Embodiment Construction
[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] The main solution of the embodiment of the present invention is: when it is detected that the writing application is started, collect valid touch point data; confirm whether the touch point data is writing data; The above touch point data is delivered to the preset special channel of the driver layer for processing.
[0036] Because the message processing method of the existing infrared touch screen is too cumbersome, the efficiency of message processing is low, which leads to the technical problem of loss of touch data.
[0037] The present invention provides a solution. When a user performs a writing operation through an infrared touch screen, the message of the writing operation is processed through a preset special channel of the driver layer to avoid passing through the terminal system operation layer, the...

The invention discloses a writing touch recognition method based on an infrared touch screen, which includes: collecting effective touch point data when it is detected that the writing application is started; When the point data is writing data, deliver the touch point data to a preset special channel of the driver layer for processing. The invention also discloses a device and a readable storage medium. In the present invention, when a user performs a writing operation through an infrared touch screen, the message of the writing operation is processed through the preset special channel of the driver layer to avoid passing through the terminal system operation layer, thereby improving the data processing efficiency and avoiding the beneficial effect of message loss when the message is reported. .
Description
technical field [0001] The present invention relates to the technical field of touch screen writing recognition, in particular to a writing touch recognition method, device and readable storage medium based on an infrared touch screen. Background technique [0002] With the development of science and technology, touchable LCD screens are widely used in teaching, conferences and other fields. Infrared touch technology is the most widely used in large-size touch screens, which basically accounts for more than 95% of large-size touch screens. The original infrared screen shines in large size due to its cost advantage, but the touch accuracy is slightly lower than other technologies. With the development of technology, the accuracy of infrared touch technology has been greatly improved, and the accuracy is close to that of capacitive screens. The user's experience requirements for writing operations are gradually improving. There are many types of writing applications on the l...
