示例性地，若第一书写数据包括书写点的坐标值，可以比较书写模板与书写笔迹中对应的书写点的坐标值，判断这两个坐标值之间的差值，如距离差值和/或角度差值是否在预设范围内，若为是，则表明不存在误差，反之，则表明存在误差。具体地，还可以根据书写笔迹及书写模板中对应的起始点即原始点的坐标值，以及对应的其他书写点的坐标值，以及误差公式，得到误差值，并可根据该误差值的大小，确定匹配结果。

步骤S406，根据所述误差，确定匹配结果。
示例性地，可以根据上述确定的误差值，来确定匹配结果。匹配结果可以包括不同的匹配程度。匹配程度可以与误差值范围对应。
具体地，可以根据误差值落入的误差值范围，确定与其对应的匹配程度。并输出与该匹配程度对应的提示信息。
步骤S407，输出与所述匹配结果对应的提示信息。
示例性地，可以向与书写笔连接的书写工具输出提示信息。例如，书写工 具中可以配置有指示灯。可以根据确定的匹配程度，输出与匹配程度对应的指示灯驱动信息，该驱动信息用于驱动指示灯显示与匹配程度对应的格式。例如，若匹配程度高，则驱动指示灯显示绿色，若匹配程度低，则驱动指示灯显示红色等。又例如，若匹配程度高，则驱动指示灯显示亮度高，若匹配程度低，则驱动指示灯显示亮度低等。
通过上述方式，书写板可以实时输出匹配结果。使用户在实时书写时，能够得到实时练字反馈，提升了用户体验。

书写板可以根据书写工具发送的状态信息，确定用户的书写姿势与练习模式是否相匹配。其中，练习模式可以包括练习书法模式、练习钢笔模式、练习铅笔模式等，不同的练习模式对应的书写姿势不同。进一步地，不同的书写姿势对应不同的倾斜度。则可以根据获取的倾斜度确定是否与当前练习模式相匹配。若不匹配，则可以向书写工具发送警示信息，例如发送指示灯驱动信息，以驱动警示灯进行闪烁等；或者，向用户终端发送警示信息，以使用户终端显示当前练习模式匹配的持握姿势，以提示用户对当前持握姿势进行矫正。
