Embodiment 1

[0034] Such as figure 2 As shown, it is a schematic structural diagram of a simulated keyboard in which a single frame of the present invention is applied to an interactive electronic whiteboard and is pulled outward to form a keyboard area. In this embodiment, the simulated keyboard device includes a camera A and a camera B, a key analysis control module, a computer and touch screen. The key analysis control module is arranged in the chip of the touch screen and connected with the computer signal.

[0035] The camera A and the camera B are installed on the upper frame 1 of the touch screen, and at the same time, the lower frame 3 of the touch screen is pulled downward, so that the lower frame 3 is separated from the display area; the left frame 2 and the right frame 4 of the touch screen are extended correspondingly in the Y direction, and are connected with the touch screen A keyboard area 7 is formed between the lower frame 3 and the edge of the display area, and the touc...

Embodiment 2

[0041] Such as image 3 As shown, it is a schematic structural diagram of an analog keyboard where the four frames of the present invention are pulled outwards to form a keyboard area of ​​an interactive electronic whiteboard. In this embodiment, the analog keyboard device includes a camera A and a camera B, a key analysis control module, a computer and touch screen. The key analysis control module is installed in the software of the computer.

[0042] The camera A and the camera B are installed on the upper frame 1 of the touch screen. At the same time, pull the upper frame 1 of the touch screen upward, the left frame 2 of the touch screen to the left, the lower frame 3 of the touch screen downward, and the right frame 4 of the touch screen to the right. keyboard area 5 is formed between them; keyboard area 6 is formed between the left frame 2 of the touch screen and the display area; keyboard area 7 is formed between the lower frame 3 of the touch screen and the display ar...

Embodiment 3

[0049] Such as Figure 5 As shown, it is a schematic structural diagram of an analog keyboard where the four frames of the present invention are pulled outwards to form a keyboard area of ​​an interactive electronic whiteboard. In this embodiment, the analog keyboard device includes a camera A and a camera B, a key analysis control module, a computer and touch screen. The key analysis control module is installed in the software of the computer.

[0050] The camera A is installed on the upper frame 1 of the touch screen, and the camera B is installed on the right frame 4 of the touch screen. At the same time, pull the upper frame 1 of the touch screen upward, the left frame 2 of the touch screen to the left, the lower frame 3 of the touch screen downward, and the right frame 4 of the touch screen to the right. A keyboard area 5 is formed between them; a keyboard area 6 is formed between the left frame 2 of the touch screen and the display area; a keyboard area 7 is formed bet...

Abstract

The invention discloses a simulated keyboard device, which comprises a key analysis control module, a computer and a touch screen, wherein the touch screen consists of enclosed outer borders. The simulated keyboard device further comprises at least two position acquisition modules which are arranged on the borders of the touch screen, and at least one keyboard area, wherein the keyboard area is provided with functional touch keys, and is arranged between a display area and the outer borders of the touch screen; and the functional touch keys, the position acquisition modules and the key analysis control module are in signal connection. The invention also discloses an implementation method for the simulated keyboard device. In the simulated keyboard device and the implementation method thereof, one or more rows of keys are arranged under the condition of not increasing the cost, so various frequently-used menu keys are more conveniently and quickly operated on the display screen, commands are more conveniently and quickly input, and the interactivity and convenience of an electronic whiteboard are greatly improved.

Description

technical field [0001] The invention relates to touch button technology, in particular to an analog keyboard device applied to an interactive electronic whiteboard and a realization method thereof. Background technique [0002] At present, most interactive electronic whiteboards perform keyboard simulation in the display area, and a small part of them set some buttons (such as shortcut keys: up, down, left and right buttons) outside the touch area. But both have disadvantages. The former occupies precious resources of the display area and covers part of the display content; the latter needs to provide a special circuit for electronic scanning of the keys. [0003] figure 1 It shows the buttons set on the touch screen in the prior art. Generally, the method of setting a soft keyboard on the screen is adopted, and the scanned coordinate information is sent to the button analysis control module through the touch scanning device and then responds to the computer. However, from...
