Description

一种防止触摸屏上滑动误触发的方法、 系统和电子设备
技术领域
本发明涉及触摸屏技术领域, 具体地, 涉及一种防止触摸屏上滑动误触 发的方法及系统。
背景技术
随着技术的不断发展, 全触屏电子设备已成为全球主流趋势。 触摸屏是 结合显示器使用的一种绝对坐标定位系统,作为一种简单、便利的输入设备, 已经得到越来越广泛的应用。 随着使用越来越深入, 各种误触发的问题必将 越来越多, 屏幕滑动时产生的误触发就是其中一种。
很多用户, 特别是中老年人, 由于手指皮肤的老化、 角质等问题, 影响 到皮肤的导电能力,因此在滑动电容式屏幕的时候经常会意外打开某个应用, 造成不必要的损失。 对于电阻式触摸屏也会存在类似问题, 严重影响用户体 验。
一次正常的屏幕滑动过程一般大约在 Is以内,期间触摸屏感应器只会检 测到一次这样的过程: mousedown (按下)事件- >move (移动)事件- >mouseup (抬起) 事件。 而一次异常的滑动过程中, 触摸传感器可能会检测到 2次或 者更多的 mousedown ->move ->mouseu 过程,这可能会带来一些非预期的操 作。
发明内容
为了解决上述技术问题, 本发明公开了一种防止触摸屏上滑动误触发的 方法及系统, 能够防止触摸屏上的误触发操作。
本发明公开了一种防止触摸屏上滑动误触发的方法, 包括:
检测到触摸屏上的包括按下、 移动和抬起事件的触摸操作后, 不上报所 述抬起事件并保存; 检测所述抬起事件后的预设的时间 t内有无新的按下事件: 若有, 则对所述保存的抬起事件和所述新的按下事件不上报; 若无, 则上报所述保存的抬起事件。
较佳地, 所述预设时间 t大于触摸屏上的中断间隔时间, 小于 40ms。 较佳地, 10ms < t < 30ms„
较佳地, 所述预设的时间 t由用户设置。
本发明还公开了一种防止触摸屏上滑动误触发的系统, 包括: 检测模块, 设置为: 检测触摸屏上的包括按下、 移动和抬起事件的触摸 操作以及所述抬起事件后的预设的时间 t内有无新的按下事件;
保存模块, 设置为: 在所述检测模块检测到触摸屏上的包括按下、 移动 和抬起事件的触摸操作后, 保存所述抬起事件 ;
控制模块, 设置为: 在所述检测模块检测到所述新的按下事件后, 不上 报所述抬起事件, 并通知所述保存模块保存所述抬起事件, 以及, 在所述检 测模块检测到预设的时间 t内有新的按下事件时, 对所述保存的抬起事件和 所述新的按下事件不上报, 在预设的时间 t内无新的按下事件时, 上报所述 保存的抬起事件。
较佳地, 所述预设时间 t大于触摸屏上的中断间隔时间, 小于 40ms。 较佳地, 10ms < t < 30ms„
较佳地, 所述预设的时间 t由用户设置。
本发明还公开了一种电子设备, 包括上述的系统。
本发明实施例通过判断检测滑动操作过程中滑动事件结束后的预设时间 t 内有无下一次按下事件, 来近似滑动过程中有无意外抬起动作。 如果有, 忽略此次抬起动作, 从而避免应用的误触发。 附图概述
图 1本发明实施例中防止触摸屏上滑动误触发的方法流程图; 图 2忽略中间 mouseup和 mousedown事件的示意图;
图 3为本发明实施例中防止触摸屏上滑动误触发的系统结构框图。 本发明的较佳实施方式
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
方法实施例
本实施例公开了一种防止触摸屏上滑动误触发的方法, 如图 1所示, 包 括:
步骤 101、 设定门限值 t为 20ms。

步骤 102、 触摸传感器检测 mousedown (按下 ) 事件。
在触摸屏的滑动操作过程中, 触摸屏是通过检测 mousedown (按下)事 件来判断是否在进行滑动操作。
如果是电阻式触摸屏, 触摸传感器通过检测压力判定事件的发生; 如果 是电容式触摸屏, 触摸传感器通过检测电容来判定事件的发生。
步骤 103、 触摸传感器检测 mouseup (抬起)事件。
步骤 104、 触摸传感器在门限值 t内先不上报 mouseup事件, 检测是否 有下一个 mousedown事件。
在现有技术中, 触摸屏通过检测 mouseup (抬起) 事件来判断滑动操作 是否完成, 若检测到 mouseup (抬起) 事件则向系统上报。 在本实施例中, 在门限值 t内先不上报, 检测有无下一个 mousedown事件。
步骤 105、 如果有则忽略前一次的 mouseup和当前的 mousedown事件, 认为从上一次的 mousedown开始到当前的 mousedown事件是个连续的过程, 并将整个过程设为是当前事件 (如图 2 ) , 转第三步执行; 如果没有则上报 处理。
本实施例可用于所有触摸屏机型, 通过软件控制能有效防止误触发的发 生。 本发明结构简单, 易于实现, 有效提高用户体验。 实施例二
