Problems solved by technology

[0002] In the existing intelligent display all-in-one machine, the handwriting on the touch whiteboard is generally erased after touching the screen with the hand in the erasing mode. The area to be erased is determined by touching the touch frame of the whiteboard to obtain the touch width of a single point. In practice During use, multiple touch points will be generated after the hand touches the touch whiteboard. The existence of multiple touch points will lead to deviations in the touch width of a single point acquired, resulting in large and small erasing areas and low erasing accuracy.

Embodiment Construction

[0043] The embodiments of the present invention will be described in detail below.

[0044] like figure 1 , figure 2 As shown, this embodiment discloses a method for erasing handwriting applied to a smart whiteboard. The smart whiteboard in this embodiment is a touch smart electronic whiteboard that can realize touch and writing functions, and the smart whiteboard can be an infrared touch based infrared touch The electronic whiteboard, the smart whiteboard is provided with a touch frame, and the opposite sides of the touch frame of the smart whiteboard are respectively provided with an infrared emitting tube and an infrared receiving tube, and the touch operation on the smart whiteboard is detected by the infrared emitting tube and the infrared receiving tube;

[0045] Wherein, the handwriting erasing method includes the following steps:

[0046] S100, the nib of the eraser pen is in contact with the smart whiteboard;

[0047] S200. Detect pressure sensitivity data corresp...

Abstract

The invention discloses a handwriting erasing method and system applied to an intelligent whiteboard. The handwriting erasing method comprises the following steps that making a pen point of an eraserpen in contact with the intelligent whiteboard; detecting pressure sensing data corresponding to the pressure borne by the pen point of the eraser pen; transmitting the pressure-sensitive data to theintelligent white board; enabling the intelligent whiteboard to display the erasing area corresponding to the pressure sensing data around the point of the eraser pen according to the pressure sensingdata; enabling the pen point of the eraser pen to slide on the intelligent white board to remove the writing track covered by the erasing area, the handwriting erasing method is high in accuracy of determining the size of the erasing area, and the dynamic change of the erasing area can be achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent touch control, and more particularly, to a method and system for erasing handwriting applied to an intelligent whiteboard. Background technique [0002] In the existing intelligent display all-in-one machine, the handwriting on the touch whiteboard is generally erased by touching the screen with the hand in the erasing mode. The erased area is determined by the touch width of a single point obtained by touching the touch frame of the whiteboard. In use, multiple touch points will be generated after the hand touches the touch whiteboard. The existence of multiple touch points will lead to deviations in the acquired touch width of a single point, resulting in the erased area being large and small, and the erasing accuracy is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method and system for erasing handwriting applied to an intelligent whiteboard....
