本发明一实施例利用用户在触摸显示单元上的滑动距离和滑动时间来 计算滑动速率, 当滑动速率大于等于预定的解锁判定速率, 即可解锁, 所 以在用户界面锁定状态时, 只要点击触摸显示单元, 就可以按照任何轨道 进行滑动, 也没有任何目标点的限定, 所以不用在解锁界面上设置预定轨 道以及预定目标, 大大降低了技术复杂度, 也使得操作更为随意, 用户体 验好, 同时, 因为还要判定滑动速率是否达到预定速率值, 才解除用户界 面的锁定状态, 所以可以有效防止误解锁。
进一步, 本发明一实施例中还当滑动速率没有达到预定速率时, 将计 时单元清零, 并清除滑动轨迹, 并保持用户界面锁定状态, 所以当用户下 次解锁时, 计时单元可从零开始计, 然后重新形成滑动轨迹, 重新计算滑 动速率。 附图说明

图 2为本发明一实施例中的计算滑动速率的示意图;
图 3为本发明一实施例中的解锁装置的功能框图。 具体实施方式
本发明一实施例提供一种解锁方法, 该方法应用于电子终端上, 该电 子终端包括触摸显示单元, 且触摸显示单元能够接收用户的触摸输入操作。 该电子终端例如为手机、 平板电脑或其他手持终端等。 请参考图 1 , 图 1为 本实施例中的解锁方法流程图。
如图 1所示, 该方法包括:
步驟 101: 当电子终端处于用户界面锁定状态时,检测操作体在触摸显 示单元上的操作;
步驟 102: 响应操作, 在触摸显示单元上形成滑动轨迹, 并记录形成滑 动轨迹的时间;
步驟 103: 计算滑动轨迹的距离;
步驟 104: 基于距离和时间, 计算形成滑动轨迹的速率;
步驟 105: 判断速率是否大于或等于预定速率;
步驟 106: 当速率大于或等于预定速率时, 解除用户界面锁定状态。 其中, 在步驟 101 中, 电子终端还处于用户界面锁定状态, 这时如果 用户想要解除用户界面锁定状态时, 就可以使用操作体, 例如手指或者触 摸笔在触摸显示单元上进行操作, 例如用户使用手指在触摸显示单元上进 行滑动, 这时, 响应该滑动, 在触摸显示单元上形成任意形状的滑动轨迹, 该滑动轨迹可以直线显示在触摸显示单元上, 也可以不显示在触摸显示单 元上, 该滑动轨迹为连续的线条, 并具有起始位置和终止位置。 进一步, 响应该滑动, 当检测到手指在触摸显示单元上的起始位置时, 就开始计时, 例如使用计时器进行计时, 其中, 起始位置在触摸显示单元上的位置可以 是触摸显示单元上的任意位置, 即, 该起始位置可以是点击触摸显示单元 上的任意位置所产生的触摸点。
然后, 当检测到手指在触摸显示单元上的终止位置时, 就停止计时。 判定用户是否已经停止本次操作, 可以检测是否存在终止位置, 具体的, 例如可以判定手指是否离开触摸显示单元, 如果手指已离开触摸显示单元, 则手指离开时所对应的触摸点即为终止位置, 在另一实施例中, 还可以检 测用户是否停止滑动, 如果是的话, 则手指停止滑动时对应的触摸点即为 终止位置。
进一步, 在其他实施例中, 当手指在触摸显示单元进行滑动时, 还记 录滑动轨迹上触摸点的位置信息, 例如坐标值, 可以记录所有触摸点的位 置信息, 也可以进行采样, 只记录滑动轨迹上的 M个触摸点的位置信息, 其中 M大于等于 2, 且为整数, 且 M个触摸点的位置信息中包括起始位置 和终止位置。 其中, 具体采样频率根据不同的触摸显示单元而稍有不同, 一般情况下大概是 50-200赫兹之间 ,每一个时间点上包含三维数据: ( X , y, sw ), 其中 x、 y分别是当前触摸点的横坐标和纵坐标, sw则为一个反映压 力的二值信号, 用来标识当前操作体处在落下还是抬起的状态。
接下来, 执行步驟 103 , 计算滑动轨迹的距离, 为了本领域技术人员更 清楚的了解本发明, 下面举具体的实例来具体的说明, 其中电子终端以手 机为例。
请参考图 2, 例如手机 20包括触摸显示单元 200, 此时手机 20处于用 户界面锁定状态, 用户在触摸显示单元上滑动, 形成滑动轨迹 201 , 在本实 施例中, 滑动轨迹 201显示在触摸显示单元 200上。
在本步驟中, 先可以按照上述介绍的方法获取滑动轨迹上的 M个触摸 点的位置信息,然后分别计算 M个触摸点中相邻两个触摸点之间的子距离, 可以获得 M-1个子距离,进一步根据 M-1个子距离,获得滑动轨迹的距离, 例如将所有子距离进行累加即可获得滑动轨迹的距离。
例如, 请参考图 2, 对滑动轨迹 200进行采样, 获得了触摸点 A、 触摸 点 B和触摸点 C的位置信息, 其中, 触摸点 A对应滑动轨迹 200的起始位 置, 触摸点 B对应滑动轨迹 200的终止位置, 触摸点 A的位置信息为(xl , yl ), 触摸点 C的位置信息为 (x2, y2 ), 然后利用公式 Dl=sqrt [ ( x2-xl ) Λ2 + (y2-yl)A2 ]计算触摸点 A和触摸点 C之间的直线距离 D1 , 同理, 计算 出触摸点 C和触摸点 B之间的之间距离 D2, 然后将直线距离 D1和直线距 离 D2相加, 最终得到滑动轨迹 200的轨迹长度, 即距离 202。 由此可见, 对滑动轨迹上采样的触摸点越多, 计算出来的滑动距离就越精确。
在本实施例中, 步驟 103可与步驟 102同时进行, 也可在步驟 102之 后进行, 当在步驟 102之后进行时, 采样也可在需要计算滑动轨迹距离的 时候进行, 即在步驟 102之后进行。
在本实施例中, 是采用对滑动轨迹进行采样, 获取多个触摸点的位置 信息, 然后计算相邻两个触摸点之间的距离, 再将这些距离累加得到滑动 轨迹的距离, 在其他实施例中, 本领域技术人员还可以采用其他方式计算 滑动轨迹的距离, 例如数像素点, 因为触摸显示单元上具有一个像素点阵, 所以可以通过数像素点就可以获得滑动轨迹的距离。
然后, 执行步驟 104, 即根据滑动轨迹的距离和时间, 计算形成滑动轨 迹的速率, 即手指在触摸显示单元上的滑动速率。
再执行步驟 105, 判断滑动速率是否大于或等于预定速率, 该预定速率 用户可根据实际情况进行设置, 如此, 可避免误操作。
如果步驟 105的判断结果为是的话, 就执行步驟 106, 即解除用户界面 锁定状态。
在进一步的实施例中, 如果步驟 105 的判断结果为否的话, 执行步驟 107, 即将计时单元清零, 清除滑动轨迹并保持用户界面锁定状态, 以方便 下次解锁之用。
综上所述, 本发明实施例中通过点击触摸显示单元的任意位置, 然后 随意滑动, 没有位置及方向的限制, 降低了技术复杂度, 方便用户的操作, 用户体验好。
本发明另一实施例还提供了一种解锁装置, 例如用于实现前述实施例 中的解锁方法。 请参考图 3, 图 3为本实施例解锁装置的功能框图。
如图 3所示, 该装置包括: 检测单元 301 , 用于当电子终端处于用户界 面锁定状态时, 检测操作体在触摸显示单元上的操作; 响应单元 302, 用于 响应操作, 在触摸显示单元上形成滑动轨迹, 并记录形成滑动轨迹的时间; 第一计算单元 303, 用于计算滑动轨迹的距离; 第二计算单元 304, 用于基 于距离和时间, 计算形成滑动轨迹的速率; 判断单元 305, 用于判断速率是 否大于或等于预定速率;解除单元 306,用于当速率大于或等于预定速率时, 解除用户界面锁定状态。
其中, 响应单元 302具体包括轨迹形成单元, 用于在触摸显示单元上 形成连续线条, 连续线条具有起始位置和终止位置。
进一步, 响应单元还包括计时单元, 用于在起始位置时开始计时, 在 终止位置时停止计时。
在另一实施例中, 当速率小于预定速率时, 该装置还包括控制单元, 用于控制计时单元清零, 清除滑动轨迹并保持用户界面锁定状态。
在一实施例中, 第一计算单元 303, 还用于获得滑动轨迹上的 M个触 摸点的位置信息, 其中 M大于等于 2, 且为整数, 且 M个触摸点的位置信 息中包括起始位置和终止位置; 还用于基于 M个触摸点的位置信息, 分别 计算 M个触摸点中相邻两个触摸点之间的子距离, 获得 M-1个子距离, 并 基于 M-1个子距离, 获得滑动轨迹的距离。
进一步, 第一计算单元 303,还用于在响应单元 302在触摸显示单元上 形成滑动轨迹时, 对滑动轨迹进行采样, 获得 M个触摸点的位置信息; 或 者
第一计算单元 303 ,还用于在计算滑动轨迹的距离时,对滑动轨迹进行 采样, 获得 M个触摸点的位置信息。
前述第一实施例和第二实施例中的解锁方法中的各种变化方式同样适 用于本实施例的解锁装置, 通过前述对解锁方法的详细描述, 本领域技术 人员可以清楚的知道本实施例中解锁装置的实施方法, 所以为了说明书的 简洁, 在此不再详述。
本发明另一实施例中, 还提供了一种包括上述解锁装置的电子终端, 该电子终端具有触摸显示单元, 该电子终端例如是手机、 平板电脑、 笔记 本电脑和智能电视。
本领域内的技术人员应明白, 本发明的实施例可提供为方法、 系统、 或计算机程序产品。 因此, 本发明可采用完全硬件实施例、 完全软件实施 例、 或结合软件和硬件方面的实施例的形式。 而且, 本发明可采用在一个 或多个其中包含有计算机可用程序代码的计算机可用存储介质 (包括但不 限于磁盘存储器和光学存储器等 )上实施的计算机程序产品的形式。

本发明一实施例利用用户在触摸显示单元上的滑动距离和滑动时间来 计算滑动速率, 当滑动速率大于等于预定的解锁判定速率, 即可解锁, 所 以在用户界面锁定状态时, 只要点击触摸显示单元, 就可以按照任何轨道 进行滑动, 也没有任何目标点的限定, 所以不用在解锁界面上设置预定轨 道以及预定目标, 大大降低了技术复杂度, 也使得操作更为随意, 用户体 验好, 同时, 因为还要判定滑动速率是否达到预定速率值, 才解除用户界 面的锁定状态, 所以可以有效防止误解锁。
进一步, 本发明一实施例中还当滑动速率没有达到预定速率时, 将计 时单元清零, 并清除滑动轨迹, 并保持用户界面锁定状态, 所以当用户下 次解锁时, 计时单元可从零开始计, 然后重新形成滑动轨迹, 重新计算滑 动速率。
显然, 本领域的技术人员可以对本发明进行各种改动和变型而不脱离 本发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权 利要求及其等同技术的范围之内, 则本发明也意图包含这些改动和变型在 内。
