Information terminal and touch control method thereof

Abstract

The invention discloses an information terminal, which comprises a touch screen module, a real-time operating system and a graphic interface operating system, wherein the touch screen module is used for generating touch information; the real-time operating system is used for reading the touch information which is generated by the touch screen module, converting the touch information into screen coordinate information, and determining that the real-time operating system processes the screen coordinate information or transmitting the screen coordinate information to the graphic interface operating system for processing according to the running state of the graphic interface operating system; and the graphic interface operating system is used for receiving the screen coordinate information of the real-time operating system, converting the screen coordinate information into mouse information, and executing corresponding mouse operation. The invention also discloses a touch control method of the information terminal. The information terminal provided by the invention is characterized by quick start of the real-time operating system and rich functions of the graphic interface operating system, so that the functions of the information terminal are richer, and performance is higher.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic information technology, and in particular, to an information terminal and a touch control method thereof. Background technique [0002] With the development of electronic information technology, the use of touch screens as input devices for information terminals greatly facilitates user operations. Today, touch screens are widely used in electronic devices such as tablet computers, mobile phones, MP3 and vehicle information terminals, and the future application fields will become more widespread. [0003] Take the car information terminal as an example, today's car information terminal has become more and more intelligent, providing users with a variety of functions, such as: car TV, car phone, car radio, MP3, CD, DVD player, reversing image, reversing radar And car bluetooth etc. The user can conveniently call the above-mentioned functions by touching the touch screen.

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the vehicle-mounted information terminal is generally based on an intelligent graphical interface operating system: for example: Windows, Linux, etc., the touch screen is used as an input function module under the operating system, and it needs to wait for the operating system to fully start and load the corresponding driver. After that, it can be used normally, and the intelligent GUI operating system generally has a slow startup time, which greatly affects the user's functional experience.

[0005] In order to solve the above problems, the inventor of the technical solution of the present invention proposes to use a vehicle-mounted information terminal with dual systems to compensate for the slow start-up speed of the vehicle-mounted information terminal. However, based on how different types of systems share the same touch screen and realize unified touch control is Issues that need to be further addressed
