Embodiment 1

[0038] Such as figure 1 Shown, a kind of handwriting input device suitable for Linux operating system, comprises DC power supply 7, stylus 1, touch screen 2, handwriting recognition module 3, it is characterized in that touch screen 2 is connected with handwriting recognition module 3 by four data lines 6 The handwriting recognition module 3 is connected to the Linux system 4 with a display terminal through the standard asynchronous serial communication interface 5; the DC power supply 7 is connected to the whole handwriting input device for power supply; the stylus 1 is a round rod type, and the front end is conical (like a general ballpoint pen) so that the user can write on the touch screen 2 .

[0039] The touch screen 2 is a four-wire resistive LCD separate pressure-sensitive touch screen.

[0040] The stylus 1 is a touch screen stylus made of metal aluminum.

Embodiment 2

[0042] Same as Embodiment 1, except that the handwriting recognition module 3 is connected to the embedded Linux system 4 with a display terminal through a standard asynchronous serial communication interface 5; the touch screen 2 is a four-wire capacitive LCD separate pressure-sensitive touch screen. The stylus 1 is a touch-screen stylus made of hard plastic material.

[0043] In the above-mentioned embodiment, a 3V2A DC power supply 7 is used to supply power to the chip and auxiliary circuits; the handwriting recognition module 3 uses a Hanvon HW006 chip.

Abstract

The invention relates to a handwriting input device suitable for a Linux operating system, which belongs to the technical field of input of electronic information. The handwriting input device comprises a DC power supply, a handwriting pen, a touch screen and a handwriting identification module. The handwriting input device suitable for Linux operating system is characterized in that the touch screen is connected with the handwriting identification module through a data line; the handwriting identification is connected with a Linux system or embedded Linux system with a display terminal through a standard asynchronous serial communication interface; the DC power supply is connected to the entire handwriting input device and supplies power for the handwriting input device; and the handwriting pen is in a round bar shape, and the leading end is in a circular cone shape, so that the user can write on the touch screen. The device of the invention adopts a modular structure, thereby having the advantages of simple hardware interface, and convenient debugging and installation; and the invention realizes the application on a mobile terminal. The invention has the advantages of short development cycle and strong practicability, has obvious edges in the aspects of development difficulty, workload and cost, and is suitable for handwriting input for a Linux platform of an X system and an embedded Linux platform with frame buffer.

Description

[0001] The technical field [0002] The invention relates to a handwriting input device suitable for a Linux operating system, which belongs to the technical field of electronic information input. Background technique [0003] With the continuous development of information technology, the touch screen has become a popular input device. By clicking and writing on the touch screen, the user can complete the interaction with the device. Due to the large population in our country and the unevenness of personnel at different levels of education, the handwriting input method based on the touch screen is more suitable for our national conditions. Linux is a UNIX-like operating system with the network as the core that supports multi-user, multi-task, multi-thread, and multi-CPU , is one of the most dynamic operating systems out there. In terms of stability and reliability, it has the characteristics of a server operating system. It is often used to build various server platforms and ...
