具体实施方式
为更进一步阐述本公开所采取的技术手段及功效，以下结合附图及实施例，对依据本公开提出的电子设备其具体实施方式、结构、特征及其功效，详细说明如后。
相关技术中的触控笔是一种需要配合触控面板使用的电子设备，由于触控笔无法单独使用，因此触控笔的使用灵活性较低。本公开实施例提供了一种电子设备，该电子设备无需配合其他设备使用，所以该电子设备的使用灵活性较高。
示例地，图1为本公开实施例提供的一种电子设备的结构示意图，如图1所示，该电子设备可以包括：本体1、发光组件2、感光组件3和处理器4。发光组件2、感光组件3和处理器4均位于本体1上，感光组件3与处理器4连接。其中，发光组件2用于发出探测光；感光组件3用于在接收到该探测光的反射光后，获取反射光的光学信息；处理器4用于根据光学信息确定发光组件2的运动轨迹。
综上所述，本公开实施例提供的电子设备中，感光组件能够在接收到发光组件发出的探测光的反射光后，获取该反射光的光学信息，并且处理器能够根据感光组件获取到的光学信息确定发光组件的运动轨迹。这样一来，电子设备 就实现了通过自身的处理器获取发光组件的运动轨迹，并且，在电子设备获取该运动轨迹的过程中，无需借助其他设备，因此，提升了电子设备的使用灵活性。
本公开实施例提供的电子设备中本体的形状可以是任意形状，图1中以本体1呈笔状为例，当然该本体1也可以呈其他形状(如手电筒状、手表状等)。电子设备中的发光组件2可以位于本体1的任意位置，例如，当电子设备中的本体1呈笔状时，本体1包括笔杆011，发光组件2可以位于笔杆011的笔尖，此时，电子设备相当于智能笔，电子设备中发光组件2的运动轨迹相当于智能笔的书写轨迹。
在电子设备获取该运动轨迹的过程中，发光组件2还可以起到照明的作用，从而避免了因亮度不够导致处理器4无法获取到的发光组件2的运动轨迹的情况发生。
用户在使用电子设备时，用户可以手握本体1并带动本体1移动，使得本体1上的发光组件2移动。此时，发光组件2所发出的探测光的照射区域也会移动，感光组件3获取的光学信息会发生改变，处理器4能够根据改变的光学信息确定发光组件2的运动轨迹。
可选地，感光组件3获取到的光学信息包括：n次获取到的反射光的n个图像，n≥2。也即是，感光组件3可以连续n次获取反射光的图像，得到上述n个图像。可选地，感光组件3每相邻两次获取反射光的图像的时间间隔可以为固定间隔，当然，该时间间隔也可以不是固定间隔，本公开实施例对此不作限定。
在上述光学信息包括上述n个图像时，处理器4可以根据该n个图像确定发光组件2的运动轨迹。此时，处理器4可以用于：首先，确定这n个图像中第i个图像的第一特征区域，以及第i+1个图像的第二特征区域；然后，根据第一特征区域在第i个图像中的方位，以及第二特征区域在第i+1个图像中的方位，确定第i个图像对应的发光组件的子轨迹；最后，根据n个图像中前n-1个图像对应的子轨迹，确定运动轨迹。其中，1≤i＜n，第一特征区域和第二特征区域的相似度大于相似度阈值。该相似度阈值可以是任意的相似度，如90％或100％等。
示例地，在用户使用电子设备的过程中，用户可以手持电子设备移动，以使发光组件移动。假设在这一过程中，感光组件获取到的n个图像中的第i个图 像包括图2中区域a和区域b组成的圆形图像，该n个图像中的第i+1个图像包括图2中区域b和区域c组成的圆形图像。那么，处理器可以比较该第i个图像和第i+1个图像，以确定这两个图像中相似度大于阈值的两个特征区域，分别为第i个图像中的第一特征区域(如图2中的区域b)，以及第i+1个图像中的第二特征区域(如图2中的区域b)。根据图2可知，第一特征区域在第i个图像中的方位为右侧方位，第二特征区域在第i+1个图像中的方位为左侧方位，处理器比较这两个方位可知，在感光组件获取这两个图像的过程中，发光组件进行了从左到右的移动，进而可以得到发光组件在感光组件获取这两个图像的过程中的子轨迹(可以称为第i个图像对应的子轨迹)。该子轨迹可以是从第i个图像对应的光照区域(探测光的照射区域)的中心到第i+1个图像对应的光照区域的中心的轨迹。
在得到n个图像中前n-1个图像对应的子轨迹之后，处理器能够将这前n-1个图像对应的子轨迹进行拼接，以得到在感光组件获取n个图像的过程中发光组件的运动轨迹。例如，假设感光组件获取到的n个图像如图3所示的5个圆形图像，处理器在得到前4个图像对应的4个子轨迹(如图3中的子轨迹1、2、3和4)后，可以依次将这4个子轨迹进行拼接，从而得到子轨迹1、2、3和4组成的发光组件的运动轨迹。
进一步地，上述光学信息不仅可以包括上述n个图像，还可以包括：上述n个图像中第1个图像对应的反射光的波长、反射角和光强中的至少一种信息(也即在感光组件获取该第1个图像时，反射光的该至少一种信息)。此时，处理器在根据上述n个图像确定发光组件2的运动轨迹前，可以根据该至少一种信息对这n个图像中的后n-1个图像进行校正，以使后n-1个图像对应的该至少一种信息与第1个图像对应的该至少一种信息较为相似，从而避免外部环境的影响导致后n-1个图像对应的该至少一种信息相对第1个图像对应的该至少一种信息出现较大偏移，避免后n-1个图像受外部环境的影响而较不准确。
可选地，图4为本公开实施例提供的一种电子设备的结构框图。如图4所示，在光学信息包括上述反射光的图像时，感光组件3包括：用于获取反射光的图像的成像组件34(如微成像器)。在光学信息包括第1个图像对应的反射光的波长时，感光组件3包括：波长获取组件31，波长获取组件31用于获取反射光的波长；在光学信息包括第1个图像对应的反射光的反射角时，感光组件3包括：反射角获取组件32，反射角获取组件32用于获取反射光的反射角；在光 学信息包括第1个图像对应的反射光的光强时，感光组件3包括：光强获取组件33，光强获取组件33用于获取反射光的光强。成像组件34、波长获取组件31、反射角获取组件32和光强获取组件33均与处理器4连接。
可选地，如图4所示，该电子设备还可以包括：位于本体(图4中未示出)上的存储器5，存储器5与处理器4连接，存储器5用于存储处理器4得到的运动轨迹。由于存储器5能够对处理器4得到的运动轨迹进行记录，因此，实现了电子设备自行记录发光组件2的运动轨迹的效果。示例地，处理器4能够将得到的运动轨迹转化为图片，然后，存储器5对图片进行存储。又示例地，处理器4还能够将得到的运动轨迹转化成文档，然后存储器5对该文档进行存储。
可选地，该电子设备还可以包括：位于本体上的保存按钮(图4中未示出)，用户可以通过按压保存按钮触发存储器5对运动轨迹进行存储。本体上还可以设置有指示灯(图4中未示出)，指示灯可以在存储器5成功存储运动轨迹后闪烁，以提醒用户成功保存运动轨迹。
在本公开实施例中，发光组件3可以是任一种能够发光的组件，如用于发出激光、红外光等的组件。处理器4可以是任一种处理器，如数字信号处理器(digital signal processor，DSP)等。存储器5可以为任一种存储器，如安全数码卡(Secure Digital Memory Card，SD卡)等。
可选地，感光组件3获取光学信息可以是自发的操作，当然也可以是在处理器4的控制下的操作，此时，处理器4还用于控制感光组件3获取上述光学信息。
可选地，该电子设备还可以包括：位于本体上的发光控制组件。该发光控制组件能够与发光组件2连接(可以是直接连接，也可以是间接连接)，发光控制组件用于控制发光组件2发出探测光。用户可以通过控制该发光控制组件控制发光组件2发出探测光。示例地，请继续参考图4，该发光控制组件可以包括：位于本体1上的压力传感区域的压力传感器6。该压力传感器6用于在压力传感区域所受压力大于压力阈值时，控制发光组件2发出探测光。图5为本公开实施例提供的另一种电子设备的结构示意图，如图5所示，为了直观的看到压力传感器的位置，可以在本体1上的压力传感区域设置一能够按压的开关14，开关14内设置有压力传感器(图5中未示出)。开关14突出于本体1的表面，方便用户对开关14进行按压，当用户按压开关14时，压力传感器能够检测到压力传感区域受到的压力。
本公开实施例提供的电子设备中的本体可以包括笔杆，用户可以像握笔一样使用电子设备。用户在握笔杆时，本体上被手接触的区域可以为上述压力传感区域。以用户写字为例，用户每写完一个字时，会抬起笔以便进行下一个字的书写，在用户抬笔时，用户握笔的力量会发生变化，笔受到的压力会减小，此时，位于压力传感区域的压力传感器能够检测到压力变小，当压力传感器检测到的压力小于压力阈值时，便控制发光组件不再发出探测光，这样就能够保证用户在书写两个字之间的笔尖抬起时间段内，处理器不会生成运动轨迹，相应地存储器也不会记录运动轨迹。
设定在每次压力传感器检测到的压力大于压力阈值期间，存储器记录的运动轨迹为一节轨迹。不同节的轨迹存储在存储器中的不同位置，以免不同节的轨迹重复导致记录的运动轨迹混乱。此时压力传感器可以作为开启记录功能的开关。用户在使用电子设备时，可以握住电子设备的本体，此时压力传感器检测到的压力大于压力阈值，发光组件、感光组件、处理器和存储器均开始工作，存储器开始记录这段时间内处理器确定出的发光组件的运动轨迹。用户在用该电子设备书写结束后，可以轻轻松开电子设备的本体，此时压力传感器检测到的压力小于压力阈值，存储器便可结束本节运动轨迹的记录。电子设备中还可以设置有数据连接端口，通过数据连接端口可以将存储器中记录的运动轨迹传输到其他设备上。
本公开实施例中以发光控制组件包括压力传感器为例，可选地，该发光控制组件还可以包括位于本体1上的启动开关(说明书附图中未示出)，启动开关与发光组件2连接，发光组件2发光的前提条件需要包括：启动开关开启。
本公开实施例中以发光控制组件能够直接控制发光组件发光为例，可选地，发光控制组件也可以通过处理器控制发光组件发光。示例地，在压力传感器检测到的压力大于压力阈值时，处理器可以控制发光组件发光，本公开实施例对此不作限定。
可选地，处理器4也可以在发光控制组件的控制下进行运动轨迹的确定。比如，当压力传感器检测到的压力小于压力阈值时，处理器4便不确定发光组件2的运动轨迹。此时即便是发光组件2可以发出探测光，且感光组件获取到反射光的光学信息，处理器4也不会计算上述运动轨迹。
可选地，如图4所示，电子设备还包括：位于本体上的光强传感器7；该光强传感器7与处理器4连接；光强传感器7用于检测反射光的光强；处理器4 用于在光强传感器7检测到的光强大于光强阈值时确定上述发光组件2的运动轨迹。示例地，当发光组件2置于书写面(如桌面、纸面、人的大腿表面等)上时，光强传感器7检测到的光强较大；当发光组件2悬空时，由于反射面距离光强传感器7较远，光强传感器7检测到的光强较弱；因而可以通过检测光强来检测发光组件2是否置于书写面上，并且，仅在发光组件2置于书写面上进行书写时，处理器4才进行运动轨迹的确定。当用户采用电子设备在书写面上书写，且切换到下一行或下一个字的过程中，由于用户会将手抬起，使得光强传感器7检测到的反射光的光强小于光强阈值，因此，在此过程中处理器不会确定发光组件的运动轨迹，相应地存储器也不会记录该运动轨迹。
可选地，请继续参考图4，电子设备还包括：投影组件8。投影组件8与处理器4连接，投影组件8用于投影发光组件2的运动轨迹。用户在使用电子设备进行书写时，电子设备中的投影组件8可以将发光组件2的运动轨迹实时的投影出来，方便用户对自己书写情况进行观察，出现错误可以及时更改，或者可以再次书写。
可选地，投影组件8投影运动轨迹可以是自发的操作，也可以是在处理器4的控制下进行的操作。当投影组件8投影运动轨迹是在处理器4的控制下进行的时，可以在本体上设置投影按钮，按下投影按钮时，处理器4能够接收到投影指令，此时处理器4控制投影组件8投影。
可选地，在处理器4控制投影组件8投影运动轨迹的情况下，处理器4可以在用户每写完一节运动轨迹(处理器确定出一节运动轨迹)再控制投影组件8对其进行投影，也可以是处理器4控制投影组件8对运动轨迹进行实时地投影。例如，用户要记录A、B、C……G，其中每个字母代表一节运动轨迹，其投影方法有多种，在此简单的介绍三种投影方法。第一种，用户在进行书写时就已经进行投影，即对运动轨迹进行实时投影，用户可以随时观察到自己的书写状况。第二种，如在用户书写G时，可以将之前书写的有A至F全部投影，待书写完G时，再将G投影，书写G的期间不对G进行投影。第三种，在用户书写完G时，仅仅对G进行投影，而A至F不会对其投影。
可选地，在存储器成功存储运动轨迹后，投影组件8可以投影预定时长以提醒用户存储成功，同时用户还可以通过该投影检查刚才的书写情况。
图5为本公开实施例提供的另一种电子设备的外观示意图。请参考图5，本体1可以包括：笔杆011和笔帽012，笔帽012与笔杆011上设置有笔尖的一端 (如图5中发光组件2所在的一端)可拆卸连接，笔帽012能够对笔尖处的发光组件2进行保护，防止发光组件2被损坏。用户在使用电子设备时，如图6所示，为了防止笔帽012的丢失还可以将笔帽012安装在笔杆011中笔尖所在端的对端。用户在无需使用电子设备时，如图7所示，可以将笔帽012安装在笔杆011中笔尖所在的一端。投影组件8可以位于笔帽012上。上述处理器4、发光组件2、感光组件3、存储器(图5中未示出)、发光控制组件(图5中未示出)、光强传感器(图5中未示出)均可以位于笔杆011上。当用户使用电子设备进行书写时，用户可以手握笔杆011，并将笔帽012放置在旁边，使得投影组件8投影的画面投影在某平面上，这样用户便可以一边书写一边观看自己的书写结果。
可选地，笔帽012上可以设置有接收器(说明书附图中未示出)，用于接收运动轨迹。同时，笔杆011上还设置有发送器(说明书附图中未示出)，发送器与处理器4连接，接收器与投影组件8连接。处理器4可以控制发送器向接收器发送运动轨迹，接收器接收到运动轨迹后可以向投影组件8发送该运动轨迹，以便于投影组件8对该运动轨迹进行投影。
可选地，请参考图5，电子设备还包括：电源10，电源10用于向电子设备中的至少部分用电组件供电。电子设备中的用电组件可以包括：电子设备中除电源10之外的组件中需要用电的组件，如上述处理器4、发光组件2、投影组件8等，电子设备中的电源10可以向全部的用电组件供电，也可以仅向部分用电组件供电，本公开实施例对此不作限定。
可选地，电源10用于在笔帽012安装于笔杆011中笔尖所在端的对端时(如图6所示)，向上述至少部分用电组件供电。可见，只有将笔帽012安装在笔杆011中笔尖所在端的对端时，电源才能向该至少部分用电组件供电，整个电子设备才能正常使用，进而能够避免笔帽012的丢失。
示例地，图8为本公开实施例提供的一种电源的供电示意图，如图8所示，电子设备还包括：第一端口021、第二端口022、第三端口023和第四端口024，这些端口也称为接口；第一端口021、电源10和第二端口022均可以位于笔杆011上，且第一端口021、电源10和第二端口022串连；第三端口023和第四端口024均位于笔帽012上，且第三端口023和第四端口024连接。在笔帽012安装于笔杆011中笔尖所在端的对端时，第一端口021与第三端口023对接，第二端口022与第四端口024对接，第一端口021、电源10、第二端口022、第 四端口024和第三端口023形成供电回路。电源10用于供电的上述至少部分用电组件(图8中未示出)可以串连在该供电回路上。其中，第一端口021与第三端口023可以采用触碰式通电，第二端口022和第四端口024也可以采用触碰式通电。第一端口021、第二端口022、第三端口023和第四端口024均可以为陶瓷通电接口。
