DETAILED DESCRIPTION
[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of an embodiment of the scanning pen provided in this application; Figure 2 for Figure 1 A perspective cutaway view of the scanning pen shown.
[0025] In this embodiment, the scanning pen 100 includes a pen body shell 110 and three screens. The pen body shell 110 includes three shell walls 111. The three shell walls 111 enclose a shell body with a triangular cross-section. A screen is installed on each shell wall 111, and the screen is used to display scanning information representing the scanned object.
[0026] The cross-section of the pen body of the scanning pen 100 is triangular, and screens for displaying scanning information are installed on the three shell walls 111 of the pen body shell 110. Compared with the existing flat structure scanning pens, such a pen body structure is more convenient for users to hold. At the same time, because three screens are provided according to the shape of the pen body shell, no matter what the holding direction is, after scanning the scanning object, there is no need to adjust the holding direction of the scanning pen, and the scanning information representing the scanning object can be intuitively viewed through one of the screens.
[0027] In the application, the scanning pen 100 can process the scanned object, and the scanning pen 100 can control the screen to directly display the scanned object, or display content related to the scanned object. For example, when the scanned object is in a foreign language, the scanned object can be translated, and the translated content can also be displayed on the screen. In short, the aforementioned scanning information can be the scanned object, or content related to the scanned object.
[0028] In a specific implementation, in order to facilitate the user to hold and view the content displayed on any screen, the cross-section of the pen body shell 110 can be set to an equilateral triangle structure, or a structure similar to an equilateral triangle.
[0029] In one implementation, the scanning pen 100 may further include a pen head shell 120, which is connected to the pen body shell 110. In the pen length direction, the cross-sectional size of the pen head shell 120 gradually decreases from the pen body shell 110 to the pen head shell 120. In application, the pen head shell 120 is the scanning end of the scanning pen 100. In this way, the appearance of the scanning pen 100 is closer to the structure of a conventional pen, which is conducive to improving the convenience of use for users.
[0030] In a specific implementation, the front end of the pen head shell 120 away from the pen body shell 110 is a conical structure, and the front end thereof has a plug hole, and the scanning pen 100 may include a refill 140 that can be plugged into the plug hole. The refill 140 is replaceable, and the refill 140 can communicate with the control circuit in the scanning pen 100, so that the scanning pen 100 has the function of a capacitive pen, and can be applied to electronic devices such as smart phones and tablets to realize functions such as gesture control, drawing editing or text input, so as to expand the application scope of the scanning pen 100.
[0031] Of course, in other implementations, the pen core 140 may simply serve as a structure that facilitates the user to determine the scanning range, which can simplify the control circuit and other related settings of the scanning pen 100.
[0032] Please refer to Figure 3 , Figure 3 It is a hardware system block diagram of the scanning pen in a specific embodiment.
[0033] In this embodiment, the scanning pen 100 further includes an electric control board 160 and a detection module 170, wherein the electric control board 160 and the detection module 170 are both disposed inside the pen body shell 110. It can be understood that the three shell walls 111 of the pen body shell 110 enclose a cavity, and the electric control board 160 and the detection module 170 can be placed in the cavity.
[0034] The detection module 170 is electrically connected to the electric control board 160 , and the detection module 170 is used to detect the position information of the electric control board 160 , and the electric control board 160 is used to control one of the three screens to light up according to the position information detected by the detection module 170 .
[0035] In a specific application, after the electric control board 160 is installed in the inner cavity of the pen body shell 110 , the relative positions of the electric control board 160 and the pen body shell 110 are fixed, that is, the position of the electric control board 160 in the pen body shell 110 remains unchanged.
[0036] When the user uses the scanning pen 100, the screen that the user can intuitively see is different according to the different holding directions. That is, the screen that the user can see changes according to the change of the holding direction without changing the direction of the scanning pen 100.
[0037] Although the relative position between the electric control board 160 and the pen body shell 110 remains unchanged, the relative position between the electric control board 160 and the external reference datum is changed. For example, the relative position between the electric control board 160 and the plane where the scanning object is located changes with the different holding directions of the scanning pen 100 by the user. Therefore, the position information of the electric control board 160 can be detected according to the detection module 170 to determine which screen the user can intuitively see in the current holding state, so as to control the screen to light up through the electric control board 160, so that the user can intuitively see the scanning information displayed on the screen that is lit up.
[0038] In a specific implementation, the position information of the electric control board 160 includes the angle between the electric control board 160 and a set reference datum. Obviously, the set reference datum is not related to the structure of the scanning pen 100 itself, or in other words, the set reference datum is not a fixed structure of the scanning pen 100.
[0039] Exemplarily, the aforementioned reference datum may be a plane where the scan object is located. The reference plane may also be a horizontal plane or a vertical plane.
[0040] Combine the following Figure 4 To illustrate the relationship between the position information of the electric control board 160 and the screen that is lit in a specific application. For the convenience of explanation, the three screens of the scanning pen 100 are respectively referred to as the first screen 131, the second screen 132 and the third screen 133.
[0041] Figure 4 (a) to Figure 4 In (c), the relative position relationship between the cross section of the scanning pen 100 and the set reference datum S is used to illustrate a corresponding relationship between the holding direction of the scanning pen 100 and the bright screen.
[0042] exist Figure 4 In the example shown, the electronic control board 160 of the scanning pen 110 is arranged vertically to the second screen 132 .
[0043] like Figure 4 As shown in (a), during use, the detection module 170 of the scanning pen 100 detects that the angle between the electronic control board 160 and the set reference base S is α1. When α1 is specifically 90 degrees, the electronic control board 160 can control the first screen 131 to light up to display the scanning information.
[0044] like Figure 4 As shown in (b), during use, the detection module 170 of the scanning pen 100 detects that the angle between the electric control board 160 and the set reference base S is α2. When α2 is 150 degrees, the electric control board 160 can control the second screen 132 to light up to display the scanning information.
[0045] like Figure 4As shown in (c), during use, the detection module 170 of the scanning pen 100 detects that the angle between the electronic control board 160 and the set reference base S is α3. When α3 is 30 degrees, the electronic control board 160 can control the third screen 132 to light up to display the scanning information.
[0046] Figure 4 In the example, the user can directly see the left screen of the scanning pen 100 in the figure. Figure 4 In (a), the first screen 131 faces the left side, and the second screen 132 is parallel to the set reference datum S. Figure 4 (b), the scanning pen 100 is relatively Figure 4 (a) The scanning pen 100 shown is rotated clockwise at a certain angle, so that the second screen 132 faces the left side and the third screen 133 is parallel to the set reference datum S. Figure 4 (c), the scanning pen 100 is relatively Figure 4 (b) The scanning pen 100 shown is rotated clockwise by a certain angle, so that the third screen 133 faces the left side and the first screen 131 is parallel to the set reference datum S.
[0047] In the above example, the detection module 170 uses the angle between the electric control board 160 and the set reference base S as a condition to trigger the corresponding screen to light up. In actual applications, different users hold the scanning pen 100 in different postures, and it is impossible to hold it in the same position accurately. To ensure that the electric control board 160 can control the screen to light up, the condition for each screen to light up can be an angle range. Figure 4 For example, in Figure 4 In the state shown in (a), the detection module 170 can be set to detect that the angle α1 between the electric control board 160 and the set reference base S is between 85 and 95 degrees, and the first screen 131 is driven to light up, and other similar settings are provided. It can be understood that the aforementioned angle values or angle ranges are exemplary descriptions. In actual applications, the conditions for triggering each screen to light up can be determined based on the installation position of the electric control board 160 on the scanning pen 100 and actual application tests.
[0048] Exemplarily, the detection module 170 may use a sensor capable of measuring orientation, such as a gyroscope.
[0049] In this embodiment, the scanning pen 100 may also include a human body sensing module 180. A human body sensing module 180 is set at each screen. The electronic control board 160 is electrically connected to the human body sensing module 180. The electronic control board 160 is used to control the corresponding screen to turn on or off according to the sensing signal transmitted by the human body sensing module 180.
[0050] Exemplarily, the human body sensing module 180 may use a 1D-TOF sensor.
[0051] In some application scenarios, there are scenarios where two users share the scanning pen 100. For example, one user holds the scanning pen 100 to scan, and after scanning, he can choose to display the scanning information to another user for viewing. At this time, the user holding the scanning pen 100 can turn the other screen toward the other user without changing the holding direction of the scanning pen 100. Through the detection of the human body sensing module 180, the electronic control board 160 can control the screen facing the other user to light up to display the scanning information.
[0052] For example, if the human body sensing module 180 provided at the first screen 131 senses that there is a user in front of the first screen 131, the electric control board 160 can control the first screen 131 to light up according to the sensing signal transmitted by the human body sensing module 180 indicating that there is a user in front of the first screen 131, so as to display the scan information. If the human body sensing module 180 provided at the first screen 131 does not sense that there is a user in front of the first screen 131, the electric control board 160 can control the first screen 131 to turn off according to the sensing signal transmitted by the human body sensing module 180 indicating that there is no user in front of the first screen 131.
[0053] In a specific application, the electric control board 160 can also be used to control at least two screens in the bright screen state to display the same content or different content. In other words, the electric control board 160 can control two or three bright screens to be in the same display state or different display state.
[0054] For example, when the scanned object is in a foreign language, the content of the scanned object can be directly displayed on one bright screen, and the translation content corresponding to the scanned object can be displayed on another bright screen to meet the different needs of users.
[0055] The electric control board 160 can control the two bright screens to be in the same display state or different display state according to the received control instruction.
[0056] Taking the bright screen display of the first screen 131 and the second screen 132 as an example, when the electronic control board 160 receives the control instruction of the dual-screen simultaneous display, the electronic control board 160 can output the display information after processing the scanned object to the first screen 131 and the second screen 132 at the same time, so that the first screen 131 and the second screen 132 display the same information; when the electronic control board 160 receives the control instruction of the dual-screen different display, the electronic control board 160 can process the scanned object to obtain the first display information and the second display information. For example, the first display information can be the content of the scanned object itself, and the second display information can be the extended content related to the scanned object. The electronic control board 160 can control the first display information to be output to the first screen 131, and the second display information to be output to the second screen 132, so that the first screen 131 and the second screen 132 display different contents. Of course, the electronic control board 160 can also control the first display information to be output to the second screen 132, and the second display information to be output to the first screen 131.
[0057] In a specific application, the electronic control board 160 of the scanning pen 100 can switch between a dual-screen same display mode and a dual-screen different display mode.
[0058] In one implementation, the electronic control board 160 of the scanning pen 100 may be provided with a storage module and a processing module, and the storage module may store a control program that can be run on the processing module to achieve switching between different modes of dual-screen display. For example, the electronic control board 160 may be an Android motherboard. Figure 5 The principle of switching the dual-screen display modes of the scanning pen 100 is described.
[0059] For the convenience of description and understanding, the first screen 131 and the second screen 132 of the scanning pen 100 are displayed on the screen at the same time as an example.
[0060] The electric control board 160 can maintain the current window stack through a list of window objects (windowstate), and the list represents the windows displayed by the current window from the beginning to the end, and the front and back layout order, and the list is bound to the current display screen, such as the first screen 131. In short, the content displayed on the first screen 131 is the windows arranged in sequence in the current window stack, that is, the windows in the current window stack are part of the content that needs to be displayed on the display screen bound to the current window stack.
[0061] After receiving the mode switching control instruction, the electric control board 160 first determines the current display mode of the first screen 131 and the second screen 132. If the current display contents of the first screen 131 and the second screen 132 are the same, that is, the current dual-screen same display mode, then a new window stack, namely the second window stack, is created according to the default window stack list, and the second screen 132 operation context object is obtained through the display manager service (Displaymanager service), and the newly created second window stack is bound to the obtained context object. The current window object (windowstate) is searched from the default window stack, and after obtaining it, it is added to the second window stack, and the window object is removed from the default window stack; if the current display contents of the first screen 131 and the second screen 132 are different, that is, the current dual-screen different display mode is searched for the default window stack to obtain the window object of the current application, the application window in the second window stack is moved to the top of the default window stack, and then the window object of the current application is moved to the second window stack.
[0062] In one implementation, the pen housing 120 may have three windows 123, which correspond to three screens respectively. The scanning pen 100 includes a camera module 190, which can shoot the scanned object through each window 123. Specifically, the camera module 190 may be provided with a camera unit at a position corresponding to each window 123.
[0063] In another implementation, the pen head shell 120 may have only one window 123, and the pen head shell 120 can rotate relative to the pen body shell 110 to change the position of the window 123. The scanning pen 100 is provided with a camera module 190, and the camera module 190 can photograph the scanned object through the window 123. In application, the pen head shell 120 is rotated according to the user's holding posture to ensure that the camera module 190 can photograph the scanned object through the window 123 in the holding posture.
[0064] In this embodiment, the scanning pen 100 can also be provided with a button 150, and the button 150 can be provided close to the pen head shell 120. Control instructions can be sent to the electronic control board 160 by pressing the button 150 or sliding the button 150. These control instructions may include instructions for triggering scanning, or instructions for switching the dual-screen display status, etc.
[0065] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
