为使本领域技术人员更好地理解本发明的技术方案， 下面结 合附图和具体实施方式对本发明的穿戴式触控装置和穿戴式触控 方法作进一步详细的描述。
根据本发明的一个方面， 提供一种穿戴式触控装置， 包括载 体、 图案发射单元、 图像釆集单元、 图像监测单元和处理单元， 其中： 所述载体能穿戴； 所述图案发射单元用于向触控端能触摸 到的触控面发射扫描图案； 所述图像釆集单元用于釆集所述扫描 图案在所述触控面上投射形成的图像， 并将釆集图像的图像信息 发送至所述处理单元； 所述图像监测单元用于监测所述扫描图案 在所述触控面的各区域的当前光能量， 并将当前光能量信息发送 至所述处理单元； 所述处理单元用于对釆集图像的图像信息和当 前光能量信息进行处理， 以确定所述触控端在所述触控面上的触 控位置并产生相应的命令信息。
根据本发明的另一个方面， 提供一种穿戴式触控方法， 包括 以下步骤： 向触控端能触摸到的触控面发射扫描图案； 釆集所述 扫描图案在所述触控面上投射形成的图像， 并同时监测所述扫描 图案在所述触控面的各区域的当前光能量信； 对釆集图像的图像 信息和当前光能量信息进行处理， 从而确定出所述触控端在所述 触控面上的触控位置并产生相应的命令信息。
在本发明实施例中， 用户无需直接接触该穿戴式触控装置即 可进行触控， 且该穿戴式触控装置体积小巧、 便于携带， 相应的 穿戴式触控方法触控准确， 适用面较广。 实施例 1 :
本实施例提供一种穿戴式触控装置和相应的穿戴式触控方 法。
如图 1 所示， 本实施例中的穿戴式触控装置包括载体 1、 图 案发射单元 2、 图像釆集单元 3、 图像监测单元 4和处理单元 5。
载体 1能穿戴， 例如， 穿戴于人体手指上。
图案发射单元 2用于向触控端能够触摸到的触控面发射扫描 图案。
图像釆集单元 3用于釆集所述扫描图案在所述触控面上投射 形成的图像， 并将釆集到的釆集图像的图像信息发送至处理单元 5。 图像监测单元 4用于监测所述扫描图案在所述触控面的各区 域的当前光能量信息， 并将当前光能量信息发送至处理单元 5。
处理单元 5用于对釆集图像的图像信息和当前光能量信息进 行处理， 以确定触控端在所述触控面上的触控位置并产生相应的 命令信息。
优选的是， 图案发射单元 2和图像釆集单元 3均设置于载体 1上、且位于载体 1的同一区域内， 即在同一个区域内包括图案的 发射部分和图像的接收部分， 以便于发射的扫描图案与接收的釆 集图像之间的定点识别和比较。 在本实施例中， 如图 1 所示， 载 体 1优选为闭合环状， 图像监测单元 4也设置于载体 1上， 且图 案发射单元 2和图像釆集单元 3设置于载体 1的一端， 图像监测 单元 4设置于相对的另一端。
图案发射单元 2为红外投影式图案发射单元， 图像釆集单元 3为红外式图像釆集单元， 例如摄像头（camera ) ， 可以理解， 摄 像头可以是可旋转摄像头， 以在触控装置与触控面的相对位置变 化时， 保证图案发射单元 2、 图像釆集单元 3 和图像监测单元 4 的正常工作。 图像监测单元 4 为红外式图像监测单元， 例如光学 检测传感器 （op t i ca l sens or ) 。 另外， 图案发射单元 1发射的 扫描图案例如为网格形状的图案， 即本实施例中， 图案发射单元 2 发射的扫描图案为红外网格（ inf rared gr i d ) 图案， 也即红外矩 阵图案。 由于釆用相匹配的红外式的图案发射单元 2、 图像釆集单 元 3和图像监测单元 4， 因此在釆用该穿戴式触控装置时，触控端 与触控装置无需直接接触即可进行触控， 触控更灵活。
优选的是， 上述各单元均可选用体积较小的微型芯片实现， 以具有较小的体积， 从而保证该穿戴式触控装置的小巧体积以及 便携性。
同时优选的是， 载体 1可以釆用 PVC材料形成。 该材料结实、 绝缘， 使得设置于其内的各单元的结构和位置稳定， 保证该穿戴 式触控装置的有效工作， 还能保证人体的安全。
在本实施例中， 触控端可以与触控面直接接触或不接触， 且 触控面可以为规则平面、 不规则平面或曲面上。 任何一个平面、 具有凹凸点的不规则平面或曲面在其面积足够小的时候均可以被 视为一个平面， 并具有相应的坐标信息。 可以理解的是， 当触控 端不与触控面直接接触时， 虽然能够通过当前光能量信息和釆集 图像的图像信息确定出触控位置， 但此时由于触控端与触控面可 能相距一定的距离， 触控端在触控面上的投影与实际要触摸的点 之间存在一定的偏差， 因此经计算得到的触控位置可能存在一定 的触控定位误差。 容易理解的是， 触控端与触控面直接接触时， 由于触控端在触控面上的投影与实际要触摸的点基本一致， 因此 触控定位更^ "确。
在一种应用示例中， 触控端 7 (参见图 3 )为人体一只手的手 指， 载体 1 穿戴于人体另一只手的手指上， 触控端 7能触摸到的 区域为穿戴有载体 1的手的手掌。在另一种应用示例中， 触控端 7 为人体一只手的手指， 载体 1 穿戴于作为触控端 7的手指上， 触 控端 7 能触摸到的区域为人体另一只手的手掌。 一般的， 载体 1 距离触控端 7能触摸到的区域或距离触控端 7的距离越近， 图像 监测单元 4得到的光能量变化越准确， 触控的定位也相对更精确。
相应的， 图案发射单元 2、 图像釆集单元 3、 图像监测单元 4 和处理单元 5均设置在载体 1中， 且图案发射单元 2、 图像釆集单 元 3和图像监测单元 4均设置于载体 1靠近手心侧的外表层。 优 选的是， 图案发射单元 2、 图像釆集单元 3和图像监测单元 4的外 表面与载体 1的外表面齐平。
本实施例的穿戴式触控装置中， 处理单元 5 中还包括对比模 块与命令模块 （图 1 中未示出） ， 釆集图像的图像信息包括釆集 图像的图像坐标信息， 处理单元 5 内预存有位置坐标与命令信息 映射表、 扫描图案的初始光能量信息和图案坐标信息， 对比模块 用于将釆集图像的图像坐标信息和当前光能量信息分别与扫描图 案的图案坐标信息和初始光能量信息进行对比， 从而得到确定的 触控位置坐标信息； 命令模块用于根据位置坐标与命令信息映射 表， 将接收到的确定的触控位置坐标信息转化成相应的命令信息。 优选的是， 处理单元 5可以釆用微型处理器（例如单片机） 实现。 进一步的， 所述穿戴式触控装置还包括执行单元， 执行单元 用于根据接收到的命令信息执行相应的动作。
例如， 如图 2所示， 载体 1 中的图案发射单元 2 (例如红外 网格投影单元）和釆集图像用的图像釆集单元 3(例如红外摄像头） 均安装在载体 1 的靠近手心侧， 该穿戴式触控装置处于待机状态 或工作状态时， 图案发射单元 2 将持续向触控面 （例如穿戴有载 体 1的手的手心或手掌）发射红外网格投影， 例如， 将红外网格 6 投影在作为触控面 8的穿戴有载体 1 的手的手心或手掌上 （参见 图 3 ) 。 如图 3所示， 当对触控面 8进行触控时， 当触控端 7 (例 如人体手指） 落入红外网格范围内的某个区域时， 会挡住形成红 外网格图案的一部分红外光， 一方面手指所到之处的红外网格图 案受遮挡而发生光能量变化 （即产生光的损耗或损失） ， 当前光 能量被图像监测单元 4 (例如光学检测传感器）所釆集， 即当前光 能量信息被监测； 另一方面图像釆集单元 3釆集手指所到之处的 红外网格图案的变化， 即釆集红外网格图案在触控面 8 上投射形 成的图像。
处理单元 5 中预设有扫描图案的初始光能量信息和扫描图案 的图案坐标（本实施例中为红外网格坐标）信息， 图像监测单元 4 监测到的当前光能量信息和图像釆集单元 3釆集到的釆集图像的 图像坐标信息均反馈给处理单元 5，处理单元 5中的对比模块对上 述当前光能量信息和釆集图像的图像坐标信息进行处理、 分析， 若某区域的当前光能量信息相对初始光能量信息的变化量大于等 于设定值 （例如 5% ) ， 则初步确定该区域内包括近似触控点； 进 一步的， 对比模块对比釆集图像的图像坐标信息与扫描图案的图 案坐标信息， 当在对应的坐标处釆集图像与扫描图案之间发生变 化， 即可确定该坐标点为实际触控点， 得出相应的触控位置的坐 标； 进而根据位置坐标与命令信息映射表， 获取该触控位置的坐 标对应的命令信息。
利用该穿戴式触控装置， 当手指进行触控时， 图像监测单元 感知光能量变化， 并将该光能量变化信息传送给处理单元， 从而 可以确认有触控动作发生， 根据光能量变化与设定值之间的大小 关系将某区域初步确定为包括触控位置的近似区域； 同时， 图像 釆集单元获取手指遮挡扫描图案形成的投射图像， 相应地记录釆 集图像的图像坐标信息， 该图像坐标信息与扫描图案的图案坐标 信息进行对比， 确定釆集图像与扫描图案之间发生变化的对应坐 标， 从而得出精确的触控位置。
应该理解的是， 图案发射单元 2、 图像釆集单元 3和图像监 测单元 4 可以是除红外方式以外的其他方式的单元， 只需能互相 匹配即可， 而对其具体形式不做限定。 图案发射单元 1 所发射的 特定图案也可以是除网格图案之外的其他图案， 在具体应用中， 可以灵活地进行设置， 这里不再赘述。
相应的， 本实施例提供一种穿戴式触控方法， 包括以下步骤： 向触控端能触摸到的触控面发射扫描图案；
釆集所述扫描图案在所述触控面上投射形成的图像， 并同时 监测所述扫描图案在所述触控面的各区域的当前光能量信息； 对釆集图像的图像信息和当前光能量信息进行处理， 获得图 像变化以及光能量变化， 从而确定出触控端在触控面上的触控位 置并产生相应的命令信息；
进一步的， 根据与触控位置对应的命令信息执行对应的命令 动作。
其中， 釆集图像的图像信息包括釆集图像的图像坐标信息， 且预设有位置坐标与命令信息映射表、 扫描图案的初始光能量信 息和图案坐标信息， 并且上述方法中确定出触控端在触控面上的 触控位置并产生相应的命令信息的步骤包括以下步骤：
对比触控面的某区域内的当前光能量信息与扫描图案的初始 光能量信息， 当当前光能量信息相对初始光能量信息的变化量大 于等于设定值时， 则初步确定该区域内包括近似触控点；
对比该区域内的釆集图像的图像坐标信息与扫描图案的图案 坐标信息， 当在对应的坐标处釆集图像与扫描图案之间发生变化 时， 则确定该坐标点为实际触控点， 从而获得触控位置的坐标； 进而根据位置坐标与命令信息映射表， 获取与该触控位置的 坐标对应的命令信息。
图 4示出了该穿戴式触控方法的触控流程图。
穿戴式触控装置通过载体 1 穿戴于例如人体手指上， 开机初 始化过程中设定特定图案的初始光能量信息和图案坐标信息。
图案发射单元 2向作为触控面 8的例如手心或手掌上投射红 外网格图案 （Pa t tern ) 。
当无触控端 7 (例如人体手指） 执行触控时， 该穿戴式触控 装置保持待机状态。
当有人体手指执行触控时， 红外网格图案将发生变化， 图像 釆集单元 3 (例如摄像头）将釆集人体手指所到之处的红外网格图 案投射形成的图像， 同时图像监测单元 4 (例如光学检测传感器） 监测红外网格图案中的当前光能量信息。
上述在人体手指执行触控时形成的釆集图像的图像坐标信息 和当前光能量信息均传送到处理单元 5 进行处理、 分析， 首先通 过将当前光能量信息和初始光能量信息进行对比来确认有触控动 作发生， 并根据光能量变化与设定值之间的大小关系将某区域初 步确定为包括触控位置的近似区域； 然后， 进一步根据釆集图像 的图像坐标信息与扫描图案的图案坐标信息之间的对比， 当在对 应的坐标 （例如中心坐标） 处釆集图像与扫描图案之间发生变化 时， 则确定该坐标点为实际触控点， 从而得出精确的触控位置的 坐标； 进而根据与该触控位置的坐标对应的命令信息， 执行触控 命令。 实施例 2 :
本实施例提供一种穿戴式触控装置和相应的穿戴式触控方 法， 与实施例 1 相比， 该穿戴式触控装置中的各单元可以分离设 置于一个以上的载体上。 即在实施例 1 中， 图案发射单元、 图像 釆集单元、 图像监测单元和处理单元设置在同一个载体中； 而在 本实施例中， 可以将图案发射单元和图像釆集单元设置在一个载 体中， 而将图像监测单元和处理单元设置另一个载体中。
在本实施例中， 载体包括第一载体和第二载体， 第一载体和 第二载体釆用相同的材料形成。 例如， 图案发射单元和图像釆集 单元可以设置于第一载体上， 且位于第一载体的同一区域内； 而 图像监测单元设置于第二载体上， 第一载体和第二载体可以穿戴 在同一人的同一只手或者两只手上， 或者可以穿戴在不同人的手 上。
本实施例的穿戴式触控装置中的各单元的配置与实施例 1 中 的相应单元的配置相同， 这里不再赘述。
本实施例的相应的穿戴式触控方法与实施例 1 的穿戴式触控 方法相同， 均为通过图案发射单元发射红外矩阵图案， 当人体手 指触摸到触控面的红外矩阵图案的某些点上时， 图像监测单元就 监测到这些点处的红外光有损失 （光能量变化） ， 再根据图像釆 集单元釆集到的手指所到之处的红外网格图案的变化， 进而由处 理单元根据光能量变化和图案变化进行分析、 处理， 判断出触控 的具体位置， 得出准确的触控点坐标， 进而获取与该触控点坐标 对应的命令信息。 本发明中的穿戴式触控装置可以为可穿戴于人体手指的闭合 环状智能穿戴装置， 通过图案发射单元向触控端能触摸到的触控 面投射特定图案， 当手指进行触控时， 通过图像釆集单元釆集手 指所到之处特定图案投射形成的图像， 并配合图像监测单元监测 该图像的当前光能量信息， 处理单元对釆集图像的图像信息和当 前光能量信息进行分析和处理， 确定手指的触控位置坐标， 判断 手指的精确触控的位置， 从而进行触控反馈。 该穿戴式触控装置 无需按键也无需触摸屏即可使用户完成触控， 且体积小巧、 便于 携带， 相应的穿戴式触控方法触控准确， 适用面较广。 而釆用的示例性实施方式， 然而本发明并不局限于此。 对于本领 域内的普通技术人员而言， 在不脱离本发明的精神和实质的情况 下， 可以做出各种变型和改进， 这些变型和改进也视为本发明的 保护范围。
