一种智慧互联黑板避免数据误传输的方法及系统
By acquiring data from touch detection points, the system determines the conditions under which the pen/eraser falls, distinguishing between normal writing/erasing and object drop, thus solving the problem of data mistransmission caused by object drop in smart interconnected blackboards and ensuring the accuracy and reliability of data transmission.

AI Technical Summary
When objects fall during writing or erasing on existing smart interconnected blackboards, it can cause incorrect data transmission and display on the electronic display screen. Current technology makes it difficult to distinguish between normal writing/erasing trajectories and object falling trajectories.
By acquiring the number, historical location, and timestamp data of touch detection points, the movement trajectory direction, acceleration, and state of the touch detection points can be determined, distinguishing between normal writing/erasing and object drop, and filtering out trajectories caused by object drop.
It achieves accurate and reliable data interaction between the smart interconnected blackboard and the electronic display screen, avoiding mis-display or mis-erasing caused by data mis-transmission.
