Embodiment Construction

[0032] Depend on figure 1 A driver-free analog keyboard input instruction set method for an interactive whiteboard system includes the following steps:

[0033] Step 1: Establish an interactive whiteboard system. The interactive whiteboard system includes a host computer, a display device, a main control device and a stylus;

[0034] Step 2: the HID keyboard simulation module is set in the main control device, and the HID keyboard bottom layer protocol is established in the HID keyboard simulation module;

[0035] Step 3: The main control device communicates with the host computer through the USB interface, and identifies the main control device through the HID driver, and regards the main control device as a HID keyboard;

[0036] Step 4: The host computer checks whether the communication with the main control device has been successful: if yes, then execute step 5; if no, execute step 3;

[0037] Step 5: Set up the simulated keyboard truth table KeyCode(i), the state set K...

Abstract

The invention discloses a driver-free analog keyboard input instruction set method of an interactive whiteboard system, and belongs to the electronic technical field. The method comprises the steps ofestablishing the interactive whiteboard system, setting an HID keyboard simulation module in the main control equipment, presetting a key execution process, simulating a keyboard truth table KeyCode(i) and a state set KeyState (i) used for representing a press-down or release state of the key according to the key execution process, so that the combined key function is realized, and the technicalproblem of realizing the drive-free simulation keyboard input instruction set on the interactive whiteboard system is solved. According to the present invention, the functional combination keys can be realized in the whiteboard interaction system through a universal HID underlying protocol, and any number of key combinations and key pressing or releasing time intervals can be set through a USB interface, so that the use efficiency of the interactive whiteboard is greatly improved.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a driver-free analog keyboard input instruction set method for an interactive whiteboard system. Background technique [0002] As the application of products in the field of interactive whiteboards becomes more and more extensive, the convenience and simplicity of its operation attract more and more attention from users. Some shortcut keys often used in the field of interactive whiteboards, such as opening the screen keyboard, PPT writing / erasing, Open the drawing board, etc. The realization of these functions basically requires the user to gradually realize by operating the keyboard or infrared photoelectric pen. The efficiency of use is far from the original intention of product design. There are three relatively easy-to-operate technologies on the market: [0003] The first type: there is a patent No. 2013101602136, titled "A drive-free positioning calibration guidance met...
