Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of electronic whiteboard control, and in particular relates to a multifunctional remote-controlled electronic whiteboard system. Background Art
[0002] There are two types of remote controllers for electronic whiteboards on the market: one is a large remote controller with more than 50 buttons and a full range of function keys, but the panel is relatively large and not easy to carry; the other is a small remote controller with only more than 10 buttons, which only covers common functions such as power on / off, confirmation and cancellation, but the panel is relatively small, which is convenient to operate and carry. Most customers prefer small remote controllers, and electronic whiteboards shipped from the factory are generally equipped with small remote controllers, which are more in line with market demand.
[0003] According to customer feedback, different customers have slightly different requirements for key values or commonly used function keys on small remote controllers: for example, some people need to turn off the screen with one button, while others need screenshot function, screen lock function, etc. However, due to the limited number of buttons, the standard small remote controller is generally only equipped with the most commonly used function keys, and the functional requirements of customers are rich and varied and vary from person to person, making it difficult to achieve standardization of remote controllers, especially difficult to meet the diverse needs of users. Summary of the invention
[0004] The main purpose of the present invention is to provide a multi-functional remote control electronic whiteboard system to solve the problems existing in the prior art, and to adapt the multi-functional key values to realize the remote control of the electronic whiteboard, so that the standardization of the remote control is easier to achieve to meet the diverse needs of users.
[0005] In order to achieve the above object, the solution of the present invention is: A multifunctional remote-controlled electronic whiteboard system comprises an electronic whiteboard and a remote controller, wherein the electronic whiteboard comprises a display, a control unit, a setting unit and a receiving unit, and the remote controller comprises an operating unit and a transmitting unit; the display is configured to display a user interface of the electronic whiteboard; the control unit comprises a plurality of function modules, each function module uniquely corresponding to a control event; the operating unit comprises a plurality of physical function keys, each function key is configured to have at least one key value; the setting unit is configured to modify the mapping relationship between the key value and the function module, so that each function module has a mapping relationship with at most one key value; the receiving unit is communicatively connected with the transmitting unit, and when a user presses a function key, the key value corresponding to the operation is sent by the transmitting unit to the receiving unit and forwarded to the control unit, and the control unit calls the function module mapped with the key value and makes the user interface respond to the control event corresponding to the function module.
[0006] The default functions of the function keys of the remote control when leaving the factory are consistent with the functions corresponding to the patterns silk-screened on the button surfaces.
[0007] The setting unit is configured to call the corresponding virtual remote control UI and display it on the top level of the user interface when the user selects the "key mapping setting" function in the user interface of the display. After that, the user performs a certain operation on a function key and selects the function module to be mapped. The setting unit records the key value corresponding to the operation and maps it to the function module selected by the user; the mapped function key is highlighted at the corresponding position of the virtual remote control UI, and the corresponding function description is displayed.
[0008] Preferably, the electronic whiteboard also includes a prompt unit; the prompt unit is configured to reset the system's "first operation after change" flag, and when the user modifies the mapping relationship between the key value and the function module through the setting unit, the prompt unit resets the flag to 0; after the receiving unit receives the key value sent by the transmitting unit, it first forwards it to the prompt unit, and after receiving the key value, the prompt unit checks the "first operation after change" flag: if the flag is 1, the key value is directly forwarded to the control unit; if the flag is 0, the virtual remote control UI is called to display it at the top level of the user interface, and all function keys of the edited functions are highlighted at the corresponding position of the virtual remote control UI and the function description corresponding to each function key is displayed, and then the flag is modified to 1, and the corresponding key value is not forwarded to the control unit.
[0009] Preferably, when the virtual remote control UI is called by the setting unit, it disappears after the user completes the setting and clicks to confirm; when the virtual remote control UI is called by the prompt unit, it disappears after displaying a preset time or the user operates the remote control again.
[0010] The function key has four key values corresponding to the operations of short press, long press, double press, and continuous press.
[0011] After adopting the above technical solution, the present invention has the following technical effects: After the present invention matches the remote control with the electronic whiteboard, the mapping relationship between the function keys of the remote control and the function modules built into the electronic whiteboard system can be freely adjusted in the system setting interface. Specifically, each function key has at least one key value, and the key value can be uniquely mapped to the function module according to user needs, so that when the user performs a specific operation on a certain function key, the electronic whiteboard can respond and execute the corresponding event, thereby realizing the customization of the function keys of the remote control, and the user can flexibly set them according to their own needs to meet diverse user needs; for manufacturers, only the system software needs to be modified to produce standardized remote controls without increasing physical costs; the communication and control relationship of the present invention is easy to implement at the code level without creative labor.

DETAILED DESCRIPTION
[0013] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.
[0014] refer to Figure 1-3 As shown, the present invention discloses a multifunctional remote-controlled electronic whiteboard system, including an electronic whiteboard 1 and a remote controller 2, wherein the electronic whiteboard 1 includes a display 11, a control unit 12, a setting unit 13 and a receiving unit 14, and the remote controller 2 includes an operating unit 21 and a transmitting unit 22; The display 11 is configured to display the user interface of the electronic whiteboard 1; The control unit 12 includes a plurality of function modules 121, each function module 121 uniquely corresponds to a control event, such as one-key shutdown, one-key restart, screenshot, screen lock, etc.; the operation unit 21 includes a plurality of physical function keys 211 (i.e., real physical keys, to be distinguished from virtual keys), each function key 211 is configured to have at least one key value, that is, different key values may be output when different types of operations (such as short press, long press, double press, and continuous press, etc.) are performed on the function key 211; the setting unit 13 is configured to modify the mapping relationship between the key value and the function module 121, so that each function module 121 has a mapping relationship with at most one key value; The receiving unit 14 is communicatively connected with the transmitting unit 22. When the user presses a function key 211, the key value corresponding to the operation is sent by the transmitting unit 22 to the receiving unit 14 and forwarded to the control unit 12. The control unit 12 calls the function module 121 mapped to the key value and enables the user interface to respond to the control event corresponding to the function module 121.
[0015] Through the above scheme, after the present invention matches the remote control 2 with the electronic whiteboard 1, the mapping relationship between the function key 21 of the remote control 2 and the function module 121 built into the electronic whiteboard 1 system can be freely adjusted in the system setting interface. Specifically, each function key 21 has at least one key value, and the key value can be uniquely mapped to the function module 121 according to user needs, so that when the user performs a specific operation on a certain function key, the electronic whiteboard 1 can respond and execute the corresponding event, thereby realizing the customization of the function key 21 of the remote control 2, and the user can flexibly set it according to his own needs to meet the diverse user needs; for the manufacturer, only the system software needs to be modified to produce a standardized remote control 2, and the physical cost will not be increased; the communication and control relationship of the present invention is easy to implement at the code level without creative labor.
[0016] Specific embodiments of the present invention are shown below.
[0017] The default function of the function key 211 of the remote controller 2 is consistent with the function corresponding to the pattern printed on the surface of the key when leaving the factory, so as to achieve standardization during the production of the remote controller 2.
[0018] The above-mentioned setting unit 13 is configured to call the corresponding virtual remote control UI and display it on the top layer of the user interface when the user selects the "key mapping setting" function in the user interface of the display 11. After that, the user performs a certain operation on a certain function key 211 and selects the function module 121 to be mapped. The setting unit 13 records the key value corresponding to the operation and maps it with the function module 121 selected by the user; the mapped function key 211 is highlighted in the corresponding position of the virtual remote control UI, and the corresponding function description is displayed. For example, after the virtual remote control UI is called, the user short presses the function key A on the remote control 2 and selects the function module B corresponding to the screenshot function. After the mapping is completed, the position corresponding to the function key A in the virtual remote control UI is highlighted in red and "Screenshot" appears, reminding the user that the key has been set and its set function has been set.
[0019] Furthermore, the electronic whiteboard 1 further includes a prompt unit 15; the prompt unit 15 is configured to reset the "first operation after modification" flag of the system. When the user modifies the mapping relationship between the key value and the function module 121 through the setting unit 13, the prompt unit 15 resets the flag to 0; after receiving the key value sent by the transmitting unit 22, the receiving unit 14 first forwards it to the prompt unit 15. After receiving the key value, the prompt unit 15 checks the "first operation after modification" flag: if the flag is 1, the key value is directly forwarded to the control unit 12; if the flag is 0, the virtual remote control UI is called to display it on the top layer of the user interface, and all the function keys 211 of the edited functions are highlighted at the corresponding position of the virtual remote control UI and the corresponding function description of each function key 211 (after being edited) is displayed, and then the flag is modified to 1, and the corresponding key value is not forwarded to the control unit 12. Therefore, when the user performs any operation for the first time after completing the key function setting, the function corresponding to the operation will not be executed, but the function prompt after editing will be displayed in the user interface, which is user-friendly.
[0020] Secondly, when the above-mentioned virtual remote control UI is called by the setting unit 13, it disappears after the user completes the setting and clicks to confirm, ensuring that the user can complete the corresponding setting; when the virtual remote control UI is called by the prompt unit 15, it disappears after the preset display time or the user operates the remote control 2 again, avoiding long-term influence on the user's viewing of the content displayed on the electronic whiteboard.
[0021] The above-mentioned function key 211 has four key values corresponding to the operations of short press, long press, double click and continuous click. For example, the key values of function key A corresponding to short press, long press, double click and continuous click are A1, A2, A3 and A4 respectively, so that each function key 211 can complete four functions at most, greatly enriching the functions of small remote controls with fewer buttons.
[0022] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
