一种使用动作变化模拟按键操作的方法,用于模拟媒体播放 器的播放操作, 该方法包括以下步骤:

本发明通过传感器检测播放器的运动变化, 由处理器对播放 器的不同运动方向, 运动角度, 运动加速度等动作数据进行计算 和判断, 可以模拟实现导航键的单次按键按下 PRESS, 按键释放 RELEASE, 按键按下并保持(PRESS & HOLD ) 等动作, 并将 特定的动作和播放器可以实现的功能对应起来, 如播放 /暂停, 音 量加减, 上一首, 下一首, 这样就使用不同的动作模拟目前普通 播放器需要很多按键才能实现的功能操作。
图 2 是第一实施例中便携式媒体播放器的组成, 包含传感 器 201、 处理器 203、 存储器 204, 其中,
传感器 201, 可以是陀螺仪或加速度传感器或两者的结合, 用于感应人体运动变化的状态和变化的幅度, 包括测量所述媒体 播放器环绕其自身的纵向轴、 横向轴和垂直于纵向轴和横向轴所 在平面的轴的转动的角度、 方向和速度变化等数据, 并把所述测 量结果发送到处理器;
处理器 203, 负责播放器的运行控制, 根据所述测量结果和 所述对应关系执行相应的按键操作 ,也可以对所述数据进行转换、 计算和判断后, 根据判断结果与相应的按键功能对应且执行至少 一个相关的功能, 包括: 处理并判断不同动作, 使用特定的动作 模拟执行按键按下, 按键释放, 释放后再按下, 以及按下并保持、 向上、 向下、 向左和向右等;
存储器 204,用于存放媒体播放器运行程序及其他数据资料, 包括阈值角度、 阔值时间, 所述测量结果和方向与各个按键之间 的对应关系,以及处理器的判断结果与相应按键功能的对应关系, 并根据处理器的读取请求向其发送所述数据;
阈值角度, 是在程序中设定的一个角度, 在不同方向上的阈 值角度可以设定为不同; 阈值时间, 是在程序中设定的一个时间 数值。
在第二实施例中,上述便携式媒体播放器还可以包括至少如 下之一: 模拟数字转换器 (A/D ) 202、 显示器 205、 一个或多个 传感器有效开关按键 206, 各个部分与第一实施例中各部分的连 接关系如图 3所示, 其中,
模拟数字转换器 202,用于在传感器 201输出模拟电信号时, 将其转换为数字信号, 并将所述数字信号传输给处理器 203; 显示器 205, 是播放器的显示屏幕, 用于显示所述处理器的 处理结果;
当媒体播放器用于看电子书时,可以模拟执行向上翻页和向 下翻页功能, 以及放大缩小等功能, 显示器可以相应显示上述操 作。
传感器有效开关按键 206, 用于开启和关闭传感器, 并且传 感器有效开关按键还可以用于控制播放器的不同功能操作。
传感器有效开关按键 206 (actuator)可以是按钮 (button), 拨 动开关 (switch), 触摸传感器 (touch sensor), 触摸键 (Touch Key), 或触摸板 (Touch Panel)或红外感应 SENSOR等类型的按键。如图 4所示, 播放器中的传感器有效开关按键 401, 402, 403, 404可 以被放置在播放器各角上, 各侧边, 下表面, 上表面等任意位置。 播放器中的传感器有效开关按键 206也可以是 Touch Panel中的 某一块区域或任意区域 405。 当播放器使用 Touch Panel时, 可 以定义 Touch Panel的不同区域代表不同传感器有效开关按键, 当按下 Touch Panel的不同区域时, 播放器的向左, 向右, 向上, 向下等方向的动作操作也可以分别定义为不同功能。
当按下传感器有效开关按键时(此开关也有可能是一个档位 拨动开关, 即拨到 ON时就启动传感器, OFF时就关闭) , 播放 器进行特定的动作可以模拟实现不同功能的操作 (如播放, 音量 加减, 上一首, 下一首等) 。 当放开传感器有效按键开关 (或拨 动到 OFF档位)时, 播放器进行特定的动作均无效, 因为传感器 未打开无法检测动作信号。 传感器有效开关也可以防止误操作, 即当该有效开关未开启时, 对其进行的操作均无效。
传感器有效开关按键 206用于与特定的功能相对应, 即按下 不同的传感器有效开关时, 播放器的向左, 向右, 向上, 向下等 方向的动作操作可以分别定义为不同功能。 比如, 按键 1可以用 于控制音量的大小, 按键 2可以用于控制放大缩小, 按键 3可以 用于控制播放或返回等, 当然, 所述按键与功能的对应关系不限 于此。 举例说明: 当在播放音乐时, 按下某一传感器有效开关键 时, 向上和向下转动可以切换上一首和下一首音乐。 当按下另一 传感器有效开关键时, 向上和向下转动可以增大或减小音量。 也 就是通过使用不同的传感器有效开关键可以使同样向上、 向下、 向左、 向右的转动, 分别代表不同功能的操作, 使四个方向的动 作复用进行更多功能操作。
还有, 当播放器要求的功能复杂时, 通过多个传感器有效开 关的组合实现不同的功能。 比如, 在选定某个音乐文件后, 向上 和向下转动并保持代表相应导航键操作的长按, 可以实现播放音 乐的快进, 快退; 向左和向右转动并保持, 可以暂停和播放正在 播出的音乐。
另外,也可以根据实际不同的应用功能情况选择是否该传感 器有效开关按键的控制功能一直有效。 例如当播放器中有内置游 戏功能时, 为了方便用户玩游戏时快速操作, 降低操作的复杂度, 此时不需开启传感器有效开关, 加速度传感器可直接响应用户的 动作, 且数据有效。
在第三实施例中, 所述处理器用于处理并判断不同动作, 使 用特定的动作模拟实现执行按键按下操作, 如图 5所示, 进一步 包括: 读取模块 2031 , 计算模块 2032, 比较模块 2033, 执行模 块 2034, 设置模块 2035, 其中,
读取模块 2031,用于在传感器启动时以及在运动时,读取传 感器感应到的 X、 Υ、 Ζ轴方向的加速度数据;
计算模块 2032 ,用于根据传感器启动时的加速度数据计算得 到初始位置角度, 以及根据运动加速度数据计算得到绝对转动角 度,并将所述绝对转动角度减去初始位置角度得到相对转动角度; 如图 6说明, 当播放器转动角度为 Θ时, X轴加速度为 ax, Y轴加速度为 ay, Z轴的加速度 az, 以及重力加速度为 1G, Δν 表示所使用的传感器对应 1G重力加速度时输出的相应电压值(从 所使用的传感器的规格书中可以查到) , 则绝对转动角度 Θ的计 算方法为:
θ= arcsinax/ ( lG X AV ) ;
θ= arccosaz/ ( lG X AV ) ; 或
θ= arcsinay/ ( lG X AV ) 。
比较模块 2033, 用于根据运动加速度数值正负得知转动方 向, 由此从所述存 ^f 器中获取该方向上设定的阈值角度, 判断所 述相对转动角度是否大于所述阈值角度, 如果是, 将此时的转动 方向和相对转动角度发送到设置模块和执行模块, 否则, 等待计 算模块重新根据读取的数据计算相对转动角度;
转动方向可以由传感器读取的 ax, az, ay数值的正负进行判 断。 例如: 假设播放器所使用传感器的 X, Y, Z 轴排列方向及 初始位置如图 7中 701所示, 则
当播放器向后转动时(如 702所示), 则 ay输出的数值为正 数;
当播放器向前转动时(如 703所示), 则 ay输出的数值为负 数;
当播放器向左转动时 (如 704所示) , 则 ax输出的数值为 负数;
当播放器向右转动时 (如 705所示) , 则 ax输出的数值为 正数。
Z轴正负可以判断播放器正面朝下还是播放器的反面朝下, 也就是可以判断是正常拿播放器看, 还是躺下时拿播放器看。
执行模块 2034,用于根据所述比较模块的输出结果, 以及读 取所述存储器保存的动作和播放器功能的对应关系, 执行相应的 按下操作并通知显示模块进行相应显示;
设置模块 2035,用于在读取传感器启动时的数据后,保存播 放器初始位置数据, 清除动作有效标志, 清除动作保持标志, 清 除有效时间计时器, 清除初始运动方向; 以及在传感器的动作有 效后, 设置初始运动方向标志以及动作有效标志。
播放器初始位置数据, 是指启动传感器时播放器所处的位 置, 将读取模块读取的传感器 X、 Υ、 Ζ轴方向的输出位置数据, 保存在设置模块。 所述位置数据指在手持播放器时, 静态重力加 速度在 X、 Υ、 Ζ轴方向的重力加速度分量值;
初始运动方向标志,这个标记用来记录此次有效的动作相对 于播放器初始位置的运动方向;
动作有效标志, 当播放器相对初始位置有运动变化, 并且此 次的动作变化有效时就设定这个标志, 相当于模拟表示按键的按 下 (PRESS )标志。
在第四实施例中, 所述处理器还用于处理并判断不同动作, 使用特定的动作模拟实现执行按键释放操作, 其中,
所述比较模块 2033还用于在所述相对转动角度有变化, 且 与初始运动方向相反时, 回到初始位置状态后没有继续向相反方 向运动, 或者即使向相反方向运动也没有达到设定的阈值角度, 此时, 模拟实现动作释放操作;
所述执行模块 2034还用于根据所述比较模块的输出结果, 执行释放所述按下按键的操作; 以及
设置模块 2035还用于清除动作有效标志, 清除动作保持标 志, 清除有效时间计时器, 清除初始运动方向。
在第五实施例中, 所述处理器还用于处理并判断不同动作, 使用特定的动作模拟实现执行释放后再按下的操作, 其中, 所述比较模块 2033还用于在所述相对转动角度有变化, 且 其运动方向与初始运动方向既不相同也不相反时, 判断相对转动 角度是否大于该方向上设定的阈值角度, 如果是, 则新输入的动 作操作有效, 即模拟了释放原按键, 又按下新按键的操作; 所述 比较模块还用于在所述相对转动角度有变化, 且其运动方向与初 始运动方向相反时, 回到初始位置后继续向相反方向运动, 直到 所述相对转动角度大于该方向上的阈值角度, 则模拟了释放原键 按下新键的操作;
所述执行模块 2034还用于执行释放原按键, 按下新按键的 操作;
所述设置模块 2035还用于清除动作有效标志, 清除动作保 持标志, 清除有效时间计时器, 清除初始运动方向, 以及设定新 的初始运动方向,设定动作有效标志和重新开启有效时间计时器。
在第六实施例中, 如图 8所示, 所述处理器还用于处理并判 断不同动作, 使用特定的动作模拟实现执行按键按下并保持的操 作,进一步包括: 计时模块 2036,用于记录有效动作的保持时间; 其中,
所述比较模块 2033还用于在所述相对转动角度没有变化; 或者在所述相对转动角度有变化, 且其运动方向与初始运动方向 相反时, 播放器还没有运动到初始位置状态; 或者在所述相对转 动角度有变化, 且其运动方向与初始运动方向相同时; 或者在所 述相对转动角度有变化, 且其运动方向与初始运动方向既不相反 也不相同时, 但其转动角度小于设定的阈值角度; 在上述四种情 况下, 判断计时模块 2036是否到达设定的阈值时间, 如果是, 则 动作保持有效, 即模拟按键按下并保持, 否则, 认为所述操作无 效, 由所述读取模块 2031重新提取传感器运动状态数据;
所述执行模块 2034还用于在按下并保持的动作有效时, 执 行按下并保持操作;以及所述设置模块 2035设定动作保持有效标 志。
上述第三至第六实施例中, 所述计算模块 2032还用于在运 动方向是多个方向的叠加时,分别计算多个方向的相对运动角度; 以及
所述比较模块 2033还用于将所述相对转动角度大于阈值角 度的方向作为新的运动方向。 当有多个方向的运动角度都大于阈 值角度时, 则按照如下原则处理: 最大转动角度的方向优先有效, 如果各方向的转动角度相同时按照向左, 向右, 向后, 向前的优 先顺序进行处理, 并通知执行模块 2034和设置模块 2035。
在第六实施例的基础上, 即模拟实现按键按下并保持的操作 时, 所述处理器还用于处理并判断不同动作, 并把这些特定的动 作和播放器可以实现的功能对应起来。 其中, 对应执行什么功能 是根据目前播放器所在的功能模式有关而设定的。 即可以使用特 定的动作模拟实现上下翻页, 放大缩小, 音量增减, 返回播放等 操作
所述读取模块还用于在所述设置模块的动作保持标志置位 时, 读取此时的运动加速度、 位移数据和 /或方向数据, 将所述数 据发送到所述执行模块,或者将经过所述计算模块和 /或所述比较 模块处理后的数据发送到所述执行模块;
所述执行模块还用于根据所述数据或数据组合,执行与其对 应的功能操作, 所述功能操作至少包括如下之一: 放大缩小, 音 量增减, 上下翻页, 播放停止, 快进快退, 上 (前) /下 (后) / 左 /右四个方向的模拟导航按键操作。
例如, 当播放器在浏览图片的模式界面下时, 可以定义垂直 向下的运动动作代表显示的图片放大(或缩小) 功能, 垂直向上 的运动动作可以代表显示的图片缩小 (或放大) 功能。 下面以查 看图片或文字操作为例, 说明放大缩小的执行过程。
在使用播放器查看图片或文字内容时,如果沿垂直播放器平 面向下移动可以模拟 SCALE DOWN显示的图片和文字,相应地, 也可以沿垂直播放器平面向上移动模拟 SCALE UP显示的图片 和文字, 并且放大和缩小的比例与播放器移动的加速度或位移距 离成正比。 当沿垂直播放器平面向上或向下移动时, Z轴上的动 态加速度和运动方向可以从加速度传感器中读出。 并经计算模块 处理后, 由比较模块和设定的加速度数值进行比较, 不同的加速 度大小代表不同的放大或缩小比例, 运动方向对应放大或缩小功 能, 这样该加速度的大小与放大或缩小的比例对应起来, 就可对 查看的图片或文字内容进行按比例放大或缩小, 也可以根据传感 器输出的加速度的方向对应放大或缩小的功能。
另夕卜,当播放器在看电子书模式界面下时,可以定义向左(或 向上)的运动动作执行向上翻一页的功能, 和定义向右(或向下) 的运动动作执行向下翻一页的功能。 而向左、 向右、 向上、 向下 的动作有效的判断方法与图 11中流程图说明的判断方法相同。
同理, 也可以模拟播放, 暂停, 回退等操作。 如图 9所示, 以图 901为基准, 也可以沿垂直播放器平面的线为轴顺时针(如 图 903 )或逆时针(如图 902 )转动一定角度模拟实现其它按键的 功能操作。 顺时针或逆时针转动可以模拟两个按键的动作, 具体 对应的功能不是固定的, 可以依不同播放器的设计而定义为不同 功能。 例如, 模拟的两个按键可以定义为代表返回键和播放键的 功能, 也可以代表音量增加和音量减小功能。
其中,顺时针或逆时针的判断方法,可以按照下述方式进行, 当重力加速度在 X, Y, Z轴上的分量与 X, Y, Z轴方向一致时 输出的加速度数值就是正值, 与 X, Y, Z 轴方向相反时输出的 加速度数值就是负值。当播放器沿播放器顺时针或逆时针转动时, 如果此时 Z轴的加速度不变化或 Z轴相对于设定的初始位置状态 的转动角度小于阈值角度, 而 X, Y轴有动态的加速度变化, 可 以根据动态加速度的正负值判断转动的方向是顺时针或逆时针。
本发明提出的使用加速度传感器 (或与陀螺仪结合的传感 器) 测量播放器的倾斜, 转动的方向, 角度, 速度变化等动作数 据来模拟按键按下 PRESS,释放 RELEASE和按下并保持 PRESS & HOLD, 并把这些特定的动作和播放器可以实现的功能对应起 来, 从而可以完全不用在机器表面摆放按键或摆放少量的辅助按 键就可以模拟完成媒体播放器的按键操作功能。
相应地, 基于上述便携式媒体播放器, 本发明提出了一种使 用动作变化作为输入模拟按键操作的方法, 该方法可以应用于使 用动作变化作为输入模拟按键操作的系统中,所述系统可以包括: 传感器, 处理器和存储器, 也可以进一步包括模数转换器、 显示 器和传感器有效按键开关等。 该方法包括以下步骤:
测量所述媒体播放器环绕其自身的纵向轴、横向轴和垂直于 纵向轴和横向轴所在平面的轴的转动的角度和方向; 以及
根据预设的所述转动角度和方向与各个操作模式之间的对 应关系, 执行至少一个相关的操作。
在第七实施例中, 所述方法模拟按键按下的操作, 如图 10 所示, 包括以下步骤:
步骤 301,当传感器开始工作时,将感应到的加速度数据 X0、 Υ0、 Ζ。传送给处理器;
如果传感器将感应到的加速度数据转换为电信号,则经模拟 数字转换器转换为数字信号 Χ。、 Υ。、 后传输给处理器。 当所述 使用动作变化作为输入模拟按键操作的系统中还包括有效按键开 关时, 启动播放器上的传感器有效开关按键 206, 使传感器进入 正常工作状态。 步骤 302, 由处理器将数据设定为初始位置状态数据, 并根 据角度计算公式计算出此时的转动角度 θ0;
步骤 303, 清除动作有效标志、 清除动作保持标志、 清除有 效时间计时器、 清除初始运动方向标志, 这些标志是在软件程序 中定义的用来表示相关动作状态的;
步骤 304, 当传感器感应到运动变化的加速度数据 Υι, 时, 将所述加速度数据传送给处理器;
步骤 305, 由处理器根据读取的加速度 ^计算相对 转动角度 并根据加速度数值的正负得知转动方向;
根据角度计算公式计算得到绝对转动角度 θ 然后减去设定 的初始位置状态数据 θ。, 得到播放器相对初始位置的相对转动角 度 ΔΘ
步驟 306, 判断所述相对转动角度 是否大于该方向上设 定的阈值角度, 如果是, 执行步骤 307, 否则, 跳转到步驟 304;
步骤 307, 此次动作操作有效, 即模拟按键按下操作; 步驟 308, 设定该动作方向为初始运动方向, 设定动作有效 标志, 并开启有效时间计时器。
在第八实施例中,使用动作变化作为输入模拟按键操作的方 法, 其中, 使用特定的动作模拟实现按键释放的操作, 释放后再 按下的操作, 以及按键按下并保持的操作,在第七实施例基础上, 如图 11所示, 还包括以下步骤:
步驟 309, 再次由传感器将感应到的 X、 Y、 Ζ轴方向的运 动加速度数据 Χ2、 Υ2、 Ζ2传送给处理器;
步骤 310, 根据所述加速度数据 Χ2、 Υ2、 Ζ2计算相对转动角 度 Δθ2, 并根据加速度数值的正负得知转动方向;
步骤 311, 判断相对转动角度是否发生变化, 即判断 Δθ2与 是否不一致, 如果是, 执行步骤 312, 否则, 执行步骤 317; 步骤 312, 判断新的运动方向与初始运动方向是否相反, 如 果是, 执行步骤 315, 否则, 执行步骤 313;
在处理器的内部存储器中保存的数据可以有:播放器初始位 置(步骤 302中保存的初始位置数据 X。、 Y。、 Ζο ) ; 动作有效标 志; 动作保持标志; 初始运动方向标志; 相对初始位置的转动方 向和转动角度(步骤 305, 步骤 310 ) 。
步骤 313, 判断新的动作方向与设定的初始运动方向是否相 同, 如果是, 执行步骤 317, 否则, 执行步骤 314;
步驟 314,判断转动角度是否大于该方向上设定的阈值角度, 如果是, 执行步骤 319, 否则, 执行步骤 317;
该步骤中包括两种情况,一种是新的运动方向与初始设定的 运动方向既不同也不相反, 另一种是运动方向为回到初始位置后 继续向相反方向运动, 此时, 均可以通过该步驟来判断新运动方 向是否有效。 对于新的运动方向与初始设定的运动方向既不同也 不相反时,假设初始运动方向为图 7中 703所表示的向前运动时, 则步骤 312所判断的相反运动方向为 702所表示的向后运动, 如 果新的运动方向即不是 703的向前也不是 702的向后,则是指 704 和 705中所表示的向左或向右运动方向。
当有同时多个方向的倾斜或转动时,分别计算多个方向的相 对转动角度, 将所述相对转动角度大于阈^:角度的方向作为新的 运动方向。 当有多个方向的运动角度都大于阔值角度时, 则按照 如下原则处理: 最大转动角度的方向优先有效, 如果各方向的转 动角度相同时按照向左, 向右, 向后, 向前的优先顺序进行处理。
步骤 315, 判断是否到达初始位置状态, 如果是, 执行步骤 316, 否则, 执行步骤 317;
步骤 316, 判断是否继续向相反方向运动, 如果是, 执行步 骤 322; 否则, 执行步骤 323; 步骤 317, 判断是否到达设定的阔值时间, 如果是, 执行步 骤 318; 否则, 结束;
在该步骤中,读取有效时间计时器的数值并与设定的阈值时 间比较, 如果大于阈值时间, 则执行步骤 318, 表示之前动作保 持有效启动, 即模拟按键按下并保持。 如果读取的时间小于阈值 时间, 则此次操作结束, 可以执行步驟 309继续操作。
步骤 318, 进入动作保持状态, 设定动作保持有效标志, 即 模拟实现按键按下并保持(PRESS&HOLD ) , 结束;
当不同方向的动作操作和某些播放器的功能连接起来的时 候,还可以通过显示器显示当前播放器的状态和动作操作的效果。 另外, 也可以将传感器有效开关按键与播放器功能对应, 即当所 述开关按键有效时, 其对应的功能才有效。 在执行完该步骤后, 可以继续执行步骤 309继续操作。
步骤 319, 表示新运动方向的转动角度大于阔值角度, 即表 示新的运动有效。 以上即模拟实现原来方向的按键释放 ( RELEASE ) , 同时新的方向的按键按下 (PRESS ) , 执行步 骤 320;
假设初始播放器的运动方向向前,如果新的运动方向向右或 向左, 且转动角度大于阔值角度, 则向左或向右的运动有效, 即 模拟向前的按键释放, 并按下向左或向右的按键。
步骤 320, 清除动作有效标志、 清除动作保持标志、 清除有 效时间计时器、 清除初始运动方向标志;
步骤 321,新方向的动作操作有效,设定新的初始运动方向, 设定动作有效标志, 并开启有效时间计时器, 结束; 然后, 可以 跳转到 309继续执行;
步骤 322, 判断相对转动角度是否大于设定的阈值角度, 如 果是, 执行步骤 319, 否则, 执行步骤 323; 步骤 323, 模拟动作释放操作, 即释放操作有效, 结束, 此 时, 也可以继续执行步骤 303。
本方法可以通过播放器向前、 向后、 向左、 向右倾斜或转动 动作模拟实现四个方向的按键按下 PRESS,按鍵释放 RELEASE, 按键按下并保持 PRESS & HOLD、 向上、 向下、 向左和向右等 功能, 即可以模拟图 1中导航键的四个方向的操作。
