本申请要求于2021年06月29日提交中国专利局、申请号为202110726723.X、申请名称为“手写笔检测方法、装置及终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及计算机技术领域，尤其涉及一种手写笔检测方法及终端设备。
背景技术
手写笔是平板电脑等可以通过触控式输入的终端设备进行信息输入及操作的常用电子产品。用户利用手写笔可以在终端设备上进行文字、图形等的输入。用户先移动手写笔使其吸附到终端设备上之后，再拿起手写笔进行使用。而由于手写笔是利用磁力吸附固定到终端设备上的，相关技术中终端设备通过磁场强度确定手写笔是否吸附，存在对手写笔的吸附检测的判断不准确、甚至会误判断的问题。
发明内容
有鉴于此，提出了一种手写笔检测方法、装置及终端设备。
第一方面，本申请的实施例提供了一种手写笔检测方法，应用于终端设备，所述终端设备上设置有用于吸附手写笔的第一区域，所述手写笔的内部设置有用于将所述手写笔吸附固定在所述第一区域的磁力吸附部件，所述方法包括：
在检测到所述第一区域吸附固定有吸附对象的情况下，对所述吸附对象进行检测，得到检测结果，所述检测包括检测所述吸附对象的吸附位置是否准确；

根据第一方面，能快速、准确地检测到第一区域吸附固定有吸附对象的情况下，对第一区域吸附的吸附对象进行检测，并在检测结果为目标检测结果的情况下发出用于提醒用户吸附位置不准确的第一提示和/或用于提醒用户手写笔的正确吸附位置的第二提示。
在一种可能的实现方式中，所述检测还包括检测所述吸附对象是否为手写笔，所述目标检测结果还包括所述吸附对象为手写笔。
这样，可以在吸附对象为手写笔且吸附对象的吸附位置不准确的情况下发出第一提示和/或第二提示，使得手写笔检测的准确性更高。
在一种可能的实现方式中，所述检测包括第一检测步骤和第二检测步骤，所述第一检测步骤用于检测所述吸附对象是否为手写笔，所述第二检测步骤用于检测所述吸附对象的吸附位置是否准确。这样，可以不限定第一检测步骤和第二检测步骤之间的执行顺序，仅以目标检测结果是否达到为基准，可以提高手写笔检测的效率。
在一种可能的实现方式中，所述第二检测步骤在所述第一检测步骤的第一检测结果为所述吸附对象为手写笔的情况下执行。这样，在确定吸附对象为手写笔之后，再执行第二检测步骤，可以减少终端设备所执行的操作，节省终端设备的处理器资源。
在一种可能的实现方式中，所述第一检测步骤，包括：向所述吸附对象发送私有消息，并监听所述吸附对象响应于所述私有消息返回的私有回复消息；其中，所述吸附对象为手写笔，包括：在发出所述私有消息后的第一预设时间内接收到所述私有回复消息。这样，可以提高吸附对象是否为手写笔检测的准确性。
在一种可能的实现方式中，所述第二检测步骤，包括：向所述吸附对象发送连接诊断消息，并监听所述吸附对象响应于所述连接诊断消息返回的诊断回复消息，所述连接诊断消息包括无线充电协议消息；其中，所述吸附对象的吸附位置不准确，包括：在发出所述连接诊断消息后的第二预设时间内未接收到所述诊断回复消息。这样，可以简化为检测吸附对象的吸附位置是否准确终端设备所需执行的操作。
在一种可能的实现方式中，所述私有消息还用于获取所述吸附对象的第一位置信息，所述私有回复消息包括所述吸附对象的第一位置信息；
其中，向所述吸附对象发送连接诊断消息，包括：

这样，由于第一位置信息可以指示吸附对象的实际空间位置，进而基于确定的吸附对象与所述终端设备之间的相对位置关系可以提高手写笔检测的准确性。
在一种可能的实现方式中，发出第一提示包括以下至少一种操作：
在所述终端设备的显示屏中显示所述第一提示；
以对应于所述第一提示的方式进行震动；

这样，可以通过各种可能的方式提醒用户，以使得用户可以及时调整手写笔位置实现手写笔充电或使用，或者将不是手写笔的其他物体或电子产品与终端设备远离，避免其干扰终端设备。
第二方面，本申请的实施例提供了一种手写笔检测方法，应用于终端设备，所述终端设备上设置有用于吸附手写笔的第一区域，所述手写笔的内部设置有用于将所述手写笔吸 附固定在所述第一区域的磁力吸附部件，所述方法包括：

具体实施方式
以下将参考附图详细说明本申请的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面，但是除非特别指出，不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外，为了更好的说明本申请，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本申请同样可以实施。在一些实例中，对于 本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本申请的主旨。
为解决上述问题，本申请提供了一种手写笔检测方法、装置及终端设备，能快速、准确地检测到第一区域吸附固定有吸附对象的情况下，对第一区域吸附的吸附对象进行检测，并根据检测结果发出对应的提示。图1示出根据本申请一实施例的手写笔检测方法的应用场景示意图。图2示出根据本申请一实施例的手写笔检测方法的流程图。图3示出根据本申请一实施例的手写笔检测方法的检测示意图。
如图1所示，终端设备100上设置有用于吸附手写笔的第一区域101，终端设备100内部或表面对应于第一区域101的位置设置有磁性部件，如磁性金属条。
如图1所示，手写笔200内部设置有至少一个磁力吸附部件，该磁力吸附部件可在手写笔200靠近或接触到第一区域101时与终端设备100的磁性部件吸引，以将手写笔200吸附固定在第一区域101处。手写笔200内部还可以设置有陀螺仪传感器等能够对其进行空间位置检测的传感器，以向终端设备反馈其第一位置信息。终端设备100与手写笔200之间可以进行蓝牙等通信连接。
如图1、图2、图3所示，该方法应用于终端设备100，该方法包括步骤S11-步骤S12。
在步骤S11中，在检测到所述第一区域吸附固定有吸附对象的情况下，对所述吸附对象进行检测，得到检测结果。
其中，可以在检测到所述第一区域101处磁场强度处于预设强度范围的情况下，确定所述第一区域101吸附固定有吸附对象300。
其中，终端设备100所能吸附固定的手写笔可以是多种多样的，可以根据不同手写笔200吸附到第一区域101时，终端设备100所能检测到的最小磁场强度和最大磁场强度，对预设强度范围进行设置。预设强度范围可以是由最小磁场强度和最大磁场强度构成的磁场强度区间，也即第一区域101处磁场强度大于或等于最小磁场强度且第一区域101处磁场强度小于或等于最大磁场强度，则确定所述第一区域101吸附固定有吸附对象300。还可以是基于最小磁场强度确定磁场强度区间，也即第一区域101处磁场强度大于或等于最小磁场强度，则确定所述第一区域101吸附固定有吸附对象300。
在一种可能的实现方式中，可以在终端设备100内部对应于第一区域101的位置设置对象检测器，如霍尔传感器等磁场传感器。以磁场传感器为例，磁场传感器用于对第一区域101的部分或全部区域进行磁场强度检测，输出磁场检测信号。终端设备100基于该磁场检测信号就可以分析得到所述第一区域101的磁场强度，进而判断其是否处于预设强度范围。
在步骤S12中，在所述检测结果为目标检测结果的情况下，发出第一提示和/或第二提示所述第一提示用于提醒用户吸附位置不准确，所述第二提示用于提醒用户手写笔的正确吸附位置。
其中，步骤S11中执行的“检测”以及对应的步骤S12中的目标检测结果、所发出的提示可以包括以下几种实现方式：
第一种实现方式：所述检测包括检测所述吸附对象的吸附位置是否准确。所述目标检测结果包括所述吸附对象的吸附位置不准确。步骤S12中可以发出第一提示和/或第二提示所述第一提示。
第二种实现方式：所述检测包括检测所述吸附对象的吸附位置是否准确、以及检测所 述吸附对象是否为手写笔，所述目标检测结果包括所述吸附对象的吸附位置不准确和所述吸附对象为手写笔。步骤S12中可以发出第一提示和/或第二提示所述第一提示。
第三种实现方式：所述检测包括检测所述吸附对象是否为手写笔，所述目标检测结果包括所述吸附对象不是手写笔。则步骤S12中可以仅发出第二提示，或者也可以发出第一提示和第二提示。
在一种可能的实现方式中，在所述检测结果为吸附目标为手写笔且手写笔的吸附位置准确的情况下，发出第三提示。所述第三提示可以用于提醒用户手写笔处于充电状态和/或已连接状态。
其中，步骤S11中对所述吸附对象的检测包括第一检测步骤、第二检测步骤、第三检测步骤中的至少一个步骤，在“检测”所包含的检测步骤不同的情况下，本申请手写笔检测方法的执行过程存在一定差异，以下通过“检测”的不同的实现方式一至六进行示例性说明。为简明下面先对第一检测步骤、第二检测步骤、第三检测步骤的执行过程进行说明后，再对实现方式一至六进行示例性说明。其中，若吸附对象并不是手写笔，而是磁铁等物体，由于物体并不能与终端设备进行通信，通过上述第一检测步骤、第二检测步骤和第三检测步骤自然可以实现各步骤的检测目的。而其他电子产品通过第一检测步骤、第二检测步骤和第三检测步骤中的至少一种步骤，也可以实现检测目的。
第一检测步骤可以包括：
向所述吸附对象发送私有消息，并监听所述吸附对象响应于所述私有消息返回的私有回复消息。其中，根据监听到的所述吸附对象对所述私有消息的响应结果可以判断出吸附对象是否为手写笔。
其中，若在发出所述私有消息后的第一预设时间内(如5s等，第一预设时间可以大于或等于吸附对象为手写笔的情况下其返回私有回复消息的间隔时长)接收到所述私有回复消息、且所述私有消息和/或所述私有回复消息满足预期条件，则可以确定所述吸附对象为手写笔。若在发出所述私有消息后的第一预设时间内未接收到所述私有回复消息和/或收到的私有回复消息不满足预期条件，则可以确定所述吸附对象不是手写笔。
其中，私有消息可以是仅吸附到终端设备上的不同手写笔能够接收并解析的消息。例如，可以预先设置私有消息的预设加密密码，并预先在手写笔中存储该预设加密密码(或者存储对应于该预设加密密码的解密密码)；或者还可以在手写笔第一次与终端设备建立通信连接之后将该预设加密密码(或者对应于该预设加密密码的解密密码)发送至手写笔以供其存储。这样，可以保证其他不是手写笔的电子产品(也即吸附对象)无法响应该私有消息，提高了手写笔识别检测的准确性。
其中，还可以预先对手写笔进行设置，以使得手写笔返回的私有回复消息中携带有能够指示该私有回复消息来自手写笔的标签，如手写笔的名称、类型等均可以作为该标签。这样，终端设备就可以基于私有回复消息中携带的标签判断发出该私有回复消息的电子产品(也即吸附对象)是否为手写笔，提高了手写笔识别检测的准确性。
这样，预期条件可以包括私有消息已经通过预设加密密码加密的和/或返回的私有回复消息“带有对应于手写笔的标签”，反之即为不满足预期条件。不满足预期条件可以如私有回复消息的标签不对、私有回复消息的内容无法解析、或者私有回复消息为报错消息，等等。
基于不同的私有消息发送方式，第一检测步骤可以包括第一种子检测步骤、第二种子检测步骤和第三种子检测步骤三种。
第一种子检测步骤可以包括：在确定所述吸附对象与所述终端设备之间未建立蓝牙连接的情况下，向所述吸附对象发送满足第一条件的私有消息，并监听所述吸附对象响应于满足第一条件的私有消息返回的私有回复消息。所述第一条件为所述私有消息为所述无线充电协议消息。
而由于私有消息满足第一条件，所以私有回复消息还可以反应吸附对象的吸附位置是否准确。则，若在发出所述私有消息后的第一预设时间内接收到所述私有回复消息、且所述私有消息和/或所述私有回复消息满足预期条件，则可以确定所述吸附对象为手写笔且手写笔的吸附位置准确。在发出所述私有消息后的第一预设时间内未接收到所述私有回复消息和/或收到的私有回复消息不满足预期条件，则可以确定所述吸附对象不是手写笔且吸附位置也不准确。
第二种子检测步骤可以包括：在确定所述吸附对象与所述终端设备之间已建立蓝牙连接的情况下，通过所述蓝牙连接向所述吸附对象发送私有消息，并监听所述吸附对象响应于私有消息返回的私有回复消息。而由于私有消息通过蓝牙发送，所以私有回复消息仅能反应吸附对象是否为手写笔，吸附对象的吸附位置是否准确还需要进一步检测判断。
第三种子检测步骤可以包括：向所述吸附对象发送满足第二条件的私有消息，并监听所述吸附对象响应于满足第二条件的私有消息返回的私有回复消息。第二条件包括私有消息还可以用于获取所述吸附对象的第一位置信息，私有回复消息包括所述吸附对象的第一位置信息。而后根据第一位置信息确定吸附对象与终端设备之间的相对位置关系，进而在相对位置关系满足预设条件的情况下，也可以至少初步或直接判断出吸附对象为手写笔。相对位置关系不满足预设条件的情况下，可以判断出吸附对象不是手写笔。则相对位置关系满足预设条件即为所述私有回复消息满足预期条件。
其中，所述预设条件可以包括：第一预设条件或第二预设条件。
第一预设条件为在参考坐标系中，所述吸附对象的第一位置坐标与所述终端设备的第二位置坐标的至少在一个坐标轴中的坐标值差值小于或等于预设差值。所述第一位置坐标是根据在第一预设时间内接收到的所述第一位置信息确定的。其中，预设差值可以为零。
其中，终端设备可以获取其自身陀螺仪传感器的陀螺仪数据，并将该陀螺仪数据组作为第二位置信息。而后基于确定的第二位置信息确定出终端设备100在如图3所示的坐标系OXYZ中的第二位置坐标(x2，y2，z2)。以及基于第一位置信息确定出吸附对象300在如图3所示的坐标系OXYZ中的第一位置坐标(x1，y1，z1)。而由于在吸附对象300为手写笔的情况下，第一位置坐标与第二位置坐标至少在坐标系OXYZ的一个坐标轴(如图3中的OZ轴)中的坐标值应是一致的。因此，在确定第一位置坐标和第二位置坐标的至少在一个坐标轴中的坐标值差值小于或等于预设差值，则可以确定相对位置关系满足第一预设条件。
第二预设条件为所述吸附对象300的实际空间位置与所述手写笔预测空间位置200’相同。所述实际空间位置是根据第一预设时间内接收到的所述第一位置信息确定的，所述手写笔预测空间位置200’是根据所述终端设备100的第二位置信息、所述第一区域101相对于所述终端设备100的第三位置信息确定的。第三位置信息可以包括第一区域101的尺寸、 第一区域101的中心等任意一个点在终端设备100上位置，等等。可以根据所述第一位置信息，确定所述吸附对象300的实际空间位置。实际空间位置可以为吸附对象300的中心等吸附对象上任意点的空间位置，还可以是能够表示吸附对象上每个点在空间中的位置的空间位置集合。
例如，如图3所示，终端设备100可以基于第二位置信息确定出终端设备100的实际空间位置，如，终端设备100的中心等点在坐标系OXYZ中的第二位置坐标(x2，y2，z2)。而后基于第一区域101的第三位置信息就可以预测出手写笔吸附在第一区域101的情况下，该被吸附的手写笔对应的手写笔预测空间位置200’(x0，y0，z0)。再基于第一位置信息确定出吸附对象300在如图3所示的坐标系OXYZ中的第一位置坐标(x1，y1，z1)(也即吸附对象300的实际空间位置)。若(x1，y1，z1)与(x0，y0，z0)相同,则确定相对位置关系满足第二预设条件。其中，(x1，y1，z1)与(x0，y0，z0)相同可以是指x1＝x0±δ0，y1＝y0±δ1，z1＝z0±δ2。δ0、δ1、δ2为手写笔吸附固定在第一区域101时的允许误差。
在一种可能的实现方式中，由于第一位置信息能够指示吸附对象的实际空间位置，在第一位置信息能够达到对吸附对象的吸附位置的检测标准的情况下，基于第一位置信息还可以判断吸附对象的吸附位置是否准确，若此种情况下若确定相对位置关系满足预设条件，则不但可以确定吸附对象是否为手写笔、还可以确定该手写笔的吸附位置准确。
第二检测步骤可以包括：向所述吸附对象300发送连接诊断消息，并监听所述吸附对象300响应于所述连接诊断消息返回的诊断回复消息。所述连接诊断消息包括无线充电协议消息。所述无线充电协议包括Qi协议(无线充电联盟(Wireless Power Consortium，Qi)推出的“无线充电”标准)、PMA协议(Power Matters Alliance)、A4WP协议(Alliance for Wireless Power)，等等。其中，连接诊断消息可以为ping消息(通信连接探测包)等消息。终端设备100可以基于监听到的吸附对象针对该连接诊断消息的响应结果，确定吸附对象的吸附位置是否准确，进而确定吸附对象与终端设备之间的通信连接和/或充电所需的连接是否已经正常连接。
其中，若在发出所述连接诊断消息后的第二预设时间内未接收到所述诊断回复消息，则可以确定所述吸附对象的吸附位置不准确。若在发出所述连接诊断消息后的第二预设时间内接收到所述诊断回复消息，则可以确定所述吸附对象的吸附位置不准确。第二预设时间可以为5s等，第二预设时间可以大于或等于吸附对象为手写笔的情况下其返回针对回复消息的间隔时长。
第三检测步骤可以包括：终端设备可以获取目标传感器发出的目标检测信号。进而可以基于所述目标检测信号确定所述吸附对象是否为手写笔和/或确定所述吸附对象的吸附位置是否不准确。
“检测”实现方式一：“检测”包括第一检测步骤和第二检测步骤。且所述第二检测步骤在所述第一检测步骤的第一检测结果为所述吸附对象为手写笔的情况下执行。
图4示出根据本申请一实施例的手写笔检测方法对应于“检测”实现方式一的流程图。如图4所示，通过“检测”实现方式一实现手写笔检测的方法包括步骤S101-步骤S108。
在步骤S101中，进行针对第一区域的吸附对象检测。吸附对象检测的方式可以参照上文利用第一区域磁场强是否处于预设强度范围的方式实现。
在步骤S102中，判断第一区域101是否吸附固定有吸附对象。在第一区域固定有吸附对象的情况下执行步骤S103。在第一区域101没有吸附固定吸附对象的情况下继续执行步骤S101。
在步骤S103中，执行第一检测步骤。其中，该第一检测步骤可以是上文所述的第一种子检测步骤、第二种子检测步骤和第三种检测步骤中的任意一种。
在步骤S104中，判断吸附对象是否为手写笔。
其中，在第一检测步骤为第一种子检测步骤的情况下，由于私有消息满足第一条件，所以私有回复消息还可以反应吸附对象的吸附位置是否准确。则，若在发出所述私有消息后的第一预设时间内接收到所述私有回复消息、且所述私有消息和/或所述私有回复消息满足预期条件，则可以确定所述吸附对象为手写笔且手写笔的吸附位置准确，则可以直接执行步骤S108。而若在发出所述私有消息后的第一预设时间内未接收到所述私有回复消息和/或收到的私有回复消息不满足预期条件，则可以确定所述吸附对象不是手写笔且吸附位置也不准确，可以直接执行步骤S105。
在第一检测步骤为第二种子检测步骤的情况下，若在发出所述私有消息后的第一预设时间内接收到所述私有回复消息、且所述私有消息和/或所述私有回复消息满足预期条件，则可以确定所述吸附对象为手写笔，并继续执行步骤S106。若在发出所述私有消息后的第一预设时间内未接收到所述私有回复消息和/或收到的私有回复消息不满足预期条件，则可以确定所述吸附对象不是手写笔，则继续执行步骤S105。
在第一检测步骤为第三种检测步骤的情况下，若在发出所述私有消息后的第一预设时间内接收到所述私有回复消息、且所述私有消息和/或根据私有回复消息确定的相对位置关系满足预设条件，则可以确定所述吸附对象为手写笔，并继续执行步骤S106。若在发出所述私有消息后的第一预设时间内未接收到所述私有回复消息和/或根据收到的私有回复消息确定的相对位置关系不满足预设条件，则可以确定所述吸附对象不是手写笔，则继续执行步骤S105。
在步骤S105中，发出与第一检测步骤对应的第一提示和/或第二提示。
其中，在第一检测步骤为第二种子检测条件或第三种子检测步骤的情况下，步骤S105可以发出第二提示。在在第一检测步骤为第一种子检测步骤的情况下，步骤S105可以发出第一提示和/或第二提示。
在步骤S106中，在仅确定出吸附对象为手写笔的情况下，还需要进一步执行第二检测步骤，以进一步执行步骤S107判断手写笔的吸附位置是否准确。
在步骤S107中，判断手写笔的吸附位置是否准确。若在发出所述连接诊断消息后的第二预设时间内未接收到所述诊断回复消息，则可以确定所述吸附对象的吸附位置不准确，可以继续执行步骤S105。若在发出所述连接诊断消息后的第二预设时间内接收到所述诊断回复消息，则可以确定所述吸附对象的吸附位置不准确，可以继续执行步骤S108。
在步骤S108中，发出第三提示。
其中，第三提示还用于提醒用户所述手写笔处于充电状态和/或待使用状态。
在一种可能的实现方式中，发出第三提示，可以包括以下至少一种操作：在所述终端 设备的显示屏中显示所述第三提示。以对应于所述第三提示的方式进行震动。以对应于第三提示的方式响铃。以对应于第三提示的方式发光，如闪灯。发出对应于第三提示的语音。
