附图概述
图1为本发明实施例所提供的投影播放方法流程示意图；
图2为本发明实施例的投影播放装置结构示意图。
本发明的较佳实施方式
为了给出有效的实现方案，本发明提供了下述实施例，以下结合说明书附图对本发明实施例进行说明。
本发明实施例首先提供一种投影显示方法，包括如图1所示的步骤：
步骤101：接收投影播放者的声音信号，并将声音信号解析为字符信息；
所述声音信号为模拟连续信号；
步骤102：查找所述字符信息对应的目标对象；
步骤103：在当前播放的投影界面中，查找到所述字符信息对应的目标对象后，修改所述目标对象的显示参数，使得所述目标对象从预设的第一显示状态切换到预设的第二显示状态。
从上面所述可以看出，本发明实施例提供的投影显示方法，能够根据投影播放者的声音信号在当前投影界面中显示出播放者正在讲解的内容，无需播放者手动指示或者控制键盘等输入装置；同时，播放者的讲解进度可以精确地显示在播放界面，当当前播放界面上存在较多的内容时，投影观看者也能直观地看到播放者当前的讲解进度，方便观看者观看。
在本发明实施例中，所述步骤101可以在播放者讲述、讲解投影播放文件的任何时刻持续执行，也可以在接收到触发信号的情况下执行。例如，播放者可以向一个手势指令接收装置发送手势指令，在接收到该指令时，开始采集播放者的语音信号。
在本发明实施例中，接收到播放者的语音信号之后，识别出语意，，然后获得播放者语音信号对应的字符信息，例如文本。所述识别方式包括：模糊模式识别。
在本发明实施例中，从所述第一显示状态切换到第二显示状态，指采用设定的第二显示方式将所述对象突出显示出来，使得观看者能够直观得知播放者当前的讲解进度，所述第二显示方式包括：放大显示、高亮显示、采用特殊的显示效果进行显示、改变字体等等。
所述目标对象为字符对象或非字符对象；查找所述字符信息对应的目标对象的步骤包括：
当当前播放的投影界面中存在非字符对象时，从当前播放的投影界面中的非字符对象属性信息中提取该非字符对象对应的字符内容；
将所述非字符对象对应的字符内容和当前播放界面所显示的所有字符内容作为查找对象，从查找对象中查找播放者声音信号解析的字符内容；
当当前查找对象中存在与所述声音信号解析的字符信息相同程度满足预设条件时，确定满足所述预设条件的对象为目标对象。
在本发明实施例中，所述字符对象指可直接识别为字符的对象，如标题、文字段落等。所述非字符对象指不可直接识别为字符的对象，如图片等。对于非字符对象，可对其添加字符属性，例如，设置一个与非字符对象关联的隐藏标签，使得当确定该对象为非字符对象时，能够从关联的标签中提取出
对应的字符内容。
在本发明实施例中，若当前播放界面中不存在图片对象，仅存在文字对象，则在当前播放界面的文字对象中查找与播放者声音信号解析的字符内容对应的对象。若当前播放内容中存在图片对象，则可以从该图片对象预设的属性信息中提取字符内容。可选的，播放者在制作投影材料时，可以设置于图片对象对应的一个属性信息或标签等，例如，“图1”、“增长趋势线图”等，在播放者讲述“图1”或“增长趋势线图”时，根据播放者的语音信号解析出相应的字符信息，若该字符信息与当前播放界面中的图片所预设的属性信息或标签中的文字信息一致时，将该图片按照预设的方式改变显示状态，例如，将该图片背景突出显示。
在本发明实施例中，投影播放的文件中可能存在表格等对象，在一些情况下，所述表格对象包括一系列字符。在另一些情况下，所述表格对象可能为非字符对象，表格中的内容不可识别。
在本发明实施例中，由于播放者讲解播放界面时所说的内容往往与播放界面上所显示的内容不会百分之百相同，因此，可设置一定的条件，当一个对象满足这个条件，例如，当一个对象与所述字符信息的相似程度达到一定的百分比时，认为该对象为目标对象。
在本发明实施例中，播放者在讲解播放界面的内容时，可能所讲的语句识别出的字符信息与当前播放界面上的对象相似，但该对象并非播放者讲解进度所对应的对象，为防止这种情况，可设置一个较为严格的条件，使得当播放者讲述的内容所解析的字符信息与当前播放界面上的对象之间存在较高相似度时，才将所述对象确定为目标对象。
在本发明实施例中，查找所述字符信息对应的目标对象的步骤之后，还包括：
在当前投影播放界面不存在所述字符信息对应的目标对象、且在与当前播放界面处于设定页数范围内的界面存在与所述字符信息对应的目标对象时，将当前播放界面切换为包括所述目标对象的界面，并在切换后的播放界面中修改目标对象的显示方式，使得所述目标对象从预设的第一显示状态切换到预设的第二显示状态。
在本发明实施例中，播放者一般会按照投影播放文件中页面设置顺序讲解，因此，所述设定页数范围为当前播放界面的下一界面。也就是说，在本发明实施例中，在当前投影播放界面不存在所述字符信息对应的目标对象、且在当前播放界面的下一界面中存在与所述字符信息对应的目标对象时，将当前播放界面切换为包括所述目标对象的界面，并在切换后的播放界面中修改目标对象的显示方式，使得所述目标对象从预设的第一显示状态切换到预设的第二显示状态。
由于在一些情况下，当前播放界面与其它界面可能存在相同或相似的字符信息，为了避免执行错误的切换，在当前播放界面中不存在与播放者语音信号解析所得的字符信息相对应的目标对象时，才进一步判断是否在其它设定页数范围内的播放界面是否存在与所述字符信息对应的目标对象。
在本发明实施例中，将当前播放的投影界面中，将播放者已讲述过的对象、未讲述的对象、正在讲述的对象采用不同的显示参数进行显示，使得三者处于不同的显示状态。
在实际情况下，可能会因为外界因素、播放者讲解进度等原因导致观看者可能在观看投影界面的过程中出现中断，而同时，由于播放者有可能重复讲述以讲述过的内容，因此，在本发明上述实施例中，将已播放内容、未播放内容区分显示，使得观看者能够随时直观查看到播放者的讲解进度。
在本发明实施例中，在当前播放界面查找到目标对象之后，将此目标对象从第一显示状态改变为第二显示状态，当检测到播放者的下一语音信号在当前播放界面存在另一目标对象时，改变原目标对象的显示状态，将新目标对象从第一显示状态改变为第二显示状态。此时，前一目标对象为已讲述过的对象，当前目标对象为正在讲述的对象，为改变过显示状态的对象为未讲述的对象。
在本发明实施例中，查找所述字符信息对应的目标对象的步骤之后，还包括：
在当前投影播放界面不存在所述字符信息对应的目标对象、且在与当前播放界面处于设定页数范围之内的界面不存在与所述字符信息对应的目标对象时，不改变当前显示状态。
在本发明实施例中，所述设定页数可以是当前投影播放界面的前后一页或几页；由于播放者在讲解投影播放文件时一般是按照投影界面顺序进行讲解，回到已讲解过的投影界面重新讲解的情况较少，因此所述设定页数也可以是当前播放界面的后一页或后几页。
由于播放者在讲述投影文件时，可能会涉及很多内容，而在一个投影文件中，相同或相似的内容可能会在不同的多个播放界面出现，播放者讲述过程中可能会因为这样的原因错误地触发播放界面的切换，因此，需要将目标对象的搜索范围缩小，降低错误切换的可能性。
本发明实施例提供一种投影显示装置，结构如图2所示，包括：
声音信号接收模块：设置为接收投影播放者的声音信号；
声音信号解析模块：设置为将声音信号解析为字符信息；
目标对象查找模块：设置为查找所述字符信息对应的目标对象；
第一显示状态更改模块：设置为在当前播放的投影界面中，查找到所述字符信息对应的目标对象时，修改所述目标对象的显示参数，使得所述目标对象从预设的第一显示状态切换到预设的第二显示状态。
在本发明实施例中，所述目标对象为字符对象或非字符对象；所述目标对象查找模块包括：
非字符对象识别单元：设置为当当前播放的投影界面中存在非字符对象时，从当前播放的投影界面中的非字符对象属性信息中提取该非字符对象对应的字符内容；
匹配单元：设置为将所述非字符对象对应的字符内容和当前播放界面可直接识别的所有字符内容作为查找对象，从查找对象中查找播放者声音信号解析的字符内容；
目标对象确定单元：设置为当当前查找对象中存在与所述声音信号解析的字符信息相同程度满足预设条件时，确定满足所述预设条件的对象为目标对象。
在本发明实施例中，所述装置还包括：
界面切换模块：设置为在当前投影播放界面不存在所述字符信息对应的
目标对象、且在与当前播放界面处于设定页数范围内的界面存在与所述字符信息对应的目标对象时，将当前播放界面切换为包括所述目标对象的界面；
第二显示状态更改模块：设置为在切换后的播放界面中修改目标对象的显示方式，使得所述目标对象从预设的第一显示状态切换到预设的第二显示状态。
在本发明实施例中，所述装置还包括：
显示状态控制模块：设置为将当前播放的投影界面中，将播放者已讲述过的对象、未讲述的对象、正在讲述的对象采用不同的显示参数进行显示，使得三者处于不同的显示状态。
在本发明实施例中，所述显示状态控制模块还设置为：在当前投影播放界面不存在所述字符信息对应的目标对象、且在与当前播放界面处于设定页数范围之内的界面不存在与所述字符信息对应的目标对象时，不改变当前显示状态。
应当理解，本说明书所描述的多个实施例仅用于说明和解释本发明，并不用于限定本发明。并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的各装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的各装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
上述技术方案使得观看者可以直观得知播放者讲解的进度。此外，上述技术方案还能够将当前播放界面切换到存在所述讲解目标对象的播放界面，实现播放界面的自动切换。
