user can actively detect the degree of wear of the foot pads of the optical article. The method of detecting the degree of wear of the foot pads of the optical article in this embodiment is similar to the method in Figure 5, with the main differences being as follows. Detection The method for measuring the wear degree of the foot pads of optical items also includes steps S100' and S800. Step S100': The host 20 sends a detection command. In this embodiment, the user can operate, for example, the host 20 of Figure 2 (or the host of Figure 4 Host 20"), transmits the detection command to the optical article 10 of Figure 1 (or the optical article 10' of Figure 3, the optical article 10" of Figure 4) through the host 20. Then step S800 is executed: the host 20 determines whether the optical article 10 is in Sleep or power saving mode. If yes, after the optical item 10 receives the detection command, the optical item 10 starts to execute step S200 of determining the wear degree of the foot pad 12 of the optical item 10. If yes, executes step S600. For example That is, the host 20 sends a detection command to the optical item 10. When no confirmation message is received from the optical item 10 within a preset time, the host 20 determines that the optical item 10 is in sleep or power saving mode. In this embodiment , after the host 20 sends the detection command (step S100') and determines whether the optical article 10 is in the sleep or power saving mode (step S800), it executes steps S200 to step S600. Steps S200, S300, S362, S400 and S600 of Figure 9 The same or similar steps S200, S300, S362, S400 and S600 in Figure 5 will not be described again. That is to say, the host 20 sends a detection command, and the optical article 10 receives the detection command and then returns the value of the image quality IQ. Let the host 20 determine and process. In addition, the method for detecting the wear degree of the foot pad of an optical article in this embodiment may also include step S700 in FIG. 8 , and step S700 may be executed after step S800 and before step S200.

To sum up, in an embodiment of the present invention, a detection system for an optical article or a method for detecting the wear degree of a plurality of pads of an optical article uses the received reflected light to generate image quality, and the image quality is improved When the value or the difference between the average value and the correction value is greater than the critical value, the user is reminded to replace the foot pad of the optical item. Therefore, optical items can maintain high sensitivity, provide a good user experience, and have a longer service life.
