输入方法、 装置及终端 技术领域 本发明涉及通信领域, 具体而言, 涉及一种输入方法、 装置及终端。 背景技术 目前, 日常的办公软件大都是基于 windows操作系统的, 以往的移动终端设备由 于系统的局限性, 多数不支持正常的办公软件, 也不能代替笔记本的位置。 随着 win8 系统的推进,当前的移动终端由原来的纯娱乐设备逐渐转型为办公娱乐二合一的设备。 在旅行、 出差的情况下, 使用体积、 重量更小的移动终端设备作为办公设备, 有着更 为便携的利用价值。 但是, 由于终端的体积小, 且大多数都采用触摸屏输入方式, 所以, 屏幕的大小 就制约了虚拟键盘的大小。 虚拟键盘的每个按键的触摸区域也变得非常小, 造成触摸 不便, 易造成误触摸; 而且, 虚拟键盘也会占据屏幕的一部分空间, 导致用户可视面 积变小, 不方便查阅。 发明内容 本发明实施例提供了一种输入方法、 装置及终端, 以至少解决相关技术中, 虚拟 键盘按键区域小, 易造成误触摸, 且虚拟键盘会占据终端屏幕的一部分空间, 导致用 户可视面积较小, 不方便查阅的问题。 根据本发明实施例的一个方面, 提供了一种输入方法, 包括: 在终端外部显示虚 拟立体键盘; 检测到虚拟立体键盘上有按键输入; 根据按键输入确定按键值, 并在终 端的屏幕上显示该按键值。 优选地, 根据按键输入确定按键值包括: 计算按键输入相对于终端的位置坐标; 将按键输入的位置坐标与预先设定的虚拟立体键盘的坐标集合进行匹配; 根据匹配结 果确定按键值。 优选地, 在检测到虚拟立体键盘上有按键输入之前, 上述方法还包括: 利用红外 反射特性检测虚拟立体键盘上是否有按键输入。 优选地, 利用红外反射特性检测虚拟立体键盘上是否有按键输入包括: 利用红外 收发装置旋转检测虚拟立体键盘上是否有按键输入。 优选地, 计算按键输入相对于终端的位置坐标包括: 当红外收发装置接收到反射 的红外线时, 记录反射时间以及红外收发装置相对于预定轴转过的角度; 根据反射时 间以及红外线的速度, 计算按键输入到红外收发装置的距离; 根据按键输入到红外收 发装置的距离和红外收发装置相对于预定轴转过的角度计算按键输入的位置坐标。 优选地, 红外线收发装置上设置有可旋转的电机。 优选地,虚拟立体键盘的坐标集合是根据预先设置的虚拟立体键盘所占区域大小、 按键大小、 按键间距、 各个按键与终端的距离计算出的虚拟立体键盘上的各个按键的 坐标范围的集合。 优选地, 虚拟立体键盘是标准键盘或者用户自定义的键盘格式。 根据本发明实施例的另一个方面, 提供了一种输入装置, 包括: 第一显示模块, 设置为在终端外部显示虚拟立体键盘; 检测模块, 设置为检测到虚拟立体键盘上有按 键输入; 确定模块, 设置为根据按键输入确定按键值; 第二显示模块, 设置为在终端 的屏幕上显示按键值。 优选地, 确定模块包括: 计算单元, 设置为计算按键输入相对于终端的位置坐标; 匹配单元, 设置为将按键输入的位置坐标与预先设定的虚拟立体键盘的坐标集合进行 匹配; 确定单元, 设置为根据匹配结果确定按键值。 优选地, 检测模块还设置为利用红外反射特性检测虚拟立体键盘上是否有按键输 入。 根据本发明实施例的再一个方面,提供了一种终端,包括上述任一种的输入装置。 通过本发明实施例,将键盘以 3d虚拟的方式呈现在终端的一侧,无需占用终端屏 幕的空间, 方便用户查阅终端屏幕上显示的内容; 用户可以点击该虚拟立体键盘的按 键, 终端确定按键的按下以及确定按键值, 实现快速便捷的文本输入; 且用户可以自 定义虚拟立体键盘的大小以及按键之间的间距, 从而在一定程度上降低了误触摸的概 率。 附图说明 此处所说明的附图用来提供对本发明实施例的进一步理解,构成本申请的一部分, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在 附图中- 图 1是根据本发明实施例的输入方法的流程图; 图 2是根据本发明实施例的输入装置的结构框图; 图 3是根据本发明优选实施例的输入装置的结构框图; 图 4是根据本发明优选实施例的终端的结构框图; 图 5是根据本发明优选实施例的虚拟立体键盘以及终端的整体示意图; 图 6是根据本发明优选实施例的虚拟立体键盘以及终端的截面示意图; 图 7是根据本发明优选实施例的计算按键输入的坐标系的示意图; 图 8是根据本发明优选实施例的输入方法的流程图。 具体实施方式 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。 下面将参考附图并结合实施例来详细说明本发明实施例。 本发明实施例提供了一种输入方法, 图 1是根据本发明实施例的输入方法的流程 图, 如图 1所示, 包括如下的步骤 S102至步骤 S106。 步骤 S102, 在终端外部显示虚拟立体键盘。 步骤 S104, 检测到虚拟立体键盘上有按键输入。 步骤 S106, 根据按键输入确定按键值, 并在终端的屏幕上显示该按键值。 相关技术中, 虚拟键盘按键区域小, 易造成误触摸, 且虚拟键盘会占据终端屏幕 的一部分空间, 导致用户可视面积较小, 不方便查阅。 本发明实施例中, 将键盘以 3d 虚拟的方式呈现在终端的一侧, 无需占用终端屏幕的空间, 方便用户查阅终端屏幕上 显示的内容; 用户可以点击该虚拟立体键盘的按键, 终端确定按键的按下以及确定按 键值, 实现快速便捷的文本输入; 且用户可以自定义虚拟立体键盘的大小以及按键之 间的间距, 从而在一定程度上降低了误触摸的概率。 在实际应用中, 可以通过立体投影技术实现在终端外部显示虚拟立体键盘。 虚拟 立体键盘通过嵌入在终端设备一端的立体输出模块进行呈现, 其输出的立体影像的区 域大小, 按键大小, 按键间距等参数可以预置, 即立体影像是可控的。 虚拟立体键盘 可以是标准键盘, 也可以是用户自定义的键盘格式。 可以通过存储在终端中的用户可能输入的内容 (如, 字母、 笔画) 与按键位置的 对应关系确定用户按的是哪个键, 从而在终端屏幕上进行显示。 本发明实施例提供了 一种优选实施方式,步骤 S106中根据按键输入确定按键值包括:计算按键输入相对于 终端的位置坐标; 将按键输入的位置坐标与预先设定的虚拟立体键盘的坐标集合进行 匹配; 根据匹配结果确定按键值。 本优选实施方式中, 根据虚拟立体键盘所占区域大 小、 按键大小、 按键间距、 各个按键与终端的距离计算出虚拟立体键盘上的各个按键 的坐标范围 (因为每个按键是一个立方体, 所以按键位置可以是坐标范围, 当然也可 以是一个坐标值, 比如按键中心的坐标值) 的集合, 预先存储在终端中, 当用户有按 键动作进行输入时, 计算按键输入的坐标, 与该集合进行匹配, 从而确定用户的输入。 需要说明的是, 虚拟立体键盘的坐标集合就是上述各个按键的坐标范围的集合。 上述虚拟立体键盘所占区域大小、 按键大小、 按键间距、 各个按键与终端的距离等参 数, 可以是用户自定义的。 计算按键输入相对于终端的位置坐标, 可以利用红外测距定位来实现, 当然, 也 可以通过其它监测、 测距的方式实现。 现对红外测距确定按键输入的方式介绍如下: 在步骤 S104之前,上述方法还包括:利用红外反射特性检测虚拟立体键盘上是否 有按键输入。 优选地, 利用红外收发装置旋转检测虚拟立体键盘上是否有按键输入。 计算按键输入相对于终端的位置坐标包括: 当红外收发装置接收到反射的红外线 时, 记录反射时间以及红外收发装置相对于预定轴转过的角度; 根据反射时间以及红 外线的速度, 计算按键输入到红外收发装置的距离; 根据按键输入到红外收发装置的 距离和红外收发装置相对于预定轴转过的角度计算按键输入的位置坐标。 优选地, 上述红外收发装置旋转可以通过在红外线收发装置上设置可旋转的电机 来实现。 本发明实施例还提供了一种输入装置, 该装置可以设置为实现上述输入方法。 图 2是根据本发明实施例的输入装置的结构框图, 如图 2所示, 该输入装置包括第一显 示模块 22、 检测模块 24、 确定模块 26和第二显示模块 28。 下面对其结构进行详细描 述。 第一显示模块 22, 设置为在终端外部显示虚拟立体键盘; 检测模块 24, 连接至, 第一显示模块 22设置为检测到第一显示模块 22显示的虚拟立体键盘上有按键输入; 确定模块 26, 连接至检测模块 24, 设置为根据检测模块 24检测到的按键输入确定按 键值; 第二显示模块 28, 连接至确定模块 26, 设置为在终端的屏幕上显示确定模块 26确定的按键值。 如图 3所示, 确定模块 26包括: 计算单元 262, 设置为计算按键输入相对于终端 的位置坐标; 匹配单元 264, 连接至计算单元 262, 设置为将按键输入的位置坐标与预 先设定的虚拟立体键盘的坐标集合进行匹配; 确定单元 266, 连接至匹配单元 264, 设 置为根据匹配结果确定按键值。 优选地,检测模块 24还设置为利用红外反射特性检测虚拟立体键盘上是否有按键 输入。 优选地, 可以利用红外收发装置旋转检测虚拟立体键盘上是否有按键输入。 优选地, 计算单元 262包括: 记录子单元, 设置为当红外收发装置接收到反射的 红外线时, 记录反射时间以及红外收发装置相对于预定轴转过的角度; 第一计算子单 元, 设置为根据反射时间以及红外线的速度, 计算按键输入到红外收发装置的距离; 第二计算子单元, 设置为根据按键输入到红外收发装置的距离和红外收发装置相对于 预定轴转过的角度计算按键输入的位置坐标。 优选地, 红外线收发装置上设置有可旋转的电机。 本发明实施例还提供了一种终端, 包括上述任一种的输入装置。 需要说明的是, 装置实施例中描述的输入装置、 终端对应于上述的方法实施例, 其具体的实现过程在方法实施例中已经进行过详细说明, 在此不再赘述。 由以上描述可知, 本发明实施例采用立体呈现的方式, 将虚拟键盘呈现在终端设 备的一边, 例如, 终端设备放在桌面上时, 虚拟立体键盘就呈现在用户与终端设备之 间, 方便用户进行输入。 本发明实施例基于立体投影以及红外测距定位, 实现了虚拟 立体键盘。 利用立体输出模块在终端设备的一侧输出虚拟立体键盘, 使用户能清晰的 看到三维的键盘; 利用感应模块实现确认按键值, 感应模块利用红外反射的特性, 监 测是否有按键输入; 当监测到有按键输入后, 通过红外收发装置, 由红外线反射时间 以及速度计算出用户输入介质所处位置的坐标,并将坐标与系统中的坐标系进行匹配, 进而确定按键值。 为了使本发明实施例的技术方案和实现方法更加清楚, 下面将结合优选的实施例 对其实现过程进行详细描述。 图 4是根据本发明优选实施例的终端的结构框图, 如图 4所示, 可以通过虚拟立 体键盘实现输入的终端 40包括: 虚拟立体键盘处理模块 402、 立体输出模块 404和感 应模块 406,其中,虚拟立体键盘处理模块 402与立体输出模块 404以及感应模块 406 通过双向通讯接口连接。 下面对各个模块的功能进行详细描述。 虚拟立体键盘处理模块 402, 作为实现虚拟立体键盘的核心, 控制立体输出模块
404以及感应模块 406的动作。 虚拟立体键盘处理模块 402包含了软件部分以及硬件 部分。当用户使用虚拟立体键盘时,虚拟立体键盘处理模块 402控制立体输出模块 404 输出相应的键盘, 并发送命令至感应模块 406, 使其实时监测是否有用户按下按键。 立体输出模块 404 (实现了上述第一显示模块 22的功能)可以输出预置的若干种 键盘格式, 每种键盘格式都有相应的参数, 这些参数用以配置每个按键的坐标范围, 组成坐标系。 感应模块 406 (实现了上述检测模块 24、确定模块 26和第二显示模块 28的功能) 监测是否有按键输入, 并将确认按键值所需的参数发送至虚拟立体键盘处理模块 402 进行计算, 以确认按键值, 完成按键的有效输入, 即在终端的屏幕上显示用户的输入。 在一个优选实施例中, 在立体输出模块 404的下方是感应模块 406, 其作用是判 定按键的有效输入。 感应模块 406中包含有一组红外收发装置以及一个微型电机, 设 置为测量用户的输入介质距离感应模块 406之间的距离。 其实现原理是: 将红外收发 装置固定在微型电机 (即步进电机) 上, 微型电机带动红外收发装置在虚拟立体键盘 的一侧 180度范围内快速扫描是否有按键按下, 当红外收发装置接收到反射的红外线 时, 此时记录反射时间以及微型电机旋转的角度, 通过红外收发的时间及速度计算出 红外收发装置距离输入介质的距离, 再通过微型电机的角度计算出输入介质所处位置 的坐标。 将该坐标值与预置的坐标系进行匹配, 即可得出输入介质所处位置对应于键 盘中的某个特定的按键值。 立体输出模块 404与感应模块 406与终端设备的虚拟立体键盘处理模块 402 (可 以通过终端的 CPU实现)通过串口总线进行通讯。终端设备的虚拟立体键盘处理模块 402控制立体输出模块 404输出相应的键盘格式、 尺寸以及每个按键的大小, 然后将 键盘尺寸、 按键大小等参数进行处理, 与感应模块 406返回的距离参数以及位置参数 进行拟合, 用以确定有效的按键输入。 图 5是根据本发明优选实施例的虚拟立体键盘以及终端的整体示意图, 如图 5所 示, 当终端 40放置在桌面上时, 其中的一侧有立体输出模块 404以及感应模块 406。 当用户需要使用虚拟立体键盘时, 可以通过操作终端 40 的界面软件打开虚拟立体键 盘, 此时, 虚拟立体键盘处理模块 402控制立体输出模块 404输出标准键盘的立体影 像(当然也可以用户自定义的键盘格式显示虚拟立体键盘)。 与此同时, 虚拟立体键盘 处理模块 402控制感应模块 406进行实时检测用户输入介质 (例如, 手指) 的距离以 及位置。虚拟立体键盘 42是立体输出模块 404输出的虚拟立体键盘的影像,其区域大 小 (WxL)、 按键间距 d、 按键大小 e及其距离立体输出模块 404的距离 s均为可调参 数。 在选择相应键盘的模式下, 立体输出模块 404所输出的虚拟立体键盘的参数都是 可控的, 即其中的^¥、 L、 d、 e以及 s均可预置指定的参数, 这些参数都会被应用在 确定按键值的算法中。 在已知上述参数的情况下, 可以计算出每个按键所处区域的坐 标范围。 图 6是根据本发明优选实施例的虚拟立体键盘以及终端的截面示意图, 如图 6所 示, 平面 602为终端设备所放置的平面, 可以是桌面或者其它平面, 本优选实施例以 桌面为例。当终端 40放置在平面 602上时,感应模块 406所在的位置与平面 602的距 离为 a, 把距离平面 602为^ 与其平行的虚拟平面 604作为虚拟 sensor层, 用以确认 是否有按键按下, a 的值越小越好。 当输入介质 (此处以手指为例) 点击虚拟立体键 盘 42上的某个按键时, 手指首先穿过虚拟键盘区域, 再穿过该按键垂直投影在 sensor 层上的区域,且当手指接触到桌面时,按键动作结束。因为要避免误报按键事件, sensor 层要尽量靠近桌面,避免当有手指按下时,其它手指由于太靠近桌面被误检测并上报。 即当感应模块 406检测到手指穿过 sensor层时, 会反馈按键按下的事件上报至虚拟立 体键盘处理模块 402。 虚拟立体键盘的水平方向中心线距离桌面的距离为!), b必须大 于或者等于 a。 虚拟立体键盘的每个按键之间的距离为 d, 定义每个按键都为边长为 e 的立方体。 由上述参数可以确定每个按键所处区域的坐标范围。 图 7是根据本发明优选实施例的计算按键输入的坐标系的示意图, 如图 7所示, 系统将感应模块 406的中心作为坐标原点, 圆圈处为手指所处位置, 手指距离坐标原 点的距离为 c, 以终端的一侧所在的线作为 X轴, 沿着立体输出方向的线作为 y轴, 整个坐标系位于 sensor层所在的平面, y轴同时作为微型电机的 0度角方向。因为 sensor 层位于虚拟立体键盘的正下方, 所以每个虚拟按键的位置垂直对应在 sensor层上后都 相应有一个同等大小的区域, 这个区域在整个坐标系中有个范围。 每个按键坐标均是 一个范围: Xl<X< , yi<y<y2, 所有按键的坐标范围集中在一起成为虚拟立体键盘的 坐标系, 当红外收发装置检测到手指后, 记录当前微型电机转动的角度01。 通过红外收发运行的时间 t, 以及红外的速度^ 即可计算出检测到的手指距离红 外收发装置的距离 c, c=vt/2。 另外, 根据微型电机的转动角度 α, 可以计算出手指所 处位置的坐标: x=c*sina, y=c*cosa。 计算出手指所触发位置的坐标后,将该坐标与坐标系进行匹配,进而确定按键值。 当用户操作虚拟立体键盘时, 按下每个按键的动作实际上是以敲击在桌面上作为结束 动作的, 这样也确保每次按键按下时, 手指都会穿过 sensor层的坐标区域, 避免出现 漏判定的情况。 图 8是根据本发明优选实施例的输入方法的流程图, 如图 8所示, 包括如下的步 骤 S802至步骤 S810。 步骤 S802,当用户启用虚拟立体键盘时,控制中心(即虚拟立体键盘处理模块 402) 发送开启指令, 将立体输出模块 404以及感应模块 406依次打开。 立体输出模块 404 将按照预定协议输出其中一种形式的立体键盘。 步骤 S804, 感应模块 406在不间断扫描监测是否有手指穿过 sensor层, 即有按键 输入。 以顺序扫描完整个键盘区域作为一个周期, 当一个周期结束, 未发现按键按下, 会自动重新启用步骤 S802。 当监测到有手指穿过 sensor层时, 流程转为步骤 S806。 步骤 S806, 记录当前微型电机的旋转角度01, 以及红外收发装置的发射接收的时 间差。 步骤 S808, 将步骤 S806得到的数据通过协议传送至虚拟键盘的虚拟立体键盘处 理模块 402。 步骤 S810, 虚拟立体键盘处理模块 402根据相应的算法, 以及提供的参数, 计算 出手指所处位置对应在 sensor层的坐标, 并且将坐标与预设的坐标系匹配, 得出坐标 值, 然后再执行步骤 S804。 通过上述步骤, 即可完成虚拟立体键盘的使用。 需要说明的是, 上述是以红外监 测的方式感应按键输入的, 实施者也可通过其他监测、 测距的方式, 但总体都是以计 算输入介质 (或按键位置) 的坐标实现按键输入。 需要说明的是, 在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的 计算机系统中执行, 并且, 虽然在流程图中示出了逻辑顺序, 但是在某些情况下, 可 以以不同于此处的顺序执行所示出或描述的步骤。 综上所述, 根据本发明的上述实施例, 提供了一种输入方法、 装置及终端。 通过 本发明实施例,将键盘以 3d虚拟的方式呈现在终端的一侧,无需占用终端屏幕的空间, 方便用户查阅终端屏幕上显示的内容; 用户可以点击该虚拟立体键盘的按键, 终端确 定按键的按下以及确定按键值, 实现快速便捷的文本输入; 且用户可以自定义虚拟立 体键盘的大小以及按键之间的间距, 从而在一定程度上降低了误触摸的概率。 显然, 本领域的技术人员应该明白, 上述的本发明实施例的各模块或各步骤可以 用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算 装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 或者将它们分别制作成各个集成电 路模块, 或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本 发明实施例不限制于任何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
