一种智能穿戴设备及其信息输入方法 技术领域
本发明涉及智能设备技术领域，具体涉及一种智能穿戴设备及其信息输入方法。
发明背景
目前，在智能穿戴设备(如智能手表)领域,由于屏幕尺寸较小,采用传统输入法不利于用户输入操作。很多厂家转而选择采用语音输入的方法，但是语音输入在某些使用场景下存在诸多限制。例如在嘈杂的环境下，外部噪声会对语音输入的准确性产生影响，导致智能穿戴设备无法准确识别出用户语音指令；或者智能穿戴设备使用过程中有很多需要保密的场景(如开机密码输入、网上银行密码输入等)，这时使用语音输入的方法容易造成重要信息的泄露。所以，在智能穿戴设备的领域，手动信息输入在某些使用场景下仍然具有不可替代性。
但是，由于智能穿戴设备的屏幕尺寸较小，用户在智能穿戴设备的小尺寸屏幕上手动输入信息时，点击、选择等操作不便并容易导致输入失误，用户体验较差。
发明内容
本发明提供了一种智能穿戴设备及其信息输入方法，以解决现有的智能穿戴设备的屏幕尺寸较小，用户信息输入操作不便、用户体验较差的问题。

辅触控板设置在智能穿戴设备的至少一侧的侧面，主屏幕触控板设置在智能穿戴设备的正面；
当智能穿戴设备处于输入状态时，辅触控板和主屏幕触控板，分别接收用户的触控指令；
触控芯片，检测主屏幕触控板以及辅触控板，获取触控指令，分别对触控指令进行处理后发送给微控制单元；
微控制单元，设置输入法应用的每一图层中切换各控件的触控事件与辅触控板的触控指令之间的第一映射关系；以及设置输入法应用的切换不同图层的触控事件、输入确认触控事件、输入删除触控事件与主屏幕触控板的触控指令之间的第二映射关系；根据第一映射关系、接收到的辅触控板的触控指令，以及第二映射关系、接收到的主屏幕触控板的触控指令，实现智能穿戴设备的信息输入。
根据本发明的另一个方面，提供了一种智能穿戴设备的信息输入方法，智能穿戴设备的正面设置有主屏幕触控板，至少一侧面设置有辅触控板；当智能穿戴设备处于输入状态时，信息输入方法包括：
利用辅触控板接收用户输入的第一触控指令，利用主屏幕触控板接收用户输入的第二触控指令；
检测主屏幕触控板以及辅触控板，获取第一触控指令和第二触控指令，并对第一触控指令和第二触控指令进行处理后输出；

本发明的有益效果是：本发明实施例的技术方案，由于在智能穿戴设备至少一侧面设置有辅触控板以及在正面设置有主屏幕触控板，并配置输入法应用每一图层中各控件间切换的事件与辅触控板的触控指令的第一映射关系，以及配置不同图层切换的触控事件、输入确认触控事件、输入删除触控事件与主屏幕触控板的触控指令之间的第二映射关系；然后利用第一映射关系和第二映射关系，在接收到主屏幕触控板或者辅触控板的触控指令时，实现对应的信息输入。这样，通过主屏幕触控板和辅触控板的分工配合，分别接收用户的触控指令，实现了将主屏幕触控板的触控功能进行延伸，突破了 智能穿戴设备屏幕尺寸的限制，并避免了仅通过主屏幕触控板进行信息输入时容易导致的误操作问题，提高了用户使用体验。

具体实施方式
本发明的设计构思在于：针对现有技术中智能穿戴设备屏幕尺寸较小，手动信息输入操作不便、容易误操作、用户体验差的问题，通过在智能穿戴设备至少一侧面设置辅触控板，并使辅触控板分担部分信息输入功能，再配合主屏幕触控板的信息输入功能，实现智能穿戴设备的信息输入。如此，解决了小尺寸屏幕的智能穿戴设备的信息输入时容易发生错误操作，点击、滑动等操作不便，用户体验差的问题。另外，应用本发明实施例的技术方案后，智能穿戴设备的屏幕也可以保持现有的小尺寸设计或者设计成更小的尺寸，从而满足了智能穿戴设备的屏幕设计多样化需求，提高了产品的竞争力。
图1a是本发明一个实施例的一种智能穿戴设备的框图，参见图1a，本发明一个实施例中，智能穿戴设备100包括：主屏幕触控板102、辅触控板101、触控芯片103和微控制单元104；
辅触控板101设置在智能穿戴设备100的至少一侧的侧面，主屏幕触控板102设置在智能穿戴设备100的正面；
当智能穿戴设备100处于输入状态时，辅触控板101和主屏幕触控板102，分别接收用户的触控指令；
触控芯片103，检测主屏幕触控板102以及辅触控板101，获取触控指令，分别对触控指令进行处理后发送给微控制单元104；
微控制单元104，设置输入法应用的每一图层中切换各控件的触控事件与辅触控板101的触控指令之间的第一映射关系；以及设置输入法应用的切换不同图层的触控事件、输入确认触控事件、输入删除触控事件与主屏幕触控板102的触控指令之间的第二映射关系；根据第一映射关系、接收到的辅触控板101的触控指令，以及第二映射关系、接收到的主屏幕触控板102的触控指令，实现智能穿戴设备100的信息输入。
图1b是本发明一个实施例的一种智能穿戴设备的使用场景示意图，结合图1a和图1b，在本实施例中，智能穿戴设备100为智能手表。主屏幕触控板102与辅触控板101均与触控芯片103连接；触控芯片103通过I2C总线与微控制单元104连接；辅触控板101包括：柔性电路板FPC(参见图1b所示)，柔性电路板上设置有多个串联的金属电极，各金属电极之间连接有寄生电容；寄生电容还与触控芯片103的输出引脚连接。考虑到实际应用场景中辅触控板是设置在智能穿戴设备的至少一侧的侧面，所以辅触控板的大小不会太大，优选地，本实施例中，柔性电路板上设置有四个金属电极，四个金属电极已经能够满足准确检测触控点位置的需求。该柔性电路板上胶贴塑料件后(这里的塑料件可为聚酰胺Polyamid eP，简称PA)，嵌入至智能手表100的表盘壳体的侧部。
在图1a和图1b所示的智能穿戴设备100上，设置了主屏幕触控板102和辅触控板101且两个触控板共同连接至同一个触控芯片103，由于现有的智能穿戴设备的屏幕尺寸有限，在侧边设置辅触控板并分担部分输入功能相当于把主屏幕触控板空间进行了延伸，主屏幕触控板和侧面的辅触控板配合共同实现信息输入，从而解决了现有技术中智能穿戴设备屏幕尺寸小，手动输入操作不便、容易误操作的问题，优化了用户使用体验，提高了智能穿戴 设备的竞争力。
本实施例中的这种智能穿戴设备的输入法功能的实现过程如下：智能穿戴设备中设置有许多应用程序，用户在使用智能穿戴设备并打开某些应用程序时，将弹出输入法界面，输入法应用程序对应虚拟键盘，由键盘按键监听程序实时监听键盘动作。用户在主屏幕触控板上每一个点击动作或在辅触控板上的每一个滑动动作都会通过触控芯片产生触控信息，触控芯片通过I2C接口将触控信息传递给微控制单元(MCU)。
输入法管理器(Input Method Manager，简称IMM)是连接输入法程序和其他应用程序的桥梁，IMM中包含有UI控件，输入法的用户界面UI(User Interface，简称UI)遵循层级结构，每一个层级的按键所在位置信息都存在UI控件中。当键盘按键监听程序监测到有按键动作时，被触发位置信息经过UI控件转化为按键消息。同时，应用程序(如智能穿戴设备上的拨号应用程序，短信应用程序等)将通过IMM告知系统。这些按键消息将通过输入法接口传递给输入法编辑器(Input method Editor，简称IME)。输入法编辑器收到按键消息后，调用逻辑函数对按键消息进行计算，把按键消息转化为字符消息或命令消息，字符消息发送给输入法管理器IMM，以便在应用程序的输入界面中显示；命令消息发送给输入法程序以进行输入法界面的切换、确认、返回等。
图2是本发明一个实施例智能穿戴设备输入法应用的初始图层中各控件切换的示意图，参见图2，本实施例中，输入法应用的初始图层中设置有输入栏控件、输入类型标识控件和控制控件；
具体的，输入类型标识控件包括：英文输入标识控件、中文输入标识控件、数字输入标识控件和符号输入标识控件，以便用户选择具体的输入类型。
需要说明的是，图2所示的符号输入标识控件即为特殊符号输入类型标识控件。
当智能穿戴设备处于初始输入状态时，输入法应用首先启动的是初始图层，在该初始图层上设置有图2所示的多个控件。设置在智能穿戴设备一侧面的辅触控板(即侧边Touch)响应于用户的滑动操作，生成滑动触控指令。与辅触控板相连的触控芯片，实时检测辅触控板，获取辅触控板上的滑动触 控指令，将该滑动触控指令处理后发送给微控制单元MCU。MCU接收触控芯片发送的滑动触控指令，并根据MCU中已设置的第一映射关系，在输入法应用的初始图层上不同输入类型标识控件间切换。这里的第一映射关系可以是：根据辅触控板的滑动触控指令，实现同一输入图层中不同控件间的选择、切换事件。
参见图2，本实施例中，用户通过辅触控板输入的滑动触控指令选择某一输入类型标识控件。然后，MCU根据第一映射关系以及接收到滑动触控指令，改变输入法应用当前图层中被选择的输入类型标识控件的用户界面显示信息，以提示用户当前选中的输入类型标识。
在本实施例中，MCU将用户选择的输入类型标识控件的显示信息设置为高亮，以突出显示，在其他实施例中也可以将显示信息设置为其他形式，对此不做限制。
参见图2，控制控件包括：确定控件和返回控件；微控制单元，根据第二映射关系以及接收到的对确定控件的点击触控指令，确认辅触控板的滑动触控指令选择的输入类型标识控件触发成功，并启动该输入类型标识控件对应的输入图层；或者，根据第二映射关系以及接收到的对返回控件的点击触控指令，退出输入法应用的初始图层。输入法应用的初始图层上设置确定控件(即ok键)和返回控件(即C键)，在选择了输入类型标识控件后，主屏幕触控板响应于用户的点击操作，生成点击触控指令。触控芯片实时检测主屏幕触控板，获取到点击触控指令，将点击触控指令处理后发送给MCU。
本实施例中，点击触控指令可以是确定控件的点击触控指令或者返回控件的点击触控指令，MCU根据第二映射关系以及具体的点击触控指令实现相应的操作。这里的第二映射关系可以为：输入法应用的输入确认事件或者输入法应用不同图层切换的触控事件与主屏幕触控板的点击触控指令间的映射关系。
具体的，当主屏幕触控板响应用户的点击操作，生成确定控件的点击触控指令时，MCU控制确认当前图层中被选择的输入类型标识控件触发成功，并启动进入该输入类型标识控件对应的输入图层。当主屏幕触控板响应于用户的点击操作，生成返回控件的点击触控指令时，MCU控制退出输入法应 用的当前图层。
在本发明的其他实施例中，对返回控件的点击触控指令还可以实现输入法应用不同图层间的切换(下面再具体说明)，由于这里是以输入法应用的初始图层为例进行的说明，所以当用户在主屏幕触控板点击返回控件时，对应的操作为退出输入法应用的初始图层。
图3a至3d是在图2所示的输入法应用初始图层中各输入类型标识控件对应的输入图层的示意图，其中，图3a表示英文输入标识控件对应的输入图层，图3b表示中文输入标识控件对应的输入图层，图3c表示数字输入标识控件对应的输入图层，图3d表示特殊符号输入标识控件对应的输入图层。
由图3a至图3d可以看出，每个输入类型标识控件下对应的输入图层中都对应有多个输入字符控件，方便进行滑动选择。
以下，以一次信息输入内容的过程为例(输入字符“L”)，对本发明实施例这种结构的智能穿戴设备的功能进行具体说明。
参见图2和图3a，进入图2所示的输入图层后，辅触控板接收输入的滑动触控指令选择了英文输入标识控件，MCU将英文输入标识控件高亮显示并启动进入英文输入标识控件对应的输入图层。进入到英文输入标识控件对应输入图层后(即图3a所示的输入图层)，辅触控板响应用户的滑动操作，生成滑动触控指令。MCU根据第一映射关系以及滑动触控指令，在当前图层中的多个输入字符控件间选择、切换。
图4是在图3a所示的英文输入类型标识控件对应的输入图层中输入字符选择的示意图，参见图4，辅触控板响应于用户的滑动操作，生成滑动触控指令，触控芯片检测辅触控板，获取滑动触控指令并处理后发送给MCU，MCU根据第一映射关系，在不同输入字符控件间选择、切换。
英文输入标识控件对应的输入图层中包括：输入字符控件、输入栏控件和控制控件。具体的，输入字符控件是以字符组控件的形式呈现的，也就是说，在图4所示的输入图层中，每个输入字符控件上都存储有一个字符组，例如用户当前选中的呈高亮显示的输入字符控件上设有一组字符“LMNOP”，每个字符组控件对应的输入图层下还对应设置单个字符控件对应的图层，以此来减少对智能穿戴设备屏幕尺寸的占用，降低对屏幕尺寸的限制。
由图4、图3可知，本实施例中的智能穿戴设备的输入法应用采用层级结构，根据辅触控板的滑动操作，实现同一图层间不同控件的切换，通过主屏幕触控板的点击操作实现输入法应用不同图层间切换操作、输入确认操作以及输入删除操作。具体的，通过辅触控板(即侧边Touch)实现同一图层内的选择，确定键ok确认进入下一图层，返回键C返回上一图层；输入法应用的初始图层设置几个输入类型，通过滑动侧边Touch来实现不同输入类型间的切换，通过主屏幕触控板点击确定键ok进入某一个大类(输入类型)；在每一个大类中，再设置分字符组控件；比如英文26个字母，可以划分成四或五个字符组控件，同样的，滑动侧边Touch选择相应的字符组控件，点击确定键ok确认；进入该字符组控件对应的图层后点击要输入的单个字符控件。这种层级结构的输入法应用以及主屏幕触控板、辅触控板配合的方案，保证了智能穿戴设备的屏幕尺寸可以设计的较小，并且解决了小尺寸屏幕信息输入容易误操作的问题。
此外，参见图4，英文输入标识控件对应的输入图层上还设置有大小写切换控件、标点符号控件满足用户的信息输入需求。
参见图4，当用户选择了当前图层上的字符“LMNOP”所在的输入字符控件对应的输入图层后，主屏幕触控板响应于用户的点击操作，生成点击触控指令，触控芯片实时检测主屏幕触控板，获取到该点击触控指令并进行处理后发送给MCU，MCU根据第二映射关系以及接收到的点击触控指令进行相应的操作。
例如，当主屏幕触控板根据用户的点击操作生成的点击触控指令是对确定控件(即ok键)的点击触控指令时，MCU确认辅触控板的滑动触控指令选择的输入字符控件(即LMNOP所在的输入字符控件)触发成功，并启动该输入字符控件对应的输入图层。当主屏幕触控板根据用户的点击操作生成的点击触控指令是对返回控件(即C键)的点击触控指令时，MCU控制输入法应用返回到图3a所示的输入图层，使得输入法应用从字符组控件对应的输入图层切换到输入类型标识控件对应的输入图层。即主屏幕触控板生成的返回控件的点击触控指令实现输入法应用不同图层间的切换事件。
本实施例中，以用户在图4所示的主屏幕触控板上点击ok控件为例继续 说明，MCU确认辅触控板的触控指令选择的输入字符控件触发成功，进入该输入字符控件对应的输入图层。
图5是在图4所示输入字符控件对应的输入图层中选择单个字符的示意图；结合图4和图5，在图4所示的输入图层中将26个英文字母分为5个字符组，滑动侧边Touch的在英文输入界面的各字符组之间进行切换。图4中的高亮显示的字符组为选中项。滑动侧边Touch到相应的字符组后点击确定控件ok，进入图5所示的输入图层。进入图5所示的输入图层后，点击字符“L”，将字符“L”发送给输入框显示输入的字符。如果未收到用户点击字母，或发现要输入的字母不在当前输入图层时，则可以接收用户滑动侧边Touch的滑动操作，以返回图4所示的图层。返回到图4所示的图层后可滑动侧边Touch选择大小写切换控件，并点击确定控件ok，输入法应用将转化大写/小写模式，以输入对应的大写/小写字符。
参见图5，与前述图4和图3a中不同的是，图5是输入法应用一次输入过程中的最后一个输入图层的示意图，在该输入图层中，主屏幕触控板响应于用户的点击操作(如，点击字符“L”所在的控件)，生成点击触控指令，MCU根据主屏幕触控板的点击触控指令，将用户选择的单个输入字符发送给输入栏控件显示，如此完成了字符“L”的输入。在这一输入法图层中只需要通过主屏幕触控板接收用户的点击操作即可，省略了侧边触控板的滑动操作，MCU根据第二映射关系，确认主屏幕触控板点击触控指令选择的单个字符触发成功，而无需设置控制控件。
需要说明的是，本发明实施例中，为了保持界面的美观并考虑实际使用需求，输入法应用的最后一个输入图层中只设置了单个输入字符控件和输入栏控件，不设置返回上一图层的返回控件(即不设置返回键C)，而是通过建立输入图层切换事件与辅触控板的滑动触控指令间的第三映射关系，来实现返回上一输入图层的功能。
参见图5，在当前图层(如图5所示图层)中，如果字符输入完成后，还需要继续输入其他字符时，辅触控板响应于用户的滑动操作，生成滑动触控指令，MCU根据接收到的辅触控板的滑动触控指令以及第三映射关系，返回字符组控件对应的输入图层(即图4所示的输入图层)，后续再响应用户 重新选择字符组控件的操作。
经过上述过程，智能穿戴设备简捷迅速的完成了字符“L”的输入，接下来对输入内容的删除操作进行说明。
在智能穿戴设备的信息输入过程中，经常发生输入内容错误需要删除的场景，这时主屏幕触控板响应于用户的点击触控指令，MCU根据接收到的点击触控指令以及第二映射关系，执行输入内容的删除操作。
图6是本发明一个实施例提供的输入内容示意图，图7是对图6所示的输入内容的删除示意图。
在本实施例中，根据第一映射关系、接收到的辅触控板的触控指令，以及第二映射关系、接收到的主屏幕触控板的触控指令，实现智能穿戴设备的信息输入包括：根据主屏幕触控板的触控指令和第二映射关系，执行输入内容的删除操作。
结合图6和图7，输入法应用的当前图层的输入栏控件中显示有输入内容“Go”，主屏幕触控板接收用户点击输入栏控件的点击触控指令，MCU根据主屏幕触控板的点击触控指令以及第二映射关系，启动输入内容删除事件对应的图层(即图7所示的图层)；进入图7所示的图层后，辅触控板响应用户的滑动操作，生成滑动触控指令，MCU根据接收到的滑动触控指令，控制光标随着辅触控板上的滑动触控指令而移动，以选择待删除的输入内容，光标移动到待删除输入内容时，主屏幕触控板响应用户的点击触控指令(即点击删除控件“×”的触控指令)，并根据点击触控指令以及第二映射关系，将选中的输入内容删除。如此即完成了输入内容的删除操作。
参见图7，图7中的输入法删除操作的图层上设置了返回控件和删除控件，在完成输入内容的删除操作后，可配置主屏幕触控板响应于用户点击返回控件“C”的触控指令返回输入法的上一层级。在本发明的其他实施例中，通过辅触控板响应于用户的滑动触控指令，并根据该滑动触控指令以及微控制单元中保存的滑动触控指令与返回上一层级事件间的第三映射关系，实现返回输入法上一层级的效果。
由上可知，相对于语音输入法，手动信息输入的适用范围更广，而本发明实施例的技术方案在具备手动信息输入的优点之外，通过设置辅触控板并 配合主触控板，使得本实施例的智能穿戴设备的信息输入与现有的手动信息输入相比更加简捷迅速，解决了传统信息输入在小尺寸屏幕的智能穿戴设备上造成的误操作问题，优化了用户使用体验。
图8是本发明一个实施例的辅触控板的工作原理示意图。参见图8，在本实施例中，智能穿戴设备的硬件电路包括：在柔性电路板(Flexible Printed Circuit board，简称FPC)上设有四个金属电极82(图8中只示出了两个金属电极)，金属电极82之间有寄生电容(即电容Cp)连接。当手指81在辅触控板上滑动时，手指和金属电极之间会产生耦合电容，导致电容Cp的容值发生变化，该电容通过人体并联到地，由于电容Cp的容值的变化，触控芯片接收端的电流会随着容值的变化而改变，这时，触控芯片进行信号转换处理，将电流的变化转化为对应的数字信号后通过I2C接口发送给微控制单元MCU。
另外，本发明实施例还提供了一种智能穿戴设备的信息输入方法，智能穿戴设备的正面设置有主屏幕触控板，至少一侧面设置有辅触控板；当智能穿戴设备处于输入状态时，信息输入方法包括：

综上所述，本发明实施例的技术方案，由于设置了在正面的主屏幕触控板以及设置在至少一侧面的辅触控板，并设置辅触控板与输入法应用每一图层中控件间切换事件与辅触控板的触控指令的第一映射关系，以及设置不同图层切换的触控事件、输入确认触控事件、输入删除触控事件与主屏幕触控板的触控指令之间的第二映射关系；根据第一映射关系和第二映射关系，在接收到主屏幕触控板或者辅触控板的触控指令时，实现对应的信息输入。这样通过主屏幕触控板和辅触控板的分工合作，分别接收用户的触控指令，例如通过辅触控板接收用户在输入法应用的同一图层中选择控件的触控指令，并通过主屏幕触控板的触控指令接收用户对选择的控件进行确认得触控指令，将主屏幕触控板的触控功能进行了延伸，突破了智能穿戴设备主屏幕尺寸的限制，并避免了仅通过主屏幕触控板进行信息输入时导致的误操作问题，提高了用户使用体验。
以上所述仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所作的任何修改、等同替换、改进等，均包含在本发明的保护范围内。
