具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
针对现有技术振动触觉体验应用场景中的，用户触觉体验不理想以及用户体验被降低的问题，本申请提供了一种振动驱动信号生成方法。为了提出本申请实施例的方法，发明人首先分析基于振动效果实现触觉体验的实际应用场景。
一般的，在基于振动效果实现触觉体验的技术方案中，应用程序会生成用于驱动振动电机的振动驱动信号，电机在振动驱动信号的驱动下运行，从而实现振动触感。然而，在实际应用场景中，不同的应用场景所对应的振动触感是不同的，如果使用统一的振动触感，势必达成理想的用户触觉体验。因此，在一种可行的触觉体验应用方案中，在通过振动效果实现触觉体验时，通过强度的变化来实现不同的振动效果，从而带来多样的触觉体验，以适配多种不同的触觉体验应用场景，提高用户体验。
进一步的，基于上述方案，虽然可以实现根据不同的触觉体验应用场景，选用不同的振动效果设定。但是，在实际应用场景中，可供选择的振动效果通常是由预先设计好并集成在设备中的。由于预先设定好的振动效果十分有限，其不可能覆盖所有的触觉体验应用场景需求，因此预设的振动效果不可能完美匹配所有的触觉体验应用场景。这就导致在某些触觉体验应用场景中，预设的振动效果不能为用户带来理想的触觉体验。
例如，在一应用场景中，设备的使用环境为较安静的场所，相较吵闹环境而言，当前应用场景下用户对振动触感的感知更为敏锐。而在通常的厂商设定中，振动效果并未对使用环境的吵闹程度进行区分。在该应用场景下，在用户触发振动触感时，如果应用程序直接调用厂商设定中振动效果设定来生成振动驱动信号，最终产生的振动效果往往会令用户产生“吓一跳”的感觉。
进一步的，在预先设定振动效果时，由于需要令预设的振动效果设定的覆盖面尽可能的广泛，因此，预先设定的振动效果设定无法对用户个人的触觉习惯进行针对性的设定。而在不考虑用户个人触觉习惯的情况下，在某些应用场景中，预设的振动效果不仅不能为用户带来理想的触觉体验，还有可能会降低用户体验。
例如，针对某一用户，相较于大多数人，该用户对振动触感的感知相对迟钝。在该用户触发振动触感时，如果应用程序直接调用预设中振动效果设定来生成振动驱动信号，最终产生的 振动效果往往会无法被该用户所清晰感知。又例如，针对某一用户，相较于大多数人，该用户对振动触感的感知相对敏感。在该用户触发振动触感时，如果应用程序直接调用预设中振动效果设定来生成振动驱动信号，最终产生的振动效果很有可能会令用户感觉到疼痛。
基于上述分析，导致用户触觉体验不理想以及用户体验被降低的问题的原因之一在于，用于实现用户触觉体验的振动效果与触觉体验应用场景需求和/或用户触觉体验需求并不匹配。因此，如果可以根据具体的触觉体验应用场景需求和/或用户触觉体验需求来修正应用程序所生成的振动驱动信号，使得最终的振动效果匹配触觉体验应用场景需求和/或用户触觉体验需求，就可以解决用户触觉体验不理想的问题并提高用户体验。
基于上述分析，在本申请一实施例中，提出了一种振动驱动信号生成方法。在本实施例的方法中，基于触觉体验应用场景需求和/或用户触觉体验需求，从信号强度、强度的变化模式、强度变化速度的变化模式三方面对应用程序所生成的振动驱动信号进行调整，以获取新的振动驱动信号，使用新的振动驱动信号驱动电机以生成可以实现匹配触觉体验应用场景需求和/或用户触觉体验需求的振动效果。
以下结合附图，详细说明本申请各实施例提供的技术方案。
图1所示为根据本申请振动驱动信号生成方法一实施例的流程图。在本申请一实施例中，如图1所示，振动驱动信号生成方法包括：
步骤110，获取匹配触觉体验应用场景需求和/或用户触觉体验需求的用户振动触感参数，该用户振动触感参数包括：初始强度调整参数，其用于调整驱动信号的初始信号；强度变化参数，其用于描述驱动信号的强度随时间的变化模式；速度变化参数，其用于描述驱动信号的强度变化速度随时间的变化模式；
步骤120，获取原始驱动信号，原始驱动信号用于驱动电机实现默认振动触感；
步骤130，根据用户振动触感参数以及原始驱动信号计算第一驱动信号，其中：
第一驱动信号的初始信号为，根据初始强度调整参数调整原始驱动信号的初始信号而生成的第一初始信号；
第一驱动信号的强度随时间的变化模式以及强度变化速度随时间的变化模式分别为，强度变化参数以及速度变化参数所描述的强度随时间的变化模式以及强度变化速度随时间的变化模式。
根据上述方法流程，由于用户振动触感参数匹配触觉体验应用场景需求和/或用户触觉体验需求，因此，基于用户振动触感参数调整原始驱动信号所计算获取的第一驱动信号所实现的振动效果就可以满足触觉体验应用场景需求和/或用户触觉体验需求。相较于现有技术，根据上述实施例的方法，可以为用户提供更优的触觉体验，提高用户触觉体验的理想度，提高用户体验。
图2所示为根据本申请一实施例的数据流走向示意图。如图2所示，用户振动触感参数201被输入到数据处理器210，数据处理器210从存储器202中读取原始驱动信号。
数据处理器210根据用户振动触感参数以及原始驱动信号计算生成第一驱动信号220，第一驱动信号220被输出到马达230以实现振动效果。
进一步的，在本申请一实施例中，初始强度调整参数包括强度倍数。第一初始信号为按照强度倍数放大或缩小原始驱动信号的初始信号而生成的信号。具体的，在步骤130一种实现方 式中，在根据初始强度调整参数调整原始驱动信号的初始信号以生成第一初始信号的过程中，按照强度倍数放大或缩小原始驱动信号的初始信号以生成第一初始信号。
例如，在一应用场景中，在根据步骤130一种实现方式的应用场景中，在根据初始强度调整参数调整原始驱动信号的初始信号以生成第一初始信号的过程中，读取储存器中的原始驱动信号后，将整段信号放大或缩小s 1倍，上述过程中s 1值即为初始强度调整参数中强度倍数的设定值。
又例如，在一应用场景中，在根据步骤130一种实现方式的应用场景中，在根据初始强度调整参数调整原始驱动信号的初始信号以生成第一初始信号的过程中，读取储存器中的原始驱动信号后，将整段信号的振动幅值放大或缩小s 2倍，上述过程中s 2值即为初始强度调整参数中强度倍数的设定值。
进一步的，考虑到振动幅值的变化会直接导致振动强度的变化，因此，在本申请一实施例中，通过调节振动幅值来调节振动强度。具体的，在强度变化参数中定义用于描述驱动信号的振动幅值随时间的变化模式的参数。
具体的，考虑到幅值渐变是一种常见的强度变化方式。因此，在本申请一实施例中，强度变化参数包括用于描述幅值渐变方式的幅值渐变参数。
在本申请其他实施例中，强度变化参数也可以包含用于描述其他幅值变化方式的参数，例如，用于描述幅值周期性变化的具体变化方式的幅值周期变化参数。
具体的，在本申请一实施例中，强度变化参数包括用于描述振动幅值增强速度或振动幅值减弱速度的第一幅值渐变参数。第一驱动信号的强度的变化模式为：从第一驱动信号的起始到结束，按照第一幅值渐变参数的振动幅值增强速度增强第一初始信号的振动幅值或者按照第一幅值渐变参数的振动幅值减弱速度减弱第一初始信号的振动幅值。即，在步骤130一种实现方式中，在生成第一初始信号的过程中，从信号的起始到结束，按照第一幅值渐变参数的振动幅值增强速度增强第一初始信号的振动幅值或者按照第一幅值渐变参数的振动幅值减弱速度减弱第一初始信号的振动幅值以生成第一驱动信号。
具体的，在本申请一实施例中，强度变化参数包括用于描述振动幅值终值的第二幅值渐变参数。第一驱动信号的强度的变化模式为：从第一驱动信号的起始到结束，按照第一预设增量规则增强第一初始信号的振动幅值或者按照第一预设减量规则减弱第一初始信号的振动幅值，使得第一驱动信号结束时的振动幅值为振动幅值终值。即，在步骤130一种实现方式中，在生成第一驱动信号的过程中，从信号的起始到结束，按照第一预设增量规则增强第一初始信号的振动幅值或者按照第一预设减量规则减弱第一初始信号的振动幅值，使得信号结束时的强度为振动幅值终值以生成第一驱动信号。
具体的，在上述实施例中，第一预设增量规则以及第一预设减量规则可以为任意增量/减量规则。例如，维持固定的增量值/减量值进行阶梯式增量/减量，或者，维持固定的增量速度/减量速度进行线性增量/减量，或者，将强度保持为特定增量/减量曲线。
例如，在步骤130一种实现方式中，在生成第一驱动信号的过程中，从信号的起始到结束，维持不变的振动幅值增强速度增强第一初始信号的振动幅值或者维持不变的振动幅值减弱速度减弱第一初始信号的振动幅值，使得信号结束时的强度为振动幅值终值以生成第一驱动信号。
具体的，在本申请一实施例中，强度变化参数包括第三幅值渐变参数。第一驱动信号的强 度的变化模式为：从第一驱动信号的起始到结束，按照第二预设增量规则增强第一初始信号的振动幅值或者按照第二预设减量规则减弱第一初始信号的振动幅值，使得第一驱动信号结束时的强度为第三幅值渐变参数的参数值所对应的强度。即，在步骤130一种实现方式中，在生成第一驱动信号的过程中，从信号的起始到结束，按照第二预设增量规则增强第一初始信号的振动幅值或者按照第二预设减量规则减弱第一初始信号的振动幅值，使得信号结束时的强度为第三幅值渐变参数对应的强度以生成第一驱动信号。
例如，在一应用场景中，第三幅值渐变参数的设定值范围为[0～+∞]，其中：
第三幅值渐变参数的设定值越大，对应的强度越大；
当第三幅值渐变参数的设定值为0时，对应的强度为0；
当第三幅值渐变参数的设定值为1时，对应的强度为第一初始信号的强度；
当第三幅值渐变参数的设定值为+∞时，对应的强度最大。
具体的，在本应用场景中，提供开放的参数接口以获取第三幅值渐变参数的设定值为+∞时所对应的振动幅值终值。当第三幅值渐变参数的设定值为+∞时，振动幅值终值为振动设备所能实现的最大强度。
具体的，在上述实施例中，第二预设增量规则以及第二预设减量规则可以为任意增量/减量规则。例如，维持固定的增量值/减量值进行阶梯式增量/减量，或者，维持固定的增量速度/减量速度进行线性增量/减量，或者，将强度保持为特定增量/减量曲线。
例如，在步骤130一种实现方式中，在生成第一驱动信号的过程中，从信号的起始到结束，维持不变的振动幅值增强速度增强第一初始信号的振动幅值或者维持不变的振动幅值减弱速度减弱第一初始信号的振动幅值，使得信号结束时的强度为第三幅值渐变参数对应的强度以生成第一驱动信号。
图3所示为根据本申请一实施例的第三幅值渐变参数设定示意图。如图3所示，第三幅值渐变参数的设定值为参数值α。当第三幅值渐变参数α设置为1时，表示信号结束时强度与信号起始时一致，保持不变；当第三幅值渐变参数α设置为0时，表示信号结束时强度最弱为0；当第三幅值渐变参数α设置为+∞时，表示信号结束时强度最强。由于强度输入值不可能输入+∞，这里提供一种开放的参数接口，获取第三幅值渐变参数的设定值为+∞时所对应的振动幅值终值。当第三幅值渐变参数的设定值为+∞时，振动幅值终值为振动设备所能实现的最大强度。
进一步的，考虑到速度渐变是一种常见的强度变化速度的变化方式。因此，在本申请一实施例中，速度变化参数包括用于描述速度渐变方式的速度渐变参数。
在本申请其他实施例中，速度变化参数也可以包含用于描述其他速度变化方式的参数，例如，用于描述强度变化速度周期性变化的具体变化方式的速度周期变化参数。
具体的，在一实施例中，速度变化参数包括用于描述强度变化速度的增强速度或强度变化速度的减弱速度的第一速度渐变参数。第一驱动信号的强度变化速度的变化模式为：从第一驱动信号的起始到结束，按照强度变化速度的增强速度增加第一初始信号的强度变化速度或者按照强度变化速度的减弱速度减小第一初始信号的强度变化速度。
具体的，在步骤130一种实现方式中，在生成第一初始信号的过程中，从信号的起始到结束，按照强度变化速度的增强速度增加第一初始信号的强度变化速度或者按照强度变化速度的 减弱速度减小第一初始信号的强度变化速度以生成第一驱动信号。
具体的，在一实施例中，速度变化参数包括用于描述强度变化速度终值的第二速度渐变参数。第一驱动信号的强度变化速度的变化模式为：从第一驱动信号的起始到结束，按照第三预设增量规则增加第一初始信号的强度变化速度或者按照第三预设减量规则减小第一初始信号的强度变化速度，使得第一驱动信号结束时的强度变化速度为强度变化速度终值。即，在步骤130一种实现方式中，在生成第一驱动信号的过程中，从信号的起始到结束，按照第三预设增量规则增加第一初始信号的强度变化速度或者按照第三预设减量规则减小第一初始信号的强度变化速度，使得第一驱动信号结束时的强度变化速度为强度变化速度终值。
例如，在一应用场景中，第二速度渐变参数的设定值范围为[-∞～+∞]，其中：
第二速度渐变参数的设定值越大，强度变化速度终值越大；
当第二速度渐变参数的设定值为0时，强度变化速度终值为第一初始信号的强度变化速度；
当第二速度渐变参数的设定值为+∞时，强度变化速度终值为振动设备所能实现的最大强度变化速度；
当第二速度渐变参数的设定值为-∞时，强度变化速度终值为振动设备所能实现的最小强度变化速度。
具体的，在上述实施例中，第三预设增量规则以及第三预设减量规则可以为任意增量/减量规则。例如，维持固定的增量值/减量值进行阶梯式增量/减量，或者，维持固定的增量速度/减量速度进行线性增量/减量，或者，将强度保持为特定增量/减量曲线。
例如，在步骤130一种实现方式中，在生成第一驱动信号的过程中，从信号的起始到结束，维持不变的变化速度增加速度增加第一初始信号的强度变化速度或者维持不变的变化速度减小速度减小第一初始信号的强度变化速度，使得第一驱动信号结束时的强度变化速度为强度变化速度终值。
图4所示为根据本申请一实施例的第二速度渐变参数设定示意图。如图3所示，第二速度渐变参数的设定值为β。当第二速度渐变参数β设置为0时，表示信号结束时强度的变化速度与信号起始时强度的变化速度一致，全程为匀速变化；当第二速度渐变参数β大于0时，表示信号结束时强度的变化速度比信号起始时强度变化速度小(β越大，信号结束时强度的变化速度越小)；当第二速度渐变参数β小于0时，表示信号结束时强度的变化速度比信号起始时强度变化速度大(β越小，信号结束时强度的变化速度越大)。
进一步的，基于上述实施例的实现过程，在步骤130的一种实现过程中，只需要参考原始信号的信号起始时的振动幅值以及强度变化速度。因此，在根据步骤130一种实现方式的应用场景中，在根据初始强度调整参数调整原始驱动信号的初始信号以生成第一初始信号的过程中，读取储存器中的原始驱动信号后，将原始驱动信号的信号起始振动幅值放大或缩小s 3倍，上述过程中s 3值即为初始强度调整参数中强度倍数的设定值。
进一步的，在步骤130的一种实现方式中，根据用户振动触感参数以及原始驱动信号计算第一驱动信号的过程，包括：
根据初始强度调整参数、强度变化参数以及速度变化参数生成加权包络线；
使用加权包络线与原始驱动信号进行乘法运算以生成第一驱动信号。
图5所示为根据本申请一实施例的计算第一驱动信号的流程图。如图5所示：
步骤510，获取输入参数s(强度倍数)、α(第三幅值渐变参数)、β(第二速度渐变参数)；
步骤520，读取原始驱动信号U0；
步骤530，根据参数s、α、β计算加权包络曲线p；
步骤531，对加权包络曲线p以及原始驱动信号U0执行相乘运算，获取第一驱动信号；
步骤540，输出第一驱动信号。
具体的，在上述步骤530的一种实现方式中，计算包络曲线p，公式如下：
当β≥0时：

当β<0时：
Figure PCTCN2020132979-appb-000002
上述公式(1)以及(2)中，t为时间变量，T为原始信号时长，s、α、β分别为输入的强度倍数、第三幅值渐变参数、第二速度渐变参数，p为加权包络曲线。
图6所示为根据本申请一实施例计算获取的幅值渐强包络线图。在一具体的应用场景中，根据上述公式(1)以及(2)计算获取的幅值渐强包络线如图6所示。图6中，横坐标为时间、纵坐标为强度。标号601所指的两条曲线表示振动信号的幅值渐强但是强度变化速度变化渐慢；标号602所指的曲线表示振动信号的幅值渐强但是强度变化速度均匀；标号603所指的两条曲线表示振动信号的幅值渐强但是强度变化速度变化渐快。
图7所示为根据本申请一实施例计算获取的第一驱动信号波形图。在一具体的应用场景中，根据本申请一实施例计算获取的第一驱动信号如图7所示。图7中，横坐标为时间、纵坐标为驱动信号的电压信号强度。如图7所示，驱动信号的幅值渐强。
进一步的，在本申请一实施例中，由用户自定义用户振动触感参数。具体的，在步骤110的一种实现方式中，提供用于输入用户振动触感参数的交互界面，根据第一用户的输入数据确定第一用户的用户振动触感参数。
例如，提供如图3或图4所示的显示界面，用户通过在图3或图4所示界面上选定参数α或β所对应的位置来实现α或β参数值的输入。
进一步的，在本申请一实施例中，根据用户的触感体验反馈来进行振动效果的调整。具体的，在步骤110的一种实现方式中，获取第二用户的振动触感反馈数据，根据第二用户的振动触感反馈数据确定第二用户的用户振动触感参数。
进一步的，在本申请一实施例中，根据当前的应用场景来确定匹配应用场景需求的用户振动触感参数。具体的，在步骤110的一种实现方式中，获取原始驱动信号的应用场景描述，根据应用场景描述确定用户振动触感参数。
可以理解的是，上述实施例中的部分或全部步骤骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
进一步的，基于本申请一实施例中提出的振动驱动信号生成方法，本申请一实施例还提出了一种振动驱动信号生成装置。图8所示为根据本申请振动驱动信号生成装置一实施例的结构图。在本申请一实施例中，如图8所示，在本申请一实施例中，振动驱动信号生成装置800 包括：

图8所示的本申请一实施例提供的装置可用于执行本申请实施例的方法实施例的技术方案，其实现原理和技术效果可以进一步参考方法实施例中的相关描述。
进一步的，在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由访问方对器件编程来确定。由设计人员自行编程来把一个数字装置“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式 实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
在本申请实施例的描述中，为了描述的方便，描述装置时以功能分为各种模块/单元分别描述，各个模块/单元的划分仅仅是一种逻辑功能的划分，在实施本申请实施例时可以把各模块/单元的功能在同一个或多个软件和/或硬件中实现。
具体的，本申请实施例所提出的装置在实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且这些模块可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分模块以软件通过处理元件调用的形式实现，部分模块通过硬件的形式实现。例如，检测模块可以为单独设立的处理元件，也可以集成在电子设备的某一个芯片中实现。其它模块的实现与之类似。此外这些模块全部或部分可以集成在一起，也可以独立实现。在实现过程中，上述方法的各步骤或以上各个模块可以通过处理器元件中的硬件的集成逻辑电路或者软件形式的指令完成。
例如，以上这些模块可以是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个特定集成电路(Application Specific Integrated Circuit，ASIC)，或，一个或多个数字信号处理器(Digital Singnal Processor，DSP)，或，一个或者多个现场可编程门阵列(Field Programmable Gate Array，FPGA)等。再如，这些模块可以集成在一起，以片上装置(System-On-a-Chip，SOC)的形式实现。

具体的，在本申请一实施例中，处理器可以和存储器可以合成一个处理装置，更常见的是彼此独立的部件，处理器用于执行存储器中存储的程序代码来实现本申请实施例所述方法。具体实现时，该存储器也可以集成在处理器中，或者，独立于处理器。
