Description

用于移动计算装置的虚拟输入装置的设备
技术领域
本实用新型一般涉及键盘领域，特别涉及用于移动计算装置的虚拟键盘。 
背景技术
在现有技术的美国专利6266048B1中公开的手持式装置的键盘是已知的。美国专利6266048B1中所述的装置包括：从所附个人数字助理投映出的虚拟显示屏和虚拟键盘，其中利用数字微镜显示器（Digital Micro mirror Display），其具有在虚拟键盘上投映的两个激光传感器。由于这种装置的准确性实际主要取决于激光束在所述虚拟键盘的虚拟键上的拦截，因而输入的准确性不很高。 
另一键盘在美国专利6650318B1中公开。所述装置包括：数据输入装置的光学生成影像；传感器，其可操作以传感在至少一个输入区上执行的动作，和处理器，其与传感器通讯而可操作以处理用于执行与至少一个输入区相关联的操作的信号。输入的准确性也主要取决于对从影像轮廓内的对象反射的光的探测。 
另一键盘在美国专利7215327B2中公开。所述装置包括：第一激光发射器，第二激光发射器，和激光接收器。第一激光发射器执行表面扫描，以生成键盘的模式。当用户使用虚拟键盘进入输入状态时，第二激光发射器同时生成第一反射束和第二反射束。最后，激光接收器接收第一反射束和第二反射束，由此获得用户输入的信号。因此，这种输入装置的准确性也主要取决于对反射束的探测。 
另一类型的键盘不依赖于拦截或反射，在美国专利6097373中公开。所述键盘包括：安装在可调头带上的激光笔，用于将准直束引导到由光传感器阵列限定的激光键盘上，激光键盘将由光传感器阵列照明。这种装置对于每项任务都不是舒适和便利的，特别是对于需要速度和准确性的任务而言。 
因此，本发明的目的在于，通过提供用于移动计算装置的虚拟输入装置的方法及其设备而解决上述问题，这样可实现更高的工作效率和准确性，并且对用户而言仍然是经济的和便利的。 
实用新型内容
鉴于前述，本发明提供一种用于移动计算装置的虚拟输出装置的设备，其包括： 
发射器，用于光学地生成一数据输入装置的影像，所述影像包括至少一个输入区域，所述输入区域能够通过用户在该输入区域上执行的动作而致动； 
传感器，其附接到所述用户，用于传感在所述输入上执行的所述动作； 
光学传送器，其联接到所述传感器，具有动力源，用于生成光学信号，所述光学信号对应于所述动作形成的压力和位置； 
光学接收器，其被构造以探测从所述光学传送器生成的所述光学信号并将该信号传送到处理装置以确定所述用户的输入，其中所述对用户的输入的确定基于：所述信号与所述处理装置的记忆单元中存储的至少一种预定信号模式的比较。 
对应的方法具有以下步骤。首先，发射器在工作表面上投映出虚拟输入装置。用户在所述输入区域上执行动作。传感器传感用户在输入区域上执行的动作并通知所联接的光学传送器传送与所述动作形成的压力和位置相对应的光学信号。所述光学信号的强度取决于所述动作形成的压力的水平。光学接收器然后探测该信号并将探测到的信号传送到处理单元，其中对用户输入的确定基于：所述信号与处理装置的记忆单元中存储的至少一个预定信号模式的比较。 
在相关的方面，所述数据输入装置的影像是键盘的影像。所述传感器可以进一步包括多个子传感器，所述子传感器采用指套（finger cover）的形式，以允许用户按照与常规实体键盘上相同的方式打字。优选地，光学接收器被构造为利用常规手机或PDA中的内置相机以实现探测光学信号的目的。 
在一些情况下，所述光学接收器接收多个信号，然后才会处理和确定所述输入，对用户的输入的确定基于多个预定的光学信号模式而定。这将确保所述 输入的准确性达到用户需要的程度。 
为了更好地理解优选实施例并显示出其可如何执行，现在将参照附图以仅示例性方式对其更详细地描述。 
附图说明
图1是图示出根据本实用新型一个实施例的显示出键盘引导结构的装置的示意图。 
图2是根据本实用新型一个实施例的与光学传送器联接的耐磨损传感器的示例。 
图3是用于本实用新型实施例的移动计算装置的输入方法的流程图。 
具体实施方式
同时参见图1、2、3，本实用新型公开一种手机或个人数字助理（PDA）101和耐磨损的指套（finger cover）301。每个套包括传感器302和联接的光学传送器303。位于手机或PDA101上的发射器201投映出虚拟输入键盘或其它输入装置404。 
当用户在投映出的键盘或其它输入区域上执行动作时，传感器302传感该动作并自动通知光学传送器303生成光学信号，所述光学信号对应于该动作形成的压力和位置。光学信号的强度或光强根据所述动作形成的压力的水平而定。光学信号然后由光学接收器401探测，光学接收器401将探测到的信号传送到处理装置501以确定用户输入。所述确定包括：检查信号的有效性601，随后针对在处理装置501的记忆单元中存储的预定信号模式检查所探测到的光学信号的特性602。所述确定的输出显示在手机或PDA101的显示屏102上。 
本领域技术人员应认识到，本实用新型不限于在上文中已具体显示和描述的内容。相反地，本实用新型的范围包括在上文中所述各特征的组合和子组合、以及对于本领域技术人员在阅读以上描述后进行的不在现有技术范围内的对本实用新型的修改和变化。
