Description

用于数据处理系统的可佩戴的信号输入装置
技术领域
本发明涉及信号传输及处理技术，尤其是涉及一种用于数据处理系统的可佩戴的 信号输入装置。 背景技术
通常， 数据处理系统（如台式计算机、 便携式计算机、 服务器、 大型机等）都需 要配备人机交互信号输入输出装置， 如鼠标、键盘、显示屏等。 鼠标诞生于 1964年， 主要用于实现一个 X、 Y轴的位置输入 （有的增加了 Z轴）， 通过和键盘的结合， 加 上显示屏的对光标和字符图形等的显示， 可以方便地完成位置和字符信息的输入。
请参阅图 1， 目前普通的台式计算机包括主机 110、 用于向用户显示各种信息的 显示屏 120、 用于实现信号输入的鼠标 130和键盘 140; 其中， 鼠标 130和键盘 140 可以采用有线或无线方式和主机 110相连。
但是，通过观察计算机使用者使用键盘 140和鼠标 130的过程， 可以发现现有技 术的信号输入装置存在一些缺陷。由于键盘 140和鼠标 130不能很好地在: r起同时工 作， 往往需要使用者的手从键盘 140移开， 找到鼠标 130， 然后进行位移信号输入操 作， 这个移动的距离有近有远； 鼠标 130操作结束后， 需要使用者将手从鼠标 130移 回到键盘 140， 其中需要食指先找到键盘 140的定位键（通常是 F键和 J键)， 或者 直接由眼睛的辅助下， 直接找到按键， 然后才能进行下一步的字符输入操作。在实际 操作中，字符输入和位置输入的切换非常频繁，这就需要使用者的手在键盘 140和鼠 标 130之间频繁切换，但是经常会因为手一下子没有抓到鼠标而导致眼睛不得不离开 屏幕去找鼠标或者按键， 在切换的过程中有个停顿， 从而导致输入的效率下降。
参考图 2，对于笔记本型或便携式计算机来说，键盘 140、鼠标的变形轨迹杆 (Track Point) 150和触摸板 (Touch Panel) 160等都集成在主机 111上。 虽然由于轨迹杆 150直接嵌套在键盘 140中， 从而可以在操作时缩短手移动的距离， 但是由于与轨迹 杆 150配合的两个按键（未标示）距离键盘较远，因此在食指操作轨迹杆 150的时候， 需要大拇指来配合操作按键， 输入效率依然有待提高。触摸板 160距离键盘较远， 切 换时， 需要手指完全从键盘 140上移开才能在触摸板 (Touch Panel) 160上操作， 反之亦然。因此切换效率较轨迹杆 150更低。大部分操作者还是对普通鼠标更加习惯 一些， 所以很多操作者在使用笔记本型电脑的时候， 喜欢外插一个鼠标来使用。不管 釆用何种方式， 现有的方案都会影响到切换效率。
此外， 经过多年的发展， 现有技术中还出现了多种不同形式的鼠标。如中国专利 申请第 02137574.7号公开了一种指戴的压力感应式光学鼠标；中国专利第 02229039.7 号公开了一种将鼠标的滚轮设在指套上由拇指撮动的技术方案： 美国专利第 US 2004012564号公开的技术方案中， 则将 X-Y输入传感器设置在一个类似手套的装置 上；美国专利第 US 2003174124号和第 US 2002101401号的技术方案将鼠标的按键集 中在一个大拇指上， 借助其他手指完成所有的操作； 美国专利第 US 5706026号的公 幵的技术方案中，将按键设置在手指关节上；美国专利第 US 2003038783号的技术方 案则巧妙地将滚轮放置在手掌边， 将按键设在食指和中指上； 德国专利第 DE 10040812号则将鼠标的传感器集中在两个指头上。
但是， 综观以上专利申请或其他类似的专利申请， 都存在一个类似的缺陷： 就是 在设计鼠标的时候，仍然没有和键盘的按键输入操作一起综合考虑， 因此无法有效提 高使用者在鼠标和键盘输入之间进行切换的效率。 例如， 美国专利第 US 2003174124 号和第 US 2002101401号几乎不可能实现切换，因为至少有一个手指的整体被鼠标完 全占据，从而导致该手指不能参加键盘输入；德国专利第 DE 10040812号公开的技术 方案利用在手指头设置指环传感器，指尖部分裸露，还可以进行正常的键盘输入操作， 移开键盘时， 不用另行去找鼠标， 因为鼠标就在指头上。但想避免位置和字符输入的 误操作， 还是要将整只手掌移开键盘， 移到操作台上来进行鼠标的位置输入操作， 其 输入效率也有待改进； 美国专利第 US 5706026号中， 使用者的手只能用作鼠标， 再 用来进行键盘操作时容易引起误操作， 因为在想进行字符输入时，容易产生位置输入 误动作， 导致光标游走偏离原来预定的位置。
一种现有技术的输入装置可以参阅加拿大专利第 CA 2450494号（参照图 3 )。 该 输入装置 200包括位于食指尖的用于产生位移信号的轨迹装置 210; 位于中指和无名 指的用于产生按键信号的压力板 220; 以及用于将位移信号和按键信号传输到计算机 的发射器 230; 还包括位于食指边缘的滚动 /翻页按钮 240。 该现有技术的缺陷在于： 首先， 使用者的手只能用作鼠标， 再用来进行键盘操作时容易引起误操作， 这是因为 在想进行字符输入时， 由于食指在键盘上的移动，轨迹装置 210容易产生位置输入误 动作， 导致光标游走偏离原来预定的位置； 其次， 中指和无名指敲击键盘时， 也容易 使压力板 220产生错误的鼠标按键信号； 再次， 由于传统的鼠标操作中， 使用者已经 习惯釆用食指来操纵左键，用中指来操纵右键；而该专利技术则将压力板设置在中指 和无名指， 会造成使用者的误操作而影响工作效率； 最后， 该专利技术中， 采用设置 在食指边缘的滚动 /翻页按钮 240来实现翻页操作， 也与传统的滚轮工作方式不同， 使用者的操作因不符合习惯而较不便捷。 发明内容
本发明解决的技术问题在于提供一种用于数据处理系统的信号输入装置，可以便 捷地实现和其他输入设备的切换配合， 提高信号输入的效率。
为此，本发明解决技术问题的技术方案是：提供一种用于数据处理系统的可佩戴 的信号输入装置， 包括- 佩戴单元， 至少具有食指套和中指套；

本发明的技术方案是采用非机械接触的方法（比如利用光学、磁场等信息）来感 知位移， 同时利用手指中最灵活的食指和中指来替代目前的鼠标实体， 既可以放在左 手手指上， 也可以放在右手手指上。
请一并参阅图 4和图 5， 本发明信号输入装置包括佩戴单元 310、 位置感知单元 320、 第一按键 330、 第二按键 340、 输入开关单元 350以及信号处理发射部分 400。 位置感知单元 320、 第一按键 330、 第二按键 340、 输入开关单元 350分别通过连线 (未标号） 与信号处理发射部分 400连接。
其中， 所述佩戴单元 310包括食指套 311、 中指套 312和手腕部 313， 采用软性 材料制成， 使得信号输入装置可以方便地佩戴在使用者的操作手上。
所述位置感知单元 320位于所述佩戴单元的食指套 311上，用于采用非机械接触 的方式检测食指的移动并相应产生位置信号； 其可以应用光学扫描的原理，也可以采 用磁场感应的原理来实现，也就是说，可以采用磁感应器件或光扫描感应器件或电容 感应器件。
所述第一和第二按键 330、 340分别位于食指套 311和中指套 312上， 第一按键 330可以替代鼠标的输入左键， 通常作确认、 选中等操作； 第二按键 340则充当鼠标 的输入右键， 通常作取消、释放等操作。所述第一按键 330和第二按键 340可以采用 普通的接触式或感应式按键。
所述输入开关单元 350设置于所述佩戴单元的食指套 311的边缘，并且连接到所 述信号处理发射部分 400， 用于开启和关闭所述信号输入装置。
所述信号处理发射部分 400位于佩戴单元的手腕部 313， 用于处理通过连线传输 过来的数据并发射。
本发明信号输入装置的操作过程是： 当手指头在桌面上或其它平台上移动时，食 指套 311上的位置感知单元 320感知到手指移动， 产生 X-Y轴的相对位移， 传输给 信号处理发射部分 400; 信号处理发射部分 400将位移信号发送给计算机内部的无线 接收装置 910; 所述无线接收装置将信号转发给键盘控制器 920; 键盘控制器 920通 知由中央处理器 930运行的操作系统处理光标位移并在屏幕 940上显示。
当食指敲击第一按键 330时， 信号处理发射部分 400将按键信号发送到计算机； 通常， 第一按键 330作为鼠标的输入左键， 通常作确认， 选中等操作。 当中指敲击第 二按键 340时， 信号处理发射部分 400将按键信号发送到计算机； 通常， 第二按键 340作为鼠标的输入右键， 通常作取消， 释放等操作。
需要进一步说明的是，本发明信号输入装置只有在食指套 311上的信号输入开关 单元 350处在开通的情况下， 才能进行正常的鼠标操作。 在使用完信号输入装置后， 需要关闭该信号输入开关单元 350， 否则容易在手接触到其他表面的时候产生鼠标光 标的误动作， 比如拿杯子喝水的时候、 接听电话的时候等。 该信号输入开关单元 350 可以是切换开关， 即按一下开通信号输入装置， 再按一下关闭信号输入装置， 并且可 以和别的输入设备联动切换， 该信号输入开关单元 350由距离最近的大拇指操作。
请一并参阅图 6和图 7， 根据需要食指套 311内还可以设置一个前后翻滚运动的 翻页单元 360， 作为上下的翻页操作键。
翻页单元 360设置在食指套 311的侧部， 在进行位移操作或左右键操作时，翻页 单元 360悬空， 不会引起翻页单元 360的滚动； 当需要使用翻页单元 360时， 食指稍 微向一边侧倾就可以进行滚轮操作， 当侧倾时， 由于位置感知单元 320偏离桌面从而 自动停止位置感知动作， 这样在进行滚轮操作时， 不会引起鼠标光标的误动作。可以 理解的是，翻页单元 360也可以装在其他手指比如中指上或无名指，这样可以减轻食 指的负担。
为了便于对本发明的理解， 下面结合实施例对本发明进行详细描述 实施例一
请参阅图 8， 在本实施例中， 信号输入装置包括位于手腕部的信号处理发射部分 400和位于手指部分的第一按键 330、信号输入开关单元 350、第二按键 340、翻页单 元 360和位置感知单元 320; 还包括连接这些元件的连线 （未标示）。
所述信号处理发射部分 400包括信号处理单元 410、 信号发射单元 420和电池
430。 所述信号发射单元 420采用无线或红外信号。
所述第一按键 330、 第二按键 340和信号输入开关单元 350可以采用欧姆龙的按 键， 且分别通过连线连接到信号处理单元 410。
所述位置感知单元 320包括发光管 321、 传感器 322和透镜 323。
其中， 透镜 323可以采用安捷伦（Agilent)推荐的 HDNS2100, 给传感器 322照 明用的发光管 321可以采用 HLMPED800-XX000LED。
本实施例中，传感器 322采用目前常用的光电鼠标位移传感器，比如采用 Agilent 的 S2030，可以准确地感知 X-Y的位移，还自带 LED的驱动；无线部分可以采用 Agilent (安捷伦） 的芯片和 ADNS-2030配套的芯片。
因为 Agilent的传统的光电鼠标芯片， 如 S2599都是将传感器（SENSOR)和处 理芯片做在一起， 如果放在指头尖上会显得体积很大。 因此本实施例采用 Agilent的 S2030, 将传感器和处理芯片分开； 将传感器放在指尖上， 处理芯片即手腕上的信号 处理单元 410， 传感器和处理芯片之间用连线连接。
请参阅图 9， 是 Agilent的芯片 ADNS-2030的内部框图。 包括电源输入管脚、 光 源输出管脚、 图像处理单元、 串口输出管脚、 四象限输出管脚、振荡器和上电复位单 元。
在图 9所示芯片的内部框图的基础上， 本实施例采取了一些措施来减小传感器 322的体积； 删除在传感器芯片中四象限输出部分电路， 再删除两个内部参考管脚， 只保留串口输出管脚，这样可以使芯片的管脚总数在九个左右，即电源 Vdd、地 Gnd、 串口输出两个、 震荡器两个、 LED电阻接线脚一个、 LED输出控制一个、 电源控制 脚一个。
请参阅图 10， 本实施例中， 将位于食指套 311的第一按键 330以及发光管 321、 透镜 323也集成在传感器 322芯片的封装中，电阻和晶振放在芯片的上面四周的位置， 中间供食指尖操作。
请参阅图 11和图 12， 翻页单元 360包括滚轮轴 361、滚轮 362、支撑滚轮轴 361 和滚轮 362的支架 363和 364、 圆形的光学编码器 365、 光源 366、 第三按键 367和 线路板 368。基本原理是由滚轮 362因摩擦桌面产生滚动带动滚轮上的通孔 371转动， 当光束通过通孔 371时，光学编码器 365接收到光而产生信号， 当滚轮 362转过一个 角度时， 光源 366被滚轮 362挡住， 由此在光学编码器 365上产生脉冲信号， 微处理 器即可由此脉冲信号的个数及其相位差算出滚轮 360移动的距离或滚动角度及方向。
请参阅图 13， 本实施例中， 为了缩小翻页单元 360及其附件的体积， 将滚轮的 支架 363和编码器 365直接做在一起，翻页单元 360的另一侧支架 364和光源 366做 在一起， 支架 363和 364上方幵口， 适合滚轮轴 361卡入， ·既能灵活转动， 也不会轻 易脱出。
请参阅图 14， 计算机内的无线接收装置 910包括无线接收电路 911、 转换器 912 和计算机键盘接口 913 ; 其中， 转换器可以采用 CYPRESS CY7C63723A-PC。
工作时， 传感器 322会自动监控发光管 321的工作，在传感器 322没有检测到位 移时， 发光管 321处在低亮度工作状态， 当有位移发生时， 传感器 322触发发光管 321高亮， 会去照亮其所在的表面， 传感器 322会每隔一定时间做一次扫描， 然后由 信号处理单元 410对两次扫描的图像进行比较，从而得出信号输入装置移动的方向和 速度。 毫无疑问， 如果扫描信号频率越高， 那么信号输入装置对于运动的表现能力将 越细腻，尤其在做变速运动时的反应更为明显。当手指停止移动或离开反射表面一定 距离后， 传感器 322不能感知到位移时， 自动控制发光管 321处在低亮状态， 这样比 较省电， 也可以延长器件的寿命。
一般来说，每移动一英寸，就向电脑传回 400次坐标值。因此其精度是相当高的。 由于不再是通过机械摩擦而产生移动数据， 因此， 摆脱了操作面的约束， 可以在几乎 所有的操作面上使用， 比如腿上、 床上等等， 没有机械磨损， 寿命也有很大提高。
实施例二
请参阅图 13， 实施例二与实施例一大致相同， 不同之处在于： 在实施例二中， 翻页单元 360设置在佩戴单元的中指套 312上； 同时导致接线的安排有所不同， 食指 套 311总共有三根线（一根接地、一根第一按键、一根开关。）， 中指套 312总共七根 线 （分别是一根第二按键和六根翻页单元）。 所述六根翻页单元线包括接地、 第三按 键、 光源、 编码 A、 电源、 编码 B。
和实施例一类似，在中指套 312上的翻页单元 360也有一定的倾斜角，在平时做 按键操作时， 不会碰到， 只有在中指微微倾斜时， 才会让滚轮 362碰到桌面进行上下 滚轮操作。
本实施例二的优点在于： 由于食指承担移动鼠标和点击左键的作用， 中指承担上 下滚动和点击右键的作用。这样可以减轻食指的工作量，使得食指和中指的工作量稍 稍平均一些， 有利于提高工作效率。 因为如果翻页单元 360也设置在食指套 311上， 那么鼠标的移动、左键点击、上下翻滚这三大功能都集中在食指上， 工作量太大。 当 然， 想要减轻食指的工作量， 就需要牺牲习惯的继承性， 即需要使用者改变一定的使 用习惯， 按照目前的鼠标使用传统， 滚轮设置在鼠标的中间位置， 一般使用食指来操 作， 现在改为中指略微有些不习惯。
实施例三
.请参阅图 14， 本实施例中， 将发光管 321、透镜 323和传感器 322集成在手腕部 分。 位移感知单元中增加两根光纤 324， 一根作光源， 一根做信号回传， 两根光纤放 置在食指上， 并连到手腕上。 .
工作时，光纤 324将发光管 321上的光束引到手指头尖上，再将桌面反射的信号 经过光纤 324传回到芯片的传感器 322中。
请参阅图 15， 为了增加聚光， 还可以在食指套 311设置一个透镜 325。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人 员来说， 在不脱离本发明原理的前提下， 还可以作出若干改进和润饰， 这些改进和润 饰也应视为本发明的保护范围。
