如题,在书写时直接用手掌擦除笔记之后往往会手掌离开了屏幕,但是由于红外触摸框不一定要手到达屏幕才识别,这就会导致擦完在相应位置留下一点点笔迹,会导致“擦不干净”的现象

值得注意的是 希沃白板似乎做了相应优化,在擦完后立即用手书写是写不上的

触摸高度问题

这就会导致擦完在相应位置留下一点点笔迹

预计触摸框自己处理有问题,在完全抬手之前就判断结束了。也就是此时的触摸尺寸出现快速的变更

希沃白板似乎做了相应优化,在擦完后立即用手书写是写不上的

希沃白板是通过完全的输入结束才允许从橡皮擦模式切换到笔书写模式的。判断输入完全结束的方法就是要求所有在橡皮擦模式中执行的 Down 全抬起之后才算输入完全结束
