Problems solved by technology
But in fact, the existing infrared touch screen has no way to identify different touch trajectories, and the display status of the content written by different touch objects is the same, so there is no way to achieve differentiated writing
In addition, the existing infrared touch screen has no way to identify whether the user is writing with a hand or with a stylus

Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0040] see figure 1 , which is a schematic flowchart of a smart writing method provided by an embodiment of the present invention.
[0041] Described intelligent writing method comprises:
[0042] S11. The infrared touch screen detects a touch track generated by a touching object on the infrared touch screen;
[0043] S12. The infrared touch screen receives a first infrared reception signal corresponding to the first infrared transmission signal sent by the ...

Disclosed are a smart writing method, an infrared touch screen, and a smart writing system. The method comprises: an infrared touch screen detects a touch trajectory generated on the infrared touch screen by a touch object; receive a first infrared receiving signal corresponding to a first infrared transmitting signal sent by the touch object; identify the touch object according to the wavelength of the first infrared receiving signal; determine, according to a pre-configured correspondence between different touch objects and handwriting display states, a handwriting display state to be configured of the identified touch object; display a handwriting corresponding to the touch trajectory and having the handwriting display state to be configured. According to the present invention, the infrared touch screen can identify touch objects so that handwritings of different touch objects are displayed in different handwriting display states, thereby implementing differential writing and the differentiation between a hand and a pen.
Description
technical field [0001] The invention relates to the field of touch technology, in particular to an intelligent writing method, an infrared touch screen and an intelligent writing system. Background technique [0002] With the development of touch technology, touch input devices (such as touch pens) used in conjunction with infrared touch screens (such as digital signage for automatically distributing multimedia information or educational equipment for interacting with students in classrooms, etc.) have appeared. [0003] The existing infrared touch screen can acquire the touch track of the touch object on the infrared touch screen, but there is no way to identify the touch track of different touch objects and display them differently. [0004] For example, different students answer on the infrared touch screen and the teacher writes the correct answer on the infrared touch screen. In order to clearly distinguish the writing content of different people, the ideal solution is...
