Step s l 01, receiving the input stroke action;

Step s 102. When it is determined that the stroke action is an erase operation according to the stroke action or the stroke type, the correction is performed according to the erase operation, and the text corrected by the erase operation is displayed on the touch screen.

In this step, if it is determined that the stroke action is not an erase action according to the stroke action or the stroke type, Then it is judged that the stroke action is a writing action. Wherein, determining that the stroke action is an erase action according to the stroke action or the stroke type includes the following steps:

When the stroke model meets the first threshold condition, it is determined according to the stroke type that the stroke action is an erase action.

Meanwhile, when the stroke model meets the second threshold condition, the stroke operation is judged to be a writing action according to the stroke type.

The first threshold condition and the second threshold condition may be flexibly set, for example: the first threshold condition is that the set hand or the handwriting device covers the touch screen when the range is thick, and the second threshold condition is the set hand or handwriting device. The coverage of the touch screen is thin, and the thickness refers to a scale. Similarly, when the first threshold condition is that the range of the hand or the handwriting device covering the touch screen is fine, the second threshold condition is the set hand or the handwriting device. The range covering the touch screen is thick.

On the other hand, in the embodiment, determining the stroke action according to the stroke action or the stroke type is a stroke erasing action, including the following steps: when the stroke motion is within a certain range of the original stroke, the original stroke and/or the original stroke are reversed. Swiping, or moving frequently around the original stroke, determining that the stroke action is an erase action.

When the original stroke is swiped, it is judged that the stroke action is an erase action. For example: The user needs to correct "申" to "曱", and directly use the writing end 10 to perform a plurality of left and right swipes on the upper part of the "shen" word vertical stroke or in the erased portion. When the original stroke and/or the original stroke are swiped in a certain area, the system determines that the erase operation is performed, and the upper portion of the stroke is erased.

In the description of the above embodiment, the stroke action is judged according to the stroke action or the stroke type. No is the stroke erasing action; wherein the judgment of the stroke model actually means that the hand or the handwriting device port entity covers the range of the touch screen.
