下面结合附图和实施例对本发明做进一步的描述。 基于触摸屏的数字输入编辑组件的第一实施例 图 1示出了本发明的基于触摸屏的数字输入编辑组件的第一实施例的原 理。 请参见图 1, 本实施例的数字输入编辑组件包括数字输出单元 11、 数字输 入单元 12以及功能输入单元 13。 图 2示出了本实施例在触摸屏上显示的用户 界面。
数字输出单元 11在触摸屏的数字显示区域 11a中显示用户输入的数字, 而且数字显示区域 1 1a中也提供对数字的编辑操作。 这种编辑操作既可以是点 击操作, 也可以是滑动操作 (拖动数字的操作) 。
数字输入单元 12在触摸屏的数字响应区域 12a中显示 0~9这十个数字以 供用户进行按键式以及滑动式的操作。 较佳的, 0~9这十个数字在触摸屏上所 示的呈轮盘状的数字响应区域 12a是依序以环形顺序排列的, 这样便于数字输 入的滑动操作。轮盘上的数字可以通过用户的操作输出到数字显示区域 11a上, 例如可以通过点击轮盘上的数字将相应数字输出到数字显示区域 11a上, 通过 滑动经过轮盘上的数字将相应的数字输出到数字显示区域 1 1a上。
功能输入单元 13在触摸屏的功能响应区域中显示对应的功能符号以供用 户进行操作。 功能响应区域设计成按钮响应区域, 按钮响应区域分为角按钮响 应区 13a (称为 Corner Buttons ) 和中央按钮响应区 13b (称为 Central Buttons Area) , 其中角按钮响应区 13a位于轮盘状的数字响应区域 12a的外侧的四个 角上, 中央按钮响应区 13b位于轮盘状的数字响应区域 12a的内部区域。
在本实施例中, 功能输入单元 13是运算符号输入单元, 其中在角按钮响 应区 13a中分别设置加、 减、 乘、 除的运算符号按钮, 在中央按钮响应区 13b 上设置等号、 小数点的运算符号按钮, 这些按钮提供给用户做按键式的操作。
当然, 角按钮响应区 13a和中央按钮响应区 13b都可以是自定义的区域, 根据需求不同可以任意变化, 如图 5所示, 例如如果整个用户界面是手机拨号 盘, 则角按钮响应区 13a可以是联系人、 接听挂断等不同功能的按钮, 而中央 按钮响应区 13b可以是接听挂断等, 根据具体应用情况可相应自由变动。 基于触摸屏的数字输入编辑组件的第二实施例 图 3示出了本发明的基于触摸屏的数字输入编辑组件的第二实施例的原 理。 请参见图 3, 本实施例的数字输入编辑组件包括数字输出单元 21、 数字输 入单元 22、 功能输入单元 23以及数阶显示单元 24。 图 4示出了本实施例在触 摸屏上显示的用户界面。
数字输出单元 21在触摸屏的数字显示区域 21a (称为 G-Number) 中显示 用户输入的数字, 而且数字显示区域 21a中也提供对数字的编辑操作。 这种编 辑操作既可以是点击操作, 也可以是滑动操作 (拖动数字的操作) 。
数字输入单元 22在触摸屏的数字响应区域 22a中显示 0~9这十个数字以 供用户进行按键式以及滑动式的操作。 较佳的, 0~9这十个数字在触摸屏上所 示的呈轮盘状的数字响应区域 22a是依序以环形顺序排列的, 这样便于数字输 入的滑动操作。 轮盘 (称为 G-Wheel) 上的数字可以通过用户的操作输入到数 字显示区域 21a上, 例如可以通过点击轮盘上的数字将相应数字输出到数字显 示区域 21a上, 通过滑动经过轮盘上的数字将相应的数字输出到数字显示区域 21a上。
功能输入单元 23在触摸屏的功能响应区域中显示对应的功能符号以供用 户进行操作。 功能响应区域设计成按钮响应区域, 按钮响应区域分为角按钮响 应区 23a和中央按钮响应区 23b, 其中角按钮响应区 23a位于轮盘状的数字响 应区域 22a的外侧的四个角上, 中央按钮响应区 23b位于轮盘状的数字响应区 域 22a的内部区域。
在本实施例中, 功能输入单元 23是运算符号输入单元, 其中在角按钮响 应区 23a中分别设置加、 减、 乘、 除的运算符号按钮, 在中央按钮响应区 23b 上设置等号、 小数点的运算符号按钮, 这些按钮提供给用户做按键式的操作。
当然, 角按钮响应区 23a和中央按钮响应区 23b都可以是自定义的区域, 根据需求不同可以任意变化, 如图 5所示, 例如如果整个用户界面是手机拨号 盘, 则角按钮响应区 23a可以是联系人、 接听挂断等不同功能的按钮, 而中央 按钮响应区 23b可以是接听挂断等, 根据具体应用情况可相应自由变动。
在本实施例中, 数阶显示单元 24用于在触摸屏的数阶显示区域 24a (称为 G-Marker) 中表示数字显示区域 21a中的数字的数阶, 其中数阶显示区域 24a 位于数字显示区域 21a的正上方或者正下方 (在本实施例中是正下方) 并通过 一分隔符号组 (在本实施例中为倒三角符号) 来划分对应的数字, 在数阶显示 区域 24a的最前方为一主提示符, 以显示当前数字的数阶大小。
传统的数量级标记通过每隔 10的三次方插入一个逗号来产生提示, 如图 27A所示, 这样人们不需要去数整个数字串到底有多少位就能了解这个数字在 多大的数量级上。 如图 27A所示, 一看便知是 1M ( Million) 。 但是传统的数 量级标记法在现代智能设备上遇到了新的挑战。 因为智能设备 (特别是移动设 备) 屏幕的宽度有限, 所以逗号占用了非常有限的横向显示空间, 使得能够表 示的数字位数减少了。
在本发明中, 可以采用倒三角符号来代替逗号, 放在数字串的下方, 不占 用横向显示空间, 以此来解决传统数量级标记法遇到的问题, 如图 27B所示, 数量 (数阶) 标记由两部分组成: 主提示符和分隔符号组。
传统的标记法并没有明确的标识出数字的数量级, 如果数字特别大的时 候, 用户不得不去数逗号的数目, 以此来算出数量级。 比如下面这个数: 54,554,545,064,565,664,455,434,用户先要数出逗号的数目,这里逗号数目为 7, 这个数的数量级为 7 X 3+1=22及 10的 22次方。 主提示符的作用是利用智能设 备的计算能力, 让设备代替人去 "数逗号" , 比如上边的数字的主提示符为 " G22 " , 这样用户不需要去数逗号直接就知道这个数的数量级了。 主提示符 的格式为: (1 ) 有小数点的情况: Gn,m, (2 ) 没有小数点的情况: Gn。 G表 示这是一个主提示符, n为整数部分的数量级幂的指数, m为小数部分数量级 幂的指数的相反数。 比如 12345678. 0012这个数的整数部分是 12345678, 数量 级幂为 10 Λ 7 , 指数为 7, 小数部分为 0. 0012, 数量级幂为 10 Λ -4 , 所以这个 数的主提示符为 G7. 4, 另外没有小数部分的数, 比如 123456789这个数相应的 主提示符就是 G8。 分隔符号 (即倒三角符号) 是代替逗号, 并且不占用横向数 字显示空间, 而是放在数字串下边的数字与数字之间, 其主要作用就是节省横 向显示空间。 另外还有和传统标记法不同的是, 传统标记法的分隔符只分隔整 数部分, 而不分隔小数部分, 但是本发明的分隔符在小数部分也会分隔, 如图 27C所示。 基于触摸屏的数字输入编辑方法的实施例 本发明的基于触摸屏的数字输入编辑方法是根据上述的基于触摸屏的数 字输入编辑组件来实现的。 由于基于触摸屏的数字输入编辑组件在前述内容已 经详细描述, 在此不再赘述。
本实施例的方法如图 6所示, 详述如下。
步骤 S60: 对用户的手势进行识别, 若是单击手势则直接进行单个数字的 输入, 若是滑动手势则进入后续的步骤。
步骤 S61 : 对用户在触摸屏上的滑动轨迹进行采样, 以获得当前采样点的 坐标位置, 并保存上一个采样点的坐标位置。 采样频率一般为屏幕刷新率, 例 如 60帧每秒。
步骤 S62: 根据采样到的坐标位置获得用户当前输入位置所在区域, 是位 于背景区域、 数字响应区域或是功能响应区域。
在本实施例中, 触摸屏的功能响应区域是按钮响应区域, 按钮响应区域分 为角按钮响应区和中央按钮响应区, 其中角按钮响应区位于轮盘状的数字响应 区域的外侧的四个角上, 中央按钮响应区位于轮盘状的数字响应区域的内部区 域, 功能输入单元是运算符号输入单元, 其中在角按钮响应区上分别设置加、 减、 乘、 除的运算符号, 在中央按钮响应区上设置等号、 小数点的运算符号, 按钮响应区域不接受滑动手势只接受单击手势的操作。
利用遮罩数组来实现对输入位置所在区域的判断, 遮罩数组是一个二维数 组, 这个数组中的每个元素都与触摸屏上的一个像素对应。 可以把这个二维数 组看成一幅二维图, 把不同的数值看成是不同的颜色, 就可以在这幅图 (数字 阵列) 上用不同的颜色 (不同的数值) 作图。 先将整个数组清零, 给 0~9十个 数字编号为 10~19, 然后用编号值在这个二维图上围绕轮盘画 10个圆, 每个圆 都包含一个轮盘上的数字且编号值与轮盘上的数字的值对应, 同理给其他按钮 编号,四个角按钮 A1~A4编号为 21~24,两个中央区按钮 C0~C1编号为 30~31, 然后用编号值作圆包含这些按钮。
在用户界面上,背景区域是数值为零的区域,数字响应区域是数值为 10 19 的区域, 按钮响应区域是数值为 21~24及 30~31的区域。
根据输入位置的坐标值 , y) 从遮罩数组中取值 V, 以此来判断用户当 前输入位置所在区域。如果 V属于区间 [10~19]中, 则说明用户当前输入位置在 数字响应区内, 比如 V = l l, 则说明用户当前输入位置在轮盘上的数字 " 1 " 上。 同理, 如果 V属于区间 [21~24], 比如 V = 22则说明用户当前的输入位置 在右上角的角按钮上。如果 V属于区间 [30~31], 则说明用户当前输入位置在中 央按钮区的某一个按钮之上。
步骤 S63 : 基于上一个采样点和当前采样点的坐标位置判断用户轨迹的方 式: 若上一个采样点在数字响应区域外且当前采样点在数字响应区域内, 则判 断为用户从数字响应区域外滑动进入数字响应区域内, 若上一个采样点和当前 采样点均在数字响应区域内, 则判断为用户在数字响应区域内滑动, 若上一个 采样点在数字响应区域内且当前采样点在数字响应区域外, 则判断为用户从数 字响应区域内滑动到数字响应区域外。
步骤 S64: 基于用户轨迹的方式判断是否触发一次数字输入, 且输入的值 是由预设的当前输入位置所在区域和数值的对应关系确定。
在触发一次数字输入的判断中, 若从数字响应区域外滑动进入数字响应区 域内则触发一次数字输入, 若在数字响应区域内滑动且用户输入的初始位置在 数字响应区域内则触发一次数字输入。
如果上一个采样点在数字响应区外 (V在区间 [10~19]之外) , 并且当前采 样点在数字响应区内 (V属于区间 [10~19] ) , 则判断为用户从数字响应区外滑 动进入了数字响应区内, 这样就触发一次数字输入 (输入的值等于编号值对应 的数值, 比如 V = 15对应的数值是 5, 即在屏幕上输入 5 ) 。 当用户在数字响 应区内滑动 (有一个例外, 如果用户输入的初始位置就在数字响应区内, 则触 发一次输入) 或从数字响应区内滑动到数字响应区外都不触发数字输入。
这样当用户连续的在轮盘上或轮盘间滑动时, 每经过一个数字响应区, 都 会输入一个与该数字响应区对应的数到屏幕上, 从而实现了通过滑动进行连续 的数字输入。
此外, 当用户在滑动时, 有可能滑动轨迹会经过按钮响应区, 但此时不触 发按钮功能, 以此来保证连续输入数字不被打断。 按钮只响应 "单击" 这种手 势, 程序会实时的侦测用户的手势。 数字响应区除了响应 "滑动手势" , 同时 也响应 "单击" 手势, 也就是说, 用户也可以通过单击数字响应区来进行数字 输入。 基于触摸屏的数字输入编辑系统的实施例 本发明的基于触摸屏的数字输入编辑系统是根据上述的基于触摸屏的数 字输入编辑组件来实现的。 由于基于触摸屏的数字输入编辑组件在前述内容已 经详细描述, 在此不再赘述。
如图 7所示, 本实施例的数字输入编辑系统包括: 手势识别装置 71、 采样 位置获取装置 72、 区域判断装置 73、轨迹方式判断装置 74、输入触发装置 75。
手势识别装置 71对用户的手势进行识别, 若是单击手势则直接进行单个 数字的输入, 若是滑动手势则进入后续的装置进行处理。
采样位置获取装置 72对用户在触摸屏上的滑动轨迹进行采样, 以获得当 前采样点的坐标位置, 并保存上一个采样点的坐标位置。 采样频率一般为屏幕 刷新率, 例如 60帧每秒。
区域判断装置 73根据采样到的坐标位置获得用户当前输入位置所在区域, 是位于背景区域、 数字响应区域或是功能响应区域。
触摸屏的功能响应区域是按钮响应区域, 按钮响应区域分为角按钮响应区 和中央按钮响应区, 其中角按钮响应区位于轮盘状的数字响应区域的外侧的四 个角上, 中央按钮响应区位于轮盘状的数字响应区域的内部区域, 功能输入单 元是运算符号输入单元, 其中在角按钮响应区上分别设置加、 减、 乘、 除的运 算符号, 在中央按钮响应区上设置等号、 小数点的运算符号, 按钮响应区域不 接受滑动手势只接受单击手势的操作。
利用遮罩数组来实现对输入位置所在区域的判断, 遮罩数组是一个二维数 组, 这个数组中的每个元素都与触摸屏上的一个像素对应。 可以把这个二维数 组看成一幅二维图, 把不同的数值看成是不同的颜色, 就可以在这幅图 (数字 阵列) 上用不同的颜色 (不同的数值) 作图。 先将整个数组清零, 给 0~9十个 数字编号为 10~19, 然后用编号值在这个二维图上围绕轮盘画 10个圆, 每个圆 都包含一个轮盘上的数字且编号值与轮盘上的数字的值对应, 同理给其他按钮 编号,四个角按钮 A1~A4编号为 21~24,两个中央区按钮 C0~C1编号为 30~31, 然后用编号值作圆包含这些按钮。
在用户界面上,背景区域是数值为零的区域,数字响应区域是数值为 10 19 的区域, 按钮响应区域是数值为 21~24及 30~31的区域。
根据输入位置的坐标值 (x, y) 从遮罩数组中取值 V, 以此来判断用户当 前输入位置所在区域。如果 V属于区间 [10~19]中, 则说明用户当前输入位置在 数字响应区内, 比如 V = l l, 则说明用户当前输入位置在轮盘上的数字 " 1 " 上。 同理, 如果 V属于区间 [21~24], 比如 V = 22则说明用户当前的输入位置 在右上角的角按钮上。如果 V属于区间 [30~31], 则说明用户当前输入位置在中 央按钮区的某一个按钮之上。
轨迹方式判断装置 74基于上一个采样点和当前采样点的坐标位置判断用 户轨迹的方式: 若上一个采样点在数字响应区域外且当前采样点在数字响应区 域内, 则判断为用户从数字响应区域外滑动进入数字响应区域内, 若上一个采 样点和当前采样点均在数字响应区域内, 则判断为用户在数字响应区域内滑 动, 若上一个采样点在数字响应区域内且当前采样点在数字响应区域外, 则判 断为用户从数字响应区域内滑动到数字响应区域外。
输入触发装置 75基于用户轨迹的方式判断是否触发一次数字输入, 且输 入的值是由预设的当前输入位置所在区域和数值的对应关系确定。
在输入触发装置 75的触发一次数字输入的判断中, 若从数字响应区域外 滑动进入数字响应区域内则触发一次数字输入, 若在数字响应区域内滑动且用 户输入的初始位置在数字响应区域内则触发一次数字输入。
如果上一个采样点在数字响应区外 (V在区间 [10~19]之外) , 并且当前采 样点在数字响应区内 (V属于区间 [10~19] ) , 则判断为用户从数字响应区外滑 动进入了数字响应区内, 这样就触发一次数字输入 (输入的值等于编号值对应 的数值, 比如 V = 15对应的数值是 5, 即在屏幕上输入 5 ) 。 当用户在数字响 应区内滑动 (有一个例外, 如果用户输入的初始位置就在数字响应区内, 则触 发一次输入) 或从数字响应区内滑动到数字响应区外都不触发数字输入。
这样当用户连续的在轮盘上或轮盘间滑动时, 每经过一个数字响应区, 都 会输入一个与该数字响应区对应的数到屏幕上, 从而实现了通过滑动进行连续 的数字输入。 此外, 当用户在滑动时, 有可能滑动轨迹会经过按钮响应区, 但此时不触 发按钮功能, 以此来保证连续输入数字不被打断。 按钮只响应 "单击" 这种手 势, 程序会实时的侦测用户的手势。 数字响应区除了响应 "滑动手势" , 同时 也响应 "单击" 手势, 也就是说, 用户也可以通过单击数字响应区来进行数字 输入。 基于触摸屏的数字输入编辑方法的实施例 (整体方案) 图 8示出了本发明的基于触摸屏的数字输入编辑方法的较佳实施例的整体 流程。 请参见图 8, 首先程序启动并进行初始化, 然后检测是否退出程序, 在 程序运行的情况下, 检测是否有用户输入, 若有输入则判断输入的初始位置所 在区域, 是位于如图 2所示的 A区域 (数字显示区域 11a) 还是 B区域 (数字 响应区域 12a、 角按钮响应区 13a、 中央按钮响应区 13b和背景区域的组合) , 若在 A区域则进行 A区域的处理流程,若在 B区域则进行 B区域的处理流程。
A区域 (数字显示区域) 的处理流程 (可单独作为实施例) 图 9接着示出了数字显示区域 11a上的输入和编辑流程。 请参见图 9, 首 先检测用户在数字显示区域 11a中的手势的类型, 是单击类型还是滑动类型。
若为单击类型, 则进一步检査用户输入位置所在的子区域, 如图 10所示, 此时存在三种情况: 用户输入位置位于从最右边对象槽起、 数字和小数点构成 的区域 (为了简化后面简称为 A3 ) ; 用户输入位置位于紧挨 A3左边的一个空 对象槽(或者有负号的对象槽) (为了简化后面简称为 A2) ; 用户输入位置位 于 A2左边的所有空白区域 (为了简化后面简称为 A1 ) 。
对于用户输入位置位于 A1的情况, 归位后直接进行 A区域规格化处理的 步骤。
如图 10B和 10C所示, 对于用户输入位置位于 A2的情况, 首先判断当前 数是否为负值, 若为负值则通过在有负号的 A2区域 (对象槽) 上的单击消除 负号, 若不为负值则通过在空的 A2区域 (对象槽) 上单击的方式生成负号。 最后归位后直接进入 A区域规格化处理的步骤。
如图 11A-11F所示, 对于用户输入位置位于 A3的情况, 首先判断对象槽 的状态, 是处于如图 11A所示的普通状态还是图 11B所示的编辑状态。 此外, 还有一种如图 11C所示的初始状态, 对象槽组中只有最右端的对象槽中有一个 唯一的对象 " 0" , 且其处于非焦点状态。 当对象槽组处于普通状态时, 如图 11D所示, 通过单击对象槽 Sl, 使得对象 " 3 " 成为编辑焦点, 对象槽组处于 编辑状态。 当对象槽处于编辑状态时, 进一步判断用户输入位置是否在编辑焦 点对象之上。 若用户输入位置位于编辑焦点对象之上, 则取消编辑, 如图 11E 所示, 此时对象槽组处于编辑状态, 编辑焦点为 S1中的对象 " 3 " , 用户单击 对象槽 Sl, 对象 " 3 " 编辑焦点被取消, 对象槽组回归普通状态。 若用户输入 位置位于编辑焦点对象之外, 此时需要改变编辑焦点, 如图 11F所示, 对象槽 组处于编辑状态, 编辑焦点为 S1中的对象" 3 ", 用户单击对象槽 S2, 对象" 2" 被设置为新焦点, 对象 " 3 " 的编辑焦点被取消。 最后归位后进入 A区域规格 化处理的步骤。
上述为单击手势中的处理流程, 以下为滑动手势的处理流程。
首先检测用户输入位置所在子区域, 若为 A1区域则重复检测这一步骤, 若为 A2区域则进一步检测是向左滑动还是向右滑动。 若向左滑动则返回检测 所在子区域的步骤, 若向右滑动则进行清零处理, 并在清零处理之后返回检测 滑动方向的步骤, 在滑动结束后归位, 然后进入 A区域规格化处理的步骤。
清零处理请参见图 12A~12C的示意。 清零处理实质上是一种消除处理, 图中的浮动组由深色框表明, 浮动组是一串连续字符, 作为一个整体随着用户 的滑动进行移动。 浮动焦点对象是指浮动组中处于用户输入位置上的对象, 在 消除处理时, 处在用户输入位置上的对象成为浮动焦点对象, 浮动焦点对象及 其左边连续的对象组成浮动组。 如图 12A所示, 用户从 A1开始向右滑动, 当 滑动到 A2时, 产生一个 "虚零" , 并且 "虚零" 单独成为浮动组, 向右进行 消除。用户一直向右滑动到最右端, 待用户输入结束完成清零。如图 12B所示, 用户从 A2开始向右滑动, A2立刻产生一个 "虚零" , 并且 "虚零"单独成为 浮动组, 向右进行消除。 用户一直向右滑动到最右端, 待用户输入结束后完成 清零。 如图 12C所示, A2处有负号, 设置负号为浮动焦点, 并单独成为浮动 组, 向右进行消除。用户一直向右滑动到最右端, 待用户输入结束后完成清零。 用户输入位置位于 A3子区域的情况下, 首先检测当前数是否为零, 若为 零则进行初始零拖动处理的步骤, 处理后归位, 然后进入 A区域规格化处理的 步骤。 初始零拖动处理的详细步骤请参见图 13, 首先生成零浮动子串, 然后判 断当前的零是否越过左边对象槽。 若当前的零越过了左边对象槽, 则在零的右 边生成小数点, 接着组成零点浮动子串。 之后, 检测滑动方向是向左滑动还是 向右滑动。 若向左滑动, 则进行生成处理; 若向右滑动, 则将零点浮动子串变 成零浮动子串, 然后做消除处理。
具体而言, 请参见图 14A, 示出了初始零向左拖动的示例。 首先零成为浮 动焦点对象, 当跨越了左边的对象槽后在零的右边生成小数点, 由零和小数点 组成浮动组, 之后检测浮动组是向左滑动还是向右滑动, 若向左滑动则在浮动 组右边生成零 (生成处理) , 若向右滑动则如图 14B所示, 从零点浮动子串变 成了零浮动子串 (浮动组中只包含 " 0" , 小数点被排除在外) , 如果继续向 右滑动, 则变成了普通的清零操作。
用户输入位置位于 A3子区域的情况下, 且当前数不为零时, 检测对象类 型, 是数字还是小数点。 若对象为数字则进行数字拖动处理, 然后归位和做 A 区域规格化处理, 若对象为小数点则进行小数点拖动处理, 然后归位和做 A区 域规格化处理。
数字拖动处理的细化步骤如图 15所示, 首先生成数字浮动组, 然后检测 滑动方向是向左滑动还是向右滑动。 若为向左滑动则做生成处理, 若为向右滑 动则做消除处理。 生成处理和消除处理在之前的内容中也提到过, 为了进一步 加深理解, 特别结合附图解释生成处理和消除处理。
如图 16所示, 消除处理的具体过程如下, 图中的 Si代表对象槽(SLOT), 浮动组由深色框表明。 用户初始输入位置位于对象 S2的侦测范围内, 用户开 始向右滑动。 对象" 3 "成为浮动焦点对象, 并和它左边的两个对象 " 1 "、 " 2" 组成浮动组。 浮动组随着用户的滑动向右移动, 当浮动组右端 "跨越" 了右边 的一个对象槽时, 该对象槽原本的对象 "4" 被消除。
如图 17所示, 生成处理的具体过程如下所述, 用户初始输入位置位于 S1 的侦测范围内, 用户开始向左滑动。 S1中的对象 " 2" 成为浮动焦点对象, 并 和 S2中的对象 " 1 " 组成浮动组。 浮动组 " 12" 随着用户的滑动向左移动, 当 浮动组右端 "跨越" 了右边的一个对象槽时, 该对象槽生成浮动焦点对象的克 隆 " 2" 。 生成处理一般情况下只生成浮动焦点对象的克隆, 但是在 "小数点 拖动处理" 和 "初始零拖动处理" 中有特殊情况存在, 具体参考 "小数点拖动 处理" 和 "初始零拖动处理" 的详细流程。
如图 18A、 18B所示, "跨越 "的具体步骤如下。 图 18A示出了向右跨越, 当浮动组" 123 "向右移动, 并且其右端边缘越过 S1的四分之三处(从左向右) 时, 即为浮动组 "跨越" 了 Sl, 这个时候执行消除操作, S1中的对象 "4"被 消除。 当浮动组 " 123 " 向左移动, 并且其右端边缘越过 S1的四分之三处 (从 右向左) 时, 即为浮动组 "跨越" 了 Sl, 这个时候执行生成操作, S1中生成 浮动焦点对象的克隆 " 2" 。
小数点拖动处理的细化步骤如图 20所示。 首先, 小数点独自成为浮动组。 然后, 检测滑动方向是向左滑动还是向右滑动, 若是向左滑动则判断小数点左 边是否有对象存在。 在有对象存在的前提下, 根据对象是数字对象还是负号对 象分别进行处理。 对于数字对象的情况, 在小数点跨越左边对象的对象槽的情 况下, 进行置换处理, 在小数点没有跨越左边对象的对象槽的情况下, 返回到 检测滑动方向的步骤。 对于负号对象的情况, 小数点与负号对象组成浮动组, 在小数点跨越了左边对象槽的情况下, 在小数点右边生成零, 然后返回检测滑 动方向的步骤。 相反, 在小数点左边没有对象存在的情况下, 当小数点跨越了 左边对象槽的时候, 在小数点右边生成零, 进而返回到检测滑动方向的步骤。
下面是滑动方向是向右滑动的处理过程。 首先, 判断当前浮动组是否为 , 如果是则解除浮动组 , 使小数点独自成为浮动组, 然后再进入后 续的步骤, 如果当前浮动组不是 则可以直接进入后续的步骤。 接着, 判 断小数点右边是否有数字对象存在, 若右边没有数字对象则返回到检测滑动方 向的步骤, 若右边存在数字对象则进一步判断小数点是否跨越右边对象的对象 槽, 如果跨越了则进行置换处理, 然后返回检测滑动方向的步骤, 如果没有跨 越则直接返回到检测滑动方向的步骤。 图 20中所进行的置换处理请具体参见图 21A、 21B和 21C, 其中图 21A 示出了用户从 S2开始向右滑动的置换处理。用户从 S2开始向右滑动, S2中的 小数点对象成为浮动焦点, 并单独组成浮动组, 当小数点向右跨越了 S1时, S1中原来的对象 " 2"被置换到左边的对象槽 Sl。 图 21B示出了用户从 SI开 始向左滑动的置换处理。 用户从 S1开始向左滑动, S1中的小数点对象成为浮 动焦点, 并单独组成浮动组, 当小数点向左跨越了 S2时, S2中原来的对象 " 1 " 被置换到右边的对象槽 Sl。 用户继续向左滑动, 当跨越 S3时, 左边已经没有 可以置换的对象, 在空出来的 S2中生成零。 图 21C示出了有负号的情况, 首 先用户从 S1开始向左滑动, 然后, 小数点独立成为浮动组, 当小数点向左跨 越了 S2时, S2中原来的对象 " 1 " 被置换到右边的对象槽 Sl。 接着, 如果用 户继续向左滑动, 则组成新的浮动组 。 最后, 如果此时用户再向右移动 时, 则解除浮动组 , 小数点独自成为浮动组。
在最后, 还需要进行归位的操作和规格化处理。 归位的处理请参见图 19A 和 19B。如图 19A所示, 当用户拖动结束时, 浮动组并不是刚好与对象槽吻合, 浮动组右端所在对象槽没有对象的情况下,则浮动组向右归位。如图 19B所示, 当用户拖动结束时, 浮动组并不是刚好与对象槽吻合, 浮动组右端所在对象槽 有一个对象 " 4" , 则浮动组向左归位。
规格化处理是指依据以下的原则对对象槽组中的数字串进行处理: (1 ) 没有小数点的情况下, 最左边有若干个零, 则全部清除, 保证最左边的数字对 象不为零; (2) 如果最左边时小数点, 则在小数点左边的对象槽中生成一个 零; (3 )如果数字槽组中只有一个负号, 则将数字槽组恢复为初始状态; (4) 如果数字槽组中只有一连串 0, 则将数字槽组恢复为初始状态; (5 )有小数点 的情况下, 除非其整数部分只有一个 0或一连串 0, 否则其整数部分遵循: 1 个 0的情况下不做处理, 一连串 0的情况需要消除最左边的所有 0, 只保留最 右边的 1个 0。
图 26A~26F示出了 A区域规格化处理的几种特殊情况的示例。 如图 26A 所示, 对象槽中处于编辑状态, 数字串最左边的 " 1 " 是编辑焦点, 若此时用 户在 B区域输入 0, 则数字串最左端会变成 "0" , 即数字串变成 " 023 " , 需 要将数字串变为正常的 " 23 " 。 如图 26B所示, 对象槽处于编辑状态, 数字串 最左边的 " 1 " 是编辑焦点, 若此时用户在 B区域输入小数点, 则数字串最左 端是小数点 " . " , 即数字串变成 " .23 " , 需要去掉小数点从而将数字串变为 正常的 " 23 " 。 如图 26C所示, 用户将小数点向左拖动, 用户结束拖动后, 数 字串最左端是小数点 " . " , 即数字串变成 " .12" , 需要去掉小数点从而将数 字串变为正常的 " 12"。 如图 26D所示, 用户将负号向右拖动, 开始清零处理, 用户拖动负号到最右端结束拖动, 最后最右端只有一个负号, 需要去掉负号变 成数字 " 0" 。 如图 26E所示, 用户进行初始零拖动, 拖动到左边时又改变方 向向右拖动, 最后小数点被消去, 数字串有三个 "0" , 需要去掉多余的 " 0" 。 如图 26F所示, 用户向右拖动零, 开始消除处理, 用户结束拖动后小数点被消 去, 最后数字串最左端有一个负号和两个 0, 即数字串 " -001 " , 需要消除多 余的 " -00" 。 上述内容就是 A区域的处理流程。 需要说明的是, A区域的处理流程可以 作为单独的实施例执行, 亦即, 在如图 2所示的数字输入编辑的用户交互界面 上, 可以通过 A区域处理流程的实施方式进行数字的输入和编辑。
下面是 B区域的处理流程。
B区域的处理流程 请参见图 22, B区域的处理为: 首先检査用户手势类型, 判断是单击还是 滑动, 若是单击, 则进一步判断单击位置所在区域, 是位于角按钮响应区、 中 央按钮响应区还是数字响应区, 分为三种情况来处理。 请结合图 23, 示出了 B 区域的各个响应区的布局, 图中阴影部分为响应遮罩区, 数字响应区位于轮盘 内, 中央按钮响应区位于轮盘内圈, 角按钮响应区位于轮盘外圈的四个角上。
若单击位置位于角按钮响应区, 则执行角按钮功能。 若单击位置位于中央 按钮响应区, 则执行中央按钮功能。 若单击位置位于数字响应区, 则进一步判 断 A区域对象槽是否处于编辑状态。 在判断是否处于编辑状态的步骤中, 请参 见图 24, 用户单击对象槽 S1时, S1中的对象 " 3 " 变为编辑焦点, 整个对象 槽处于编辑状态。 若 A区域对象槽处于编辑状态则进行修改处理, 若处于非编 辑状态则进行输入处理。 输入处理是指当 A区域的数字串处于普通状态(非编 辑状态) , 此时用户在 B区域输入数字或小数点, 将会在 A区域数字串的末尾 (最右端)插入用户的输入值, 具体请参见图 25A, A区域当前数字为 " 123 ", 用户在 B区域输入 " 5 " , 原来的数字组 " 123 "整体向左移动一个对象槽, 并 在最右端 SO生成对象 " 5 " 。 修改处理是指当 A区域的数字串处于编辑状态, 此时用户在 B区域输入数字或小数点,将会改变 A区域数字串中的编辑焦点对 象为用户的输入值, 并还原数字串为普通状态。 请参见图 25B, A区域当前数 字为 " 123 " , 处于编辑状态并且 S1中的对象 " 2" 是编辑焦点, 用户在 B区 域输入 " 5 " , 原来在 S1中的编辑焦点对象 " 2" 被修改成 " 5 " , 并且取消了 焦点状态, 对象槽组恢复为普通状态。 当然, 若单击位置位于非响应区, 则不 作任何的处理。
还有一种如图 25C和 25D的特殊情况。 在图 25C中, 当前数字串处于普 通状态, 并且已经有一个小数点, 此时用户在 B区域输入小数点 " . " , 这次输 入没有任何效果。 在图 25D中, 当前数字串处于编辑状态, 并且已经有一个小 数点, 用户在 B区域输入小数点 " . " , 此时会取消编辑状态。
以下是滑动手势的处理。 首先侦测用户输入位置, 保存上一帧用户输入位 置。 然后对比上一帧用户输入位置和当前帧用户输入位置, 只有在用户手势是 从非响应区(也成为背景区域)滑动至数字响应区的情况下才进入后续的处理, 否则 (非响应区滑动至非响应区、 数字响应区滑动至数字响应区、 数字响应区 滑动至非响应区) 继续第一步的侦测用户输入位置的步骤。
在用户手势是从非响应区滑动至数字响应区的情况下,判断 A区域对象槽 是否处于编辑状态 (是否处于编辑状态请参见图 24) , 若处于编辑状态则进行 如图 25B所示的修改处理,若处于非编辑状态则进行如图 25A所示的输入处理。
需要说明的是, B区域的处理流程可以作为单独的实施例执行, 亦即, 在 如图 2所示的数字输入编辑的用户交互界面上, 可以单独通过 B区域处理流程 的实施方式进行数字的输入和编辑。 基于触摸屏的数字输入编辑方法的实施例 (简化方案 1 ) 本实施例针对前述的基于触摸屏的数字输入编辑方法做了一定的简化, 是 在前述的基于触摸屏的数字输入编辑组件上所实施的方法, 该方法是基于图 2 所示的 A区域上所做的操作。这一方案的主体是针对滑动手势的数字输入编辑, 具体过程如下。
首先, 检测用户在数字显示区域中的手势的类型, 当手势是滑动类型时进 行后续的步骤。 然后, 检测用户输入位置在数字显示区域中的子区域, 当输入 位置是位于数字和小数点构成的子区域内时, 进行后续的步骤。 接着, 检测当 前数是为零, 只有当前数为非零时进行后续的步骤。 最后, 检测用户处理的对 象类型, 当所处理的是数字时进行数字拖动处理: 生成数字浮动组, 若向左滑 动则进行生成处理, 若向右滑动则进行消除处理。 对数字的拖动处理的具体示 例在前述的实施例中已经有过详细的描述, 在此不再赘述。
为了更好的效果, 本实施例可以增加对单击手势的处理。 较佳的, 在检测 出用户手势是单击类型时, 先检査用户输入位置在数字显示区域中的子区域, 当输入位置是位于数字和小数点构成的子区域内时进行后续的步骤; 然后, 判 断对象槽状态, 当对象槽为普通状态时修改成编辑状态, 当对象槽为编辑状态 时基于输入位置是否位于编辑焦点对象之上进行操作: 当输入位置位于编辑焦 点对象之上时取消编辑状态, 当输入位置位于编辑焦点对象之外时改变编辑焦 占。
为了更好的效果, 本实施例可以增加单击操作中对数字的正负号的处理。 较佳的, 当单击操作中输入位置位于紧挨数字和小数点构成的子区域的左边的 一个空对象槽或者带有负号的对象槽时, 若当前数为负值则消去负号, 若当前 数为正值则生成负号。
为了更好的效果, 本实施例可以增加滑动操作中的输入位置位于数字和小 数点构成的子区域之外的这一情况的处理。 较佳的, 在滑动操作中当输入位置 位于数字和小数点构成的子区域之外时, 首先, 若输入位置位于紧挨数字和小 数点构成的子区域的左边的一个空对象槽或者有负号的对象槽时, 进行后续的 步骤, 否则回到检测用户输入位置在数字显示区域中的子区域的步骤; 接着, 检测滑动方向是向左滑动还是向右滑动, 若向左滑动则回到检测用户输入位置 在数字显示区域中的子区域的步骤, 若向右滑动则进行清零处理。
为了更好的效果, 本实施例可以增加滑动操作中对当前数为零时的处理。 较佳的, 在滑动操作中检测出用户输入位置所在子区域位于数字和小数点构成 的子区域内时, 若当前数为零, 则进行初始零的拖动处理。 首先生成零浮动子 串; 在当前的零越过左边对象槽时在零的右边生成小数点; 然后组成零点浮动 子串; 最后, 检测滑动方向是向左滑动或是向右滑动, 若向左滑动则做生成处 理, 若向右滑动则零点浮动子串变为零浮动子串后进行消除处理。
为了更好的效果, 本实施例可以增加对小数点拖动的处理。 当所处理的是 小数点时进行小数点拖动处理的步骤如下: 检测是向左滑动或是向右滑动; 在 向左滑动的情况下, 判断小数点左边是否有数字对象存在, 若有数字对象存在 则在小数点跨越左边对象的对象槽之时进行置换处理, 若无数字对象存在则在 小数点跨越左边对象的对象槽之时在小数点右边生成零; 在向右滑动的情况 下, 判断小数点右边是否有数字对象存在, 若有数字对象存在则在小数点跨越 右边对象的对象槽之时进行置换处理。 基于触摸屏的数字输入编辑方法的实施例 (简化方案 2) 本实施例针对前述的基于触摸屏的数字输入编辑方法做了一定的简化, 是 在前述的基于触摸屏的数字输入编辑组件上所实施的方法, 该方法是基于图 2 所示的 B区域上所做的操作。这一方案的主体是针对滑动手势的数字输入编辑, 具体过程如下。
首先, 检査用户手势类型, 当手势为滑动操作时进入后续的步骤。 接着, 检测当前帧用户输入位置, 保存上一帧用户输入位置, 根据上一帧用户输入位 置和当前帧用户输入位置的对比结果判断滑动手势的类型, 当滑动是从数字响 应区域之外滑动到数字响应区域内时进入后续的步骤; 最后, 判断数字显示区 域内的对象槽是否处于编辑状态, 若处于编辑状态则进行修改处理, 若位于非 编辑状态则进行输入处理。 修改处理和输入处理等的具体示例请参见前述的实 施例, 在此不再赘述。
为了体现更好的效果, 本实施例对单击手势进行了设定。 较佳的, 当手势 为单击操作时, 进行下面的步骤: 判断单击位置所在区域, 若为功能响应区域 则执行相应的功能, 若为数字响应区域则进入后续的步骤; 判断数字显示区域 内的对象槽是否处于编辑状态, 若处于编辑状态则进行修改处理, 若位于非编 辑状态则进行输入处理。 上述实施例是提供给本领域普通技术人员来实现和使用本发明的, 本领域 普通技术人员可在不脱离本发明的发明思想的情况下, 对上述实施例做出种种 修改或变化, 因而本发明的保护范围并不被上述实施例所限, 而应该是符合权 利要求书所提到的创新性特征的最大范围。
