Photo teaching terminal

Abstract

The invention discloses a photo teaching terminal, which comprises a processor, a memory, a writing trace receiving module, a USB interface, a first wireless receiving and transmitting module, a second wireless receiving and transmitting module, an HDMI interface, an RS232 interface and a power supply module of the first wireless receiving and transmitting module and the second wireless receiving and transmitting module, wherein the memory is used for caching data; the writing trace receiving module is used for receiving trace data of an electronic whiteboard; the USB interface is connected to the electronic whiteboard; the first wireless receiving and transmitting module is in wireless connection to external terminal equipment; the second wireless receiving and transmitting module is connected to an external network; the HDMI interface is connected to an external display device; and the RS232 interface is connected to the external display device. The photo teaching terminal disclosed by the invention, by changing data transmission between the whiteboard and a computer as well as data transmission between the computer and a projector as wireless transmission, can greatly facilitate connection, purify the space of a classroom or a meeting room and simplify operation switching while projecting.

Description

technical field [0001] The invention relates to a teaching terminal device, in particular to a Feitu teaching terminal. Background technique [0002] In the current teaching work and other work and life that require the use of electronic whiteboards, a large part of them uses infrared sensors to sense the moving track of the hand on the electronic whiteboard, and sends the data from the electronic whiteboard to the computer through the USB interface; Drawing software, according to the received data, draws the moving track of the hand on the whiteboard and displays it on the computer screen; the content of the computer screen is then transmitted to the projector through the HDMI / VGA interface cable of the computer; the light of the projector is projected to On the electronic whiteboard, restore the movement track of the shot. Since this process takes milliseconds, the human eye cannot detect the delay, and it feels as if the lines are written on the electronic whiteboard whi...
