Description

手柄及其按键反馈力的矫正方法、控制装置及存储介质
本申请要求于2021年05月12日提交中国专利局、申请号为202110519644.1、发明名称为“手柄及其按键反馈力的矫正方法、控制装置及存储介质”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
本发明涉及游戏设备技术领域，特别涉及一种手柄及其按键反馈力的矫正方法、控制装置及存储介质。
背景技术
随着游戏设备硬件的升级换代，现代游戏手柄扳机按键增加了力反馈效果，游戏设计者们可以利用扳机按键的力反馈效果模拟一些游戏场景，增加游戏中用户在某些场景的沉浸效果。例如，可以利用扳机按键模仿射弓场景，游戏体验者在拉弓这一过程中能真实感受到力的作用效果，再就是射击游戏中扣动扳机等场景，通过扳机按键的反馈力，给用户带来更好的体验效果。
现有的手柄包括按键组件和滑动变阻器，所述按键组件包括弹性组件和按键，所述弹性组件具体为弹簧，所述弹簧的一端被限位固定，所述弹簧的另一端与所述按键的内侧抵接，以在所述按键受压后驱动所述弹性组件变形，所述滑动变阻器的滑片与所述弹性组件被所述按键作用的一端连接，以随同所述弹性组件活动，在所述按键受压时，所述按键会压制所述弹性组件变形，以带动滑动变阻器运动，导致滑动变阻器的阻值发生变化，通过滑动变阻器阻值获取得知反馈给扳机按键的力大小。

本发明提供一种手柄，如图1所示，所述手柄100包括按键组件1、滑动变阻器2和控制装置，所述按键组件1包括弹性组件11和按键12，所述弹性组件11具体为弹簧，且所述按键组件1还包括供所述弹簧套设的顶柱13，所述弹性组件11的一端被限位固定，所述弹性组件11的另一端与所述按键12的内侧抵接，以在所述按键12的作用下驱动所述弹性组件11变形，所述滑动变阻器2的滑片21与所述弹性组件11被所述按键12作用的一端连接，以随同所述弹性组件11活动，所述控制装置与所述滑动变阻器2电性连接。进一步如图1所示，为了对所述手柄100的按键反馈力进行矫正，通过一步进电机3运动压缩顶柱13上的弹簧，以模拟扳机按键对弹簧的作用，电机运动压缩弹簧，由于弹簧的弹力进而作用给一个反馈力，由于步进电机3上下移动，进而带动滑动变阻2器运动，导致滑动变阻器2的阻值发生变化，通过滑动变阻器2阻值获取得知弹簧的反馈给按键12的力大小，即作用给按键12的反馈力是由于压缩弹簧而来，压缩量越大，反馈力也越大，而弹簧行程量与滑动变阻器2阻值成正比，而由于滑动变阻器2的位移量与阻值理想情况下是线性相关的，但是在实际使用过程中，由于结构装配误差、滑动变阻器2本身线性一致性较差等原因，导致根据真实电阻值计算得出的反馈力精度并不高，同时为了保证不同产品之间反馈力大小的一致性，需要对扳机按键进行力校准。
为此，本发明提供的技术方案可以解决上述技术问题，其主要构思为：根据按键的需求反馈力值F、以及按键的反馈力值与弹性组件的形变位移之间的设定关系，计算与F对应的所述弹性组件的形变位移S，根据所述形变位移S、以及滑动变阻器的实际电阻值与所述弹性组件的形变位移之间的映射关系，获得与所述形变位移S对应的滑动变阻器的实际电阻值R 实际，以实现对滑动变阻器的电阻值进行矫正，进而完成对扳机按键的反馈力进行矫正。以下结合本发明的具体实施例对本发明提供的技术方案进行展开说明。

本发明还提供一种手柄的按键反馈力的矫正方法，图3至图9为本发明提供的手柄的按键反馈力的矫正方法的实施例。
图3为本发明提供的手柄的按键反馈力的矫正方法的一实施例的流程示意图，请参照图3，本发明提供一种手柄的按键反馈力的矫正方法，包括：
步骤S10、根据按键的需求反馈力值F、以及按键的反馈力值与弹性组件的形变位移之间的设定关系，计算与F对应的所述弹性组件的形变位移S；
按键的需求反馈力值F为针对不同的游戏设置的按键力，或者同一种游戏针对不同用户或者不同的效果所设置的按键的需求反馈力，按键的反馈力值与弹性组件的形变位移之间显然存在设定关系，该设定关系理论上应该是线性关系，该关系可以通过胡克定律得知F＝K*X得知。
步骤S20、根据所述形变位移S、以及滑动变阻器的实际电阻值与所述弹性组件的形变位移之间的映射关系，获得与所述形变位移S对应的滑动变阻器的实际电阻值R 实际。
将用户的需求馈力值F转化为形变位移S之后，可以根据所述形变位移S获得与所述形变位移S对应的滑动变阻器的实际电阻值R 实际，系统中存储有滑动变阻器的实际电阻值与所述弹性组件的形变位移之间的映射关系，该映射关系时通过实验获得，具体后续部分有介绍。
本发明提供的技术方案中，根据按键的需求反馈力值F、以及按键的反馈力值与弹性组件的形变位移之间的设定关系，计算与F对应的所述弹性组件的形变位移S，根据所述形变位移S、以及滑动变阻器的实际电阻值与所述弹性组件的形变位移之间的映射关系，获得与所述形变位移S对应的滑动变阻器的实际电阻值R 实际，以实现对滑动变阻器的电阻值进行矫正，进而完成对扳机按键的反馈力进行矫正。
图4为图3中的步骤S10的一种实施方式的流程示意图，请参阅图4，在本实施例中，步骤S10包括：
步骤S11、根据所述需求反馈力值F、所述按键的反馈力值与所述滑动变阻器的电阻值之间的理论映射关系，计算获得与F对应的所述滑动变阻器的理论电阻值R 理论；
根据胡克定律得知F＝K*X，当扳机按键保持在初始位置，使用校准机器去接触扳机按键会得到一个初始按压力F1，根据胡克定律，在K未知的情况下，假设得出F＝F1时对应的位移为X1，然后产品端发送指令去获取扳机按键在没有触发时的滑动变阻器电阻值R1；之后，电机运动到压缩弹簧量的最大位置，使用校准机器去接触扳机按键，并获取此时的反馈力。假设产品的最 大反馈力为F2，则产品电机根据校准机器得到的反馈力大小去不断调整位置，直到电机运动到反馈力为F2的位置，并获取此时滑动变阻器的电阻值R2。假设此时压缩弹簧的行程为X2，△X＝X2-X1，由于电阻值变化与压缩弹簧量的位移行程成线性相关，既能得到△X＝(R2-R1)/M，根据胡克定律:
F2＝K*(X1+△X)；
所以：F2＝F1+K(R2-R1)/M，进而得到F2-F1＝K(R2-R1)/M,
所以：K/M＝(F2-F1)/(R2-R1)。
假设电机运动到某一位置X3，此位置从X1位置运动到X3位置压缩的弹簧量行程为△X1，对应从产品端得到此时的电阻值为R，则F3＝KX3＝K(X1+△X1),即F3-F1＝K*(R-R1)/M，F1已知，K/M也已知，所以能根据此公式算出电阻值为R时所对应的反馈力F，相应地，可以通过反馈力F，计算出对应的滑动变阻器的理论电阻值R 理论。
步骤S12、根据所述理论电阻值R 理论、以及所述滑动变阻器的电阻值与所述弹性组件的形变位移之间的理论映射关系，计算获得与F对应的所述弹性组件的形变位移S。
当理论电阻值R 理论计算出来之后，进而可以所述滑动变阻器的电阻值与所述弹性组件的形变位移之间的理论映射关系，计算获得与F对应的所述弹性组件的形变位移S，而该理论映射关系，可以通过按键在初始位置和最大行程位置时，对应的弹性组件的形变位移和滑动变阻器的电阻，计算出理论位移电阻斜率K，进而，可以根据理论位移电阻斜率K和理论电阻值R 理论，计算出与F对应的所述弹性组件的形变位移S。
图5为图3中的步骤S20的一种实施方式的流程示意图，请参阅图5，在,本实施例中，步骤S20包括：
步骤S21、将所述弹性组件的形变位移S与多个预设的弹性组件的形变位移区间进行比较；
系统会将弹性组件的形变位移S划分为多个区间，如图9所示，在一实施例中，将形变位移划分为8个形变位移区间，当然理论上划分的区间越多，最终获得的实际电阻值R 实际的精确度越高。
步骤S22、找出所述形变位移S所属的形变位移区间[S1，S2]；
将所述形变位移S与各个形变位移区间进行比较，以可以获得对应所属的形变位移区间[S1，S2]；
步骤S23、根据所述形变位移区间[S1，S2]、以及滑动变阻器的实际电阻值与所述弹性组件的形变位移之间的映射关系，计算获得滑动变阻器的实际电阻值R 实际。
在每一个形变位移区间[S1，S2]，系统都存储有滑动变阻器的实际电阻值与所述弹性组件的形变位移之间的映射关系，可以直接获得滑动变阻器的实际电阻值R 实际。
图6为为图5中的步骤S23的一种实施方式的流程示意图，请参阅图6，在本实施例中，步骤S23包括：
步骤S231、当所述形变位移S处在[S1，S2]中的第一区间段时，则其对应的电阻矫正值为R11，则对应的实际电阻值R 实际＝R 理论+R11；
步骤S232、当所述形变位移S处在[S1，S2]中的第二区间段时，则其对应的电阻矫正值为R12，则对应的实际电阻值R 实际＝R 理论+R12；
步骤S233、当所述形变位移S处在[S1，S2]中的第N区间段时，则其对应的电阻矫正值为R1n，则对应的实际电阻值R 实际＝R 理论+R1n。
也即系统在对应所述形变区间[S1，S2]的不同区间段存储有不同的电阻矫正值，该电阻矫正值时通过实验获得的。
图7为图5中的步骤S22之前的又一实施方式的流程示意图，请参阅图7，在本实施例中，步骤S22之前，还包括：
步骤S22a、将所述弹性组件最大的形变位移划分为多个区间；
步骤S22b、将各区间分为多个区间段；
步骤S22c、根据滑动变阻器的电阻值与所述弹性组件的形变位移之间的理论映射关系和实际映射关系，计算获得各个区间段所对应的电阻矫正值。
反馈力大小能根据目前滑动变阻器的电阻值算得，但是实际过程中，滑动变阻器阻值与形变位移之间线性相关性并不理想，图8为实际过程中电阻阻值与形变位移之间的关系。从图中可以看出，实际的电阻位移关系与理想的电阻位移关系存在较大误差，需要将理想的电阻位移关系校准成实际的电阻位移关系，此图是当电机在反馈力为F2(最大反馈力位置)对应的电阻值位置 时，电机开始匀速朝初始位置R1运动，并且产品端实时输出电阻值，直到运动到电阻值等于R1的位置时立刻停止，绘制的位移阻值关系图，假设运动速度为V＝1m/s，则图8中位移S＝V*T＝T。
由于在游戏场景中扳机的反馈力可调，根据算法实现，已知条件是反馈力，能根据公式计算出理论的电阻值，但是理论的电阻值要经过校准，这样才能根据实际的反馈力算出产品扳机的实际电阻值，校准位移阻值关系如图9所示，所有直线上的阻值点都要校准到对应的实际的曲线上的阻值点，即R2点要校准到R1点。根据图9所示的已知条件，可以根据实际初始点位置(即扳机反馈力最小位置)坐标M与终点坐标N(即扳机反馈力最大位置)，计算出理想位移电阻斜率K。本方法是将位移轴等分成多8段，然后找到每段位移初始位置与终点位置对应的电阻值，再根据理想的位移电阻斜率K，计算得出理论的电阻值，并根据曲线得到S1位置分别对应的实际电阻值R1，及对应的理论电阻值R2；S2位置分别对应的实际电阻值为R3，对应的理论电阻值为R4，以此得到8组(S1，R1-R2)、(S2，R3-R4)等类似数据。
在本发明的另一实施例中，步骤S20包括：
步骤S24、根据所述形变位移区间[S1，S2]，获得在形变位移区间[S1，S2]内，滑动变阻器的实际电阻值与所述弹性组件的形变位移之间等效直线关系的斜率值k1；
步骤S25、根据所述形变位移S以及所述斜率值k1，计算获得获得所述实际电阻值R 实际。
也即，在该实施例中，对于各个形变位移区间，对应存在有滑动变阻器的实际电阻值与所述弹性组件的形变位移之间等效直线关系的斜率值，该斜率值可以通过将滑动变阻器的电阻值与所述弹性组件的形变位移的实际映射关系上获得，具体地，步骤S24之前，还包括：
步骤S24a、将所述弹性组件最大的形变位移划分为多个区间；
步骤S24b、根据所述滑动变阻器的电阻值与所述弹性组件的形变位移之间的实际映射关系，计算所述多个区间的两个端点对应的实际电阻值；
步骤S24c、根据所述多个区间的两个端点的形变位移和实际电阻值，计算获得各个所述区间对应的斜率值。
也即，如图9所示，可以将获得的电阻值位移的实际映射关系曲线按照形变位移分为多段，然后，在该曲线上找到每一段的两个端点对应地电阻值，进而，可以根据电阻值和位移值算出该段的斜率值。
本发明还提出一种计算机可读的存储介质，所述计算机可读的存储介质上存储有手柄的按键反馈力的矫正程序，所述手柄的按键反馈力的矫正程序被处理器执行时实现如上述任一实施例的手柄的按键反馈力的矫正方法的步骤，在此不再赘述。
