Problems solved by technology

However, when the user uses the coordinate positioning device to input text, the coordinate positioning device is placed on the side of the display, and the coordinate positioning device itself cannot display the user's coordinate information, but directly displays it on the display, so that the user can coordinate their hands and eyes when writing. Poor performance, difficult to control the size and arrangement of the written words, inconvenient to use

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] The coordinate positioning device can be a handwriting board or a drawing board. In an embodiment of the present invention, the coordinate positioning device is a handwriting board, and the coordinate indicator is an electromagnetic pen. The electromagnetic pen and the handwriting board 2 can be connected wirelessly or through cables. Such as figure 1 As shown, it is a schematic diagram of the appearance of the coordinate positioning device for real-time display of trajectory information of the present invention, including: a communication port 1 for connecting the tablet 2 with a computer, which is a USB interface in this embodiment, and the device is connected to the computer through the USB interface connect. The tablet 2 is used to detect the position information written by the electromagnetic pen on it and convert it into coordinate information, and transmit th...

Abstract

The invention discloses an electromagnetic coordinate positioning device for displaying an input locus in real time, and belongs to the field of external input equipment of computers. The device is provided with a main control circuit for detecting position information of a coordinate indicator and converting the position information into coordinate information, and the device transmits signals to a computer through a communication port. A cholesterol liquid crystal film for displaying the locus information input by the coordinate indicator in real time is covered on the upper surface of the coordinate positioning device. When a user inputs the locus information on the coordinate positioning device, the coordinate positioning device displays the locus information of the coordinate indicator in real time, and supplies the coordinate information of the coordinate indicator to the computer so as to realize computer input of the coordinate information on the premise of according with the writing habit of the user.

Description

technical field [0001] The invention belongs to the field of computer external input devices, and relates to a coordinate positioning device, in particular to a coordinate positioning device capable of displaying input tracks in real time. Background technique [0002] Computer is one of the most important scientific and technological achievements in the history of human technological development, and it has been widely used now. As a computer input device, the coordinate positioning device has the characteristics of fast and convenient input, solves the difficult problem of inputting Chinese characters and letters for people of different levels, and has extensive use value. The coordinate positioning device has become a typical representative of non-keyboard input, and more and more people accept and use handwriting input as a way of using a computer. The coordinate positioning device is usually equipped with a special coordinate indicator, such as an electromagnetic pen. ...
