本发明实施例提供一种信息处理方法及电子设备, 用以解决现有技术中 配置有电容式触摸屏的电子设备, 存在的在电容式触摸屏表面有水覆盖时, 电子设备无法识别用户手指的所作用的触摸区域的技术问题。

根据每个感应点对应的电容差值, 确定电容式触摸屏上手指的触摸操作 所作用的触摸区域。
由于电容式触摸屏上的感应点在有手指触摸时, 该感应点对应的电容值 会减小, 在该感应点上有水覆盖时, 该感应点对应的电容值会增大, 所以, 本申请实施例中通过获取电子设备的电容式触摸屏上的每个感应点对应的当 前电容值, 再分别将每个感应点对应的当前电容值减去预设电容值, 获得每 个感应点对应的电容差值, 其中, 该预设电容值为在电容式触摸屏上没有水、 且没有手指的触摸操作时, 每个感应点中任一感应点对应的电容值; 根据每 个感应点对应的电容差值, 确定电容式触摸屏上手指的触摸操作所作用的触 摸区域, 从而有效地解决了现有技术中配置有电容式触摸屏的电子设备, 在 电容式触摸屏表面有水覆盖时, 电子设备无法识别用户手指的所作用的触摸 区域的技术问题, 实现了在电容式触摸屏上有水时, 电子设备依然可以确定 手指的触摸操作所作用的触摸区域, 从而使用户能够在表面有水的电容式触 摸屏上进行正常的触摸操作的技术效果。
为使本申请一实施例的目的、 技术方案和优点更加清楚, 下面将结合本 申请实施例中的附图, 对本申请实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本申请一部分实施例, 而不是全部的实施例。 基于 本申请中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
首先说明, 本文中出现的术语"和 /或", 仅仅是一种描述关联对象的关联 关系, 表示可以存在三种关系, 例如, A和 /或 B, 可以表示: 单独存在 A, 同时存在 A和 B, 单独存在 B这三种情况。 另外, 本文中字符" /,,, 一般表示 前后关联对象是一种 "或"的关系。
其次说明, 本文中出现的 "电子设备", 该 "电子设备" 可以是: 手机、 或平板电脑、 或车载电脑、 数码相机、 或游戏机等等, 且该电子设备配置有 电容式触摸屏。
再次说明, 对说明书附图 1A~1D中, 每条封闭曲线代表电容式触摸屏上 的电容差值相等的感应点的集合。 每条封闭曲线上的括号外的字母和数字的 组合为对应的封闭曲线的简称, 在每个字母后面括号中的数字代表对应的封 闭去曲线上的感应点此时的电容差值的参考值, 该参考值与实际的电容差值 成正比例关系, 具体地, 在该参考值为正值时, 对应的实际电容差值也为正 值;在该参考值为负值时,对应的实际电容差值也为负值;在该参考值为 0 时, 对应的实际电容差值也为 0。 例如: 图 1A中最外侧的封闭曲线则被简称为封 闭曲线 Al , 封闭曲线 Al上的所有感应点此时对应的电容差值的参考值都为 0; 图 1A中最内侧的封闭曲线则被简称为封闭曲线 F1 , 封闭曲线 F1上的所 有感应点此时对应的电容差值的参考值都为 60。 且, 在封闭曲线 Ai ( i为小 于 6的正整数) 以外的感应区域上的感应点的参考值都为 0。
实施例一
本实施例提供了一种信息处理方法, 如图 1所示, 该信息处理方法包括: 步骤 101 :获取电子设备的电容式触摸屏上的每个感应点对应的当前电容 值;
步骤 102: 分别将每个感应点对应的当前电容值减去预设电容值, 获得每 个感应点对应的电容差值, 其中, 该预设电容值为在电容式触摸屏上没有水、 且没有手指的触摸操作时, 每个感应点中任一感应点对应的电容值;
步骤 103: 根据每个感应点对应的电容差值, 确定电容式触摸屏上手指的 触摸操作所作用的触摸区域。
更详细地, 如图 1A所示, 图 1A为在电容式触摸屏上的一感应区域有手 指的触摸时, 该感应区域上的感应点的电容差值的参考值的情况示意图。 其 中, 在封闭曲线 A1内的感应区域有手指的触摸, 且位于封闭曲线 A1内的感 应点, 越靠近中心的感应点对应的电容差值的参考值越大, 例如: 封闭曲线 A1上的感应点对应的电容差值的参考值为 0,而封闭曲线 F1上的感应点对应 的电容差值的参考值为 60,—般,封闭曲线 F1内的感应点为手指的指心所作 用的感应点。由图 1A可知,在电容式触摸屏上的一感应区域有手指的触摸时, 该感应区域内的感应点的电容差值都为正值。
理论上, 在电容式触摸屏上的一感应区域有手指的触摸时, 该感应区域 内的感应点对应的电容差值的参考值都为正值, 且越靠近中心的感应点对应 的电容差值的参考值越大。 但实际上, 由于在手指和 /或该触摸区域上可能有 杂质, 而产生了误差信号, 使得在该区域上的感应点对应的电容差值的参考 值与理论值不相符, 此时, 应滤除这些误差信号。
在具体实施过程中, 在电容式触摸屏上有手指触摸时, 在手指对应的触 摸区域上的感应点对应的等电容差值的参考值可能有多种形状的分布, 包括 但不限于图 1A中的圓环状的分布, 也可能是椭圓状的分布, 或其他不规则的 封闭曲线状的分布。
更详细地, 如图 1B所示, 图 1B为在电容式触摸屏上的一感应区域有水 覆盖时, 该感应区域上的感应点的电容差值情况示意图。 其中, 在封闭曲线 A2内的感应区域有水覆盖, 且位于封闭曲线 A2内的感应点, 越靠近中心的 感应点对应的电容差值的参考值越小, 例如: 封闭曲线 A2上的感应点对应的 电容差值参考值为 0 ,而封闭曲线 E2上的感应点对应的电容差值参考值为 -40 , 一般, 封闭曲线 E2内的感应点上的水的厚度最厚。 由图 1B可知, 在电容式 触摸屏上的一感应区域有水覆盖时, 该区域内的感应点的电容差值的参考值 为负值。
在具体实施过程中, 在电容式触摸屏上有水覆盖时, 该感应区域上的感 应电对应的等电容差值的参考值可能有多种形状的分布, 包括但不限于图 1B 中的圓环状的分布, 也可能是椭圓环状的分布, 或其他不规则的封闭曲线状 的分布。
理论上, 在电容式触摸屏上的一感应区域有水覆盖时, 该感应区域内的 感应点对应的电容差值的参考值都为负值, 且越靠近中心的感应点对应的电 容差值的参考值越小。但实际上, 由于在手指和 /或该触摸区域上可能有杂质, 而产生了误差信号, 使得在该区域上的感应点对应的电容差值的参考值与理 论值不相符, 此时, 应滤除这些误差信号。
由于电容式触摸屏上的感应点在有手指触摸时, 该感应点对应的电容值 会减小, 在该感应点上有水覆盖时, 该感应点对应的电容值会增大。 所以, 本申请实施例中通过获取电子设备的电容式触摸屏上的每个感应点对应的当 前电容值, 再分别将每个感应点对应的当前电容值减去预设电容值, 获得每 个感应点对应的电容差值, 其中, 该预设电容值为在电容式触摸屏上没有水、 且没有手指的触摸操作时, 每个感应点中任一感应点对应的电容值; 再根据 每个感应点对应的电容差值, 确定电容式触摸屏上手指的触摸操作所作用的 触摸区域, 从而有效地解决了现有技术中配置有电容式触摸屏的电子设备, 存在的在电容式触摸屏表面有水覆盖时, 电子设备无法识别用户手指的所作 用的触摸区域的技术问题, 实现了在电容式触摸屏上有水时, 电子设备依然 可以确定手指的触摸操作所作用的触摸区域, 从而使用户能够在表面有水的 电容式触摸屏上进行正常的触摸操作的技术效果。
在本发明实施例中, 可选地, 步骤 103 , 包括:
确定在每个感应点中的电容差值为负值的感应点所组成的感应区域为第 一感应区域;
确定在每个感应点中的电容差值为正值的感应点所组成的感应区域为第 二感应区域;
根据第一感应区域与第二感应区域的位置关系, 确定电容式触摸屏上手 指的触摸操作所作用的触摸区域。
在具体实施过程中, 如图 1C所示, 封闭曲线 A3内的感应区域上的感应 点对应的电容差值参考值都为正值,则将封闭曲线 A3内的感应区域确定为第 一感应区域;封闭曲线 A4内的感应区域上的感应点对应的电容差值参考值都 为负值, 则将封闭曲线 A4内的感应区域确定为第二感应区域。 若第一感应区 域与第二感应区域不连接,则确定第一感应区域(即封闭曲线 A4内的感应区) 上有手指的触摸。
在本发明实施例中, 可选地, 该信息处理方法还包括:
若第一感应区域与第二感应区域不连接, 则确定第一感应区域为手指的 触摸操作所作用的触摸区域; 和 /或
若第一感应区域与第二感应区域连接, 且第二感应区域包围第一感应区 域, 则确定第二感应区域中的第一组感应点所围成的第三感应区域为手指的 触摸操作所作用的触摸区域, 其中, 第一组感应点为电容差值中由减小趋势 到增大趋势的拐点对应的感应点。
在具体实施过程中, 如图 1D所示, 封闭曲线 A5和封闭曲线 F5之间的 感应区域上所有感应点对应的电容差值的参考值都为负值,则确定封闭曲线 A 封闭曲线 A5和封闭曲线 F5之间的感应区域为第二感应区域; 封闭曲线 F5 内的感应区域上所有感应点对应的电容差值的参考值都为正值, 则确定封闭 曲线 F5内的感应区域为第一感应区域。 由于第二区域包围第一区域, 则确定 封闭曲线 D5内的感应区域为第三感应区域,且确定在第三感应区域上有手指 的触摸, 其中, 封闭曲线 D5上的感应点都为电容差值的参考值由减小趋势到 增大趋势的拐点对应的感应点。
在本发明实施例中, 可选地, 该信息处理方法还包括:
确定第二感应区域为有水覆盖的区域。 如图 1C所示, 可以确定封闭曲线 A4 内的感应区域为有水覆盖的区域; 如图 1D所示, 可以确定封闭曲线 A5 和封闭曲线 F5之间的感应区域为有水覆盖的区域。
在本发明实施例中, 可选地, 该信息处理方法还包括:
获取第二触摸区域的面积, 并在第二感应区域的面积大于预设面积时, 控制电子设备关机。
在具体实施过程中, 该预设面积大小为电容式触摸屏的整体面积的 50%~80%之间的任一值。 在确定第二感应区域的面积大于该预设面积, 可判 断电子设备落入水中 (或电子设备的触摸屏上有大量水覆盖), 此时, 为了防 止水进入到电子设备内部对其他电子器件 (如: 主板、 CUP、 内存等)造成 损害, 则控制电子设备关机。
