Description

触控笔、触控装置及测量触控笔倾角的方法 技术领域
本发明涉及触控装置，尤其涉及一种能够测量相对于触控面板的倾角的触控笔、触控装置和测量触控笔倾角的方法。
背景技术
随着信息技术的发展，诸如便携式移动设备的电子设备与人们的生活越发密切相关。这种便携式移动设备可以接收用户的输入，并根据该输入来执行用户期望的功能。作为接收用户输入的输入装置，触控装置以其体积小、重量轻、易于操作的优点而被广泛使用。
触控装置主要分为两种，电阻式触控装置和电容式触控装置。电阻式触控装置成本低、易于制造，但是只能支持单指操作。电容式触控装置的可操作性较强、支持多指功能，因而成为目前触控装置的首选。
电容触控装置包括电容触控面板，电容触控面板可以通过分布于其上的正交电容图形来感知手指(或触笔)触控引起的电容变化，从而测量触控位置和触控强度。电容触控面板可以是位于电容触控装置前面的透明面板，也可以是不透明的人机交互板。
由于能被触控面板感知的导电体需要较大的接触面积，所以会造成定位不准的问题，同时对笔的支持一直不是非常理想。因此，人们期待电容触控装置能支持笔的书写，至少包括纤细笔头、悬空感应、精准定位、压感精确等功能，尤其是在某些绘画应用中需要触控笔相对于触控面板的倾角，从而进行特效绘画，例如喷射效果。
发明内容

具体实施方式
本发明某些实施例于后方将参照所附附图做更全面性地描述，其中一些但并非全部的实施例将被示出。实际上，本发明的各种实施例可以许多不同形式实现，而不应被解释为限于此数所阐述的实施例；相对地，提供这些实施例使得本发明满足适用的法律要求。
为使本领域技术人员更好地理解本发明的技术方案，下面先简单介绍一下触控笔与触控面板的工作原理，图1为触控笔与触控面板的工作原理的示意图，本发明以电容触控面板为例，如图1所示，触控装置包括：触控面板，其上配置有相互正交的用于收发信号的平行电容极板；发送电容极板，其设置在所述面板上，用于向外发送探测波；触控笔，其通过笔头接收面板发送的同步及命令信息，再通过笔头向所述面板发送信号波；接收电容极板，其设置在所述面板上，用于接收所述发送电容极板的探测波和所述笔的信号波；模拟信号处理单元，其根据控制处理单元选择的电容极板来发送相应波形，或者预处理来自接收电容极板的信号；控制处理单元，其将预处理后的接收信号通过AD转换为数字信号，并通过处理得到触控位置，在笔为电容笔的情况下得到笔的位置以及笔回传的信息。
下面结合附图和具体实施方式对本发明提供的触控笔和测量倾角的方法进行详细描述。在这些附图中，对于相同或者相当的构成要素，标注相同标号。以下仅为本发明的触控笔和测量倾角的方法的最佳实施方式，本发明并不仅限于下述结构。本发明一实施例提供一种触控笔及包括该触控笔的触控装置，图2示出了本发明一实施例的触控装置的示意图，参照图2，本发明的触控装置包括触控笔10和触控面板20。下面主要对触控笔10进行详细说明。
图3示出了本实施例的触控笔的结构框图。
如图3所示，本发明的触控笔10包括：笔杆100；笔尖102，笔尖102包括至少部分位于笔杆100内部的第一部分1020和与第一部分相连的第二部分1022；屏蔽单元104，其包围笔尖102的第一部分1020以屏蔽第一部分1020与触控面板之间的通信；以及控制单元108，其用于使能/禁能屏蔽单元104。
图3中，控制单元108设置在笔杆100内，在其他实施例中控制单元108亦可以设置在笔杆100表面等其他位置。
在图3中，第一部分1020的一部分位于笔杆100的内部，但是在其他实施例中，第一部分1020也可以全部位于笔杆100的内部，第二部分1022的一部分也可以位于笔杆100的内部。
在触控笔10与触控面板20的每个通信周期内，触控面板20向触控笔10发送切换命令，触控笔10的控制单元108根据切换命令使能/禁能屏蔽单元104。触控面板20分别获取第一部分1020被屏蔽的状态和未被屏蔽的状态下笔尖102在触控面板20上的投影的重心，通过比较重心的偏移，获得触控笔10相对于触控面板20的倾角。
下面结合图4详细说明本实施例中触控笔10笔尖的结构。
图4示出了本实施例的触控笔的笔尖的示意图。
如图4所示，第一部分1020和第二部分1022优选均为圆柱形。第一部分1020的长度L1大于第二部分1022的长度L2。并且，第一部分1020的直径大于第二部分1022的直径。例如，第一部分1020的直径为约4.5mm，第二部分1022的直径为约1.5mm。
另外，尽管未示出，在本发明的其他实施例中，第一部分1020可以为圆柱形，第二部分1022可以为圆锥形。并且，第一部分1020的直径大于等于第二部分1022的最大直径。
另外，尽管未示出，在本发明的其他实施例中，第一部分1020可以为圆台形，第二部分1022可以为圆锥形。并且，第一部分1020的最小直径大于等于第二部分1022的最大直径。
以下结合图5说明本实施例的触控笔的屏蔽单元的工作原理。
图5A和图5B示出了本实施例的触控笔的屏蔽单元的工作原理。为 方便起见，图5A和图5B中并未示出笔杆100。
如图5A所示，屏蔽单元104是包围第一部分1020的金属套筒。第二部分1022并未被屏蔽单元104包围。
在图5A和图5B中，触控笔10还包括连接屏蔽单元104与地的开关106，控制单元108通过对开关106进行控制来使能/禁能屏蔽单元104。
屏蔽单元104连接至开关106的一端，开关106的另一端接地。在图5A的状态下，屏蔽单元104的屏蔽作用被使能，笔尖的第一部分1020无法与触控面板20进行电容耦合，仅第二部分1022与触控面板20进行电容耦合。
如图5B所示，开关106断开屏蔽单元104与地之间的连接。在图5B的状态下，屏蔽单元104的屏蔽作用被禁能，笔尖的第一部分1020与第二部分1022一起与触控面板20进行电容耦合。
另外，虽然图5A和5B中屏蔽单元104被示为金属套筒，但是在本发明的其他实施例中，屏蔽单元104也可以是包围第一部分1020的金属弹簧。
虽然在图5A和5B中，通过连接屏蔽单元104与地的开关106来使能/禁能屏蔽单元104。但是应该注意，在本发明其他实施例中，控制单元108的IO端口可以直接连接至屏蔽单元104，并且控制单元108通过控制IO端口的输出电压或输出阻抗来使能/禁能屏蔽单元104。例如，控制单元108通过将IO端口接地或设置为高阻抗来使能屏蔽单元104。
本发明另一实施例提供一种测量触控笔倾角的方法。
首先，说明本实施例中的测量触控笔与触控面板之间的倾角的原理。
如图6所示，触控面板20的书写平面为x0y平面，触控笔10与触控面板20的接触点为坐标原点0。当触控笔10在触控面板20上书写时，触控笔10一般会处于图6所示的倾斜状态。
为了确定触控笔10与触控面板20之间的倾角，需要确定触控笔10相对于触控面板20的x轴和y轴的倾角。
参照图7A，触控笔10在x0z平面的投影Pxz与x轴的夹角即为触控笔10相对于触控面板20的x轴的倾角θx。
参照图7B，触控笔10在y0z平面的投影Pyz与y轴的夹角即为触控 笔10相对于触控面板20的y轴的倾角θy。
触控面板20上分布有沿x轴分布的多个电极70和沿y轴分布的多个电极72，如图8所示。当触控笔10在触控面板20上书写时，触控面板20通过电极70和72能够检测到笔尖102的重心的投影在触控面板20上的位置74。
这是因为，笔尖102发送高压交流信号，触控面板20通过与笔尖102发生电容耦合的各个电极70和72就能侦测到笔尖102发送的信号，通过这些电极上信号的重心分布就能检测到笔尖102的位置。
如上所述，本发明的触控笔10的笔尖102具有第一部分1020和第二部分1022，第一部分1020的长度大于第二部分1020的长度，并且第一部分1020的直径大于第二部分1020的直径，且每个通信周期内第一部分1020在被屏蔽单元104屏蔽及未屏蔽两种状态之间切换。在这种情况下，若触控笔倾斜，则笔尖102投影到触控面板20的重心会明显偏移，下面参照图9A和9B进行说明。
图9A示出了本发明的触控笔10没有发生倾斜的状态。在这种状态下，此时，无论笔尖102的第一部分1020是否被屏蔽单元104屏蔽，笔尖102在触控面板20上的投影重心P均位于笔尖102的正下方。
图9B示出了触控笔10发生倾斜的状态，也就是用户使用触控笔10进行书写等操作的状态。在这种状态下，当笔尖102的第一部分1020是被屏蔽单元104屏蔽时，仅笔尖102的第二部分1022与触控面板20进行电容耦合，由于第二部分1022长度较短，此时笔尖102在触控面板20上的投影重心相较于触控笔未倾斜状态下的投影重心P偏移很小，基本上可以忽略，可以认为此时笔尖102在触控面板20上的投影重心即为P，当笔尖102的第一部分1020未被屏蔽单元104屏蔽时，笔尖102的第一部分1020及第二部分1022均与触控面板20进行电容耦合，笔尖102在触控面板20上的投影重心为P′，可见P′相对于P发生了偏移。为了进行比较，图9B中也示出了投影重心P。
正是因为本发明的触控笔10的笔尖102具有以上参照图3-4所描述的结构，所以在触控笔10发生倾斜时，投影重心P′相对于P的偏移明显，可以被触控面板20容易地检测到。
由于本发明的触控笔10采用了屏蔽单元104和控制单元108，所以能够在触控笔10与触控面板20之间的每个通信周期内，先屏蔽掉笔尖102的第一部分1020与触控面板20之间的电容耦合，获得笔尖102的投影重心P，然后使第一部分1020能够与触控面板20之间发生电容耦合，获得笔尖102的投影重心P′。触控面板20通过比较两个重心的偏移，可以获得触控笔10相对于触控面板20的倾角。以下，结合图10具体说明本发明的测量倾角的方法。应当注意，以下步骤是在触控笔10与触控面板20之间的每个通信周期内执行的，通过不断地重复执行这些步骤，触控面板20可以持续地随时获得触控笔10的倾角参数。
在步骤S1000，触控面板20向触控笔10发送使能切换命令。
在步骤S1002，触控笔10的控制单元108根据使能切换命令使能屏蔽单元104。例如，开关106接通，从而将金属套筒104接地。
在步骤S1004，触控面板20获取笔尖102在触控面板20上的投影的重心P。例如，参照图9A，获取投影重心P的坐标(x1，y1)。
在步骤S1006，触控面板20向触控笔10发送禁能切换命令。
在步骤S1008，触控笔10的控制单元108根据禁能切换命令禁能屏蔽单元104。例如，开关106断开，从而使金属套筒104不接地。
在步骤S1010，触控面板20获取笔尖102在触控面板20上的投影的重心P′。例如，参照图9B，获取投影重心P′的坐标(x2，y2)。
在步骤S1012，触控面板20通过比较计算出重心的偏移。
在步骤S1014，触控面板20通过查询预先存储的偏移-角度映射表，获得触控笔10相对于触控面板20的倾角。
尽管上述步骤中先获取屏蔽单元104使能时笔尖的投影重心，后获取屏蔽单元104禁能时笔尖的投影重心，本领域技术人员可以理解的是，同样可以先使得屏蔽单元104禁能，获取屏蔽单元104禁能时笔尖的投影重心，而后使得屏蔽单元104使能，获取屏蔽单元104使能时笔尖的投影重心。
参照图11，在步骤S1004和S1010获取的笔尖102相对于触控面板20的投影重心坐标分别为(x1，y1)和(x2，y2)，根据参照图6-7所述的几何关系，触控笔10相对触控面板20的x轴的倾角与差值(x2-x1)成比例关 系，相对触控面板20的y轴的倾角与差值(y2-y1)成比例关系。
因此，可以预先测量多个规定角度下的坐标差值(x2-x1)和(y2-y1)，由此得到重心偏移-倾角映射表。在步骤S1014中，触控面板20通过查询该重心偏移-倾角映射表，可以快速地获得触控笔10相对于触控面板20的倾角。
另选的是，可以预先测量多个规定角度下的坐标差值(x2-x1)和(y2-y1)，由此拟合出重心偏移与倾角的对应函数关系。在步骤S1014中，针对测量出的坐标差值(x2-x1)和(y2-y1)，可以通过代入对应函数，获得触控笔10相对于触控面板20的倾角。
另外，在屏蔽单元104是金属制成的金属套筒的情况下，参照图12所示，金属套筒可以在顶面上设置开口1040，笔尖102的后端从该开口伸出后与压感传感器接触。
利用本发明的触控装置和测量触控笔倾角的方法，用户可以在触控面板上进行基于倾角的操作，从而实现一些特效，例如，软笔书法、画图类应用中的喷涂等，扩大了触控装置的应用范围。
