AI Technical Summary
Technical Problem
Current non-high-precision touch frames in interactive boards struggle to accurately determine the type of stylus, ensure consistent touch area, and effectively erase handwriting due to limited utilization of touch point information.
Method used
A method and device for erasing handwriting that utilizes a high-precision touch frame to acquire and process touch point information, including coordinates, height, width, and rotation angle, to determine an erasing geometry shape matching the touch object, enabling precise erasure of handwriting based on touch point analysis.
Benefits of technology
Enhances the erasing efficiency and precision of handwriting by accurately matching the erasing geometry shape to the touch object, improving the erasing effect on interactive boards.
