触摸屏触点处理方法、 装置及终端
技术领域
本发明涉及通信领域， 具体而言， 涉及一种触摸屏触点处理方法、 装置 及终端。
背景技术
触摸屏是一种附加在显示器表面的透明介质， 目前主要有几种类型的触 摸屏， 它们分别是： 电阻式、 表面电容式和感应电容式、 表面声波式、 红外 式等等。 其中， 电容式触摸屏应用较为广泛， 主要涉及到通信和电子消费品， 如： 智能手机、 移动电话、 多媒体播放器、 PAD等。 电容式触摸屏是通过感 应人体触摸所产生的电容变化而判断触摸点的， 它具有两组信号线： 驱动线 与感应线， 驱动线发射信号， 感应线侦测电容值的变化。 当手指触摸在金属 层上时， 由于人体电场的存在， 手指和触摸屏表面形成一个耦合电容， 对于 高频电流来说， 电容是导体， 于是手指从接触点吸走一个很小的电流， 影响 了触摸点附近两个电极之间的耦合， 从而改变了这两个电极之间的电容量。 检测互电容大小时， 驱动线方向的电极依次发出激励信号， 感应线方向的所 有电极同时接收信号， 这样可以得到所有横向和纵向电极交汇点的电容值的 变化， 即整个触摸屏的二维平面的电容大小。 根据触摸屏的二维电容变化量 数据， 可以计算出每一个触摸点的坐标。 因此， 屏上即使有多个触摸点， 也 能计算出每个触摸点的真实坐标。
近年来， 随着手持式触摸屏移动通讯终端技术的进步， 使用手持式触摸 屏移动通讯终端的用户日益增加。 根据触摸屏的工作原理， 充电器、 液晶显 示器（ Liquid Crystal Display, 简称为 LCD )等对其都会有一定的干扰， 另外， 低端触摸屏本身的抗干扰能力就较差， 从而造成触摸时产生抖动， 严重影响 用户体验。

本发明的较佳实施方式
下文中将参考附图并结合实施例来详细说明本发明。 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组合。
本发明实施例提供了一种触摸屏触点处理方法， 图 1是本发明实施例的 触摸屏触点处理方法的流程图。 如图 1所示， 该流程包括如下步骤：
步骤 S 102 , 检测触摸屏上的触点一；
步骤 S104, 确定对触摸屏的操作为从触点一至触点二的滑动， 其中， 触 点二与触点一之间的距离超过第一预定阔值；
步骤 S106, 将位于触点一到触点二的滑动路径上的一个或多个触点三进 行上报， 其中， 触点三与触点一的距离小于第一预定阔值。
上述步骤， 通过触点之间的距离是否超过预定阔值的防抖算法对触摸屏 进行防抖处理。 考虑到相关技术中类似充电器、 液晶显示等终端应用对触摸 屏触摸的干扰， 使对触摸屏的触摸会产生抖动， 以及触点与触点之间跳跃， 影响触摸的效果， 釆用上述处理， 不仅能够有效地过滤掉非实际触摸的抖动 点， 而且当检测到防抖范围外的触点二时， 依次上报触点一和触点二间滑动 轨迹上的触点， 产生的非滑动轨迹上的触点不再上报， 实现从触点一到触点 二的平滑过渡， 有效地提高了用户体验。
优选地， 确定对触摸屏的操作为从触点一至触点二的滑动时可以釆用多 种处理方式， 例如， 可以釆用以下较为简单的处理方式： 依次判断在触点一 之后的一个或多个触点与触点一之间的距离是否超过第一预定阔值； 在判断 的结果为否时， 依次保存一个或多个触点， 即暂时确定该一个或多个触点为 抖动点， 因为在触点一和非抖动点之间滑动路径上产生的触点可能是真正滑 动产生的。 对这些在第一预定阔值范围内的抖动点进行保留， 保留的预定个 数可以为M。 当超过 M个时， 新的增加， 旧的去除， 直到判断到与触点一之 间距离超过第一预定阔值的第一个触点 （即： 非抖动点） ， 确定该第一个触 点为触点二， 以及确定对触摸屏的操作为从触点一到触点二的滑动。 需要说 明的是， 上述第一预定阔值可以根据实际情况的不同而不同， 例如， 该实际 情况包括触摸屏的大小， 以及触摸屏的灵敏度等。
将位于触点一到触点二的滑动路径上的一个或多个触点三进行上报时可 以釆用以下处理： 依据触点一到触点二的滑动路径， 从依次保存的一个或多 个触点中确定一个或多个触点三， 即保留触点一到非抖动点的滑动路径上的 其它触点； 将确定的一个或多个触点三依次进行上 即上 ^艮其坐标。 在该 非抖动点 （即触点二） 坐标上报前， 上报保留的触点一到非抖动点滑动路径 上的触点坐标， 使得在触摸屏上的滑动有一个明显的平滑过渡， 不表现为突 然由一个点到另一个点的跳跃。 为了充分降低终端的功耗， 即在不必要损耗的情况下， 尽量减少终端的 应用， 例如， 可以在确定对触摸屏的操作为从触点一至触点二的滑动之后， 还包括： 停止对触点二之后的触点与触点一之间的距离是否超过第一预定阔 值进行的判断， 即关闭防抖算法， 减少终端的应用， 有效地节省终端的功耗。
另外， 在确定对触摸屏的操作为从触点一至触点二的滑动之后， 还包括 如何确定该滑动操作的结束， 确定的方式也可以有多种， 在此提供一种较为 简单的实现方式， 先依次保存在触点二之后检测到的一个或多个触点； 判断 保存的触点的数量是否达到预定数目 N; 在判断结果为是的情况下， 判断保 存的 N个触点中的最后一个触点与第一个触点间的距离是否小于第二预定阔 值； 在小于第二预定阔值的情况下， 确定滑动到保存的第 N个触点停止。
而在判断保存的 N个触点中的最后一个触点与第一个触点间的距离不小 于第二预定阔值的情况下， 还包括： 更新保存的 N个触点， 其中， 先顺序移 位将保存的 N个触点中的第一个触点覆盖，增加接着在第 N个触点之后产生 的一个触点， 组成更新后的 N个触点； 重复判断更新后的 N个触点中的第 N 个触点与第一个触点间的距离是否小于第二预定阔值， 直到判断到小于第二 预定阔值， 才确定滑动操作停止。在判断滑动停止后，再次启动防抖算法（即 上述的判断处理） ， 起到不需要时关闭， 需要时启动的效果。

基于上述模块， 触摸屏防抖及平滑过渡的方法大致包括如下步骤： 步骤 S1 , 启动防抖算法， 设置防抖的阔值 L1 , 需保存的触点个数 M, 获得首个触点坐标并分别保存为 pre— X, pre_y。
步骤 S2 , 继续侦测下一触点坐标， 并计算该点与原点 （pre— X, pre_y ) 的间距 dl , 如果 dl在阔值 L1内， 说明该点有可能是抖动产生的， 暂视为无 效点并保存， 上报原点坐标（pre— X, pre_y ) , 重复步骤 S2。
步骤 S3 ,如果此次侦测到的触点与原点间距超过阔值 L1 ,说明该点是非 抖动产生的， 为有效点， 是手指从静止点击到滑动的过程。 首先将保存的暂 视为无效的点中抖动较大的点排除，将原点至该有效点滑动路径内的点保留， 并按实际触摸的先后顺序上报， 上报完后再上报这个有效的触摸点坐标， 并 关闭防抖算法。 步骤 S4, 继续侦测下一触摸点， 将该点坐标保存到 buf2中， 并上报该点 坐标。
步骤 S5 , 重复步骤 S4, 如果保存在 buf2中的坐标个数超过 N个， 则计 算保留的第 N个触点和第一个触点间的间距是否在阔值 L2内， 如果不在则 继续重复步骤 S4, 如果在阔值 L2 内， 说明用户从滑动进入停止， 则启动防 抖算法， 进入步骤 Sl。
通过上述实施例及优选实施方式， 不仅可以有效实现触摸屏防抖效果， 而且在手指从静止到滑动过程中实现平滑的过渡， 没有跳点的感觉， 很好地 改善了用户体验。
下面结合附图对本发明优选实施方式进行说明。
图 10是根据本发明优选实施方式的触摸屏防抖及平滑过渡方法流程图， 如图 10所示， 该方法包括如下步骤：
步骤 S1002 , 启动防抖算法， 首次触摸或滑动后手指静止时都会启动防 抖算法。
步骤 S1004, 侦测首个触摸点坐标， 分别将该坐标的 X, y值分别赋值给 全局变量 pre— X和 pre_y, 并上 4艮该触摸点坐标。 （pre— x, pre_y)将作为原点坐 标， 用于判断后续触摸点是否在防抖范围内。
步骤 S1006, 继续侦测下一触摸点， 计算该点与原点（pre— X, pre_y ) 间 的距离 dl。
步骤 S1008, 判断两点距离 dl是否在阔值 L1的范围内。 比较 dl和 L1 的大小， 如果 dl ： L1 , 说明该点在防抖范围内， 否则说明该点已超过防抖范 围。
步骤 S1010, 如果该触点在防抖范围内， 则保存该触点坐标到 bufl中。 如果 bufl中保存的个数超过 M个， 就从 bufl的起始位置依次让新值覆盖掉 旧值进行保存。
步骤 S1012 , 如果该点被判断在防抖范围内， 则暂时认定为无效点， 上 报保留的原触点坐标（pre_x, pre_y ) , 重复步骤 S1006。
步骤 S1014, 如果该点已超过防抖范围， 则将 bufl中那些抖动较大的点 过滤掉， 将原点至该点间滑动路径上的触点坐标保留， 并按实际触摸的先后 顺序进行上报。理论上上报的这些点应该是在防抖范围内手指滑动产生的点。 步骤 S1016, 当上报完保留的防抖范围内的部分点后， 上报当前侦测到 的触点坐标， 即在防抖范围 L1外的第一个触摸点。
步骤 S1018, 关闭防抖算法。 此时手指已经从静止状态过渡到滑动状态。 步骤 S1020, 继续侦测下一触摸点， 将该点坐标保存到 buf2中， 并上报 该点坐标。 此时手指处于滑动过程中， 保存坐标的目的是用于判断手指是否 由滑动转换为静止状态。 判断保存到 buf2的坐标个数是否达到 N个。
步骤 S1022, 如果 buf2中保存的点的个数达到 N个， 则计算 buf2中第 N 个点与第一个点之间的距离 d2。 步骤 S1024, 判断距离 d2是否在阔值 L2的范围内。 如果 d2>L2, 则说 明手指仍处于滑动状态， 重复步骤 S1020, 如果 d2 L2, 则说明手指从滑动 状态转换到了静止状态， 则重新启动防抖算法。
通过上述实施例及优选实施方式， 不仅可以起到很好的防抖效果， 而且 在用户从手指静止到滑动的过程中可以平滑的过渡， 给用户更流畅的感觉， 提高用户体验。

9、 根据权利要求 7或 8所述的装置， 其中， 所述上报模块包括： 第二确定单元，设置为依据所述触点一到所述触点二的滑动路径，从 依次保存的所述一个或多个触点中确定所述一个或多个触点三； 上报单元， 设置为将确定的所述一个或多个触点三依次进行上报。
10、 根据权利要求 7或 8所述的装置， 其中， 所述确定模块还包括： 停止单元，设置为停止对所述触点二之后的触点与所述触点一之间的 距离是否大于所述第一预定阔值进行的判断。
11、 根据权利要求 7所述的装置， 还包括： 保存模块，设置为依次保存在所述触点二之后检测到的一个或多个触 点； 第一判断模块， 设置为判断保存的触点的数量是否达到预定数目 N; 第二判断模块，设置为在第一判断模块的判断结果为是的情况下，判 断保存的 N 个触点中的最后一个触点与第一个触点间的距离是否小于第 二预定阔值； 第二确定模块，设置为在所述第二判断模块的判断结果为小于等于所 述第二预定阔值的情况下， 确定所述滑动到保存的所述第 N个触点停止。
12、 根据权利要求 11所述的装置， 其中， 还包括： 更新模块，设置为在判断保存的 N个触点中的最后一个触点与第一个 触点间的距离大于所述第二预定阔值的情况下， 更新保存的 N个触点，其 中，先顺序移位将保存的 N个触点中的第一个触点覆盖， 然后增加接着在 第 N个触点之后产生的一个触点， 组成更新后的 N个触点； 重复模块，设置为重复判断更新后的 N个触点中的第 N个触点与第一 个触点间的距离是否小于等于第二预定阔值 ,直到判断到小于等于所述第 二预定阔值， 才确定滑动操作停止。
13、 一种终端， 包括权利要求 7至 12中任一项所述的装置。
